[0003] In this kind of slope or slope construction, when drilling is required for the ground, work using a ground scaffold (slip scaffold) or a single pipe or H-shaped steel on the slope is required. A gantry was installed, and a punching device was installed on the work gantry to perform a piercing work.

[0004]

However, when a work platform is installed on a slope to perform drilling work, however, it is necessary to install a drilling device on the work platform, or to rearrange or move the machine afterwards. First, it is required that the boom of a truck crane, a crawler crane, or the like be within a reachable range. In other words, slope stabilization work and slope work will be done in relatively flat areas such as mountainous areas and places where it is difficult to secure yards. In the middle, a part of the road is occupied by the heavy equipment, and there is a problem that a traffic obstacle occurs. In addition, when the slope height is large, a large-sized heavy machine having a large capacity is required, so that a problem such as an increase in construction cost accompanying the construction of the lock bolt or the ground anchor has occurred.
