盾构法隧道施工中盾尾刷的优化与保护

Shield tunneling optimization and protection shield tail brush

随着盾构机和盾构技术的逐渐发展和进一步改革完善,盾构施工法已经广泛使用在大中型城市地下铁道和隧道工程的施工中,并且发挥着越来越重要的作用。在运用盾构法施工时,盾尾刷密封的程度将对整个工程的质量、施工安全和工程工期起着决定性作用。本文结合某隧道工程施工时运用的盾构法施工技术,分析了盾尾刷的优化和保护措施。

With the gradual development of TBM and Shield technology and further reform and improve the shield construction method has been widely used in the construction of medium-sized urban underground railway and tunnel project, and is playing an increasingly important role. In the use of shield construction, the degree will shield tail brush seal quality, construction safety and project duration plays a decisive role in the entire project. In this paper, the use of construction techniques Construction of a tunnel project shield, analysis and optimization of protection shield tail brush.
