Abstract:Kunming Chenggong first phase of rail transit stations civil works, the main structure of the standard section thickness of side wall 700mm, headroom platform layer 6.45m, concourse level headroom 4.65m, a side wall of the concrete pouring a large amount of parties. Template for the unilateral side wall formwork, the traditional difficulties with Full Support systems exist concrete pouring, curing difficult, templates and long life cycle support issues such as turnover, the use of unilateral triangular back support system can effectively care template avoid the above problems. To ensure the quality and duration of construction safety, construction, calculated before the detailed design and organization of the planning, construction strict construction management and quality control to the station to achieve quality and efficient construction of the main structure for future reference for similar projects.
