Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a construction girder and an erection method thereof, capable of installing a sleeper in an optional position.SOLUTION: A construction girder 1 is installed under tracks 50 and 50, and supports the tracks 50 and 50. The tracks 50 are constituted of a track bed 51 formed of ballast, the sleeper 52 arranged on the track bed 51 and a rail 53 arranged on the sleeper 52. The construction girder 1 comprises a box girder 11 being a box shape of opening an upper surface 11a and storing the ballast. The ballast stored in the box girder 11 forms at least a part of the track bed 51. 【課題】枕木を任意の位置に設置可能な工事桁、及び、その架設方法を提供する。【解決手段】工事桁１は、軌道５０、５０下に設置されて軌道５０、５０を支持する。軌道５０は、バラストにより形成される道床５１と、道床５１上に配置される枕木５２と、枕木５２上に配置されるレール５３と、により構成される。工事桁１は、上面１１ａが開口した箱形で、バラストを収容する箱桁１１を備える。箱桁１１内に収容されたバラストが、道床５１の少なくとも一部を形成する。【選択図】図７
