The related art provides a hydraulic push bench for construction engineering, which comprises an L-shaped supporting plate, wherein one side wall of the L-shaped supporting plate is fixedly connected with a plurality of protection springs; one end of each protection spring far away from the L-shaped supporting plate is fixedly connected with one side wall of the spring backup plate; the inner top end of one side of the L-shaped supporting plate far away from the spring backup plate is provided with a hydraulic push bench; the upper end and the lower end of one side of the hydraulic pipe pushing jack are fixedly connected with pipe pushing jack fixing plates; the four corners of the two push bench fixing plates are respectively inserted with a first bolt, the outer walls of the upper end and the lower end of one side of the hydraulic push bench far away from the push bench fixing plates are respectively sleeved and connected with the inner walls of the limiting rings, and one ends of the two limiting rings, which are close to the L-shaped supporting plates, are respectively fixedly connected with a supporting block; one ends of the two supporting blocks, which are far away from the limiting rings, are respectively fixedly connected with the supporting plate of the push bench; two four corners of one end, far away from the L-shaped supporting plate, of the supporting plate of the pipe jacking machine are respectively inserted with a second bolt;

The hydraulic pipe jacking machine for the building engineering is characterized in that the contact surface between the hydraulic pipe jacking machine and the ground and the contact surface between the hydraulic pipe jacking machine and the wall are increased through the L-shaped supporting plate and the spring backup plate, so that the force is conveniently applied to the pipeline, and the hydraulic pipe jacking machine is matched with the supporting plate of the pipe jacking machine through the limiting ring, the supporting block and the supporting plate of the hydraulic pipe jacking machine; the stability of the hydraulic pipe pushing jack is improved, the spring is arranged, so that the hydraulic pipe pushing jack can have a certain buffer force for the force applied to the pipeline in the pipe pushing operation, the damage to the pipeline caused by the larger force is avoided, and the hydraulic pipe pushing jack has good practicability;

However, the hydraulic push bench for construction engineering has some defects, for example, in the working of the hydraulic push bench, the reverse thrust generated by the working of the hydraulic push bench is buffered and damped only through the arranged springs, and other components are not arranged to limit the springs, but damping and deceleration are performed through the combined action of a plurality of springs, so that the range of the lateral damping of the springs is limited; meanwhile, once the acting direction of the hydraulic push bench is shifted, the reverse acting force generated by the push bench is likely to be stressed unevenly due to the reverse acting forces of the springs, so that the phenomenon of breakage caused by overlarge stress of the springs at the extrusion part occurs;
