Pipe Jacking Machine/Tunnel Boring Machine(TBM)

Pipe jacking machine, also known as shield machine and tunnel boring machine, is a mechanical equipment used for tunnel construction and underground pipeline laying. It is mainly used for the excavation and support of tunnels and underground passages.

The working principle of pipe jacking machine is to use advanced shield technology to send the shield machine underground, drive the cutter head through the equipment to dig, eject the earth, and then transport it out of the machine through the mud conveying system. After the excavation is completed, the precast concrete pipe is entered into the tunnel to seal the pipe body and the excavation surface. At the same time, cement slurry is filled into the pipe to synergistically consolidate the soil surface around the pipe and the pipe body to support the tunnel, thereby completing tunnel excavation and pipeline construction. Paving and tunnel support.

Pipe jacking machine are mainly used in municipal and civil projects such as urban rail transit, underground water supply and drainage systems, gas, HVAC, optical cables and electric cables, subway.

The machine is a mechanical equipment used in municipal underground trenchless projects. It does not need to excavate the surface layer, and can complete the modern construction of underground pipelines across roads, railways, rivers, ground buildings, underground structures, etc. equipment. The machine consists of four parts: main jacking system, soil conveying system, grouting system and electrical system.

  Earth Balance Pipe Jacking Machine

  Earth balance pipe jacking machine is applicable to a wide range of soil.
  Low speed and high torque transmission mode is adopted, the cutting force of the cutter head is large, and the overload coefficient can reach more than.
  There is an independent and perfect soil water injection and grouting system, which can improve the soil on the excavation surface, so as to expand the scope of application.
  The construction ground settlement is small, and the minimum overburden is only 1.2 times of the pipe diameter.
