Cast-in-place pile construction method suitable for drilling and bottom expanding device
The invention discloses a cast-in-place pile construction method suitable for a drilling and bottom expanding device. The drilling and bottom expanding device is simple in manufacturing structure, free of faults, low in manufacturing cost, easy to operate and beneficial to popularization. The device is the most reliable device for base expansion of various cast-in-place piles at present, and is suitable for pile types such as drilling pressure grouting superfluid mixed bottom piles, dry operation drilling base expansion cast-in-situ piles, drilling grouting base expansion piles, drilling prefabricated composite base expansion piles and the like. According to the bottom expanding construction method, the bearing capacity of one single pile is effectively improved, the manufacturing cost is greatly reduced, resources are saved, and the good market prospect is achieved.
本发明公开了钻孔扩底装置所适用的灌注桩施工方法。钻孔扩底装置制作结构简单，无故障，造价低廉，易操作，利于推广。该装置是目前各种钻孔灌注桩扩底的最可靠装置，适用于钻孔压灌超流态混底桩，干作业钻孔扩底灌注桩，钻孔压浆扩底桩，钻孔预制复合扩底桩等桩型。该扩底工法有效的提高了单桩承载力，大幅度降低了造价，节约了资源，有较好市场前景。
