Problems solved by technology

[0003] The purpose of the present invention is to address the above existing problems and provide a method for making the road surface have a strong ability to store rainwater and reduce rainwater loss. The method is simple to operate, ecological and environmentally friendly, and can significantly improve the water storage performance and pollutant purification of the road surface and surrounding soil It can moderately adjust the local climate, significantly alleviate the problems of urban "rainwater disease" and "heat island effect" and urban soil water shortage, and has significant economic and social benefits

Embodiment 1

[0030] A method to make the pavement have a strong ability to store rainwater and reduce rainwater loss is achieved through the combination of infiltration pipes, permeable pavement, permeable trenches, and soil infiltration, as shown in Figure 1, which specifically includes the following steps:

[0031] 1) Lay the middle sand layer

[0032] Lay medium sand at the bottom of the trench under the pavement, the particle size range of medium sand is 0.25-0.5mm, the thickness of medium sand laying is 80mm, and tamp down;

[0033] 2) Lay bottom gravel

[0034] Lay clean gravel on the medium sand layer, with a particle size of 20-30mm and a porosity greater than 30%, to ensure that the elevation does not exceed the design elevation;

[0035] 3) laying geotextile

[0036] The permeation pipe is made of PVC pipe with a diameter of 250mm and a length of 8m. The porosity of the pipe is greater than 20%. The length of the geotextile is slightly longer than the length of the pipe to ensu...

Embodiment 2

[0052] A method to make the pavement have a strong ability to store rainwater and reduce rainwater loss. It is realized through the combination of infiltration pipes, permeable pavement, permeable trenches and soil infiltration technologies, as shown in Figure 1, which specifically includes implementation steps and Embodiment 1 is basically the same, the difference is:

[0053] 1) The thickness of the middle sand layer is 120mm;

[0054] 2) The permeation pipe adopts PVC pipe with a diameter of 150mm and a length of 12m;

[0055] 3) The length, width and height of the water collection well are 1×1×2m.

Abstract

The invention discloses a method for enabling a pavement to have strong rainwater storage capacity and reducing rainwater loss. The method is implemented through combination of a percolation pipeline, a permeable pavement, permeable ditches and various technologies including soil infiltration and specifically comprises the following steps: medium sand, bottom rubble, geotextile and the percolation pipeline are laid sequentially at the bottom of a trench below the pavement, the geotextile is folded and performs tight and compact wrapping, the pipeline is completely wrapped with the geotextile, two ends of the percolation pipeline are connected with catchpits respectively, and then rubble around the pipeline, the permeable pavement and surface layer soil are laid sequentially; the ditches are dug in two sides of the permeable pavement, and water absorptive plants are planted. The method has the advantages that through combination of various infiltration technologies, a multipoint rainwater infiltration technology for a sponge city is realized, urban rainwater is drained timely, urban waterlogging is reduced, the urban pavement has strong rainwater storage capacity, and rainwater loss is reduced.

Description

technical field [0001] The invention relates to the rainwater multi-point infiltration technology in the construction of the sponge city, specifically a method for making the road surface have a strong ability to store rainwater and reduce rainwater loss. Background technique [0002] In the process of urbanization, the surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and concrete, forming an ecological "artificial desert". While convenient transportation facilities and paved roads bring convenience to people's travel, these impermeable roads also have a great negative impact on the urban environment. Today, the city's "rainwater disease" is getting worse day by day. These densely surfaced grounds are paved in rainy days due to the hardening of the ground, so that the low-lying areas cannot be drained in time, resulting in large areas of water, resulting in "water drifting phenomenon", which makes driving in rainy days...
