Description

Technical Field

[0001] The utility model relates to the technical field of ecological slope protection, in particular to an ecological slope protection for water conservancy projects. Background Technique

[0002] Water conservancy ecological slope protection is a slope protection technology that comprehensively uses 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. After the excavation of the side slope is formed, by planting plants, the interaction between plants and rock and soil bodies is used to protect and reinforce the surface layer of the side slope, so that it can not only meet the requirements for the stability of the surface layer of the side slope, but also restore the damaged natural ecological environment. It is an effective means of slope protection and slope fixation.

[0003] During the construction of existing water conservancy ecological slope protection, in order to ensure the greening degree of the slope, concrete grid frames are often directly laid on the slope ground, which can protect the soil on the slope surface, reduce soil erosion, and plants can be planted in the concrete grid frames;

[0004] The inner notch of the existing concrete grid frame has a smooth surface. After filling the inner notch of the concrete grid frame with soil and planting plants, although the plants can reinforce the soil, the connection force between the soil and the concrete grid frame is weak. In this way, during the long-term rain erosion process, the concrete grid frame is very easy to slide down on the slope protection surface, resulting in the exposure of the slope soil. In order to avoid this situation, based on this, an ecological slope protection for water conservancy projects is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide an ecological slope protection for water conservancy projects to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: an ecological slope protection for water conservancy projects, including a hexagonal soil grid frame. There are two groups of polygonal stepped grooves formed inside the hexagonal soil grid frame, which are symmetrically arranged with the central symmetry plane of the hexagonal soil grid frame in the vertical direction as the center. The polygonal stepped grooves are composed of multiple polygonal grooves with gradually increasing outer wall dimensions, and the polygonal groove with the smallest size is close to the vertical central symmetry plane of the hexagonal soil grid frame;

[0007] When filling the soil inside the hexagonal soil grid frame, the filled soil is in a "convex"-shaped stepped state through the polygonal stepped grooves, so as to realize the function of increasing the connection force between the filled soil and the hexagonal soil grid frame;

[0008] Filling slots communicating with the polygonal stepped grooves are opened at the upper and lower ends of the hexagonal soil grid frame, and the filling slots are used to enable the soil to completely fill the polygonal stepped grooves.

[0009] As a further solution of the utility model: six filling notches are respectively arranged at the upper and lower ends of the hexagonal soil grid, and the two filling notches are circumferentially distributed around the center of the hexagonal soil grid, and two groups of the filling notches distributed up and down are staggeredly distributed in the circumferential direction.

[0010] As a further solution of the utility model: the two groups of filling notches are communicated with the smallest-sized polygon groove located in the middle.

[0011] As a further solution of the utility model: reinforcing hole grooves and storage grooves are formed at six corner positions of the hexagonal soil grid, the storage grooves are symmetrically distributed at the upper and lower ends of the reinforcing hole grooves, and the inner diameter of the storage groove is larger than that of the reinforcing hole groove.

[0012] As a further solution of the utility model: the hexagonal soil grid, the polygon stepped groove, the filling notch, the reinforcing hole groove and the storage groove are integrally formed by a concrete casting mold.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] By arranging the polygon stepped groove and the filling notch, the filled soil can be in a "convex"-shaped stepped state, and the filled soil forms extrusion on the hexagonal soil grid. Compared with the traditional soil grid structure with a smooth surface, the installation firmness of the hexagonal soil grid is further improved. In addition, through the cooperation of the reinforcing cone nails and the reinforcing hole grooves, the connection force between the hexagonal soil grid and the slope can be further improved, and the tendency of the hexagonal soil grid to slide downward in the later stage can be reduced.

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0020] Please refer to Figures 1 to 3 Figures 1 to 3 , in the embodiment of the present utility model, an ecological slope protection for water conservancy projects includes a hexagonal soil grid 1. Inside the hexagonal soil grid 1, a polygonal stepped groove 2 is formed. There are two groups of polygonal stepped grooves 2 symmetrically arranged with the central symmetry plane in the vertical direction of the hexagonal soil grid 1 as the center. The polygonal stepped groove 2 is composed of multiple polygonal grooves with gradually increasing outer wall dimensions, and the polygonal groove with the smallest dimension is close to the vertical central symmetry plane of the hexagonal soil grid 1;

[0021] When filling the inside of the hexagonal soil grid 1 with soil, the filled soil is in a "convex"-shaped stepped state through the polygonal stepped groove 2, so as to achieve the function of increasing the connection force between the filled soil and the hexagonal soil grid 1;

[0022] Filling slots 3 communicating with the polygonal stepped groove 2 are opened at the upper and lower ends of the hexagonal soil grid 1. The filling slots 3 are used to enable the soil to completely fill the polygonal stepped groove 2;

[0023] Six filling slots 3 are respectively arranged at the upper and lower ends of the hexagonal soil grid 1, and two filling slots 3 are circumferentially distributed with the center of the hexagonal soil grid 1 as the center. The two groups of filling slots 3 distributed up and down are staggeredly distributed in the circumferential direction;

[0024] The two groups of filling slots 3 are communicated with the polygonal groove with the smallest dimension in the middle.

[0025] In this embodiment: when the hexagonal soil grid 1 is in use, during the process of filling the inside of the hexagonal soil grid 1 with soil, the soil can simultaneously fill the inside of the polygonal stepped groove 2. Finally, the filled soil is in a "convex"-shaped stepped state, and the soil has an extrusion force on the hexagonal soil grid 1. After planting plants later, the plant roots form a soil-fixing effect on the filled soil, and the filled soil fixes the hexagonal soil grid 1. Compared with the traditional soil grid structure with a smooth surface, the installation firmness of the hexagonal soil grid 1 is further improved, and the tendency of the hexagonal soil grid to slip downward in the later stage is reduced.

[0026] Please pay special attention to Figures 1 to 3 Figures 1 to 3 , at the six corner positions of the hexagonal soil grid 1, reinforcement hole grooves 4 and storage grooves 5 are formed. The storage grooves 5 are symmetrically distributed at the upper and lower ends of the reinforcement hole grooves 4, and the inner diameter of the storage grooves 5 is larger than the inner diameter of the reinforcement hole grooves 4.

[0027] In this embodiment: After multiple hexagonal soil frames 1 are spliced, the reinforcement holes 4 and storage grooves 5 on three adjacent hexagonal soil frames 1 form a circular hole. At this time, an external reinforcement cone nail can pass through the reinforcement hole 4 and be inserted into the slope soil layer. A circular convex block matching the aperture of the storage groove 5 is formed at the tail of the reinforcement cone nail. By snapping the circular convex block into the storage groove 5, the reinforcement of the three hexagonal soil frames 1 can be realized, thereby further improving the connection force between the hexagonal soil frame 1 and the slope.

[0028] Please refer specifically to Figures 1 to 3 , the hexagonal soil frame 1, the polygonal stepped groove 2, the filling notch 3, the reinforcement hole 4, and the storage groove 5 are integrally formed by a concrete casting mold.

[0029] In this embodiment: Producing the hexagonal soil frame 1 by the integral concrete casting process facilitates large-scale and standardized production;

[0030] It should be noted that: Through the filling notches 3 distributed in a vertically offset manner, not only is the pressing operation of the filled soil on the hexagonal soil frame 1 ensured, but also the hexagonal soil frame 1 can be placed in either the front or back direction, making the installation convenient and fast.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
