DURABILITY SENSOR FOR CONCRETE IN WATER POURING INTO WELL BOXBASIS FOR BRIDGE

摘要

An apparatus for detecting the durability of concrete in water injected a bridge well foundation is provided to detect a variation such as crack due to deterioration of the durability of the concrete in water through an oil pressure difference of an internal sensor and visually display the durability such that a user easily check the durability. An apparatus for detecting the durability of concrete in water injected a bridge well foundation includes a durability diagnosis box(10) and a durability diagnosis frame(20). The durability diagnosis box includes a fluid storage tank(11), a hydraulic pump(12), a controller(13) for supplying a fluid in the storage tank through a supply pipe, and indicators(15,15a,15b) for visually displaying the injected amount of the fluid. The durability diagnosis frame includes a vertical diagnosis plate(26) buried in the concrete in water, diagnosis cylinders(21,21a,21b) fixed to the top, middle and bottom of the vertical diagnosis plate, and pistons(22,22a,22b) which slides forward according to the pressure of the fluid and transmit a signal to a remote manager terminal when the quantity of the fluid exceeds a predetermined reference value set by the controller.
