RCC DAM FOR FORMATION OF ATYPICAL CURVED SURFACE AND CONSTRUCTION METHOD OF THE SAME

摘要

The present invention relates to an RCC dam to construct an arch type wall surface by applying a combining socket to PC panels and a method to construct the same. According to an embodiment of the present invention, the RCC dam for formation of an atypical curved surface and the method to construct the same comprises: PC panels prepared as a precast concrete of a plate shape having a predefined thickness, and arranged adjacent to each other along the curved surface of the arch-shape dam design; an edge combining socket to pivotally couple the edges of the panels by engaging on an edge portion between the adjacent panels; a cross combining socket to couple the crossing part of four PC panels by engaging on a crossing part of adjacent panels; and an anchor assembly to adjust a panel angle connected by a hinge on at least two locations of rear surfaces of the panels. The anchor assembly comprises: a load arm of a predefined length around a panel; a turn buckle to adjust angle coupled to the load arm around the panel by a screw to adjust a standing angle of the panel; a load arm of a predefined length around an anchor with one end coupled by screw to the other end of the turn buckle; and an anchor connected to the other end of the load arm around the anchor, and laid under the concrete to construct the dam poured on a construction site.
