Description

Technical Field

[0001] This utility model relates to the field of flood control technology in water conservancy projects, and in particular to a flood control slope protection device for water conservancy projects. Background Technology

[0002] In water conservancy projects, in order to reduce soil erosion on slopes, slope protection devices are generally set up on slopes. The slope protection net structure is used to lock the soil and plant vegetation on the slope to reduce soil erosion. However, the existing flood control slope protection devices have many shortcomings, such as: (1) Most slope protection devices can only prevent soil erosion or provide structural support, lacking comprehensive protection functions; (2) When facing heavy rainfall and floods, the protected slope is prone to landslides and collapses, resulting in poor protection effect; (3) Rainwater is easy to penetrate and erode the slope, resulting in serious soil erosion; (4) After the vegetation is planted, it is easy to be washed away by rainwater due to the lack of effective fixing measures, affecting the ecological slope protection effect.

[0003] Therefore, there is an urgent need to further improve the existing flood control and slope protection devices. Utility Model Content

[0004] The purpose of this utility model is to provide a flood control and slope protection device for water conservancy projects, which to a certain extent solves the problems of single function, insufficient protection, easy soil erosion and difficulty in fixing vegetation in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flood control slope protection device for water conservancy projects includes a protective slope installed above a riverbank. The slope surface of the protective slope is provided with a permeable layer. A slope protection foundation layer formed by permeable concrete is fixed above the permeable layer. The slope protection foundation layer forms a plurality of filling cavities. Each filling cavity is provided with a plastic mesh and planting soil covering the plastic mesh. The plastic mesh forms planting cavities for planting slope protection vegetation. A permeable channel is provided inside the riverbank. One end of the permeable channel is connected to the lower part of the permeable layer, and the other end of the permeable channel is connected to the river channel.

[0007] Furthermore, the slope toe of the protective slope is provided with a protective stone layer distributed along the riverbank, and a reinforced retaining wall is provided on the side of the protective stone layer closest to the river channel.

[0008] Furthermore, the slope protection base layer is provided with a protruding frame distributed around the outer periphery of the filling cavity, and a water guide groove is formed between the frames corresponding to two adjacent filling cavities.

[0009] Furthermore, the upper part of the protective stone layer is provided with drainage ditches distributed along the river channel. One side of the drainage ditch is connected to the water guide channel, and the other side of the drainage ditch is connected to a drainage pipe facing the river channel.

[0010] Furthermore, the filling cavities are square in shape and are distributed in a matrix on the slope protection foundation layer.

[0011] Furthermore, the filling cavity is fixed with a reinforced mac mat covering the surface of the planting soil.

[0012] Furthermore, the slope protection foundation layer is provided with anchoring holes, and anchoring rods inserted into the slope protection are installed in the anchoring holes.

[0013] Furthermore, the anchor rods are distributed perpendicularly to the slope surface of the protective slope.

[0014] Furthermore, the plastic mesh is a geocell with a three-dimensional mesh structure formed from HDPE sheet material.

[0015] Furthermore, the permeable channel includes a permeable mesh formed by a geonet and crushed stone filled inside the permeable mesh; the permeable layer is made of sand and gravel.

[0016] Compared with the prior art, this utility model provides a flood control and slope protection device for water conservancy projects, which has the following beneficial effects:

[0017] This invention, by arranging plastic mesh within the filling cavity of the slope protection base layer, effectively fixes vegetation and retains soil, preventing soil erosion. The combination of a permeable layer and permeable channels allows for the rapid drainage of infiltrated rainwater into the river channel, preventing prolonged soaking of the slope and improving the protective effect. Furthermore, the use of permeable concrete in the slope protection base layer allows some rainwater from certain parts of the slope to infiltrate into the permeable layer for discharge, further accelerating rainwater drainage.

