Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a slope protection structure for preventing soil erosion. Background Technology

[0002] Currently, slope protection measures against soil erosion mainly include engineering slope protection, vegetation slope protection, and flexible protective netting. While existing engineering slope protection measures (such as concrete facing walls and retaining walls) can resist erosion to a certain extent, the rigid materials obstruct the natural connection between the soil and vegetation, easily leading to concentrated runoff erosion. This is especially true for slopes with loose soil, where rainwater infiltration softens the soil, and the erosion by water flow can easily destabilize the slope structure, causing landslides. Therefore, a slope protection structure that can stably prevent soil erosion is needed. Utility Model Content

[0003] In view of the technical problems existing in the prior art, the purpose of this utility model is to provide a slope protection structure that prevents soil erosion, which is conducive to rainwater infiltration, slows down the erosion of the slope by water flow, and can prevent the slope from becoming unstable and collapsing.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a slope protection structure for preventing soil erosion, comprising a drainage structure, slope protection bricks, and a water storage tank. The drainage structure includes a diversion channel, a filter screen, and a drainage pipe. The diversion channel is located at the top of the slope, the filter screen is located at the opening of the diversion channel, and the drainage pipe connects the diversion channel and the water storage tank. The drainage pipe is used to transport the water flow in the diversion channel to the water storage tank. The slope protection bricks include grid beams and protective grids. The grid beams are laid on the slope surface, and the grid beams are fixedly connected with anchor piles that penetrate deep into the interior of the slope.

[0005] With this structure, the diversion channel is designed with an inward concave surface, allowing surface runoff from the top of the slope to preferentially flow into the channel. The filter screen is used to filter impurities in the water flow, preventing blockage of the drainage structure. This allows the water to be quickly discharged into the reservoir through the drainage structure, slowing down water erosion. In addition, the anchor piles are anchored into the slope base, which can enhance the overall stability of the structure. The geometric structure of the protective grid disperses the impact force of rainwater to reduce soil erosion, further reducing the risk of structural instability and collapse.

[0006] As a preferred option, the water storage tank is located at the toe of the slope, with one end of the drain pipe connected to the bottom of the diversion channel and the other end connected to the inlet of the water storage tank.

[0007] As a preferred option, the slope protection bricks are in multiple pieces, distributed on the slope surface between the diversion channel and the slope toe.

[0008] As a preferred option, the top of the reservoir is flush with the bottom of the lowest slope protection bricks.

[0009] As a preferred option, the reservoir has a rectangular cross-section that extends along the slope toe.

[0010] As a preferred option, the protective grid is composed of multiple diamond-shaped splicing units, which are fixedly connected to the inner side of the grid beam.

[0011] As a preferred option, the rhomboid splicing unit is a hollow rhomboid structure with grid strips inside. Each end of the grid strip is connected to two opposite corners to form two triangular hollows. There are five rhomboid splicing units in each brick slope, which are distributed in a five-point plum blossom pattern.

[0012] As a preferred embodiment, several fixed beams are connected between two adjacent rhomboid splicing units and between the rhomboid splicing unit and the inner wall of the grid beam.

[0013] As a preferred option, the bottom of the anchor pile is wedge-shaped.

[0014] As a preferred embodiment, the drainage channel is truncated cone-shaped, with the opening radius at the top of the drainage channel being larger than the bottom radius.

[0015] In summary, this utility model has the following advantages:

[0016] (1) The drainage channel can divert most of the rainwater on the top of the slope to the storage tank. The protective grid structure of the slope protection bricks is conducive to rainwater infiltration, which can reduce the erosion of the slope by water flow and reduce the impact of water flow. It is also conducive to the growth of vegetation on the slope.

[0017] (2) By fixing the slope protection bricks with anchor piles, the stability of the entire protection structure can be further improved, and instability and collapse can be effectively prevented.

[0018] (3) The drainage structure intercepts impurities through the filter screen, which prevents large impurities from clogging the drainage structure and helps to ensure smooth drainage.

[0019] (4) The reservoir located at the foot of the slope can store water during heavy rains and supply water during droughts, thus improving the local ecosystem. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-3 As shown, a slope protection structure for preventing soil erosion includes a drainage structure, slope protection bricks, and a water storage tank. The drainage structure includes a diversion channel, a filter screen, and a drainage pipe. The diversion channel is located at the top of the slope, the filter screen is located at the opening of the diversion channel, and the drainage pipe connects the diversion channel and the water storage tank. The drainage pipe is used to transport the water flow in the diversion channel to the water storage tank. The slope protection bricks include grid beams and protective grids. The grid beams are laid on the slope surface and are fixedly connected to anchor piles, which penetrate deep into the interior of the slope.

[0027] Specifically, the reservoir is located at the toe of the slope, with one end of the drain pipe connected to the bottom of the diversion channel and the other end connected to the inlet of the reservoir. Rainwater flows into the reservoir through the diversion channel and drain pipe, and the reservoir can be connected to the local drainage system through drainage pipes. When there is too much rainwater and the reservoir is full, it is discharged.

[0028] Specifically, the slope protection bricks consist of multiple bricks distributed on the slope surface between the drainage channel and the slope toe. The slope protection bricks are generally square in shape and are closely arranged along the slope surface. The inner side of the slope protection bricks has a hollow structure to reduce the impact on the vegetation on the slope surface and maintain the ecological environment of the slope.

[0029] Specifically, the top of the reservoir is flush with the bottom of the lowest slope protection bricks.

[0030] Specifically, the reservoir has a rectangular cross-section that extends along the slope toe. This facilitates the management and maintenance of the reservoir and maximizes the use of space at the slope toe.

[0031] Specifically, the protective grid is composed of multiple diamond-shaped splicing units, which are fixedly connected to the inner side of the grid beams. The diamond-shaped splicing units make the slope protection brick structure more stable.

[0032] Specifically, the rhomboid splicing unit is a hollow rhomboid structure with internal grid strips. Each end of the grid strip is connected to two opposite corners to form two triangular openings. There are five rhomboid splicing units in each brick slope, distributed in a five-point plum blossom pattern.

[0033] Specifically, there are several fixed beams connecting two adjacent rhomboid splicing units and between the rhomboid splicing unit and the inner wall of the grid beam.

[0034] Specifically, the bottom of the anchor pile is wedge-shaped. The anchor pile is installed vertically at a certain angle to the slope surface. The upper end of the anchor pile is fixedly connected to the well beam grid, and the lower end is inserted into the slope for installation.

[0035] Specifically, the drainage channel is truncated cone-shaped, and the opening radius at the top of the drainage channel is larger than the bottom radius.

[0036] During periods of continuous rainfall, the drainage structure rapidly diverts runoff through diversion channels. After impurities are intercepted by a filter screen, the water flows through a drainage pipe into a reservoir, preventing continuous hydraulic impact on the slope. The slope protection bricks are fixed by anchor piles, and the water flow is dispersed by protective grids, reducing most of the topsoil loss. During periods of prolonged drought, rainwater stored in the reservoir during the rainy season can be used to re-irrigate the slope vegetation or surrounding plants using commercially available irrigation devices.

[0037] The above embodiments are preferred embodiments of the utility model, but the implementation of the utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the utility model shall be considered equivalent substitutions and shall be included within the protection scope of the utility model.
