Embodiment 1

[0043] A sponge city pavement permeable pavement structure, such as Figure 1-6 As shown, it includes a covering layer 1, a crushed stone layer 2, a fine sand layer 3, a glass fiber layer 4, a fine filter layer 5, and an aquifer 6 arranged in sequence from top to bottom, and the aquifer 6 includes a reservoir 7. The partition plate 8 fixed on the inner wall of the reservoir 7 and the top plate 9 fixed on the top of the partition plate 8, the inner wall of the top plate 9 is provided with uniform permeable holes 10, and the inner wall of the partition plate 8 is provided with a water storage port 11, The cavity between the top plate 9 and the partition 8 of the reservoir 7 is filled with activated carbon particles; the covering layer 1 includes but not limited to hollow brick structure, permeable fiber asphalt concrete structure, permeable concrete structure, greening soil planting structure, Artificial turf structure; the fine filter layer 5 includes but not limited to PP cott...

Embodiment 2

[0048] A sponge city pavement permeable pavement structure, such as Figure 1-6 As shown, in order to solve the problem of energy saving; this embodiment makes the following improvements on the basis of Embodiment 1: the bottom of the partition 8 is provided with an energy recovery part 12, and the energy recovery part 12 includes The water storage pipe 24, the generator 18 and the turbine 22 fixed to the bottom of the partition plate 8 by bolts, the water inlet of the turbine 22 is connected to the water outlet of the water storage pipe 24, and the input shaft of the generator 18 is connected to the connecting shaft. 19 is connected to the output shaft of the turbine 22; by setting the generator 18 and the turbine 22, when the rainwater flows along the water storage pipe 24, it can drive the blades of the turbine 22 to rotate, thereby further converting the kinetic energy converted from the gravitational potential energy of the rainwater into mechanical energy , the mechanica...

Embodiment 3

[0054] A sponge city pavement permeable pavement structure, such as Image 6 As shown, in order to solve the pressure jump; this embodiment makes the following improvements on the basis of embodiment 1: the inner wall of the small diameter cylinder 29 is slidably connected with a sliding rod 32, and the outer wall of the sliding rod 32 is provided with a spring 2 35, The outer walls on both sides of the small-diameter cylinder 29 are respectively fixed with a limiting plate 31 and a supporting plate 2 34 by bolts, and the outer walls of the supporting plate 2 34 are rollingly connected with a piston 2 30 .

[0055] Since in embodiment 2, during the entire moving process of the conical plug 21, the force is linear, which results in that when the water level rises to the liquid level that just drives the conical plug 21 to move, the conical plug 21 21 will leak when it is opened, and the liquid level will drop after the leak, and the tapered plug 21 will reset again, which will ...

Abstract

The invention discloses a sponge city road surface permeation paving structure and a paving method thereof, and relates to the technical field of city road structures. In order to solve the problem of water storage, the structure comprises a covering layer, a gravel layer, a fine sand layer, a glass fiber layer, a refined filtration layer and a water storage layer which are sequentially arranged from top to bottom. The method comprises the steps that a water storage layer is partially installed on the bottommost layer, then a fine filtration layer and a glass fiber layer are gradually laid, a fine sand layer is laid, the fine sand layer with the height smaller than half of the designed height is laid firstly, then the fine sand layer is inserted into hollow steel pipes, the fine sand layer continues to be laid till the required height is reached, and a gravel layer is laid; the gravel layer is laid on the fine sand layer according to the design quantity, then a vibration motor is arranged on the top of the steel pipe, and the vibration motor compacts the whole gravel layer and the fine sand layer by layer through high-frequency vibration. When rainwater appears on the top of the covering layer, the rainwater can sequentially permeate into the gravel layer and the refined filtration layer and then enters the water storage layer to be stored, and the purpose of collecting and utilizing the rainwater is achieved.

Description

technical field [0001] The invention relates to the technical field of urban road structures, in particular to a sponge city pavement permeable pavement structure and a pavement method thereof. Background technique [0002] Since the roads in most cities are impermeable asphalt roads and concrete roads, the drainage of the roads is very poor. Basically, the drainage is carried out through the drainage ditches on both sides of the road, resulting in high drainage pressure of the drainage ditches, so that the drainage is not timely. , leading to water accumulation on the road, and in severe cases, it will also cause flooding and other situations. [0003] In order to solve the above problems, after searching, the patent of Chinese Patent Publication No. CN206127800U discloses a sponge city seepage road structure, including a permeable floor layer, a water-permeable road base, a graded filter layer, and a road bed. The graded filter layer is equipped with Several seepage pipes...
