Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a slope protection method for river embankment design in water conservancy engineering. Background Technology

[0002] Chinese patent CN219175141 U discloses a riverbank protection brick, belonging to the field of slope protection technology. This brick includes a brick body with slots a on both the front and rear sides, forming engaging parts a and b on the same sides. A slot b is located on the left side of the brick body, and an engaging part c mates with slot b on the right side. A groove a is located at the top edge of the brick body, with a channel through the brick body formed on the bottom wall of the groove a. A stepped hole is also located at the top of the brick body, with a detachable fastener inside. This design solves the problem of existing slope protection bricks where the tight fit makes it difficult to fill the joints with concrete, leading to detachment from the riverbank over time and preventing the bricks from anchoring to the riverbed soil, thus causing detachment during use.

[0003] During the application process, the applicant discovered that the above application has defects in its use. After the slope protection bricks are installed, the application uses fasteners to clamp the slope protection bricks. However, the fasteners need to be installed manually by construction workers, which greatly prolongs the construction period of the entire river slope protection brick project and reduces construction efficiency. Moreover, the fasteners have a complex structure, which is not only not conducive to construction, but also not conducive to large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection for river embankments in water conservancy engineering design, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A type of slope protection for river embankments in hydraulic engineering design, comprising:

[0007] The slope protection block has an upper protrusion on the top and a lower groove corresponding to the upper protrusion on the bottom. The slope protection block has a side protrusion on one side and a side groove corresponding to the side protrusion on the other side. The slope protection block has slots at the four corners and slots at the bottom of the slots.

[0008] A positioning block is inserted into the slot, and a plug is fixedly connected to the bottom of the positioning block, which is inserted into the slot.

[0009] Preferably, both the slope protection block and the positioning block are made of concrete.

[0010] Preferably, the upper protrusion, lower groove, side protrusion, and side groove are all trapezoidal in shape.

[0011] Preferably, the bottom of the slope protection block has multiple parallel sinkholes.

[0012] Preferably, the slots at the four corners of the adjacent slope protection form a cross groove, the insert is arranged in a cross shape, and the side wall of the insert is arranged in a sharp edge.

[0013] Preferably, a chopping block is fixedly connected to the bottom of the insert block, and the bottom of the chopping block is set with a sharp edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting up slope protection blocks and positioning blocks, allows users to install the slope protection blocks on the riverbank, interlocking them together. Then, positioning blocks are inserted into the slots and grooves between adjacent slope protection blocks. With prolonged use, the riverbank soil seeps into the settling trench, increasing the tightness of the connection between the slope protection blocks and the riverbank. Furthermore, as river water seeps into the slope protection blocks, the flowing water follows the edges of the insert and split blocks, impacting the soil at the bottom of the positioning blocks, causing them to gradually sink into the riverbank soil. As the positioning blocks gradually sink, their fixation to the slope protection blocks improves, effectively increasing the stability of the slope protection blocks and preventing them from shifting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] Please see Figure 1 - Figure 5 As shown, a type of revetment for river embankments in hydraulic engineering design includes:

[0025] The slope protection block 1 has an upper protrusion 3 on its top and a lower groove 4 corresponding to the upper protrusion 3 on its bottom. The slope protection block 1 has a side protrusion 5 on one side and a side groove 6 corresponding to the side protrusion 5 on the other side. The slope protection block 1 has slots 8 at its four corners and slots 9 at the bottom of the slots 8.

[0026] Positioning block 2 is inserted into the slot 8. The bottom of positioning block 2 is fixedly connected to insert block 21, which is inserted into slot 9.

[0027] The upper protrusion 3 of one slope protection block 1 can be inserted into the lower groove 4 of another slope protection block 1, and the side protrusion 5 of one slope protection block 1 can be inserted into the side groove 6 of another slope protection block 1. Multiple slope protection blocks 1 laid on the riverbank are thus connected to each other to form a whole, preventing individual slope protection blocks 1 from being washed away by the river water. After the slope protection blocks 1 are installed, the positioning block 2 is inserted into the temporal part of the slot 9. The positioning block 2 is used to increase the tightness of the connection between the slope protection block 1 and the riverbank, further preventing the slope protection block 1 from moving.

[0028] Both the slope protection block 1 and the positioning block 2 are made of concrete and are integrally molded using a mold.

[0029] The upper protrusion 3, lower groove 4, side protrusion 5 and side groove 6 are all trapezoidal. The upper protrusion 3 corresponds to the lower groove 4, and the side protrusion 5 corresponds to the side groove 6. The groove is slightly larger than the protrusion. The gap between the groove and the protrusion is controlled at 1-3 mm to facilitate the construction personnel to assemble the slope protection block 1.

