post hole auger bits

The construction of the auger should select post hole auger bits according to the geological conditions of the site:
(1) Stroke bedrock: Equipped with a pick barrel-type coring bit--conical Auger Bit Set--a rotary drill bucket with double bottom, or a straight Auger Drill Bit with a pick--a rotary drill with double bottom Dig the drill bucket.
(2) For silt, weak cohesive soil layer, sandy soil, and pebble layer with poor cementation and small particle size, a double-bottom drilling bucket can be used. (3) Hard cement: choose a rotary drilling bucket with a single soil inlet (single and double bottoms), or a bucket tooth straight screw.
(4) Clay: use a single-layer bottom rotary drilling bucket, if the diameter is too small, a two-lobed bucket or a drilling bucket with a soil discharge plate can be used.
(5) Cemented pebble gravel and strongly weathered rock: need to be equipped with conical Extra Long Auger Bit and double bottom rotary drilling bucket (single port for larger particle size and double port for small particle size)
(6) Micro-weathered bedrock: equipped with roller cone-type coring bit-conical Sds Auger Bit--double-bottom rotary drilling bucket, if the diameter is too large, a graded drilling process should be adopted.
(7) Frozen soil layer: straight auger buckets and rotary drilling buckets with small ice content can be used, and conical auger bits can be used with large ice content. It should be noted that the drill bits are used for soil layers (except for Sludge and silt) are effective, but must be used in the absence of groundwater, so as to avoid suction and cause stuck.
