Artificial lakes and river channels laying impermeable film and lap method:
1. The impermeable film is transported to the site mechanically or manually, and the impermeable film should be laid manually. Laying geotextile should choose no wind or breeze weather, laying should be smooth, moderate tightness, and ensure that geotextile and slope, base contact.
2. The anti-seepage film should be laid from bottom to bottom on the slope, or it can be adjusted from top to bottom. The impermeable film at the top and bottom should be fixed after ecological bags of soil or fixed by anchoring ditch, and the slope should be equipped with anti-slip nails or U-shaped nails when laying impermeable film, and should be fixed with the paving, and can also be weighed by ecological bags of soil.
3. When the impervious film is found to be damaged or damaged, it should be repaired or replaced in time. The connection of two adjacent geotextile is welded together by hot melt welding method. The double track hot melt welding machine is used to weld the two impervious films together at high temperature.
4. In addition, when laying in water, the factor of water flow direction should be taken into account, and the upstream impervious film at the water flow should be bonded on the downstream impervious film.
5. Laying personnel should try to avoid walking on the impermeable film that has been laid, and should wear flat shoes to enter and control the scope of activity when required by the project. Irrelevant personnel are strictly prohibited to wear high heels or high heels.
