Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to an ecological slope protection structure for water conservancy projects. Background Art

[0002] A water conservancy project is a project used to control and allocate surface water and groundwater in nature, so that water resources can be fully utilized. As an important part of water conservancy projects, ecological slope protection mainly supports slopes or embankments by integrating basic knowledge of disciplines such as engineering mechanics, soil science, ecology, and botany, and forms a slope protection technology of a comprehensive slope protection system composed of plants or engineering and plants.

[0003] In a Chinese utility model patent with the publication number of CN220202589U, an ecological slope protection structure for water conservancy projects is disclosed, which includes a slope. The top side of the slope is assembled with uniformly paved slope protection bricks. The cross-section of the slope protection bricks is hexagonal, and each slope protection brick is connected. Six groups of threaded rods are fixedly installed on the bottom side of the slope protection bricks. Fourteen groups of opposite-positioned water flow holes are opened on the side walls of the slope protection bricks, and the water flow holes between the connected slope protection bricks are communicated. Through the setting of multiple groups of water flow holes, the rainwater inside the slope protection bricks can be quickly discharged, reducing the accumulation of rainwater, with high drainage efficiency and high practicability.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when there is no rainfall for a long time, it is easy to cause insufficient moisture in the soil layer of the slope, resulting in the plants on the slope lacking moisture and withering, and each slope protection brick is connected by a large number of threaded rods, which is inconvenient when the slope protection brick is damaged and needs to be replaced. Content of the Utility Model

[0005] In order to solve the above problems, the utility model provides an ecological slope protection structure for water conservancy projects.

[0006] The above technical object of the utility model is achieved through the following technical solutions: An ecological slope protection structure for water conservancy projects, including a slope body, the slope body is composed of a transverse slope and a slope, and a number of first main square pipes arranged along the width direction of the slope are arranged at intervals along the length direction of the slope on the slope, and a number of symmetrically arranged first branch pipes are communicated on both sides of the first main square pipe. Water absorption rope belts connected to each other are arranged in the first main square pipe and the first branch pipe. A second main square pipe is arranged on the first main square pipe, and a number of symmetrically arranged second branch pipes are communicated on both sides of the second main square pipe. A sealing plate is arranged at the lower end pipe orifice of the second main square pipe. One end of the water absorption rope belt in the first main square pipe extends into the water body, and the water absorption rope belt in the first branch pipe extends out of the orifice of the first branch pipe. A number of slope protection bricks are arranged between two adjacent first main square pipes, and the slope protection bricks between the two first main square pipes are arranged corresponding to the first branch pipes and are connected to each other. Soil layers are filled in the slope protection bricks.

[0007] By adopting the above technical solutions, the first main square pipe, the first branch pipe, the water absorption rope belt, the second main square pipe, the second branch pipe, and the slope protection bricks are provided. Plants are planted on the soil layer in the slope protection bricks. When there is no rainfall for a long time and the moisture in the soil layer is insufficient, the water absorption rope belt uses the capillary phenomenon to convey the moisture in the water body upward to ensure the moisture of the soil layer in the slope protection bricks, thereby ensuring the normal growth of plants. When encountering drought or the upstream closing the sluice gate resulting in less or dry water in the water body and the water absorption rope being unable to absorb water, the staff pours water into the upper end orifice of the second main square pipe, and the water flows along the second main square pipe and the second branch pipe into the soil layer in the slope protection bricks to supplement water for the plants.

[0008] Further, a water collection groove is opened along the length direction of the transverse slope on the transverse slope, and a notch is opened corresponding to the upper end orifice of the second square pipe on the water collection groove.

[0009] By adopting the above technical solutions, the water collection groove and the notch are provided, so that when the staff needs to pour water into the second main square pipe, only water needs to be poured into the water collection groove, and the water flows into the second main square pipe from the notch, which is more convenient; when there is a small amount of rainfall, the water on the transverse slope flows into the water collection groove, and then flows into the soil layer through the second main square pipe and the second branch pipe, and more water can be conveyed to the soil layer as much as possible.

[0010] Further, water flow grooves are opened on the upper and lower brick bodies of the slope protection bricks, and the water flow grooves of two vertically adjacent slope protection bricks are connected.

