Multi-functional multi-component composite inspection cover well

Abstract

The invention provides a multi-functional multi-component composite inspection cover well. The well comprises a well lid and a wellbore which are matched with each other, wherein the well lid is formed by performing rubber coating and rolling on an annular or spiral framework, the wellbore is composed by at least two sections of telescopic cylinders with internal and external threads, wherein, thetwo sections of telescopic cylinders are connected in a sleeving mode, a locking mechanism is arranged at the joint of the well lid and the wellbore, and an anti-falling mechanism is arranged in thewellbore. According to the well, the well lid and the wellbore are made of novel materials, light in weight, high in strength, acid-resistant, alkali-resistant and long in service life.

Description

technical field [0001] The invention relates to the field of inspection wells, in particular to a multifunctional multi-component composite inspection well cover. Background technique [0002] The inspection well is used in the residential area of ​​the building community, public building area, factory area, etc. The outer diameter of the buried plastic drainage pipe is not greater than 800mm, and the buried depth is not greater than 6m. It is generally located at the intersection, turning, pipe diameter or slope of the drainage pipe. A well-like structure made of integral injection molding of plastic or bricks for the convenience of regular inspection, cleaning and dredging, or inspection of downhole operations. Most of the existing manhole covers are made of concrete or cast iron. The weight of the concrete inspection manhole cover is 70 to 90 kg. It is difficult to open the manhole cover.

AI Technical Summary

Problems solved by technology

Most of the existing manhole covers are made of concrete or cast iron. The weight of the concrete inspection manhole cover is 70 to 90 kg. It is difficult to open the manhole cover. Cast iron manhole covers make a lot of noise when vehicles are rolled over, especially at night, which deeply affects the residents facing the street. Moreover, cast iron manhole covers have poor toughness, are easy to rust, and are often stolen. Once it is stolen, it will cause vehicle accidents and personal injuries if it is not replenished in time