[0025] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Please refer to Figures 1-5 This embodiment provides a flood control slope protection device for water conservancy projects, including a protective slope 2 set above a riverbank 1. The slope surface of the protective slope 2 is provided with a permeable layer 3. A slope protection foundation layer 4 formed by permeable concrete is fixed above the permeable layer 3. The slope protection foundation layer 4 forms a plurality of filling cavities 41. The filling cavities 41 are provided with plastic mesh 5 and planting soil 6 covering the plastic mesh 5. The plastic mesh 5 forms planting cavities 51 for planting slope protection vegetation. A permeable channel 7 is provided inside the riverbank 1. One end of the permeable channel 7 is connected to the lower part of the permeable layer 3, and the other end of the permeable channel 7 is connected to the river channel 12. By arranging plastic mesh within the filling cavity of the slope protection base layer, vegetation can be effectively fixed and soil can be retained, preventing soil erosion. By combining a permeable layer with permeable channels, infiltrated rainwater can be quickly discharged into the river channel, preventing rainwater from soaking the slope for extended periods and improving the protection effect. In addition, the slope protection base layer is formed by pouring permeable concrete, which allows some rainwater from certain parts of the slope to infiltrate into the permeable layer for discharge, thus accelerating rainwater drainage to some extent.

[0027] As an improved implementation method, refer to Figure 1 and Figure 2The protective slope 2 is provided with a protective stone layer 8 at its toe, distributed along the riverbank 1. A reinforced retaining wall 9 is provided on the side of the protective stone layer 8 closest to the river channel 12. The combination of the protective stone layer and the reinforced retaining wall can prevent the water flow in the river channel from directly impacting the riverbank and the protective slope.

[0028] In some implementations, reference Figures 1-4 The slope protection base layer 4 has protruding borders 42 distributed around the outer periphery of the filling cavity 41, and a water guiding channel 43 is formed between the corresponding borders 42 of two adjacent filling cavities 41. The water guiding channel is formed by the protruding borders, so that rainwater on the slope can be quickly drained downwards to avoid soil erosion.

[0029] In some specific implementation methods, refer to Figure 1 and Figure 2 The upper part of the protective stone layer 8 is provided with a drainage ditch 81 distributed along the direction of the river channel 12. One side of the drainage ditch 81 is connected to the water guide channel 43, and the other side of the drainage ditch 81 is connected to a drainage pipe 82 facing the river channel 12. In this way, rainwater diverted from the water guide channel can be discharged into the river channel using the drainage ditch and drainage pipe.

[0030] As an example, such as Figure 4 As shown, the filling cavity 41 is square in shape and is distributed in a matrix on the slope protection foundation layer 4. This facilitates casting and forming, and the drainage channels form a crisscrossing slope drainage system on the slope protection foundation layer, which can also quickly divert rainwater from the slope to the river channel during rainy days.

[0031] As an improved implementation method, refer to Figure 2 and Figure 3 The filling cavity 41 is fixed with a reinforced mac pad 10 covering the surface of the planting soil 6, thereby reinforcing and protecting the planted vegetation and preventing rainwater from directly washing away the soil, thus preventing the vegetation from dying due to soil erosion.

[0032] In some implementations, reference Figure 1 , Figure 2 and Figure 4 The slope protection foundation layer 4 is provided with anchoring holes 44, and anchoring rods 11 are installed in the anchoring holes 44 and inserted into the slope protection 2. By adding anchoring rods, the connection between the slope protection foundation layer and the slope protection can be improved, thereby enhancing the protection effect.

[0033] As a preferred embodiment, such as Figure 2 and Figure 4 As shown, the anchor rod 11 is perpendicular to the slope surface of the protective slope 2.

[0034] In some specific implementation methods, such as Figure 5As shown, the plastic mesh 5 is a geocell with a three-dimensional mesh structure formed by HDPE sheet material, which has a certain degree of elasticity and is convenient for installing and planting vegetation.

[0035] In some specific embodiments, the permeable channel 7 includes a permeable mesh pipe formed by a geonet and crushed stone filled within the permeable mesh pipe; the permeable layer 3 is made of sand and gravel. Specifically, such as... Figure 2 As shown, the permeable channel 7 comprises two sections, one vertically distributed and the other horizontally distributed. In this way, infiltrated rainwater can be quickly discharged through the numerous gaps between the gravel or sand.

[0036] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
