  • Chained wall of precast concrete piles is an innovative foundation pit retaining structure with both earth retaining and water stopping functions. Based on a deep foundation pit project in soft soil area of Ningbo, the difficulties and key technologies in design and construction of the chained wall were summarized, and the chained wall was compared with traditional bored pile in terms of construction convenience and environmental protection. The results show that the chained wall has the advantages of safety, efficiency and environmental protection, and it is suitable for foundation pit engineering in soft soil area.
