Common Causes of Geomembrane Seam Leakage and Corrective Actions
Engineering answer
Leakage is caused by the formation of a pre-differentiated welding layer of lead or lead after construction damage. The former is most often associated with water dust pollution, insufficient test lead, temperature/speed/pressure mismatch and multi-layer crossings; the latter is common in soil, vehicle, hard material or uneven deposition. Repair cannot be done only on suspected graphite sites, defective boundaries should be found, removed or covered repair and re-examination.

Acceptance points and common risks
- Blind HeatingRepeated roasting causes the film to thin, oxidize or form new stresses.
- Just fill in the blanks.When the same parameter is out of control, the neighboring pump should also expand the sampling.
- No running rainfallThe use of pressure relief may not guarantee drying and safety.

Steps to landing
- Collecting recordsThe first is the "Curveil" and the second is the "Curveil".
- Separation of sectionsThe scope of the project is reduced from the bridging point, cross-sectional point and correction point.
- Exposing defectsClean and dry and decide whether to remove it.
- Repair and repairThe same material is added to the same piece or weighted, recording the coordinates and results.

Key parameters and quick judgement tables
| The phenomenon | Possible causes | Disposal |
|---|---|---|
| Air pressure decreases rapidly | Double or terminal air leakage | Fixed after segment location |
| The empty box is bubbling. | Squeezing needle holes/edge defects | The process of grinding and polishing |
| The smoothness of the interface | Inadequate or contaminated | Expanded inspection of the staff |
| Water leaks after the soil is covered | The first is the "Straw or Tear" | Separate detection and excavation repairs |
