Hydraulic control system of underground pipe network construction spiral pipe jacking machine

The utility model discloses a hydraulic control system of an underground pipe network construction spiral pipe push bench, which relates to the field of hydraulic equipment, and comprises an oil tank, a first pump source assembly and a second pump source assembly are respectively arranged on the side surface of the oil tank, and the first pump source assembly and the second pump source assembly work independently. The first pump source assembly and the second pump source assembly are independently controlled through the second control valve set and the first control valve set respectively. The two independent pump source assemblies are arranged, simultaneous work or independent work can be achieved, control is flexible, and the work efficiency is improved; the flow control valve group ensures that the speed is controllable when the hydraulic oil cylinder stretches out in the actual working condition, and the working efficiency is improved; the load control valve group realizes stable action of the hydraulic m
