Application of Foamed Concrete in Karst Rock Cavity at the Riverside Pile Foundation
The karst geological conditions of a shallowly buried pile foundation at the riverside are complicated,and the karst rock cavities are well developed.Before the pile installation,a detailed geological and geotechnical investigations are performed,and the technical research of underwater lightweight foamed concrete is also carried out.The lightweight foamed concrete is produced by the fully mixing foam agent and the cement mortar.Finally,an engineering drill is used to set up the pilot hole to the bottom of the karst rock cavity.The foamed concrete pouring pipe is buried and the underwater lightweight foamed concrete is poured through the this buried pipe.
