How to construct non-woven fabrics in architectural practice

1, hand scroll; The surface of cloth should be smooth, with appropriate deformation allowance.

2. The installation of filament or short silk geotextile usually adopts several methods such as lapping, sewing and welding. The width of splicing and welding is generally above 0. 1m, and the lap width is generally above 0.2M Geotextiles that may be exposed for a long time should be welded or spliced.

3. During construction, the geotextiles on the geomembrane naturally overlap, and the geotextiles on the geomembrane are sewn or welded by hot air. Hot air welding is the first connection method of filament geotextile, that is, the connection of two pieces of cloth is heated at high temperature instantly with a hot air gun, so that some of them reach a molten state and are firmly bonded together immediately under a certain external force.

In wet (rain and snow) weather, geotextile should adopt another method-sewing connection, that is, double-thread sewing connection with special sewing machine and chemical anti-ultraviolet sewing thread.

Precautions:

1. The materials shall be marked with signs, indicating the trademark, product name, code, grade, specification, implementation standard, manufacturer's name, production date, gross weight and net weight, etc.

2, geosynthetics should have the test report of the testing unit recognized by the state or department. When the materials enter the site, samples should be taken.

3. The materials shall be sealed during transportation, ventilated and dry when stored at the site, and shall not be exposed to sunlight, and shall be kept away from fire sources.

4, physical and mechanical indicators should meet the standards.

5. Before laying, the sundries on the embankment slope should be removed, and the slope, flatness and compactness should be checked and accepted.

6, non-woven fabric laying surface should be smooth, tight, avoid overhead.

7, laying process, workers are not allowed to wear hard shoes, are not allowed to pile stones on the cloth, it is strictly prohibited to knock stones on the cloth and all construction work that may cause cloth loss.
