Design and Construction of the Support Structure of Deep Foundation Pit for a Cement Plant in SR Vietnam

Abstract:

Combined with a specific foreign-related project and based on the detailed report of the engineering geological investigation, this paper describes the application of the selected support structures of shotcrete-bolt and bored piles with high pressure rotary jet grouting waterproof curtain from aspects of scheme optimizing, design and construction, underground watertable lowering and result monitoring. Satisfactory achievements have been made in cost saving, shortening duration, facilitating construction and environmental protection etc. It demonstrates that two or multiple support systems can be used simultaneously in one foundation pit as support structure.
