[0002] At present, the main way to maintain the slope is to construct ecological vegetation to gradually complete vegetation restoration and improve the ecological environment. In the process of conventional slope ecological construction or restoration, irrigation is one of the major problems. This is because the slope terrain is limited, which makes it inconvenient to use conventional irrigation vehicles and equipment, and the water storage capacity of the slope is poor, especially in the dry season. Irrigation is not only difficult to operate, but also greatly reduces the irrigation effect.

[0003] At present, there is a technology that uses water collection to solve the problem of slope irrigation. It mainly sets up a water collection tank and a series of filtering devices, and finally uses the collected rainwater to irrigate the slope vegetation. For example, Chinese Patent 202321445882.3 discloses an environmentally friendly rainwater collection and irrigation device for mine ecological restoration, which is equipped with a filter, a water storage tank and an ecological cup, etc. However, the filter and the water storage tank require a lot of earth to be excavated, and the material is also an industrial product, which requires hoisting, backfilling and other construction, and there are problems such as high cost and difficulty in construction.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an in-situ ecological rainwater collection steep slope micro-irrigation system, which utilizes the slope terrain to dig sedimentation troughs and water collection pools on site, does not require large-scale earth excavation and backfilling, does not require mechanical lifting, greatly shortens the construction period, and reduces costs.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] An in-situ ecological rainwater collection steep slope micro-irrigation system comprises a slope surface, a sedimentation trough, a water collection pool, an irrigation trunk pipe and a drainage ditch. The slope surface is formed by connecting a water collection section and an irrigation section from top to bottom. The sedimentation trough and the water collection pool are both arranged in the water collection section. The sedimentation trough is connected with the water collection pool through a water diversion trough, and the water diversion trough is filled with gravel. The water collection pool is arranged near the junction of the water collection section and the irrigation section. One end of the irrigation trunk pipe is connected with the water collection pool, and the other end extends to the bottom of the slope along the slope of the irrigation section. The drainage ditch is arranged on the slope of the irrigation section. A plurality of drip irrigation belts are connected to the irrigation trunk pipe, and the drip irrigation belts are arranged along the left and right sides of the trunk pipe.

[0008] Furthermore, the sedimentation trough, water diversion trough and water collection pool are all excavated on the slope. The sedimentation trough is rectangular or cube-shaped, the water diversion trough is long strip-shaped, and the water collection pool is cylindrical or cube-shaped. The inner wall of the water collection pool is paved with a geomembrane.

[0009] Furthermore, the depth of the sedimentation tank is 30-50 cm, the depth of the water diversion tank is 20-30 cm, and the depth of the water collection pool is 80-150 cm.

[0010] Furthermore, the gravel filled in the water diversion trough includes several particle sizes.

[0011] Furthermore, one end of the irrigation main pipe connected to the water collection tank passes through a portion of the slope and is communicated with the bottom of the water collection tank. A gate valve and a pressure regulating valve are installed on the irrigation main pipe.

[0012] Furthermore, a plurality of drip irrigation belts are distributed on both sides of the irrigation main pipe in a tree-branch shape, and the spacing between adjacent drip irrigation belts is 30-150 cm.

[0013] Furthermore, the diameter of the irrigation main pipe is 20 cm, and the diameter of the drip irrigation tape is 16 cm.

[0014] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0015] The utility model utilizes the slope terrain to dig out sedimentation troughs and water collection pools on site, and uses crushed stone to fill the water diversion trough to achieve a filtering effect. All of these materials are locally sourced. Compared with traditional finished equipment hoisting, backfilling and other construction, the utility model has a greatly shortened construction period and low cost. After the slope ecological restoration is completed, no waste industrial products will be left behind to affect the ecology.

The slope is formed by a water collection section 11 and an irrigation section 12 connected from top to bottom. The segmentation here is for the convenience of description. The water collection section 11 mainly plays a role in collecting water. The sedimentation trough 2 and the water collection pool 4 are both arranged in the water collection section 11. The irrigation section 12 is the main part of the slope for irrigation. Here, the water collection section 11 is preferably a gentle section, and the irrigation section 12 is a steep section. The attached figure is only for this example structure. Of course, the actual water collection section 11 is arranged according to the actual slope trend and is not limited to a gentle section. The sedimentation trough 2 is connected to the water collection pool 4 through the water diversion trough 3, and the water diversion trough 3 is filled with gravel 301. The gravel 301 mainly plays a filtering role. Gravel 301 of different particle sizes can be used in combination. The water collection pool 4 is located at the end, and can be arranged near the junction of the water collection section 11 and the irrigation section 12, which is also convenient for water diversion and irrigation.

[0025] Here, the sedimentation trough 2, the water diversion trough 3, and the water collection pool 4 are all formed by digging on the slope, excavating on the spot, and forming each part of the structure by digging pits. In conjunction with the accompanying drawings, the sedimentation trough 2 is in the shape of a rectangular parallelepiped or a cube, the water diversion trough 3 is in the shape of a long strip, and the water collection pool 4 is in the shape of a cylinder or a cube, wherein the size, size, volume, etc. of the sedimentation trough, the water diversion trough 3, and the water collection pool 4 are mainly adjusted according to the water collection amount and the irrigation amount.
