REINFORCING APPARATUS AND METHOD OF INCLINED FACE USING ROCK BOLT AND LATTICE GIRDER DEVICE

摘要

A slope reinforcement apparatus using a rock bolt and a lattice girder device and a slope reinforcement method using the same are provided to reduce construction period by reinforcing a slope as the ground of the slope is punched, a rock bolt is installed, and pre-stress is applied at the same time. A slope reinforcement system comprises: a rock bolt(1) inserted into a mounting hole punched on a slope; and a lattice girder fixing device(30) which is installed to cover the slope and in which the tension direction end part of the rock bolt is mounted. The rock bolt comprises: a fixture composed of a tapered wedge body and a plurality of split pieces to cover the wedge body; a tension bar member coupled on the tension direction end part of the wedge body of the fixture; and a reaction bar member applying the supporting force to the split pieces. The lattice girder fixing device comprises: a girder lower plate having a through hole; a column portion having a vertical installation surface; a lattice girder(34) coupled on the vertical installation surface; and an upper bearing plate covering the upper side of the column portion.
