Title:
METHOD FOR CONSTRUCTING FOUNDATION OF BUILDING AND THE LIKE USING AGGREGATE
Document Type and Number:
Japanese Patent JP2530980
Kind Code:
B2
Abstract:
PURPOSE: To reduce the cost of differential settlement correcting work by repeating the work of placing aggregate on a foundation and the ground and crushing it with a power hammer piece and driving it in, thereby forming an aggregate post.
CONSTITUTION: Should differential settlement of an existing foundation 1 occur or the possibility of sinking be anticipated, holes 5 are bored in the foundation 1 by a desired number and rubble stones 3 located beneath the foundation are removed. Next, aggregate 6 easy to crush, such as concrete rubble or tile is put in a hollow portion 7 and is hit and crushed using the hitting piece 10 of a power hammer 8. The above work is repeated to driven the aggregate 6 deep into the ground while an aggregate post is formed as necessary. After the aggregate post has begun to work sufficiently as a pile, concrete is poured from the holes 5 and integrated with the rubble stones and the foundation, etc. A tough aggregate post can thus be formed in accordance with the state of the ground and be prevented from sinking over a long period of time and be constructed at low cost while its vibration resisting force can be enhanced.
