Abstract

Abstract: Consolidation grouting is very important for foundation treatment of hydraulic structures. The author mainly introduces the construction technology and related construction parameters of consolida-tion grouting through guiding pipe for dam foundation of hydropower station. It is proved by practice that the technology is feasible, economical and reasonable, and the grouting quality meets the requirements of design and specifications.

Key words: consolidation grouting, guiding pipe in dam foundation, construction technology
