Description

Big capacity rainwater is collected the filtration storage facility automatically

Technical field

The utility model relates to building field, and particularly a kind of big capacity rainwater is collected the filtration storage facility automatically.

Background technology

Because the underground space in city is limited, it is little that traditional subsurface stormwater is filtered the storage system capacity, when running into the weather of dashing forward following torrential rain or raining heavily continuously, traditional subsurface stormwater is filtered storage system can't hold a large amount of rainwater of storage, causes a large amount of rainwater to discharge nowhere.

Summary of the invention

In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of big capacity rainwater to collect the filtration storage facility automatically, it can be under the limited situation of urban underground space, utilize the external wall structure of building basement and the space between the basement space enclosing structure, what form the above scale of kiloton neither takies ground space, the big capacity subsurface stormwater that does not influence landscape effect is again filtered storage space, a large amount of rainwater automatic fitration is collected, not only substitute tap water as the part living water use, reach the conserve water resource, effectively reduce the purpose of municipal water supply pressure, and solved the problem of a large amount of storm-water drainages.

The purpose of this utility model is achieved through the following technical solutions: a kind of big capacity rainwater is collected the filtration storage facility automatically, it is characterized in that: the basement enclosed structure that it comprises the external wall structure of being located at the building basement outside, build outside the external wall structure, be located in the drainage water storage layer between external wall structure and the basement enclosed structure and be located at captation in the building basement; Be filled with filtering material in the described drainage water storage layer, the top of drainage water storage layer is provided with and is used for making the permeable filtration separation layer that permeable filtration is isolated between drainage water storage layer and hemisphere, is provided with between drainage water storage layer and the captation to be used for making the water stream channel of the water of storage in the drainage water storage layer by captation.

Use big capacity rainwater described in the utility model to collect the filtration storage facility automatically, can will all collect in the drainage water storage floor from the rainwater of building peripheries such as roof, garden, lawn, floor file district and track, after drainage water storage layer filters, deliver to captation by water stream channel and collect, the water of collection need not to handle or promptly can be used as the undrinkable water water source after simple process.Use this water source,, can provide water, service rack water and greenbelt water between the industrial water, water for fire, sanitaryware water, bathing of job site at Construction stage.After engineering completed for use, this system can provide water for fire and greening water, also can be resident family two kinds of water sources of registering one's residence are provided, and substitutes tap water and solves living water uses such as sanitaryware water and slurry.

In addition, the utility model technique scheme has also been done following improvement:

In order further to enlarge the dmp filter water storage space and convenient the filtration collected rainwater, described captation is made of the sump that the sole plate part of building basement is recessed to form downwards; Described water stream channel comprise the drainage blanket between the stratum of being located at sole plate and sole plate below and be located at drainage blanket and sump between overflow ducts, the bottom of described drainage water storage layer is communicated with drainage blanket, is filled with filtering material in the drainage blanket; Height is lower than the layer heights of roofs of drainage blanket at the bottom of the hole of described sump.The rainwater that flows into drainage water storage layer after drainage blanket further filters, by the overflow of overflow ducts nature to sump.Drainage blanket also can filter the groundwater resources from the stratum and collect overflow to sump.

Flow into water in the sump in order to further facilitate timely collection, in the described building basement or building basement top is provided with reservoir, is provided with between described sump and the reservoir to be used for the water in the sump is taken out water plug toward reservoir.After having accumulated a certain amount of water in the sump, by water plug the water in the sump is extracted in the reservoir and collects.Water in the reservoir can or rely on manpower to be transported to using with drainage facility of building basement or its top or its outside by pumping conduit.

Described permeable filtration separation layer comprises surface layer dankly, filter pipe distribution layer and the geotechnological layer of cloth that is provided with from top to bottom.

Compared to prior art, the utlity model has following advantage:

(1) can be under the limited situation of urban underground space, utilize the external wall structure of building basement and the space between the basement space enclosing structure, form neither taking ground space, not influencing the big capacity subsurface stormwater filtration storage space of landscape effect again of the above scale of kiloton, a large amount of rainwater automatic fitration is collected, not only substitute tap water as the part living water use, reach the conserve water resource, effectively reduce the purpose of municipal water supply pressure, and solved the problem of a large amount of storm-water drainages.

(2) pass through drainage blanket, not only can make full use of the abundant groundwater resources of building foundation periphery, its automatic fitration is collected, substitute tap water as the part living water use, thereby reach the conserve water resource, effectively reduce the purpose of municipal water supply pressure, also can discharge or reduce the water buoyancy of underground water, reduce the infiltration probability of sole plate the sole plate generation of building basement.

(3) big capacity rainwater described in the utility model is collected automatically and is filtered storage facility and meet national energy-saving and emission-reduction policy, has good application value.
