The chain survey is the whole are survey is divied into a network of triangles and the sides of the several triangles are measured quickly in the field with chain or tape. Each link is 2.0625 feet long. Chain survey is suitable for the survey of areas that are fairly flat and small areas with simple details. Equipment used in chain surveying. I know this is the relief to those who are afraid of mathematics Cross staff or optical square. The link 1. What is Chain Surveying in Civil Engineering? (ii) A metallic tape 20 m or 30 m in length. It has been superseded by the steel tape and electronic equipment. Tape. The chain surveying is the most commonly used surveying for quick and short measurements. Types Of Chains Used In Surveying 1. For example measuring rods can be replaced with measuring tape. Metric surveying chains. Indirect Ranging. Walk the whole area and thoroughly examine the ground, note the position of boundaries, road, and river etc., various difficulties to chain lines, select stations, and prepare neat sketches called index sketches or key plan. Metric Chain (20 m) 1 no. 3. If carefully done, it gives quite accurate results. Wooden pegs. Surveying equipment is being used under most stressful conditions. In this method, the lengths of lines marked on the field are measured, while the details are measured by offsets and ties from these lines. Engineers chain 5. It gets its name from the fact that the chain is the most widely used piece of equipment. Equipment used for chain surveying: Tapes, Ranging rods, Arrows/Marker paint, Prism Square, Prismatic Compass Booking Chain and tape are easy to use and anyone can use once they are given some basic training. What is a primary chain? This method is time consuming. Chain or Tape. Advantages Of Chain Surveying.
