<P>PROBLEM TO BE SOLVED: To minimize diving operations, to improve work efficiency, to shorten a construction period and to reduce a construction cost, in the case of constructing or demolishing a pile type landing bridge at a location where water is deep such as a dam lake. <P>SOLUTION: A landing bridge construction method includes: a basic assembly step of basically assembling a truss member comprising a plurality of pipes extended in parallel with each other and a connection member for connecting the pipes adjacent to each other in an oblique direction and a perpendicular direction to a pipe length direction; a truss member arranging step of suspending the truss member such that the length direction of the pipes is the vertical direction at a position to extend a landing bridge a prescribed distance away from a landing bridge completed part, and arranging it at a prescribed height position floated upwards from a ground surface; a support pile installation step of inserting a tubular support pile into the pipe of the truss member arranged at the prescribed height position and installing it to the ground surface; a pipe fixing step of fixing the pipe of the truss member to the constructed support pile; and a connecting step of connecting the pile supporting the landing bridge completed part and the pipe fixed to the support pile by a beam. <P>COPYRIGHT: (C)2012,JPO&INPIT |
