AI Technical Summary
Traditional submerged pipe installation for water supply requires a large site and multiple underwater welding operations, resulting in significant site occupation and severe damage to the riverbanks of municipal parks.
The non-segmented floating pipe connection method is adopted. By installing a work box and roller trolley on the shore, the pipe is gradually pushed forward using the buoyancy of the pipe and airbag. Welding is completed on the shore, avoiding water operations. A waterproof work box is used to prevent river water from entering, creating a dry working environment.
It reduces the need for site space, lowers engineering costs, and minimizes environmental impact, making it suitable for immersed tube construction in confined spaces.
