Description

Technical Field

[0001] This utility model relates to the field of dam slope protection, and in particular to a prefabricated anti-collapse slope protection system. Background Technology

[0002] Slope protection is an important structure for protecting the slopes of hydraulic structures such as rivers, canals, reservoirs, and dikes. Its core functions are to maintain slope stability, prevent soil erosion, and ensure the safe operation of the project. Traditional slope protection techniques mostly rely on rigid concrete structures or riprap revetments, which, while possessing erosion resistance, suffer from problems such as ecological damage, long construction periods, and high maintenance costs.

[0003] In related technologies, the implementation of rigid slope protection typically begins with clearing and leveling the slope surface, followed by laying a sand and gravel filter layer to prevent soil erosion. Subsequently, the facing layer is constructed using either mortar-grouted rubble masonry or cast-in-place concrete. Mortar-grouted masonry involves manually laying stones layer by layer, filling the gaps with mortar; cast-in-place concrete is poured after setting up formwork to form a monolithic slab structure. A toothed wall is installed at the bottom of the slope to enhance its anti-sliding properties, and the top is anchored to prevent slope slippage.

[0004] However, this method has obvious drawbacks: it is not adaptable, has high overall stiffness, is difficult to adapt to uneven settlement of the foundation, and is prone to cracks that lead to structural damage. Utility Model Content

[0005] The main purpose of this utility model is to provide a prefabricated anti-collapse slope protection system to solve the problem of slope protection and lifting.

Detailed Implementation

[0019] Example 1 like Figure 1-5 As shown, the prefabricated anti-flood slope protection system includes: a tenon and mortise protection plate, one of which has a first snap-fit ​​block 3 on its top surface, a first snap-fit ​​groove 5 on one side, and a second snap-fit ​​block 4 and a second snap-fit ​​groove 6 on the other two sides respectively. The two tenon and tenon guard plates are provided with rectangular grooves 12 at intervals on both sides. When the two tenon and tenon guard plates are snapped together, the rectangular grooves 12 are connected to form a rectangular hole. The second snap-fit ​​block 4 provided on the two tenon and tenon guard plates is snapped into the first snap-fit ​​groove 5. The two tenon and tenon guard plates are set as a group and there are several groups. In each group of tenon and tenon guard plates, the first snap-fit ​​block 3 is snapped into the second snap-fit ​​groove 6. Each group of tenon and tenon guard plates is distributed in a stepped manner.

[0020] Furthermore, the mortise and tenon joint guard plate features an ingenious design. Each guard plate has a first locking block 3 on its top surface, a first locking groove 5 on one side, and a second locking block 4 and a second locking groove 6 on each of the other two sides. When two guard plates are joined together, the rectangular grooves 12 on both sides align and connect, forming a through rectangular hole for easy fixing of the mortise and tenon joint guard plate. During assembly, adjacent guard plates are longitudinally connected via the second locking block 4 and the first locking groove 5. Multiple sets of guard plates are longitudinally spliced ​​via the first locking block 3 and the second locking groove 6, forming a stepped arrangement. This design ensures structural stability and convenient assembly and disassembly. This design not only enhances the overall impact resistance of the guard plate but also enables modular splicing, making it suitable for various protection needs in different scenarios.

[0021] The tenon and mortise guard plate includes multiple first tenon and mortise guard plates 1, which are respectively snapped into second tenon and mortise guard plates 2.

[0022] Furthermore, the tenon and mortise guard plate is divided into a first tenon and mortise guard plate 1 and a second tenon and mortise guard plate 2. The first snap-fit ​​block 3 and the second snap-fit ​​block 4, which are respectively provided on these two plates, are installed in different positions, and multiple sets of first tenon and mortise guard plates 1 and second tenon and mortise guard plates 2 are snapped together to form a stepped shape to slow down the flow rate.

[0023] Both sides of the first latching block 3 and the second latching block 4 are provided with relatively inclined slopes a, and both sides of the first latching groove 5 and the second latching groove 6 are provided with relatively inclined slopes b, with the inclined surfaces of slopes a and slopes b being arranged in opposite directions.

[0024] Furthermore, the bevels a and b are designed for better interlocking, so that the first tenon and tenon guard plate 1 and the second tenon and tenon guard plate 2 can be more firmly interlocked.

[0025] Hollow pins 13 are provided in the rectangular holes formed by the rectangular grooves 12.

[0026] Furthermore, the center of the pin 13 is hollow. When the pin 13 is driven into the rectangular hole formed by the two connected rectangular grooves 12, the first tenon and the second ...

[0027] A rectangular block 7 is provided between the two rectangular slots 12 on one side. The first snap-fit ​​block 3 and the second snap-fit ​​block 4 are located on the top or side of the rectangular block 7, respectively. The first snap-fit ​​groove 5 and the second snap-fit ​​groove 6 are located between the two rectangular slots 12 on the other side.

[0028] Furthermore, the first snap-fit ​​block 3 and the second snap-fit ​​block 4 are installed in different positions. The first snap-fit ​​block 3 is installed on the top surface of the first tenon and mortise guard plate 1, and the second snap-fit ​​block 4 is installed on the side of the second tenon and mortise guard plate 2. When the first snap-fit ​​block 3 is engaged with the second snap-fit ​​groove 6, each set of first tenon and mortise guard plates 1 and second tenon and mortise guard plates 2 is stepped. When the second snap-fit ​​block 4 is engaged with the first snap-fit ​​groove 6, each set of first tenon and mortise guard plates 1 and second tenon and mortise guard plates 2 is located on the same horizontal line.

