Abstract

The invention discloses a ballastless track construction method and a ballastless track construction device for a continuous beam-arch combined bridge, the bridge is the continuous beam-arch combinedbridge, and the method comprises the following steps: acquiring bridge linear change data; obtaining a ballastless track linear geometric model according to the bridge linear change data; comparing the ballastless track linear geometric model with a ballastless track design model to obtain a preset adjustment value of a ballastless track; and laying the ballastless track according to the preset adjustment value so as to adjust the ballastless track to form to the ballastless track. The linear deformation deviation of the ballastless track is prevented from being too large in the construction process, the geometrical shape of the ballastless track after being formed is improved, the linear quality of the ballastless track is guaranteed, and then it is guaranteed that the linear shape valueof the ballastless track meets the design and standard inspection requirements.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a ballastless track construction method and device for a continuous beam-arch composite bridge. Background technique [0002] Ballastless track is a common type of high-speed railway track structure today. It has the advantages of stable structure, good track geometry, and small maintenance. However, due to the limitation of the adjustment range of its fasteners, once the construction of ballastless track is completed, the rail linearity The adjustment range is very small. Once it exceeds the standard, it may cause problems such as peeling and rework. Therefore, the linearity of the track is extremely required during its construction, especially when it is involved in the construction of super-large-span continuous beam-arch composite bridges. The linear deformation of the ballastless track is relatively complicated. If the construction is rash, the linear deviation of...
