tunnel boring machine - an overview | sciencedirect topics

Because TBM tunneling produces a much smaller disturbed zone and requires much less rock support than the drilling and blasting method, more and more TBM machines are used all over the world. However, up to the present date the cost of TBM tunneling has been much higher than that of the drilling and blasting method. In order to reduce the cost of TBM, it is necessary to increase tunneling speed and cutter life. On the basis of field measurements and analysis in this chapter, it is possible to largely increase the boring speed

Tunnel boring machines (TBMs) have extreme rates of tunneling of 15 km/year and 15 m/year and sometimes even less. The expectation of fast tunneling places great responsibility on those evaluating geology and hydrogeology along a planned tunnel route. When rock conditions are reasonably good, a TBM may be two to four times faster than the drill and blast method. The problem lies in the extremes of rock mass quality, which can be both too bad and too good (no joints), where alternatives to TBM may be faster (Barton, 1999). The basic advantages of TBMs are high safety with low overbreaks, little disturbance to surrounding rock mass, and low manpower. However, set-up and dismantling time are significant and the range of available tunnel cross-section shapes is limited (Okubo, Fukui, & Chen, 2003). Engineers should not use TBMs where engineering geological investigations have not been done in detail and rock masses are very heterogeneous. Contractors can design TBMs according to the given rock mass conditions, which are nearly homogeneous

There have been continuous efforts to develop a relationship between rock mass characterization and essential machine characteristics such as cutter load and cutter wear, so that surprising rates of advance become the expected rates. Even from a 1967 open TBM, Robbins (1982) reported 7.5 km of advance in shale during four months. Earlier in the same project, 270 m of unexpected glacial debris took nearly seven months. The advance rate (AR) of 2.5 m/h has declined to 0.05 m/h in the same project. This can be explained by engineering rock mass classification. The TBM should not be used in squeezing ground conditions, rock burst conditions, and flowing grounds, because it is likely to get stuck or damaged

tunnel boring machine - an overview | sciencedirect topics

Barton (2000a) incorporated a few parameters in the Q-system that influence the performance of a TBM to obtain QTBM (i.e., rock mass quality for an open TBM). Using QTBM, Barton (2000a) believed that the performance of TBMs in a particular type of rock mass may be estimated. His approach is presented in this chapter

As the use of TBMs and micro-tunnel boring machines (MTBM) increases with advancements in tunneling technology, contractors are more and more willing to tunnel in difficult ground conditions. As a result, there have been a number of cases of tunneling machines becoming stuck or breaking down. In order to facilitate the repair and/or “rescue” of the tunneling machines and get the projects completed, ground freezing has been utilized as a method to access often very difficult locations at significant depths and/or beneath existing development and infrastructure. A few case studies of TBM rescues are reported here

A 3-foot diameter TBM became inoperable after tunneling under the Cedar River at a depth of ~ 25 ft in close proximity to the Renton Airport runway, and needed to be recovered and repaired to continue tunneling. Severe restrictions and limitations challenging this operation included equipment heights and operating times, among others. Ground freezing was successfully used to construct a stable, dry, rescue shaft to retrieve the TBM. The shoring wall was rapidly completed in two weeks. A 14-foot diameter precast manhole was then placed within the frozen shaft for future access by the repaired TBM (www.SoilFreeze.com). Figure 13.15 shows the freezing plan for this operation

In another TBM rescue operation, a machine had become disabled at a depth of about 100 m (300 ft) underground with more than 5 bars of hydrostatic pressure. Given the depth and pressure, and the fact that the stuck TBM was located beneath a residential neighborhood, it was not feasible to access it from the ground surface. The successful solution was to complete the tunnel from the opposite direction with a second machine. At the connection point, the ground was frozen around the disabled machine by installing freeze pipes from the ground surface, supplemented by freeze pipes drilled from within the tunnel (Figure 13.16). This allowed workers to access and disassemble the stuck TBM, finally completing the tunnel (Gwildis et al., 2012)

There are several types of TBMs (Fig. 4.41). The best TBM for a project is based on the geological conditions of the site and the project’s features. The general classification of the different types of TBMs for both hard rock and soft ground are presented here

A gripper TBM (Fig. 4.42) is suitable for driving in hard rock conditions when there is no need for a final lining. The rock supports (rock anchors, wire-mesh, shotcrete, and/or steel arches) can be installed directly behind the cutter head shield and enable controlled relief of stress and deformations. The existence of mobile partial shields enables gripper TBMs to be flexible even in high-pressure rock. This is useful when excavating in expanding rock to prevent the machine from jamming

tunnel boring machine - an overview | sciencedirect topics

A double-shield TBM is generally considered to be the fastest machine for hard rock tunnels under favorable geological conditions with installation of the segment lining. It is possible to drive 100 m in 1 day. This type of TBM consists of a rotating cutter head and double shields (Fig. 4.43), a telescopic shield (an inner shield that slides within the larger outer shield), and a gripper shield together with a shield tail

