Problems solved by technology

First, because concrete is not water-permeable, the water on the surface of the brick body cannot penetrate into the soil below the concrete, so a large amount of water is prone to be generated on the surface of the ground. Flood disasters; on the other hand, studies have found that since rainwater cannot penetrate into the underground soil for a long time, it will cause the heat island effect in the city, destroy the climate within the urban agglomeration area, and indirectly affect human health; moreover, the underground soil has never had rainwater The infiltration will cause t

Example Embodiment

[0020] Example one

[0021] Such as figure 1 As shown, the ecological permeable stratum structure includes an aquifer, a permeable layer and a surface layer that are laid down in sequence from bottom to top.

[0022] There is a basement 3 under the stratum. The aquifer includes a structural layer 4 laid flat on top of the basement 3. The structural layer 4 is constructed with concrete materials to enhance its load-bearing strength. The structural layer 4 serves as a frame support for the load-bearing above the basement 3. . A waterproof layer 5 made of high-efficiency waterproof material is closely laid on the top of the structural layer 4, so that it can effectively prevent the moisture from continuing to seep down until it leaks from the top surface of the basement 3. In the basement 3 or on the same layer as the basement 3, there is a water storage tank 1. A drainage tube 2 and a centrifugal water pump connected to the opening of the drainage tube 2 are provided in the inner ca...

Example Embodiment

[0024] Example two

[0025] Such as figure 2 As shown, the structure and principle of this embodiment are basically the same as those of the first embodiment. The difference lies in: the reserved water storage tank 1 is selected at the underground soil layer 10, and the upper side of the underground soil layer 10 adopts pond residue composed of construction waste. After filling and leveling, a pond slag backfill layer 11 is formed. The upper side of the pond slag backfill layer 11 is laid with a relatively inexpensive waterproof geotextile layer 12, and the upper side of the waterproof geotextile layer 12 is poured with permeable concrete thicker than 150mm. Layer 7 (strength ≥ C20), the upper side of the permeable concrete layer 7 is covered with a 30-50mm thick paving layer 8, and finally the ecological pavement brick layer 9 is horizontally pasted on the upper side of the paving layer 8. A drainage pipe 2 is provided between the storage pool 1 and the permeable concrete perme...

Example Embodiment

[0026] Example three

[0027] Such as image 3 As shown, the structure and principle of this embodiment are basically the same as those of the first and second embodiments. The difference lies in: laying sand and gravel on the upper side of the underground soil layer 10 for backfilling compaction and leveling, and the resulting sand The stone water storage layer 13 has appropriate gaps in the particle gradation in the sand and stone water storage layer 13, which on the one hand facilitates the infiltration of rainwater, on the other hand, it can also store rainwater that is too late to seep. The upper side of the sand-gravel water storage layer 13 is closely pasted with a permeable concrete layer 7 (strength ≥C20) greater than 150mm thick, and a 30-50mm thick paving layer 8 is closely pasted on the upper side of the permeable concrete layer 7, and finally The ecological pavement brick layer 9 is horizontally pasted on the upper side of the paving layer 8.

Abstract

The invention provides an ecological permeable stratal configuration and belongs to the technical field of water collection and water intaking, and the ecological permeable stratal configuration can be used for solving the problems that because the existing urban surface soil layer is impermeable, moisture exchange and circulation can not be performed between the atmosphere and the soil layer, and after the situation lasts for a long time, the phenomena that the air in cities is extremely humid or extremely dry, and the water in soils below the surface soil layer continuously runs out are caused, thereby destroying urban ecological environments and affecting the human health, and the like. The ecological permeable stratal configuration comprises a surface layer and a water storing layer, wherein the surface layer is permeable and can cover the water storing layer, the water storing layer is arranged below the surface layer and can be used for storing water, and a permeation layer which can guide water flows to permeate downwards is arranged between the surface layer and the water storing layer in an appressed clamping mode. The ecological permeable stratal configuration has a good penetration function, and can achieve the rainwater drainage effect of a road surface; and meanwhile, when the outside is in hot dry climates, rainwater collected in the deep of the stratal configuration can be fed back to the air so as to achieve the effects of humidity adjustment and temperature reduction, thereby effectively solving two serious problems, namely, urban ponding and heat island effect.

Description

technical field [0001] The invention belongs to the technical field of water collection and water intake, and relates to a stratum structure, in particular to an ecological permeable stratum structure. Background technique [0002] At present, the laying of outdoor pavements in cities usually adopts pouring sufficient concrete to make a concrete layer, and then lays floor tiles to form a pavement after leveling its surface. First, because concrete is not water-permeable, the water on the surface of the brick body cannot penetrate into the soil below the concrete, so a large amount of water is prone to be generated on the surface of the ground. Flood disasters; on the other hand, studies have found that since rainwater cannot penetrate into the underground soil for a long time, it will cause the heat island effect in the city, destroy the climate within the urban agglomeration area, and indirectly affect human health; moreover, the underground soil has never had rainwater Th...
