INSTALLING METHOD AND APPARATUS FOR CATWALK ROPES IN SUSPENSION BRIDGE BY CONTROLING TENSION FORCE OF A CATWALK ROPE

摘要

The present invention relates to a technology for installing a catwalk rope on a suspension bridge crossing a ship's route, and more particularly, when installing a catwalk rope on a suspension bridge using a holding system using pullers and tensioners at both ends of a holding cable. In order to prevent the catwalk rope from sagging excessively and obstruct the ship's course, the ship can smoothly pass under the suspension bridge along the original course, but the puller 101 and the tensioner 102 are connected to the preceding hole cable, respectively. By controlling the operation according to the size of the tension (T1, T2) of the 105a and the trailing hauling cable 105b, by controlling the tension of the catwork rope only by adjusting the tension of the catwork rope, The present invention relates to a catwalk rope placing method and a placing device in a suspension bridge configured to prevent excessive tension on the rope.
