Anti seepage requirements of tailings pond, high quality characteristics of HDPE geomembrane: production of lotus pond special membrane

1. The construction is simple: as long as the pool is excavated and leveled, no concrete cushion is needed;

2. Rapid construction: there is no solidification period for structural concrete;

3. Resistance to foundation deformation: HDPE geomembrane has good fracture elongation and can resist foundation settlement or foundation deformation;

4. Good effect: This is the biggest characteristic of HDPE geomembrane;

5. Recover after: This is the biggest feature of HDPE geomembrane. After using, it can be restored as long as it is put away and backfilled.

Laying of HDPE geomembrane: anti seepage requirement of tailings pond

1. Before laying HDPE geomembrane, the corresponding acceptance certificate of civil engineering shall be provided.

2. Before cutting HDPE geomembrane, the relevant size should be measured accurately, and then cut according to the actual situation. Generally, it is not suitable to cut according to the size shown in the figure. It should be numbered one by one and recorded in the special form in detail.

3. When laying HDPE geomembrane, try to minimize the welding seam and try to save raw materials on the premise of ensuring the quality. At the same time, it is easy to guarantee the quality.

4. The lap width of joints between membranes is generally not less than 10cm, which usually makes the weld arrangement direction parallel to the maximum slope, that is, along the slope direction.

5. Generally in the corner and abnormal section, the joint length should be reduced as far as possible. Except for special requirements, no welding seam shall be set within 1.5m from the top slope or stress concentration area on the slope with a slope greater than 1:6.

When laying HDPE, the temperature should be low.

7. After the completion of HDPE geomembrane laying, it is necessary to reduce walking and moving tools on the membrane surface as far as possible. Any objects that can cause harm to the anti-seepage membrane should not be placed on the membrane or carried on the membrane to avoid accidental damage to the membrane.
