Design and construction of the foundation pit support for Wangjiaguanzhuang old village reconstruction

Abstract:

This paper introduces the design and implementation of the foundation pit support for the Wangjiaguanzhuang old village reconstruction project in Jimo District of Qingdao City. The project is characterized with complex stratum conditions, rich groundwater, and is close to Shipeng Reservoir with complicate environmental conditions. Through the successful implementation of technical measures such as the soil nailing wall and high pressure jet grouting pile water cut-off curtain, foundation pit dewatering, good foundation support has been achieved, ensuring the safety of foundation pit excavation and foundation construction in the underground garage; and the construction quality meets the relevant technical requirements.