[0011] By adopting the above technical solutions, water flow grooves are opened on the upper and lower brick bodies of the slope protection bricks to prevent the slope protection bricks from blocking the water on the soil layer during the rainy season, resulting in too much water on and in the soil layer and causing the decay of plant roots.

[0012] Further, the edge of the water collection groove close to the slope protection brick is in contact with the bottom edge of the water flow groove.

[0013] By adopting the above technical solution, the edge of the water collecting tank adjacent to the slope protection brick is set to be in contact with the bottom edge of the water flow tank, facilitating the drainage of water in the water collecting tank.

[0014] Furthermore, a plurality of ground nails are arranged at intervals at the bottom of the first main square pipe, and clamping grooves are formed in the slope protection brick corresponding to the first branch pipe and the second branch pipe.

[0015] By adopting the above technical solution, ground nails and clamping grooves are provided. The first main square pipe is fixed on the slope through the ground nails, and then the clamping grooves on the slope protection brick are clamped on the second branch pipe and the first branch pipe, so that the slope protection brick is stably installed on the slope. There is no need to set threaded rods at the bottom of the slope protection brick to connect the slope protection brick with the slope. When the slope protection brick is damaged and needs to be replaced, it is convenient to remove the slope protection brick.

[0016] Furthermore, a connecting block with a length direction consistent with the length direction of the second main square pipe is arranged on the second main square pipe. A through hole is horizontally formed in the connecting block, and a through hole is formed in the slope protection brick corresponding to the through hole.

[0017] By adopting the above technical solution, the connecting block, the through hole and the through hole are provided. Bolts are passed through the through hole and the through hole and screwed into the nuts, so as to connect the connecting block with the slope protection bricks on both sides of the connecting block, increasing the stability of the installation of the slope protection bricks.

Plants are planted on the soil layer in the slope protection brick. When there is no rainfall for a long time and the water in the soil layer is insufficient, the water absorption rope belt uses the capillary phenomenon to convey the water in the water body upward, ensuring the moisture of the soil layer in the slope protection brick, so as to ensure the normal growth of plants. When encountering drought or the upstream closing the sluice gate resulting in less or dry water in the water body and the water absorption rope being unable to absorb water, the staff pours water into the upper end pipe orifice of the second main square pipe, and the water flows along the second main square pipe and the second branch pipe into the soil layer in the slope protection brick to supplement water for the plants;

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Such as Figures 1-5As shown in the figure, an ecological slope protection structure for water conservancy projects disclosed in an embodiment of the present application includes a slope body 10, a first main square pipe 20, a second main square pipe 30, and slope protection bricks 40. The slope body 10 is composed of a transverse slope 11 and a slope 12. A number of first main square pipes 20 are arranged at intervals along the length direction of the slope 12 on the slope 12. The first main square pipes 20 are arranged along the width direction of the slope 12. A number of symmetrically arranged first branch pipes 21 are communicated on both sides of the first main square pipe 20. The second main square pipe 30 is arranged on the first main square pipe 20. A number of symmetrically arranged second branch pipes 31 are communicated on both sides of the second main square pipe 30. A number of slope protection bricks 40 are arranged between two adjacent first main square pipes 20. The slope protection bricks 40 between the two first main square pipes 20 are arranged corresponding to the first branch pipes 21 and are connected to each other. The slope protection bricks 40 are filled with soil layers for planting plants.

[0030] Specifically, a number of ground nails 23 are arranged at intervals at the bottom of the first main square pipe 20, and the first main square pipe 20 is fixed on the slope 12 through the ground nails 23. The slope protection bricks 40 are provided with card slots 42 corresponding to the first branch pipes 21 and the second branch pipes 31. The card slots 42 on the slope protection bricks 40 are stuck on the second branch pipes 31 and the first branch pipes 21, so that the slope protection bricks 40 are stably installed on the slope 12. There is no need to set threaded rods at the bottom of the slope protection bricks 40 to connect the slope protection bricks 40 with the slope 12. When the slope protection bricks 40 are damaged and need to be replaced, it is convenient to remove the slope protection bricks 40. A connecting block 50 with a length direction consistent with the length direction of the second main square pipe 30 is arranged on the second main square pipe 30. A through hole 51 is horizontally opened on the connecting block 50. The slope protection bricks 40 are provided with through holes 43 corresponding to the through holes 51. Bolts are passed through the through holes 43 and the through holes 51 and screwed into nuts, so as to connect the connecting block 50 with the slope protection bricks 40 on both sides of the connecting block 50, and the stability of the installation of the slope protection bricks 40 is increased.

