Pile foundation drilling device for civil engineering
The invention relates to the technical field of drilling, in particular to a civil engineering pile foundation drilling device which comprises a drill bit, an annular groove, a hinge block ejection device, a spiral blade and a U-shaped clamping groove. According to the device, drilling can be conducted through rotation of the spiral blade, soil can be conveyed out of a hole through rotation of the spiral blade, and meanwhile steel bars can be conveyed into the hole in sequence by forming a U-shaped clamping groove in the outer side of the spiral blade; the hinged block ejection device is matched with the sectional type spiral blade, so that the reinforcing steel bar can be bent and clamped in the pile foundation hole, the stability of the reinforcing steel bar in the vertical direction can be maintained, the pile foundation hole can be prevented from collapsing through blocking and protecting of the reinforcing steel bar, then the reinforcing steel bar in the pile foundation hole is matched with the steel ring cage, and lateral deviation of the steel ring cage can be prevented through the overall guiding effect of the reinforcing steel bar; and finally, concrete is poured into the pile foundation hole, so that the formed pile foundation base is firmer, and the safety of subsequent building construction is improved.
本发明涉及钻孔技术领域，具体涉及一种土木工程用的桩基钻孔装置，包括钻头、环形槽、铰接块顶出装置、螺旋叶片和U型卡位槽；此发明不仅可以通过螺旋叶片旋转进行钻孔，还可以通过螺旋叶片旋转将泥土输送出孔外，同时通过对螺旋叶片外侧开设U型卡位槽还可以将钢筋顺送至孔内，再通过铰接块顶出装置配合分段式螺旋叶片可以将钢筋顶弯从而卡在桩基孔内，既能维持钢筋于竖直方向的稳定性，钢筋的挡护还能防止桩基孔崩塌，再将桩基孔内的钢筋与钢圈笼配合，钢筋整体的导向作用可防止钢圈笼侧偏，则使得桩基孔的钢筋骨架更加稳定，最后将桩基孔内浇筑混凝土，从而使得形成的桩基底座更加牢固，为之后的建筑修建提升了安全性。
