Construction of rainwater and sewage pipe networks
1. Measurement and positioning of pipeline lines
Before measuring, check the level points to meet the specification requirements.
During the measurement process, temporary leveling points should be set up along the pipeline route. The distance between the leveling points should not be greater than m and should be closed to the original leveling points. Construction level points should be numbered in sequence and the corresponding elevations should be measured.
If the pipeline route intersects with the original underground structure, the location must be marked with a sign on the ground.
The alignment measurement process should be accurately recorded, and all level points and connecting lines should be marked.
. According to the drawings and the control points disclosed on site, retest the pipeline and well position, do a good job of pile inspection and tie-point work for the center pile, directional pile and fixed well position pile, and measure the elevation closure difference to meet the specification requirements. .
If the piles are found to be misplaced or missing during the construction process, they should be corrected or repaired in time.
