Description
Technical field
The utility model relates to rain penetration technical field, more particularly, relates to a kind of municipal rain penetration device.
Background technology
Existing infiltration technology is mainly fixed against lays ecological sand base water-permeable brick, its action principle is by the high osmosis of water-permeable brick, rainwater to be permeated the ground, to reach recharge of groundwater, slow down the object of city flood, but along with the increase of service life, its permeance property reduces gradually, when heavy rain comes, osmotic effect does not reach designing requirement, most of rainwater enters municipal Storm Sewer Network, but alleviate at present the limited in one's ability of municipal drainage pressure, therefore need its structure study further and improve.
Utility model content
The purpose of this utility model is the problem of mentioning in above-mentioned background technology in order to solve, and a kind of municipal rain penetration device is provided, and it has improved the infiltration capacity of rainwater, has alleviated city flood, has improved service life, and osmotic effect improves greatly.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of municipal rain penetration device, comprise municipal inlet for stom water, rainwater-collecting module, be located at the layer of gravel of described rainwater-collecting module surrounding and bottom, and municipal drain, described rainwater-collecting module top is provided with waterproofing geomembrane, described rainwater-collecting module surrounding and bottom are surrounded by permeable geotextiles, described rainwater-collecting module is communicated with by module water inlet pipe with described municipal inlet for stom water, described municipal drain is communicated with by outlet pipe with described municipal inlet for stom water, described module water inlet pipe and described municipal inlet for stom water junction are provided with trash rack, the described layer of gravel that is positioned at bottom is laid with some soakaway trenchs, described rainwater-collecting module is connected with high pressure backwash pipeline, described high pressure backwash pipeline end is provided with high-pressure nozzle.
Further, the position that described outlet pipe is positioned at described municipal inlet for stom water is positioned at the position of described municipal inlet for stom water higher than described module water inlet pipe.
Further, described some soakaway trenchs are uniformly distributed.
Compared with prior art, the beneficial effects of the utility model are as follows: the municipal rain penetration device that the utility model provides, and it has improved the infiltration capacity of rainwater, has alleviated city flood, has improved service life, and osmotic effect improves greatly.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-rainwater-collecting module, 2-layer of gravel, 3-municipal administration inlet for stom water, 4-trash rack, 5-module water inlet pipe, 6-outlet pipe, 7-waterproofing geomembrane, the permeable geotextiles of 8-, 9-municipal drain, 10-high pressure backwash pipeline, 11-soakaway trench.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Known with reference to Fig. 1, a kind of municipal rain penetration device, comprise municipal inlet for stom water 3, rainwater-collecting module 1, be located at the layer of gravel 2 of rainwater-collecting module 1 surrounding and bottom, and municipal drain 9, rainwater-collecting module 1 top is provided with waterproofing geomembrane 7, rainwater-collecting module 1 surrounding and bottom are surrounded by permeable geotextiles 8, rainwater-collecting module 1 is communicated with by module water inlet pipe 5 with municipal inlet for stom water 3, municipal drain 9 is communicated with by outlet pipe 6 with municipal inlet for stom water 3, the position that outlet pipe 6 is positioned at municipal inlet for stom water 3 is positioned at the position of municipal inlet for stom water 3 higher than module water inlet pipe 5, module water inlet pipe 5 is provided with trash rack 4 with municipal inlet for stom water 3 junctions, the layer of gravel 2 that is positioned at bottom is laid with some equally distributed soakaway trenchs 11, rainwater-collecting module 1 is connected with high pressure backwash pipeline 10, high pressure backwash pipeline 10 ends are provided with high-pressure nozzle.
In the present embodiment, rainwater-collecting module 1 is along urban road both sides greenbelt or nonmotorized vehicle lane provided underground, module pond body uses permeable geotextiles 8 to wrap up, waterproofing geomembrane 7 is laid at top, earthing on it, gravel is laid in surrounding and bottom, as bed course and surrounding filler, both there is higher water permeability, prevented that mud from entering body inside, module pond simultaneously; Meanwhile, bottom layer of gravel is laid some soakaway trench 11(blind pipes) increase infiltration speed.
In the present embodiment, rainwater is flowed in rainwater-collecting module 1 and is carried out short-term storage by municipal inlet for stom water 3, and it is trash rack 4 that water inlet adds filtering grid, ensures that large-scale floating thing can not enter module pond, in order to ensure the basic water quality condition in module pond.
