Detailed Description

The invention will be further described with reference to the following examples.

The present invention will be further described with reference to the following examples, as shown in fig. 1, 2 and 3.

The pressure release regulation of being suitable for sponge city of this embodiment oozes row integration inlet for stom water includes:

the rainwater drainage structure comprises a lower concave green land 1, wherein the lower concave green land 1 is used for storing rainwater, a rainwater inlet 2 is arranged in the lower concave green land 1, an openable cover plate 3 covers the rainwater inlet 2, a water inlet hole 31 for allowing rainwater to enter the rainwater inlet 2 is formed in the cover plate 3, a drainage pipe 4 is arranged in the rainwater inlet 2, the drainage pipe 4 is used for draining the rainwater in the rainwater inlet 2, the rainwater inlet 2 is arranged at the bottom of the rainwater inlet 2 and comprises an inner wall 21 and an outer wall 22, gravel is filled between the inner wall 21 and the outer wall 22 to form a middle layer 23, a rainwater vertical pipe 5 is arranged in the middle layer 23, rainwater on a roof flows into the middle layer 23 through the rainwater vertical pipe 5, a primary rainwater drainage hole 222 is formed in the bottom of the outer wall 22, and the primary rainwater drainage hole 222 is used for draining and draining primary rainwater stored in the middle.

When the collected rainwater flows into the middle layer 23, gaps exist among gravels in the middle layer 23, the initial rainwater enters the gaps and is discharged through the primary rainwater discarding hole 222, the primary rainwater discarding hole 222 discharges the primary rainwater into a soil layer, primary rainwater discarding of the rainwater port 2 is realized, and when the rainwater on the roof is collected to a certain height on the concave greenbelt 1, the rainwater flows over the cover plate 3 covering the rainwater port 2 and enters the rainwater port 2 through the water inlet hole 31. Simultaneously, the discharge opening 222 is abandoned to the rain 2 bottom of inlet for the rainwater can be partly by intermediate level 23 infiltration to the soil layer in, ensures that the regulation of rain just holds and for the moisturizing of underground plant root system.

Further, the plurality of initial rain discarding holes 222 are uniformly arranged at the bottom of the outer wall 22. Preferably, there are six primary rain discard orifices 222. The width of the primary rain discarding hole 222 is 15mm so that the primary rain can penetrate into the soil layer through the primary rain discarding hole 222.

Further, concave greenery patches 1 includes vegetation soil layer 11 and seepage flow layer, permeable formation 12 is established to the bottom of outer wall 22, vegetation soil layer 11 is used for planting the vegetation, the water seepage flow of vegetation soil layer 11 is in permeable formation 12.

Furthermore, the side surface of the outer wall 22 is provided with an overflow hole 221, and the overflow hole 221 allows rainwater stored in the concave green space 1 to flow into the intermediate layer 23 through the overflow hole 221. A row of slender overflow ports 221 are arranged above the outer wall 22 of the gutter inlet 2 in a circle and are arranged on the outer wall 22 along the vertical direction to the vegetation soil layer 11. Overflow hole 221 will the time of the certain height is submerged to concave greenery patches 1 water and discharges into in gutter inlet 2, one row is long and thin the overflow mouth can alleviate the rainwater to the erodeing of plants such as meadow, has avoided the rainwater to the erodeing of concave greenery patches 1, and the vegetation soil layer 11 that causes is erodeed, makes concave greenery patches 1 possess better regulation ability.

Further, the high-rise rainwater pipe 7 is further included, the high-rise rainwater pipe 7 is connected with a high-rise building 6 and a middle layer 23, and the high-rise building 6 is a building higher than the highest point of the concave green land 1. Specifically, the rainwater pipe is connected in the gravel gap of the middle layer between the inner wall and the outer wall, rainwater passing through the high-rise building 6 directly flows to the concave green space 1, due to the height difference, large impact pressure to the concave green space 1 is easily caused, the rainwater of the high-rise building 6 enters the middle layer 23 through the high-rise rainwater pipe 7, the impacted rainwater is buffered and decompressed through gravel, and decompression effect can be achieved on the rainwater falling from the high-rise building 6. Then flows back to the concave green land 1 through the overflow hole 221, so that the scouring pressure of the rainwater of the high-rise building 6 on the concave green land 1 can be avoided.

It is right above the utility model relates to a be suitable for pressure release regulation in sponge city and ooze row integration inlet for stom water and introduced in detail, it is right to have used specific individual example in this paper the utility model discloses a principle and embodiment have been expounded.
