暗挖法组合运用整环拆除盾构管片的实例解析
摘要:地铁建设作为一项大型长距离线性工程项目,工期风险在近年来日渐突出,加站、减站、缓建车站屡见不鲜,因此各种工法的组合运用,灵活解决由于方案调整带来的新问题,从而在满足运营功能的前提下有效控制工期,是目前多条地铁线路亟待解决的问题。以北京地铁10号线二期工程六里桥站—马官营站(缓建)—莲花桥站区段为工程实例,详细解读了在盾构先行掘进、实现洞通铺轨之后,通过工法的组合运用实施既有隧道管片拆除、暗挖施工风道的方案研究及实施方法。对于同类工程实施及暗挖施工缓建车站的可行性研究,具有借鉴意义。
Abstract:Subway construction as a large long linear engineering project, the risk of time limit for a project is increas ingly prominent in recent years, adding station, canceling station or postponing station is common. So the combination using of various excavation method is an urgent needing, to solve the new problems caused by the plan adjustment, to meet the operating function under the premise of effective control time limit for a project. Based on Beijing subway line 10 second phase Liuliqiao station--Maguanying station (delayed) Lianhuaqiao station interval for the engineering example, this paper detailed interprets the method of shield segment removed and Air duct implementation after the shield tunneling ahead and track-laying. For similar project and feasibility study on implementation of postponed station, it has the reference significance.
