Beschreibung
Zusammenfassung:	A prefabricated thin-walled hollow pier construction method based on steel bar post-installation, comprising: dividing a pier column into a plurality of prefabricated sections, the plurality of sections being divided into two types of sections, i.e., I-type sections and II-type sections, wherein each I-type section is divided into two straight-plate modules and two U-shaped modules in the longitudinal direction, and each II-type section is divided into four L-shaped modules in the longitudinal direction; providing a main steel bar channel in the main steel bar position of each module, and providing a hoop steel bar channel in the hoop steel bar position of each of some of the modules of each section; installing the I-type sections and the II-type sections alternately at a pier position, during installation of each section, a hoop steel bar being inserted in each hoop steel bar channel and being connected to a preset hoop steel bar by means of a threaded sleeve, and main steel bars being inserted into main ste
