　　HDPE geomembrane welding machine Jingheng tunnel waterproof membrane welding machine

　　Function introduction of geomembrane welding machine: Electric heating system: The heating temperature of the electric wedge adopts closed-loop control, and the temperature can be continuously adjusted. Adjust the thickness of the material to the corresponding pressure position for welding. Welding pressure regulation system: capable of continuous adjustment. Transmission system: It adopts dual wheel synchronous drive with upper and lower pressure rollers, and electronic continuously variable transmission control. The automatic control system is equipped with a speed generator to regulate the welding speed and maintain it constant, unaffected by load changes. Power is transmitted to the transmission/compression wheel through three-stage planetary gear reduction. The geomembrane welding machine is suitable for welding all hot-melt materials such as PE, PVC, EVA, HDPE, PP, etc. It is widely used in the construction of tunnels, railways, water conservancy, garbage landfills, underwater tunnels, high-speed railways, aquaculture, building waterproofing and other projects, and has received unanimous praise from the engineering community.

　　Geotextile is a common building material in our daily lives, mainly used for waterproofing in our buildings. The geomembranes we use now are all high-tech special materials because they have a very light weight and good extensibility, which are often used in our building waterproofing. Nowadays, we use its high waterproof performance in order to achieve its effectiveness. In daily life, when our earth dams suffer from serious water leakage, we use geomembranes to prevent water from passing through the dams and solve the problem of water leakage. Many times, our materials have very high tensile strength and strong ability to withstand water pressure. This way, when our dam body deforms, we can still allow water to pass through it. This is its major characteristic in use.

　　During the construction period, it is inevitable to encounter situations where a climbing welding machine is used to join the joints of the geomembrane. Generally, the construction team will choose people with good joint technology to complete this work. However, even so, errors may still occur. Below are some precautions for geomembrane joints: According to quality testing, using hot welding method is more ideal. The hot welding method is to heat the surface of the PE geomembrane to melt it, and then fuse it into one through pressure. The geomembrane should be laid along a certain direction, and a certain amount of PE film and PET non adhesive layer should be reserved on both sides of the geomembrane. When laying, the direction of each unit of geomembrane should be adjusted to facilitate the welding of the two units of geomembrane. After laying the geomembrane, it should be pressed down with sand bags to prevent wind movement. The edge joints should be free of dirt, moisture, dust, etc. When there are impurities, they must be cleaned before welding. Before welding, the two edges of the PE film at the joint should be adjusted to overlap a certain width, and it should be smooth and wrinkle free. When encountering insufficient length of geomembrane, longitudinal splicing is required. The transverse welds should be welded first, and then the longitudinal welds should be welded. If the distance between the transverse welds is greater than 50cm, they should form a T shape and not cross each other. When welding, it is best to have experienced technicians who use specialized welding machines for welding. The temperature and speed should be adjusted properly, and there should be no slipping or jumping of the weld seam. Adjacent geomembrane welds should be staggered and overlapped as much as possible. The nodes formed between the membrane blocks should be T-shaped, and cross shaped joints should be minimized as much as possible. Squeezing welding machines should be used to strengthen the intersection points of the longitudinal molds towards the welds. When using a climbing welding machine in the construction of geomembranes, special attention should be paid to ensure that the laying is not too tight, wrinkles are not allowed, and the joints are firm. Strictly follow the technical specifications for construction, and ensure the quality control of five aspects including preparation, laying, splicing, inspection, and backfilling.
