5. Specific steps to find the square control line
1.Determine the reference point: First, you need to find a known coordinate point or building corner point as the measurement benchmark.
2.Choose the right tool:Select measurement tools based on accuracy requirements and site conditions.
3.Establish control network: Establish a network of control points through measurements to ensure each control point verifies each other.
4.Staking out positioning: According to the design drawings, stake out the key points of the square control line on the ground.
5.Review check: Use different methods or tools to review to ensure that the position of the square control line is accurate.
6. Common problems and solutions
| Problem description | Possible reasons | solution |
|---|---|---|
| Large deviation of square control line | Wrong reference point or instrument not calibrated | Recheck the reference point and calibrate the instrument |
| Unable to close measurement | Control point spacing is too large | Add intermediate control points |
| Data is inconsistent | Mixing different measurement methods | Unified measurement methods and accuracy standards |
| Marking is not clear | Use temporary marking materials | Switch to the Durability Marking Method |
