盾构隧道同步注浆施工中存在的问题及对策

Analysis on synchronous grouting construction problems and countermeasures of shield tunnel

简述了地铁盾构隧道同步注浆的背景,分析了在盾构隧道同步注浆施工中存在的问题,并对此提出几点对策,以减少同步注浆施工过程中存在的问题,确保同步注浆的效果。

The paper describes the background of the synchronous grouting of subway shield tunnel,analyzes synchronous grouting problems of the shield tunnel,and puts forward some countermeasures,with a view to reduce synchronous grouting construction problems and to guarantee the synchronous grouting effect as well.
