The drainage channels 3 can be straight, zigzag or curved according to the trend of the street 1. Above the drainage channels 3, there are several drainage channel openings for the water on the road surface of the street 1 to flow into the drainage channels 3. A channel cover plate 31 can be detachably installed on each drainage channel opening, and a drainage channel filter frame 32 can be detachably arranged in the drainage channel 3 below the channel cover plate 31; the road surface of the street 1 is lower than the building foundation 2 of the building 9. The foundation is built to 10 - 40 cm to prevent the bottom of the building from being soaked by water. The roof of the building uses a sloping roof with a certain radian for drainage, and the rainwater is conducted into the street drainage system; the street road surface slopes slightly towards the drainage channel and the rain well to facilitate the water to flow into the drainage channel and the rain well;
[0029] It further includes a reservoir 4 underground in the street 1 arranged between the two drainage channels 3. Above the reservoir 4, a rain well 6 extends and connects to the road surface of the street 1. The upper end of the rain well 6 is detachably provided with a well cover 61, and a rain well filter 62 is detachably arranged in the rain well 6 below the well cover 61;
[0030] On one side wall of the upper part of the drainage channel 3, there is a drainage channel interface 33. On the upper wall of the reservoir 4, there is a reservoir interface 41. The plane of the drainage channel interface 33 is higher than the plane of the reservoir interface 41. An overflow pipe 5 is connected between the drainage channel interface 33 and the reservoir interface 41.
[0031] The end of the drainage channel 3 is arranged adjacent to a river or a lake 8. The end of the drainage channel 3 is directly connected to the river or the lake 8 or the water is drained into the river or the lake 8 through a drainage device connected to the drainage channel. The bottom of the reservoir 4 is connected to the river or the lake 8 through a pipeline or the water is drained into the river or the lake 8 through a drainage device connected to the pipeline.
[0032] Among them, several of the drainage channel openings are evenly distributed on the drainage channel 3.
[0033] Among them, a shielding structure is arranged on the drainage channel 3 between several of the drainage channel openings. Among them, the shielding structure can be a flower bed, a decoration, etc., which are structures for beautifying and decorating. The unopened part of the drainage channel 3 can be hidden under structures such as flower beds and decorations. And it can be transformed without changing the layout of the existing street functional areas.
[0034] Among them, several water inlet holes are vertically opened on the water channel cover plate 31. Several of the water inlet holes are within the range of the drainage channel filter frame 32. The drainage channel filter frame 32 abuts against the bottom surface of the water channel cover plate 31.
[0035] Among them, a first placement platform is arranged on the inner wall of the drainage channel 3. A drainage channel filter frame is arranged on the outer peripheral wall of the top of the drainage channel filter frame 32. The drainage channel filter frame 32 is placed on the first placement platform through the drainage channel filter frame.
[0036] Among them, the inner wall of the drainage channel 3 is a smooth wall surface. Among them, the inner wall of the drainage channel 3 is a smooth wall surface, which can accelerate the water flow velocity. The smooth wall surface can be made by polishing the concrete surface or can be veneered with a material with a smooth surface (such as tiles, etc.). It is convenient for the staff to clean, maintain and repair the inner wall of the drainage channel 3, ensure the smoothness of the inner wall of the drainage channel 3, and thus ensure the flow velocity of the open channel 1. Among them, for the smooth wall surface, the convexity and concavity error per square centimeter area ≤ 0.3 microns. When the smooth wall surface is adopted inside the drainage channel 3, the flow velocity can reach more than 20 m / s. Compared with the existing underground pipe network flow velocity of 0.5 - 2 m / s, the flow velocity can be effectively increased.

[0040] The working principle of the present utility model: When in use, during rain, rainwater will flow towards the drainage channel and the rainwater well. The filters in the drainage channel and the rainwater well can play a role in intercepting sundries. The intercepted sundries can be cleaned by subsequently opening the manhole cover and the drainage channel cover. The water in the drainage channel will flow along the drainage channel into rivers or lakes. The rainwater falling into the rainwater well will flow into rivers or lakes through pipelines. A drainage device can be added as needed to accelerate the drainage process. Through the smooth inner wall of the drainage channel, the drainage flow rate can be accelerated. In cooperation with the overflow pipe, when the rainfall is large, the water level in the drainage channel rises too fast. At this time, the rainwater will flow into the rainwater well through the overflow pipe and be diverted through the rainwater well to avoid the retention of rainwater on the road surface due to heavy rain and prevent the phenomenon of heavy rain and waterlogging; the semi-open design of the drainage channel has flexible connections, reduces the land area and improves the complexity of the streets and alleys.
