Embodiment Construction

[0021] Such as figure 1 , figure 2 As shown, this embodiment is a green and environmentally friendly highly absorbent filter composite geotextile, including polypropylene geotextile 2, warp-knitted composite geotextile 1 and polyester staple fiber needle-punched geotextile 3, warp-knitted composite geotextile 1, There is a layer of adsorbent 4 on the bottom, and the polypropylene geotextile 2 and polyester staple fiber needle-punched geotextile 3 are respectively attached to the top and bottom of the woven composite geotextile through the adsorbent 4, and then squeezed and rolled through the warp and weft. The polypropylene geotextile 2, the warp-knitted composite geotextile 1 and the polyester staple fiber needle-punched geotextile 3 are sewed together to form an overall structure, and the distance between the warp and weft is no more than 1 cm.

[0022] The composite geotextile of this example has a width of 3m, a length of 15m, a thickness of about 4mm, and a weight of ab...

Abstract

The invention relates to environmental-friendly high-adsorbability inverse filtering compound geotextile and a use structure thereof. The invention aims to provide the environmental-friendly high-adsorbability inverse filtering compound geotextile and the use structure thereof; and the environmental-friendly high-adsorbability inverse filtering compound geotextile is simple in structure, convenient and fast to manufacture and simple in construction, can achieve environmental friendliness, no pollution, excellent adsorption of microorganisms, impurities and harmful substances, meanwhile, cannotinfluence normal water exchange, and achieves the construction quality control purpose. The environmental-friendly high-adsorbability inverse filtering compound geotextile is characterized by comprising polypropylene geotextile, warp-knitted compound geotextile and polyester staple fiber acupunctured geotextile; the upper and lower surfaces of the warp-knitted compound geotextile are each coatedwith a layer of adsorbent; and the polypropylene geotextile and the polyester staple fiber acupunctured geotextile are adhered to the upper and lower surfaces of the warp-knitted compound geotextile by the adsorbents. The environmental-friendly high-adsorbability inverse filtering compound geotextile is suitable for hydraulic and hydropower engineering and underwater engineering, such as river channels and ports.

Description

technical field [0001] The invention relates to a green environment-friendly high-adsorption reverse filter adsorption geotextile and its use structure. It is suitable for underwater projects such as water conservancy and hydropower projects, river courses, and ports. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving, and can be combined with geomembrane to become geotechnical anti-seepage material. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextiles have high strength. Due to the use of plastic fibers, they can maintain sufficient strength and elongation in dry and wet conditions. They can resist corrosion for a long time in soil and water with different pH levels. There are gaps between fibers and good water permeability. It is not damaged by microorganisms and moths, and is convenient for construction. The material is light...
