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 the depletion of groundwater in the deep underground
[0003] Therefore, under the influence of the impermeable surface in the city, the moisture contained in the atmosphere and the soil layer cannot carry out the natural exchange cycle, which will cause the air in the city to be extremely humid or extremely dry for a long time, and the moisture in the soil under the ground will continue to dry up For a long time, the city's climate was so harsh that it was difficult to improve, destroying the urban ecological environment, and making it impossible for human beings to live a healthy life

Embodiment 1

[0021] Such as figure 1 As shown, the eco-type permeable stratum structure includes an aquifer, a permeable layer and a surface layer that are tiled sequentially from bottom to top.

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

Embodiment 2

[0025] Such as figure 2 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that: the reservoir 1 is reserved at the underground soil layer 10, and the upper side of the underground soil layer 10 is formed by using construction waste. Carry out filling pressure and leveling, thereby formed pond slag backfill layer 11, the upper side of pond slag backfill layer 11 lays the relatively cheap waterproof geotextile layer 12, and the upper side of waterproof geotextile layer 12 is poured greater than 150mm thick permeable concrete infiltration Layer 7 (strength ≥ C20), the upper side of the permeable concrete permeable layer 7 is laid closely 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 connecting the water storage tank 1 and the permeable concrete permeable layer 7 is provided, and a centr...

Embodiment 3

[0027] Such as image 3 As shown, the structure and principle of this embodiment are basically the same as that of Embodiment 1 and Embodiment 2. The difference is that sand and gravel are laid on the upper side of the underground soil layer 10 for backfill compaction and leveling, and the sand thus formed Stone water storage layer 13, there are appropriate gaps in the particle gradation in this sandstone water storage layer 13, which is conducive to rainwater infiltration on the one hand, and also can store rainwater that has no time to infiltrate on the other hand. The upper side of the sand and gravel water storage layer 13 is closely pasted with a permeable concrete permeable layer 7 (strength ≥ C20) thicker than 150mm, and the upper side of the permeable concrete permeable layer 7 is closely pasted with a 30-50mm thick paving layer 8, and finally the The ecological pavement brick layer 9 is pasted horizontally 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...
