The main idea of setting out is to copy the dimensions of the design drawing to the ground according to the dimensions shown in the drawing. Whether the whole project is constructed according to the design drawing size depends on the setting-out.
Extended data:
Foundation lofting method
1, according to the general plan, release three datum control lines (axis, control line and elevation line) in each construction space;
2. On the ground and the top surface, take the central axis as the base point, extend one meter to the working face to be completed, and set the control line of the finished face in parallel;
3. Dimension according to the drawing, and set the completion line of each wall based on the completion line;
4, according to the drawing size, with 1 m horizontal line as the benchmark, caving line;
5. Take the top finish line as the benchmark, extend upward by 250mm, and release the electromechanical control elevation line;
6. According to the drawing size, the ground elevation is 0.00 based on the horizontal line of 65438 0 meters. According to the working face, various lofting methods can be adopted: flowing lofting method and grouping lofting method.
