Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, specifically relating to a gabion mesh ecological slope protection structure. Background Technology
[0002] Gabion mesh is a type of metal mesh structure used in civil engineering for slope protection, flood control, and other applications. Ecological slope protection refers to using eco-friendly methods to reinforce slopes, prevent soil erosion, and promote the growth of natural vegetation.
[0003] In existing technologies, ecological slope protection primarily aims to prevent soil erosion, enhance slope stability, promote vegetation restoration, improve the ecological environment, and further consider landscape effects to achieve harmony with nature. Gabion mesh is woven from corrosion-resistant metals (such as galvanized steel wire, PVC-coated steel wire, or stainless steel) into mesh boxes, filled with stones or other natural materials. Compared to traditional concrete slope protection, which has poor ecological properties and obstructs water-land exchange, gabion mesh is permeable to water and air, promoting habitat for organisms; furthermore, it provides structural support, making it suitable for highly erosive environments.
[0004] However, some existing gabion meshes also have certain defects. The gabion mesh itself is not firmly fixed to the slope protection base, which cannot guarantee the slope protection strength. When the slope protection deforms, the gabion mesh is prone to collapse, which brings safety hazards. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a gabion ecological slope protection structure. This structure improves upon the shortcomings of gabion mesh by adopting a segmented design, which can effectively prevent the gabion mesh from collapsing when the slope deforms.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A gabion ecological slope protection structure includes multiple gabion boxes arranged sequentially along the slope, with a spacing strip between the bottom and top of adjacent gabion boxes. Each gabion box includes a frame, a wire mesh set inside the frame, and multiple first anchor bolt holes on each frame. The first anchor bolt passes through the frame and is inserted into the slope. The wire mesh is filled from bottom to top with a geotextile layer, a gravel layer, and a planting soil layer.
[0008] Furthermore, a second anchor rod is implanted within the spacer, and a concrete layer is poured within the spacer.
[0009] Furthermore, a drainage ditch is provided on the surface of the concrete layer.
[0010] Furthermore, the bottom of the frame is provided with a seepage hole that communicates with the drainage ditch.
[0011] Furthermore, the wire mesh is woven from galvanized steel wire with a diameter of 3mm.
[0012] Furthermore, multiple wire mesh binding connection holes are provided at the corners of the frame.
[0013] Compared with the prior art, the advantages of this utility model are as follows: First, this utility model adopts a segmented design, with multiple gabion boxes laid sequentially along the slope, and a spacer strip set between two adjacent gabion boxes. The spacer strip is anchored and filled with concrete. On the one hand, it can strengthen the fixing ability between gabion boxes and avoid the problem of gabion boxes collapsing sequentially when the slope deforms. On the other hand, it can set drainage ditches in the concrete layer to enhance the drainage capacity after planting greenery. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0019] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0020] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.
[0021] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0024] like Figure 1 As shown, a gabion ecological slope protection structure includes multiple gabion boxes 2 arranged sequentially along a slope 1, with a spacing strip between the bottom and top of adjacent gabion boxes 2. Each gabion box 2 includes a frame, a wire mesh set inside the frame, and multiple first anchor bolt 6 insertion holes on each frame. The first anchor bolt 6 passes through the frame and is inserted into the slope 1. The wire mesh is filled from bottom to top with a geotextile layer 3, a gravel layer 4, and a planting soil layer 5.
[0025] Compared to existing technologies, existing technologies frequently address soil erosion and landslides in reservoirs, riverbanks, mountains, and roadside slopes. To prevent these issues, slope protection and management are necessary. Commonly used materials include readily available stones or precast concrete structures, which can easily overlook the ecological function of the river channel. Therefore, a method using steel wire mesh cages manufactured with ecological gabion technology has been developed. This method utilizes gabion mesh for slope protection, ensuring slope stability while maintaining and restoring the ecological structure of the slope, preventing adverse effects from damage caused by stones and concrete. However, existing gabion mesh systems also have drawbacks; their resistance to deformation is poor after slope deformation, making them prone to sequential collapse. In order to overcome this problem, this utility model adopts a method of setting multiple gabion boxes 2 sequentially along the slope 1, and setting concrete partitions between adjacent gabion boxes 2. The concrete partitions are reinforced by embedding long anchor rods into the soil layer of the slope 1. After deformation occurs in some areas of the slope 1, the concrete partitions can prevent the gabion boxes 2 from collapsing sequentially.
[0026] A second anchor bolt 8 is embedded within the spacer strip, and a concrete layer 7 is poured within the spacer strip. The second anchor bolt 8 is a long anchor bolt, embedded within the slope coating 1. A drainage ditch 9 is provided on the surface of the concrete layer 7. A seepage hole communicating with the drainage ditch 9 is provided at the bottom of the frame. The spacer strip needs to be excavated in advance, and anchor bolts are inserted and concrete is poured according to the design.
[0027] The wire mesh is woven from galvanized steel wire with a diameter of 3mm. Galvanized steel wire has the advantage of lower price and provides general rust prevention, making it suitable for typical environments (such as neutral soil and freshwater areas). If slope 1 is located in a saline-alkali environment, corrosion-resistant steel wire such as PVC-coated steel wire or stainless steel wire should be used to prevent corrosion and strength reduction during long-term use. During weaving, the mesh size is selected based on the particle size of the main stones in the subsequent crushed stone layer 4, commonly using 60×80mm, 80×100mm, or 100×120mm. After weaving, the wire mesh is threaded through multiple binding holes at the corners of the frame and secured to the frame. The binding wire used should be of the same specification and material as the wire mesh wire.
[0028] Before installation, a geotextile layer 3 needs to be laid inside the frame to prevent soil erosion. Then, gabion cages 2 are installed sequentially along the slope 1 and filled with crushed stone. Hard, weather-resistant natural stone (such as granite or limestone) should be selected, avoiding the use of brittle or easily weathered sandstone. The stone particle size is generally 1.5-2 times the mesh size (e.g., for an 80mm mesh, the stone particle size should be 120-160mm). Next, a planting soil layer 5 is laid on the surface of the crushed stone layer 4, and grass seeds or shrub seedlings are planted within the planting soil layer 5.
[0029] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
