CONSTRUCTION OF GOKAYAMA DAM BY THE CRUISING RCD CONSTRUCTION METHOD
RCD (Roller Compacted Dam-Concrete) construction method was developed as a rationalizing dam concrete placing method and has been used to speed up the construction works of concrete gravity dams.The cruising RCD construction method adopted to construct Gokayama Dam has been developed to aim for even more rationalizing dam concrete placing,and which improves construction work efficiency by advancing the placing procedure of the internal RCD,so it enables the continuous placement of dam concrete and enables placement of concrete more speedily.In Gokayama Dam,the slumping concrete is placed in the outer concrete and RCD is place in the inner concrete.Originally,the RCD is not placed unless the placement of slumping concrete is finished in one lift.The cruising RCD construction method is that the placement of RCD starts from one side of the dam site,while the slumping concrete is placed at the other side of the dam site.in that case,the RCD is placed at the next lift.Simultaneously,the RCD and slumping concrete are placed at different two lifts.The placement of RCD antecedent to that of the slumping concrete enables this execution,unlike the conventional RCD construction method in which the slumping concrete is placed antecedent to that of RCD.
