The invention relates to the technical field of construction, in particular to an exceeding thousand tons of linear steel trussed beam floating pushing erecting construction method. The exceeding thousand tons of linear steel trussed beam floating pushing erecting construction method is characterized in that a steel trussed beam is assembled in advance in an offshore assembling site and then is continuously pushed through a hydraulic jack to enable a cantilever to be appropriate, then one end of the steel trussed beam is arranged on a bearing beam bracket supporting system which is formed by a barge, the barge drains water to lift and support the beam and continuously pushes the steel trussed beam to be advanced, the direction is adjusted in real time until the steel trussed beam is in place, water is injected into the barge, the support is converted, the top is mounded and the beam falls off, and the support is installed. Compared with the prior art, the exceeding thousand tons of linear steel trussed beam floating pushing erecting construction method has the advantages of being simple in equipment, convenient to operate, low in labor intensity, low in cost investment, high in construction efficiency and easy to popularize, not polluting river, not damaging the river bank, being short in construction navigation closing time, small in navigation interference, enabling main procedures such as steel trussed beam assembling and barge supporting to operate in a parallel mode and being beneficial to shortening of the working period.
