　　Automatic walking HDPE geomembrane welding machine, tunnel climbing welding machine manufacturer

　　The basic three points in the operation of a climbing welding machine are: 1. Before overlapping the waterproof board, the end should be trimmed, and the surface of the waterproof board at the joint surface should be cleaned thoroughly. 2. In the work, it is required to determine the welding temperature of the climbing welding machine according to the walking speed of the equipment, in order to avoid welding coke and welding penetration. 3. Before welding, it is necessary to align the waterproof board according to the control line, the distance of welding, and whether the surface is clean. During walking, it is necessary to ensure uniform speed and avoid deviation. The waterproof board climbing welding machine can meet the welding requirements of different thicknesses and is suitable for all hot-melt materials such as PE, PVC, HDPE, EVA, PP, etc. The temperature control part of this series of welding machines adopts PID automatic constant temperature control, with high control accuracy and small temperature fluctuations. The speed control part adopts pulse width modulation PWM automatic voltage and speed stabilization circuit; Driven by DC servo motor, with high output torque and smooth walking; Can maintain a constant speed during climbing, vertical crawling, and changes in road load. This series of welding machines has high performance, easy operation, high welding efficiency, strong reliability, and is highly praised by users. Product applications: landfill anti-seepage, waste liquid discharge pool, public works, building foundation geomembrane, waterproofing, mine waterproof lining, reservoir, irrigation ditch, dam anti-seepage membrane, aquaculture pond, swimming pool lining, oil storage tank anti-seepage, chemical reaction tank, sedimentation tank.

　　The connection method of geomembrane is generally welded using a geomembrane climbing welding machine, which has a better welding effect than adhesive bonding. Below, we will talk about the preparation work to be done before the construction of the geomembrane climbing welding machine: foundation treatment: clean the surface of the geomembrane laying, requiring a flat substrate, solid soil, no unevenness, cracks, sharp objects, stones, iron wires, wooden sticks, etc. The grass and tree roots within the anti-seepage range should be removed, and herbicides should be sprayed on weeds. On the contact surface with the membrane, lay a layer of sand or clay with small particle size as a protective layer, and the thickness of the protective layer should not be less than 30cm. The temperature control part of the geomembrane climbing welding machine adopts PID automatic constant temperature control, with high control accuracy and small temperature fluctuations. The speed control part adopts pulse width modulation (PWM) automatic voltage and speed stabilization circuit; Driven by DC servo motor, with high output torque and smooth walking; Can maintain a constant speed during climbing, vertical crawling, and changes in road load. The Jinyin geomembrane climbing welding machine has stable performance, easy operation, high welding efficiency, strong reliability, and is highly praised by users. It has been widely used in national projects such as the Qinghai Tibet Railway, the South to North Water Diversion Project, and the Qinling Tunnel.

　　In the construction of public and railway tunnel projects, welding construction of waterproof boards, waterstops, etc. is required. Waterproof boards and waterstops are generally made of boards or strips of certain specifications and sizes when they leave the factory, and need to be sealed and welded during construction. According to the "Acceptance Standards" for new tunnel construction issued by the Ministry of Railways and the Ministry of Transport, the current commonly used manual hot welding or adhesive welding methods cannot guarantee the reliability of construction, and have high labor intensity and low production efficiency.
