Free-angle high-bearing composite expanded pile
The invention provides a free-angle high-bearing composite expansion pile, and relates to the technical field of rock and underground engineering, the free-angle high-bearing composite expansion pile comprises a cement mixing pile and a rigid pile inserted in the cement mixing pile, the bottom of the cement mixing pile is provided with a special-shaped expansion body, the bottom of the rigid pile is provided with a rigid expansion head, and the rigid expansion head is inserted in the rigid expansion body. The anti-shearing stud is fixed to the outer wall of the rigid pile, core filling concrete is poured into the rigid pile, and the rigid expanded head comprises a rigid reinforcing ring fixedly arranged outside the rigid pile in a sleeving mode and a rigid rib plate welded to the rigid reinforcing ring; the bottom of the rigid pile becomes an expanded head with high bearing capacity and rigid fixed size through the rigid reinforcing ring and the rigid rib plate, the technical problems that the bearing capacity is unstable and the discrete type is large are solved, and the problem that the diameter ratio between an outer-layer cement stirring expanded body and the rigid pile is too large is solved by forming a two-layer progressive rigid structure body. Therefore, the purpose of greatly improving the bearing capacity and the pulling resistance of the pile foundation is achieved.
本发明提供一种自由角度高承载复合扩体桩，涉及岩土及地下工程技术领域，包括水泥搅拌桩和插设在水泥搅拌桩中的刚性桩，水泥搅拌桩的底部设置有异形扩大体，刚性桩的底部设置有刚性扩大头，且刚性扩大头插设在刚性扩大体中，还包括固定在刚性桩外壁的抗剪栓钉，刚性桩的内部浇筑有填芯砼，刚性扩大头包括固定套设在刚性桩外部的刚性加强环和焊接在刚性加强环上的刚性肋板；通过刚性加强环和刚性肋板使得刚性桩的底部成为一个高承载有刚性固定尺寸的扩大头，解决了承载力不稳定，离散型较大的技术问题，通过形成二层递进刚性结构体解决了外层水泥搅拌扩大体与刚性桩之间直径比过大的问题，从而达到大幅度提高桩基承载力及抗拔力的目标。
