Problems solved by technology

[0006] Although the traditional drainage device 1 also has the drainage effect of extending downward, since there is no separation protection between the clean water tank 11 and the underground soil, the underground soil is easy to flow into the clean water tank 11 with the flow of water or groundwater, and is filled in the clean water tank 11 In the voids (PoreSpaces) of the filling material 12, the drainage effect of the filling material 12 is gradually reduced or lost, so that the service life of the drainage device 1 cannot last, and it is easy to cause the problem of soil structure collapse

Abstract

A subsurface drainage channel comprises at least one drainage device. The drainage device is arranged downwards from the surface and comprises a columnar permeable unit and a coating layer, wherein the permeable unit comprises high-porosity fillers, and the coating layer coats the permeable unit and is permeable. By the design, the contact circulation mode of surface runoff water and soil is changed from traditional horizontal distribution into extension and diffusion towards the subsurface by columnar surface area, the occupied usable area of the subsurface drainage channel on the surface can be substantially saved, drainage area dozens of times to hundreds of times more than the original is created, land utilization efficiency is improved, the service life of the subsurface drainage channel is effectively prolonged, and further, the surface runoff water can be guided and conserved into an underground water source for use.

Description

technical field [0001] The invention relates to a drainage channel, in particular to an underground drainage channel. Background technique [0002] In the environment where human beings live, there must be a supply of fresh water to maintain basic survival and meet the needs of other human activities. The largest source of fresh water on the surface is the melted snow water from rainfall or snowfall, which is collected into streams to form rivers, or hidden underground to become groundwater, and finally accumulated to become fresh water available for human life. [0003] As the population density increases, the development of the surface becomes more and more serious. In urban areas with high population density, due to the needs of residents' activities, a large amount of land must be used for various activities, such as commerce, transportation, social interaction, sports, etc. Therefore, a large amount of land has been paved with artificial paving, such as concrete or as...
