Shanghai tunnel geomembrane climbing welding machine waterproof and anti-seepage welding equipment

Description :

　　The significance of climbing welding machines for engineering is enormous. Some machines cannot be used during construction because an important factor in engineering is the difficult condition of leak prevention facilities for water and electricity. A machinery that cannot be waterproof in engineering may pose safety hazards. If there is an electric shock to the construction personnel, it will cause huge losses to both the construction unit and the construction personnel's families. Therefore, it promotes the birth of some targeted machinery, such as climbing welding machines. It is necessary for the construction unit to purchase and conduct safety inspections on climbing welding machines. There are currently multiple models of climbing welding machine mechanical equipment, and different models are suitable for different uses. Our customer service personnel will recommend models of mechanical equipment to buyers based on their usage needs to avoid the occurrence of some problems.

　　In the construction of tunnel waterproofing engineering, the primary attention is to control the quality of the suspension of waterproof boards. The current tunnel adopts the spray anchor construction method based on the New Austrian Method principle. After excavation, concrete is sprayed first for initial support as the primary lining, followed by the laying of waterproof boards and the construction of secondary lining. The laying of waterproof boards is carried out by using nail guns to drive cement nails to suspend the waterproof boards. In the initial stage, the sprayed concrete is relatively thin and the spraying thickness is uneven. When encountering areas with thin spraying thickness, it is difficult to drive the cement nails in, which can easily rebound and injure people, especially the nail caps. The exposed parts of the cement nails are sharp and can easily puncture the waterproof boards, causing them to fail. Therefore, it is necessary to pay close attention to the monitoring of the construction process during the suspension of waterproof boards. In addition, sufficient attention must be paid to the welding quality control of waterproof boards. In the past, waterproofing boards were generally welded using hot air blowers and soldering irons, making it difficult to ensure welding quality. Although double welds were used, it was still difficult to ensure that the welds did not leak. The climbing welding machine currently used can automatically form double welds, ensuring welding quality from a process perspective. According to the current sampling inspection results of tunnel construction, all welds welded with climbing welding machines can generally meet the inspection requirements in the inflation test, indicating that the quality of waterproof boards welded with climbing welding machines is relatively stable and the effect is good.
