- Earth Pressure Balance Rectangular Pipe Jacking Machine accomplishes rectangular section tunneling by earth pressure balance principle, it reduces land acquisition, jacking acreage and saves project cost by its rational section structure. It can be used for the construction of crossing tunnel, highway crossing, subway station, underwater tunnel and the pipeline of electric power, communication, Petroleum, natural gas on downtown area, ancient historical preservation zone and so on.
- The full section cutting has been made on rectangular section by the machine.
- The machine can keep the earth pressure balanced and make less disturbance of soil.
- It can increase the space utilization and reduce the volume of the tunneling earth.
- Does not affect road traffic, water transportation and buildings on the ground.
- Less noise during construction. No environmental pollution.
