The power head is adopted for jacking, the front edge of the head drives the spiral drill rod to advance, and the residue soil is discharged from the receiving pit and is easy to block the power head when encountering a clay layer, so that blind hole construction cannot be realized. 3. The muddy water balance or soil pressure balance jacking pipe is adopted to lay the pipeline, and the precision control is poor in the laying with small pipe diameter. 4. And (4) jacking the pipeline by using a pipe jacking machine, and then using a spiral drill rod to assist in unearthing.

After the 4 th pipe pushing machine pushes the pipeline into the stratum, the jacking oil cylinder is required to drive the movable frame to retract, and then jacking operation of the next guide drill rod or spiral drill rod is carried out; for the condition that the guide drill rod or the spiral drill rod needs to be pulled out of the stratum, after the guide drill rod or the spiral drill rod is pulled out, the jacking oil cylinder drives the movable frame to slide forwards and pull out the next guide drill rod or spiral drill rod. During actual construction, the sliding speed of the movable frame is set within a certain range under the influence of resistance in the jacking process and in order to avoid damage to the guide drill rod or the spiral drill rod in the jacking process or the pulling-out process, but the speed of the movable frame for withdrawing after jacking the guide drill rod or the spiral drill rod and the speed for sliding forwards after pulling out the guide drill rod or the spiral drill rod are too low, so that the working time gap of the push bench is too long, and the construction efficiency of the push bench is seriously reduced.
