浅析盾构法隧道二次注浆技术——以金陵石化南京长江盾构工程为例

Analysis on Tunnel Secondary Grouting Technique Using Shield Method——By Taking Nanjing Changjiang Shield Project of Jinling Petrochemical Co. for Example

摘要: 在盾构法隧道穿越工程中，二次注浆对于隧道成型质量至关重要。以南京盾构隧道二次注浆工程为实例，通过介绍二次注浆适用范围、注浆作用、浆液配比、注浆压力、注浆量、注浆顺序和质量控制及注浆效果检查等方面，系统阐述了盾构法隧道二次注浆技术。

Abstract: In tunnel crossing project using shield method, the secondary grouting was vital for tunnel forming quality. By taking Nanjing secondary grouting of shield tunnel project for example, the suitable scope of secondary grouting, grouting effect, the ratio of slurry, grouting pressure, grouting amount, grouting sequence and its quality control and grouting effect inspection and so on were introduced, and the technology of secondary tunnel grouting using shield method was systematically denoted. It provides reference for secondary tunnel grouting using shield method.
