Document Type and Number:
Japanese Patent JP2002144295
Kind Code:
A
Abstract:
To easily form a proper hole for surely and firmly burying an anchor or the like and to remarkably improve the working efficiency in a boring method and a boring device for boring a composite solidified matter such as concrete obtained by mixing plural materials of various strength and solidifying the same.
A nozzle is moved to a predetermined boring position on a surface of the composite solidified matter and located in opposition thereto, a cavitation jet is injected to form a boring end on the surface, and then the cavitation jet is continuously injected while moving the nozzle along a predetermined locus by a rotary moving device or the like to extend the bore from the boring end, whereby the desired bore can be efficiently formed.
