Application of anti-seepage membrane - anti-skid anti-seepage membrane in the construction of large-scale water channel projects

The anti-seepage application of anti-seepage membrane in the construction of large-scale water channel projects has good heat and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength. As the density increases, the mechanical and barrier properties will correspondingly improve, and the heat resistance and tensile strength will also be higher; Can withstand corrosion from acids, alkalis, organic solvents, etc.

Anti slip and anti-seepage membrane laying:

1. Before laying the anti-seepage membrane, the corresponding qualified acceptance certificate documents of the civil engineering project should be provided.

2. Before cutting the anti-seepage membrane, its relevant dimensions should be accurately measured, and then cut according to the actual size. Generally, it is not advisable to cut according to the size shown in the diagram. Each piece should be numbered and recorded in detail on a dedicated table.

3. When laying impermeable membranes, efforts should be made to minimize the number of welds and save raw materials as much as possible while ensuring quality. It is also easy to ensure quality.

4. The overlap width between membranes is generally not less than 10cm, and the weld seam is usually arranged parallel to the large slope, that is, along the slope direction.

5. Usually, in corners and deformed areas, the joint length should be minimized as much as possible. Unless otherwise specified, welding seams should be avoided as much as possible within a range of 1.5 meters from the top slope or stress concentration area on slopes with a slope greater than 1:6.

6. During the laying of the anti-seepage membrane, artificial wrinkles should be avoided. When the temperature is low, it should be tightened and laid flat as much as possible.

7. After the completion of the anti-seepage membrane installation, walking and moving tools on the membrane surface should be minimized as much as possible. Any objects that can cause harm to the anti-seepage membrane should not be placed or carried on the membrane to avoid accidental damage to the membrane.
