本文以天津地铁3号线某区间软弱土地层联络通道施工为例,介绍了水平冻结加固施工技术在工程中的具体应用,文中重点介绍了冻结施工关键技术、冻结孔布置、开挖构筑施工技术及融沉注浆技术。实践证明,采用水平冻结法施工技术是科学合理的,既保证了地铁联络通道的施工安全,又保证了工程质量和进度,其施工方法对于同类工程具有一定的参考价值。
This paper takes the construction of the contact channel of weak soil strata in certain section of Tianjin Metro Line 3 as an example, introduces the concrete application of horizontal freezing reinforcement construction technology in the project, mainly introduces the key technologies of freezing construction, freezing hole layout, excavation construction technology And Shen Shen grouting technology. Practice has proved that the use of horizontal freezing method of construction technology is scientific and rational, not only to ensure the safety of the subway liaison channel construction, but also to ensure the quality and progress of the project, its construction methods for similar projects have some reference value.
