cross section of levelling machine

What is the difference between profile leveling and cross

Profile leveling The process of determining the elevations of a series of points at measured intervals along a line such as the centerline of a proposed ditch or road or the centerline of a natural feature such as a stream bed Normally we will as...

Why roller leveling

The machine s design depends on the materials to be leveled The key parameters of a leveling machine include the diameter the roller pitch and the number of leveling rollers Basically the closer the roller pitch and the smaller the leveling roller diameter the better the result...

BASICS OF LEVELLING

A level is set up on a tripod and levelled so that the line of sight is horizontal A graduated staff is held vertically over the first point and a reading made of the intersection of the cross-hair with the image of the staff backsight - b The same or an identical staff is then held vertically over the second point and a further reading...

Principle of Levelling

Reduced level of the line of sight RL= 0 h1 =h1 Reduced level of the point B = h1-h2 With a levelling instrument it is possible to establish only a horizontal line not a level line However for the smalldistances involved in ordinary levelling the distinction between level line and horizontal line is negligible...
