Steel trestle track construction method

The invention relates to the technical field of building construction and particularly relates to a steel trestle track construction method. The method comprises steel trestle track design: most of columns of the steel trestles are erected first-layer concrete inner supports, and the trestle columns and inner support latticed columns must be designed consistently so that the trestles can still be used after the inner supports are blast and counter force of the trestles can be transmitted to raft foundations; steel trestle mechanical analysis: analysis is performed through software, simplification calculation analysis of largest inter-node distance in steel girder actual size is performed, vestibule structures are calculated, and stability checking is performed through the software, and the steel structure design code stability design requirement is met when the stability checking maximum stress of all members under the action of structure self-weight and car loads is smaller than 1.0; steel trestle installation. Compared with the prior art, the method has the advantages that the problem of the construction site is solved, the members are transported horizontally, and accordingly, the investment is low, the effect can be produced rapidly, and the construction period is shortened.
