Zhenjiang Greatwall Microtunnel Equipment Science & Technology Co.,Ltd (hereinafter referred to as CCZJ) By implementing new products strategy in 2009, CCZJ successfully developed micro-tunneling technology and delivered trenchless machines to domestic market which made CCZJ the first company to manufacture and supply pipe-jacking machines in China.

Micro Tunnel Boring machine,Pipe Jacking Machine ...

Center drive Microtunnel Boring Machines (MTBMs) accurately install pipe in virtually any ground condition, and especially in high levels of ground water. MTBMs feature high pressure jetting nozzles, an articulated steering joint with three-point steering control, and hydraulically activated dirt wings to minimize MTBM roll.

Microtunnel Boring Machine (MTBM) Systems | Slurry ...

As the diagram shows that, for most pipe jacking constructions, the Microtunneling Boring Machine (MTBM) and jacking frame are set up in the starting shaft (also called launching pit) at the required depth. The operator is given constant feedback about the machine's location, orientation and devices via a computer console or CCTV camera.

The Microtunneling Procedure. Hydraulic jacks are used to push the microtunnel boring machine (MTBM) into the ground. A section of pipe or casing is put in place, slurry lines and control cables are connected and the hydraulic jacks are used to push the MTBM and pipe section into the earth.

Microtunneling - J & J Boring, Inc.

Tunnel boring machine - Wikipedia. A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling. Get A Quote

slurry microtunneling machines -

Microtunneling includes these steps: Excavate launching and reception shafts at opposite ends of the tunneling drive. Hydraulic jacks in the launch shaft push a microtunnel boring machine (MTBM) into the earth. Pipes containing slurry water transport excavated spoils to the surface; Retract the jacks and disconnect slurry lines and control cables.

Microtunneling - Accurate Installation of Gravity Flow ...

Understanding Microtunneling. Microtunneling is state of the art remote-controlled pipe jacking by computer, which is why we call it “Digital Age Tunneling”. One person above ground operates the microtunneling system using a computer to advance and steer the microtunnel boring machine, jack the pipe, and excavate the soils.

Microtunneling | Learn About Sewer Construction Methods ...

As the name implies, microtunneling or microtunnelling is a digging technique used to construct small tunnels.These small diameter tunnels make it impossible to have an operator in the machine itself. Instead, the microtunnel boring machine (MTBM) must be operated remotely.. Microtunnel boring machines are very similar to tunnel boring machines (TBM) but on a smaller scale.
