Abstract

PURPOSE:To protect the whole area of slope uniformly and strongly by a method in which L-shaped frames with many through holes are set in a lattice form, net is laid on the frames by loosening most of its central parts, and cement mortar, etc., is packed into the net. CONSTITUTION:A slope breaking preventing framework 1 is set on a given place of slope E by turning its supporting pieces 3 toward the mountain side, and frames 6 and 7 are vertically set in a mutually facing manner on both sides of the framework 1. The formwork 1, the frames 6, 7 are connected into a cross shape by connectors to fix the whole area of the slope E in a lattice form. A net 8 whose central part is mostly loosened is laid over all upsides of the formwork 1 and the frames 6, 7 and a filler 9 is sprayed onto the slope E, where the net 8 as a core material is hardened when the filler 9 hardens between the formwork 1 and the frames 6, 7. The slope can thus be exactly fortified by the simple method.