[0030] The bottom of the slope protection block 1 is provided with multiple parallel sinking grooves 7. The sinking grooves 7 can increase the roughness of the bottom of the slope protection block 1, prevent the slope protection block 1 from shifting on the riverbank slope. At the same time, during long-term use, the soil from the riverbank slope will enter the sinking grooves 7, thereby increasing the tightness of the connection between the slope protection block 1 and the riverbank slope.

[0031] The slots 9 at the four corners of the adjacent slope protection blocks 1 form a cross groove, the insert 21 is arranged in a cross shape, and the side wall of the insert 21 is arranged in a sharp edge.

[0032] The water in the river will flow through the gaps between the revetment blocks 1 and come into contact with the riverbank. Since the insert blocks 21 are arranged in a cross shape, the water will be separated by the front of the insert blocks 21 after it comes into contact with them, and then impact the slope soil at the bottom of the insert blocks 21. As the soil is washed away, the insert blocks 21 gradually sink into the riverbank under the action of gravity. After the insert blocks 21 are inserted into the soil, the connection between the revetment blocks 1 and the riverbank will be strengthened, further preventing the revetment blocks 1 from shifting during use.

[0033] Example 2:

[0034] Please see Figure 1 - Figure 5 As shown, a type of revetment for river embankments in hydraulic engineering design includes:

[0035] The slope protection block 1 has an upper protrusion 3 on its top and a lower groove 4 corresponding to the upper protrusion 3 on its bottom. The slope protection block 1 has a side protrusion 5 on one side and a side groove 6 corresponding to the side protrusion 5 on the other side. The slope protection block 1 has slots 8 at its four corners and slots 9 at the bottom of the slots 8.

[0036] Positioning block 2 is inserted into the slot 8. The bottom of positioning block 2 is fixedly connected to insert block 21, which is inserted into slot 9.

[0037] The upper protrusion 3 of one slope protection block 1 can be inserted into the lower groove 4 of another slope protection block 1, and the side protrusion 5 of one slope protection block 1 can be inserted into the side groove 6 of another slope protection block 1. Multiple slope protection blocks 1 laid on the riverbank are thus connected to each other to form a whole, preventing individual slope protection blocks 1 from being washed away by the river water. After the slope protection blocks 1 are installed, the positioning block 2 is inserted into the temporal part of the slot 9. The positioning block 2 is used to increase the tightness of the connection between the slope protection block 1 and the riverbank, further preventing the slope protection block 1 from moving.

[0038] Both the slope protection block 1 and the positioning block 2 are made of concrete and are integrally molded using a mold.

[0039] The upper protrusion 3, lower groove 4, side protrusion 5 and side groove 6 are all trapezoidal. The upper protrusion 3 corresponds to the lower groove 4, and the side protrusion 5 corresponds to the side groove 6. The groove is slightly larger than the protrusion. The gap between the groove and the protrusion is controlled at 1-3 mm to facilitate the construction personnel to assemble the slope protection block 1.

[0040] The bottom of the slope protection block 1 is provided with multiple parallel sinking grooves 7. The sinking grooves 7 can increase the roughness of the bottom of the slope protection block 1, prevent the slope protection block 1 from shifting on the riverbank slope. At the same time, during long-term use, the soil from the riverbank slope will enter the sinking grooves 7, thereby increasing the tightness of the connection between the slope protection block 1 and the riverbank slope.

[0041] The slots 9 at the four corners of the adjacent slope protection blocks 1 form a cross groove. The insert block 21 is arranged in a cross shape, and the side wall of the insert block 21 is set with a sharp edge. A splitting block 22 is fixedly connected to the bottom of the insert block 21, and the bottom of the splitting block 22 is set with a sharp edge.

[0042] The water in the river will flow along the gaps between the slope protection blocks 1 and come into contact with the riverbank. Since the insert blocks 21 are arranged in a cross shape, the water will be separated by the sharp edge of the insert blocks 21 after contacting them, and then impact the slope soil at the bottom of the insert blocks 21. As the soil is washed away, the insert blocks 21 and the split blocks 22 gradually sink into the riverbank under the action of gravity. Since the lower end of the split blocks 22 is set with a sharp edge, it can be inserted into the soft soil more easily. After the insert blocks 21 and the split blocks 22 are inserted into the soil, the connection between the slope protection blocks 1 and the riverbank will be tighter, further preventing the slope protection blocks 1 from shifting during use.

[0043] During use, construction workers can first install the slope protection block 1 on the riverbank slope and make multiple slope protection blocks 1 stably connected together. After the slope protection block 1 is installed, the positioning block 2 is then inserted between the adjacent slope protection blocks 1, so that the slope protection block 1 is stably connected to the riverbank slope, effectively preventing the slope protection block 1 from sliding and displacing during long-term use, and effectively improving the service life and effect of the slope protection block 1.
