CONSTRUCTION METHOD OF CONCRETE BRIDGE AND MOVING WORKING DEVICE USED BY METHOD OF CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a construction method of a concrete bridge which can contribute to the reduction of a construction period while eliminating a reduction in connection strength of a reinforcement in the axial direction between each blocks of the reinforcement structure of adjacent blocks which is caused by the displacement of the position of the reinforcement in the axial direction. SOLUTION: The construction method of the concrete bridge 7 is by reinforcement preceding assembling that the assembling of the reinforcement structure 55 for the next block 43 is performed ahead of the completion of the construction of one block 39. The reinforcement 61 in the axial direction for the next block 43 is directly connected to the end 59 for connection of the reinforcement in the axial direction of one block 39 under construction, and the reinforcement in the cross-sectional direction is attached to the reinforcement 61 in the axial direction. Because of this, the reinforcement structure 55 for the next block 43 is assembled in the position of the next block 43. COPYRIGHT: (C)2011,JPO&INPIT
