Pull-out type steel pipe pile with bottom expanding device
The invention relates to a pull-out type steel pipe pile with a bottom expanding device, and belongs to the technical field of pile foundation engineering. Comprising a steel pipe pile body and a bottom expanding device, the bottom expanding device is arranged at the bottom of the steel pipe pile body, and the bottom expanding device comprises a telescopic assembly which is located in the steel pipe pile body and can stretch out of the outer wall of the steel pipe pile body. When the steel pipe pile body sinks into a soil body through piling operation and reaches the designed depth, a bottom expanding device arranged at the bottom of the steel pipe pile body is used for expanding the bottom of the steel pipe pile body and comprises a telescopic assembly which is located in the steel pipe pile body and can stretch out of the outer wall of the steel pipe pile body. And after the steel pipe pile body reaches the designed depth, piling operation is stopped, the telescopic assembly is started, the telescopic assembly extends outwards from the interior of the steel pipe pile body and abuts against and extrudes a soil body at the bottom of the steel pipe pile body, and therefore the end bearing capacity of the steel pipe pile body is increased, and the bearing capacity of the steel pipe pile body is greatly improved.
本申请涉及一种具有扩底装置的可拔脱式钢管桩，属于桩基工程技术领域。包括钢管桩本体和扩底装置，所述扩底装置设置于所述钢管桩本体底部，所述扩底装置包括位于所述钢管桩本体内，可伸出于所述钢管桩本体外壁的伸缩组件。当钢管桩本体通过打桩操作沉入土体，并达到设计深度后，使用设置于所述钢管桩本体底部的扩底装置来对钢管桩本体底部进行扩展，该扩底装置包括位于所述钢管桩本体内部，并且可伸出于所述钢管桩本体外壁的伸缩组件，在钢管桩本体达到设计深度后，停止打桩操作，并启动伸缩组件，使得伸缩组件从钢管桩本体内部向外延伸并抵触挤压钢管桩本体底部的土体，从而增大了钢管桩本体的端承力，从而大幅提升了钢管桩本体的承载力。
