Disturbance Effect of Pipe Jacking Group Adjacent

Apr 24, 2021 As jacking excavation, soil output, driving machine jacking, and other processes, the pipe jacking excavation will continue to disturb the surrounding soil along a certain angle to the ground. The complete boundary line on both sides will form a junction with the ground; thus, a lateral disturbance area forms, which is shown in Figure 2

Pipe Jacking and Utility Tunneling Methods in Trenchless

Pipe jacking method involves the installation of a pipe (prefabricated) through the ground. The driving takes place from a drive shaft to the reception shaft. The drive shaft consists of jacks, that moves the pipe. During the execution of the process, the hydraulic jack makes use of thrust power to move the pipe forward into the ground

Jacking pipes - Holcim

The jacking technique (microtunnelling) Pipe jacking is a method of tunnel construction where hydraulic jacks are used to thrust specially made pipes through the ground behind a shield machine, from launch shaft to receival shaft. The term microtunnelling is also often used to

Pipe Jacking - an overview | ScienceDirect Topics

Nov 03, 2015 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 )

Developments and research directions in pipe jacking and

Mar 01, 2020 The essential element that distinguishes pipe jacking (as compared to other tunneling methods) is that the lining of the resulting tunnel is pushed through the ground from the starting point rather than being built section-by-section just behind the excavation face or within the tail shield of a tunnel boring machine. Pipe jacking has been

AVN Machine - Herrenknecht AG

Pipe jacking over great distances. AVN Machines are often used in pipe jacking operations. The maximum drive length depends on several factors such as skin friction, available jacking force, or the nominal diameter of the jacking pipes. Automatic lubrication systems reduce the friction between pipe skin and soil by injecting bentonite into the annular gap

Pipe jacking (Microtunneling) – GEOSA

When the row of pipes exceeds a certain length and the friction forces grow, hydraulic pumping devices –called interjack stations– must be placed between pipes. Once the tunneling machine reaches the exit shaft, all essential parts of the devices can be recovered
