4.Precautions In The Construction Of Reservior Liner
4.1 Preparation and Surface Cleaning
Before initiating the construction, it is crucial to ensure that the surface of the geomembrane is free from sand, soil, and other debris. Utilizing a hairdryer can effectively blow away these contaminants, maintaining the cleanliness of the membrane surface. To facilitate the welder’s mobility and enhance construction quality, position a long wooden board under the area designated for construction. This provides a stable, flat base for the welder to walk on. Prior to commencing formal construction, conduct test welding to determine the optimal parameters, including construction temperature, walking speed (generally between 1.5 to 2.5 meters per second), and welding temperature (ranging from 220 to 300 degrees Celsius). The test weld involves splicing two seams with a 10mm width, leaving a 10mm cavity between them to assess weld integrity.
4.2 Construction Process
Following successful test welding, proceed with the main construction by laying a 10-centimeter layer of sand evenly over the geomembrane as a cushion, which aids in leveling and compacting. Subsequently, apply a 10-centimeter layer of concrete for added protection. Timely placement of the cushion layer is vital after the slope composite geomembrane installation to prevent wind damage and premature aging due to sun exposure. Concrete protective layers further reinforce the geomembrane, ensuring its longevity and effectiveness.
4.3 Quality Assurance and Material Selection
Geomembranes come in two primary forms: single-layer films and multi-layer composite films composed of different resins. While single-layer films offer high elongation, beneficial for waterproofing, they have lower tensile strength and are prone to puncture when encountering gravel. They also necessitate stringent requirements for both supporting and protective layers. Conversely, composite geomembranes integrate a geomembrane with a geotextile, tailored to specific needs, enhancing overall performance.
4.4 Performance Criteria and Laying Techniques
Geomembranes must exhibit properties such as acid resistance, aging resistance, and corrosion resistance, alongside excellent low-temperature flexibility. Preference should be given to wide geomembrane sheets to minimize joints and bonding efforts onsite. In cases where narrower widths are selected, they should be pre-spliced into wider rolls either at the factory or in an on-site work shed, then rolled into long lengths for transportation to the laying site, reducing on-site workload. The preparation of the laying surface is equally important; it must be cleared of tree roots, weeds, sharp grass, and stones to ensure a smooth, level gravel cushion without protrusions or depressions, followed by rolling and compaction for stability.
