Composite pile structure serving as main structure stand column and construction method thereof
The invention discloses a composite pile structure serving as a main structure stand column and a construction method of the composite pile structure. The composite pile structure comprises a precast pile with brackets, wherein the precast pile is in a sectioned type, a pile head is arranged at the pile bottom of the precast pile, one bracket is arranged on the pile top of the precast pile, a through hole is formed in the center of the precast pile, a reinforcement cage is arranged in the through hole, and the through hole in the center of the precast pile is filled with grouting materials; the composite pile structure is used as the main structure stand column in the later period, the underground portion of the sectioned precast pile is wrapped by the grouting materials, a prestressed pipeline is arranged in the wall of the sectioned precast pile, prestressed reinforcing steel is arranged in the prestressed pipeline, and grouting holes are formed in the wall of the precast pile, and communicated with the through hole in the center of the precast pile. The composite pile structure has the advantages that the technological process such as mud wall protection is omitted, so that the construction cycle is shortened; the composite pile structure can serve as a stress component of a main structure, a load-bearing member does not need to be built again, the cost is saved, and pile formation quality is good; the composite pile structure can effectively solve the problem that hole collapse, hole shrinkage, pile breakage and sandwiching of a cast-in-situ bored pile happen in the construction process, and pile formation quality is guaranteed.
