Scope

Main technical content: ① This technical specification is formulated to ensure the safety, applicability, technological advancement, economic rationality, and quality of foundation pit support projects in the Urumqi area, while promoting green environmental protection. ② This technical specification applies to the investigation, design, construction, inspection, excavation, monitoring, and maintenance of temporary foundation pits under general geological conditions. For special soil or rock foundation pits such as fill soil, collapsible soil, saline soil, expansive soil, permafrost, and soft soil, this technical specification should be applied in conjunction with local engineering experience. Similar projects outside of construction engineering can refer to and implement it accordingly. ③ The investigation of foundation pit projects, the design of foundation pit support systems, and the construction and excavation of foundation pits should be carried out by comprehensively considering factors such as engineering geological conditions, hydrogeological conditions, the size of the foundation pit, the requirements of the surrounding environment, the requirements of the main underground structures, seasonal changes, construction conditions, and the service life of the support structures, with the aim of adapting to local conditions, selecting appropriate types, optimizing designs, ensuring meticulous construction, and implementing strict monitoring. ④ The main contents include: General Principles, Terms and Symbols, Basic Provisions, Slope Method, Support Structures, Soil Nail Walls, Groundwater Control, Monitoring, Safe Use and Maintenance of Foundation Pits, and Appendices.
