Abstract

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.

First claim
