After the dam body is filled and the reservoir bottom is compacted to meet the design requirements, and the composite geomembrane impermeable body protective layer is prepared according to the design requirements, the construction technology of the composite geomembrane impermeable body is: the composite geomembrane is in place and the paving is straight → Butt joint, bottom fiber butt joint (stitching) → membrane material butt joint, hot melt pressure welding → inflation pressure (or negative pressure method) → surface fiber butt joint (sewing) → reserved capacity.

Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying the impermeable membrane, please make sure that there is no gap in the corner. If there are gaps, they should be filled in time during construction, and the laying order should be determined according to the specific conditions of the moisture content of the laying site. If there are pores, the air should be vented at the air bubble, and the anti-permeable membrane at the vent should be cleaned for subsidies.

The joints of geomembrane fabrics are inevitable during the construction process.

In order to achieve the dual purpose of obtaining materials on site and dredging the river, graded natural gravel is used as the filling material. However, under the high water level of the river, the embankment filled with gradual natural gravel will seep obviously, causing the embankment or quicksand pipeline to collapse. occur. In order to solve the above problems, composite geomembrane is placed on the front and bottom of the dam.

The anti-seepage geomembrane is the main component of the anti-seepage layer of the modern sanitary landfill.
