The invention relates to a rail construction engineering van capable of changing rails. The rail construction engineering van comprises a main underframe (6) which is connected with inner rail wheels (14), a hopper (40) and auxiliary frames (1). The rail construction engineering van capable of changing rails is characterized in that a lifting assembly comprises lifting hydraulic cylinders (5) connected with the main underframe (6), and each pair of lifting hydraulic cylinders (5) are hinged to a supporting beam (12); an outer rail wheel assembly comprises tubular cross beams (4) connected to the main underframe (6), sliding cross beams (3) are arranged in the tubular cross beams (4), and the sliding cross beams (3) are hinged to telescopic oil cylinders (35); the sliding cross beams (3) are hinged to outer rail wheel carriers (24), and outer rail wheels (28) are hinged to the outer rail wheel carriers (24). Due to the fact that the technology is adopted, the rail construction engineering van capable of changing rails can be flexibly switched between a laid inner rail and a temporary rail, and concrete can be transported easily.
