FRP inspection shaft safety filter element

Abstract

The present invention provides an FRP inspection shaft safety filter element. The filter element comprises a top end, a bottom end and a side wall positioned between the top end and the bottom end; the top end is of an opening structure; the bottom end is of a sealed structure; the side wall is provided with filtering holes; sewage flows in from the opening structure and flows out from the filtering holes; the side wall is divided into an upper layer side wall, an intermediate layer side wall and a lower layer side wall from top to bottom; the upper layer side wall is provided with first filtering holes; the intermediate layer side wall is provided with second filtering holes; the lower layer side wall is provided with third filtering holes; and the first filtering holes and the second filtering holes are distributed in a staggered manner. According to the FRP inspection shaft safety filter element, the problems that bilge wells and sewers are easily blocked and difficult to clean, and cost is high are solved; and after the filter element is filled with sewage, municipal workers can clean and recycle the sewage as clean a dustbin, and municipal pipeline dredging cost and worker labor are reduced.

Description

technical field [0001] The invention relates to the field of inspection well safety protection, in particular to a glass steel inspection well safety filter element. Background technique [0002] The inspection well is a well used in the turning, branching, falling, etc. of the drainage pipe to facilitate inspection and dredging. There are many inspection wells on urban roads, and the rolling of passing vehicles often causes the manhole cover of the inspection well to rupture; meanwhile, in real life, the stolen thing of the inspection well cover often occurs. [0003] The traditional inspection well safety protection and filtration methods are inspection shaft cover protection and grille filtration. On the one hand, after the manhole cover is damaged or stolen, it will often bring great safety hazards to pedestrians and vehicles; on the other hand, the grille filter can only be used for preliminary filtering, and the sewage wells and sewers are still easy to block after fi...

AI Technical Summary

Problems solved by technology

The invention provides a safety filter element for glass fiber reinforced plastic inspection wells, which solves the problems of easy blockage of sewage wells and sewers, large cleaning projects and high costs, reduces the cost of municipal dredging pipelines and labor workload of workers, and improves the safety of life and property of personnel and vehicles
