Description

Technical Field

[0001] The present application relates to the technical field of dam body slope protection structures, and in particular to a dam body structure for preventing soil and water loss on a slope. Background Art

[0002] An earth dam, also known as an earth-rock dam, is a type of dam that is commonly found on both sides of a river. An earth dam has the functions of storing water, rationally controlling and allocating water, and preventing and discharging flood water.

[0003] The earth dam structure is the most primitive dam structure, which is mainly made of soil and gravel. However, because of this, the structure of the earth dam is not stable, especially the slope of the dam body, which has a large slope and is prone to soil erosion and even landslides under long-term erosion by rain and river water, thus destroying the dam structure. Therefore, slope protection projects should be implemented on the dam slope to increase the stability of the dam slope and the dam structure to prevent the dam from being damaged.

[0004] In the prior art, there is a river channel ecological slope protection structure for water conservancy construction, with announcement number CN218175740U, which lays a stone layer on the slope of the dam body, and lays a concrete inclined layer on the stone layer, and a positioning pin is arranged on the concrete inclined layer, and the positioning pin is located in the dam body. A top layer of concrete is laid on the top of the dam body and a wedge-shaped platform is laid on the bottom of the dam body, and a plurality of green planting areas are arranged on the concrete inclined layer, so as to achieve the purpose of ecological slope protection on the slope of the dam body. However, due to the complex structure of the dam body slope protection structure in the prior art, the slope protection project is also complex to implement and the project period is long, and the green planting area is arranged on the concrete inclined layer, which is blocked by the concrete inclined layer and the stone layer, which will inhibit the roots of vegetation from taking root in the soil in the dam body, which will be detrimental to the good growth of vegetation in the long run. Utility Model Content

[0005] In order to improve the defects of the existing dam slope protection structure, which is complicated to implement and has a long engineering period, and the vegetation growth is restricted, which is not conducive to the good growth of vegetation in the long term, the present application provides a dam structure for preventing soil erosion on the slope.

[0006] This application provides a dam structure for preventing soil erosion on a slope, which adopts the following technical solution:

[0007] A dam structure for preventing soil erosion on a slope comprises a dam body, wherein a plurality of slope protection bricks are laid on the slope of the dam body, wherein the plurality of slope protection bricks are distributed in an array on the slope of the dam body, wherein the lower portion of the slope protection bricks is located within the dam body, and the upper portion of the slope protection bricks is located outside the dam body, wherein a planting cavity for planting green plants is provided inside the slope protection bricks, wherein the planting cavity runs through the upper and lower portions of the slope protection bricks, and adjacent slope protection bricks are arranged at intervals to form a flow channel on the slope of the dam body.

[0008] By adopting the above technical solution, the structure of the dam slope protection of the present application is relatively simple, and it is only necessary to lay slope protection bricks in order on the dam slope surface. Therefore, the dam slope protection project will be relatively simple to implement and the dam slope protection project cycle will be short. The slope protection bricks are provided with planting cavities for planting green plants. The green plants are directly planted on the dam slope surface, and the soil brought by the dam body is used. Therefore, the growth of green plants will not be restricted, which will be conducive to the good growth of vegetation in the long run. The flow channels formed on the dam slope surface by setting intervals between adjacent slope protection bricks can be used for rapid drainage of the dam slope surface on rainy days to prevent rainwater from gathering in the planting cavities provided in the slope protection bricks, causing the green plants to die.

[0009] Optionally, a layer of concrete is poured along the flow channel on the slope of the dam body to form a concrete layer, and the surface height of the concrete layer is lower than the upper height of the slope protection bricks.

[0010] By adopting the above technical solution, setting a concrete layer can not only reinforce the slope bricks and the dam slope, but also prevent rainwater and river water from directly eroding the flow channel and causing damage to the flow channel.

[0011] Optionally, a pebble layer is laid between the concrete layer and the slope of the dam body, the pebble layer and the slope of the dam body are embedded in each other, and the concrete layer and the pebble layer are also embedded in each other.

