How deep are the telephone pole pits and telephone pole pits dug?

The standard embedding formula of telephone poles is: the length of pole body ×0. 1+0.7= buried depth, which is only the minimum value. If it is lower than the minimum, it will be unqualified when it is examined and approved by the bureau. Generally, about 30 worksites will be deepened during construction, and the buried depth of18m is 3m. If it was a copper sleeve, it wouldn't be so deep.

Matters needing attention after installing telephone poles

The clods filled in the pit should be broken.

35kV overhead power line foundation pit should be compacted once every 300mm backfill; 10kV and below overhead power line foundation shall be compacted once every 500mm.

For soft soil foundation pit, compaction times should be increased or reinforcement measures should be taken when backfilling.

After backfilling, the pole foundation pit should be provided with anti-settlement soil layer, the upper area of the soil layer should not be less than the pit area, and the height of soil lifting should be 300mm higher than the ground.

When the landslide is left by the pole-holding upright, the landslide body ("backfill soil") should be compacted and the anti-settling layer should be left.

Tips: Pay attention to safety when digging holes or burying telephone poles. If it is manual operation, please make a safety plan before construction. If it is mechanical construction, please check the condition of the machine before construction and evacuate the surrounding personnel during construction.
