Cast-in-place concrete pile with pile end reinforcing body capable of providing pulling resistance and construction method
According to the cast-in-place concrete pile with the pile end reinforcing bodies capable of providing the pulling resistance and the construction method, after the pile end reinforcing bodies such as a stirring pile and a jet grouting pile are implemented, the reinforcing materials are arranged in the reinforcing bodies and anchored to the cast-in-place concrete pile or a bearing platform, the reinforcing bodies can also bear the pulling resistance effect, and prestress can be applied when necessary. Therefore, the reinforcing body not only can increase the bearing capacity of the pile foundation and reduce deformation, but also can bear an anti-pulling effect, good deformation bearing performance is obtained on the premise that the manufacturing cost is slightly increased, and the reinforcing body has wide application space in the field of geotechnical engineering.
本发明提供一种桩端加固体可提供抗拔力的混凝土灌注桩及施工方法，在搅拌桩、旋喷桩等桩端加固体实施后，通过在加固体中设置筋材并将筋材锚固到混凝土灌注桩或承台上，使加固体也可承担抗拔作用，且必要时可施加预应力。这样，加固体不仅可增加桩基承载力减小变形，还可承担抗拔作用，在少量增加造价前提下获得良好的承载变形性能，在岩土工程领域的具有广泛应用空间。
