Everyone is familiar with filament geotextile. Filament geotextile is a common geotechnical material. What should we pay attention to before laying to ensure the performance of filament geotextile to the maximum extent? Let’s introduce the preparations before the construction of filament geotextile:
What are the preparations for the construction of filament geotextiles
1. Roll manually; The cloth surface shall be flat and properly reserved with deformation allowance.
2. The filament geotextile is usually installed by lapping, stitching and welding. The width of stitching and welding is generally more than 0.1M, and the overlapping width is generally more than 0.2m. Geotextiles that may be exposed for a long time shall be welded or sewn. Hot air welding is the first connection method of filament geotextile, that is, the hot air gun is used to heat the connection of two pieces of cloth at high temperature instantaneously to make part of them reach the melting state, and a certain external force is immediately used to make them firmly bonded together. In the case that hot adhesive connection cannot be carried out in wet (rainy and snowy) weather, another method, i.e. suture connection method, shall be adopted for filament geotextile, i.e. double thread suture connection shall be carried out with special sewing machine, and chemical ultraviolet resistant suture shall be adopted.
