[0002] Glass fiber reinforced plastic jacking pipe (GRP for short) is a new type of jacking pipe formed by continuous winding process, which is composed of resin, glass fiber (continuous + short cut) and quartz sand. Its use is the same as that of ordinary jacking pipe. In the working pit, with the help of the jacking force generated by the main jacking cylinder and other jacking equipment, the friction between the jacking pipe and the surrounding soil is overcome, and the jacking pipe is pushed into the soil according to the designed slope.

[0003] When installing the jacking pipe, after one section of the jacking pipe is pushed into the soil layer, another section of the jacking pipe is connected to the jacking pipe in the soil layer, and then the jacking pipe outside the soil layer is pushed in, so as to push multiple sections of the jacking pipe into the soil layer and splice the multiple sections of the jacking pipe.
