GENERAL 1.1. Basic Design Concept All of the bridges of this project will be selected from among the replacement of existing bridge, additional bridge, widening of the existing bridge, based on the location, the condition of bridge, the road alignment, vertical clearance for drainage. Detailed design is performed on the basis of especially rivers form, the ground conditions, construction methods and costs, safety, the result of environmental conditions and economic constraints. 1.2.

Substructure and Foundation 1. Widening Substructures of the same height as the bridge abutment height of the existing bridge. ・Pile position of widening abutment was planned to ensure the separation of 1.5m from the existing bridge abutment for the setting pile driver. (See figure “a”) ・Pile position of widening Pier was planned ensure the separation of 1.0m (See figure b) from the existing bridge superstructure for the setting pile driver. (See figure “b”) 2. Against the abutment ・Piling and substructure construction was planned from the construction base surface to the top of subbase course. 3. Against piers in the river ・ construction in the dry season. Implement the machine carried in by the approach path. ・Construction base surface is 50 cm higher than the height of the dry season of water. At this time, secure the flowing water by dewatering or pipes as needed.
