[0002] Geomembrane bag slope protection technology is widely used in ecological slope protection in water conservancy projects, road projects, slope protection and other fields. By using geomembrane bags to reinforce slopes, prevent soil erosion, and promote vegetation growth, the dual goals of engineering protection and ecological restoration are achieved.

[0003] However, the existing geomembrane bag slope protection structure is not stable enough and is prone to displacement. In addition, some geomembrane bags have a single internal filling material and lack ecological functions. They have poor adaptability, and traditional film bags are difficult to fit tightly to the slope surface. They are prone to gaps, which reduces the slope protection effect. There is still room for improvement in stability and ecology.

The thickness of the geogrid chamber 3 is smaller than the thickness of the geomembrane bag 2 . The geogrid chamber 3 is arranged in contact with the filling material 4 .

[0022] The present invention discloses a slope protection structure and construction method using octagonal combined geomembrane bags. The edge of the geomembrane bag 2 is designed to be a regular octagon. This design helps the geomembrane bags 2 to fit tightly and be arranged stably, helps to form a continuous slope protection layer, and improves the overall stability of the slope protection structure. The slope protection structure design formed by combining the regular octagonal geomembrane bags 2 is more evenly stressed, can better adapt to the irregular shape of the slope, reduce the stress concentration problem caused by shape mismatch, improve the protection effect of the slope body 1, and improve the safety of the slope body 1. A reserved space is formed between a plurality of geomembrane bags 2 arranged in a ring. The through hole 9 is used to install the connection assembly 5, which can lock and fix the geomembrane bag 2 on the slope 1 without damaging the geomembrane bag 2, which helps to enhance the overall stability and durability of the slope protection structure; the geogrid chamber 3 is embedded and installed on the side of the geomembrane bag 2 away from the slope 1, and is arranged in abutment with the filling material 4, which can be used to provide additional support and reinforcement, and also helps drainage and ventilation, facilitates the planting of plants, and plays a role in ecological restoration; the filling material 4 is selected as ecological concrete, which is not only used to provide necessary support and reinforcement, but also more conducive to plant growth and soil formation, and has a better ecological restoration effect. The present invention has a simple structure, is easy to construct, can effectively protect the slope, has high overall stability and durability, promotes plant growth and soil formation, realizes ecological restoration, overcomes the shortcomings of traditional slope protection methods, and is suitable for slope protection in various complex engineering environments and geological conditions.

[0023] In one embodiment of the present application, the slope body 1 includes a slope 102, the top of the slope 102 is a horizontally arranged slope top 101, and the bottom of the slope 102 is a horizontally arranged slope bottom 103. The regular octagonal geomembrane bag 2 is sequentially fitted on the slope top 101, the slope 102 and the slope bottom 103 to achieve protection of the slope body 1.

[0024] In one embodiment of the present application, the filling material 4 is made of ecological concrete, which contains nutrients required for plant growth, promotes plant growth, and also helps in soil formation and ecosystem recovery, thereby achieving an organic combination of slope protection and ecological restoration, and overcoming the poor ecological defects of traditional slope protection methods.

[0025] In one embodiment of the present application, the material of the geogrid chamber 3 is an eco-friendly material, strictly following the green manufacturing concept, and combined with the filling material 4 of ecological concrete, it not only reduces carbon emissions during the construction process, but also can achieve carbon sequestration by using planted plants.

[0026] In one embodiment of the present application, the geomembrane bag 2 is provided with perforations adapted to the geogrid chamber 3 , and the outer wall of the geogrid chamber 3 is prefabricated and fixedly connected to the side wall of the perforations.

[0027] In one embodiment of the present application, after the geomembrane bag 2 and the geogrid chamber 3 are firmly combined together in the factory through hot-melt technology, during the specific operation, the connection parts of the geomembrane bag 2 and the geogrid chamber 3 are pre-treated, the impurities and dust on the surface are cleaned, and then professional hot-melt equipment is used to heat the connection parts to a molten state. In the molten state, the two are tightly fitted, and after cooling, the two are firmly connected together. This hot-melt connection method has high connection strength, which can ensure that the geomembrane bag 2 and the geogrid chamber 3 will not loosen or fall off during long-term use, thereby ensuring the stability and reliability of the slope protection structure.

