Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The method for displaying backlogs provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings by using specific embodiments and application scenarios thereof.

Please refer to fig. 1-3, the utility model provides a drainage structures 100 for ecological remediation based on mine, include: water collection well 10, geogrid 20, drain pipe 30 and cover plate 40.

The water collecting well 10 is buried on a mine side slope and used for storing rainwater. The water collecting well 10 is prefabricated and formed by concrete, during construction, a foundation pit needs to be excavated on a mine side slope, and then the water collecting well 10 is buried in the foundation pit. The top of the water collecting well 10 is open, and the bottom is closed. Further, the lateral wall bottom of sump pit 10 can also set up the micropore, works as when the interior amasss of sump pit 10 has the rainwater, can be through the osmosis to soil body drainage around, keeps the moist of soil body around, provides moisture for the root system development of the plant in the soil body.

The top of the water collecting well 10 is exposed on the slope of the mine mountain edge, four clamping blocks 11 are formed at the top of the water collecting well 10 in a protruding mode, two adjacent clamping blocks 11 form bayonets 12 at intervals, and it can be understood that the number of the bayonets 12 is four. Preferably, the four fixture blocks 11 are distributed in an annular array along the central axis of the water collecting well 10.

Geogrid 20 bears in on the sump pit, geogrid 20 includes four angles, and every angle is spacing in one bayonet 12 on the sump pit 10, directly utilizes bayonet pair on the sump pit 10 is spacing geogrid 20 does not need extra fixed knot to construct, can restrict geogrid's aversion.

Four water collecting wells 10 and one geogrid 20 form one water collecting unit, and two adjacent water collecting units share two water collecting wells 10. Referring to fig. 1, after the water collecting units are assembled, the slope of the mine slope can be covered in a large area, and the geogrid 20 can fix sand and prevent water and soil loss. A nutrient soil layer and a turf are sequentially laid on the geogrid 20; the nutrient soil is used for providing nutrients for early growth of the turf, and the root system of the turf can directly penetrate through the geogrid 20 and be rooted in a soil body of a mine side slope after being developed, so that the soil stabilization effect can be further enhanced.

The side wall of the water collecting well 10 is further provided with water outlets 13, and the water outlets 13 are correspondingly arranged below the clamping blocks 11 one by one. The two ends of the drainage pipe 30 are respectively communicated with the drainage ports 13 of two adjacent water collection wells 10. Specifically, the drainage pipes 30 include a horizontal drainage pipe 30 for collecting rainwater gathered from the turf and a vertical drainage pipe 30 for draining rainwater overflowing from the upper collection well 10 to the lower collection well. The lowest water collecting well can be communicated with a matched rainwater collecting structure. The device is used for collecting excessive rainwater, carrying out peak regulation and irrigation in drought.

Since the drainage port 13 is located below the projection 11, so that the installation height of the drainage pipe 30 is lower than that of the geogrid 20, rainwater on the turf on the geogrid 20 can be gathered to a low position and enter the drainage pipe 30, the drainage pipe 30 is of a semicircular groove structure, the top of the drainage pipe 30 is open, the gathered rainwater can be conveniently received, and the gathered rainwater is drained into the water collecting well 10 through the drainage pipe 30. Through the drain pipe 30 with the cooperation of sump pit 10 can be collected the rainwater, avoids the rainwater directly to trickle along the mine domatic and causes domatic washing, forms soil erosion and water loss.

The cover plate 40 is matched with the shape of the water collecting well 10 and is pressed on the corners of the geogrid 20, so that on one hand, the geogrid 20 can be limited to move along the longitudinal direction, and on the other hand, a cover can be formed on the top opening of the water collecting well 10, and impurities are prevented from entering the cover.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
