Description

High-permeability geotextile

Technical Field

The utility model belongs to the technical field of the textile technology is used in the industry and specifically relates to a high infiltration geotechnological cloth.

Background

The sponge city is a new generation of city rain and flood management concept, and means that the city has good 'elasticity' in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, absorbs, stores, seeps, filters and purifies water during raining, and releases and utilizes the stored water when needed. Because of the traditional city construction mode, the road is a hardened pavement everywhere, the city becomes very hard and does not breathe, and urban waterlogging is easily caused in rainstorm weather. Permeable pavement has become an important component of road drainage design as an important method of "ecological drainage". In the process, geotextile is required to be used for reinforcement, and high requirements are put on the strength and the water permeability of the geotextile. The traditional geotextile has small aperture and weak water seepage capability.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described in detail with reference to fig. 1. The high-permeability geotextile comprises a weft yarn 3, and a ground warp 1 and a skein 2 which are interwoven with the weft yarn 3. In this embodiment, the weft yarns 3, the ground warp 1 and the skein warp 2 are all made of polypropylene.

The ground warp 3 consists of a plurality of ground warp groups a, and a space is reserved between every two adjacent ground warp groups a; the skein warp 2 is positioned at two sides of the two outermost ground warps 1 of the ground warp group a and skeins with the ground warp 1 and the weft 3; the spacing is not smaller than the width of the ground warp 1. Two ends of two ground warps 1 at the outermost side of each ground warp group a are respectively provided with a skein warp 2, and a weaving process of a skein heddle is adopted during weaving, so that the two skein warps 2 are alternately positioned at two sides of the ground warp 1 to realize the skein with the ground warp 1 and the weft 2. The shape retention of the geotextile can be improved, and the phenomenon that the ground warp groups a slide on the ground warps 1 on the two sides to influence the strength and the water seepage performance of the geotextile is avoided.

The spacing between the two ground warp groups a is achieved during weaving by means of an empty reed, typically in the form of an empty 3-5 reed, so that the spacing is at least 3-5 times the width of the ground warp 1. The aperture in the space can be improved, and the water seepage performance is improved. The weaving work using the conventional geotextile at the ground warp 1 can ensure the weaving efficiency and the strength of the geotextile.

The cross section of the ground warp 1 is rectangular, the width of the ground warp is 78-95 filaments, and the thickness of the ground warp is 20-25 filaments; the cross section of the weft yarn 3 is oval, the length of the major axis is 35 filaments, and the length of the minor axis is 20-25 filaments; the cross section of the skein 2 is circular, and the diameter is 25-30 filaments. The weft yarns 3 are in an oval shape, so that the number of the yarns in the tearing triangular area can be increased during the tearing strength test, and the tearing strength is increased.

The density of the weft threads is 14-19 threads per inch, and the density of the ground warp 1 in the ground warp group a is 28-31 threads per inch; in this embodiment, the density of the weft is selected to be 15 threads per inch and the density of the ground thread is selected to be 29 threads per inch. The warp and weft density is set, firstly, the weaving difficulty is considered, so that the weaving process is smoothly carried out and the weaving effect is achieved. The size of the aperture formed by the warp yarn part a and the weft yarn 3 is considered, so as to meet the requirement of water permeability.

Example two

This embodiment will be described in detail with reference to fig. 1 and 2. The present embodiment relates to a high-permeability geotextile, which is different from the embodiments in that the weft yarn 3 in the present embodiment comprises a core portion 31 and a sheath portion 32; the section of the core 31 is circular, and the diameter of the core is 10-15 wires, 10 wires in the embodiment. The sheath portion 32 is polypropylene, and the core portion is one of polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate. In this example, polyethylene terephthalate was selected.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
