Abstract
The application provides a sponge rainwater collecting system for project faces and builds, including the road bed, the top of road bed is by supreme metalling and the concrete layer that permeates water of being equipped with down, the top surface on metalling is equipped with the anti-penetration membrane, the concave mounting groove that forms of top surface on metalling, be equipped with the blind pipe in the mounting groove, the hole of permeating water has been seted up on the blind pipe, blind pipe and cistern intercommunication. Rainwater permeates into the blind pipe through the pervious concrete layer and is stored in the water storage tank through the blind pipe, so that the rainwater is prevented from being accumulated on the ground, and the purpose of collecting and recycling the rainwater is realized.
Description
Technical Field
The application relates to the technical field of building construction, in particular to a sponge rainwater collection system for project temporary construction.
Background
The construction is carried out in a rainy period, and the accumulated water on the road surface directly flows into a drainage system, so that the waste of water resources is caused and larger pressure is generated on the drainage system.

Use the technical scheme of this application, the rainwater is in the blind pipe through the concrete layer infiltration that permeates water to store in the cistern through the blind pipe, prevented that the rainwater from piling up on ground, realized collecting the purpose of recycling to the rainwater.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present application.
Detailed Description
As shown in fig. 1, the sponge rainwater collection system for project construction provided by the embodiment of the application comprises a roadbed 1, a gravel layer 2, a sand large-pore pervious concrete layer 4, a coarse-grain modified pervious asphalt concrete layer 5 and a medium-grain modified pervious black asphalt layer 6 are arranged above the roadbed 1 from bottom to top, an anti-penetration film 3 is arranged on the top surface of the gravel layer 2, a mounting groove 11 is formed in the top surface of the gravel layer 3 in a concave manner, a blind pipe 7 is arranged in the mounting groove 11, a pervious hole is formed in the blind pipe 7, and the blind pipe 7 is communicated with a reservoir.
In this embodiment, the rainwater sees through in proper order the modified black pitch layer 6 that permeates water of grain formula, the modified asphalt concrete layer 5 that permeates water of coarse grain formula and the big hole concrete layer 4 that permeates water of sand get into the blind pipe 7 to finally flow into in the cistern, prevent penetrating membrane 3 and be the PE membrane, can prevent effectively that the rainwater from permeating rubble layer 2 in, a plurality of mounting grooves 11 that set up on rubble layer 2 are convenient for the rainwater and collect and get into in the blind pipe 7.
Specifically, the compacted density of the roadbed 1 is more than or equal to 0.93.
Specifically, the geotextile is wound on the outer side of the blind pipe 7, so that the pressure resistance and the water collection performance of the blind pipe 7 are improved.
In this embodiment, be equipped with granite rimstone 8 in the both sides of the concrete layer that permeates water, prevent that membrane 3 is located granite rimstone 8's inboard, be equipped with concrete bedding 9 between granite rimstone 8 and the non-sand macroporous concrete layer 4 that permeates water, be equipped with asphalt mastic joint compound 10 in granite rimstone 8's inboard, asphalt mastic joint compound 10 is located the top of preventing membrane 3.
During the use, the rainwater sees through the black asphalt layer that permeates water of grain formula modification, the modified asphalt concrete layer that permeates water of coarse grain formula and the sand macropore concrete layer that permeates water in proper order and gets into in the blind pipe to finally flow into in the cistern, prevented that the rainwater from piling up on ground, realized collecting the purpose of recycling to the rainwater.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
