Expanding guide hole implantable slurry consolidation root consolidation expansion body precast pile
The invention discloses an expanded guide hole implantable slurry consolidation root consolidation expanded body precast pile which comprises an internal precast pile body and a peripheral slurry consolidation body. The internal precast pile is composed of a precast pipe pile, a grouting pipe, a bottom sealing steel plate and a positioning support, the bottom sealing steel plate is fixed to the pile end of the precast pipe pile, the grouting pipe is connected to the side wall of the precast pipe pile through the positioning support, and the peripheral slurry stone consolidation body is formed by filling gravel on the outer side of the internal precast pile through grouting. Technical advantages of a cast-in-place pile and a precast pile are fused, the problems of pile bottom sediment, necking, slurry discharge pollution and the like of a traditional cast-in-place pile can be solved, and the defects that a traditional precast pile has a soil squeezing effect, and pile sinking is difficult in a hard soil layer are effectively overcome; the bearing performance of the whole pile can be greatly improved through the arrangement of the peripheral slurry stone consolidation body, meanwhile, the pile-soil interface side friction optimization and improvement effect and the pile end expansion body enhancement effect are remarkable, and the actual implanting construction requirements of different projects for various special-shaped precast piles are met.
本发明公开了一种扩引孔植入式浆石固结根固扩体预制桩，包括内部预制桩和外围浆石固结体；所述内部预制桩由预制管桩、注浆管、封底钢板和定位支架组成，所述封底钢板固定于预制管桩桩端，所述注浆管通过定位支架连接在预制管桩侧壁，所述外围浆石固结体由内部预制桩外侧填筑碎石经注浆形成。融合了灌注桩和预制桩的技术优点，不仅能够解决传统灌注桩桩底沉渣、缩颈，泥浆排放污染等问题，而且有效克服了传统预制桩挤土效应、坚硬土层沉桩困难的缺陷；外围浆石固结体的设置更是能大幅提升整桩承载性能，同时桩土界面侧摩阻优化提升效果和桩端扩体增强效应显著，解决了不同工程实际对于各类异型预制桩的植入施工需求。
