CONSTRUCTION OF CONCRETE CUT-OFF WALL FOR DAM SLOPE

摘要

PURPOSE:To continuously and economically construct a concrete facing on the slope of a dam as well as greatly shorten the period of the construction by running vertically a paving machine on the slope of the dam. CONSTITUTION:An uncured dry-consistency fiber concrete is delivered onto the top 1 of a dam by a dump truck 2 and a facing concrete is continuously constructed in a belt-like form by means of a paving machine running vertically on the slope. The paving machine consists of a finisher 3 to be dragged by a main winch porter and a vibrating roller 4. The face of foundation is compacted by a dumper vehicle 6 while delivering concrete. The vibrating roller 4' for finishing and compaction is dragged for final compaction and a joint cutter is run before the concrete is hardened following the compaction.