While boring, gripper shoes radially press against the surrounding rock to hold the machine in place and take some of the load from the thrust cylinders. For the motion of the front shield the gripper shoes are loosened, before the front shield is pushed forward by thrust cylinders protected by the extension of the telescopic shield. Because regripping is a fast process, double-shield TBMs can almost continuously drill. As for the shield tail, it is used to provide protection for workers while erecting, installing the segment lining, and pea grouting

Single-shield TBMs (Fig. 4.44) are used in soils that do not bear groundwater and where rock conditions are less favorable than for double shields, such as in weak fault zones. The shield is usually short so that a small radius of curvature can be achieved

Earth pressure balance (EPB) technology (Fig. 4.45) is suitable for digging tunnels in unstable ground such as clay, silt, sand, or gravel. An earth paste face formed by the excavated soil and other additives supports the tunnel face. Injections containing additives improve the soil consistency, reduce soil stick, and thus its workability

To ensure support pressure transmission to the soil, the earth paste is pressurized through the thrust force transfer into the bulkhead (Facesupport.org (FS), n.d.). The TBM advance rate (inflow of excavated soil) and the soil outflow from the screw conveyor regulate the support pressure at the tunnel face. This is monitored at the bulkhead by the readings of pressure sensors (Fig. 4.46)

Slurry TBMs are used for highly unstable and sandy soil and when the tunnel passes beneath structures that are sensitive to ground disturbances (NFM Technologies, n.d.). Pressurized slurry (mostly bentonite) supports the tunnel face. The support pressure is regulated by the suspension inflow and outflow. The slurry’s rheology must be chosen in accordance with the soil parameters and should be carefully and regularly monitored (FS, n.d.)

Mixshield technology (Fig. 4.47) is a variant of conventional slurry technology for heterogeneous geologies and high water pressure. In mixshield technology an automatically controlled air cushion controls the support pressure, with a submerged wall that divides the excavation chamber. This wall seals off the machine against the excess pressure from the tunnel’s face. As air is compressible in nature, the mixshield is more sensitive in pressure control and thus will provide more accurate control of ground settlement

Pipe jacking (also called microtunneling) is a micro- to small-scale tunneling method for installing underground pipelines with minimum surface disruption. It is used for sewage and drainage construction, sewer replacement and lining, gas and water mains, oil pipelines, electricity and telecommunications cables, and culverts (PJA, 2017)

A fully automated mechanized tunneling shield is usually jacked forward from a launch shaft toward a reception shaft. Jacking pipes are then progressively inserted into the working shaft. Another significant difference between the pipe jacking method and shield method is that the lining of the pipe jacking is made of tubes and the lining of the shield method is made up of segments

tunnel boring machine - an overview | sciencedirect topics

In order to significantly reduce the resistance of the pipes, a thixotropic slurry is injected into the outside perimeter of the pipes. The thixotropic slurries can also reduce disturbance to the ground while pipe jacking slurry thickness. The thickness should be six to seven times the void between the machine and pipes

Partial-face excavation machines (Fig. 4.48) have an open-face shield and can sometimes be more economical in homogeneous and semistable ground with little or no groundwater (Herrenknecht, n.d.b). In boulders layer, the open-face can deal with boulders much easier than closed shield machines. In cavity ground, the open-face can avoid the risk of falling down into the bottom of the cavity. Thanks to their simple design and that the operator workplace is close to the open tunnel face, these machines can easily be adapted to changing geological conditions. Good excavation monitoring can also be carried out

Only approximately two-thirds of a circular tunnel section can effectively be used. Consequently, the TBMs of the future are expected to have noncircular cross-sectional machines and be so-called noncircular shields. Different types already exist, such as double-O-tube shield tunneling (DOT) shields (Fig. 4.49) for which a middle column is installed in order to form a stable tunnel lining

tunnel boring machine - an overview | sciencedirect topics

Various tunnel cross sections (Fig. 4.50) can also be made using a shield machine with a primary circular disk cutter in the center and multiple secondary planetary cutters on the peripheries (Fig. 4.51)

Today, different companies have been working on developing technology that can cope with specific demands. Oil, gas, and geothermal energy sources can be explored using deep drilling rings. The Terra Invader type deep drilling rig is an efficient drilling technology used to explore deep energy deposits and can be used for onshore and offshore drills to depths of down to 8000 m (Fig. 4.52)

