Ground transportation track installation method

Abstract

The invention belongs to the technical field of ground track mounting construction, and discloses a ground transportation track mounting method. The ground transportation track mounting method comprises the steps that 1, tracks and base steel plates are assembled in a segmented mode, specifically, the base steel plates are grouped and sequentially laid on the flat ground, the ends of the adjacentbase steel plates in the same group are arrayed and laid in a closely-attached mode, surveying and setting-out are conducted on all the groups of base steel plates, the track mounting positions are marked on all the groups of base steel plates, in each group, the tracks are hoisted on the base steel plates to be aligned with the marked track mounting positions, then the tracks are fixed to the base steel plates, heat deformation of the base steel plates in the machining process is corrected through the rigidity of the tracks while fixing is conducted, thus the track steel plates are closely attached to the bottom faces of the tracks, and after completion, assembled segments of the tracks and the base steel plates are formed in all the groups; 2, hoisting and butt joint are conducted in a segmented mode; and 3, grouting fixing is conducted. According to the ground transportation track mounting method, the track mounting sequence is changed, deformation correction of the base steel plates is conducted through the rigidity of the tracks, and thus the mounting error caused by deformation of the base steel plates can be reduced.

Description

technical field [0001] The invention belongs to the technical field of ground rail installation and construction, and in particular relates to a method for installing a ground transportation rail. Background technique [0002] In modern industrial production workshops, ground rail transport vehicles are often used to transport internal items (including materials and finished products, etc.). Therefore, when the factory is constructed, ground transport track facilities for rail transport vehicles are designed. [0003] The installation of the ground transportation track is generally laid on the concrete strip track foundation. During construction, the track foundation is first poured with concrete, and then the base plate bearing the load of the track and its upper side is laid on the track foundation, and the foundation bolts are passed Fix the base steel plate and the track foundation together, and then perform secondary grouting between the base steel plate and the track f...

AI Technical Summary

Problems solved by technology

[0005] However, due to the flame cutting process of the base steel plate in the processing process, that is, thermal processing such as edge cutting or hole cutting with flames, the base steel plate is deformed due to thermal influence; , before the track is installed, the base steel plate forms a solid rigid whole with the ground track foundation through secondary grouting of concrete. The deformation of the base steel plate is fixed by the concrete track foundation, and the track body is also a rigid object. When installing the track, it is found that the bottom of the track and the base steel plate When the contact fit is not tight, it is impossible to correct it, resulting in the failure to meet the quality requirements of track installation
