Steel pipe column construction casing rotator

The vertical insertion of steel pipe column is often used in the construction of underground structure with cover excavation method. This process uses the advanced functions of the full rotary casing drill, such as precision positioning, verticality monitoring and adjustment, vertical insertion, etc. to assist other accurate detection technologies, so that the underground permanent (or temporary) steel pipe column can be inserted with high precision, the vertical degree is not less than 1/500, and the single insertion operation time is only 4 hours, which is more efficient and more accurate than the conventional construction operation. The construction efficiency is greatly improved and the construction cost is reduced. The full rotary casing drill is suitable for the vertical insertion of various types and sizes of steel pipe columns, and will become the mainstream and conventional construction method in the future.
