The invention belongs to the technical field of bridge engineering and relates to steel bridge construction, in particular to fabricated highway steel bridge rapid construction equipment. According to the technical scheme, a construction platform is formed by connecting and assembling two or more engineering buoyancy tanks through connecting ear plates; an outboard motor support for mounting an outboard motor is welded and fixed on the outer sides of the engineering buoyancy tanks; the outboard motor provides moving power for the construction platform; a crane, a power system, a hydraulic control station, a GPS and an anchoring system are arranged on the construction platform, wherein the crane is used for hanging a vibratory hammer and a tubular pile to carry out tubular pile construction; the power system provides power for the vibratory hammer; the hydraulic control station is used for controlling the vibratory hammer to carry out tubular pile operation; and the GPS is used for tubular pile positioning. With adoption of the fabricated highway steel bridge rapid construction equipment, the space between two tubular pile is free of limitation to fully play the bearing capacity of a steel bridge; the fabricated highway steel bridge rapid construction equipment is suitable for highway transportation and convenient to transport and store, can carry out construction in unnavigable rivers and lakes, and solves the problem that a large pile driving barge cannot reach a piling site; and concurrent construction of a pile foundation and a bridge span can be carried out, so that the construction efficiency is effectively improved.
