摘要： PURPOSE:To make it possible to execute work even in a steep valley where it is difficult to secure a yard or a working space by securing dispersed working spaces and overhanging blocks, using temporary beams on a bridge leg and forming a bridge. CONSTITUTION:Precast blocks B are lifted up from a yard under a central bridge leg P2 and are overhung so that a bridge may be formed. A temporary beam E is pulled out from a yard of a bridge base A1. The temporary beam E is supported with a bridge or the like overhanging from the bridge base A1 and the central bridge leg P2. The precast blocks stored in the yard of the bridge base A1 are moved horizontally one after another, using the temporary beam E. Then, the overhanging of the bride is closed by connecting the precast blocks one after another. Then, the temporary beam E is moved between the central bridge leg P2 and a bridge base A2. The precast blocks stored in the bridge base A2 yard are connected with each other in the same procedure, thereby completing the bridge.

摘要： PURPOSE:To have excellent execution efficiency and safety and to minimize the traffic control of an aerial wiring section by performing the title election simultaneously in the direction of the width. CONSTITUTION:A pair of pin keepers 8a and 8b are placed on an arch foundation provided to a specific position in advance, one end of an arch B is connected to the pin keeper 8a nearer thereto of both pin keepers 8a and 8b through a pin and, at the same time, the each B is reversely built up. The front end of the arch B built up is reached to the forward pin keeper 8b of both pin keepers 8a and 8b by a crawler crane A while revolving with the pin nearer to the arch B as the center and is connected to the pin keeper 8b through a pin.

摘要： PURPOSE:To dispense with reinforcement of a cantilever part by minimizing turning of a load on a supporting pedestal at moving a movable timbering, and loading no load of the movable timbering on the bridge body of the cantilever part. CONSTITUTION:A front end supporting pedestal 4 to journal a movable timbering is previously placed on the capital part of a bridge pier movably through a slide base, the front end supporting pedestal 4 is moved forward on the slide base, and a placing space to draw an intermediate supporting pedestal 5 near is insured on the capital part. The intermediate supporting pedestal 5 is moved forward as far as the placing space. The load of the movable timbering is turned to the intermediate supporting pedestal, and the load on the front supporting pedestal is eliminated. The front end supporting pedestal 4 is transferred on the next capital part and fitted to it. The movable timbering is moved forward, and the extreme end 7 of a launching beam is reached to the other capital part. A concrete bridge body is constructed by holding a formwork with the movable timbering.

摘要： PURPOSE:To raise the efficiency of operation by preventing the deviation of the axis of concrete arches facing each other, make regulation to the stress of concrete arches easier, simplify the construction work of concrete arch, and shorten the period of construction. CONSTITUTION:On near the top of a concrete arch bridge 10, the tip A of one concrete arch 10a is constructed by concrete C, and after the concrete C hardens, a small-thick jack 11 is attached to the side end of the tip A. Concrete C is then placed on the tip B of right-handed concrete arch 10b, and after the concrete C hardens, the jack 11 is operated to form an aperture S between both the concrete arches 10a and 10b to adjust the stress and deflection of the concrete arch 10. A cement mortar or concrete C is placed to the sperture S to complete the close jointing work of the concrete arches.