[0029] The first tenon and tenon guard plate 1 has a first dovetail tenon 8 at one end and a first dovetail groove 10 at the other end. The second tenon and tenon guard plate 2 has a second dovetail tenon 9 at one end and a second dovetail groove 11 at the other end. The first tenon and tenon guard plate 1 and the second tenon and tenon guard plate 2 are provided horizontally with multiple dovetail tenons 8 and second dovetail groove 11. The first dovetail tenon 8 is engaged with the second dovetail groove 11 and the second dovetail tenon 9 is engaged with the first dovetail groove 10.

[0030] Furthermore, the first tenon and mortise guard plate 1 and the second tenon and mortise guard plate 2 are designed to be interlocked. The first tenon and mortise guard plate 1 has a first dovetail tenon 8 at one end and a first dovetail groove 10 at the other end; the second tenon and mortise guard plate 2 has a corresponding second dovetail tenon 9 and a second dovetail groove 11. When arranged laterally, they are arranged in multiple parallel sets, achieving a firm connection through the precise interlocking of the first dovetail tenon 8 and the second dovetail groove 11, and the embedding of the second dovetail tenon 9 into the first dovetail groove 10. The dovetail tenon and mortise structure has a self-locking characteristic, effectively preventing lateral slippage and improving the overall connection strength and stability.

[0031] Inclined plane a includes a first inclined plane 301 and a second inclined plane 401, and inclined plane b includes a third inclined plane 501 and a fourth inclined plane 601.

[0032] Furthermore, the first inclined surface 301 is provided on both sides of the first snap-fit ​​block 3, the second inclined surface 401 is provided on both sides of the second snap-fit ​​block 4, the third inclined surface 501 is provided on both sides of the first snap-fit ​​groove 5, and the fourth inclined surface 601 is provided on both sides of the second snap-fit ​​groove 6, so as to facilitate the longitudinal connection of the first tenon and tenon guard plate 1 and the second tenon and tenon guard plate 2.

[0033] The hollow pins 13 are equipped with check valves or green plants.

[0034] Furthermore, some of the hollow pins 13 are equipped with check valves, a design that combines structural connection and drainage functions. During heavy rain, seepage water accumulated inside the dam can be discharged unidirectionally through the check valves via the channels of the hollow pins, effectively reducing the pore water pressure inside the earth-rock dam body 16 and preventing landslides or structural instability caused by water pressure buildup. The check valves prevent backflow of external water and debris, ensuring a safe and controllable drainage process. Some of the hollow pins 13 also contain vegetation. These hollow pins 13 not only serve a connecting and reinforcing function, but their internal spaces can be filled with planting soil and planted with moisture-tolerant, well-rooted plants. The plant roots gradually extend into the earth-rock dam body 16, effectively enhancing the dam's erosion resistance and overall stability. Simultaneously, the vegetation cover reduces surface runoff, prevents soil erosion, and enhances the dam's ecological aesthetics and environmental integration.

[0035] Multiple first tenon and second ...

[0036] Furthermore, multiple first tenon-and-mortise retaining plates 1 and second tenon-and-mortise retaining plates 2 are alternately spliced ​​to form a stable and continuous sloping slope surface. The slope protection as a whole has a stepped or smooth sloping surface layout, with each retaining plate tightly interlocked, providing good anti-slip and impact resistance. The first tenon-and-mortise retaining plates 1 and second tenon-and-mortise retaining plates 2 are laid on the earth-rock dam body 16, effectively preventing rainwater erosion, weathering, and loss of topsoil. The tenon-and-mortise connection method eliminates the need for bolts or welding, making installation convenient and adaptable to certain foundation deformations, thus improving the durability and adaptability of the structure.

[0037] Geotextile 15 is laid on the earth-rock dam body 16, and graded crushed stone 14 is laid on the geotextile 15. The slope protection is set on the graded crushed stone 14.

[0038] Furthermore, a layer of high-performance geotextile 15 is first laid on the surface of the earth-rock dam body 16 to serve as a filter, isolate, and drain, effectively preventing the loss of fine soil particles with seepage and improving the dam's anti-seepage stability. Graded crushed stone 14 is then evenly laid on top to form a good permeable cushion layer, which not only facilitates rapid rainwater infiltration and drainage but also evenly distributes the upper load, enhancing the bearing capacity and freeze-thaw resistance of the slope protection foundation. Finally, the slope protection structure, assembled from the first and second tenon-and-mortise retaining plates, is securely laid on the graded crushed stone 14, forming a multi-layered composite protection system of "geotextile—crushed stone cushion layer—prefabricated slope protection."

[0039] Example 2 The first tenon-and-mortise protective plate 1 and the second tenon-and-mortise protective plate 2 are arranged in two different ways. In one arrangement, the first interlocking block 3 in the first tenon-and-mortise protective plate 1 faces upward, and the graded crushed stone 14 is laid thinner and thinner from the top of the earth-rock dam 16. Each set of the first tenon-and-mortise protective plate 1 and the second tenon-and-mortise protective plate 2 are interlocked and laid at an angle downward. In the other arrangement, the first interlocking block 3 in the first tenon-and-mortise protective plate 1 faces downward, and the graded crushed stone 14 is laid thicker and thicker from the top of the earth-rock dam 16. Each set of the first tenon-and-mortise protective plate 1 and the second tenon-and-mortise protective plate 2 are interlocked and laid at an angle downward.
