Master Farm Structure and Surveying – Notes, Case Studies & Practical Insights – with Rahul

Degree of Accuracy in chaining

  • The degree of accuracy in chaining is expressed as a ratio called the chaining ratio.
  • Eg: If the error is 0.25m during the measurement of total length of 500m.
  • R = 0.25/500 = 1/2000

 

Adjustment of chain

A. When the chain is too long, it is adjusted by:

  1. Closing up the joints of the ring
  2. Hammering the elongated rings.
  3. Replacing some old rings by new rings and
  4. Removing some of the rings

 

B. When the chain is too short, it is adjusted by:

  1. Straightening the bent ends
  2. Opening the joints of the ring.
  3. Replacing the older ring by some larger ring.
  4. Inserting new rings where necessary.
