[0002] Grouting membrane bags for slope protection, usually referring to geotextile bags, are a new type of building material used in slope protection projects. The membrane bags are usually woven from high-strength long filament fibers such as nylon, polypropylene, polyester, and vinylon. Some projects also use simple membrane bags made of double-layer geotextile sewn together. These materials have the characteristics of corrosion resistance, wear resistance, non-toxicity and harmlessness, which can ensure the long-term use of membrane bags in slope protection projects. Generally, they are double-layer bag-shaped fabrics, with a certain length of nylon rope connecting the two layers of fabric at a certain distance to control the thickness of the grouting.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figures 1 to 5As shown, this utility model provides a grouting membrane bag for slope protection, including a geotextile bag 1. The geotextile bag 1 has a square grid 2, and a square frame 3 is set inside the square grid 2. A first arc-shaped positioning component 4 is set on the front and rear sides of the square frame 3, and a second arc-shaped positioning component 5 is set on the left and right sides of the square frame 3. Fixing ears 6 are fixed at the four corners of the inner side of the square frame 3, and positioning insertion rods 7 are set on the fixing ears 6. The square frame 3 is filled with soil blocks 8. When the geotextile bag 1 is laid, the positioning insertion rods 7 can be used to fix the position of the square frame 3, and then the first arc-shaped positioning component 4 and the second arc-shaped positioning component 5 can position the geotextile bag 1 to ensure the position of the geotextile bag 1, so as to facilitate the grouting of the geotextile bag 1.
[0032] Specifically, the geotextile formwork 1 is composed of interlaced transverse geotextile formwork 101 and longitudinal geotextile formwork 102, which interlaced to form square cells 2.
[0033] Furthermore, the transverse geotextile bag 101 is positioned by the corresponding first arc-shaped positioning element 4, and the longitudinal geotextile bag 102 is positioned by the corresponding second arc-shaped positioning element 5.
[0034] Furthermore, the square frame 3 is fixed with staggered horizontal reinforcing ribs 9 and vertical reinforcing ribs 10 to improve the stress strength of the square frame 3. In turn, it works with the first arc-shaped positioning piece 4 and the second arc-shaped positioning piece 5 to support and fix the solidified geotextile bag 1, which is beneficial to the fixation of the geotextile bag 1.
[0035] It is worth noting that the positioning insertion rod 7 is composed of a blocking block 701, a rod body 702, and a conical head 703. The top and bottom of the rod body 702 are respectively fixedly connected to the blocking block 701 and the conical head 703. The fixing ear 6 is provided with a through hole 601 corresponding to the rod body 702.
[0036] It is worth noting that a trapezoidal platform 301 is provided on the inner wall of the square frame 3, and a partition net 11 is provided on the trapezoidal platform 301. The partition net 11 is connected to the square frame 3 by bolts 12. The partition net 11 is used to reduce soil loss with rainwater and does not affect the passage of green plants.
[0037] It is worth mentioning that green plants are planted on the soil block 8, which increases the soil retention capacity and enhances the aesthetics of the slope protection.
[0038] It is worth emphasizing that both the transverse geotextile bag 101 and the longitudinal geotextile bag 102 are multi-layer co-extruded membrane bags. The multi-layer co-extruded membrane bag consists of a barrier layer, an adhesive layer, and a support layer. The barrier layer commonly uses materials such as PA (nylon), EVOH (ethylene-vinyl alcohol copolymer), and PVDC (polyvinylidene chloride), which can effectively block oxygen, water vapor, carbon dioxide, and odors, extending the shelf life of the contents. The adhesive layer generally uses ethylene-vinyl acetate copolymer (EVA), ethylene-acrylic acid copolymer (EAA), etc., which firmly bond the barrier layer and the support layer, ensuring good peel force between the layers. The support layer mostly uses LDPE (low-density polyethylene), LLDPE (linear low-density polyethylene), or a combination thereof. The inner layer serves as a heat-sealing layer and must have good heat-sealing performance; the outer layer can be printed and needs to have good mechanical strength, transparency, and printability.
[0039] Working principle and process: While laying the geotextile bag 1, the position of the square frame 3 is positioned so that the transverse geotextile bag 101 is between the corresponding first arc-shaped positioning piece 4, and the longitudinal geotextile bag 102 is between the corresponding second arc-shaped positioning piece 5. Then, the positioning insertion rod 7 is inserted into the ground through the through hole 601 on the fixing ear 6 to fix the position of the square frame 3. The square frame 3 then positions the geotextile bag 1. After laying, grouting can be carried out. After the geotextile bag 1 expands, the first arc-shaped positioning piece 4 and the second arc-shaped positioning piece 5 can better limit the geotextile bag 1. After the concrete inside the geotextile bag 1 has solidified, the soil block 8 is filled into the square frame 3, and grass seeds are planted on the soil block 8. Finally, the mesh 11 is laid on the soil block 8 and fixed with bolts 12 to reduce soil loss. After the grass seeds germinate, they can continue to grow through the mesh 11 to beautify the slope environment.
