Pile body expanding multifunctional dual-power drilling tool, preparation method and shaped pile
The invention relates to the technical field of civil engineering, in particular to a multifunctional dual-power drilling tool for expanding a pile body, a preparation method and a shaped pile. The multifunctional dual-power drilling tool for expanding the pile body comprises an upper power drilling tool and a lower power drilling tool, the upper power drilling tool comprises an upper power mechanism and a central stirring hammer; the central stirring hammer can rotate in a linkage manner under the driving of the upper power mechanism, and can do axial lifting action under the driving of the winch; the lower power drilling tool comprises a lower power mechanism and a lower sleeve drilling tool; the lower sleeve drilling tool can be driven by a lower power mechanism to rotate in a linkage mode. The lower power mechanism is provided with two feeding ports, one feeding port is used for conveying superfluid concrete, and the other feeding port is used for conveying a dry cement mixture. Through cooperation of the dual-power drilling tool, the hard concrete is rammed and expanded to achieve pile body diameter expansion and pile end bottom expansion (head expansion); and the pile body main body is formed by pressing and filling superfluid concrete/ramming and filling dry hard concrete.
本发明涉及土木工程技术领域，尤其是涉及一种桩身扩径多功能双动力钻具、制备方法及型桩。该桩身扩径多功能双动力钻具包括：上动力钻具和下动力钻具；上动力钻具包括：上动力机构和中心搅拌锤；所述中心搅拌锤在上动力机构的带动下能够联动旋转，同时在卷扬机的带动下能做轴向的升降动作；下动力钻具包括：下动力机构和下套筒钻具；所述下套筒钻具在下动力机构的带动下能够联动旋转；所述下动力机构设有两个进料口，一个进料口用于输送超流态混凝土，另一个进料口用于输送干性水泥拌合物。通过双动力钻具协作，夯扩干硬性混凝土实现桩身扩径、桩端扩底(扩大头)；压灌超流态混凝土/夯填干硬性混凝土形成桩身主体。
