Long rail laying and welding construction technology under conditions of large temperature difference and strong wind and sand

Abstract

The invention discloses a long steel rail laying and welding construction process under the conditions of large temperature differences and strong sandstorms. The process comprises the following steps: carrying out track panel nail interlocking construction: nail interlocking construction is continuously carried out on a plurality of track panels used for construction by adopting track panel nailinterlocking lines, wherein the track panel comprises a plurality of sleepers and two tool rails arranged on the sleepers; 2. carrying out track panel lifting; 3. carrying out track panel laying construction; 4. carrying out long steel rail laying construction: the construction process comprises the two steps of displacing long steel rails and replacing and laying the tool rails in the laid trackpanels segment by segment by adopting the long steel rails; 5. carrying out plastic gas pressure welding on the two adjacent laid long steel rails by utilizing a dustproof incubator; and 6. carrying out stress dispersion and locking construction. The long steel rail laying and welding construction process provided by the invention is reasonable in design, simple in construction steps, convenient in realization, short in construction period and high in construction quality, and can be used for solving the problems of long construction period, low construction efficiency, poor construction effect and difficultly controlled welding quality and the like existing in the long steel rail laying construction under the conditions of large temperature differences and strong sandstorms.

Description

technical field [0001] The invention belongs to the technical field of rail laying construction, and in particular relates to a long rail laying and welding construction process under conditions of large temperature difference and strong wind and sand. Background technique [0002] During the construction of the new railway Xiwu Line, all the long rails required to be laid will be transported through the existing lines and stored in the rail storage base accordingly. During the actual construction, under the harsh climate conditions in Inner Mongolia, how to reasonably determine how to transport the long rails from the rail storage base to the track laying site, how to configure construction machinery and tools to optimize resources, and how to ensure the on-site welding quality of long rails under harsh weather conditions, Getting the lock temperature right is a construction challenge. Due to the harsh natural environment in Inner Mongolia, there are many natural disasters...
