摘要：在进行消防水池深基坑支护施工前，根据工程现场条件、岩土体分布情况，结合工程造价、施工工艺和材料设备准备等综合考虑，文章以长桥卫生院医技综合楼建设项目为例，项目消防水池基坑支护结构采用较为安全经济合理的土钉墙支护+喷锚支护体系。有效地控制了深基坑在开挖过程中围护结构的变形和位移，减少了对周边建筑物及自然山体的影响，实现了深基坑在施工过程中的安全与稳定，取得了较大的经济效益，对类似深基坑工程施工具有一定的参考价值。
Abstract: Before carrying out the deep foundation pit support construction of the fire water pool, based on the site conditions,distribution of rock and soil mass, and comprehensive considerations of project cost, construction technology, and material and equipment preparation, this article takes the construction project of Changqiao Health Center Medical Technology Comprehensive Building as an example. The fire water pool foundation pit support structure of the project adopts a relatively safe, economical and reasonable soil nail wall support+spray anchor support system. It can effectively control the deformation and displacement of the retaining structure during the excavation process of deep foundation pits, reduce the impact on surrounding buildings and natural mountains, achieve the safety and stability of deep foundation pits during construction, and achieve significant economic benefits. It has certain reference value for similar deep foundation pit construction projects.
