It combines pipe jacking with a laser-guided, steerable tunnel bore machine (TBM). Hydraulic cylinders push specially designed jacking pipes or steel casings through the ground behind the TBM, which is manned by an operator who observes soil conditions and to monitors line and grade to ensure a precise installation. … GROUTING The process of …
What is Pipe Jacking? – Definition from Trenchlesspedia
Pipe jacking is a trenchless method of new pipe installation. Factory-made pipe sections are jacked or pushed behind the tunnel boring machine or other tunnel excavation methods. Jacking force is transmitted from thrust wall installed in the drive shaft. Pipe jacking is used for the following cases.

a fabricated ring, usually made from steel, that is mounted on the first pipe of the pipe string. This ring is intended to transfer the jacking force from the microtunnel boring machine’s (MTBM’s) bearing area to the jacking pipe and to create a waterproof seal between the machine and the spigot of the first joint.
Pipe Jacking. Pipe Jacking, generally referred to in the small diameters as microtunneling, is a technique for installing underground pipelines, ducts and culverts. Powerful hydraulic jacks are used to push specially designed pipes through the ground behind a shield at the same time as excavation is taking place within the shield.
Pipe jacking is widely used for the installation of utility pipelines such as sewer, water mains, oil, gas, and electricity. It can also be used for culverts, pedestrian subways and road underpasses. Pipe Jacking How Pipe Jacking Works. With machine jacking operations, a hydraulic push unit pushes a capsule followed by the pipe through the ground.
The best ground for concrete pipe jacking is clay with a minimum 100KPa unconfined compressive strength. The higher the percentage of silt or sand in the clay, the higher the value of soil/pipe friction and consequent jacking loads. Pipe jacking is most successful in shales with good stand-up times and which
Pipe Jacking entails manual excavation from within the protective confines of a jacking shield. The jacking shield is jacked forward using high performance hydraulic jacks and once the shield has progressed far enough forward, a concrete pipe is then lowered into position behind the shield.
