Abstract: Deep foundation pit refers to the excavation depth of more than 5m (including 5m), or although the depth is less than 5m, but there are complex factors to the geological conditions, surrounding environment and underground pipelines or the adjacent buildings (construction) have safety impacts Earthwork excavation,support and precipitation works. As an industry prone to safety accidents, the construction industry has become one of the industries that the country pays attention to in the process of managing safety production problems. This article analyzes the construction safety issues of deep foundation pits in construction projects and discusses deep foundations The characteristics of the pit engineering and the importance of safety supervision,and taking the Yanxiang Hotel reconstruction project as an example, discussed the effective measures of safety management and quality management of the deep foundation pit construction site of the construction project.
