Small diameter tunnel excavation method using slurry
Basically the system involves the pushing or thrusting of a drivage machine through concrete pipes ahead of jacks. This method utilizes mud slurry that is formed around the pipes in order to stabilize the surrounding soil. Moreover, in recent years, the rectangular shape of the concrete pipe in using slurry pipejacking was introduced due to

Microtunnelling: Planning, Process, and Construction
🕑 Reading time: 1 minute Microtunnelling is an efficient trenchless technique for the construction of small diameter tunnels. The method is especially useful for laying pipelines beneath highways, railroads, and other sensitive areas with minimum disruption to businesses and traffic on the surface. It offers precise line and level installations in

Tunneling DECAST
Reinforced Concrete Microtunneling Pipe. Microtunneling is a remotelycontrolled, laserguided, pipejacking operation that provides continuous support to the excavation face by applying mechanical or fluid pressure to balance groundwater and

Tunnel Boring Machine: Working of the Tunnel
A tunnel boring machine (TBM), also known as mole, is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the

Effect of ground borne vibrations on underground
Ordinary Portland cement and builder’s sand was used at a cement/sand ratio of 1:4 for the concrete pipe. Two accelerometers were fastened at right angles in the middle of each pipe to measure the vibration of the pipe walls. Experiments on plaster of Paris model pipes were also conducted in a similar manner to the brass and concrete

Uses of concrete in conventional tunneling: overview
The method behind the concrete pour for the slab lining will depend mostly on the size of the tunnel’s section: those large enough to allow the transit and maneuvering of mixer trucks will be able to use truckmounted concrete pumps. Smallersection tunnels will require additional equipment such as longdistance pumps. Shotcrete