[0031] When setting, water absorption rope belts 22 connected to each other are arranged in both the first main square pipe 20 and the first branch pipes 21. One end of the water absorption rope belt 22 in the first main square pipe 20 extends into the water body, and the water absorption rope belt 22 in the first branch pipe 21 extends out of the pipe orifice of the first branch pipe 21. When there is no rainfall for a long time and the water in the soil layer is insufficient, the water absorption rope belt 22 uses the capillary phenomenon to convey the water in the water body upward, ensuring the moisture of the soil layer in the slope protection bricks 40, and thus ensuring the normal growth of plants. During production, connection ports for connecting the first branch pipes 21 can be opened on both sides of the first main square pipe 20 first, and then the water absorption rope belts 22 are passed through the first main square pipe 20. Subsequently, the water absorption rope belts 22 in the first branch pipes 21 are passed through the connection ports to be connected with the water absorption rope belts 22 in the first main square pipe 20, and then the first branch pipes 21 are welded at the interfaces of the first main square pipe 20.

[0032] When encountering drought or the upper stream closing the sluice, resulting in less or dry water in the water body and the water absorption rope being unable to absorb water, the staff will pour water into the upper end pipe orifice of the second main square pipe 30. The water flow flows along the second main square pipe 30 and the second branch pipe 31 into the soil layer in the slope protection brick 40 to supplement water for the plants. A sealing plate 32 is arranged at the lower end pipe orifice of the second main square pipe 30 to prevent the water flow in the second main square pipe 30 from flowing out of the lower end pipe orifice of the second main square pipe 30, and ensure that the water in the second main square pipe 30 flows into the second branch pipe 31.

[0033] During specific setting, a water collecting groove 13 is opened along the length direction of the cross slope 11 on the cross slope 11. A notch 14 is opened on the water collecting groove 13 corresponding to the upper end pipe orifice of the second square pipe. When the staff needs to pour water into the second main square pipe 30, it is only necessary to pour water into the water collecting groove 13, and the water flow flows into the second main square pipe 30 from the notch 14, which is more convenient; during light rainfall, the water on the cross slope 11 flows into the water collecting groove 13, and then flows into the soil layer through the second main square pipe 30 and the second branch pipe 31, so that more water can be conveyed to the soil layer as much as possible. Water flow grooves 41 are opened on the upper and lower side bricks of the slope protection brick 40. The height of the soil layer in the slope protection brick 40 is not higher than the bottom of the water flow groove 41. The water flow grooves 41 of two vertically adjacent slope protection bricks 40 are connected to prevent the slope protection brick 40 from blocking the water on the soil layer during the rainy season, resulting in excessive water on and in the soil layer and causing the roots of the plants to rot. The edge of the water collecting groove 13 adjacent to the slope protection brick 40 contacts the bottom edge of the water flow groove 41, which is convenient for draining the water in the water collecting groove 13 during heavy rain.

[0034] The working principle of an ecological slope protection structure for a water conservancy project in this embodiment is as follows: when the water content in the soil layer is insufficient due to long-term non-rainfall, the water absorption rope belt 22 uses the capillary phenomenon to convey the water in the water body upward to ensure the moisture of the soil layer in the slope protection brick 40, thereby ensuring the normal growth of plants; when encountering drought or the upper stream closing the sluice, resulting in less or dry water in the water body and the water absorption rope being unable to absorb water, the staff pours water into the water collecting groove 13. After the water flow flows along the water collecting groove 13, it flows into the upper end pipe orifice of the second main square pipe 30 through the notch 14, and the water flow flows along the second main square pipe 30 and the second branch pipe 31 into the soil layer in the slope protection brick 40 to supplement water for the plants.

[0035] The above is only the preferred implementation manner of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
