Ecological permeable stratal configuration

[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 cavity of the storage pool 1, and the lower end of the drainage tube 2 is open The port is connected to the inner cavity of the storage tank 1 through a centrifugal water pump, which extends upward until the upper end port reaches and communicates with the permeable layer laid on the upper side of the waterproof layer 5. The permeable layer includes the ceramsite permeable layer 6 directly laid flat on the upper side of the waterproof layer 5. The ceramsite permeable layer 6 has a large permeability, so it can accelerate the infiltration rate of water, and its thickness is greater than 100mm, and the upper end of the drainage tube 2 is open The port is connected to the bottom of the ceramsite permeable layer 6. The upper side of the ceramsite permeable layer 6 is poured with a permeable concrete permeable layer 7 (strength≥C20) thicker than 150mm. The surface layer laid on the upper side of the permeable layer includes the ecological pavement brick layer 9. First, the cement mung bean mortar with a ratio of 1:4 is laid on the upper side of the permeable concrete permeable layer 7 to a thickness of 30-50mm to form an ecological pavement for bonding The paving layer 8 of the brick layer 9, and then the ecological pavement brick layer 9 is horizontally and closely attached to the paving layer 8.

[0023] When it is in rainy weather, because there are a large number of connected pore structures between the surface layer and the permeable layer, rainwater is easy to seep from the surface layer to the bottom of the permeable layer, and is blocked by the waterproof layer 5 and stagnates above the waterproof layer 5. Then it flows into the drainage tube 2 until it is collected in the cavity of the storage tank 1. At this time, the rainwater seepage collection can reduce the road surface water and keep the road surface clean; in the case of rainy weather or high humidity, no humidity replenishment is required, so storage The rainwater will be kept in the storage tank 1 for a long time; when the outside climate becomes high and dry, the centrifugal water pump set in the storage tank 1 provides driving force, and the rainwater in the cavity is pumped out of the ground to spray the road and vegetation, thus achieving Feed back to the air to adjust the air humidity and lower the atmospheric temperature. This stratigraphic structure solves the two major problems of urban water accumulation and heat island effect.

[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 permeable layer 7 to communicate the two, and a centrifugal water pump connected to the drainage pipe 2 is also provided in the storage pool 1.

[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.

[0028] When it is raining, rainwater infiltrates from the ecological pavement brick layer 9 and the permeable concrete layer 7 to the sandstone water storage layer 13, and most of the rainwater is retained in the sandstone water storage layer 13; When it is at high temperature and dry, the retained rainwater is fed back to the outside air through natural evaporation, which can regulate the humidity and lower the temperature.
