FIELD: construction.SUBSTANCE: device for installation of wire anchors on slopes and in ravines includes a guide rod, a wire anchor with conical tips. The guide rod is placed onto the wire anchor, where a movable lower stop is fixed. A jumper bit is installed upstream the lower stop along the rod, and the bit is put in reciprocal motion mechanically with the help of a sliding handle. Upstream the jumper bit there is a return spring with a movable upper stop provided during driving on the rod. After driving, as the guide rod is withdrawn, the place of installation of the return spring changes, and it is installed on the guide rid under the jumper bit.EFFECT: increased efficiency and reliability of installation of wire anchors on slopes and in ravines, reduced labour intensiveness and material intensity.4 cl, 4 dwg |
