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

Embodiment 1

[0022] Embodiment one: if figure 1 As shown, the process flow of the ground transportation track installation method includes the following steps:

[0023] Step 1: Assemble the track and the base plate in sections. The length of the single track used is 12m, and the length of each base plate is 2m. The width of the base plate is selected according to the actual design requirements. The six base steel plates are grouped into one group, and the six base steel plates of the same group are laid on the flat ground to form a section of 12m in length, and the measurement is made on the six base steel plates in each group that are 12m long. Mark the installation position of the track by setting out the line. When measuring the line, you can choose to reserve a position of 0.5-1.0 meters long at one end of the 12m length, and hang the track on each group of base steel plates to align with the marked track installation position, because in the measurement Reserve a 0.5-1.0 meter long p...

Embodiment 2

[0026] Embodiment 2: The process flow of the ground transportation track installation method includes the following steps:

[0027] Step 1: Assemble the track and the base steel plate in sections. The length of the single track used is 12m, and the length of each base steel plate is 1.2m*2m. Follow the laying method of the base steel plate on the track foundation, and carry out the five base steel plates as a group. In groups, the five base steel plates of the same group are laid out on the flat ground with a width of 1.2m in order to form a section of 10m long, and the set-out marks are measured on the five base steel plates laid out in each group to form a 10m long track installation Position, hoist the track on each group of base steel plates and align with the marked track installation position, each end of the track extends 1m from the edge of the 10m long base steel plate spread; then use a rail clamp to fix the track on the base steel plate ;The rail pressure device inc...

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...