The performance of a TBM depends on its capacity to create the largest size of chips of rocks with the least thrust. Thus rock chipping causes high rate of tunneling rather than grinding [6]. The rate of boring through hard weathered rock mass is found to be below expectation

tunnel boring machine - an overview | sciencedirect topics

Disc cutters are used for tunneling through soft and medium hard rocks. Roller cutters are used in hard rocks, although their cost is high. A typical TBM is shown in Figure 8.2, together with ancillary equipment. The machine is gripped in place by legs with pads on rocks. Excavation is performed by a cutting head of welded steel and a convex shape, with cutters arranged on it optimally. The long body of the TBM contains four hydraulic jacks to push forward the cutting head and also drive motors that rotate the cutting head for chipping rocks. Figure 8.3 shows schematically a method of advance of the cutter head and shows how the TBM is steered and pushed ahead in self-explaining four steps. Typically, even when a TBM operates well, only 30 to 50% of the operating time is spent on boring

Figure 8.2 also shows the removal system for muck (rock chips). The excavated material is collected and scooped upward by buckets around the cutter head. These buckets then drop the rock pieces on a conveyer belt, transporting them to the back end of the TBM. There they are loaded into a train of mucking cars

The cutter forces of a small tunnel boring machine (TBM) were measured in the field [2]. According to the measured results for the normal force, most peaks of the normal force fluctuations are larger than 60 kN, and the corresponding tc=0.019−0.2 s [3]. According to the measured results [1], the fracture toughness of gabbro is KIC=3−60 MPam12. Assuming that the fracture toughness of the two rocks at Äspö underground where the TBM was boring is KIC=3−60 MPam12, then the actual loading rate of the boring machine should be

tunnel boring machine - an overview | sciencedirect topics

Similarly, since typical loading times to failure are of the order of magnitude of 100μs (ie, tc=100×10−6s) in percussive drilling [4], and the fracture toughness of general rocks is in a range of KIC=3−60 MPam12, then the loading rate of the percussive drilling machine should be [3]:

Bieniawski (2007) analyzed over 500 case histories to develop the rock mass excavability (RME) index to estimate the performance of double-shield and open-type TBMs. Excavability is defined as the rate of excavation expressed in machine performance in meters per day

Bieniawski et al. (2006) found that the parameters with stronger influence on the average rate of advance (ARA), expressed in m/day, are abrasivity (or drillability), discontinuity spacing, and stand-up time. In addition, it was decided to include the two basic rock parameters—UCS of the rock material and groundwater inflow—because in some cases these two factors strongly influence the TBM advance. Once these five parameters were selected, a weighted distribution was performed. These weights have been statistically analyzed, minimizing the error in the ARA prediction and resulting in the ratings shown in Table 6.14. Thus, the RME index is based on the five input parameters listed in the table together with the ratings associated with each

tunnel boring machine - an overview | sciencedirect topics

Out of the five parameters listed in Table 6.14, three parameters—uniaxial crushing strength, discontinuities in the front of the tunnel, and groundwater inflow—can be easily obtained by an experienced engineering geologist. For stand-up time for TBM excavated tunnels, it is required that RMR be estimated. Figure 6.1 shows the RMR chart for estimation of the stand-up time for tunnels. Since this chart was originally developed for drill and blast tunnels, the following correlation is available between the RMRD&B and RMRTBM based on the work by Alber (2000)

Construction by TBM generally results in higher RMR values than for the same tunnel section excavated by drilling and blasting because of the favorable circular shape and less damage to the surrounding rock mass by machine boring

The RME index is obtained by summation of the five input parameters in Table 6.14, which tabulates the ratings appropriate for the ranges listed. Using the RME index in Eq. (6.8), the “theoretical” average rate of advance (ARAT) in m/day of TBM can be estimated (Bieniawski et al., 2006)

tunnel boring machine - an overview | sciencedirect topics

Influence of the TBM crew (FE): The TBM crew who handles the tunneling machine every day has an important influence on the performance achieved. The adjustment factor of the TBM crew is listed in Table 6.15

Influence of the excavated length (FA): As tunnel excavation increases, the TBM performance is increased because of the adaptation of the machine. The quantitative effect of this adjustment adaptation factor (FA) is given in Table 6.16

Influence of tunnel diameter (FD): Equation (6.8) was derived for tunnels with diameters close to 10 m. Taking into account the influence of different tunnel diameters, D (in meters), on the advance rate of TBM, a coefficient (FD) is proposed as seen in Eq. (6.9) (Bieniawski, 2007).(6.9)FD=-0.007D3+0.1637D2−1.2859D+4.5158

tunnel boring machine - an overview | sciencedirect topics

Further, Bieniawski (2007) evaluated Eq. (6.10) and found that this equation gives reliable results for double-shield TBM in rock with strength less than 45 MPa and open type TBM in rock with strength more than 45 MPa. Another method of estimating the advance rate of TBM is presented in Chapter 14 based on QTBM

