Geomembrane Uplift and Blistering: Causes and Remedial Measures
Engineering answer
The essence of the drum is that the pressure of the membrane is above the water or gas pressure of the membrane, which is pressurized and solidified, or that the substrate falls below the membrane causing the membrane to hang. The drum pack may temporarily disappear after the vacuum pool is empty, but the source of pressure is still present. The underground water level, gas, the position of the drum pack and the operating liquid level should be monitored first, and then the decision to add the exhaust gas, overweight, repair the substrate or re-consolidate the local solids should be made.

Acceptance points and common risks
- Directly breaking the airThe use of the drug can cause damage to the immune system and can release dangerous gases.
- Just a bag of sand.If the pressure source is not removed, the drum pack may be moved to the neighbouring area.
- The water is full and repairs are being made.High water pressure and wet surfaces are not safe for welding.

Steps to landing
- The border is recordedThe size, height and time of the drum kit are measured.
- Check the source of pressureMonitoring of groundwater, gas and liquid levels.
- Developing pressure reductionThe first step is to safely release the water gas and then perform the membrane operation.
- Restoration systemRepair of substrate, conduction and geomembrane and water storage in stages.
