detailed description

The present invention will be described in detail in conjunction with Fig. 1, 2 and 3. Several garden inspection wells 13 are arranged in the green land on the composite storage and drainage environment-friendly ground, and the roads on the composite storage and drainage environment-friendly surface are sequentially connected with permeable wells 13 from top to bottom. Brick layer 5, permeable paving layer 4, cast-in-place permeable layer 3, permeable base layer 2 and rammed soil layer 1, the permeable brick layer 5, permeable pavement layer 4, cast-in-place permeable layer 3, permeable base layer 2 and rammed soil Several road inspection wells 10 are arranged between the vertical sections of the layer 1, and the road inspection wells 10 are provided with inspection well top covers 6, drainage pipe 1 7 and drainage pipe 2 8 sequentially from top to bottom. One end of the pipe one 7 is evenly distributed on the well wall of the road inspection well 10, one end of the drain pipe one 7 is connected to a swivel elbow, the other end of the drain pipe one 7 is connected to the permeable base layer 2, and the drain pipe one 7 is connected to the water-permeable base layer 2. On the same horizontal plane, the vertical distance between the bottom of the drainage pipe 17 and the bottom of the permeable base 2 is 50 mm, and the garden inspection well 13 is provided with an inspection well top cover 6, an overflow pipe 12 and a water seepage pipe 11 sequentially from top to bottom. The outer surface of the seepage pipe 11 is provided with several small holes, the garden inspection well 13 and the road inspection well 10 are directly below the cushion 9, and the drainage pipe 2 8 and the overflow pipe 12 are connected to the municipal drainage pipe.

The cast-in-place permeable layer 3 adopts permeable concrete with a thickness of 100MM-200MM; the continuous porosity of the permeable concrete is 15%-25%; the vertical and horizontal temperature joint spacing of the permeable concrete is 4000MM-6000MM.

The permeable base 2 adopts a gravel layer with a thickness of 150MM-250MM; the porosity of the permeable base 2 is 20%-40%.

The gravel filter layer is paved around the seepage pipe 11, so as to prevent silt from blocking the tiny holes on the seepage pipe 11.

The cushion layer 9 is a cuboid formed by pouring C10 concrete.

One end of the drainage pipe 7 and the seepage pipe 11 connected to the permeable base layer 2 is provided with a mesh filter cover.

The upper surface of the manhole top cover 6 is evenly distributed with several water leakage holes.

The average water storage per unit area of the present invention is 0.09m ³ , which is converted into a precipitation of 90mm. According to the meteorological data, it can be seen that according to the 12h rainfall standard (mm), light rain<5 MM, moderate rain 5-14.9 MM, and heavy rain 15-29.9 MM , rainstorm 30-69.9 MM, heavy rainstorm 70-139.9 MM, extra-heavy rainstorm > 140 MM, therefore, without considering soil seepage and rainwater inflow into the drainage system, it is also possible to achieve 12 hours of rainstorm weather without water accumulation, according to 40% of the inflow drainage Considering that it is possible to achieve 12 hours of heavy rain without water accumulation on the surface.

When the present invention is applied on the ground of a car dealership, the permeable brick layer 5 and the permeable paving layer 4 are not laid; Permeable paving layer 4.

When in use, the user adjusts the angle between the swivel elbow and the drainpipe 7, thereby adjusting the water storage level in the permeable base 2. When it rains, the rainwater passes through the top cover of the inspection well 6, the permeable brick layer 5, and the permeable paving layer. 4 and the cast-in-place permeable layer 3 flow into the permeable base 2, and the excess rainwater is discharged into the municipal drainage pipe through the drain pipe 2 8 and the overflow pipe 12, while the water in the permeable base 2 and the garden inspection well 13 passes through the seepage pipe 11 to the ground When the weather stops raining, the water in the permeable base 2 evaporates into the air, which can adjust the temperature and humidity of the air and alleviate the urban heat island effect. Its porous structure also has the function of noise reduction and dust absorption.
