Description
Technical field
The utility model relates to a kind of inspection well cover, is particularly useful for the inspection well cover external member that avenue uses, and belongs to urban infrastructure field.
Background technology
Inspection well cover is requisite urban operating mechanism on urban road, and the structure of existing inspection well cover does not have basic theftproof performance, therefore the stolen phenomenon of inspection well cover occurs often at present, because the stolen event of inspection well cover mostly occurred at night, in addition night is rather dark, observation is difficult, and the inspection shaft of disappearance well lid is larger to the threat of passerby and vehicle. In addition, the general compressive property of existing inspection well cover is poor, and the slag-soil truck of passing overload at night is easy to inspection well cover to damage by pressure. If disappearance, damaged inspection well cover are processed replacing not in time, be easy to cause danger, once and there is the damage of casualties, vehicle, it is difficult often that relevant department deals with on attribution of liability, compensation issue, caused very large burden to country and society.
In addition, national each big city waterlogging phenomenon happens occasionally in recent years. Generally speaking, under field conditions (factors), heavy rain drops on ground and progressively converges need a process in river. But because avenue adopts pitch or asphalt surface more, lost water seepage function, rainwater is more flows to rapidly river course by drainage system quickly. River course cannot hold so many water at short notice, so flood backflush has all appearred in a lot of place.
Pour in down a chimney the flood in the city of going down town, can make the pressure of the water in sewer pipe increase. The pressure of the water of the sewer pipe in low-lying location, city also can be very large simultaneously. The situation generation of well lid is knocked over, washed to the flood that so often can see the pressure increase of urban sewage pipeline. After existing inspection well cover is backed down by flood, not having other thing to be fixed in original position, drifts about to other place in the position that makes inspection well cover depart from inspection shaft. When flood washes from inspection well cover the position of inspection shaft, when surface gathered water, pedestrian is not easy to find that inspection well cover is rushed to open, if at this moment there is pedestrian, the inspection shaft of vehicle through not having inspection well cover to cover, easily causes casualty accident.
We also often can see in urban flood defence process, in order to prevent that inspection well cover from being backed down by the flood of inspection shaft inside, the situation of the sand hill that pressurizes on inspection well cover. But Manual pressurizing sand hill is time-consuming, effort.
CN102808425A has disclosed a kind of inspection well cover that has leg, and it comprises inspection well cover body, and the position of inspection well cover body periphery, in the one side towards inspection shaft, is connected with the leg of inspection well cover, and the material of the leg of inspection well cover is hard material. The length of the leg of inspection well cover is in the value range of 20 centimetres to 2 meters.
Although the inspection well cover that this invention can make the flood being increased by sewer pipe internal pressure back down does not drift about to surrounding, also can not knock over, only can rise to inspection shaft top. But the result of use of the inspection well cover in this invention can not be ensured, when the curtailment of the leg of described inspection well cover or while running into extraodinary flood, this inspection well cover still can directly be rushed, and the inspection well cover having rushed cause danger can on the contrary pedestrian and vehicle.
