However, during borehole grouting pile construction of the present, round section piles are used universally. Generally speaking, the boreholes are drilled by a large diameter round piling bit. Because of the restriction of factors of the mud pumps, and drilling equipments, and drilling technique, it would result in such problems as fol lowing: a bigger cutting area and overlarge cuttings volume, and more hole bottom sediments, difficult cuttings discharging, and serverely repeat cuttings breaking, and using more concret grouting amount, and lower drilling speed, faster bit wearing, and longer working period, bigger material and labor ex haust, and higher engineering cost, unreasonable ratio of loading capacity to volume of pile foundation, and lower comprehensive economic benefits, and so forth.

然而,钻孔灌注桩施工中,目前最为普遍采用的是圆形断面桩基,一般采用大口径圆形基桩工程钻头,由于国内生产的泥浆泵、钻具及钻进方法等因素的限制,从而使钻孔破岩面积和体积过大,造成孔底沉过多,排困难且排浆量大,重复破碎问题突出,混凝土灌注量大,直接反映为钻进效率低、钻头磨损快、施工工期长、材料能耗和劳动消耗大、工程成本较高、桩基荷载能力与体积比不合理、综合经济效益不理想等,这些问题严重影响和制约着钻孔灌注桩施工技术的发展和进步。
