【摘要】 如何对硬岩隧道(洞)施工中使用的TBM进行设计选型?相信这是每个工程业主和设计院都需要面对的问题。通过对硬岩隧道(洞)掘进中,支撑式和双护盾式TBM的施工方法及设备功能包括对地质的适应性以及初期支护与混凝土衬砌型式、不良地质地段处理方法、出碴运输方式、环境影响等进行比较,并结合辽宁省大伙房输水一期工程输水隧洞施工中TBM的工程实践,提出了弥补支撑式TBM开挖和衬砌不能平行作业的改进构想,提出了采用栈桥式仰拱模板台车和全环内通式模板台车的施工方法。通过改进,可实现一模养生、一模浇注、第三模移动框架梁的作业工序。更多还原

【Abstract】 The authors compared the gripper TBM and double shield TBM for driving through hard rocks in respect of working mode and equipment functions including:adaptability to geology,types of primary support and concrete lining,treatment of poor geological sections,mucking and transport mode,impact on environment,etc.,and incorporating the TBM practice in Liaoning Dahuofang water-diversion tunnel first phase project,put forward the ideas for improving the defect of gripper TBM not permiting parallel operation of excavation and lining,propose to adopt trestle bridge invert mould jumbo and lining mould jumbo with internal passage in the construction which helps to realize curing in the first mould,casting in the second mould and shifting frame beam over the third mould.更多还原
