Problems solved by technology

[0002] At present, in the manufacture of anti-seepage materials at home and abroad, most of the traditional anti-seepage materials for engineering are PE film, PVC film or composite geomembrane products of geotechnical materials and PE, PVC films. Work on the construction site, and after the geomembrane is welded, a special sealing test must be done to meet the requirements of use. Not only that, once the traditional anti-seepage membrane is punctured or damaged by sharp objects during construction or use After that, the ideal anti-seepage effect cannot be achieved.

Embodiment 1

[0013] Example 1: Send the woven fabric and the non-woven fabric respectively at a speed of 2 m / min. Send them to the acupuncture machine through the cloth guide roller. The acupuncture speed is 2 m / min. The acupuncture frequency is 300 times / min , so that it is connected into a composite base fabric whose strength and elongation meet the design requirements. When the composite base fabric is sent into the powder spreading device at 2 m / min, the powder spreading roller starts to sprinkle powder at a speed of 400 g / min. Adjust the horizontal feeding spiral roller to feed the bentonite to the entire width of the composite base cloth. As the composite base cloth moves forward, the uniform roller will evenly mix the powdery or granular ore on the composite base cloth with the nutritional soil. Spread out, and send the non-woven fabric and the composite base cloth with bentonite to the roll at a speed of 2 m / min, and send it to the acupuncture machine through the cloth guide roller....

Embodiment 2

[0014] Example 2: Send the woven fabric and the non-woven fabric to the roll at a speed of 3 m / min respectively. Send it to the acupuncture machine through the cloth guide roller. The acupuncture speed is 3 m / min. The acupuncture frequency is 700 times / min , so that it is connected into a composite base fabric whose strength and elongation meet the design requirements. When the composite base fabric is sent into the powder spreading device at 3 m / min, the powder spreading roller starts to sprinkle powder at a speed of 800 g / min. Adjust the horizontal feeding spiral roller to feed the bentonite to the entire width of the composite base cloth. As the composite base cloth moves forward, the uniform roller will evenly mix the powdery or granular ore on the composite base cloth with nutrients. Spread out, and send the non-woven fabric and the composite base cloth with bentonite to the roll at a speed of 3 m / min, and send it to the acupuncture machine through the cloth guide roller. ...

Abstract

A method for preparing wide width of composite earth work material includes feeding woven or nonwoven cloth, knitting them to be composite backing cloth, feeding composite backing cloth, laying alta-mud on it uniformly, feeding nonwoven cloth and composite backing cloth with alta-mud on, knitting them for forming composite earth work material, winding and packing.

Description

Technical field: [0001] The invention relates to the technical field of civil engineering. Specifically, it relates to a method for manufacturing wide-width composite geotechnical materials. Background technique: [0002] At present, in the manufacture of anti-seepage materials at home and abroad, most of the traditional anti-seepage materials for engineering are PE film, PVC film or composite geomembrane products of geotechnical materials and PE, PVC films. Work on the construction site, and after the geomembrane is welded, a special sealing test must be done to meet the requirements of use. Not only that, once the traditional anti-seepage membrane is punctured or damaged by sharp objects during construction or use After that, the ideal anti-seepage effect cannot be achieved. Contents of the invention [0003] The purpose of the present invention is to provide a kind of manufacturing method of wide-width composite geotechnical material. A kind of novel anti-seepage mater...
