Post-treatment construction method for grouting reinforcement of cast-in-place pile
The invention discloses a post-treatment construction method for grouting reinforcement of a cast-in-place pile, and belongs to the technical field of cast-in-place pile construction. Firstly, a grouting hole is drilled in each of the two sides of each cast-in-place pile, then cement-water glass double grout is adopted for grouting, and finally mixed grout of water glass and phosphoric acid is adopted for blocking hole openings. According to the method, a cement-water glass double-grout and cement single-grout mixed grouting reinforcement foundation mode is adopted, the problem of insufficient post-grouting in conventional construction is solved, the pile foundation performance is improved, and the pile body quality and bearing capacity are ensured. The implementation of the method does not damage an original foundation, and is safe and reliable; equipment is simple, operation is easy, convenient and flexible, construction noise is low, and machine operation vibration is small; and the construction cost is low, and the construction speed is high.
本发明为一种灌注桩注浆加固后处理施工方法，属于灌注桩施工技术领域。首先，在每根灌注桩两侧各钻一个注浆孔，然后采用水泥—水玻璃双浆液进行注浆，最后采用水玻璃和磷酸的混合浆液封堵孔口即可。本发明方法采用了水泥—水玻璃双浆液和水泥单浆液的混合注浆加固地基方式，弥补了常规施工中后压浆不足的问题，提高了桩基性能，确保桩体质量和承载力。本发明方法的实施不破坏原地基，安全可靠；设备简单，操作简便灵活，施工噪声小，机具操作振动也小；施工成本较低，施工速度较快。