[0028] In one embodiment of the present application, the connection between two adjacent geomembrane bags 2 is also connected by hot-melt connection. When connecting, the sides of the two geomembrane bags 2 are aligned, and then the connection parts are heated and melted using hot-melt equipment. After cooling, the two geomembrane bags 2 are firmly connected together. This connection method not only has high connection strength, but also has good integrity after connection, which can effectively prevent rainwater or surface runoff from infiltrating from the connection, further improving the anti-seepage performance and stability of the slope protection structure.

[0029] In one embodiment of the present application, the geogrid chamber 3 is a square structure.

[0030] In one embodiment of the present application, the geogrid chamber 3 has a height of 0.15-0.2 m.

[0031] Further optimization scheme, the geomembrane bag 2 includes an inner layer 202 and an outer layer 201 which are arranged in a close relationship, the outer layer 201 is in close relationship with the slope 1, the geogrid chamber 3 penetrates the outer layer 201 on the side away from the slope 1 and is in close relationship with the inner layer 202; the outer layer 201 is attached to the outer wall of the geogrid chamber 3, and the inner layer 202 is attached to the part of the geogrid chamber 3 extending into the outer layer 201. Figure 6 As shown, the geomembrane bag 2 of the present invention is composed of an inner layer 202 and an outer layer 201 that are fitted together, which improves the sealing and durability of the geomembrane bag 2; the geogrid chamber 3 penetrates the outer layer 201 and is fitted and fixed to the inner layer 202, which enhances the connection strength between the geogrid chamber 3 and the geomembrane bag 2 and makes the structure more stable.

[0032] In one embodiment of the present application, the outer layer 201 is made of anti-seepage materials such as polyester fiber, and the surface of the outer layer 201 is a rough surface, which can enhance the friction between the geomembrane bag 2 and the surrounding soil, improve the stability of the structure, and reduce the risk of displacement caused by rain erosion or foundation settlement; the inner layer 202 is made of breathable and tensile-resistant materials such as non-woven geotextiles, which can adapt to different internal and external environmental conditions; the geomembrane bag 2 adopts a double-layer structure, with the outer layer 201 being anti-seepage and the inner layer 202 being breathable, which not only ensures good anti-seepage performance, but also provides a suitable breathable environment for plant growth.

[0033] Further optimization scheme, the geogrid chamber 3 is divided into several planting chambers, which are filled with planting soil 6 and planted with green plants 7. The geogrid chamber 3 is divided into several square planting chambers, which are filled with planting soil 6, reducing the risk of instability under rainfall conditions, and can achieve the fixation of a relatively thick foreign soil for planting green plants 7, thereby improving the survival rate of green plants 7, which not only enhances the ecological function of the slope protection structure, but also helps to beautify the environment and improve the overall effect of the slope protection structure; at the same time, the filling material 4 is ecological concrete, which contains nutrients required for plant growth. When the green plants 7 grow up, their roots enter the filling material 4, which can promote the growth of plants and the formation of soil, and facilitate the growth of green plants 7.

[0034] In one embodiment of the present application, the green plants 7 include but are not limited to shrubs, trees and other plants.

[0035] In a further optimized solution, a grouting port 8 is provided on one side wall of the geomembrane bag 2 for injecting the filling material 4 into the geomembrane bag 2. The grouting port 8 is provided on the side wall of the geomembrane bag 2, which facilitates the injection of the filling material 4 and improves the construction efficiency.

[0036] In one embodiment of the present application, the position and number of the grouting ports 8 can be adjusted according to actual needs to meet the construction requirements of different slopes 1.

[0037] In a further optimized solution, the connection components 5 are arranged in the reserved through holes 9 symmetrically arranged on the sides of the geomembrane bag 2. The connection components 5 are arranged in the reserved through holes 9, and each connection component 5 acts on the four geomembrane bags 2 around the reserved through holes 9, locking the geomembrane bags 2 to the slope 1.

[0038] Further optimization scheme, any side of any geomembrane bag 2 is arranged with no less than two groups of connection components 5. Figure 1 and attached Figure 3 As shown, each geomembrane bag 2 is fixed by at least two sets of connecting components 5, and they are all arranged symmetrically, which is convenient for fixing the geomembrane bag 2; at the same time, the connecting components 5 are arranged obliquely on the slope 1, effectively avoiding the generation of stress concentration.

