The basic cast-in-place piles of the traffic sign pole should be simple and fixed to ensure the three-dimensional level of the cast-in-place plate of the cast-in-place plate, that is, the relative height of the level is accurately measured in the two directions of vertically dividing the basic cast-in-place plate, and the bubbles must be vertically centered; the basic cast-in-place concrete of the camera pole must be compact to avoid hollowing of the concrete wall; during the construction period, when the opening is gradually opened, a plastic box or other raw material sealed embedded parts branch pipe is used. Concrete will leak into the embedded parts pipe during the entire concrete pouring process, causing the embedded parts pipe to be blocked.
Most of the pipelines laid at the bottom of the traffic sign pole use PCV pipes. In the case where possible, a layer of 95 bricks or gravel concrete protective layer must be paved at the top of the pipeline to prevent the vehicle from rolling and destroying the pipeline; after the pipeline canal is excavated by the foundation pit, the pipeline will be basically compacted and punished to avoid pipeline deformation caused by the settlement of the base ground after the pipeline is laid; the backfill soil on the pipeline must be compacted every 5cm and then restored to the ground; the branch pipe leading to the kiln well should be extended 3~5cm outward, and all kinds of burrs at the branch pipe should be eliminated.
