The invention discloses a horizontal rotating construction method for a steel truss beam bridge. The horizontal rotating construction method comprises the following steps: constructing a reinforced concrete pile foundation, a cushion cap, a slideway, a main pier and a cap beam in a rotating system by using a conventional construction technology, and mounting a rotating spherical hinge as a core part for rotating; mounting an upper rotating plate on the slideway for construction; constructing the main pier and the cap beam; mounting a permanent support saddle of the main pier; preparing safety measures before rotating; determining a weight scheme before rotating; preparing a jack; rechecking before rotating; performing rotating construction operation. Compared with other processes, the horizontal rotating construction method for the steel truss beam bridge, provided by the invention, has the advantages of high construction speed and low construction cost. The construction of a lower structure can be synchronously finished in the manufacturing process of a steel beam in a factory; the hoisting operation of symmetrical cantilevers can be performed when a spliced site is hardened to reach the traveling strength of cranes like crawler crane; main expenses are rental expenses of the cranes, so the cost is reduced.