[0012] By adopting the above technical solution, the pebble layer can improve the bonding degree between the concrete layer and the slope of the dam body, making the concrete layer more stable along the flow channel on the slope of the dam body.

[0013] Optionally, the outer circle of the slope protection brick is configured as a regular hexagonal structure, and the planting cavity inside the slope protection brick is also configured as a regular hexagonal structure.

[0014] By adopting the above technical solution, the slope protection bricks with regular hexagonal structure will have a more stable structure and can be laid more orderly on the slope of the dam body.

[0015] Optionally, a drainage hole is provided on the side wall of the slope protection brick on the side with a lower height, and the height of the drainage hole is higher than the surface height of the concrete layer.

[0016] By adopting the above technical solution, the drainage holes are provided to discharge the excessive water in the slope protection bricks, so as to prevent the excessive accumulation of water in the slope protection bricks and cause the death of green plants.

[0017] Optionally, a geotextile layer is provided in the drainage hole, and the geotextile layer is folded along the hole wall of the drainage hole to form a folded edge, and the folded edge is glued and connected to the hole wall of the drainage hole.

[0018] By adopting the above technical solution and utilizing the good water permeability of the geotextile layer, the soil in the slope protection bricks can be prevented from being lost from the drainage holes along with the water.

[0019] Optionally, a plurality of grooves are distributed along the circumferential direction at positions corresponding to the concrete layer on the outer wall of the slope protection brick, and the concrete layer is poured into the grooves.

[0020] By adopting the above technical solution, the concrete layer is poured into the groove on the outer wall of the slope protection brick, which can improve the bonding degree between the concrete layer and the slope protection brick, which is more conducive to reinforcing the slope protection brick.

[0021] Optionally, a portion of the outer wall of the slope protection brick located inside the dam body has a plurality of edges distributed along the circumferential direction.

[0022] By adopting the above technical solution, the edges arranged on the outer side walls of the slope protection bricks can enhance the pull-out resistance of the slope protection bricks on the slope surface of the dam body, making the slope protection bricks more stable on the slope surface of the dam body.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. The structure of the dam slope protection of the present application is relatively simple. It only requires laying slope protection bricks in sequence on the dam slope surface and laying a pebble layer along the flow channel and then pouring a concrete layer. The dam slope protection project will be relatively simple to implement and the dam slope protection project cycle is short. The planting cavity set in the slope protection bricks is used to plant green plants. The green plants are directly planted on the dam slope surface, using the soil brought by the dam body, so the growth of green plants will not be restricted, which will be conducive to the good growth of vegetation in the long run.

[0025] 2. The flow channel formed between adjacent slope protection bricks can be used to quickly drain the dam slope surface on rainy days to prevent rainwater from gathering in the planting cavity inside the slope protection bricks and causing the death of green plants.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a dam structure for preventing soil erosion on a slope, referring to Figure 1 and Figure 2 The dam structure for preventing soil erosion on the slope is to lay slope protection bricks 2 on the slope of the dam body 1. The slope protection bricks 2 are regular hexagonal structures and are distributed in an array on the slope of the dam body 1. However, adjacent slope protection bricks 2 have the same spacing. The lower part of the slope protection brick 2 (accounting for half of the height of the slope protection brick 2) is buried in the dam body 1, while the upper part of the slope protection brick 2 (accounting for half of the height of the slope protection brick 2) is located outside the dam body 1. Figure 3 In order to make the slope protection bricks 2 more stable on the slope of the dam body 1 and improve the effect of the slope protection structure of the dam body 1, a plurality of outwardly protruding edges 7 are integrally formed and distributed on the lower outer wall of the slope protection bricks 2, that is, the part buried in the dam body 1, so as to increase the pull-out resistance of the slope protection bricks 2 on the slope of the dam body 1. The interior of the slope protection bricks 2 has a planting cavity 21 with a regular hexagonal structure. The planting cavity 21 can be used to plant green plants to improve the ecological environment effect of the slope of the dam body 1. It should be noted here that the green plants are directly planted on the slope of the dam body 1 in the planting cavity 21 of the slope protection bricks 2, using the soil brought by the dam body 1, so the growth of the green plants will not be restricted, and the roots of the green plants can continue to take root downward, which will be conducive to the good growth of the green plants in the long run.

