Title:
A SUBSTANCE, WHICH CAN BE CURED IN THE EARTH, FOR PERMANENT FASTENING AN EARTH ANCHOR OR GROUND ANCHOR AND A METHOD FOR INSERTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/194893
Kind Code:
A3
Abstract:
The invention relates to a substance (5), which can be cured in the earth (2), for permanent fastening of an earth anchor and to a method for inserting the substance (5). The water insoluble substance (5) is injected in liquid form into the drilled hole (1) at high pressure by means of a tubular feed element (3). Said substance (5) has a greater viscosity and density than water, such that the substance (5) independently penetrates the surrounding earth (2) and displaces any liquid present there. In addition, the distribution, in particular the radial penetration depth into the earth (2) in relation to a drilled hole longitudinal axis, can be determined and adjusted via the pressure at which the liquid substance (5) is fed, or the movement of the feed element (3) in the direction of the arrow (12) in the drilled hole (1).
