DRY DENSITY OF SOIL BY CORE CUTTER METHOD
TO DETERMINE DRY DENSITY OF SOIL BY CORE CUTTER METHOD Theory: A cylindrical core cutter is a seamless steel tube. For determination of the dry density of the soil, the cutter is pressed into the soil mass so that it is filled...
Measurement of distance with tapes
Precisions for different methods of measuring distances are given below:- Pacing (ordinary terrain): 1/50 to 1/100 Taping (ordinary steel tape): 1/1000 to 1/10,000. Baseline (invar tape): 1/50,000 to 1/1,000,000 Stadia: 1/300 to 1/500 Subtense bar: 1/1000 to 1/7000 Now with technological advances,...
Ranging and Fixing Of Survey Station
The object of this experiment is to set up a survey station. This is the basic step of surveying but this is also the one which has the maximum number of errors. The Equipments used for this are :- 1. Ranging rod...
What is Orthometric Correction?
We know that earth flattens in the polar direction and this curvature of earth is responsible for the departure of horizontal line from a level surface. To counter this error, orthometric corrections is applied. This departure in feet, Cf is calculated asCf= 0.667M2=0.0239F2...
What are the Corrections Applied in Surveying?
For surveying, we need to have some prerequisite conditions. If these conditions are not met we can have a huge variation in result. Therefore we have to apply corrections to get the true result. Ideal Conditions1) A tape accurate to 0.00305m or...
