摘要
以长沙地铁南湖路站南端大跨度、大厚度的盾构预留孔洞为依托,研究贝雷架模板支撑体系在盾构隧道预留孔洞中施工技术及稳定性.构建了以贝雷架模板为基础的支撑体系,设计了贝雷架支撑体系施工方案,并对贝雷架模板支撑体系进行了结构强度验算.结果表明,贝雷架模板支撑体系施工方案不仅保证了支撑体系的结构强度,还具有施工简便、经济环保等优点,为此类工程施工提供了参考.
Relying on the large-span and large-thickness reserved holes of the shield tunnel at the south end of Changsha Metro Nanhu Road Station, the construction technology and stability of the Bailey framework support system in the reserved holes of the shield tunnel are studied. In this paper, the support system based on the Bailey frame, expounds its construction plan, checks and calculates its structural strength. Results show that the construction plan of the Bailey framework support system designed in this paper not only guarantees the structural strength of the support system, but also has the advantages of simple construction, economy and environmental protection, and provides a reference for the construction of such projects.
