Description

A lock end template and construction method adapted to double water-stop copper sheets Technical Field

[0001] This invention relates to the field of lock waterstop copper sheet construction, and in particular to a lock end template and construction method adapted to double waterstop copper sheets. Background Technology

[0002] With the rapid development of waterway engineering in my country, the upgrading of waterway functions is in full swing. Among them, lock engineering is the key to the upgrading of waterway functions. At present, U-shaped locks account for a large proportion of the locks in China. The lock chamber sidewalls have high waterproofing requirements. In order to meet the waterproofing requirements, multiple water-stop copper sheets are often installed at the joints of lock sections. However, the water-stop copper sheets penetrate through two lock sections, which makes it impossible for the lock chamber end formwork to form a whole, resulting in low construction quality and efficiency.

[0003] To address this challenge, the construction and installation design of the water-stop copper sheet was optimized, allowing it to be more easily embedded into the pre-set grooves. This reduced the amount of on-site welding and fixing work, significantly improving installation speed and accuracy. Combined with a specialized hoisting device, the installation of the water-stop copper sheet became safer and more efficient. Featuring a precise positioning system and automatic adjustment function, it can quickly and accurately hoist the water-stop copper sheet into place according to the specific dimensions and location of the lock section, while ensuring a tight bond between the copper sheet and the concrete. This effectively improves the waterproofing performance of the lock chamber and the overall construction quality. Summary of the Invention
