摘要/Abstract

摘要：

By analyzing the application cases of superlarge diameter shield machine in the world and taking China Shantou Gulf Tunnel and Shenzhen Chunfeng Tunnel construction for examples, the problems encountered in the research and development and construction are proposed and the key technologies to solve a series of problems, such as cutterhead maintenance and cutter changing technology under high soil and water pressure, boring in long fractured zone, are explored. More specifically, the technologies mainly involve cutterhead design, atmospheric cutter changing, main drive with telescopic and swinging function, reliable sealing system, antiblockage technique by applying double crushers, which are of great significance to the development and application of superlarge diameter shield machine.

关键词: superlarge shield machine, slurry shield, atmospheric cutter changing, double crushers, blockage

Abstract:

统计国内外超大直径盾构工程应用案例，并分析超大直径盾构设计选型时需考虑的关键因素，重点以汕头海湾隧道和深圳春风隧道超大直径盾构项目为依托，阐述超大直径盾构研发制造和施工中遇到的难题，探索解决高水土压力下刀盘维护及换刀、破碎地层长距离掘进等一系列难题的关键技术。主要从刀盘设计、常压换刀、主驱动伸缩摆动及可靠密封系统、防滞排双破碎机布置等方面开展针对性设计，对超大直径盾构的研制和应用推广有较好的意义。
