Before laying HDPE geomembrane, shall, in conjunction with the civil engineering, building, design, owner of laying base to conduct a comprehensive inspection, comply with the design requirements, construction conditions, and delivery inspection records rear can construction. 2. The base quality should comply with the design requirements: foundation pit bottom slope, slope and slope ratio, the anchorage slot, slope and handling at the junction of righteousness, the warehouse wall concrete base shall be strictly meet the design requirements. 3. The base should be dry, compaction, smooth, no cracks, no obvious tips, no dirt, no sag, vertical depth should be 25 mm internal roots, rubble, stone, steel, glass crumbs. The flatness should be gradual change in the allowable range, the slope uniformity and the slope uniformity. The Angle of the Yin and the Angle of the base of the plane is a smooth transition, and the root of the column should be a circular arc. The basal surface is dry and the moisture content should be below 15%. 6. Basal uniform should be solid, dry density of soil basal shall not be less than 1.4 t / ㎡. After the approval of the inspection and approval of the construction, supervision, design unit, owner, and the general contractor, the construction of the working film shall be carried out. Chapter ii. The climate requirements for construction The temperature should be above five degrees centigrade, the geomembrane should be tense at low temperature, and the earthen membrane should be relaxed at high temperature. The wind is below level four. When the temperature is too low, the wind and snow weather should not be working. In wind weather, when the wind is affecting the construction of the earthwork, the HDPE film which is soldering is pressed in the sandbag.
