UNDERGROUND CONTINUOUS WALL CONSTRUCTION WORK

摘要

PURPOSE:To enhance the effect of water stopping by using an expanded concrete for the joints of underground continuous walls. CONSTITUTION:Reinforcing bars are set in a trench excavated in the ground, and concrete is placed in a repeating manner to form sideward walls 2 connected. In this case, an expansive concrete 1' to be easily expanded and hardened as such during hardening period is used. The aperture in the joints of wall panels can thus be greatly reduced and the water-stopping effect of the walls can be improved to a great extent.
