Turnout construction: technical requirements. Turnout location should meet the design requirements. Turnouts turnout crossing symmetry model in CWR laying area, within turnout rail corresponding location should meet the design requirements. When ordering turnout, according to the design drawings should cross symmetry turnout plant, determine the number and location within turnouts welding and adhesive joints, and clearly the welding method, the turnouts length amount reserved for technical processing. Shop front fork pre-coated ballast to meet the requirements. Turnout handling, transport and storage: bifurcated tip rail and the stock rail assembly, with movable nose frog assembly, with a length greater than 15 meters of track and boxed parts crossing symmetry turnout rates, should use large-scale lifting mechanical handling. When lifting ropes hanging point should be arranged on both sides of the workpiece center of gravity, does not allow a single point lifting. Lifting should slowly rise and fall, the workpiece to prevent collisions. Under turnout components must be square wooden support pad, support pad height of not less than 0.2m.
