Earth-Anchor Apparatus for Slope-Reinforcement-Construction

摘要

According to the present invention in, the expansion anchor projecting from the anchor structure inserted into the hole and interfere with perforations, to infiltrate pressing in the expansion anchor by a tensile force to the perforations carrying out the fixing of the also as anchor structure itself ground, the earth anchor the earth anchor structure which maximizes the ground fixing power is provided.; The subject innovation is the steel wire 10 is provided an anchor cap (16) on its front end an anchor body 14 which is engaged by the tapered cone (12) is provided, wherein the anchor cap 16 and the anchor body 10 for this purpose that with installed expansion anchor (20) is radially protruded into the elastic force of the spring 18 between, the rear portion of the expansion anchor (20) is formed with a locking projection 22, the anchor body 14 has been through this the locking projection 22 and the engaging locking groove 24. the locking member 26 is formed is formed by releasing the interference of the engaging groove 24 and the locking projection 22 in this operation wire that allows the radial protrusion ( 28) of said extension such that the press penetration into tension with the perforations 100 of which is connected the other hand, the spring 18, the hole 100 protrudes the expansion anchor (20 expansion is in) by an operating wire (28) the rear of the anchor (20), converting the tapered surface 30, which converts the tension of said operating wire (28) laterally are formed And further characterized in that the end portion, and cuff 34 having a conversion tapered surface 32, which contacts the conversion tapered surface 30 of the locker 26 is formed.
