Abstract

The invention relates to a durable reinforced filter screen and a manufacturing method thereof. The durable reinforced filter screen comprises warp yarn and weft yarn which are interwoven, wherein the warp yarn comprises warp yarn repeat segments formed through alternate and repeated arrangement of multiple polyester fibers and multiple polypropylene fibers, and the weft yarn comprises weft yarn repeat segments formed through alternate and repeated arrangement of multiple polyester fibers and multiple polypropylene fibers. The manufacturing method is used for manufacturing the durable reinforced filter screen. The durable reinforced filter screen has the characteristics of both geogrid and woven geotextile, is excellent in mechanical property, good in structural stability and high in transverse sewing force and can achieve the effects of reinforcement, permeation and filtration and reflection crack prevention in construction of infrastructure such as roadbeds and foundations, so that the service life of the pavement is prolonged. The manufacturing method for the durable reinforced filter screen is simple and suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of geotechnical materials, in particular to a durable reinforced filter screen with the performances of geotextile and geogrid and a manufacturing method thereof. Background technique [0002] Geotechnical materials are synthetic materials used in geological engineering and civil engineering. Common geotechnical materials include geotextiles, geogrids, geotextiles, geotechnical mats, geonets, etc. Among them, geotextile is a permeable cloth-like geotechnical material produced by weaving technology. It has the advantages of light weight, good overall continuity, simple construction, and high strength. It is often used in foundations and roadbeds for reinforcement, isolation and protection. Filtration etc. Geogrid is a mesh-like grid-like product made of fiber as raw material. It has the advantages of high strength and creep resistance. It is suitable for various embankments and roadbed reinforcement, slope protection,...
