Prefabricated column for reverse construction method and underground structure reverse construction method
The invention provides a prefabricated column for a reverse construction method and an underground structure reverse construction method using the prefabricated column. The lower portion of the prefabricated column extends into a bored concrete pile. The prefabricated column comprises a concrete column body, reserved reinforcement and annular ribs, wherein the reserved reinforcement is preset at the top of the column body, and at least one annular rib is disposed on each of the periphery of the part, extending into the bored concrete pile, of the column body and on the periphery of the part, corresponding each layer of structural plate, of the column body. By the annular ribs, the combining force between the prefabricated column and the bored concrete pile and between the prefabricated column and each layer of structural plate can be increased, and accordingly the prefabricated column is firmly connected with the bored concrete pile and each layer of structural plate. In addition, due to the fact that the prefabricated column uses the concrete column body, concrete back construction needed by existing steel-latticework columns is omitted, the strength and rigidity of the prefabricated column, namely a whole beam column system are increased as compared with the steel-latticework columns, and up-down synchronous reverse construction is facilitated.
