Prefabricated construction method and piers for concrete block piers

摘要

PURPOSE: To shorten construction period of a RC bridge pier and reduce construction cost. ;CONSTITUTION: A part which constitutes a post is standardized with concrete block cement 211 and 212 and reinforcing bar cages 22 and 23 in its construction method. Each stage of bridge pier concrete blocks 21 are connected with segment bolts 213, thereby constituting each concrete block 21. The reinforcing bar cages are inserted into the segments and welded with a structural steel 11 of a foundation 1 and added up. Concrete 20 is cast thereinto and stacked one after another, thereby building up a post 2 on the foundation 1.;COPYRIGHT: (C)1994,JPO&Japio
