■ Excavation method using Anchor lock machine

The scaffoldless drilling machine (Series of ARM) and anchors installed at the top of the slope behind the estimated collapse line are securely fixed by wire ropes, and drilling is performed at any position on the slope

Drilling work can be performed safely and efficiently without scaffolding on high slopes, steep slopes, dam construction sites.

This eliminates the need to assemble and remove temporary scaffolding, greatly shortening the construction period and saving labor.

ARM07-2, which started full-scale operation in 2016, is equipped with a spanner device, an eight-legged synchronization mechanism, and a wheel-removal prevention device, all of which allow it to move freely on high-altitude slopes. With this equipment, we can now proceed without damaging the frame of the slope. The boom of ARM07-2 can be moved up and down, left and right, and the angle can be adjusted to allow drilling in up to three locations at the same position. In addition, ARM07-2 is compatible with the grout rotary drilling method, which was invented by our company and enables single-pipe drilling even in unstable strata.