Fig. 6.2.2 showed an intense rockburst in the No. 3 headrace tunnel of Jinping II excavated by a tunnel boring machine (TBM). This intense rockburst occurred at 8:14 a.m. on August 18, 2010. The length of the rockburst region along the tunnel axis was about 6 m from the chainage of K10 + 350 to K10 + 356. The depth of the rockburst pit reached 1.5 m. In the rockburst region, the surrounding rock mass and supports that form the north sidewall arch in the tunnel cross section were destroyed. The rock mass was intact marble, and no structural planes exposed

Fig. 6.2.2. Intense rockburst without the existence of stiff structural planes occurred on August 18, 2010 in TBM tunnel of Jinping II hydropower station, China: (A) rockburst failure pit and (B) tensile cracks of rockmass near rockburst region

The evolution of rock mass fracturing types in the development process of this rockburst was shown in Fig. 6.2.3. Each ball in the diagram represented a microseismic event of rock mass fracturing at the corresponding time. The scale of event was related to its microseismic energy. With the increase of microseismic energy, the ball would be bigger. It can be seen that all the fracturing were tensile. There were no mixed and shear fracturing events during this rockburst evolution process

Fig. 6.2.3. Evolution of rock mass fracturing types during an intense rockburst without the existence of stiff structural planes occurred on August 18, 2010 in the TBM tunnel of the Jinping II hydropower station, China

The most explosive rock blocks have been cleaned before the field survey. However, the macrofailure characteristics of the rock mass near the rockburst region could be still observed. The failure of the surrounding rock mass showed a clear plate cracking of the tensile mechanism (see Fig.6.2.2B). Meanwhile, a small amount of explosive rock blocks related to the rockburst that was left in mesh reinforcement was all plate like, which means rock plates were formed by a tensile failure inside the surrounding rock mass in the rockburst region. In addition the surface of rockburst pit was fresh, rough, and without scratches; this was the typical feature of a tensile rupture

tunnel boring machine - an overview | sciencedirect topics

The evolution mechanism of this rockburst indicated by its microseismicity and macrofailure characteristics was consistent. In conclusion the mechanisms of rock mass fracturing during this rockburst were basically tensile

Concrete tunnels can be constructed using various tunneling methods, e.g., the cut and cover method in soft ground, tunnel boring machine (TBM) method for a rock tunnel or shield-driven tunnel in soil ground, new Austrian tunneling method (NATM) for sound ground, and immersed tube method for underneath a river or sea (JSCE, 2006a,b,c; Chapman, et al., 2010; Kuesel et al., 2012). The cut and cover method is popular to use for constructing shallow tunnels because of its relative lower cost. It involves excavating an open trench, installing in-situ concrete linings, and subsequently covering the tunnel with compacted soil to design ground level. For excavation, piles and lagging, tie back anchors, or slurry wall systems are usually used as temporary support systems, depending on the ground condition and surrounding situation in an urban area. The immersed tube tunnel method is usually used to cross a river, sea bay, etc. A trench is first dug in the bed under the water, and then, prefabricated tunnel segments are placed in the design positions and connected to adjacent segments. Finally, the trench is usually backfilled to cover the tunnel for preventing from the entry of water-borne traffic. The shield tunnel is excavated with a TBM or shield, and immediately a temporary or permanent lining system is installed to support the surrounding ground and provide a foundation for advancing the machine. Depending on the condition of the excavated ground, the boring machine can be designed as an open or a closed type, a slurry or earth pressure balanced type, using a roller or teeth cutter, etc. NATM is often considered the most cost-efficient tunneling method, because it is able to effectively integrate the surrounding ground into an overall ring-like support system. The tunnel is excavated gradually, and a composite lining (e.g., a flexible combination of rock bolts, wire mesh, steel ribs, and sprayed concrete (shotcrete) is installed immediately after the tunnel face advances, to stabilize the surrounding ground. Finally, the invert is installed to create a closed ring system for load bearing. Generally, the construction of NATM tunnel requires real-time, on-site measurement and monitoring to help determining the support system. In addition, the jacked tunnel method is often used to construct a short tunnel underneath certain obstructions, or a long pipe tunnel with a small diameter. The drill and blast method is usually applied as an alternative of the TBM method in rock situations

Well-established construction methods are available to excavate such openings, involving the use of drilling and blasting techniques or of tunnel-boring machines. The comparative attributes of these two general methods for excavating tunnels at depth in crystalline rock have been evaluated at the Aspo Hard Rock Laboratory (HRL) in Sweden (Bäckblom et al., 2004). Also, in connection with evaluations of the potential mechanical disturbance caused by excavation, various controlled blasting methods have been developed to enable the damage to the rock surface to be limited, if required. If the excavation has to pass through difficult features such as fracture zones carrying high water flows, a suite of methods has been developed to deal with these situations both from experience in underground research laboratories and in other industries. In the example of high water flows in fracture zones, grouting is likely to be used, as exemplified by the experience gained at the Aspo HRL
