Description
Technical field
The invention belongs to hydraulic engineering technical field, specifically a kind of urban underground space entrance has blocking excess water
The rain perforaled strainer of function.
Background technology
In recent years, as China's rapid economic development, Urbanization Construction are accelerated, the huge of precipitation runoff process is brought therewith
The problem of big variation, Urban Waterlogging scarce capacity, highlights, once meeting extra torrential rain, just waterlogging takes place frequently in city；In addition south in recent years
Each province rainstorm weather is frequently and abnormal rainfall is on the high side, seriously threatens life and property safety of people and urban underground space
Effective operation；The traditional method of blocking city excess water is exactly to block pouring into for rainwater with sandbag, plank, technical staff also into
It has gone various improvement, has such as been blocked using rubber bag water-filling, using various forms of component assemblies ..., but the surprise attack of heavy rain is often
Have little time to smoothly complete above-mentioned work, even midnight, day off heavy rain are attacked sometimes, are had little time establishment officer at all and are carried out flood control
Anti-blocking, people life property safety is seriously threatened, and whenever torrential rain bust, cell underground garage or ground always occur for China
The phenomenon that underground spaces such as lower room are submerged, causes a large amount of vehicle or important item to be flooded by rainwater, is brought greatly for people
Economic loss；Even if some cells can be urgent to dispose sandbag prevention waterlogging or using prevention waterlogging when rainwater increases to a certain extent
Fence etc. to prevent the underground space by water submerged, but these facilities arrange in the rain it is very inconvenient, if in advance arrangement again can hinder
The normal use of road, and after heavy rain, it is also necessary to artificial removal, it is time-consuming and laborious；Conventional method working efficiency is low, water blocking
Effect is poor, removes of high cost；Flush type anti-flood wall, the CN of 107476248 A floating ball swing rods of Chinese patent CN driving
The flush type anti-flood wall that 107653836 A lift the flush type anti-flood wall of push rod driving, 107476247 A pulleys of CN are drawn
Deng improving conventional method, operation principle is：It normally is being in hidden state without waterlogging period water fender, is not influencing to lead to
The normal use in road only has after a small amount of rainwater enters floor drain when waterlogging is formed, can make to fill water in floating ball slideway early period,
Under the buoyancy of floating ball, is pushed by straight-bar or lever agitates or rope draws around pulley, driving water fender is opened up upwards
Water blocking is opened, the case where suddenly raining cats and dogs cannot be coped with by solving conventional method；Above-mentioned patented technology reasonable idea, but the nothing in reality
Method is implemented, and such as regional in south China, annual rainfall is big and rain time is long, and rainfall is less than urban design flood control standard condition
Under, the surface gathered water less than urban design flood level belongs to normality, and vehicle more belongs to normally into the underground space in this case,
When vehicle enters the underground space, surface gathered water can be driven naturally and pour in the underground space, using above-mentioned patented technology, will result in
As long as the ponding that road surface occurs pours in the underground space by vehicle drive, " even if only a small amount of rainwater enters floor drain, floating ball can be made
Under buoyancy, is pushed by straight-bar or lever agitates or rope draws around pulley, driving water fender is unfolded to keep off upwards
Water " can thus form " overprotection " state, normally go on a journey state less than urban design flood level, people in surface gathered water
Under, water fender is but in lifting status, and traffic can not pass in and out the underground space, seriously affect people’s lives.
Invention content
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of discrepancy of urban underground space
Mouth has the rain perforaled strainer of blocking excess water function, by pedestal, slope, storage ramp, catchment tray, supporting block, drainage channel, side
