Waterproof and leakproof auxiliary laying equipment for cable pipe trench

The invention belongs to the technical field of cable laying, and particularly relates to waterproof and leakproof auxiliary laying equipment for a cable pipe trench. The equipment comprises a guide wheel and a cable penetrating pipe. A guide mechanism is fixed to a cable through three pressing mechanisms which are evenly distributed in the circumferential direction. When a cable is input, the cable drives the guide mechanism to slide along a cable penetrating pipe through the pressing mechanism, and the penetrating resistance of the cable is reduced through rolling of the supporting wheel in a supporting mechanism in the guide mechanism and the cable penetrating pipe. When the guide mechanism needs to be taken out, a sliding ring is pulled to slide, the sliding ring pulls a swing rod to swing through a pull rope, the swing rod swings to enable the arc face of a protruding block to make contact with an installation sliding rod, and the distance between the arc face area of the protruding block and a hinge sha
