Design and application of multiaxial jetgrouting impervious wall in the reinforcement project

Abstract

Abstract: Multiaxial jetgrouting impervious wall is a new vertical seepage prevention technique developed on the basis of multiheader paddling pile technique which has advantages of higher work efficiency, lower construction cost, complete wall body and good continuity, and is dam seepage prevention technique worthy to be generalized. The application of this technique in the reinforcement project of south segment of Hanjiang NorthSouth Dam in Chaozhou City, Guangdong Province was introduced, the selection process of design scheme and the construction of experimental section were analyzed. The result of the scheme was excellent.

Key words: multiaxial jet-grouting impervious wall, design scheme, experiment, application
