First, technology ① geomembrane laying laying and deployment direction, or to E from the E to W by the W, each piece laying length, including both sides of the retaining wall height once completed. ② laying order, since the channel axis to S, N side forward. ③ construction process, do first lake geomembrane protective layer of mortar (20-30mm), to do the vertical retaining wall paste. ④ geomembrane and retaining walls paste process. The adhesive is painted on the adhesive surface of the geomembrane and retaining walls, dried allowed to stand for about 5 minutes, then paste, squeeze, Dover. Adhesive mix asphalt emulsion paints, cement, water from. Paste is completed, the water level above the solder nail anchor, and waterproof, anti-corrosion treatment. Second, the quality inspection 1, materials and construction of geomembrane Quality and Technical Supervision issued the implementation of polyethylene geomembrane national standards. 2, construction quality inspection, into the construction unit self-test, contractors and other content sampling. 3, welding quality inspection, the "Inflation Pressure Law", repairing damage, "visual method" to detect indicators of inflation pressure 0.06Mpa. 4, quality inspection process includes a step handover procedure, final acceptance and so on. 5, artificial lake normal leakage: ≤15mm / 24h (including evaporation loss of the season). Third, the construction progress of the Japanese effect, one unit per day according to the construction area of ??2,000 to 2,500 square meters.
