Chaining on Sloping Ground (Simple Notes) When measuring distances on a hill or slope, we always need to find the flat horizontal distance , not the actual sloped ground distance. There are two main ways to do this: 1. Direct Method (Stepping Method) In this method, you measure the flat horizontal distance directly on the field by creating small, flat steps. Best For: Short, bumpy, irregular, or gentle slopes. How it works (Step-by-Step): Start: The Follower holds the 0-end of the tape flat on the starting ground point A. Stretch: The Leader pulls a short, comfortable length of the tape forward and lifts it up until it looks perfectly flat and straight by eye judgment. Drop: Because the front end of the tape is hanging in the air, the Leader drops a plumb-bob (a weight on a string) down to find the exact vertical point on the ground. Mark & Repeat: They stick an arrow into that ground point. The Follower moves to this new arrow, and they repeat the steps all the way u...
Important interview Questions for QA/QC civil engineer. Q1) How will trucks be checked on site when reciving concrete. Ans- (1) Revolution counter revolution counter for a concrete mixing truck which selectively records the mixing drum revolutions and also records those revolutions of the concrete mixing drum which occur Within a preset drum speed range. The structural qualities of concrete are affected by too much or too little mixing and, as a consequence, it has become important to determine how many mixing revolutions have taken place between the time that the concrete ingredients are deposited in the mixing drum and the time that the mixed concrete is discharged from the truck. Additionally, all revolutions of the concrete mixing drum are not mixing revolutions per se. Only those revolutions of the mixing drum which occur within a predetermined range of revolutions per minute are termed mixing revolutions. A generally accepted rate of rotation o...
