Turnout laying: Positioning turnout loft. Establish and retest Track Engineering Survey Control Network. Turnout before construction, review of orbit control network and elevation control network. Set turnout construction survey control network. Turnout in situ during the pre-assembled high-quality coal rail turnout, turnout position control point set mine track turnouts, in order to prevent the control points are damaged during construction, at the boundary control points corresponding setting retaining pile foundation, after looking for quick ballast corresponding points. Pile turnout turnout turnout Surveying staked except the heart, the first fork, fork tail bit outside the center of the pile, the turnout should be around 50 ~ 100m range measured discharge line midline pile in order to control the line smooth connection with the turnout. Turnout laying: After the initial adjustment turnout, turnout dedicated the entire road vehicle based on the total station and water level data on the turnout were up ballast, from the road, and tamping. ① the ballast, from the road, near to the design elevation tamping coal rail turnout model, should be reserved for switch tamping machine tamping of the amount from the Road. ② continuous use turnout tamping machine tamping and stabilized the car stable, tamping, stability of not less than three times the density of the track bed should meet the design requirements. Large parts of the tamping machine can not work, you should use a small tamping machine with tamping. ③ turnout tamping machine should not be changed using the sleeper spacing job. ④ After completion of the laying of the track bed section shall comply with the design requirements.
