Abstract

The effect of the grouting consolidation in waterrich sandy cobble strata in Chengdu is poor. Simulation tests are made in laboratory and verifications are made in the job site. The traditional Soletanche grouting consolidation technology is optimized in terms of equipment structure, grouting procedure and grouting material. In the end, the grouting consolidation reliability is improved, the grouting consolidation effect is guaranteed and the risk of the buildings and pipelines is reduced. 

Key words： Chengdu Metro; waterrich sandy cobble strata; Soletanche grouting; combination of fine and coarse materials
