[0002] A deep foundation pit refers to an engineering project with an excavation depth exceeding 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation. The foundation pit support system is a temporary structure and is no longer needed after the underground engineering construction is completed.

[0003] Anchor support refers to a reinforcement support method used in surface engineering projects such as slopes, deep rock and soil foundation pits, and underground chamber construction such as tunnels and mines. It has the advantages of low cost, good support effect, simple operation, flexible use, and less construction clearance space occupied.
