摘要
针对温州市软土地区隧道开挖过程中遇到过河段的工况,隧道开挖施工存在难点,施工过程中采取明挖隧道过河段模袋砂围堰施工技术。重点介绍了明挖隧道过河段模袋砂围堰施工技术的围堰设计、材料选择和施工关键技术,并在此基础上结合实际情况进行技术改进。
According to the working condi t ions of tunne l s encountered in the process of tunnel excavation in Wenzhou so f t soil area,it is difficult to excavate and const ruct t unnel s . In th e process of construction,the construction t echnology of mo ld bagged cofferdam crossing the river is adopt ed . Cof f e r dam design,materials selection and construction key t ec hnologies fo r digging the construction technology of bagged s and c of f er dam in the tunneling section of the Ming dug excavation sect i on,a nd based on this,the technical improvements ar e made accor ding to the actual conditions.
