Abstract: The onsite assembly and welding for ship lift chamber is the key in the construction of ship lift.It is mainly restricted by the site limitation, poor construction conditions, tight construction period and other factors. It introduces a design of onsite assembly and welding for ship lift chamber including the modularized structure, hoisting in position, and setting of welding process. And it analyzes the design including technical characteristics, construction period and economy, safety and quality. The engineering practice indicates that the design can effectively ensure the construction quality, save the construction period, improve the work efficiency and guarantee the construction safety.
