Roadbed structure of straddle type monorail low line, and construction method thereof

The invention provides a roadbed structure of a straddle type monorail low line, and a construction method of the roadbed structure. The roadbed structure comprises a plurality of piers and a plurality of supporting pieces which are used for supporting a track beam of a straddle type monorail, the piers are arranged at intervals in the extending direction of the track beam, and the piers are supported at the end of the track beam and fixedly connected with the bottom of the track beam; a supporting piece is arranged between every two adjacent piers of the same track beam, the supporting piecesare supported at the bottom of the track beam, and the track beam can be separated from supporting of the supporting pieces. The piers and the supporting piece of the roadbed structure bear loads ofthe track beam and a train on the track beam at the same time and transmit the loads to the stratum, meanwhile, the supporting pieces can control deformation of the track beam, and the structure is stable and reliable.
