Subway transfer node area deep foundation pit construction method
The invention relates to the technical field of deep foundation pit construction, in particular to a subway transfer node area deep foundation pit construction method. The transfer node area comprises an expansion section, a pipeline relocation section and a main body connection section; a temporary partition is arranged on the side portion of the main body connecting section and used for separating the transfer joint area from the main body section of the first subway line, a concrete supporting system is adopted for the expansion section, and a concrete and steel support mixed supporting system is adopted for the pipeline moving and changing section and the main body connecting section; the deep foundation pit construction method comprises the steps that S1, traffic defibering and pipeline relocation are conducted; and S5, foundation pit excavation and supporting are conducted, specifically, a vertical layering and longitudinal segmentation combined mode is adopted for foundation pit excavation and supporting, the sequence of longitudinal segmentation is an expansion section, a main body connecting section and a pipeline moving and changing section, and when foundation pit excavation and supporting of the pipeline moving and changing section are conducted, temporary partitions with the corresponding depths are synchronously dismantled, so that idling of workers is avoided, and the construction efficiency is improved. And the overall construction time is greatly shortened.
本申请涉及深基坑施工技术领域，特别涉及一种地铁换乘节点区域深基坑施工方法。换乘节点区域包括扩大段、管线迁改段、主体连接段；主体连接段侧部设置临时隔断，用于将换乘节点区域与第一地铁线路的主体段隔开，扩大段采用混凝土支撑体系，管线迁改段、主体连接段采用混凝土与钢支撑的混合支撑体系；深基坑施工方法包括：步骤S1：交通疏解、管线迁改；步骤S5，基坑开挖与支撑：基坑开挖与支撑采用竖向分层、纵向分段相结合的方式，纵向分段的顺序先后为扩大段、主体连接段、管线迁改段，在进行管线迁改段基坑开挖与支撑时，同步拆除对应深度的临时隔断，以避免窝工，极大的缩短整体施工时间。
