Description

Technical Field

[0001] This utility model relates to the field of geotextile soft sheet technology, and in particular to a tear-resistant geotextile soft sheet structure. Background Technology

[0002] Geotextile soft riprap is a flexible protective structure made of synthetic materials. It is mainly used in water conservancy projects for bottom protection, bank protection and waterway regulation. It is mainly used to cover the surface of the riverbed or bank slope to disperse the impact of water flow, prevent the underlying soil from being eroded and maintain the stability of the river.

[0003] Currently, existing geotextile riprap structures are prone to dynamic impact loads when the water flow velocity is consistently greater than 3 m / s. This can lead to stress concentration and tearing of the woven fabric layers, with cracks rapidly expanding and affecting the service life of the geotextile riprap. Therefore, in order to improve the tear resistance of geotextile riprap and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from existing geotextile riprap structures and application methods. Utility Model Content

[0004] The purpose of this invention is to solve the problem of stress concentration and tearing of the woven fabric layer in existing geotextile structures, and the rapid expansion of cracks, which affects the service life of the geotextile. Therefore, a tear-resistant geotextile structure is proposed.

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

[0006] A tear-resistant geotextile structure includes a bottom layer fabric, a filter cloth fixedly connected to the top of the bottom layer fabric, a plurality of first reinforcing ropes fixedly connected to the top of the filter cloth, a plurality of connecting rings snapped onto the first reinforcing ropes, a second reinforcing rope threaded between the plurality of connecting rings between two first reinforcing ropes, the second reinforcing rope being wavy, two first side sealing strips fixedly connected to the top of the filter cloth, the two first side sealing strips respectively pressing against the ends of the first and second reinforcing ropes, and a plurality of reinforcing tapes fixedly connected to the top of the filter cloth, the reinforcing tapes pressing against the first and second reinforcing ropes.

[0007] Furthermore, the first reinforcing rope is an ultra-high molecular weight polyethylene rope.

[0008] Furthermore, the second reinforcing rope is a nylon rope.

[0009] Furthermore, the reinforcing strip is a nylon braided strip.

[0010] Furthermore, the top of the filter cloth is fixedly connected with multiple connecting straps, which are sewn into a ring structure.

[0011] Furthermore, sand rib bags are fixedly connected between the plurality of connecting straps.

[0012] Furthermore, two second side sealing strips are fixedly connected to the top of the filter cloth, and the second side sealing strips are pressed against one end of the connecting strip and one end of the first reinforcing rope and the second reinforcing rope.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. A mesh layer is formed on the filter cloth by weaving the first reinforcing rope, the second reinforcing rope and the connecting ring, so as to prevent the bottom cloth and the filter cloth from being stressed and torn by water flow, so as to avoid affecting the service life of the geotextile soft drainage structure.

[0015] 2. The second reinforcing rope is made of nylon rope to improve wear resistance and impact resistance. Then, the first reinforcing rope is made of ultra-high molecular weight polyethylene rope to further improve tear resistance and corrosion resistance, thereby improving the performance of the geotextile soft embankment structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A tear-resistant geotextile soft shed structure includes a bottom layer fabric 1, which is made of 230g / m² polypropylene woven fabric to provide tensile strength and erosion resistance. A filter cloth 2 is sewn to the top of the bottom layer fabric 1. The filter cloth 2 is made of composite 150g / m² polyester staple fiber needle-punched nonwoven fabric to play a filtering role and prevent the loss of bottom soil particles.

[0022] The top of the filter cloth 2 is sewn with multiple first reinforcing ropes 3, and multiple connecting rings 5 ​​are snapped onto the first reinforcing ropes 3. The connecting rings 5 ​​are stainless steel elliptical rings. The same second reinforcing rope 4 is threaded between the multiple connecting rings 5 ​​between two first reinforcing ropes 3. The second reinforcing rope 4 is wavy. The wavy second reinforcing rope 4 further improves the tensile and torsional resistance of the structure.

[0023] The top of the filter cloth 2 is sewn with two first side sealing strips 6, which are respectively pressed against the two ends of the first reinforcing rope 3 and the second reinforcing rope 4. The top of the filter cloth 2 is sewn with multiple reinforcing strips 7, which are pressed against the first reinforcing rope 3 and the second reinforcing rope 4.

[0024] The first reinforcing rope 3 is made of ultra-high molecular weight polyethylene, which enhances the tensile strength and tear resistance of the structure. The diameter of the first reinforcing rope 3 is greater than 8mm, and the breaking strength is ≥200kN / m. The second reinforcing rope 4 is made of nylon, and the diameter of the second reinforcing rope 4 is greater than 6mm.

[0025] The reinforcing band 7 is a nylon braided band. The use of nylon braided band 7 improves the tight connection between the first reinforcing rope 3 and the second reinforcing rope 4, ensuring the stability and durability of the structure.

[0026] Multiple connecting straps 9 are sewn to the top of the filter cloth 2. The connecting straps 9 are sewn into a ring structure. Sand rib bags 10 are sewn between the multiple connecting straps 9. Sand is filled into the sand rib bags 10 to form a grid-like counterweight. The combined design of the connecting straps 9 and the sand rib bags 10 effectively enhances the structure's resistance to deformation and erosion.

[0027] The top of the filter cloth 2 is sewn with two second side sealing strips 8. The second side sealing strips 8 press against one end of the connecting strip 9 and one end of the first reinforcing rope 3 and the second reinforcing rope 4. The first side sealing strips 6 and the second side sealing strips 8 ensure the compactness and integrity of the overall structure by pressing the connecting strip 9 and the two ends of the first reinforcing rope 3 and the second reinforcing rope 4.

[0028] The working principle of this embodiment is as follows: In use, the bottom layer cloth 1 provides basic support and protection, while the filter cloth 2 is responsible for filtering and preventing soil particles from being lost. Then, a mesh layer is woven on the filter cloth 2 by the first reinforcing rope 3, the second reinforcing rope 4, and the connecting ring 5, thereby preventing stress tearing of the bottom layer cloth 1 and the filter cloth 2 under the scouring of water flow. Then, the second reinforcing rope 4 is made of nylon rope to improve wear resistance and impact resistance, and has excellent corrosion resistance. Next, the first reinforcing rope 3 is made of ultra-high molecular weight polyethylene rope to further improve tear resistance and corrosion resistance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
