The invention relates to a construction method for erecting a segmental beam, which comprises the following steps of: 1, mounting a support on the top of a pier for mounting a span beam section, and adjusting the pre-deviation according to the design; 2, transporting the No.14 beam section to the tail part of the bridge girder erection machine by a beam transporting vehicle; thirdly, feeding beams at the tail and rotating the beams on a bridge girder erection machine; fourthly, the No.14 beam section is moved in the pier direction, and a space for coating epoxy resin is reserved; 5, hoisting the 13 # beam section to the 1 # beam section in sequence; sixthly, epoxy resin is smeared and closely attached, and the prestressing tendons are tensioned; and 7, the suspender is loosened, the beam falls to the designed position, and construction of the next span frame is carried out. According to the method, the problem of erection of the segmental beam without the under-beam beam transporting condition is solved by tr
