Method of construction of cable trough bridge and laying member of cable trough bridge

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a cable trough bridge that does not require manual excavation of an abutment foundation part and an under-bracing block part, treats easily surplus excavated soil, is extremely lighter in weight, and can transport a cable trough to a top of a slope face serving as a place for the trough to be laid on and lay the cable trough at an extremely low cost, and a laid member for a cable trough bridge.SOLUTION: In the construction method for a cable trough bridge, a pair of support piles are driven into a cable trough bridge construction place at predetermined intervals between the support piles, a holding beetle having a pair of ring-shaped support pile fitting links on both ends thereof is installed between the support piles, from upper end sides of the driven support piles, by inserting the support pile fitting links through the support piles, cable trough fasteners, which are extensible/contractable and adjustable in a width direction of the cable trough bridge, are installed on the holding beetles, and a cable trough is laid between the installed cable trough fasteners.
