Embodiment Construction
[0010] figure 1 It is a schematic diagram of construction using geotechnical mold bags in embankments, wherein 1 is mold bags, 2 is fixed piles, 3 is backfilling rocks, 4 is backfilling rocks at the bottom, and 5 is concrete capping. After the mold bag is fixed, the concrete canned in the mold bag is filled with concrete avalanche, so as to complete the embankment slope protection project.
[0011] The composite geotechnical mold bag of the present invention is composited by double-layer woven geotechnical mold bag cloth and spun-bonded polyester needle-punched nonwoven fabric, and hot-melt viscose is used as a binder in the composite process. The nonwoven fabric produced by spunbond method is relatively mature. The nonwoven fabric produced has high strength, good stability, and high elongation rate. It is further consolidated through the needle punching process, and the product has better deformation ability, which is suitable for the production of composite geotextiles. Sin...

The invention provides a production method for composite geotextile model bag cloth. The production method comprises the steps of: selecting raw materials of weft and warn yarns and looping lines, weaving double-layer looping model bag cloth, producing base cloth, and compositing, wherein the double-layer looping model bag cloth is produced during the weaving step by adopting a shuttleless loom; during the base cloth production step, polyester raw material is selected and non-woven cloth is produced through a spunbonded method and a needling technology; and during the compositing step, an styrene-butadiene-styrene block copolymer (SBS) thermoplastic elastomer and a petroleum-asphalt mixture are coated on the surface of the non-woven cloth, and the double-layer looping model bag cloth and the coated non-woven fabric are thermally rolled to be composited. The composite geotextile model bag cloth provided via the invention has outstanding performance of stretching, and can be adapted to the complex shape of a bank ground, and can improve the engineering applicability of a model bag.
Description
technical field [0001] The invention relates to a method for producing a composite geomembrane bag, which belongs to the field of textile materials and building materials, in particular to a method for producing a geomembrane formed by compounding woven fabrics and nonwoven fabrics. Background technique [0002] The application of geosynthetics in engineering is a new technology developed in recent decades. It was introduced into my country in the late 1970s and began to be developed and used. Geotextile bags are continuous or individual double-layer bags made of synthetic fiber filaments. Mold bag concrete is to pour concrete or cement mortar into the mold bag through a high-pressure pump. The thickness of the concrete is controlled by the shape of the mold bag. After the concrete or cement mortar solidifies, it forms a plate-like structure or other structures with a certain strength, which can meet the requirements of the project. needs. As a new type of building materia...
