Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, and more specifically, it relates to a precast concrete slope protection component. Background Art

[0002] Slope protection refers to the measures of strengthening and protecting the slope surface in projects such as rivers, reservoirs, roads, etc. to prevent problems such as soil erosion and bank slope collapse. The slope protection project plays an important role in flood control, disaster resistance, soil conservation, dike protection, etc. When constructing the cast-in-place concrete structure, the concrete has fluidity, and the dike has a slope, so the construction difficulty is extremely high, the process is cumbersome, the construction cost is high, the work efficiency is low, and the project quality is difficult to guarantee. Moreover, it can only be constructed in summer and cannot be constructed in winter. Therefore, precast concrete components are often used for slope protection construction.

[0003] When the existing precast concrete slope protection components are spliced, the connection method is not convenient enough. The conditions at the construction site easily limit the splicing speed of the concrete components, affecting the construction efficiency of the slope protection. The traditional slope protection and wave dissipation components are separately arranged, with poor integrity between the slope protection and wave dissipation and weak anti-scouring ability. At the same time, it is difficult to plant green plants on the slope protection components of the concrete slab, and the water storage capacity of the slope protection wall is not very good, affecting the ecological effect of the slope protection.

[0029] Please refer to Figures 1-5, a precast concrete slope protection component, including a fixing plate 1. There is a fixing groove 2 on the fixing plate 1. Slope protection plates 3 are arranged in an array on the fixing groove 2. Connecting blocks 4 and connecting grooves 5 are provided at the four corners of the slope protection plate 3. A connecting sleeve 6 is provided on the connecting groove 5. A clamping groove 7 is provided on the connecting block 4. A clamping spring 8 and a clamping block 9 are provided in the clamping groove 7. A clamping hole 10 that cooperates with the clamping block 9 is provided on the connecting sleeve 6. A wave-dissipating cross plate 11 and a wave-dissipating longitudinal plate 12 are provided on the fixing plate 1. First wave-dissipating holes 13 are provided on the wave-dissipating cross plate 11. Second wave-dissipating holes 14 are provided on the wave-dissipating longitudinal plate 12. Insertion rods 15 are provided on the fixing plate 1.

Sliding grooves 18 that cooperate with the sliding blocks 17 are provided on both sides of the clamping groove 7. An inclined surface 19 is provided at the top of the clamping block 9.

[0030] In this embodiment, both the fixing plate 1 and the slope protection plate 3 are precast concrete components. When splicing, the fixing plate 1 is installed on the slope of the slope protection by bolts. The slope protection plate 3 is installed on the fixing groove 2 of the fixing plate 1. Align the insertion groove of the slope protection plate 3 with the insertion rod 15 and install and fix it, which plays a role in fixing and positioning the slope protection plate 3. After the slope protection plates 3 are aligned in an array, taking the connecting blocks 4 and connecting grooves 5 of four slope protection plates 3 as a group, the connecting sleeve 6 is sleeved in the connecting groove 5. Through the inclined surface 19, the clamping block 9 is squeezed into the clamping groove 7. The clamping block 9 squeezes the clamping spring 8. When the clamping hole 10 is aligned with the clamping block 9, the clamping block 9 moves towards the clamping hole 10 under the elastic force of the clamping spring 8. The sliding block 17 moves along the sliding groove 18. The clamping block 9 extends into the clamping hole 10 to fix the position of the connecting sleeve 6, and further fixes the relative positions of the four slope protection plates 3. When the water flow impacts the wave-dissipating cross plate 11 and the wave-dissipating longitudinal plate 12, the wave-dissipating cross plate 11 and the first wave-dissipating holes 13, as well as the wave-dissipating longitudinal plate 12 and the second wave-dissipating holes 14, collide and impact with each other, making the waves fully break and eliminating part of the kinetic energy of the waves. Multiple groups of wave-dissipating cross plates 11 and wave-dissipating longitudinal plates 12 can be set to form stepped energy absorption to achieve the purpose of wave prevention and wave dissipation.

[0031] Please refer to Figure 5 , as an implementation method of the ecological mechanism: An ecological groove 20 is provided on the slope protection plate 3. An ecological mechanism is provided on the ecological groove 20. The ecological mechanism includes a layer of large-grained sand and gravel 21. A layer of fine sand 22 is provided on the large-grained sand and gravel layer 21. A planting soil layer 23 is provided on the fine sand layer 22. A layer of wet flower mud 24 is provided between the ecological groove 20 and the large-grained sand and gravel layer 21. A layer of small-grained sand and gravel 25 is provided on the planting soil layer 23. A plastic separation net 26 is provided on the small-grained sand and gravel layer 25.

[0032] More specifically, by arranging a large-particle sand and gravel layer 21, a fine sand layer 22, and a planting soil layer 23 in the ecological groove 20, it is convenient to plant plants, improving the ecological environment of the slope protection. The rainwater is stored through the water absorption of the wet flower mud layer 24. At the same time, the planting soil is isolated by the plastic partition net 26 and the small-particle sand and gravel layer 25 to prevent the planting soil from being washed away in case of heavy rain, providing favorable conditions for plant growth.

[0033] In summary, when the overall device is in use or operation: both the fixing plate 1 and the slope protection plate 3 are made of precast concrete components. When splicing, the fixing plate 1 is installed on the slope of the slope protection through bolts, and the slope protection plate 3 is installed in the fixing groove 2 of the fixing plate 1. Align the insertion groove of the slope protection plate 3 with the insertion rod 15 and install and fix it to play a role in fixing and positioning the slope protection plate 3. After the slope protection plates 3 are aligned in an array, take the connecting blocks 4 and connecting grooves 5 of four slope protection plates 3 as a group, sleeved the connecting sleeve 6 in the connecting groove 5, and through the inclined surface 19, squeeze the clamping block 9 into the clamping groove 7. The clamping block 9 squeezes the clamping spring 8. When the clamping hole 10 is aligned with the clamping block 9, the clamping block 9 moves towards the clamping hole 10 under the elastic force of the clamping spring 8, and the sliding block 17 moves along the sliding groove 18. The clamping block 9 extends into the clamping hole 10 to fix the position of the connecting sleeve 6, and further fixes the relative positions of the four slope protection plates 3. When the water flow impacts the wave-dissipating transverse plate 11 and the wave-dissipating longitudinal plate 12, the wave-dissipating transverse plate 11 and the first wave-dissipating holes 13, and the wave-dissipating longitudinal plate 12 and the second wave-dissipating holes 14 collide and impact with each other, causing the waves to break sufficiently and eliminating part of the kinetic energy of the waves. Multiple groups of wave-dissipating transverse plates 11 and wave-dissipating longitudinal plates 12 can be set to form a stepped energy absorption to achieve the purpose of wave prevention and wave dissipation.

[0034] By arranging a large-particle sand and gravel layer 21, a fine sand layer 22, and a planting soil layer 23 in the ecological groove 20, it is convenient to plant plants, improving the ecological environment of the slope protection. The rainwater is stored through the water absorption of the wet flower mud layer 24. At the same time, the planting soil is isolated by the plastic partition net 26 and the small-particle sand and gravel layer 25 to prevent the planting soil from being washed away in case of heavy rain, providing favorable conditions for plant growth.
