Everyone is familiar with filament geotextile. Filament geotextile is a common geotechnical material. What problems should we pay attention to before laying to ensure the performance of filament geotextile to the greatest extent? Now let’s introduce the preparations for the construction of filament geotextiles:
Preparation of filament geotextile before construction
1. Roll manually; The cloth surface shall be flat and properly reserved with deformation allowance.
2. The installation of filament geotextiles usually adopts several methods of lapping, stitching and welding. The width of stitching and welding is generally more than 0.1M, and the lap width is generally more than 0.2m. Geotextiles that may be exposed for a long time should be welded or stitched. Hot air welding is the first method of connecting filament geotextiles, that is, use a hot-air gun to heat the connection of two pieces of cloth at an instant, so that some of them reach the melting state, and immediately use a certain external force to make them firmly bonded together. In wet (rainy and snowy) weather, when thermal bonding cannot be carried out, another method, suture connection method, shall be adopted for filament geotextiles, that is, double-line suture connection shall be carried out with a special sewing machine, and chemical ultraviolet resistant suture shall be used.
