CONSTRUCTION METHODS FOR PREVENTING LAND EROSION AND IMPROVING STREAMS, OR FOR REVETMENTS, AND CONSTRUCTION METHODS FOR PREVENTING MOUNTAIN LANDSLIDES

摘要

Erosion and collapse of torrents and rivers are prevented by anchoring timber, stone or the like with a longitudinal rope (steel wire rope) (1). Collapse of hillside is prevented by placing moored objects such as timber and stone (3) anchored by the longitudinal rope (1) at those locations on ground near locations of hillside erosion and collapse, in a substantially stepped or parallel arrangement.
