摘要
大连湾沉管隧道采用了新型最终接头形式和施工工法——顶进节段法。为了解决传统的止水带无法满足该新型工法特殊环境下防水要求的问题,设计人员采用了可伸缩止水带、注浆止水带及其他防水措施。本文着重介绍顶进节段法的构造特点、防水设计,供同类工程作参考。
A new type of final joint and construction method——jacking segment method,are adopted in Dalian Bay immersed tunnel.In order to solve the problem that the traditional water stop cannot meet the waterproofing requirements of the new construction method under the special environment,the designers adopted retractable water stop,grouting water stop and other waterproofing measures.This paper mainly introduces the structural characteristics and waterproofing design of jacking segment method,which can be used as a reference for similar projects.
