Embodiment Construction
[0014] A kind of waterproof wash away anti-rollover anti-fracture manhole cover, such as figure 1 , figure 2 As shown: the feature is that there is a tail fin 2 under the well cover 1, and the well cover 1 and the tail fin 2 are integrally formed. When the water level in the well is higher than the ground and pressure is generated on the well cover 1, the well cover 1 and the tail fin 2 are lifted by the water together, even if the water Discharge without being washed away by water, such as image 3 ; Because the empennage 2 is high, it is difficult for the manhole cover 1 to turn over;

Main urban drainage pipelines are usually laid in deeper positions under roads, inspection manholes are needed to be arranged in positions of corners, offshoots and falls and the like of the drainage pipelines so as to facilitate inspecting, cleaning up and dredging drainage pipelines, so far, manhole lids of the inspection manholes are cake-shaped in design, and the manhole lids have the disadvantages of proneness to being washed away, rolled over and broken. The invention provides an anti-washing-away, anti-rollover and anti-breakage manhole lid which can effectively overcome the defect that the manhole lids are prone to being washed away, rolled over and broken. The anti-washing-away, anti-rollover and anti-breakage manhole lid is characterized in that tail units are arranged under the manhole lid and integrated with the same; when water level inside a manhole is above ground level and produces pressure against the manhole lid, the manhole lid and the tail units are jacked up by the water, and the manhole lid cannot be washed away even the water drains out of a road surface; the manhole lid is hard to roll over since the tail units are high; the tail units have a function of reinforcing ribs so that the manhole lid is less prone to breakage.
Description
technical field [0001] The invention relates to a manhole cover, in particular to a water-proof, wash-away, rollover and breakage-proof manhole cover. Background technique [0002] The main road of urban drainage pipes is often laid deep under the road. In order to facilitate the inspection and cleaning of the drainage pipes, it is necessary to install inspection wells at the turns, branches, drops, etc. of the drainage pipes. It is easy to be washed away by water, easy to roll over, and easy to break. When a manhole cover on a street is washed away by water, passing citizens will be in danger. At around 9:00 p.m. on March 22, 2013, on a rainy night, the Chihuang Road in Tujiachong, Changsha, Hunan was covered with ocean. A 21-year-old girl accidentally fell into an uncovered inspection well and was swept away by the rapids of the sewer; on the evening of June 9, 2013, Guangxi A woman in Nanning also accidentally fell into an uncovered inspection well and was swept away by...
