Description

Technical Field

[0001] This utility model belongs to the field of ecological bank protection technology, specifically relating to an ecological bank protection system for coal gangue in coal mining subsidence areas. Background Technology

[0002] Ecological revetments mainly consist of slope protection, small animals, aquatic plants, and microorganisms. Common cross-sectional slope protection structures include stone slope protection, concrete slope protection, and geotechnical slope protection.

[0003] Currently, the slope protection in riverbank protection is generally made of coal gangue. However, the existing coal gangue is generally large in volume. During the laying process, cement mortar cannot be evenly filled into the gaps of the coal gangue, resulting in voids in the slope protection. When soil for planting vegetation is laid on the slope protection, the soil will sink into the voids, leading to soil erosion. After a period of time, this will cause the ground where vegetation is planted to collapse, affecting the growth of vegetation. At the same time, the large number of voids will affect the stability of the slope protection. Utility Model Content

[0024] refer to Figures 1 to 6 An ecological revetment for coal gangue in a coal mining subsidence area includes a coal gangue base layer 1, which is laid on the foundation. The coal gangue base layer 1 has a framework 2, which includes several horizontal pipes 3 and connecting pipes 4. The horizontal pipes 3 are evenly distributed in the coal gangue base layer 1, and the connecting pipes 4 are connected between the horizontal pipes 3. The walls of the horizontal pipes 3 and the connecting pipes 4 are provided with material guiding holes 5. Several material guiding pipes 6 are provided at the top of the coal gangue base layer 1, and the bottom ends of the material guiding pipes 6 are connected to the horizontal pipes 3 at the top of the framework 2. Several insert rods 7 are detachably connected to the bottom of the framework 2, and the bottom of the insert rods 7 are inserted into the foundation, which improves the tightness of the connection between the coal gangue base layer 1 and the foundation.

[0025] To improve the stability of frame 2, frame 2 is a horizontal cage structure.

[0026] To facilitate the connection between the horizontal pipe 3 and the connecting pipe 4, a tee connector 8 is provided at the end of the horizontal pipe 3, and the horizontal pipe 3 and the connecting pipe 4 are connected through the tee connector 8.

[0027] To enhance the support strength and stability of the horizontal pipe 3 and the connecting pipe 4, both the horizontal pipe 3 and the connecting pipe 4 are provided with reinforcing members 9. The reinforcing members 9 include several cross support frames 10 and steel bars 11. Several collars 12 are provided on the cross support frames 10, and the steel bars 11 are movably inserted through the collars 12 on the same axis.

[0028] To facilitate the handling of the insertion rod 7 and the connector 13, the top end of the insertion rod 7 is connected to the connecting pipe 4 at the bottom of the frame 2 via the connector 13. The connector 13 includes a first pipe clamp 14 and a second pipe clamp 15. The two ends of the first pipe clamp 14 and the second pipe clamp 15 are connected by bolts 16.
