Research on Construction Technology of Frozen Linkage Channel in Deep Water-rich Soft Soil Layer of Land-sea Interaction

摘要

经济社会的发展以及人们交通需求的不断上升推动地下轨道交通网络完善。盾构隧道间联络通道的安全、高效施工也成为了施工界十分关注的焦点问题。而饱和软土、砂土等相应复杂地质条件下，联络通道施工难度是相对较高的，这时则可通过水平冻结法的应用提高联络通道施工质量和效率，保障施工安全，可紧抓施工前期准备阶段、冻结系统施工与积极冻结阶段、开挖与永久结构构筑阶段、维护冻结与融沉控制阶段四个关键阶段，分析冷冻法在联络通道施工中的应用要点，加强技术控制，提高施工质量。

Abstract

The advancement of socio-economic development and the growing transportation demands have driven the refinement of underground rail transit networks. The safe and efficient construction of inter-tunnel connection passages has become a critical focus in the construction industry. Under complex geological conditions such as saturated soft soil and sandy soil, the construction of these passages presents significant challenges. The application of the horizontal freezing method can enhance construction quality and efficiency while ensuring safety. This approach emphasizes four key phases: preparatory stage, freezing system installation and active freezing, excavation and permanent structure construction, and maintenance of freezing and settlement control. This paper analyzes the key aspects of the freezing method in connection passage construction, strengthens technical oversight, and improves construction quality.
