Background
With the rapid development of cities, the construction of larger and larger scale improves the living environment of human beings and simultaneously brings about the safety problems represented by urban drainage and waterlogging. In order to overcome the safety problem, the concept of 'sponge city' is proposed, which adopts measures of seepage, stagnation, storage, purification, use, drainage and the like to take and utilize most of rainfall on site.
The existing drainage system of the sponge city is mainly divided into two types, namely one type relies on the self-infiltration of the greenbelt to absorb water, and the other type relies on a rainwater pipe network to drain rainwater into the urban drainage system, but when the urban drainage system encounters rainy season or heavy rain, only the self-infiltration of the greenbelt absorbs water and the rainwater pipe network can not rapidly solve drainage pressure due to large ground runoff and instantaneous flood flow, so that waterlogging phenomenon is easy to occur in the sponge city, and the rainwater is directly drained and is not stored, thereby reducing the utilization of the rainfall. Therefore, it has also been proposed to modify a rainwater pipeline into a water seepage system, such as the sponge rainwater infiltration collecting and draining system proposed by CN206360052U, but the scheme still has large ground runoff and instantaneous flood peak flow in rainy season or heavy rain, the infiltration is not timely enough, and the foundation of the pipeline is impacted by the drainage with large flow and large flow rate, so that the foundation is loose, resulting in potential safety hazard.

The drainage process of the sponge type double-layer pipe drainage system provided by the invention is as follows:
when the rainfall is small, and the rainwater entering the drain pipe 100 is not greater than the infiltration rate of the infiltration pipe 200, the rainwater flows into the lower infiltration pipe 200 due to the gravity when passing through the drain pipe 100 at the upper part, and the rainwater in the infiltration pipe 200 infiltrates into the surrounding soil through the infiltration holes 202 on the pipe wall of the infiltration pipe 200, and at the moment, the rainwater flow rate and the rainwater flow rate are small, so that impact damage to the supporting crushed stone bed 40 is not caused, and the stability of the crushed stone bed 40 can be ensured.
When the rainfall is large, when the rainwater entering the drain pipe 100 exceeds the permeation rate of the water seepage pipe 200, part of the rainwater flows into the lower water seepage pipe 200 due to the gravity effect when passing through the upper drain pipe 100, the rainwater in the water seepage pipe 200 permeates into the surrounding soil through the water seepage holes 202 on the pipe wall of the water seepage pipe 200, and the other part of the rainwater is discharged into the vertical pipe through the drain pipe 100 for temporary storage, and the two ends of the water seepage pipe 200 are sealed by the sealing end covers 210, so that the total amount of the rainwater entering the water seepage pipe 200 is limited, even if the rainfall is large, the rainwater does not directly impact the crushed stone bed 40, the rainwater in the water seepage pipe 200 still permeates into the surrounding soil in a moderate mode, the stability of the crushed stone bed 40 can be ensured, and the soil surrounding the crushed stone bed 40 is not reversely flushed into the water seepage pipe 200.
In this embodiment, the periphery of the drain pipe 100 and the infiltration pipe 200 are preferably coated with a filter fabric 60 to further prevent reverse entry of soil and block the pipe. It is further preferred that the filter fabric is a nonwoven filter fabric (e.g., felt, etc.) to enhance its filtering effect.

In this embodiment, the specific layout of the water outlet holes 202 'on the peripheral wall of the water seepage pipe 200 is shown in fig. 2, the large circle in fig. 2 indicates the axial section of the water seepage pipe 200, the small circle indicates the water outlet holes 202', each group of sub-water seepage holes includes 6 water outlet holes 202', the six water outlet holes 202' may all be located on the same axial section, or the water outlet holes 202 'on a section of long water seepage pipe 200 are projected to the same axial section, wherein, preferably, 6 water outlet holes 202' in each group of sub-water seepage holes are arranged in a staggered manner on a section of long water seepage pipe, which can ensure the strength of the water seepage pipe 200. The 6 water outlet holes 202 'are respectively symmetrical on the peripheral walls of the two axial horizontal sides of the water seepage pipe 200, the included angle between the two adjacent water outlet holes 202' of the 3 water outlet holes 202 'on the same side is 45 degrees, the included angle between the two adjacent water outlet holes 202' on different sides is 90 degrees, namely, the peripheral walls with the included angle of 90 degrees on the top and the bottom of the water seepage pipe 200 are not provided with the water outlet holes 202', so that the impact of rainwater on the crushed stone bed 40 can be reduced when the water seepage pipe 200 permeates water through the water outlet holes 202'. In addition, when sediment deposited in the rainwater is deposited on the seepage pipe 200, the blockage of the gravel bed by the sediment can be reduced, and the seepage effect is weakened.
In this embodiment, preferably, in order to facilitate cleaning of the sediment deposited in the water seepage pipe 200, the sealing end caps 210 at two ends of the water seepage pipe 200 are detachably connected with the water seepage pipe 200, and when the water seepage pipe 200 is blocked or the sediment is more, the sealing end cap 210 at one end can be removed, so that the sediment in the water seepage pipe 200 is flushed into the riser 30 under the action of water flow, and the effect of cleaning and dredging is achieved.
In this embodiment, it is preferable that the peripheral wall and the bottom wall of the stand pipe 30 have a porous structure, so that when the amount of rainwater is large, the rainwater stored in the stand pipe can permeate into the surrounding soil through the holes on the peripheral wall and the bottom wall, thereby intercepting the rainwater to the maximum.
