By comparing the side slope sensor or the side slope of one side slope, field sampling and setting value, control the leveling oil tank on both sides to control leveling.
There are many kinds of pavers, and the common paver used on the normal highway is according to the hanging line before the paving. The paver is equipped with leveling instruments, and the instrument can be hung on the line for paving!
Paver for square type, using longitudinal instrument automatic leveling which is elevation, for example it is to ensure the wire paving surface from the wire has a fixed distance, so you wire a little higher, a little lower does not matter, as long as the wire frame after calculating Chutan pavement should be from the wire the distance can be. When the longitudinal joint is used, the longitudinal shoe of the longitudinal wave instrument is directly placed on the paved pavement, which is the same principle. It guarantees the smoothness of the new paving and the paved pavement. The use of longitudinal instrument cannot use a screwdriver or steel to tie the thickness, this is actually wrong.
