Description

Technical Field

[0001] The utility model relates to the technical field of ecological slope protection for river dams, in particular to an ecological slope protection structure for river dams. Background Technique

[0002] Ecological slope protection is a slope protection technology that comprehensively applies the basic knowledge of disciplines such as engineering mechanics, soil science, ecology, and botany to support slopes or side slopes, forming a comprehensive slope protection system composed of plants or engineering and plants. Usually, after excavating the side slope, by planting plants, the interaction between plants and rocks / soils (root anchoring effect) is used to protect and reinforce the surface layer of the slope, so that it can not only meet the requirements for the stability of the slope surface layer, but also restore the damaged natural ecological environment. It is an effective means of slope protection and slope fixation, so it is widely used in the construction of urban gardens and rivers. In the prior art, the hydrophobic performance of ecological slope protection is poor. Especially when the precipitation is large and the water absorption capacity of the soil reaches saturation and the slope protection can no longer absorb water, the rainwater cannot enter the soil, which will scour the surface of the ecological slope protection, seriously reducing the anti-scouring performance of the slope protection.

[0003] Therefore, an ecological slope protection structure for river dams has become an urgent problem to be solved in the whole society. Content of the Utility Model

[0004] To solve the above technical problems, the technical solution provided by the utility model is: an ecological slope protection structure for river dams, including a river dam, a plurality of rectangular grooves are opened at the top of the river dam, slope protection blocks are arranged inside the rectangular grooves, a combined hydrophobic pipeline device is arranged inside the river dam, a plurality of hydrophobic holes are arranged on the rectangular grooves, the combined hydrophobic pipeline device includes a water receiving tank, a connecting pipeline and a plurality of drainage pipelines, the top end of the connecting pipeline is communicated with the bottom end of the water receiving tank, and its bottom end is used to be communicated with the drainage pipelines, and the top opening of the water receiving tank is arranged below a plurality of hydrophobic holes;

[0005] Drainage grooves are arranged on both sides of the river dam in an inclined distribution, both ends of the drainage pipelines extend out of the river dam, and the extending ends are water outlets, and the water outlets on the drainage pipelines are arranged directly above the drainage grooves.

[0006] Furthermore, the periphery of the combined hydrophobic pipeline device is filled with a gravel filling layer, and a soil layer is filled on the top of the gravel filling layer.

[0007] Furthermore, a plurality of annular pipeline connectors are arranged between the drainage pipelines, a fixing plate is arranged between the plurality of annular pipeline connectors, fixing holes and fixing rods are opened on the fixing plate, the fixing rods are inserted into the fixing holes, and the bottom ends thereof are buried in the gravel filling layer for fixation.

[0008] The advantages of the utility model compared with the prior art are as follows:

[0009] The utility model combines multiple structures such as a river channel dam, a hydrophobic hole, a water receiving tank, a connecting pipe, and multiple drainage pipes to provide an ecological slope protection structure for a river channel dam with a hydrophobic function. Through the improved structure, the excess rainwater can be timely discharged to the outside of the river channel dam, improving the overall drainage performance of the river channel dam body and solving the problems such as poor hydrophobic performance existing in the slope protection structure of the river channel dam in the prior art.

[0010] By adopting the above structure, the utility model can timely discharge the excess rainwater from the slope protection of the river channel dam, avoiding phenomena such as erosion caused by the excess rainwater returning to the surface of the ecological slope protection.

[0011] The utility model adopts stepped slope protection blocks. When in use, when the water flow in the river channel scours the river embankment, part of the water flow impact force can be offset, thereby protecting the ecological slope protection and improving the stability of the dam body.

[0018] The following further describes the utility model in detail with reference to the drawings.

[0019] The utility model will be introduced in detail with reference to the drawings.

[0020] The utility model provides an ecological slope protection structure for a river channel dam during specific implementation, which includes a river channel dam 1. A plurality of rectangular grooves 2 are opened at the top of the river channel dam 1. A slope protection block 3 is arranged inside the rectangular groove 2. A combined hydrophobic pipeline device is arranged inside the river channel dam 1. A plurality of hydrophobic holes 4 are arranged on the rectangular groove 2. The combined hydrophobic pipeline device includes a water receiving tank 5, a connecting pipeline 6 and a plurality of drainage pipelines 7. The top end of the connecting pipeline 6 is communicated with the bottom end of the water receiving tank 5, and its bottom end is used for communicating with the drainage pipeline 7. The opening at the top end of the water receiving tank 5 is arranged below the plurality of hydrophobic holes 4;

[0021] Drainage grooves 8 with an inclined distribution are arranged on both sides of the river channel dam 1. Both ends of the drainage pipeline 7 extend out of the river channel dam 1, and the extending ends are water outlets 9. The water outlets 9 on the drainage pipeline 7 are arranged directly above the drainage grooves 8.

[0022] Embodiment 1:

[0023] When the utility model is in use, when there is a lot of rain, the rain falls into the slope protection block 3. When the soil in the slope protection block 3 is saturated with water absorption and cannot absorb water anymore, the rainwater falls from the hydrophobic holes 4 on the rectangular groove 2 into the water receiving tank 5 below, and then the rainwater flows into the drainage pipeline 7 along the connecting pipeline 6. Finally, it is discharged from the water outlet 9 on the drainage pipeline 7 into the drainage groove 8, and the rainwater flows out of the ecological slope protection along the drainage groove 8. Through the above structure, the hydrophobic function inside the ecological slope protection is improved, the phenomenon that the surface of the ecological slope protection is washed by too much rainwater is avoided, the overall drainage performance of the river channel dam 1 is improved, the structure is simple, and the hydrophobic performance is good.

[0024] Embodiment 2:

[0025] The surrounding of the combined hydrophobic pipeline device is filled with a gravel filling layer 10, and a soil layer 11 is filled at the top of the gravel filling layer 10. A plurality of annular pipeline connectors 12 are arranged between the drainage pipelines 7, and a fixing plate 13 is arranged between the plurality of annular pipeline connectors 12. A fixing hole 14 and a fixing rod 15 are opened on the fixing plate 13, and the fixing rod 15 is inserted into the fixing hole 14, and its bottom end is buried in the gravel filling layer 10 to achieve fixation.

[0026] The combined hydrophobic pipeline device is supported by the above-mentioned gravel filling layer, which increases the stability of the combined hydrophobic pipeline device inside. A plurality of annular pipeline connectors 12 are arranged between the drainage pipelines 7, which improves the structural strength and stability of the connecting pipeline.

[0027] Except for the gravel filling layer 10 and the soil layer 11, the other positions are made of concrete.

[0028] To facilitate hydrophobicity, the top end of the water receiving tank 5 is inclined to be in contact with the bottom end of the rectangular tank body 2 in the river dam 1.

[0029] To prevent rainwater from overflowing, a baffle 16 extends upward from the outside of the drainage groove 8.

[0030] Embodiment 3:

[0031] A slope protection block 17 is provided at the bottom end of the river dam 1, and the slope protection block 17 is arranged in a stepped structure.

[0032] The utility model adopts a stepped slope protection block. When in use, when the water flow in the river scours the river embankment, part of the water flow impact force can be offset, so as to protect the ecological slope protection and improve the stability of the dam body.

[0033] As a further elaboration of the utility model, ecological green plants are planted in the slope protection block 3. While enhancing the overall structural strength of the slope protection, the aesthetics of the entire ecological slope protection is also increased.
