Preloading harsh concrete pile construction method and control system
The invention relates to a concrete pile for high-rise buildings or heavy loads, in particular to a preloading harsh concrete pile construction method and control system. The method comprises the following steps: one, a pile hole with a designed hole diameter and a designed hole depth is spirally drilled, a goose wing head in the preloading harsh concrete pile construction control system is sunk into the bottom of the pile hole, and the outer diameter of the goose wing head is smaller than the diameter of the pile hole; two, the pile hole is filled with harsh concrete with the strength grade being C30, the Vebe consistence of the harsh concrete is larger than 100 seconds, and the filled harsh concrete is on the position, 2-3m far away from the upper most layer of goose wing of the goose wing head; three, the goose wing head is lifted for n meters in the range of up going 1.5-1.8 meters, and the harsh concrete falls in the space vacated by the goose wing head. The method greatly improves the bearing capacity of the concrete pile, can record the piles in the pile making process, and can detect each pile. The method has the advantages of being high in security, simple in pile making process and low in pile making cost.
