摘要： A recyclable pile foundation is provided. The recyclable pile foundation includes several inner cylinders, several outer cylinders and several reciprocating components which are circumferentially distributed between the inner cylinders and the outer cylinders. Each reciprocating component includes several steel collars, a push-pull rod, a hold component and at least one motion component. The motion components are distributed along the push-pull rod. Each motion component includes at least one triangular connection plate, several connection rods, an inner wedge block, an outer wedge block, a motion block and a pointed rod. When the push-pull rod is pushed along its own axis to the pushed position, the pointed rod protrudes from the outer cylinders to increases the friction between the surrounding soil and the recyclable pile foundation. When the push-poll rod is pulled along its own axis to the pulled position, the pointed rods retract back into the outer cylinders.

摘要： Recyclable cylindrical structures and usage methods are provided. A recyclable cylindrical structure includes multiple prefabricated cylindrical units. Each unit is provided with a ring block coaxially fixed on the top of the unit, a ring slot coaxially formed in the bottom of the unit, two first sealing rings arranged on the top of the unit and a second sealing ring arranged on the top of the ring block of the unit. The ring block is provided with multiple first connection elements. Multiple second connection elements are arranged in the ring slot. For two adjacent prefabricated cylindrical units of the recyclable cylindrical structure, the ring block of the lower unit inserts into the ring slot of the upper unit and the first connection elements of the lower unit are corresponding and jammed one-to-one with the second connection elements of the upper unit.
