Geomembrane construction program(1) removal of the substrate (2) Geomembrane laying (3) joint construction, testing (4) is coupled with the peripheral anchoring (5) Acceptance (6) applying a protective layer
Geomembrane Techniques
1: Large geomembrane laying should adopt mechanical operation, small volume geomembrane can be laid artificial.
2: The direction of laying geomembrane should meet the design requirements, and the least amount of joint, parallel to the seam position on large tensile stress direction.
3, geomembrane laying should not be too tight, it should be left more than enough pieces (approximately 1.5%) for stitching and changes in temperature. It should vary with the press shop at the corner of the film 2-5 meters 20-40㎏ put a heavy sand bags at intervals to prevent the wind.
4, geomembrane connection with the surrounding buildings, the use of bolts and steel layering and other member anchored. Around the corner, we should pay attention to proper cutting geomembrane, to ensure proper connection with the surrounding buildings.
5, before the geomembrane welding, weld sample test done, adjust the welding equipment to the best based on test results.
6, geomembrane welding, should always observe the welding quality. According to actual construction, welding equipment at any time to adjust to the optimum working condition.
7 junction formed between the geomembrane should be T-shaped, cross-shaped can not be made. T-shaped junction base material should be used up scar, scar size up to 300 mm × 300 mm can be. Scar right angle should be rounded.
8, geomembrane when there Weld, when the weld, the weld must be cut using a hot-melt extrusion welder to cut parts of the welding.
Geotextile construction methods
1, cleaning, leveling the construction site;
2, geotextile flat paving at the construction site;
1, the geotextile connection, flat ground construction lap width greater than 30 cm when lap, uneven ground or very bad foundation soil lap width greater than 50 cm;
2, acupuncture geotextile paving filling and leveling;
3, will fill compaction, and construction should pay attention to avoid rolling the vehicle directly on the acupuncture geotextile.Geomembrane construction program
