Embodiment Construction
[0010] The bellows wall is recommended to be made of weather-resistant plastic material. The elastic steel wire is wrapped between the walls of the bellows. When a flood occurs, the manhole cover is pushed up by the high-pressure water flow, the bellows are stretched, the water flows out from the through hole of the bellows, and the water flow is depressurized. The corrugated pipe fixes the inspection well cover on the top of the inspection well, and at the same time warns pedestrians or vehicles to avoid. After the flood recedes, under the action of elastic force, the manhole cover resets automatically, or resets with manual assistance.

The invention relates to a corrugated pipe special for an inspection shaft cover. The corrugated pipe aims at solving the problem that the inspection shaft cover is washed away through flood. According to the scheme, through holes are formed in a pipe wall of the corrugated pipe; plane edges are arranged at the two ends of the corrugated pipe; through holes are formed in the edge of the corrugated pipe, and fixing screws penetrate the through holes; a spring is contained in a pipe body of the corrugated pipe; and light-reflection materials are contained on the outer side of the pipe wall of the corrugated pipe. When the flood occurs, the inspection shaft cover is ejected by high-pressure water flow, the corrugated pipe is pulled and lifted, and the water flow flows out from the through holes of the corrugated pipe. The corrugated pipe has the effects of warning pedestrian, preventing the pedestrians from falling into an inspection well and preventing the inspection shaft cover from being washed away at the same time. After the flood retreats, the inspection shaft cover automatically resets, or inspection shaft cover is reset under assistance of manual work.
Description
Technical field: [0001] The invention relates to a special corrugated pipe for manhole cover. Background technique: [0002] At present, the commonly used manhole cover has a round cake-shaped structure, generally does not have an automatic pressure relief function, and is easily washed away by floods. Pedestrians or vehicles are easily trapped in the inspection shaft. Similar accidents are commonly reported. At present, the commonly used remedial measures are: increase the anti-falling net in the manhole cover inside. Fall arrest nets cannot prevent manhole covers from being washed away. Invention content: [0003] The purpose of the invention is to solve the problem that the manhole cover is washed away by the water flow. [0004] The solution of the present invention: a special corrugated pipe for manhole cover, which is composed of a corrugated pipe body, and its characteristic is that the pipe wall of the corrugated pipe contains through holes. When the bellows i...
