Description

Technical Field

[0001] The utility model relates to the technical field of mine restoration, in particular to a geocell structure for planting cliff vegetation. Background Art

[0002] At present, the vegetation planting technology for mine ecological restoration mainly adopts the traditional hole-shaped soil covering and tree planting method, which is suitable for areas with gentle slopes and easy excavation. However, the high slopes formed by most mine excavations are relatively steep and nearly vertical in some places, which is not conducive to vegetation planting in the early stage and plant growth in the later stage, resulting in low plant survival rate and poor slope restoration effect. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a geocell structure for planting cliff vegetation, which can specifically adopt the following technical solutions:

[0004] The geocell structure for planting cliff vegetation described in the utility model comprises a geocell arranged on a cliff slope staggered platform, wherein the geocell and the cliff slope staggered platform constitute a soil filling area of ​​an upper opening structure, the bottom plate of the geocell is connected to the cliff slope staggered platform through anchor rods, an organic soil layer for planting trees or shrubs is arranged in the soil filling area, and the inner side wall of the cliff slope staggered platform is a vine plant planting area.

[0005] The geocell is formed by splicing a plurality of L-shaped reinforced concrete prefabricated parts along the longitudinal direction of the cliff slope.

[0006] The width of the reinforced concrete prefabricated parts is adapted to the staggered slope of the cliff, and the length of each section of the reinforced concrete prefabricated parts is 1.0-1.5m.

[0007] The anchor rods are arranged in a row along the longitudinal direction of the cliff slope staggered, and are arranged in a row at the center of the bottom plate of the geocell and at the inner side of the bottom plate close to the cliff slope staggered.

[0008] One row of anchor rods at the center of the bottom plate is arranged vertically, and the other row is arranged obliquely downward toward the inner side of the cliff.

[0009] The length of the anchor rod is 1.0 m, and the spacing between adjacent anchor rods in the same row is 1.5 m.

[0010] The outer surface of the anchor rod is provided with a varnish anti-corrosion layer, and the inner cavity of the anchor rod is provided with a cement mortar injection body with a strength greater than 30MPa.

[0011] The cliff side slope is staggered and arranged in multiple levels from top to bottom.

[0012] The geocell structure for planting vegetation on steep slopes provided by the utility model is convenient to construct, highly safe, and has a high survival rate of vegetation. The geocell is built on the slope offset as a planting trough for vegetation, and is fixed to the slope offset with anchor rods to ensure the safety and stability of the geocell. Organic soil is then added to the geocell, thus ensuring the growth environment required by the vegetation. The utility model has low cost and good effect, and can effectively solve the contradictory problem that vegetation on steep slopes is difficult to plant and has a low survival rate after planting. It can not only ensure the safety of the slope, but also improve the greening and repair effect of the slope. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific construction process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0015] like Figure 1 As shown, the geocell structure for planting cliff vegetation described in the utility model includes a multi-level cliff slope staggered arranged from top to bottom, and a geocell 1 is installed on each cliff slope staggered. The above-mentioned geocell 1 is formed by splicing multiple sections of L-shaped reinforced concrete prefabricated parts along the longitudinal direction of the cliff slope staggered, and it and the cliff slope staggered form a soil filling area of ​​the upper opening structure. The steel bars used in the above-mentioned reinforced concrete prefabricated parts are HREB400, and the concrete is C35. The bottom plate of the geocell 1 is attached to the cliff slope staggered. Usually, the width of each section of the reinforced concrete prefabricated part is adapted to the cliff slope staggered, and the length is 1.0-1.5m.

[0016] In order to firmly install the reinforced concrete prefabricated parts of the geocell 1 on the cliff slope staggered platform, a row of mounting holes extending longitudinally along the cliff slope staggered platform are respectively opened at the center of the bottom plate of the geocell 1 and the inner side of the bottom plate close to the cliff slope staggered platform, and a 1.0m long anchor rod 2 is installed in each mounting hole. The anchor head and the outer surface of the free section of each anchor rod 2 are painted with clear paint as an anti-corrosion layer, and the inner cavity is poured with cement mortar with a strength greater than 30MPa. Usually, the spacing between adjacent anchor rods 2 in the same row is set at 1.5m, and one row of anchor rods 2 at the center of the bottom plate is set vertically, and the other row of anchor rods 2 is set downwardly inclined toward the inner side of the cliff.

[0017] After the geocell 1 is installed, the soil filling area of ​​the upper opening structure formed by the offset between the geocell 1 and the cliff slope is filled with organic soil for planting trees or shrubs. The soil surface is flat to ensure the living environment required by the vegetation and improve the survival rate of the vegetation. The inner wall of the offset of the cliff slope is a vine planting area for planting green plants such as creepers to replant the exposed bedrock surface that has not been regreened.

[0018] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
