Multifunctional dual-layer well lid device

Abstract

The invention belongs to a multifunctional dual-layer well lid device. The multifunctional dual-layer well lid device comprises a well wall, a lid base installed on the upper portion of the well wall, and annular filler arranged between the well wall and the lid base. A protruding edge is arranged on the inner side of the lid base, an inner tray is arranged on the upper portion of the protruding edge, and an outer cover plate is arranged on the top of the lid base. At least two positioning slots are formed in the upper portion of the protruding edge. The inner tray is of a basin-shaped structure, a plurality of holes are formed in the side walls of the inner tray, and a crossed framework reinforcing rib is arranged on the top of the inner tray. A plurality of holes are formed in the top of the outer cover plate, and a plurality of concentric rib plate rings are arranged on the inner surface of the outer cover plate. Positioning convex blocks matched with the vertical positioning slots are installed on the outer circumferential surface of the rib plate ring on the outer layer. The multifunctional dual-layer well lid device has the advantages that the situation that safety accidents are caused by an open inspection well after a well lid is damaged or gets lost can be effectively avoided, the clean and dry environment in the inspection well is maintained, and workers can enter the inspection well to perform maintenance conveniently; and a drainage well lid has the functions of allowing rainwater to pass through smoothly and reducing the possibility that sludge and impurities enter the well.

Description

Technical field [0001] The invention belongs to the technical field of municipal engineering supplies, and specifically relates to a double-layer multifunctional well cover device. Background technique [0002] In the construction of municipal engineering, most of the pipelines for gas, telecommunications, electricity, heat, and water supply are arranged underground. Construction and maintenance require that manholes be kept at regular intervals. The manhole cover is a closed device on the top of the entrance to the underground facility. Most of these manholes are located on the side of urban roads, and coupled with the original roadside drainage pipelines, a large number of manhole cover devices are basically arranged on existing urban roads. The manhole cover located on the road surface is easily damaged as passing vehicles, especially heavy and overloaded vehicles, are crushed; sometimes the manhole cover is stolen by criminals; the manhole cover is sometimes washed away by th...

AI Technical Summary

Problems solved by technology

In order to solve the pipeline blockage, the municipal company must arrange personnel to clean the pipeline after a certain period of time. Most of the branch drainage pipelines are closed and small in size. When cleaning, only the sludge at the lower part of the drain can be dug out. , the sludge far from the drain is almost impossible to remove

Removing sludge in a small space, the working environment is not good, time-consuming and laborious, and the effect is not ideal
