Construction method for improving bearing capacity of cast-in-place concrete pile
The invention discloses a construction method for improving the bearing capacity of a cast-in-place concrete pile. The construction method mainly aims at large-thickness collapsible loess and large-thickness miscellaneous fill backfill sites, the pile end bearing capacity can be greatly improved, and then the pile length and the pile diameter can be reduced; and in addition, due to the fact that asteel pile pipe is adopted for construction, potential quality hazards caused by hole collapse can be avoided, the construction difficulty is reduced, and the cost is reduced. The technology of the construction method has the advantages of being low in construction cost, high in speed, easy in quality control and high in single-pile bearing capacity.
本发明公开一种提高混凝土灌注桩承载力的施工方法，主要针对大厚度湿陷性黄土和大厚度杂填土回填场地；可以大大提高桩端承载力，从而减少桩长和桩径，另外，由于施工采用钢桩管，从而可以避免塌孔造成质量隐患和增大施工难度和费用。本发明技术具有施工成本低、速度快、质量易控制、单桩承载力高的特点。