[0039] In one embodiment of the present application, in order to improve the flexibility of construction and adapt to different terrain conditions, a connecting component 5 is not set at each reserved through hole 9; during actual construction, the connecting components 5 can be staggered or separated according to the on-site conditions to achieve better fixing effect and structural stability. Figure 3 The distribution is only the optimal choice of this embodiment, and an adaptive choice can be made according to actual conditions during specific implementation.

[0040] A further optimized solution is that the connection component 5 includes a threaded anchor rod 501 arranged corresponding to the center position of the reserved through hole 9, and the bottom end of the threaded anchor rod 501 is vertically anchored in the slope 1; an anchor gasket 502 is sleeved on the threaded anchor rod 501, and a nut 503 is threadedly connected to the threaded anchor rod 501, and the nut 503 abuts against the anchor gasket 502, and the anchor gasket 502 fixes the geomembrane bag 2 on the slope 1. The connecting assembly 5 is composed of a threaded anchor rod 501, an anchor gasket 502 and a nut 503; one end of the threaded anchor rod 501 is anchored in a drilled hole opened on the slope 1, and the anchor gasket 502 is sleeved on the threaded anchor rod 501. The side of the anchor gasket 502 away from the geomembrane bag 2 is abutted with a nut 503 that cooperates with the threaded anchor rod 501. The shape of the anchor gasket 502 is circular, and the diameter of the anchor gasket 502 is larger than the diameter of the through hole. The nut 503 cooperates with the threaded anchor rod 501 to press the geomembrane bag 2, thereby fixing the geomembrane bag 2.

[0041] In one embodiment of the present application, the threaded anchor rod 501 is vertically anchored at the top 101 and the bottom 103 of the slope, and is obliquely anchored on the slope 102, and the threaded anchor rod 501 is perpendicular to the top 101, the bottom 103 and the slope 102 respectively.

[0042] In one embodiment of the present application, the shape of the anchor pad 502 is not limited to a circle, and can also be made into a polygon, and the corners can be rounded to avoid scratching the geomembrane bag 2.

[0043] Further optimizing the scheme, a plurality of reserved through holes 9 are embedded with hollow chambers 10, and the hollow chambers 10 are filled with planting soil 6 for planting green plants 7. When the reserved through holes 9 are formed without installing the connection components 5, hollow chambers 10 can be embedded in the reserved through holes 9. After the construction is completed, the hollow chambers 10 are filled with planting soil 6, and then green plants 7 are planted to decorate the slope protection structure.

[0044] The present invention also discloses a construction method of a slope protection structure using an octagonal combined geomembrane bag, comprising the following steps: Clean the slope 1 and locate the installation position of the connection assembly 5 on the slope 1; first clean the surface of the slope 1 to ensure that the slope is flat and free of loose soil and rocks; then install the threaded anchor rod 501 in the drilled hole to ensure that the threaded anchor rod 501 is firmly fixed; Make a geomembrane bag 2, and then prefabricate the geogrid chamber 3 on the geomembrane bag 2; make a double-layer geomembrane bag 2 according to the designed size in the factory, and then pre-embed the geogrid chamber 3 on the top surface of the geomembrane bag 2, and then transport it to the construction site; The geomembrane bags 2 are laid along the slope 1, and the adjacent geomembrane bags 2 are tightly fitted without any gaps, so that the reserved through holes 9 between the adjacent geomembrane bags 2 are aligned with the position of the positioned connection assembly 5; starting from the top of the slope 101, the geomembrane bags 2 are laid downward along the slope surface, and the reserved through holes 9 formed between the geomembrane bags 2 are aligned with the threaded anchor rods 501. The adjacent geomembrane bags 2 should be tightly fitted and fixed by hot melting to avoid gaps; Assemble the connection components 5 to fix the geomembrane bag 2 on the slope 1; install the remaining connection components 5 except the threaded anchor rod 501 to fix the geomembrane bag 2 on the slope 1; Inject the filling material 4 into the geomembrane bag 2 and seal it for curing; inject the filling material 4 into the geomembrane bag 2 through the grouting port 8 and seal it, and then cure the filling material 4 to ensure that the filling material 4 can reach the set strength; Modify the space of the geogrid chamber 3 to complete the support of the slope 1; fill the geogrid chamber 3 with planting soil 6 and plant green plants 7; at the same time, embed the hollow chamber 10 in the reserved through hole 9 where the connecting component 5 is not set, and then fill the hollow chamber 10 with planting soil 6, and then plant green plants 7.
