Construction method of 1.5mmHg HDPE geomembrane with smooth surface

Description :

　　The general characteristics of 1.5mmHg HDPE geomembrane (anti-seepage membrane) include physical properties, mechanical properties, chemical properties, thermal properties, and durability properties. Geomembranes place greater emphasis on their waterproof (anti-seepage) performance, deformation resistance, and durability in engineering applications. Numerous engineering practices have proven that geomembranes have excellent impermeability; Has good elastic strain capacity and can withstand different construction conditions and working stresses; It has good aging resistance, and the durability of geomembranes underwater and in soil is particularly outstanding. Our company produces geomembrane materials including high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC), and flexible ethylene vinyl acetate copolymer (EVA) geomembranes.

　　Our company produces 1.5mm HDPE geomembrane (anti-seepage film) with a thickness of 1 millimeter, a product width of 1 meter to 8 meters, and a length of 50 meters or 100 meters per roll. Product colors: black, white, blue, green, etc. Construction method of 1.5mmHg HDPE geomembrane with smooth surface

　　1、 The performance characteristics of 1.5mmHg HDPE geomembrane (anti-seepage membrane) are as follows:

　　1. It is a flexible waterproof material with a high anti-seepage coefficient (1 × 10-17 cm/s)

　　2. It has good heat and cold resistance, and its operating environment temperature is high at 110 ℃; Low temperature -70 ℃

　　3. It has excellent chemical stability and can resist corrosion from strong acids, alkalis, and oils, making it a good anti-corrosion material

　　4. It has high tensile strength, which enables it to meet the needs of high standard engineering projects

　　5. It has strong weather resistance, strong anti-aging performance, and can be exposed for a long time to maintain the original performance

　　6. It uses three separate feeders, and each layer of different ingredients can have unique properties, improving the engineering S performance of 1.5mmHg HDPE geomembrane.

　　7. Its overall performance, with strong tensile strength and elongation at break, enables it to be used in various harsh geological and climatic conditions. Adapt to uneven geological settlement with strong strain force.

　　8. The 1.5mm HDPE geomembrane (anti-seepage film) produced by our company is made of native plastic and carbon black particles without any preservatives. HDPE (high-density polyethylene) has been used in China to replace PVC as a raw material for food packaging bags and cling films. Our company's production is non-toxic, has good engineering performance, and has a wide range of applications.

　　HDPE geomembrane laying construction and installation

　　1) It should extend from the bottom to the high position, without pulling too tightly, leaving a margin of 1.50% for local sinking and stretching. Considering the actual situation of this project, the slope will be laid in a top-down sequence.

　　2) The longitudinal joints of adjacent frames should not be on the same horizontal line and should be staggered by more than 1M from each other.

　　3) The longitudinal joint should be at least 1.50m away from the dam foot and bend foot, and should be set on a flat surface.

　　4) Start with the back bottom of the slope first.

　　5) When laying the slope, the direction of the film should be basically parallel to the steep slope line.

　　*Slope laying control: Before laying the anti-seepage geomembrane on the slope, the laying area should be inspected and measured. Based on the measured size, the anti-seepage membrane that matches the size in the warehouse should be transported to the first phase anchoring ditch platform. During laying, a convenient method of "pushing and laying" from top to bottom should be adopted according to the actual conditions on site. In the fan-shaped area, it should be cut reasonably to ensure that both the upper and lower ends are firmly anchored.

　　*Bottom laying control: Before laying the anti-seepage geomembrane, the laying area should be inspected and measured. According to the measured size, the anti-seepage membrane that matches the size in the warehouse should be transported to the corresponding position. During laying, manual "pushing" should be carried out in a certain direction.
