The Anti-seepage Membrane is Constructed Below Zero Degrees Celsius
The construction methods of impermeable membranes in different temperatures are also different, especially in cold weather, the construction of impermeable membranes is a big problem. Generally speaking, the weather temperature is above zero when the anti-seepage membrane is constructed. Construction can also be carried out below zero, but several aspects need to be noted:
1. When laying the impermeable membrane in cold weather, it should be handled with care and it is strictly forbidden to throw it at will to avoid damage to the impermeable HDPE geomembrane acceptance test method due to weather and external forces.
2. When welding, the temperature of the welding machine should be slightly higher than normal to facilitate the adhesion of the impermeable membrane. Welding machine should slow down and travel at a uniform speed when walking.
3. In cold weather, the frost-prone material on the HDPE impermeable membrane is easy to be wiped clean while welding and kept in a dry state without water stains.
4. The debris on the contact surface of the HDPE impermeable membrane such as the engineering ground and slope surface should be cleaned up. In cold weather, the impermeable laying process of anti-seepage geomembrane is more likely to be damaged by external forces.
When performing anti-seepage membrane construction, it is necessary to strictly follow the corresponding rules, so that the quality of construction can be truly guaranteed. For the anti-seepage membrane construction, the requirements for temperature and weather must be carried out in accordance with the above precautions. Ensure the construction quality and construction effect.
