Supporting foundation structure suitable for frozen soil area
The supporting foundation structure suitable for the frozen soil region comprises a pile foundation cylinder, a pile foundation cylinder top seat, a pile foundation cylinder base and a frost heaving piercing mechanism, the pile foundation cylinder top seat is fixedly installed at the top of the pile foundation cylinder, and the pile foundation cylinder top seat is used for being connected with a to-be-supported target; a pile foundation cylinder base is arranged at the bottom of the pile foundation cylinder, and a plurality of threaded drill rod assemblies are arranged on the pile foundation cylinder base and used for being fixed to a foundation. The frost heaving piercing mechanism is fixedly installed on the cylinder wall of the pile foundation cylinder. When frost heaving happens to a soil body, under the effect of frost heaving, the transverse anchor rod of the frost heaving piercing mechanism can transversely pierce into the soil body outwards, so that the pile foundation cylinder and the surrounding soil body are anchored together. In addition, due to the fact that the inner diameter of the vertical straight pipe section of the frost heaving piercing mechanism is larger than the inner diameter of the top bent pipe section, even if the soil body frost heaving deformation is small, the transverse anchor rod can generate large transverse piercing displacement.
本发明提供了一种适用于冻土区的支撑基础结构，包括桩基筒、桩基筒顶座、桩基筒底座以及冻胀刺入机构，桩基筒的顶部固定安装桩基筒顶座，桩基筒顶座用于与待支撑的目标连接；在桩基筒的底部设置桩基筒底座，在桩基筒底座上设置有多个螺纹钻杆组件，用于与地基固定；冻胀刺入机构固定安装在桩基筒的筒壁上。当土体发生冻胀时，在冻胀的作用下，冻胀刺入机构的横向锚杆能够横向向外刺入土体，使桩基筒与周围的土体锚固在一起。此外，本发明由于冻胀刺入机构的竖向直管段的内径大于顶部弯管段的内径，因此即便土体冻胀变形较小的情况下，也可以使横向锚杆产生较大的横向刺出位移。
