Well lid

Abstract

The invention provides a well lid, and relates to the technical field of well lids. The well lid is characterized in that a round well is formed in the top of a base, a stop block is arranged on the side wall of the top of the round well, a well lid body is placed on the stop block in a supported mode, a limiting block is arranged on the side wall of the round well, a limiting groove matched with the limiting block is formed in the side wall of the well lid body, the limiting groove comprises a matching groove which is used for accommodating the limiting block and is opened towards the side wall of the round well and a leading-in groove which is used for leading in the limiting block, and the leading-in groove is in communication with one end of the matching groove. The well lid can be quickly disassembled, assembled and fixed, is convenient to operate, safer, more stable and convenient to maintain, has the function of jacking up the well lid after being disassembled, saves time and labor, and is flexible and practical.

Description

technical field [0001] The invention relates to the technical field of well covers, in particular to a well cover. Background technique [0002] Manhole covers are often used in road engineering to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. Lane et al. There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section, and the manhole cover is leading to underground facilities. The closure on the top of the entrance and exit, where public facilities such as tap water, telecommunications, electricity, gas, heat, fire protection and sanitation are installed, a manhole cover needs to be installed. Manhole covers can be divi...

AI Technical Summary

Problems solved by technology

[0003] At present, the manhole covers in many places are directly placed at the opening of the round well. Although this installation method is very convenient, it will lead to the stability of the manhole cover. , causing safety hazards

In some places, in order to ensure the stability of the connection between the manhole cover and the foundation, a safety structure for fixing the manhole cover is provided. However, this method will lead to a relatively tight connection between the manhole cover and the foundation. The connection structure with the foundation is relatively complicated, and it is very cumbersome to operate. It is not convenient for maintenance personnel to fix the manhole cover, and it is also not convenient for maintenance personnel to disassemble the manhole cover. It is also necessary to use special tools or special equipment to remove the well cover from the round wellhead, which is very troublesome
