The beneficial effects of the invention are as follows：1. compared with traditional osmosis type inlet for stom water, traditional osmosis type inlet for stom water bottom is open-celled structure, therefore traditional osmosis type inlet for stom water bottom can not carry out stiffening basic ground with materials such as concrete, simultaneously when level of ground water is higher, easily fine grained earth material is brought into inlet for stom water again, causes subgrade soil to loosen and the problem of road sinks with inlet for stom water occurs.And the inlet for stom water of the present invention, rainwater-collecting just open caisson and the infiltration bottom not perforate of heavy mud, therefore stiffening basic ground can be carried out, while bottom also effectively assume responsibility for ground load, therefore it is not susceptible to pit shaft sedimentation.
2. compared with traditional osmosis type inlet for stom water, traditional osmosis type inlet for stom water side wall is provided with permeability hole, easily fine grained earth material is brought into inlet for stom water in the presence of underground water side pressure, again because rainwater is without just heavy processing, the materials such as silt particle and leaf in rainwater also will easily permeate hole plug, so as to cause being greatly reduced for permeance property.And the inlet for stom water of the present invention, there is provided open caisson at the beginning of rainwater-collecting, just there is provided the active catch mud swash plate of stainless steel again inside the stainless steel pail in open caisson for rainwater-collecting, rainwater enters along active catch mud swash plate to bucket underflow, and form whirlpool in active catch mud swash plate bottom, silt particle is stopped by active catch mud swash plate, it is not easy communicating pipe of rising and flow into, therefore the impurity such as most silt particles and leaf is deposited on rainwater-collecting just in open caisson, into heavy mud infiltration well rain and impurity it is more traditional be directly entered being greatly reduced for inlet for stom water.Inlet for stom water of the present invention simultaneously, realize rainwater to periphery soil body penetration by setting osmos tube in heavy mud infiltration well, permeability hole is not opened directly in well side wall, and permeate bottom of the tube and be bent downwardly, utilize the effect of gravity, fine grained in the soil body is not easily accessed heavy mud infiltration well, therefore greatly reduces the blocked possibility of a whole set of inlet for stom water.
3. compared with traditional osmosis type inlet for stom water, traditional osmosis type inlet for stom water depth is generally less than and is equal to 1000mm, therefore inlet for stom water rainwater delivery pipe ttom of pipe is often smaller to the discrepancy in elevation at permeability hole, and the osmotic pressure of rainwater to the soil body is also smaller, and penetrating power is not strong.And inlet for stom water of the present invention, heavy mud infiltration well depth reaches 2000mm, therefore the well kick pipe ttom of pipe to osmos tube delivery port the discrepancy in elevation up to more than 1200mm, osmotic pressure greatly increases, penetrating power also greatly increases compared with traditional penetration type inlet for stom water, simultaneously because osmotic pressure is big, when in the initial stage of that level of ground water is not high for rainfall, a small amount of fine grained earth material of osmos tube water outlet mud can push to soil body distal end with rainwater, so as to further improve penetrating power.
4. compared with traditional osmosis type inlet for stom water, rainwater delivery pipe and the permeability hole discrepancy in elevation in traditional osmosis type inlet for stom water is minimum, again because permeability hole penetrating power is not high, therefore the rainwater overwhelming majority still drains into rainwater inspection well by rainwater delivery pipe, and cocurrent enters road rain water supervisor.And inlet for stom water of the present invention, the ttom of pipe of overflow pipe is with the difference in height of osmos tube delivery port up to more than 1200mm, again because osmos tube delivery port penetrating power is far above traditional penetration type inlet for stom water, therefore osmos tube can effectively share amount of rainfall, so that the amount of rainfall into overflow pipe is greatly reduced compared with the amount of rainfall of traditional penetration type inlet for stom water, to mitigate the discharge pressure of road rain water supervisor.
5. compared with traditional osmosis type inlet for stom water, traditional osmosis type inlet for stom water is due to can not effectively remove silt particle, therefore the rainwater sediment contamination content for entering rainwater delivery pipe is very high, afterwards in Reconstruction of City Road, rainwater cannot directly access road rain water inspection shaft, need to first carry out heavy mud processing.And inlet for stom water of the present invention, the rainwater in overflow pipe can be directly accessed road rain water inspection shaft by secondary heavy mud processing.
6. the material that technical solution of the present invention uses is finished-product material on current market in addition to stainless steel pail, installation is simple, technology maturation, the overflow pipe absolute altitude being generally less than due to existing road inlet for stom water delivery pipe absolute altitude in technical solution of the present invention, the permeability that technical solution of the present invention can be applied to existing road inlet for stom water well is transformed, and has good social value.
