Bury formula rainwater and collect and utilize system

Technical Field

The utility model relates to a construction technical field, concretely relates to bury formula rainwater and collect and utilize system.

Background

In China, water resources are in short supply, particularly in remote mountain areas, drinking water is in short supply in places with dispersed population, and when the traditional water resource development mode can not increase water resources any more, the rainwater is recycled to become an economical and practical water resource development mode. The rainwater is used as a high-quality fresh water resource in nature, and the rainwater is recycled, so that the remarkable water-saving effect is achieved, and the water resource crisis can be relieved.

At present, the mode of collecting rainwater as irrigation use has been widely popularized in arid regions of China, but the matched large-scale rainwater collecting device is often only suitable for farmland irrigation, and rainwater recycling equipment rarely exists in cities, so that the rainwater collecting efficiency and the collecting area are greatly reduced, and a related rainwater collecting device matched with urban buildings is continued.

Through published patent search, the following relevant documents were found:

improve water resource utilization's urban afforestation water structure (CN110526459A) discloses an improve water resource utilization's urban afforestation water structure, including setting up the water inlet in road low-lying department, the setting is at the greenbelt of road edge, still including setting up the sedimentation tank in the road below, ultraviolet sterilization pond, the chemical disinfection pond, the sedimentation tank is located under the water inlet, between sedimentation tank and the ultraviolet sterilization pond, all be connected through the water pump between ultraviolet sterilization pond and the chemical disinfection pond, subaerial charge door that sets up, the charge door passes through the filling tube and is connected to the chemical disinfection pond, the chemical disinfection pond still links to each other with the delivery pipe, set up the lifting pump in the delivery pipe, the delivery pipe includes kicking up section and horizontal segment, the horizontal segment is located the greenbelt top, a plurality of drip openings of evenly distributed on the horizontal segment, the drip opening is located the bottom surface of horizontal. The invention is used for solving the problem of large water consumption of the green belt for irrigation in the prior art and achieving the purpose of improving the saving and utilization rate of urban water resources.

Through analysis, the above-mentioned patent has great difference with this application on the lamellar structure that the rainwater was filtered, urban earth's surface supports and rainwater is collected, and the novelty of this application is not influenced to above-mentioned patent admittedly.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a bury formula rainwater and collect and utilize system, this system has effectively solved urban area's rainwater automatic collection problem, and the space height is intensive, low cost, and construction convenience does not destroy urban road surface and supports, does not influence urban resident trip.

A buried rainwater collecting and utilizing system is buried in a ground foundation pit below a building drainage vertical pipe, a concrete foundation layer is fixedly arranged at the bottom of the ground foundation pit, and a water storage unit is fixedly erected on the concrete foundation layer; the top of the water storage unit is paved with geotextile, the geotextile is filled with a coarse sand layer, and a permeable brick layer is paved on the coarse sand layer; a gravel area is laid on the coarse sand layer and is positioned right below the vertical drainage pipe; a water lifter is fixedly arranged in the water storage unit, and the water lifter upwards penetrates through the geotextile, the coarse sand layer and the permeable brick layer in sequence and extends upwards.

Moreover, the rubble district encloses the fender including the equal open-ended leak protection in top and bottom, and this leak protection encloses that fender bottom is fixed pegs graft on coarse sand layer upper portion, and the leak protection encloses to keep off the intussuseption and is equipped with the rubble.

And, the water storage unit includes PP module and waterproof membrane, wherein the bottom of PP module and all around all seal the cladding waterproof membrane.

The utility model has the advantages and the technical effect be:

the utility model discloses a bury formula rainwater and collect and utilize system, collect the rainwater that is discharged by the drainage riser through rubble district prefiltration and concentrate, then the rainwater is further filtered by coarse sand layer, prevent that dust and silt that mix in the rainwater from falling into the water storage unit, and then filter the coarse sand in the rainwater through geotechnological cloth, make the rainwater store up in the PP module through geotechnological cloth, PP module bottom and the waterproof membrane of cladding all around play the effect of preventing the loss of depositing water, concrete foundation layer provides the underground of whole bury formula rainwater collection and utilization system and supports finally; in addition, the stored water in the PP module is conveyed to the ground by the water lifter, the water scattered or leaked by the water lifter falls into the PP module again through the permeable brick layer, the coarse sand layer and the geotextile, and the permeable brick layer is paved on the urban ground, so that the traveling requirements of urban residents at the ground foundation pit position are not influenced.

The utility model discloses a bury formula rainwater and collect and utilize system has effectively solved urban area's rainwater automatic collection problem, and space height is intensive, low cost, and construction convenience does not destroy urban road surface and supports, does not influence city resident's trip, is a rainwater collection and utilization system who has higher creativity.
