The utility model has the following characteristics:

1) a non-traditional regulation and storage tank is formed by universal supporters and overhead stone. The universal support is used for erecting a hollow hard pavement site, so that the site has a certain storage volume, rainwater can be stored in situ under hard pavement, and surface runoff in a certain range in a paved impervious area and the periphery can be stored. The rainwater is regulated and stored in situ under stereoplasm is mated formation, avoids the engineering of building the cistern in the excavation of the periphery of field, reduces the engineering volume by a wide margin. The former hard site needs to enlarge the volume of the matched rainwater storage facility due to the higher runoff coefficient, and the hard site does not become an extra burden when the solution is adopted. Meanwhile, compared with the traditional paving cushion layer or brick pier support and the like, the process of utilizing the universal support to support the hollow stone has lower cost, and the construction period is only about one fourth of that of the brick pier support. Comprehensively considering, compared with the traditional water storage and storage tank building, the solution has obvious advantages in terms of construction period and construction cost. Has great application potential for improving the field design reappearance period and the rainwater collection and storage utilization rate.

2) And (5) optimizing the process. Rainwater collection, initial rainwater discarding, rainwater filtration, in-situ regulation and storage under stone paving and rainwater recycling.

3) The construction difficulty is reduced, the project amount is reduced, and the construction period is greatly shortened. The stone is paved and supported by using brick piers, the surface course is leveled, the pavement butt joint, the whole elevation and the flatness are controlled, the construction precision is challenged, the engineering quantity is large, the construction difficulty is high, and the construction period is long. The universal support is selected to support hollow stones, gaskets with different specifications can be selected for surface leveling, the seam remaining is controlled by an adjusting piece, the overall elevation and slope finding can be flexibly adjusted by the support, even if the stone specifications are not complete, the precision is still very high, the construction difficulty is low, and the construction period can be greatly shortened; the method avoids additional construction of a reservoir around the site, particularly avoids deep foundation pits, a large number of complicated processes such as earthwork, steel concrete masonry and the like, and saves space and cost.

4) The stability and the safety are strong, and the maintenance is convenient. The water storage part of the collecting and storing recycling system is arranged under the stone in an overhead mode through the universal support, the support is safe and excellent in stability due to the fact that materials of the support and the process of the support are mature, and the uncovered stone overhauling is more convenient and fast compared with overhauling of a traditional impounding reservoir. (meanwhile, the potential safety hazards such as insufficient pressure resistance of a PP module reservoir and deeper excavation in the construction of a reinforced concrete reservoir are avoided)

5) Energy saving, environmental protection and low cost. The water storage part has the largest volume in the rainwater collection, storage and recycling system, the supporter is used for making the stone material overhead to obtain a storage regulation space, the use of unrecoverable materials such as concrete, glass fiber reinforced plastics and the like is avoided, the whole rainwater collection, storage and recycling system is more energy-saving and environment-friendly, and the cost is greatly reduced.

The utility model discloses abandoned the peripheral conventional way of building the cistern in place, changed into and carried out the rainwater regulation in the normal position in place of mating formation in the stereoplasm, will regulate the pond setting below the stereoplasm is mated formation, save the engineering volume and save space again, save the expense of additionally building the cistern, can reduce the cost that the retrieval and utilization system was held to the rainwater collection by a wide margin from this, save space, simplify construction process and reduction of erection time.

The preferred and optional technical means disclosed in the present invention can be combined arbitrarily to form a plurality of different technical solutions, except for the specific description and the further limitation that one preferred or optional technical means is another technical means.
