山岭区中短隧道“零开挖”单向出洞施工技术
|
摘要
以广佛肇高速公路谷尾咀隧道出洞施工为例,在确定出洞方案的基础上,详细介绍了"零开挖"单向出洞的关键施工技术,其中涉及双层超前小导管支护、保留核心土三台阶开挖等内容,不仅可最大限度地保护生态环境,而且节约了施工费用。
Taking the construction of Guweizui tunnel exit of GuangFoZhao highway as an example, on the basis of determine the exit hole plan, this paper introduced the key construction technology of "no excavation" one-way for exit hole, which involves the double leading small catheter support, retaining the core soil three steps excavation, etc., which not only can maximize the protection of the ecological environment, but also can save the construction cost.
