if the measuring distance is smaller than the preset range of the preset value, reducing the position of the reserved template groove on the track bed plate;
2) utilize the step of vertical lead screw adjustment chevron shape drainage slope's direction, include:
adjusting the top end of the vertical screw rod nut to be in contact with the bottom of the steel rail;
measuring the gradient and the direction of the herringbone drainage slope by using a steel rolling ruler and a square ruler;
if the measuring gradient is larger than the preset value, the position of the reserved groove template on the track bed plate is reduced within the specified distance range between the bottom panel and the bottom of the steel rail, and the distance between the adjusted M16 nut and the top end of the screw rod nut is controlled within the preset range;
if the measuring gradient is smaller than the preset value, the position of the reserved groove template on the track bed plate is increased within the specified distance range between the bottom panel and the bottom of the steel rail, and the distance between the adjusted M16 nut and the top end of the screw rod nut is controlled within the preset range.
