哈大客运专线大连北站站房工程钢筋混凝土结构施工中,梁板截面尺寸和支撑高度均较大,属高支模,通过方案比选,确定采用安德固60系列支撑体系。对施工方案进行设计,尤其对地下通廊、南北站房和高架候车厅楼板部位进行施工设计。介绍了施工工艺流程及预压试验。在实施预压时,对支撑体系进行严格控制,通过监测,沉降及变形满足方案要求。实践证明,支撑体系满足施工要求。
In Harbin-Dalian Passenger Dedicated Railway Line, during the construction of reinforced concrete structures of Dalian North Station, the cross-sectional dimensions and supporting height of beam plates are large and belong to high-support mold. Through the comparison and selection of schemes, it is determined that Andegu 60-series supporting system is adopted. The design of the construction program, especially for underground corridors, North and South Station room and elevated waiting room floor construction site design. The construction process and preloading test are introduced. In the implementation of preload, the support system for strict control, monitoring, settlement and deformation to meet the program requirements. Practice has proved that the support system to meet the construction requirements.
