土または岩の材料内に孔を掘削し、かつアンカーを形成するための方法および装置
Document Type and Number:
Japanese Patent JP2007530824
Kind Code:
A
Abstract:
A method and device for boring a hole in soil or rock material and for forming an anchoring are disclosed. A borehole is formed by inserting a drill bit, and tensioning elements coupled to the drill bit are introduced into the borehole. After completion, the boring rods are detached from the drill bit and removed. The boring rods are provided with a hollow space in its longitudinal direction to introduce a hardenable fluid into the borehole. Anchoring or fixing elements for anchoring on the borehole's inner wall are provided on the drill bit at the end opposite the drilling surface and/or on the tensioning elements. The tensioning elements are subjected to a turning or twisting whereby shortening their effective length for tensioning or centering so that a centering and an optionally temporary tensioning of the tensioning elements can be effected before the hardenable material completely hardens.
