Embodiment
With reference to embodiment, the utility model will be further described.
A kind of infiltration type storm detention tank of the present utility model is main by coarse sands layer 1, geotextiles 2, metalling 3, impervious barrier
4th, pond body 5, rainwater water inlet pipe 6, terrace layer 7, rainwater outlet pipe 8, cover plate 51, water seepage hole 52, cleaning cover plate 53 are constituted.
As shown in figure 1, a kind of infiltration type storm detention tank of the present utility model, including pond body, pond body upper end is provided with lid
Plate, the pond body surrounding pond body wall and bottom are provided with equally distributed water seepage hole；The pond body one side sets rain to enter
Water pipe, it is metalling that the pond body opposite side, which is set below rain outlet pipe, the pond body, and the metalling surrounding is provided with
Geotextiles, the lower section of metalling is coarse sands layer, and the top of metalling is impervious barrier, and the top of impervious barrier is terrace layer, and rainwater enters
It is internal that water pipe and rainwater outlet pipe are arranged on terrace layer.
The aperture of the water seepage hole 52 is 3-5em, and the gross area of perforate is surrounding pond body wall and the 1%- of bottom area
1.5%.
The side of the pond body 5 is provided with cat ladder.
Cleaning cover plate 53 is provided with the cover plate 51, cleaning cover plate 53 is arranged on the surface of pond body 5.
The left end of the rainwater water inlet pipe 6 is provided with stainless steel filtering net, the upper end of stainless steel filtering net and cleaning cover plate
53 positions are corresponding.
The bottom of the pond body 5 is provided with pile foundation.
In a kind of infiltration type storm detention tank of the present utility model, the top side of pond body 5 sets water inlet pipe, and opposite side sets out water
Pipe, water inlet pipe is slightly above outlet pipe, and pond body bottom and bottom are aperture area, and aperture area is fully embedded metalling.Aperture 5cm is left
The right side, percent opening 1%-1.5%.Cat ladder is set inside pond body, it is convenient that periodically pond is cleared up.
In order to prevent that pond body 5 is settled or offset caused by seepage flow, using piling strtucture, specific pile foundation form and number
Depending on pond body size.
Pond body 5 is seated on the bed course being made up of metalling 3 and coarse sands layer 1, between metalling 3 and coarse sands layer 1, rubble
Outside layer 3 and box cut between soil, geotextiles are set between metalling 3 and impervious barrier, and between metalling 3 and pond body 5.
Each layer band is followed successively by from bottom to top：Coarse sands layer-geotextiles-metalling-geotextiles-impervious barrier-back fill course.
As shown in Fig. 2 pond body volume is determined：In existing engineering, the volume of the rainfall regulative pool without seepage flow function is by adjusting
The difference for saving pond upstream and downstream flow determines that the utility model can also refer to such a method and be calculated pool volume is adjusted.Pass through
Regulating reservoir upstream flowrate and downstream flow and the difference of seepage flow flow are tried to achieve to the integration of time, expression is as follows：
In formula：V--- regulating reservoir volumes
Q is upper --- regulating reservoir upstream flowrate
Under Q --- regulating reservoir downstream flow
Q oozes --- regulating reservoir seepage flow flow
T--- rainfall durations
T--- calculates the rain time of rainfall
Specific calculation procedure is as follows：
Determine the deprivation coefficient of upstream and downstream, i.e. the ratio between upstream and downstream flow；When calculating different according to storm runoff rational formula
Section rainfall, obtains dropdown curve；The percolation flow velocity of different periods is tried to achieve according to Darcy's law, and then tries to achieve seepage discharge, is drawn
Go out percolation curve；By both curve combinings, the ultimate range in this two curve vertical direction, as pond body volume are found out.
As can be seen here, traditional storm detention tank without infiltration function is one kind of the storm detention tank with infiltration function
In the case that special circumstances, i.e. infiltration capacity are 0.So by Fig. 2 it can be found that the volume of the storm detention tank with seepage flow function exists
It is smaller than storm detention tank without seepage flow function under square one.Specific seepage calculation, can use Finite Element, pass through
Simulated rainfall course, is specifically calculated.Now estimated with open channel seepage flow, from the point of view of the empirical equation of open channel seepage flow,
Pool volume of the present utility model of regulating and storing can be than existing reduction by 20% or so.
A kind of infiltration type storm detention tank of the present utility model, it is practical, can regulate and store crest discharge while, can make
Part rainwater permeates the ground.The volume in pond can be greatly reduced, earthwork excavated volume is reduced, reduce the parameter of water pump, work is reduced
Journey cost.It is additionally, since volume reduction so that it, which takes up an area, reduces, and plant area space can preferably be made full use of.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
