Standard for Curve Marking Oil Brush
The positive vector of the curve, the measuring point number, the super high, the gauge widening and so on are marked. The standard is uniform, 60 kg / m and 50 kg / m line, 35 × 50 mm red bottom line, 90 × 180mm.43kg/m line, 30 × 40 mm red bottom line and 80 × 170 mm red bottom line.
When there is an easement curve, oil brushes are applied to the inner side of the upper thigh rail on the outside side of the straightening point and the slow point; When there is no transition curve, the outer side of the straight dot and the straight point of the circle are oil brushed on the inner side of the upper thigh rail, respectively. The width of the red bottom of the rail is 90mm / 43kg / m and the width of the red bottom of the rail is 80mm. The length is determined according to the specific situation. The interval between the red base of the curve element and the normal vector red base of this point is 20 mm.. The order of the elements of the curve is as follows:
R=2000 L=29814 l=80 h=50 F=25
The curve has gauge widening and also indicates the gauge broadening value.
R=2000 L=29814 l=80 h=50 F=25 S=5
