Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering seepage prevention and ecological restoration technology, specifically to the seepage prevention and ecological restoration wall structure of reservoirs in arid areas. Background Technology

[0002] Reservoirs in arid regions are prone to cracking and leakage due to the dry climate and large temperature differences between day and night. Existing anti-seepage structures mostly use single rigid materials, which are disconnected from ecological restoration functions and cannot meet the needs of both seepage prevention and ecological restoration. At the same time, the groundwater level in arid regions fluctuates greatly seasonally, and the junction between the bottom of the wall and the foundation is prone to seepage channels due to soil shrinkage and expansion. Traditional foundation structures lack effective water-stopping measures. In addition, rainfall in arid regions is concentrated and short-lived, and rainwater can easily seep down from the top of the wall into the interior, exacerbating the damage to the wall structure. Utility Model Content

[0003] In view of the problems existing in the current ecological restoration wall structure for seepage prevention in reservoirs in arid areas, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an ecological restoration wall structure for seepage prevention in reservoirs in arid areas, which solves the problem of cracking and leakage caused by the interaction of wet and dry cycles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An ecological restoration wall structure for seepage prevention in reservoirs in arid areas includes a wall. The outer wall of the wall is sequentially fitted with an anti-seepage layer, a buffer layer, and an ecological layer from the inside out. A base structure is fixed at the bottom of the wall, with flanges fixed on both sides of the base structure. Fitting grooves are fixedly opened on the flanges, and elastic water-stopping elements are fixed within the fitting grooves. A drainage trough is fixed at the top of the wall, and a drainage pipe is fixedly installed within the drainage trough. The drainage pipe is L-shaped. A grouting channel is fixed at the top of the base structure, and a rod is installed within the grouting channel.

[0006] Preferably, the base structure is provided with a first filter layer and a second filter layer from bottom to top.

[0007] Preferably, the impermeable layer is a bentonite composite impermeable layer, and a reinforcing frame is fixedly provided on one side of the impermeable layer.

[0008] Preferably, the buffer layer is a ceramsite concrete layer, and a corrugated metal sheet is fixedly provided on one side of the buffer layer.

[0009] Furthermore, the ecological layer is made of permeable concrete, and planting holes are spaced along the height direction on the outer surface of the ecological layer.

[0010] Preferably, the first filter layer is a graded crushed stone layer, and the second filter layer is a filament spun clay fabric layer.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model utilizes the synergistic effect of the impermeable layer, reinforcing frame, buffer layer, and corrugated metal sheet to effectively resist the stress caused by the diurnal temperature variation in arid regions, preventing cracking and damage to the impermeable layer and significantly improving the stability and durability of the overall impermeability of the wall. The ecological layer uses permeable concrete with planting holes, enabling the integration of drought-resistant plant planting with the wall structure, while also considering ecological restoration functions. The interlocking grooves of the foundation structure, combined with elastic water-stopping components and a double-layer filter layer, can block leakage channels at the wall-foundation junction, prevent the loss of foundation soil particles, and ensure the stability of the wall structure.

[0012] 2. The drainage system consisting of the top drainage channel and the L-shaped drainage pipe of this utility model can quickly discharge concentrated rainfall and prevent rainwater from seeping down the top of the wall and damaging the internal structure. The combination design of the grouting channel and the rod can enhance the anchoring force between the wall and the foundation, adapt to the seasonal fluctuation of groundwater level in arid areas, and extend the overall service life of the reservoir wall.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model discloses an ecological restoration wall structure for seepage prevention in reservoirs in arid areas.

