Underground space and the underground passage between plots will greatly improve the convenience and multi-dimension of traffic.Before the underground passage is built,it is necessary to do a good job in supporting the underground structure.Based on a project in Hainan province,this paper introduces a connection construction technology between underground passage and existing foundation pit supporting structure in adjacent sea area,and provides practical experience for similar projects,and focused on analyzing construction technologies such as fertilizer tank backfilling,support piles,high-pressure rotary jet grouting piles,crown beams,drainage,and earthwork excavation.
