Title Geomembrane splicing method generally selects hot melt welding method for engineering construction
Description Under normal circumstances, composite polyester geogrid factory price is the most commonly used raw material for waterproof layer in the process of water conservancy engineering building renovation. For the transformation of engineering projects, the most important thing is the splicing quality, which is an important factor that determines the success or failure of the characteristics of the geomembrane waterproof layer. What should be done during the welding process to improve the repair quality? How to improve the welding quality of composite uniaxial plastic geogrid manufacturers? How to solder? In engineering construction, the splicing method generally uses the hot melt welding method. The membrane and membrane are usually welded by a dual-drive self-propelled geomembrane welding machine. The total lap width of welded steel bars is 12 cm. There is a 12 mm wide opening between the two welds. The fabric and fabric are sewn by a hand-held coating machine and T-shaped polyester thread. Note that before the welding is announced, test welding should be performed according to the atmospheric characteristics of the construction site, and the walking speed and welding temperature should be determined. During the whole construction process, the walking speed of the automatic welding machine should be controlled at 0.7~1.3m/s, and the welding temperature should be controlled at 260~280℃ to ensure that the welding quality of the waterproof geotextile exceeds the design plan. Before welding, it is best to place this long wooden board at the joint of the high quality uniaxial plastic geogrid to facilitate welding. The hot-melt welding machine moves on a flat base surface to ensure the welding quality. In addition to the quality of raw materials, if you want to further improve the characteristics of waterproof geotextiles, you must work hard during construction. The chief engineer will provide convenience for project construction and ensure the quality of splicing. Waterproof geotextiles are usually used in large quantities to reduce the amount of stitching on site. Before the construction of the project, according to the needs of the width of the raw materials and the length of the site, cut out a suitable length in the factory, splice it into blocks that meet the specified specifications, and fold it into a roll. In order to facilitate the lateral connection of the uniaxial plastic geogrid for sale, a non-composite layer of about 10 cm is embedded on both sides. The damage of the geomembrane during welding and cutting mainly occurs at the weak part of the foundation where the welding zone is connected to the geomembrane. Therefore, people should attach great importance to the welding construction site.
