Construction method of foundation pit adjacent to subway tunnel
The invention provides a construction method of a foundation pit adjacent to a subway tunnel, and relates to the field of building construction. The foundation pit construction method comprises deep foundation pit construction and shallow foundation pit construction, and the deep foundation pit construction comprises the steps that firstly, earth and stone in the excavation range of the deep foundation pit are divided into a plurality of areas, the multiple areas are excavated one by one in a symmetrical construction mode, the areas are excavated downwards in sequence according to the layering sequence, supporting is conducted after each layer is excavated, and the shallow foundation pit is constructed after each layer is excavated; excavation of the next layer is conducted after supporting reaches the preset condition, and supporting construction is conducted after excavation of the deep foundation pit is completed; the shallow foundation pit construction comprises the steps that firstly, earth and stone in the excavation range of the shallow foundation pit are divided into multiple sections of areas, each section of area is supported, then the multiple sections of areas are excavated in an interval construction mode, and uplift-resistant construction is conducted immediately after excavation of each section of area is completed; through deep foundation pit construction and shallow foundation pit construction, the floating problem of the subway tunnel in the excavation process is solved, and normal operation of the subway tunnel is maintained.
本申请提供一种紧邻地铁隧道的基坑施工方法，涉及建筑施工领域；基坑施工方法包括深基坑施工和浅基坑施工，深基坑施工包括：先将深基坑开挖范围内的土石方分为多块区域，以对称施工的方式对多块区域逐块开挖，且每一块区域按照分层的顺序依次向下开挖，每开挖一层后进行支护，支护达到预设条件再进行下一层的开挖，待深基坑开挖完成后进行支护施工；浅基坑施工包括：先将浅基坑开挖范围内的土石方分为多段区域，对每段区域均进行支护，然后以间隔施工的方式对多段区域分别开挖，每段区域开挖完成后立即进行抗隆起施工；本申请通过深基坑施工和浅基坑施工，解决了在开挖过程中地铁隧道的上浮问题，维护地铁隧道的正常运行。
