Abstract
PURPOSE:To transfer and install the trestle girder and crane most efficiently by providing a structure consisting of plural lower-level pillars and the trestle grider at a dam construction site and repeating concrete placing work using the crane on the girder. CONSTITUTION:The lower-level pillar 11 is erected on pillar foundation 5A-5J at a section corresponding to the dam construction site and the trestle girder 9 is installed across the upper ends of lower-level pillar 5. This erection and bridging work are repeated, completing the lower-level structure, on which the jib cranes 10, 12 are assembled. This lower-level structure will be provided at two positions, backward and forward. On the backward structure, the jib crane 17 is mounted and then concrete for a lower dam body is placed. After this process, an upper-level pillar 23 is erected on the lower-level pillar 11 and the trestle girder 9 is lifted by means of a hydraulic cylinder along the upper-level pillar 23, thus forming a structure. On thus structure, the jib crane is mounted. By this sequence, a dam is constructed.
