Novel construction method for implanting PHC (Prestressed High-strength Concrete) grouting pedestal pile through cement soil stirring
The invention discloses a novel construction method for implanting a PHC grouting pedestal pile into cement soil through stirring. According to the construction method, firstly, construction preparation is carried out, pile position lofting is carried out according to a drawing, then cement mixing pile construction is carried out, then a PHC pipe pile is implanted into the pile, and cement grout is manufactured after a pile machine is aligned and leveled. After the PHC pipe pile is set, the PHC pipe pile is pressed into the cement mixing pile in a static pressure mode, cement mortar is prepared, the cement mortar is injected into the PVC waterproof geotechnical cloth bag at the bottom of the pile through a grouting pipe, and a cement mortar consolidation body is formed through hardening. And finally, grouting is conducted on the pile bottom through a high-pressure grouting pump, and bottom expanding forming is conducted. According to the construction method, the bearing capacity and the pulling resistance of the pile foundation are improved, meanwhile, the construction efficiency is high, the cost is low, quality control is easy, and the construction method is suitable for building engineering construction under underground complex conditions.
本发明公开了一种新型水泥土搅拌植入PHC注浆扩底桩施工工法；本发明首先进行施工准备，并根据图纸进行桩位放样，然后进行水泥搅拌桩施工，之后将PHC管桩植入桩内，并在桩机对位调平后制造水泥浆液。PHC管桩设定完毕后，再通过静压方式将其压入水泥搅拌桩内，进行水泥砂浆制备，并通过注浆管将其注入桩底PVC防水土工布袋内，硬化形成水泥砂浆固结体。最后，采用高压注浆泵对桩底进行注浆，以进行扩底成型。该施工工法提高了桩基的承载力和抗拔能力，同时施工效率高，成本低，易于质量控制，适用于地下复杂条件的建筑工程施工。
