Optimization of Scheme for Deep Foundation Pit of Subway Pile Anchor with Adjacent Shaft

Subway station is located in the center of the city, the station construction process, taking into account the duration, environment and other factors, more use of ming excavation construction, urban underground pipe network and subway station cross more. How to ensure the safety of construction and reduce the impact on the surrounding pipeline and surrounding buildings in the construction process of subway station has become a difficult point of subway construction. This paper introduces the position relationship between pile anchor form and adjacent power shaft, analyzes the support form of power shaft and pit, determines the strengthening support measures of the station foundation pit according to the actual situation of the site, economic benefits and safety quality requirements, provides a strong guarantee for the safety of the building, and also provides an effective case study for the construction of the follow-up station.
