Description

Technical Field

[0001] The utility model relates to the technical field of geotextiles, in particular to a reinforced geotextile. Background Art

[0002] In the reinforcement and reinforcement projects of dams, retaining walls and high and steep slopes, the slope protection and reinforcement usually adopts the reverse geogrid reinforced soil slope. The reinforcement is a multi-layer unidirectional geogrid, and the fill soil is used as the filling material. The tensile strength of the geogrid can form a locking, friction and bite effect on the soil, and it can play a very good effect on the bearing capacity of the foundation. The multi-layer mesh structure reinforces the bottom of the base bed, achieves good overall shear resistance, and enhances the stability of the foundation.

[0003] However, the existing geogrids have the disadvantage of mesh size. Sometimes it is necessary to lay geotextiles such as geotextiles to play the role of isolation, filtration and back-infiltration to reinforce the soil foundation and increase the life of the project. However, the existing geotextiles have the problem of low friction with the soil surface and poor stabilization effect on the foundation in this application condition. Utility Model Content

[0004] The utility model aims at the above problems existing in the prior art and provides a reinforced geotextile which can enhance friction and is beneficial to enhancing foundation stability.

[0005] The utility model solves the above-mentioned technical problems with the following technical solutions: a reinforced geotextile, characterized in that it comprises warp yarns, weft yarns and reinforcing yarns, wherein the warp yarns and weft yarns are interwoven with each other to form a fabric body, and the reinforcing yarns are in the structural form of reinforced warp yarns and / or reinforced weft yarns; a plurality of reinforcing yarns form a reinforcing yarn group, the reinforcing yarn group is interwoven with the fabric body to form reinforcing strips protruding from the fabric body, a plurality of reinforcing strips are arranged at intervals along a direction perpendicular to their length to form a reinforcing group, a plurality of reinforcing groups are evenly distributed along a direction perpendicular to the length of the reinforcing yarns, in each reinforcing group, the reinforcing yarn group is intermittently interwoven with the fabric body along its length to form floating lines, and the floating lines float on the surface of the fabric body to form reinforcing rings.

[0006] Furthermore, the floating lines formed by the same reinforcement group are arranged at intervals in the length direction of the reinforcement yarn.

[0007] Furthermore, the floating threads formed by the same reinforcement group float alternately on the front and back sides of the fabric body in the length direction of the reinforcement yarn.

[0008] Furthermore, when the reinforcing yarns are reinforcing warp yarns and reinforcing weft yarns, the floating yarns formed in the warp direction and the floating yarns formed in the weft direction are overlapped or alternately arranged in the fabric surface direction of the fabric body.

[0009] Furthermore, the warp yarn and weft yarn are made of polyester industrial filament, polypropylene monofilament, polypropylene split film yarn or polypropylene industrial filament, and the reinforcing yarn is made of twisted yarn of polyester industrial filament, polypropylene monofilament, polypropylene split film yarn or polypropylene industrial filament.

[0010] Furthermore, the strength of the reinforced ring is not less than 1KN.

[0011] The beneficial effect of the utility model is that the utility model forms reinforcing strips protruding from the fabric body by interweaving the reinforcing yarn group and the fabric body, forming an uneven fabric surface structure, and the formed reinforced ring structure, which can greatly increase the friction between the geotextile and the foundation, stabilize the foundation structure, reduce deformation under external load and slope interface slippage, and improve the service life of the reinforced retaining wall project.
