Geomembrane Caution: Do not drag in the transport process, pull hard to avoid sharp objects stabbed. 1, the bottom should be extended to high geomembrane direct prices, do not pull too tight, should leave more than 1.50% of the increase, to prepare local subsidence stretch. Taking into account the actual situation of the project, from top to bottom of the slope to take the laying sequence; 2, two adjacent longitudinal joints should not be in a horizontal line, should be staggered over 1m; 3, the vertical joints should distance foot dam, curved legs at 1.50m above, should be located in the plane; 4, after the end of the first slope field; 5, when the slope laying show the film to be substantially parallel to the direction of maximum slope line. Geomembrane welding 1. Hot Wedge Welder welding process is divided into: adjustable pressure set temperature set speed lap weld inspection loading film into the machine to start the motor pressure welding. 2. seams without oil, dust, HDPE geomembrane lap segment surface sediment and other debris should not clip when debris must be cleaned before welding. 3. Welding day begin, you must first try to weld samples at the scene of a 0.9mm × 0.3mm, the lap width of not less than 10cm, and peel and shear test Rally scene, after passing the sample, you can use that time to adjust Good speed, pressure, temperature formal welding. Be marked on the sample date, time, ambient temperature. Hot wedge welder in the welding process 15,953,851,088, to be ready to pay attention to the operation of the welding machine, according to the actual situation at the scene to fine-tune the speed and temperature. 4. Weld requirements neat, attractive, not a slip welding, jump away phenomenon. 5. In the event of geomembrane long enough, you need to splice length, should first transverse weld is good, then welded longitudinal seam, the lateral distance greater than 50cm should weld a T-shaped, can not cross. Geomembrane function 1, set the action in one of seepage and drainage, along with features such as isolation and reinforced. 2, high composite strength, high peel strength, high puncture strength. 3, drainage capacity, friction coefficient, low coefficient of linear expansion. 4, anti-aging performance, adapt to a wide range of ambient temperatures, stable quality. 1. laying before laying Geomembrane Geomembrane qualified acceptance by the appropriate civil documents. 2. Geomembrane before cutting, should accurately measure its relative size, and then press the actual cutting, generally should not be cut by the icon size, should by piece number, a detailed record of the special form. 3. laying of HDPE geomembrane should be sought to weld at least, under the premise of guaranteeing quality geomembrane, try to save raw materials. But also easy to ensure quality. The seams between the membrane and the membrane lap width is generally not less than 10cm, usually arranged in a direction parallel to the weld maximum slope, that are arranged in the direction of the gradient. 5. At the corner and deformity usually lots should be to minimize the short length of the seam. In addition to special requirements, the slope is greater than 1: 6 slope within slope from the top or the stress concentration range of 1.5 m area, as no welds. 6. Geomembrane laying, you should avoid artificial geomembrane wrinkles national standards, at low temperature, should be taut, paved. 7. After completion of the laying Geomembrane, should minimize the membrane surface walking, moving tools, who can cause harm to the HDPE film objects should not be placed on the membrane or membrane carrying walking, so as to avoid membrane damage caused by the accident.
