摘要： PURPOSE:To continuously control the attitude of a floating body by a method in which prediction calculation of the attitude of the float is repeatedly made for every given time period until a set value is met, and when the difference between actually measured value and predicted value exceeds a given value, the body is automatically controlled to a target state. CONSTITUTION:An automatic attitude control system consists of a calculator 13 to predict the balanced attitude of a floating body, a calculator 14 to predictively calculate correcting amounts for attitude from predicted values in the calculator 13 and a target state set value, a calculator 15 to obtain the optimum distribution of water to be charged and discharged on the basis of correcting amounts calculated in the calculator 14, a controller 16 to control a water-changing and discharging device according to the water to be charged and discharged, calculated in the calculator 15, and an attitude controller 17 to examine for comparision actually measured values and predicted values in the calculator 13. Predictive calculation of attitude is repeatedly made for every given time period by the calculators 13-15 until a set value is met, and the body is automatically controlled to a target state by the controller 17 when the difference between the actually measured value examined there and the predicted value exceeds a given value.

摘要： PURPOSE:To safely and exactly install a floating body by a method in which predictive calculation for the attitude of floating body is repeatedly made for every given time period until a set value is obtained, and when the difference between acutally measured value and predicted value exceeds a given value, the body is automatically controlled to a target state. CONSTITUTION:An automatic control system consists of a calculator 13 to predict the balancing attitude of a floating body, a calculator 14 to predictively calculate correcting amounts for attitude from predicted values in the calculator 13 and a target state set value, a calculator 15 to obtain optimum distribution of water charged and discharged on the basis of correcting amounts calculated in the calculator 14, a controller 16 to control a water-charging and discharging device according to charged and discharged water amounts calculated by the calculator 15, and an attitude controller 17 to examine for comparison actually measured values and predicted values in the calculator 13. Predictive calculation for attitude is repeatedly made for every given time period by the calculators 13-15 until a set value is met, and when the difference between actually measured value examined there and the predicted value exceeds a given value, the floating body is automatically controlled to a target state for positioning of installation.

摘要： PURPOSE:To make sure of coherence in a joining part sealing plate with pressing force by means of buoyancy, by installing a float capable of injection or drainage of water in a lower part of the bottom joining part sealing plate of a concrete structure installed on the top, while adjusting the bouyancy by means of injection or drainage of water to or from the inside of the float. CONSTITUTION:In order to make sure of watertightness in a joining part in time of performing the joining operation of a concrete structure 3 on the sea, a sealing plate 1 of a steel plate is installed on the top of a float 6 capable of injection or drainage of water. In this sealing plate 1, there are provided with rubber packing 4 and a joining part concrete placing mold frame 5. And, a weight for prevention against upwide-downness is installed on a bottom surface of the float 6. Then, with water injection or drainage to or from the inside of the float, buoyancy of the float is adjusted, and watertightness in the sealing plate 1 and each concrete structure 3 are effectively achievable owing to pressing force by the buoyancy.

摘要： PURPOSE:To transport a marine structure to the site safely by towing without falling of the structure, by providing floats which can be flooded or discharged at right and left lower parts and by supporting a marine structure in a floater consisting of floats each of which is connected to each other via upper frame bodies. CONSTITUTION:Floats 3 which can be flooded or discharged, are provided at right and left lower parts. Hollow columns 4 are erected at both fore and aft positions of these floats 3, and each column top is connected to each other with a truss structured frame body 5. The aft ends of floats 3 are also connected to each other by a truss structured frame body 6. The floats 3 are flooded or discharged to adjust their drafts. Then a marine structure such as a concrete caisson or platform is hung down through a supporting piece at the inside of right and left floats 3, and it is towed by sea to the site.

摘要： PURPOSE:To raise the efficiency of water shielding when a grounting agent is filled in spaces by a method in which cut-off plates whose one end is fixed with a grout pipe are fitted into each other and then water jet is injected from the bottom of these pipes to discharge soil and sand in the spaces formed by these pipes, followed by the injection of grouting agent. CONSTITUTION:In a cut-off plate 2, a grout pope 1 is fixed by welding to one side of the body 3, and also an engaged portion 4 with a space enough to insert the pipe 1 is formed at the other end. The first cut-off plate 2 is placed, and then the next cut-off plate 2 is placed by fitting it into the engaged portion 4 of the first cut- off plate 2 already provided with the gout pipe 1. The operation is repeated. When sand and soil is filled in the engaged portion 4 during the construction work, water jet is injected into the bottom of the pipe 1 to discharge the sand and soil from the upper part of the pipe 1. Then, a grouting agent is filled into space of the engaged portion 4 for shilding water.

摘要： PURPOSE:To prevent tumbling of a suction anchor when the anchor is extensibly inserted into the seabottom, by supporting the suction anchor, in which a pressurizing air hose, jet water nozzle, and a pipe performing suction and discharge of air and water in a cylindrical part are mounted to the cylindrical part opened with the bottom end, through a guide part. CONSTITUTION:A suction anchor is connected through a rope 5 from a mother ship 4. The suction anchor is constituted by an anchor main unit, in which a pressurized air supply hose 8, jet water supply nozzle 7, and a pipe 9 performing suction and discharge of water and air in a cylinder 1 are mounted to the cylindrical part 1 opened with the bottom part, and a guide part provided with supporting legs through a power unit 2 arranged in the upper part of the suction anchor. The suction anchor is extensibly inserted into a surface of the seabottom by utilizing water discharge through supply of pressurized air into the cylinder and negative pressure through evacuation of internal air, here the suction anchor is guided in the vertical direction by supporting legs 6 and never tumbled.
