Double-casing-pipe full-circle-swinging erect column pile construction method
The present invention discloses a double-casing-pipe full-circle-swinging erect column pile construction method. The method comprises the steps of positioning a pile machine, pressing an inner casing pipe dowards, forming holes in the inner casing pipe; cleaning up barriers, hanging and welding steel reinforcement cages, hanging latticed columns at the edge of an inner casing pipe tube, placing tremies, lifting out inner and outer casing pipes and backfilling with coarse sand. The construction method provided by the present invention is suitable for various complicated soil textures, is short in pile-forming time, and can solve the problem of lowering of top elevation of steel columns, the sinkage of the steel columns is controlled within an error allowable range, and the pile-forming quality is ensured.
