Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses gardens drainage system.
Referring to fig. 1, gardens drainage system includes vegetation layer 1, nutrition soil layer 2, the former soil horizon 3 that sets gradually from top to bottom. Be equipped with water-collecting device on nutrition soil layer 2, water-collecting device is including inlaying many water collecting channel 21 in nutrition soil layer 2, inlaying header tank 22 in nutrition soil layer 2.
Referring to fig. 1, the top end of the water collecting channel 21 protrudes from the upper surface of the nutrition soil layer 2, and one end of the water collecting channel 21 is communicated with the water collecting tank 22. The bottom end of the water collection tank 22 penetrates through the nutrient soil layer 2, is embedded in the original soil layer 3 and is connected with a water pumping pipe 23. One end of the water pumping pipe 23, which is back to the water collecting tank 22, is bent upwards and penetrates through the nutrient soil layer 2, and one end of the water pumping pipe 23, which is positioned on the vegetation layer 1, is fixedly connected with a water pump 24. The water collecting tank 22 is internally provided with a filtering device 4, and the filtering device 4 is positioned below the joint of the water collecting channel 21 and the water collecting tank 22 and above the joint of the water pumping pipe 23 and the water collecting tank 22.
Referring to fig. 1, when rainwater arrives, part of water permeates into a nutrient soil layer 2 to nourish a vegetation layer 1. 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 nutrition soil layer 2, the accumulated water flows over the water collecting channel 21 and flows into the water collecting tank 22 along the water collecting channel 21. The rainwater introduced into the water collecting tank 22 is filtered by the filtering device 4 and stored in the bottom of the water collecting tank 22. The water pump 24 pumps out the filtered water through the water pumping pipe 23 for recycling, so that the rainwater is recycled.
Referring to fig. 1 and 2, the water collecting channel 21 includes a plurality of sub channels 211 arranged in parallel, and a main channel 212 connecting the plurality of sub channels 211. The plurality of sub-runners 211 are evenly distributed on the nutrient soil layer 2, and the nutrient soil layer 2 between the sub-runners 211 is used for planting vegetation. A water inlet 221 is formed at one side of the top of the water collecting tank 22, and one end of the main flow passage 212 facing away from the sub flow passage 211 is communicated with the water inlet 221.
Referring to fig. 1 and 2, when the amount of rainwater is large, the rainwater may not penetrate into the underground water to flow into the respective sub-channels 211, and then may be collected into the main channel 212 through the sub-channels 211, and finally may flow into the sump 22. When water flows into the water collecting channel 21, sundries are easily wrapped, and in order to reduce the possibility that the sundries block the water inlet 221 to influence water drainage, the second filter screen 222 is fixedly connected to the water inlet 221. In order to increase the drainage speed, the sub-channels 211 are obliquely arranged, and one end of the sub-channel 211, which faces away from the main channel 212, is higher than the other end.
Referring to fig. 1, the water collecting channel 21 is built by water permeable bricks, and the accumulated water can permeate into the nutrient soil layer 2 along the side wall of the water collecting channel 21. When the rainfall is large, in the process that water flows into the water collecting tank 22 along the water collecting channel 21, the water permeates into the nutrient soil layer 2 from the bottom wall of the water collecting channel 21, the drainage pressure is relieved, and the drainage speed is accelerated.
Referring to fig. 2, the water collecting tank 22 is rectangular, the top of the water collecting tank 22 is open, and rainwater can directly fall into the water collecting tank 22, so that the drainage pressure on the ground is reduced. At the top fixedly connected with collection rain fill 223 of header tank 22, collection rain fill 223 is big end down's square hourglass shape, makes the rainwater that falls into header tank 22 more, and rainwater admission speed is faster.
Referring to fig. 2, rainwater falling from the top and standing water flowing from the main flow passage 212 contain a large amount of impurities and require filtering before reuse. The filtering device 4 comprises a first filter screen 41, a cobblestone layer 42 and an activated carbon layer 43 which are connected with the inner side wall of the water collecting tank 22 from top to bottom. The rainwater enters the water collecting tank 22 and is filtered by the first filter screen 41, so that the large impurities in the rainwater are blocked above the first filter screen 41. Then flows through the cobble layer 42, and fine impurities in the water are adsorbed by the cobbles. After primary purification, the active carbon passes through the active carbon layer 43, and the active carbon has the functions of removing harmful gases such as benzene and TVOC, sterilizing and deodorizing, and further purifies the water.
Referring to fig. 2, in order to reduce the influence of the excessive impurities on the water storage of the water collecting tank 22 due to the blockage of the first filter 41, the first filter 41 is disposed in an inclined manner, impurities are accumulated on the lower side of the first filter 41 under the action of gravity, and rainwater can continuously flow downwards through the first filter 41 on the other side.
The implementation principle of a gardens drainage system of the embodiment of this application does: when rainwater arrives, part of water permeates the nutrient soil layer 2 to nourish the vegetation layer 1, and some enters the water collecting tank 22 from the rainwater collecting hopper 223. 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 nutrition soil layer 2, the accumulated water flows over the water collecting channel 21 and flows into the water collecting tank 22 along the water collecting channel 21. The rainwater enters the water collecting tank 22 and is filtered by the first filter screen 41, so that the large impurities in the rainwater are blocked above the first filter screen 41. Then flows through the cobble layer 42, and fine impurities in the water are adsorbed by the cobbles. After primary purification, the active carbon passes through the active carbon layer 43, and the active carbon has the functions of removing harmful gases such as benzene and TVOC, sterilizing and deodorizing, and further purifies the water. The water pump 24 pumps out the filtered water through the water pumping pipe 23 for recycling, so that the rainwater is recycled.
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.
