隧道工程盖挖法施工技术

Construction Technology of Tunnel Cover Excavation Method

结合珠海某隧道工程下穿南琴路盖挖段施工技术方案,通过对盖挖法关键施工工序的研究,深入剖析分层支护和开挖所遇到的问题,并根据现场施工条件逐一制定应对措施,确保了施工期间南琴路的交通顺畅和施工安全,提高了施工效率,加快了施工进度,实现降本增效、安全可靠的目的。

Combined with the construction technical scheme of the cover excavation section of a tunnel project under Nanqin road in Zhuhai,through the research on the key construction procedures of the cover excavation method,deeply analyzes the problems encountered in layered support and excavation,and formulates countermeasures one by one according to the on-site construction conditions,which ensures the smooth traffic and construction safety of nanqin road during the construction period,improves the construction efficiency,speeds up the construction progress,and realizes the purpose of reducing cost,increasing efficiency,safety and reliability.
