盾构法隧道二次注浆施工工艺研究

通过地铁盾构法隧道二次注浆工程实践,从适用范围、技术要求、浆液配比、注浆压力控制、注浆量、注浆顺序和质量控制等方面详细介绍了深圳地铁二期工程盾构法施工二次注浆施工技术,对今后盾构施工进行二次注浆有很好的参考作用。

Research on construction craft of secondary grouting of shielding tunnels

According to the engineering practice of secondary grouting of shielding tunnels,the paper introduces the secondary grouting construction technique of the shielding method in the second period project of the subway from the applied scope,the technical requirement,the proportion of slurry,the control over grouting pressure,the grouting volume,the grouting sequence,and the quality control,so as to have the reference for the secondary grouting construction in the shielding construction in future.
