Geomembrane is widely used, and how to solve problems encountered during construction is also a problem. HDPE impermeable membrane is currently the most widely used HDPE geomembrane for sale for environmental protection engineering and anti-seepage, tailings, and sanitary landfills. It is an impermeable material made of high molecular polyethylene through blow molding or flat extrusion. Durability. HDPE geomembrane heat. The expansion and contraction deformation is large, so the amount of thermal expansion and contraction deformation of the material should be set aside during construction. The HDPE impermeable membrane is laid on the same day as possible, to minimize wrinkles and drag, and should not be pulled too tight, otherwise the stress due to local deformation will be too large and the HDPE membrane will be damaged. How to solve the problems of HDPE geomembrane thermal expansion and contraction and anchoring? You can refer to the data of HDPE geomembrane manufacturers. The seam treatment of geomembrane welding geomembrane is the key procedure of construction, which directly affects the operating life of the project. According to quality inspection, it is ideal to use thermal welding. (It can also be bonded with special glue.) The heat welding method is to heat the surface of the pe geomembrane to melt it, and then fuse it to integrate it. The geomembrane is best laid in a certain direction, and the geomembrane is pre-treated on both sides. Leave a certain non-adhesive layer of pe film and pet. When laying, adjust the geomembrane direction of each unit to facilitate the welding of the high quality aquaculture geomembrane of the two units. After the geomembrane is laid, it should be pressed with sand bags to prevent wind movement. The edge joints must be free of dirt, moisture, dust, etc. Before welding, adjust the two edges of the single film at the seam so that it overlaps a certain broadband, and it is flat and free of wrinkles. When welding, it is best to be welded by a technician with certain experience. Welding is done with a special welding machine. To adjust the temperature and speed, (also can be glued). Protection of HDPE membrane during the construction of leachate crushed stone drainage layer. The leachate drainage layer generally uses materials such as pebbles or gravel, and the thickness should not be less than 30cm. Due to the large landfill area, the amount of gravel paving is very large. How to solve the transportation and paving of gravel on HDPE membrane In the process, it is very important to prevent the problem of damage to the HDPE film. Adopt the operation method of zoning construction, each laying 4 pieces of film as a working unit, laying 5mm thick steel plate on the HDPE film as a material transportation channel, laying a gravel walkway with a thickness of more than 1.5 meters at a certain interval, and then using excavation on the walkway The machine spreads gravel from the inside out. Through the anti-leakage detection, this construction measure has a better protection effect on the HDPE film and rarely damages the HDPE film. How to solve the problems of HDPE aquaculture geomembrane factory price thermal expansion and contraction and anchoring? Geomembrane anchoring After the laying of the geomembrane is completed, anchoring is also the most important part of the project. In fact, there are many methods of anchoring: groove anchoring, nailing anchoring, expansion bolt anchoring, and fixing of embedded parts. Sewage tanks are usually fixed with embedded parts or expansion screw bars. The width of the bead is not less than 2cm, the thickness is not less than 2mm, the distance between the expansion bolts should not be greater than 600mm, and anti-corrosion measures should be taken in the exposed area of ​​the bead. The bolt diameter is not less than 4mm, and the spacing is not more than 0.5mm. During construction, first use the prepared sandbag to temporarily fix the film in place to prevent the strong wind from blowing and shifting the HDPE film, and then anchor the expansion bolt. If the embedded parts have been buried, you only need to use an extrusion welding machine to weld the film to the HDPE embedded parts.

When it comes to geotextiles, everyone is not unfamiliar. Of course, wholesale filament nonwoven geotextile are very widely used.
