A road drainage and leak sealing device

Abstract

This utility model relates to the field of municipal engineering technology, specifically a road drainage leak-stopping device. The device includes an arc-shaped sealing plate located outside the leaking part of a pipe. The bottom of the arc-shaped sealing plate is concave, and a sealing pad is provided at the bottom of the arc-shaped sealing plate to seal the gap between the arc-shaped sealing plate and the pipe surface. Two arc-shaped partition plates are fixedly connected to the concave bottom of the arc-shaped sealing plate. The device uses a fixing mechanism to fix the arc-shaped sealing plate to the outside of the leaking part of the pipe, thus plugging the leak. The entire leak-stopping device does not need to surround the pipe; it can be fixed to one side, avoiding the pipe, and is suitable for plugging leaks in underground pipes during road drainage. Simultaneously, a vacuum is created inside the adsorption chamber on the inner side of the arc-shaped sealing plate using a vacuum pipe, allowing the arc-shaped sealing plate to be more firmly fixed to the pipe surface.
