What are the main anti-seepage construction work of HDPE geomembrane

HDPE geomembrane is a kind of geotechnical material, and it has gradually been widely used. The geomembrane has good anti-seepage performance, but we must do the corresponding anti-seepage construction work before construction. For this information, everyone How much do you know, today I will give you a detailed introduction:

　　 1. Clean and level the tank before anti-seepage and anti-corrosion. There should be no sharp debris within 25mm of the vertical depth of the laying surface: such as rubble, stones, concrete particles, steel bar heads, metal or other debris that are sufficient to pierce the HDPE geomembrane.

　　2. The geomembrane is a flexible material, which can be used as a wrap lining in any shape according to any structure of the pool body. All corners and right-angled parts should be rounded or chamfered to avoid damage to the geomembrane.

　3. After laying, it should be welded immediately. Pipe nodes, internal and external corners, corners and other difficult-to-handle places can be welded with hot air blowers and extrusion welders.

　　4. If it is in the design stage, it can be anchored in embedded form. The HDPE cat's claw is pre-buried in the concrete wall, and when it is laid at the designated position, it is directly welded to the HDPE cat's claw to form a complete impermeable body. The brick wall can also be used to press the edge, the HDPE geomembrane is laid to the required position, the edge is returned to the wall, and the brick is fixed.

　　5. Edge-holding anchorage: Use expansion bolts and layering strips for edge-holding anchorage. After pressing the edges, seal and weld the anchored parts with HDPE film to form a complete anti-seepage and anti-corrosion lining.

    The main anti-seepage construction work of HDPE geomembrane is mainly these. We must carry out the correct operation according to the instructions, and only in this way can its performance be fully demonstrated.
