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

[0013] Combine below Figure 1-5 The present invention will be described in detail.

[0014] The protective device for municipal manholes according to the embodiment of the present invention is used to cover the manhole mouth 90 in the road main body 9, and includes a connecting hole 88 provided on the road main body 9 and capable of being inserted into the connecting hole 88 The protective net main frame 8 in the middle of the protective net main frame 8 is provided with a protective steel net in the middle of the top, so that when the protective net main frame 8 slides into the connecting hole 88, the wellhead 90 is When the main frame 8 of the protective net slides away from the connecting hole 88, the wellhead 90 allows downhole construction. The connecting hole 88 is provided with a cushion 881 which is used to reduce the protection The impact force generated when the net main frame 8 slides into the connecting hole 88, thereby increasing the service life; wherein, the left...

Abstract

Provided are a protection device of 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 field of municipal administration, in particular to a protective device for a municipal manhole and an operation method thereof. Background technique [0002] With the continuous development of the city, the pace of municipal construction has been accelerating, and various municipal facilities have 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, it greatly increases the occurrence of safety accidents. In addition, the maintenance channels connected to the pipeline network on the road also increase, and the manhole covers of the maintenance ports do not have any protective measures. It is easy to lose and cause casualties. Even on roads with serious water accumulation, the air pressure in the pipeline will lift the manhole cover, causing the manhole cover to fall...
