Title:
FORMING METHOD FOR CONSOLIDATION GROUTING HOLE
Document Type and Number:
Japanese Patent JPH1113070
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a forming method for a consolidation grouting hole in which a temporary footing is not required, in which hole cutting work from a concrete placed surface is not necessary, and in which construction cost can be largely reduced. SOLUTION: A ground is excavated to a specified depth to form an excavated plate 20, this excavated plate 20 is used as a work place, and a hole 30 for consolidation grouting is formed in a foundation rock-bed exposed in the surface of an underground foundation rock-bed close to the surface. The excavated plate 20 is further excavated to a specified depth to form a new excavated plate 21, an excavation process is similarly performed on this new excavated plate 21, an excavated plate formation process and a hole boring process are then similarly repeated in order, and the consolidation grouting holes 30 are formed at all the necessary positions of foundation surfaces 2, 3 of a dam bank body.
