<p>PURPOSE:To provide a laying method of power cable at an end of bridge through which a power cable can be deformed stably in a limited space. CONSTITUTION:A power cable 2, secured at an end of a bridge, is laid in curved shape between the end of bridge and a ground side fixed point while being gripped at a plurality of points in the intermediate curved part by means of cleats 3. The end part of bridge, the ground side fixed point, and the cleats at the intermediate part are linked through a four hinge arch constituted of four main pins 4a-4d and three main arms 5a-5c while furthermore the end of bridge, the ground side fixed point, and one pin at the intermediate part of the four hinge arch are linked through one pin and two auxiliary arms 7 thus supporting the power cable 2 while deforming regularly.</p> |