[0018] This utility model provides, for example Figure 1-3The ecological restoration wall structure for seepage prevention in a reservoir in an arid region, as shown, includes a wall 1. From the inside out, the outer wall of the wall 1 is sequentially fitted with a seepage-proof layer 2, a buffer layer 3, and an ecological layer 4. A base structure 5 is fixedly installed at the bottom of the wall 1. Flanges 6 are fixedly installed on both sides of the base structure 5. An interlocking groove 7 is fixedly opened on the flange 6, and an elastic water-stopping element 8 is fixedly installed within the interlocking groove 7. A drainage channel 9 is fixedly installed at the top of the wall 1, and a drainage pipe 10, L-shaped, is fixedly installed within the drainage channel 9. A grouting channel 11 is fixedly installed at the top of the base structure 5. The grout channel 11 is equipped with a rod 12. The outer wall of the wall 1 is arranged from the inside to the outside, with an impermeable layer 2, a buffer layer 3, and an ecological layer 4 forming a core protection system. The impermeable layer 2 is made of bentonite composite material, which has excellent impermeability. At the same time, the reinforcing frame 15 fixed on one side can improve the tensile strength and damage resistance of the impermeable layer 2, and avoid structural deformation caused by the diurnal temperature difference in arid areas, which would damage the integrity of the impermeable layer 2. The buffer layer 3 is a ceramsite concrete layer, and the corrugated metal sheet 16 fixed inside can actively absorb the stress generated by the wet and dry cycle, and disperse and dissipate the impact of the deformation of the wall 1 on the impermeable layer 2. To further ensure the seepage prevention effect of the seepage barrier layer 2, the ecological layer 4 is made of permeable concrete, which does not hinder the appropriate water exchange between the buffer layer 3 and the outside. The vegetation holes 17 opened along the height direction on its outer surface allow the roots of drought-resistant plant seeds to penetrate deep into the ecological layer 4 after germination, enhancing the stability of the bond between the ecological layer 4 and the buffer layer 3, while simultaneously achieving ecological restoration of the outer side of the wall 1. The base structure 5 at the bottom of the wall 1 is crucial for preventing wall foundation leakage and protecting the foundation. Fitting grooves 7 are opened on the flanges 6 on both sides of the base structure 5. The fitting grooves 7 are adapted to the pre-set foundation structure, and the elastic water-stopping components 8 fixed in the grooves... After water ingress, the wall expands, tightly filling the gap between the interlocking groove 7 and the foundation, blocking the leakage channel at the junction of the bottom of the wall 1 and the foundation from the source. The first filter layer 13 and the second filter layer 14 set from bottom to top in the foundation structure 5 form a gradient filtration system. The graded crushed stone layer can filter water that seeps into the foundation, preventing the foundation soil particles from being lost with the water. The long-filament spun clay geotextile layer further intercepts fine particles. The double filtration protects the stability of the foundation structure and avoids the impact of foundation settlement on the overall seepage prevention and stability of the wall 1. The drainage trough 9 fixed at the top of the wall 1 can quickly collect concentrated and short-lived rainfall in arid areas. The L inside the trough The drainage pipe 10 can guide the collected rainwater to the outside of the reservoir dam body, preventing rainwater from seeping into the interior of the wall 1 through the gaps at the top of the wall 1, and preventing seepage water from accelerating the aging and leakage of the wall 1 structure. The grouting channel 11 at the top of the foundation structure 5 works with the internal rod 12 to achieve anchoring and reinforcement. The rod 12 can be inserted into the deep foundation. Grout is injected into the gap between the foundation and the rod 12 through the grouting channel 11. After the grout solidifies, it can enhance the bonding force between the rod 12 and the foundation, improve the overall pull-out resistance and settlement resistance of the wall 1, adapt to the impact of seasonal fluctuations in groundwater level in arid areas on the stability of the wall 1, and ensure the long-term stable operation of the wall 1.

[0019] For easy filtering, such as Figure 1 As shown, the base structure 5 is provided with a first filter layer 13 and a second filter layer 14 from bottom to top.

[0020] And for greater durability, such as Figure 2 As shown, the seepage barrier 2 is a bentonite composite seepage barrier 2, and a reinforcing skeleton 15 is fixedly provided on one side of the seepage barrier 2.

[0021] And for better buffering, such as Figure 3 As shown, the buffer layer 3 is a ceramsite concrete layer, and a corrugated metal sheet 16 is fixedly provided on one side of the buffer layer 3.

[0022] Finally, for ease of planting, such as Figure 4 As shown, the ecological layer 4 is a permeable concrete layer, and vegetation holes 17 are opened at intervals along the height direction on the outer surface of the ecological layer 4. The first filter layer 13 is a graded crushed stone layer, and the second filter layer 14 is a filament spun clay fabric layer.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
