Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and in particular to a leakage-proof double-wall corrugated pipe drainage pipeline connection structure. Background Art

[0002] The anti-leakage double-wall corrugated pipe drainage pipe connection structure is a highly efficient anti-leakage design for underground drainage systems, mainly used to prevent water or sewage from leaking through the pipe connection parts.

[0003] According to a disclosed municipal water supply and drainage pipe docking device (publication number: CN 220561426 U), it includes a base, the exterior of which is fixedly connected to a first horizontal shell, the interior of which is slidably connected to a transverse plate; two double-walled corrugated pipes are supported by a placement seat, and an electric telescopic rod is extended and retracted to adjust the position of the arc clamping plate to align with the double-walled corrugated pipes. The rotation of the screw drives the longitudinal plate to slide, driving the electric telescopic rod to move. The movement of the electric telescopic rod drives the symmetrical arc clamping plates to move, which cooperate with the friction spring plate to form an open circular clamping structure to clamp and fix the double-walled corrugated pipes, thereby achieving the positioning of the double-walled corrugated pipes. During the docking process, the pulley rotates to cause the transverse plate to slide along the axis of the double-walled corrugated pipe, driving the movement of the arc clamping plate. The movement of the arc clamping plate drives the two docked double-walled corrugated pipes to automatically and accurately dock, thereby improving the efficiency and quality of municipal water supply and drainage pipe installation and docking;
