Abstract

Abstract:

The curtain grouting constructions in 3 different hydrogeological sections of the main tunnel in No. 3 inclined shaft work lot of Xiangshan tunnel are compared. Three different grouting schemes, i.e., fullface curtain grouting, surrounding curtain grouting and local curtain grouting, are discussed. The influence of different grouting schemes on the construction efficiency under different hydrogeological conditions is analyzed. Optimal grouting schemes are determined, the grouting technology and the construction organization technology are optimized, which achieves better controlled construction cost and reduced construction period.

Key words: curtain grouting, scheme optimization, rapid construction, wall for grouting, construction organization
