CONSTRUCTION METHOD OF LANDING BRIDGE FOR TUNNEL CONSTRUCTION, AND LANDING BRIDGE FOR TUNNEL CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a construction method or the like of a landing bridge for tunnel construction, capable of easily constructing a suitable landing bridge for tunnel construction corresponding to the tunnel construction.;SOLUTION: By selecting a floor part unit member 11-n, a main girder unit member 13-n, a bracket 25 and a cylinder 27, etc., corresponding to the tunnel construction, transporting them to a tunnel construction site, and assembling the unit members at the tunnel construction site, a floor part 11, a main girder 13 and a flip-up mechanism 35 for flipping up a get-on base 15 of a landing bridge 1 for the tunnel construction are configured, and the landing bridge 1 for the tunnel construction is constructed. By selecting kinds of the floor part unit member 11-n, the main girder unit member 13-n and a flip-up mechanism unit member by the bracket 25 and the cylinder 27, the width, length, loadable weight and flip-up height of the get-on base 15 of the landing bridge 1 for the tunnel construction can be changed according to the tunnel construction.;COPYRIGHT: (C)2013,JPO&INPIT
