Ltd Rectangle EPBM Machine Time:2009-10-23 Rectangle Pipe jacking machine FEL Series of Earth pressure balance rectangle pipe jacking machine makes use of soil pressure balance principle to complete tunnel construction to rectangle cross-section, and may use for constructing under pass through street and high way ,subway station, subway,undersea tunnel and downtown area,historic reservation, vegetation conservation district ,etc. Lay down pipeline for water supply and drainage,electric power,telecommunication,oil and natural gas. Characteristic: Make use of soil pressure principle to do full-section cutting with small perturbation about soil body. At the same sectional area ,rectangle tunnel more effectively use room than round tunnel, reduce less underground tunnelling earthwork. Not need to pave ground surface,so not only save time but also reduce construction cost about 20%. There is less effect on original buildings ,such as various kinds of underground pipe line,road traffic, water transportation,etc. during operation not noisy or pollution and anytime monitor construction condition by means of PLC programming controller and various types of sensor, thus effectively control jacking axes,rotor angle deviation and ground subside of rectangle tunnel. Principle of Work: Adopt large cutter and copy cutter to do full section cutting to facing soil body, change rotating speed of screw machine and jacking speed to control discharge soil measure, make soil pressure value in soil pressure barn steady and control within the limit of pressure value given, thus soil steady to cutting surface.
