Continuous beam type rail construction method
The invention discloses a continuous beam type rail construction method, and relates to the technical field of rail traffic construction. The method specifically comprises the following steps: when a rail beam is prefabricated, connecting components are embedded in the two ends of the rail beam; when a pier column and a cover beam are cast, a support device is embedded in the cover beam, and a connecting reinforcement and a steel pipe reserved hole are arranged on the cover beam; the prefabricated rail beam is lifted on the cover beam; two beams are fixed through high-strength fastening bolts, and are connected with the support device on the cover beam through the connecting components; then, the connecting components and the support device are permanently connected; reinforcement cages are bound outside the connecting components; and finally, concrete is cast to integrate the rail beam and the cover beam as a whole. The continuous beam type rail construction method has the following beneficial effects: construction procedures are reduced; the construction is flexible; the construction efficiency is improved; the construction cost is reduced; no deformation of the rail beam is guaranteed; and the train operation safety and comfort are improved.
