Hard Rock Pipe Jacking Machine

We are well known for manufacturing, exporting, distributing, trading and supplying of Hard Rock Pipe Jacking Machine. The pipe jacking method is one of the main method for trench less tunneling. It's based on a simple principle: the pipe string is driven from the launch shaft in the direction of the target shaft. Hydraulic jacks drive the tunneling machine which is positioned at the tip. Once the thrust cylinders have reached their final position, they are retracted. The next tunneling pipe is let down into the launch shaft, installed and then pushed forward. This process is repeated until the target shaft has been reached.
Trenchless tunneling construction has many advantages because the surface remains almost completely unaffected by the pipe jacking operations. No major earth shifting is necessary at the tunneling site and only a few shafts are required. This means in practice:
a calmost no impact on nature or the environment
a calmost no impact on traffic or roads
a calmost no impact on residents by dirt and noise
a cno risk of vibration for historic buildings
a cgreater transparency in terms of time and costs
Shanghai Mengqi Industry was established in shanghai in 1997 as one of the biggest heavy duty machinery manufacturer of China. Huayu machinery is one key subsidiary company of Mengqi positioning in manufacturing and supporting quality pipe jacking and tunneling equipment that accurately installs a variety of underground infrastructure.
