Rotary drilling rig is a kind of construction machine suitable for hole formation in building
foundationengineering.
Mainly suitable for sandy soil, cohesive soil, silty soil and other soil construction, widely used in
cast-in-situ piles, continuous walls, foundation reinforcement and other ground foundation
construction.
The output torque is 120 ~ 400kN • m, the maximum hole diameter can reach 1.5 ~ 4m, and the
maximum hole depth is 60 ~ 90m, which can meet the requirements of various large foundation
constructions.
1. In terms of suitability for strata, it is not only suitable for cohesive soil, sandy soil and silty
soil, but also suitable for artificial backfill soil and stratum containing some pebbles and gravels,
as well as weathered rocks with low strength.
2. In terms of drilling methods, both wet drilling and dry drilling can be used.
3. In terms of the type of bored piles, both straight holes and inclined holes can be drilled, the
maximum pile diameter can reach 2.5m, and the deepest pile length can reach 100m.
