Abstract: Provided is a structure for operating a watertight door by use of buoyancy. The structure includes: a detention tank for storing rainwater flowing from a street inlet; a buoyant member which is installed in the detention tank; and a sensor installed in the detention tank, in which if the buoyant member raised by the buoyant of the rainwater collected in the detention tank comes into contact with the sensor, the watertight door is automatically operated. The watertight door structure manually operated at localized heavy rain is improved, and the watertight door is automatically operated if the water level reaches the predetermined level.

Abstract: Provided are a system and method for reinforcing and protecting a reinforced concrete structure in which a reinforced concrete structure is divided and corrosion factors of the divided cross-sectional regions are monitored to automatically supply a protection current to each of the divided cross-sectional regions, thereby actively performing protection of the reinforced concrete structure, and also, by adjusting the level of a protection current according to the progression of corrosion in each divided cross-sectional region of the reinforced concrete structure, power consumption required for protection is optimized and protection is effectively performed, and also by disposing a carbon fiber textile grid in the surface of the reinforced concrete structure to be employed as both a reinforcement member and an anode of the reinforced concrete structure, microcracking which may occur in concrete curing is inhibited and thus permeation of moisture or a chloride into the surface thereof is prevented.

Abstract: The present invention provides a wave-shaped grouting bulb (100) for securing an underground bearing capacity of a steel bar (10), the bulb comprising a plurality of protrusions (120), which have a predetermined maximum diameter (D1) and are formed along the longitudinal direction of a cylindrical pillar part (110) extending downward, wherein the neighboring protrusions (120) are formed to be spaced from each other by a predetermined formation distance (s). The present invention has an advantageous effect of improving a skin friction force and resistance to compression and pullout in the grouting bulb integrated with the steel bar and thus enhancing structural stability in the micropile body.

Abstract: Provided are a facility management system and method using an Internet of things (IoT) based sensor and an unmanned aerial vehicle (UAV). The facility management system and method may determine a current status and an abnormal behavior of a facility by primarily measuring the abnormal behavior of the facility in real time by a plurality of IoT based sensors included in the facility and secondarily precisely measuring the abnormal behavior of the facility by capturing an image through a UAV when necessary or when the abnormal behavior is detected, and may prevent a false alarm due to an error of a measurement sensor by performing two inspections through the IoT based sensor unit and the UAV.
