摘要： PROBLEM TO BE SOLVED: To provide a break-down device of underwater base rock and a break-down method of underwater base rock which prevents a wire from being paid off excessively when making a rock crushing bar fall freely and in which work can be conducted easily without unnecessarily reducing the falling speed of the rock crushing bar and without special skill.
SOLUTION: A rock crushing bar supporting frame 7 is grounded to the bottom of water 41 using a main winding wire 11. Then the fixation of a fixing member 12 by a fixing device 10 is released and the fixing member 12 and the rock crushing bar 9 are dropped to crush the base rock at the bottom of water 41. Then the fixing device 10 is dropped in the rock crushing bar supporting frame 7 by a sub winding wire 13. When the fixing device 10 is dropped close to the rock crushing bar 9 the drop of the fixing device 10 is stopped and the fixing member 12 is fixed by the fixing device 10. In this state, the fixing device 10 is raised by the sub winding wire 13 and stopped at a specific height in order to return to the original state. This process is repeated to crush the bottom of water 41.

摘要： PROBLEM TO BE SOLVED: To provide a crushing apparatus for underwater rock mass and a crushing method for underwater rock mass, allowing machinery and materials used to be carried into an inland part, surely specifying a rock crushing position, and easily pulling out a rock crushing bar when it bites into the rock mass.
SOLUTION: A crane 3 on a barge type platform 1 is used, a sheath-like rock crushing bar support frame 7 having a gap 29 is supported by a main hoisting wire 11, and the rock crushing bar 9 disposed in the rock crushing bar support frame 7 is supported by an auxiliary hoisting wire 13. Subsequently, the rock crushing bar support frame 7 is lowered by the main hoisting wire 11, and after a conical installation metal fitting 17 at the lower end is grounded on the bottom 41 of the sea, the rock crushing bar 9 is dropped to crush the rock mass at the bottom 41 of the sea. When the lower end part 39 of the rock crushing bar 9 bites into the rock mass, the rock crushing bar support frame 7 is hoisted by the main hoisting wire 11 to press a frame part stopper metal fitting 25 of the rock crushing bar support frame 7 to a rock crushing bar stopper metal fitting 27 of the rock crushing bar 9 to transmit the force of the main hoisting wire 11 from the rock crushing bar support frame 7 to the rock crushing bar 9, thereby pulling out the rock crushing bar 9 from the rock mass at the bottom 41 of the sea.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a conventional excavator for excavating a bottom baserock in water is difficult to conduct positioning because the excavator is subjected to the effect of a tidal current or the like in the excavator. SOLUTION: The excavator 1 is moved along a leader supported by working crafts 2 floating on a water surface. Accordingly, the excavator 1 is not subjected to the effect of the tidal current or the like. Consequently, positioning to an excavation point is facilitated, and such workhours can be shortened. Since a truss casing 3 vertically drops towards the bottom of the water from the working crafts 2, the length of the truss casing 3 corresponds to excavation depth. Therefore, excavation depth is made clear, and the progress of excavation can be determined easily.

摘要： PROBLEM TO BE SOLVED: To perform stable position control of a floating body by a method wherein the floating body position of a floating body type excavation rig connected to a jet- proof device at a sea bottom through a riser pipe is corrected by a specified formula. SOLUTION: A riser pipe 3 is connected from a floating body 1, floating on a sea surface A, to a jet-proof device 2 arranged on a sea bottom B. A drill pipe inserted through the riser pipe 3 and excavation of a sea bottom is effected. The riser pipe 3 is provided at upper and lower ends with clinometers 4 and 5 to measure inclination angles θT and θB of the upper and lower ends of the riser pipe. A clinometer 11 is also arranged at the jet-proof device 2 at the sea bottom B. The inclination angles θT and θB the upper and lower ends of the riser pipe 3 are inputted from the clinometers 4 and 5 to a computer 6, and a position correction amount δ of the floating body 1 is determined according to a specified formula. An engine 7 for driving a pusher is run, and the floating body 1 is moved in the direction of an arrow mark by the position correction amount δ to correct a position. Further, the specified formula is δ=C.L(θB-αθt )/(1+α ), wherein C is a factor, L is the length of the riser pipe 3, and α is a factor to decide whether a weight is placed on control of the inclination angle of the upper part of the riser pipe or a weight is placed on control of the inclination angle of the lower part thereof.
