摘要： PROBLEM TO BE SOLVED: To secure the quality of a land reclamation material, minimize water pollution, supply the land reclamation material without problem even if a depth of water changes, and continuously place the land reclamation material.
SOLUTION: An underwater placement device 26 is disposed at the side of the hull 20 of an underwater placement ship 12. The underwater placement device 26 includes a tube body 30 which extends linearly and has a large length corresponding to the longitudinal length of the hull 20. A screw blade 34 is disposed in the tube body 30. The tube body 30 is swung by a wire 2804 so that the front end thereof comes to a position apart a predetermined distance from the bottom. The land reclamation material is supplied from a hopper 32 to the tube body 30, pressed forward in the tube body 30 by the screw blade 34 while being fitted to the tube body, and placed on the bottom. During the maintenance, the screw blade 34 and a motor 36 are slid along the extending direction of the tube body 30 by extending and retracting a hydraulic cylinder 42 to eliminate clogging or the like.

摘要： PROBLEM TO BE SOLVED: To provide an underwater concrete placing method capable of securing the quality of a landfill material and minimizing water pollution and feeding the landfill material without troubles even if the water depth varies and further, continuously placing the landfill material while transferring the boat. SOLUTION: An underwater placing device 26 is arranged at the side of the hull 20 of the underwater placing boat 12. The underwater placing device 26 is provided with a tubular body 30 having a rectilinearly long length corrsponding to the fore and aft length of the hull 20. A screw blade 34 is disposed in the tubular body 30. The tubular body 30 is rockably hung by a wire 28 so that the front end of the tubular body is set at a specified distance from the water bottom. The landfill material is supplied from a hopper into the tubular body 30 and force-fed in the tubular body 30 in a state the material is closely stuck by the screw blade 34 and placed onto the bottom of water.

摘要： PROBLEM TO BE SOLVED: To provide an underwater placing method which places a huge quantity of reclamation materials while minimizing water pollution, and to provide an underwater placing instrument and an underwater placing ship. SOLUTION: According to the underwater placing method, the oscillation angle of a tube body 30 is adjusted, and when a lower end of a cylindrical member 54 reaches a sea bottom B, the lower end of the cylindrical member 54 sinks in detritus deposited on the sea bottom B. The reclamation material is squeezed through the interior of the tube body 30 in a manner making close contact therewith by screw blades 34. Then, the reclamation material squeezed out of a lower end 3010 of the tube body 30, collides with a rectifying member 52, and then it is directed toward the interior of the cylindrical member 54, followed by colliding with the interior of the cylindrical member 54, whereby it is upward filled from below in the cylindrical member 54. Further, the reclamation material 54 which has been declined in momentum (flow rate) overflows an upper end of the cylindrical member 54 out of the same, and the reclamation material which has been declined in momentum (flow rate) is sequentially deposited on the sea bottom B at an upper end of the cylindrical member 54 in a spreading manner, to thereby place the reclamation material.

摘要： PROBLEM TO BE SOLVED: To place a large amount of land-fill material while suppressing water contamination to a minimum extent.
SOLUTION: An angle of oscillation of a tube 30 is adjusted, and when the lower end of a cylindrical member 54 reaches a sea bed B, the lower end of the cylindrical member 54 sinks into floating mud deposited on the sea bed B. The land-fill material is pushed ahead inside the tube 30 by a screw blade 34 in a cohesive state. The land-fill material pushed out of a lower end 3010 of the tube 30 hits a rectifying member 52, and it is directed toward the inside of the cylindrical member 54. Then the land-fill material hits the inside of the cylindrical member 54, whereby the inside of the cylindrical member 54 is filled upward from below. Further, the land-fill material with attenuated momentum (flow rate) overflows from the upper end of the cylindrical member 54 to the outside of the same, and the land-fill material with attenuated momentum (flow rate) is sequentially deposited on the sea bed B around the cylindrical member 54 in a spreading manner, so that the land-fill material may be placed.

摘要翻译：要解决的问题：在最小程度上抑制水污染的同时放置大量的填土材料。解决方案：调节管30的摆动角度，并且当圆柱形构件54的下端到达海床B时，圆柱形构件54的下端沉入沉积在海床B上的浮动泥浆填料通过螺旋刀片34以内聚状态被推入管30内。从管30的下端3010推出的填土材料撞击整流构件52，并且朝向圆筒构件54的内侧。然后，填充材料撞击圆筒构件54的内部，由此筒状构件54的内部从下方向上方填充。此外，具有减弱的动量（流量）的填埋材料从圆柱形构件54的上端溢出到其外部，并且具有减弱的动量（流量）的填土材料依次沉积在海上床B以扩展方式围绕圆筒形构件54，从而可以放置填充材料。版权所有（C）2011，JPO＆INPIT
