1. A pier hatch control system for separation of a bonded zone and an unbonded zone from each other in broad areas accessible to persons and in cruise ports, the pier hatch control system comprising:
a hatch having steel construction profiles and plates of concrete coating on the steel construction profiles, wherein said hatch is located in parallel to ground so as to raise upwardly from one surface on the ground such that said hatch creates a barrier between the bonded zone and the unbonded zone when opening upwardly on the ground;
an actuator connected to an interior of said hatch, said actuator cooperative with said hatch so as to rotate said hatch between an open position and a closed position;
a hydraulic power unit connected to said actuator so as to transmit power to said actuator; and
a control center connected to said hydraulic power unit so as to transmit commands to said hydraulic power unit so as to rotate said hatch between the open position and the closed position.
