The invention discloses a construction method for pipe gallery construction through a formwork trolley, and belongs to the field of pipe gallery construction. The construction method aims to improve the forming quality of concrete and improve the construction efficiency. The construction method comprises the following sequentially-conducted steps that 1, a horizontal hydraulic jack is retracted, so that a lateral formwork rotates slightly with the hinged position of the lateral formwork and a top formwork as the axis so as to be disengaged from a concrete pouring layer; and 2, the top formworkis lowered, so that the top formwork is disengaged from the concrete pouring layer until the formwork trolley for pipe gallery construction can travel freely. According to the construction method, firstly, the top formwork and the lateral formwork are hinged into a whole, so that the integrality and the strength and rigidity properties of the formwork trolley are improved, formwork expansion is avoided, and splicing seams are less; secondly, the self weight of the trolley is low relatively, maneuverability and flexibility are good, so that the efficiency of jack supporting and formwork disengaging is improved, and the moving speed is increased; thirdly, the horizontal hydraulic jack is downsized and miniaturized, materials used by the formworks and a truss are subjected to optimization design, thus waste is avoided, and the manufacturing cost is lowered significantly; and fourthly, through a formwork disengaging mode, stress is safer and more reasonable, and formwork disengaging is quicker and more reliable.