[0032] Reference Figure 1 and Figure 2 Since there is a spacing between adjacent slope protection bricks 2, a flow channel 3 will be formed on the slope of the dam body 1 to allow the slope of the dam body 1 to drain quickly on rainy days, and to prevent rainwater from gathering in the planting cavity 21 provided in the slope protection bricks 2, causing the green plants to die. In order to reduce the scouring of the flow channel 3, that is, the slope of the dam body 1 by rainwater, a layer of pebbles 5 can be first laid in the flow channel 3, and then a layer of concrete 4 can be poured on the pebble layer 5, but the surface height of the concrete layer 4 is lower than the upper height of the slope protection bricks 2. It should be noted that the pebble layer 5 is partially embedded in the slope of the dam body 1, and the pebble layer 5 is also partially embedded in the concrete layer 4. The purpose of setting the pebble layer 5 is to improve the bonding degree between the concrete layer 4 and the slope of the dam body 1, so that the concrete layer 4 is more stable on the slope of the dam body 1, and the concrete layer 4 can not only reinforce the slope protection bricks 2 and the slope of the dam body 1, but also prevent rainwater and river water from directly scouring the flow channel 3 and causing damage to the flow channel 3.

[0033] Reference Figure 3Grooves 23 are provided on the six upper outer walls of the slope protection bricks 2 at positions corresponding to the concrete layer 4. During the pouring of the concrete layer 4 in the flow channel 3, the concrete will be poured into the grooves 23, thereby increasing the bonding degree between the concrete layer 4 and the slope protection bricks 2, making the slope protection bricks 2 more stable on the slope surface of the dam body 1, thereby making the slope protection structure of the dam body 1 more effective.

[0034] Reference Figure 3 A drainage hole 22 is provided on the side wall of the lower side of the slope protection brick 2. The height of the drainage hole 22 is higher than the surface height of the concrete layer 4, so that the excessive water in the slope protection brick 2 can be discharged in time to prevent the excessive accumulation of water in the slope protection brick 2 and the death of green plants. In addition, a geotextile layer 6 is provided in the drainage hole 22. The four edges of the geotextile layer 6 are folded to form a folded edge. The folded edge is glued and fixed to the hole wall of the drainage hole 22, so that the geotextile layer 6 is fixed in the drainage hole 22. The good water permeability of the geotextile layer 6 can prevent the soil in the slope protection brick 2 from flowing out of the drainage hole 22 along with the water.

[0035] The implementation principle of the dam structure for preventing soil erosion on a slope according to the embodiment of the present application is as follows: the structure of the slope protection of the dam body 1 of the present application is relatively simple. It only needs to lay the slope protection bricks 2 in order on the slope of the dam body 1 and lay the cobblestone layer 5 along the flow channel 3 and then pour the concrete layer 4. The slope protection project of the dam body 1 will be relatively simple to implement and the slope protection project period of the dam body 1 will be short. The planting cavity 21 provided in the slope protection bricks 2 is used to plant green plants. The green plants are directly planted on the slope of the dam body 1, and the soil brought by the dam body 1 is used. Therefore, the growth of green plants will not be restricted, which will be conducive to the good growth of vegetation in the long run. The flow channels 3 formed on the slope of the dam body 1 are arranged at intervals between adjacent slope protection bricks 2, which can be used for rapid drainage of the slope of the dam body 1 on rainy days to prevent rainwater from gathering in the planting cavity 21 provided in the slope protection bricks 2, causing the green plants to die.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
