ROCK BOLT CONNECTED WITH STEEL STRAND AND METHOD FOR STABILIZING A ROCK SLOPE AND FORMING GRASS GROWING LAYER ON THE ROCK SLOPE USING THE SAME

摘要

A rock bolt connected with a strand is provided to be installed closely to a rock slope or a structure without having a hole formed on a rock slope perpendicularly, and a method for stabilizing a rock slope and forming a vegetation layer using a rock bolt connected with a strand is provided to stabilize a rock slope and to form a vegetation layer by using a rock bolt connected with a strand and a fiber form having a pore, to form a vegetation layer for possibly vegetating at an early stage, to form a vegetation layer without being lost or damaged by external force such as rainfall, and to construct with low expenses. A rock bolt connected with a strand comprises a reinforcing bar(100) fixed to a hole(20) formed in a rock slope(10), a strand(200) formed to make one side exposed to the outside of the hole and the other side connected with the reinforcing bar, a connector(300) connecting the reinforcing bar and the strand, and a head(400) fastened to the exposed part of the strand exposed to the outside of the hole. A method for stabilizing a rock slope and forming a vegetation layer using a rock bolt connected with a strand comprises the steps of: forming a hole in a rock slope; fixing a rock bolt composed of a reinforcing bar, a strand connected with the reinforcing bar and a connector connecting the reinforcing bar and the strand into the hole to make one side of the strand exposed to the outside of the hole; paving a fiber form provided with an inside space to be filled with a vegetation material to the rock slope; penetrating the exposed part of the strand exposed to the outside of the hole through the fiber form, and fastening a head to the exposed part of the strand; and injecting a vegetation material to the inside space of the fiber form using an injection device having a pipe-shaped injector.
