盾构端头加固是盾构始发、到达技术的重要环节,圆砾层进行盾构端头加固的设计及施工有其特殊性,介绍了在圆砾层采用连续墙加袖阀管注浆工法进行端头加固的工程设计实例,为盾构在类似地层进行端头加固设计提供借鉴。
The shield end reinforcement is an important part of shield starting to arrive at the technology. The design and construction of the shield gravel reinforcement for the round gravel layer have their particularity. The application of the continuous wall plus sleeve valve grouting in the round gravel layer Engineering method of end reinforcement project design examples for the shield in similar strata for end reinforcement design to provide reference.
