Film welding method 1. The welding temperature, speed and pressure are determined after experiments and inspections. 2. The welding should be stopped when the ambient temperature is too high or too low. 3. The welding rod is the same as the membrane material. 4. Every piece of oilfield impermeable membrane is welded on the day of laying. 5. The edge of the upper impermeable membrane at the weld should be polished to an inclination angle of 45° to improve the welding quality of the weld.

The power station consists of a composite geomembrane face rockfill dam, a spillway, a spillway, a diversion tunnel and a water diversion and power generation system.

The construction of geomembrane connection includes connection, welding and vulcanization methods. The connection method used in specific engineering practice should be reasonably selected according to different anti-seepage requirements and the characteristics of the selected geomembrane.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

Before the composite geomembrane paving, prepare the construction organization and formulate, explain the paving method and technical measures, and apply it after the supervisor's permission.

The quality of the geomembrane itself is very important to the safety protection of the river embankment. When transporting geomembrane, it should not damage or pollute the environment, and long-term contact should be avoided.
