Profile leveling is a method of surveying that has been carried out along the central line of a track of land on which a linear engineering work is to be constructed/ laid. The operations involved in determining the elevation of ground surface at small spatial interval along a line is called profile leveling.
Profile levelling is the process of levelling along a fixed line to determine the elevations of the ground surface along the line. Profile levelling is also known as longitudinal sectioning. Use of profile levelling. The ground profile shows the elevations of the ground along the section.
A graphic representation of the sections that are in a linear work, on cutting the axis of the aforementioned work with vertical planes perpendicular to it and defining the trace in elevation. y-axis', perpendicular to this gradient by means of the axis of the trace.
Rise and Fall Method is the method of calculating the difference in elevation between consecutive points in levelling work. Some of the points you have to know before starting numerical are: Back sights: The first reading after seeing the instrument is called back sights.
A backsight (BS) is a sight taken with the level to a point X of known elevation E(X) , so that the height of the instrument HI can be found. A backsight in direct levelling is usually taken in a backward direction, but not always.
In the cross section of roads it is that portion of the roadway between the outer edge of the outer traffic lane and the inside edge of the ditch, gutter, curb or slope.
Temporary Bench Mark (TBM) - a point of known height above a pre-defined level. ... The height of any target point is referred to as Reduced Level (RL), because it is reduced to a known datum. Fig. 1 Levelling line.
Relative level in surveying refers to equating elevations of survey points with reference to a common assumed datum. It is a vertical distance between survey point and adopted datum plane. Thus it is considered as the base elevation which is used as reference to reckon heights or depths of other important places.
Height of Instrument Method. In any particular set up of an instrument height of instrument, which is the elevation of the line of sight, is constant. The elevation of unknown points can be obtained by subtracting the staff readings at the desired points from the height of instrument.
In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.
The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell.
Cutting and filling is the process of moving earth from one place to another to make ground more level. A 'cut' is made when earth is cut from above the desired ground height and a 'fill' is when earth is used to fill a hole to desired ground level.
Earthworks are engineering works created through the moving or processing of parts of the earth's surface involving quantities of soil or unformed rock. The earth may be moved to another location and formed into a desired shape for a purpose. Much of earthworks involves machine excavation and fill or backfill.
The volume of earthwork between sections is obtained by taking the average of the end areas at each station in square feet multiplied by the distance between sections in feet and dividing by 27 to obtain the volume in cubic yards.
Cut: Earth that is removed from an area is considered “cut” or excavated earth.
Fill: Earth that is brought into an area is considered “fill” or embankment earth.
When railways, roads or canals are dug out, the cut material is pushed to fill out nearby hills and embankments. This process is usually accomplished with earthmoving equipment. Bulldozers and excavators remove land .

Nice Sir Ji❤

[@insanethakuryt44]

thank u so much sir ji 🙏🏻🙏🏻🙏🏻
ur videos very helpful 🤗🤗🤗

[@chennareddyindla2349]

Instructor,
You make a dot on LHS, Center, RHS at 0, 5m, 10m,15m.....1000m.
Give TBM value if you know or otherwise 100.
Let all do the Levelling . Check the values them selves whether they got same value or different.
If they do one km Survey that is sufficient to go on highway work.

Everything was going good
Except that guitar noise 😵
Can't listen properly......
Atleast don't play when someone is speaking....🙏
