PURPOSE: To improve profitability and workability by devising the storage method of a block moving truck regarding the erection method of a bridge by a method of support type span-by-span precast block construction. CONSTITUTION: An erection girder 11 is forwarded completely, and the erection girder 11 is fixed. A bridge type crane 14 is moved up to a forward erection spot, and fastened. Only moving trucks 21, which are left as they are loaded on the erection girder 11 and can be stored at the rear of the erection girder 11, are left, and others are hung up by a moving-truck installation storage hoist 15 jointly provided to the bridge type crane 14, shifted to a storage place on a bridge girder 2, and stored temporarily. The block moving trucks 21 on the bridge girder 2 are returned successively to the erection girder, and loaded on the moving trucks 21 by the bridge type crane 14 from forward blocks 3a, and blocks 3 are erected in succession. |
