Embodiment 1

[0025] A method for laying infiltration type rainwater pipelines in sponge city construction, the steps are as follows:

[0026] After the length of the route is measured, the grooves are manually cut, and the grooves are kept away from verticality and slopes are not set. Lay 10cm of medium sand that meets the specification size on the bottom layer, and tamp it down to make it smooth. According to the size of the trench and the length of the lap, determine the length of the geotextile, and then cut the geotextile. The geotextile should be laid flat, and the upper opening of the geotextile should be opened. After the paving of gravel is completed, the upper opening of the geotextile should be closed and overlapped. The particle size of the crushed stone laid at the bottom is 20-30mm, and the porosity is not less than 40%. The infiltration rainwater pipe is connected from the infiltration rainwater well. The diameter of the pipe is 150mm. The gap between the two infiltration r...

Embodiment 2

[0029] A method for laying infiltration type rainwater pipelines in sponge city construction, the steps are as follows:

[0030] After the length of the route is measured, the grooves are manually cut, and the grooves are kept away from verticality and slopes are not set. Lay 5cm of medium sand that meets the specification size on the bottom layer, and tamp it down to make it level. According to the size of the trench and the length of the lap, determine the length of the geotextile, and then cut the geotextile. The geotextile should be laid flat, and the upper opening of the geotextile should be opened. After the paving of gravel is completed, the upper opening of the geotextile should be closed and overlapped. The particle size of the crushed stone laid at the bottom is 20-30mm, and the porosity is not less than 40%. The infiltration rainwater pipe is connected from the infiltration rainwater well. The diameter of the pipe is 300mm. The gap between the two infiltration rai...

Abstract

The invention relates to a method for laying percolation type rainwater drainage pipes in Sponge City Construction. The method comprises the following steps: digging grooves by adopting manpower or a compact excavator, sequentially laying medium sand and bottom gravels, laying and connecting the percolation type rainwater drainage pipes, further laying gravels on the tops and the side surfaces of the pipes, backfilling the grooves with soil, and finally performing treatment on the ground surface by adopting water-permeable concrete or water-permeable asphalt. The method has the advantages that the percolation type rainwater drainage pipes are combined with the permeable pavement, the city rainwater discharge is accelerated, and meanwhile, the water storage capability and the pollutant purification capacity of the pavement and the surrounding soil are improved, so that the method is not only simple but also environmentally friendly.

Description

technical field [0001] The invention relates to a drainage technology in the construction of a sponge city, in particular to a method for laying a percolation type rainwater pipeline in the construction of a sponge city. 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 and ecological system, and the urban "rainwater disease" is becoming more and more serious. Existing urban drainage facilities can no longer meet the requirements of residents' daily life and daily production of enterprises, especially in the case of rapid and concentrated drainage and drainage in rainy weather, there will be problems about drainage. These ...
