Detailed Description
The present application is described in further detail below with reference to fig. 1.
The embodiment of the application discloses rainwater regulation system. Referring to fig. 1, a rainwater regulation system, its characterized in that: the water storage device comprises a filter layer 1, a water storage layer 2, a reservoir 3 and a concrete support layer 4 which are sequentially arranged from top to bottom.
Wherein, the concrete supporting layer 4 is used as the supporting benchmark, and the cistern 3 is opened on the concrete supporting layer 4 and is used for storing the water that the reservoir 2 permeates into. The water storage layer 2 is positioned on the concrete support layer 4 and is used for storing water permeated by the filter layer 1. The filter layer 1 is positioned on the ground surface and used for filtering solid impurities and permeating water;
in this embodiment, filter layer 1 comprises a plurality of stones, use the stone as filter layer 1, at first the cost of stone is lower, the stone accessible is to the cobblestone, gravel etc. sieves and obtains, compare the filter screen that makes in the metal and need not weld, processing, wait work, secondly it is more convenient to be under construction, support between filter screen and the drainage hole and the fixed all needs more construction work of filter screen, construction work through filling the stone is more convenient, place the stone in predetermined position can, go into the infiltration pipe down, bury the infiltration pipe with the stone can. Simultaneously, the filtration principle of filter stone lets water pass through the space between the filter stone, but can not let earth pass through, though a small amount of earth also can infiltrate the gap of filter stone, but because the clearance between the filter stone is not the hole of linear type, but rugged and sinuous space, earth is a direction of perpendicular to infiltration pipe to the atress direction of infiltration in the infiltration hole, so earth is difficult for also being difficult for blockking up the infiltration hole through filter layer 1.
In this embodiment, the water storage layer 2 is a wet soil layer. The water storage layer 2 is formed by filling wet soil, so that the water storage performance of the water storage layer 2 is guaranteed, meanwhile, gravity water and capillary water exist in the wet soil, the gravity water slowly flows downwards under the action of gravity and is stored in the water storage tank 3, the capillary water gradually rises along fine channels in the soil to form a capillary water hose with a certain height, and therefore the water supplement of cities is realized in sunny days and even dry seasons.
In order to prevent the filter stones in the filter layer 1 from being embedded into the wet soil layer, a separation net 21 is arranged between the water storage layer 2 and the filter layer 1.
In the same way, in order to prevent the wet soil from falling into the reservoir 3, the lower end of the water storage layer 2 is provided with a soil-separating and permeable layer 22. Make through separating in soil permeable stratum 22 that who can flow to cistern 3 from reservoir 2, wet soil can not drop to the cistern 3 in simultaneously to guarantee the normal work of cistern 3 and reservoir 2.
Specifically, the soil-separating and water-permeable layer 22 is a water-permeable geotextile, which utilizes the good air permeability and water permeability of the polyester staple fiber needle-punched geotextile to allow water flow to pass through, so as to effectively carry soil particles, fine sand, small stones and the like, thereby maintaining the stability of the water-soil engineering. Meanwhile, tensile strength and deformation resistance of the soil body are enhanced by utilizing the polyester staple fiber needle-punched geotextile, and stability of the whole structure is enhanced so as to improve the quality of the soil body. When the water flow is large, the permeable geotextile can effectively diffuse, transfer or decompose the concentrated stress, prevent the soil body from being damaged by the action of external force and protect the soil.
Because the water storage layer 2 is the wet soil layer, the wet soil layer needs to keep the inside to have the hole just can satisfy the water storage demand, consequently, concrete supporting layer 4 and separate and be provided with a plurality of support columns 23 between the net 21, support column 23 evenly interval distribution. Through setting up support column 23, support column 23 is used for supporting concrete supporting layer 4 and separates net 21 to make reservoir 2 be difficult for receiving the extrusion, thereby guarantee reservoir 2's stable work.
The reservoir 3 is communicated with a water outlet pipe 31, one end of the water outlet pipe 31 is positioned at the inner bottom wall of the reservoir 3, the water outlet end of the water outlet pipe 31 is communicated to the ground, and a water suction pump 32 can be arranged at the water outlet end of the water outlet pipe 31. When the water in the reservoir 3 needs to be used, the reservoir 3 is pumped through the water outlet pipe 31. The position of the water reservoir 3 can be set at a place where the water demand is large, such as an irrigation land and the like.
The implementation principle of the rainwater regulation and storage system in the embodiment of the application is as follows: solid impurities are filtered through the filter layer 1 and then flow to the water storage layer 2, the water storage layer 2 stores water and slowly permeates into the water storage tank 3, and the water in the water storage layer 2 evaporates in sunny days or even in arid seasons, so that the humidity of a city is kept. In other times of heavy rainfall, such as in rainy season, the water in the water reservoir 2 flows slowly into the reservoir 3, and is stored in the reservoir 3.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
