Detailed Description

The present application is described in further detail below with reference to fig. 1.

The embodiment of the application discloses sponge urban green belt drainage device.

Referring to fig. 1, the sponge urban green belt drainage device comprises a vegetation layer 1, a nutrient soil layer 2 and an original soil layer 3 which are sequentially arranged from top to bottom. The nutrient soil layer 2 is lower than the road surface, so that the possibility of water and soil loss caused by the fact that soil is flushed to the road surface by water flow is reduced. A plurality of first water discharge channels 4 are embedded in the nutrient soil layer 2, and the top ends of the first water discharge channels 4 protrude out of the upper surface of the nutrient soil layer 2. The first water flow channels 4 of multichannel set up and be parallel to each other, and nutrition soil layer 2 between the adjacent first water flow channels 4 is used for planting the vegetation.

Referring to fig. 1, the both ends of first row of rivers way 4 all are connected with water drainage tank 6, and first row of rivers way 4 and water drainage tank 6 intercommunication, 6 open-tops of water drainage tank, the bottom run through nutritive soil layer 2 and inlay in former soil layer 3. The welding of the bottom surface middle part of water drainage tank 6 has drainage pipe 7, and drainage pipe 7 is vertical to be set up and with water drainage tank 6 intercommunication, and the bottom of a plurality of drainage pipes 7 is linked together through infiltration drain pipe 8. The infiltration drain pipe 8 is horizontally arranged, and two ends of the infiltration drain pipe 8 are communicated with the urban sewage pipe network.

Referring to fig. 1, when rainwater or flood comes, part of water permeates into a nutrient soil layer 2 to nourish vegetation. Part of the water flow permeates the nutrient soil layer 2, enters the original soil layer 3 and is absorbed by the original soil layer 3. The water flow which cannot be absorbed by the original soil layer 3 continues downwards to become underground water. When too much water flows into the nutrient soil layer 2 too late, the accumulated water flows over the top end of the first drainage channel 4 to enter the first drainage channel 4 and flows into the drainage groove 6 along the first drainage channel 4, and the water in the drainage groove 6 flows into the urban sewage pipe network along the drainage pipe 7 and the permeation drainage pipe 8. The water that has not reached the drain pipe is temporarily stored in the drain tank 6 and is discharged into the drain pipe 7 after the drain pressure is relaxed.

Referring to fig. 1, the drain tank 6 is open, so that foreign materials are easily dropped into the drain tank 6 by natural phenomena, and a filter tub 61 is placed in the drain tank 6 in order to reduce the possibility of clogging the drain pipe 7 by the accumulated foreign materials. When the sundries are excessively gathered to affect drainage, the filter barrel 61 can be taken out and placed into the drainage groove 6 after cleaning.

Referring to fig. 1, in order to increase the speed of collecting the accumulated water into the drain tank 6, the middle portion of the first drain flow passage 4 is higher than both ends. After the water flows into the first water drainage channel 4, the water quickly flows to the water drainage groove 6 along the cambered surface of the first water drainage channel 4 under the action of gravity. In order to accelerate the drainage speed of the green belt, a second drainage flow passage 5 is embedded on the nutrition layer. The second drainage flow channels 5 are provided with a plurality of channels, spaces for planting vegetation are reserved between the adjacent second drainage flow channels 5, and the second drainage flow channels 5 are perpendicular to the first drainage flow channels 4. The same as the first drainage channel 4, the same drainage groove 6 and the same drainage pipeline 7 are provided at two ends of the second drainage channel 5, and the structure of the second drainage channel 5 is the same as that of the first drainage channel 4, and the description thereof is omitted. The second drainage channel 5 is matched with the first drainage channel 4, so that the drainage range is expanded, and the drainage speed is improved.

Referring to fig. 1, the first drainage channel 4 and the second drainage channel 5 are communicated with each other, and due to the difference of topography, when the drainage pressure is large, the water flow can turn at the intersection to relieve the drainage pressure. First drainage runner 4 and second drainage runner 5 adopt the brick of permeating water to build, and rainfall is hour, and ponding can be along the lateral wall infiltration nutrition soil layer 2 of first drainage runner 4 and second drainage runner 5, and when rainfall was big, rivers flowed in water drainage tank 6 along first drainage runner 4 and second drainage runner 5 in-process, from the diapire infiltration nutrition soil layer 2 of first drainage runner 4 and second drainage runner 5, and the drainage pressure of releiving for drainage speed.

Referring to fig. 1, when the accumulated water overflows into the drainage channel 6 too much, sundries on some green belts can be wrapped up and carried, the water flow carries the sundries to enter the first drainage flow channel 4 and the second drainage flow channel 5, in order to reduce the possibility that the sundries block the first drainage flow channel 4 and the second drainage flow channel 5 and influence the water flow to enter the drainage channel 6, the first drainage flow channel 4 and the second drainage flow channel 5 are both welded with filter screens 41. In order to reduce the sundries accumulated on the filter screen 41, the middle part of the filter screen 41 in the width direction is higher than the two sides, and the sundries slide down along the slope of the filter screen 41 after being separated by the filter screen 41, so that the first drainage flow passage 4 and the second drainage flow passage 5 can normally drain water.

The implementation principle of the sponge urban green belt drainage device in the embodiment of the application is as follows: when rainwater or flood comes, part of water permeates into the nutrient soil layer 2 to nourish the vegetation. Part of the water flow permeates the nutrient soil layer 2, enters the original soil layer 3 and is absorbed by the original soil layer 3. The water flow which cannot be absorbed by the original soil layer 3 continues downwards to become underground water. When too much water flow can not permeate the nutrient soil layer 2, the accumulated water flow flows through the top ends of the first drainage flow channel 4 and the second drainage flow channel 5 to enter the first drainage flow channel 4 and the second drainage flow channel 5 and flows into the drainage groove 6 along the first drainage flow channel 4 and the second drainage flow channel 5, and water in the drainage groove 6 flows into the urban sewage pipe network along the drainage pipe 7 and the permeation drainage pipe 8. The water that has not reached the drain pipe is temporarily stored in the drain tank 6 and is discharged into the drain pipe 7 after the drain pressure is relaxed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
