The invention discloses an integrated processing method for designing, manufacturing and constructing track skeletons of a medium and low speed magnetic aviation track. The method includes the steps that the type, the number and the girder span length of bridges needing to be constructed along a line are determined according to design parameters of the line and foundations blow the line; according to the girder span length of the bridges along the line, the type and the number of track skeletons and telescopic joints along the line are determined, and track skeleton arrangement and design data are formed; according to the track skeleton arrangement and design data, machining data of each truss of track skeletons and the telescopic joints are formed; according to the track skeleton arrangement and design data, theoretical space three-dimensional design coordinate data of track skeleton measurement points are formed with the mileage as an index and are used for precise adjustment during track skeleton on-site installation and construction; and after precise adjustment of the track skeletons and pouring of a lower track supporting table are completed, actual three-dimensional coordinates of the track skeleton measurement points are acquired and compared with the track skeleton arrangement and design data, and track skeleton space position deviation data are formed. By means of the method, parameter data in designing, manufacturing, constructing, maintaining and other links of the track skeletons can be shared and optimized, and the track skeleton precision and stability are improved.
