SCOUR PREVENTION POST OF A BRIDGE WELL FOUNDATION FOR PREVENTING A PIER FROM BEING SCOURED BY COMBINING A SCOUR PREVENTION BLOCK WITH A SPIRAL ROTATION FIXING FRAME OF THE WELL FOUNDATION INSTALLED AT THE LOWER END OF THE BRIDGE PIER

摘要

PURPOSE: A scour prevention post of a bridge well foundation is provided to restrict a bridge from being scoured by flux by installing a spiral rotation fixing frame at the outside of a well of a pier right after mounting the pier and installing naturally a scour prevention block to the lower end of the rotation fixing frame by gravity. CONSTITUTION: A scour prevention post of a bridge well foundation for preventing the bridge well foundation mounted at the lower end of a pier of a bridge from being scoured is composed of a scour prevention block(11) and a spiral rotation fixing frame(12). The scour prevention block has a rotary wheel(111) mounted at the lower side, a plane outer portion, and a streamlined inner portion. The spiral rotation fixing frame comprises an inner hollow portion(121), a spiral scour prevention block mounting groove(122) formed on the outer peripheral surface and extended from the upside to the lower side, a rail unit formed in the scour prevention mounting groove to roll the scour prevention block, and a guide unit(124) extended from the rail unit to prevent the scour prevention block from being separated.
