CONSTITUTION:A spud 5 equipped with a spud carriage 6 is provided in front of a rear float 2, and two spuds 7 are provided on both sides behind the float 2. In addition, floats 1 and 2 are connected to each other via the insertion of a spud 5 through a spud hole formed behind the front float 1. Then, two spuds 7 of the rear float 2 and the spud 5 are lowered to the sea bottom B and while one swing winch 10 is being unwound, the other winch 10 is wound. Thereafter, a dredging work is performed with a cutter equipped pump 3, while the float 1 is being swung about the spud 5. According to the aforesaid construction, working efficiency can be improved without use of any anchor for swinging.

摘要： PURPOSE:To transfer cargos between a quaywall and the deck of a ship so as to shorten a cargo handling time and attain a safe operation by appropriately arranging transport passages for horizontal movement of cargos connecting togther a cargo terminal, the quaywall, transport passage bases, and the deck of a ship. CONSTITUTION:After leading a ship to a predetermined mooring position, the hull is lifted by means of a hull elevator device 3, and then a movable pontoon 4 is moved and fixed so as to be in response to the size and the construction of the ship. The transport passage 11 on transport passage bases 10, 13 on one side or both sides of the ship is conformed to the transport passage 15 on the deck 14 of the ship in height. A cargo is previously put in stand-by on one transport passage base with the elevator device, and unloading of the cargo loaded on the ship and loading of the cargo in stand-by are simultaneously performed. The transport passage 11 on the transport passage bases with the elevator devices loaded with the cargo having been loaded on the ship are conformed again to the transport passages 51, 52 of the quaywall 1 in height, and the cargo is moved to a terminal.

摘要： PURPOSE:To decrease an amount of water used to a minimum value, by a method wherein a spread pipe, through which sand can be spread right therebelow, and a jump pipe, through which sand can be spread in a horizontal direction from a ship hull, are provided, and this enables sand to be spread even if the depth of water is low. CONSTITUTION:In a sand spreading ship which is used in water carriage practice, by which a soft ground is covered with soil, a spread pipe 2, through which sand can be spread right therebelow, and a jump pipe 4, through which sand can be spread in a horizontal direction from a ship hull, are provided. A valve 5 and discharge ports 6 and 8 are situated to each of pipes 2 and 4 an energy-reducing surrounding is attached to a discharge port 6 of the spread pipe 2, and this enables sand to be spread within a range limited to a specified area without diffusing sand in water. The utilization of the jump pipe 4 permits sand to be effectively spread in even the corner part of an embarkment where the depth of water is too low to allow enterance of a ship. This, in either case, enables an amount of water used to be decreased to a minimum value necessary to a construction work.
