You can use a flexible PVC pipe to bend into a natural arc as a reference line for the direction of the garden road.
The specific location can be fine-tuned based on the drawings and actual on-site conditions to ensure smooth park lines (it is recommended to use ?25mm pipe diameter). When encountering arc segments at road intersections, attention should be paid to the edge materials according to the on-site The arc is processed twice.
Bring the laying-out tools and drawings to the site, and measure and stake out the adjacent structures connected to the circular structure, so that when the circular structure is laid out, it can be closed to check whether there are any errors.

Notes on arc setting out for road construction:
1. Users should pay attention to whether the distance and direction between each intersection are consistent with the drawings ; If a project has several bidding sections, attention should be paid to whether the center of the adjacent bidding sections is closed, and the center line measurement should be 50 to 100 meters deep into the adjacent bidding sections.
2. Users need to pay attention to whether the centers of structures such as bridges and culverts are closed; they should pay attention to whether the relative positions of buildings and other buildings are consistent with the drawings. If problems are found, contact the design unit promptly to find out the cause.
3. Setting of guard piles. The installation of road centerline piles and protective piles is an important basis for roadbed construction. However, these piles are easily damaged during construction, so the restoration and testing of centerline piles are often required during roadbed construction. In order to quickly and accurately restore the center line pile to its original position, guard piles must be installed at the main pile points that play a controlling role on the road, such as intersection points, turning points, curve control points, etc. before construction.
