摘要
地下空间地下通道连通将极大提高交通便捷性、多维性,而建设地下通道前,需做好地下结构的支护工程。依托海南省某工程项目,介绍了一种邻海地区地下通道与既有基坑支护结构连接施工技术,并重点分析了肥槽回填、支护桩、高压旋喷桩、冠梁、降排水及土方开挖等施工技术。
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.
