Study on the Forward Connection of No.9 Single Turnout of 50 kg/m Rail in Railway Special Line
As an indispensable part of China's railway network,railway special line plays an important role in improving the quality and increment of railway freight transportation.Station yard design is the core of railway special line planning and construction,transportation organization and safety production,and is the key to the matching of traffic volume and capacity of railway special line.In view of the requirements of the current railway special line specification for the straight line between the turnouts in the throat area of the station yard,this paper analyzes the structure and characteristics of the current 50 kg/m rail No.9 single turnout(CZ2209),introduces the arrangement of the front and end turnout sleepers of the turnout and the forward connection mode between the turnouts,and puts forward the reasonable length of the straight line section inserted between the turnouts of the new station is increased from 6.25 m to 8.00 m.The solution of 6.25 m is adopted under difficult conditions,and the solution of 6.25 m is adopted between the turnouts in the case of the transformation of the existing station.The actual design work and construction application effect are analyzed,aiming to provide reference for the design and on-site construction of the throat area of the railway special line station in the future.
