Abstract
PURPOSE: To prevent a crack from occurring by decreasing a temperature difference between interior and surface concrete by placing concrete after installing precast concrete boards on the surface of a mass concrete structure and fabricating a frame work. CONSTITUTION: A jig 8 is mounted on previously placed concrete 4, a precast concrete board (PC board) 1 is mounted on the slope of the jig 8, and fastened temporarily by the PC board 1 below and a plate 6. The PC board 1 is installed on the upstream and downstream sides of a levee body inside a steel material 2 in place of a form, and supported strongly by embedded anchors 3 and the steel material 2. To integrate with the levee body concrete 4, dowel bars 5 are attached to the reverse of the PC board 1, all adjacent PC boards 1 are connected, and a sealing compound 7 is attached to each joint, and concrete is placed to form one lift of concrete, thereby preventing micro cracks from growing.
