Material Test and Technology of Advanced Grouting with Small Pipe for Hujialou Station of Beijing Subway Line 10 |
| |
| Abstract: | The major structure of Hujialou station of Beijing Subway Line 10 has begun excavating.The arch layer is composed of fine sand,round gravel and clay with high moisture content,with poor stability.Through experimentally application of cement-water glass grout and modified water glass grout that are mixed with different properties for different layers to stop water and reinforce and optimization of grouting process,the efficiency is improved and control range and construction safety are ensures. |
