Abstract: The doubleblock ballastless track is a new type of track with high requirements on trak geometry form and position and track bed board concrete. The problems occurred to the construction are presented with the fine turning of the track, grouting of the track bed board and construction organization of CRTS Ⅰ type doubleblock ballastless track of Xiamao tunnel on XiangtangPutian railway. The conclusions of the paper can provide reference for similar projects in the future.
Key words: Xiamao tunnel, ballastless track, fine turning, track bed board, concrete
