(1) The installation of the
fence netting posts should be consistent with the design drawings and coordinated with the road alignment.
2. The uprights should be firmly buried in the soil to reach the design depth and perpendicular to the road surface.
3. The pillars of general road sections can be constructed by driving in, and they should be accurately positioned during construction. When driving too deep, all columns must be pulled out, and the foundation must be compacted before being driven again.
24. When the driving method cannot be used, the excavation method can be used to bury the columns. When setting up a column, fill the soil with good materials and compact it in layers (the thickness of each layer should not exceed 15cm). The compaction of the fill should not be less than the adjacent undisturbed soil. Pillar pits in the rock should be backfilled and compacted.
5. The column can be installed by drilling method. After positioning the pillars, the same material as the subgrade should be used for backfilling and layered and compacted.
26. When pillars are installed on the pavement, the pillar pits are backfilled and compacted with the same material as the roadbed 5cm from the subgrade to the surface, and the remaining parts are backfilled and compacted with the same material as the road surface.
VII. After the column is installed, its horizontal direction and vertical direction should form a smooth line.
8. The transition section of the guardrail and the column at the end shall be installed according to the coordinates specified in the design.
