隧道衬砌施工缝止水带施工工艺探讨

摘要

Water stop construction technology for construction joints and settlement joints in tunnel linings is currently one of the most sensitive problems in the construction of waterproofing and water drainage. This paper discusses the connection method, joint strength, and embedded depth of water stops, as well as the fixing and protecting of their exposed height. It also presents water stop construction technology for lining sections with and without reinforcement.%隧道衬砌施工缝和沉降缝的止水带施工工艺,是目前防排水施工中的一大难点.文章对止水带连接方式、连接强度和止水带顺直、埋入深度、外露高度等的固定和保护进行探讨,并提出无钢筋衬砌段和钢筋衬砌段的止水带施工工艺,消除了止水带施工通病,可为隧道工程的止水带施工提供借鉴.
