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, including a connecting hole 88 provided on the road main body 9 and a connecting hole 88 capable of being inserted into the connecting shaft. The protective net main frame 8 of the hole 88 is provided with a protective steel net 80 in the middle of the top of the protective net main frame 8. Thus, when the protective net main frame 8 slides into the connecting hole 88, the inspection well mouth 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 protective net main frame 8 is fixedly provided with a supporting sliding plate 83 extending downward on the left side The end of the supporting slidi...

Abstract

Provided are a protection device for a municipal inspection shaft and an operation method of the 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...
