APPLICATION PROCESS FOR CONTINUOUS WALL OF UNDER GROUND REINFORCED CONCRETE

摘要

PURPOSE:To make application process effective by a method in which a form is incorporated into the connecting position to the tunnel of the continuous wall of the reinforced concrete of an under ground structure, and the form is filled with the muddy water in which the beads of specified specific gravity are dispersed, and then a void-filling wall is placed and is easily removed when the tunnel is bored. CONSTITUTION:The form 4 provided with bottom plate which has the injection hole of cement milk is incorporated into the connecting position to the tunnel under ground in bar-arranging process of the continuous wall 12 made of the reinforced concrete constructed on the foundation which is bored with the injection of stabilizing liquid. Next while the form 4 is filled with the muddy water in which the beads with the specific gravity of 1.0-1.2 is dispersed, concrete 11 is placed. Further cement milk is poured into the form 4, and the muddy water is replaced by said material, and then void-filling concrete wall 13 is placed. The bottom plate of the form 4 is removed and the partition wall 15A for a shield machine 16 is provided. Consequently, the mirrow-cutting of the wall may be made unnecessary.
