Construction method of anti-falling net structure of inspection well cover for municipal road

Abstract

The invention discloses a construction method of an anti-falling net structure of an inspection well cover for a municipal road. The construction method includes the steps that (1) a buffer assembly is installed; (2) butt joint of anti-falling net plates is conducted; (3) an inner anti-falling plate is mounted; (4) a filter hopper is mounted; (5) drill holes are marked; (6) an anti-falling filtering structure is formed; and (7) construction is conducted in place in an inspection well. The construction method of the anti-falling net structure of the inspection well cover for the municipal road is simple in process, low in positioning assembly and operation difficulty, low in labor intensity, high in construction efficiency and short in construction period, the construction cost is effectively reduced, flexible adjustment can be achieved in the construction process, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of municipal road safety facilities, and in particular relates to a construction method of an inspection shaft cover anti-fall net structure for municipal roads. Background technique [0002] 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. Called the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. At night, in rainy days, etc., due to the dark sight, once the inspection well cover is lost or washed away, and there is no protective measure on the inspection well, it is very easy for pedestrians or objects to fall into the inspection well, which will cause pedestr...

AI Technical Summary

Problems solved by technology

At night, in rainy days, etc., due to the dark vision, once the inspection well cover is lost or washed away, and there is no protective measure on the inspection well, it is very easy for pedestrians or objects to fall into the inspection well, which will cause pedestrians to be injured or even life-threatening.

[0003] In the prior art, a safety anti-fall net is usually installed in the inspection shaft, which has a simple structure, but the protection form is single, the carrying capacity is limited, frequent maintenance is required, the practicability is poor, and the gap is large, and rubbish such as stones and sundries can easily pass through the anti-fall net. The gap between the nets will affect the environment of underground pipelines and increase the difficulty of cleaning
