Problems solved by technology

When the manhole covers of various facilities are damaged or stolen, the occurrence of safety accidents is greatly increased. In addition, the maintenance passages on the road connected to the pipe network also increase. It is easy to lose, causing casualties, even on roads with severe water accumulation, the air pressure in the pipeline will lift the manhole cover, causing the manhole cover to fall off, causing unnecessary casualties or property losses

Embodiment Construction

[0012] Combine below Figure 1-5 The present invention will be described in detail.

[0013] According to the embodiment of the present invention, the protection device for the municipal inspection shaft is used to cover the inspection shaft opening 90 in the road main body 9, and includes a connecting hole 88 provided on the road main body 9 and a connecting hole capable of being inserted into the connecting hole 88. The main frame 8 of the protective net, the middle of the top of the main frame 8 of the protective net is provided with a protective steel mesh, thus, when the main frame 8 of the protective net slides into the connecting hole 88, the mouth of the inspection well 90 is closed , when the protective net main frame 8 slides away from the connection hole 88, the inspection well mouth 90 allows downhole construction; wherein, the left side of the protective net main frame 8 is fixedly provided with a downwardly extending supporting sliding plate 83, so The end of th...

Abstract

Provided are a novel protection device of a municipal inspection shaft and an operation method of the novel protection device. The device is used for covering an inspection shaft opening (90) in a road body (9) and comprises a connecting hole (88) formed in the road body (9) and a protection net main frame (8) capable of being inserted into the connecting hole (88). A protection steel net (80) is arranged in the middle of the top of the protection net main frame (8). Thus, when the protection net main frame (8) slides into the connecting hole (88), the inspection shaft opening (90) is closed. When the protection net main frame (8) slides away from the connecting hole (88), the inspection shaft opening (90) allows construction in the shaft. The whole device is reliable in running, the safety of pedestrians and vehicles can be effectively guaranteed, and meanwhile constructors can descend the shaft for maintenance conveniently when underground construction needs to be maintained.

Description

technical field [0001] The invention relates to the municipal field, in particular to a protection device for a municipal inspection shaft and an operating method thereof. Background technique [0002] With the continuous development of the city, the pace of municipal construction has been accelerated, and various municipal facilities have also increased accordingly. Such as telecommunications pipeline facilities, gas pipeline facilities, water supply and drainage pipeline facilities, etc. When the manhole covers of various facilities are damaged or stolen, the occurrence of safety accidents is greatly increased. In addition, the maintenance passages on the road connected to the pipe network also increase. It is easy to lose, causing casualties, and even on roads with serious water accumulation, the air pressure in the pipeline will lift the manhole cover, causing the manhole cover to fall off, causing unnecessary casualties or property losses. Under such conditions, we in...
