CONSTRUCTION METHOD OF APPROACH SECTION OF VIADUCT, STRUCTURE BASED ON CONSTRUCTION METHOD OF APPROACH SECTION, AND STRUCTURAL OBJECT HAVING THE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a construction method of an approach section by which the approach section of a viaduct can be constructed without substantially regulating the traffic of an existing road, but only with short-time regulation during night time etc., if any, and to provide a structure based on the construction method of the approach section, and a structural object having the structure.;SOLUTION: The approach section 5 comprises a precedent construction part 9 of the first section which is constructed to be narrower than an intended width of the approach section 5, and a rapid construction part 11 of the second section which is constructed adjacent to a side face of the precedent construction part 9. The rapid construction part 11 is arranged so that the axial direction of a tube-like rectangular block 19 for the rapid part may be oriented in a vertical direction. The side face of the rectangular block 19 for the rapid part is placed in a manner of abutting on the side face of a tube-like rectangular block 13 for the precedent part on the precedent construction part 9.;COPYRIGHT: (C)2007,JPO&INPIT
