Slurry grouting
WebbThe slurry as 3 functions: 1) balance off face pressure 2) penetrates the ground forming a ‘filter cake’ that reduces water ingress 3) mixing with the excavated spoil making it more fluid and easier to be transported away. Compressed air – an air-tight chamber with high pressure is located at the tunnelling face. No shield is required. WebbSlurry trenching is a method used to retard or redirect the flow of ground water by trenching around a construction area or contaminated site or to contain the groundwater at a contaminated site. The upgradient side of a slurry wall will divert groundwater flow around the site.
