环保型同步注浆浆液的施工实践

Construction Practice of Environmental Friendly Synchronized Grouting Liquid

介绍了应用于上海青草沙原水过江管工程盾构隧道施工的一种新型环保型同步注浆浆液。该浆液具有大比重、高抗剪、低稠度等优良性能以及更加良好的抗地下水及抗稀释性能,特别重要的是,该浆液还解决了该工程对周围环境(原水地周边地下水质)保护的技术难题。

It introduces a new environmental friendly synchronized grouting liquid,which is applied in the Shanghai Qingcaosha Raw Water Tunnel.This grouting liquid is featured by large specific density,high shear resistance,and low consistency,better waterproofing and dilution resistance.And it resolves the technical difficulty in environmental (water quality) protection at the surrounding area.
