Title:
仮締切システムおよび仮締切構造体の姿勢制御方法
Document Type and Number:
Japanese Patent JP7200065
Kind Code:
B2
Abstract:
To provide a cofferdam system and an attitude control method of a cofferdam structural body automatically controlling an attitude of the cofferdam structural body.SOLUTION: A cofferdam system is provided with a cofferdam structural body 2, an inclination sensor 31, and a control section. A plurality of reservoir sections 22 are positioned at different positions in a plan view inside of the cofferdam structural body 2. Each of the plurality of reservoir sections 22 is a sealed space capable of storing liquid independently of each other. The inclination sensor 31 measures an inclination of the cofferdam structural body 2. The control section controls charging/discharging water to the plurality of reservoir sections 22 based on a measured value of the inclination sensor 31, and controls attitude of the cofferdam structural body 2 floating on a water surface 97 or the cofferdam structural body 2 being assembled while floating on the water surface 97 by adjusting the amount of water stored in the plurality of reservoir sections 22. Thus, the attitude of the cofferdam structural body 2 can be controlled automatically.SELECTED DRAWING: Figure 10
