【Abstract】 This article discusses the construction technology for large scale open caissons, including mixing of thixotropic slurry, pipe laying, conveying and replacing of slurry. The working caisson for the pipe jacking engineering of Ji’nan Queshan Reservoir is taken as an example to show the construction procedure and method.The application effect of thixotropic slurry is analyzed from two aspects—maintaining of the soil wall stability and reducing of the friction resistance between caisson and soil.更多还原
