摘要

PURPOSE: An alarm apparatus for the safety of a bridge is provided, in which alarm is installed to inform the state of the bridge when a water level increase in a flood. CONSTITUTION: An alarm apparatus(500) for the safety of a bridge is installed on a bride composed of a pier(100), a pot bearing(200) and a bridge slab-girder(300). The alarm apparatus(500) includes a connecting member, a measurement pin, an operational pin, a detecting sensor and a transmitter. The connecting member is supported to the top and side of the pier(100) by welding the round plate and fixing it to the top with a set anchor. The measurement pin is formed in a shape of buoyancy box and the buoyancy box is inserted into the connecting member by forming the round connecting hole on the side of the buoyance box. The detecting sensor is provided with the operational pin at one side of the detecting sensor box and the transmitter at the other side of the detecting sensor box. And, the alarm device is capable of alarming the emergency situation by transmitting the electronic wave received from the detecting sensor.
