Problems solved by technology

[0002] The current inspection well mouth has no other protective facilities except the inspection well cover. When the inspection well cover is lost, damaged, aged and broken, people will easily fall into the inspection well without paying attention, causing personal injury. Cracks occur, and the broken pieces fall into the sewer, causing road safety hazards and causing blockage of the sewer

Abstract

The invention discloses a horizontal protective net of a drain well cover. The protective net comprises a net body, wherein a plurality of net holes (2) are distributed on the net body (1); the circumference of the net body (1) is distributed with an outer rim (3); and a plurality of connecting holes (4) are distributed on the outer rim (3). The protective net not only has high strength and strongcorrosion resistance, but also is tightly connected with the mouth of a drain well so as to effectively prevent from falling off, improve the protective safety and be used for preventing fragments ofthe inspection well cover from falling into sewers.

Description

technical field [0001] The invention relates to a horizontal protection net for a manhole cover. Background technique [0002] The current inspection well mouth has no other protective facilities except the inspection well cover. When the inspection well cover is lost, damaged, aged and broken, people will easily fall into the inspection well without paying attention, causing personal injury. Breakage occurs, and the broken fragments fall into the sewer, causing road safety hazards and causing blockage of the sewer. Contents of the invention [0003] The invention provides a horizontal protective net for the inspection well cover, which not only has high strength and strong corrosion resistance, but also is closely connected with the inspection well mouth, effectively prevents falling off, improves the safety of protection, and can be used to prevent the inspection well cover from Debris fell in the sewers. [0004] The present invention adopts the following technical so...
