摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic type driving method and a driving machine therefor capable of driving in without causing any trouble even a driven article hits a boulder stone or a hard layer in the ground. SOLUTION: A steel sheet pile 12 is sandwiched by a case 13 from both sides. A slide plate 16 in the case 13 is pushed against the steel sheet pile 12 by the restoring force of a spring 17. Leakage is prevented by a water stop material 15 and the interior of the case 13 is filled with water, oil, or the like through a fluid filling hole 18. An oscillating element 11 oscillating ultrasonic oscillation is inserted into the case 13 and the oscillating surface 20 is arranged towards the steel sheet pile 12 in the liquid 14 of water or oil or the like. A lifting ring 19 is hanged down with a crane or the like, the steel sheet pile 12 is set on the ground, and ultrasonic oscillation is oscillated from the oscillating element 11.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic vibration head capable of efficiently transferring ultrasonic vibration generated from a vibrator to the soft ground by preventing the incursion of earth and sand, etc., of the soft ground from rod openings. SOLUTION: Square rod openings 12 are symmetrically formed in two places at 180 degrees in a rod 11, and semi-spherical projections 13 adjacent to each of the rod openings 12 are symmetrically formed in two places at 180 degrees. A vibrator 14 of ultrasonic vibration is built in the rod 11, oscillation surfaces 15 of the vibrator 14 are exposed to the rod openings 12. When the rod 11 is rotated in the rotational direction D in the soft ground, the rod openings 12 following from the projections 13 pass through the soft ground, and a gap 16 can be obtained around the rod 11.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for compacting a soft ground wherein a work load can be reduced by propagating supersonic vibrations to the soft ground from the surface of the ground. SOLUTION: In the compacting device 1, five vibrators 11, 12, 13, 14, 15 are connected to a supersonic wave generator 10. A container 16 has a cylindrical bottom portion with a diameter of about 1 m, in which all the vibrators 11, 12, 13, 14, 15 are held, a vibration surface of each of the vibrators being oriented downward. Further, in the container 16, suspension wires are provided at regular intervals along the circumferential direction thereof so that the container is suspended by a back hoe. The bottom surface of the container 16 is put on the surface of a soft ground and a water level surface to generate supersonic vibrations.

摘要： PROBLEM TO BE SOLVED: To establish a method and device for removing internla attachment of a pavement satisfactorily without damaging the pavement and restitute the clogged condition easily and economically. SOLUTION: A function recovering device 10 of a pavement 32 is composed of a wate reception part 11 located in the center, a suction part 12 installed as pinching the part 11, and a ultrasonic oscillator 15 installed in the part 11. Ultrasonic vibration is given to a purifying water in a water receiving mold 18 opening toward the paving surface 36 and constituting the part 11, and the purifying water is supplied to the gap in the pavement 32, and thereby the attachment such as dust is torn off so that clogging of the gap is restituted, and the contaminated water including the removed attachment is sucked by a suction duct and sent to a collecting tank 30 to get it rid of.

摘要： PROBLEM TO BE SOLVED: To prevent blowholes or large voids from remaining in concrete by placing concrete while it is in fluid form, and applying ultrasonic waves from an ultrasonic oscillator to the fluidized concrete for tamping the concrete. SOLUTION: Into the molding part of formwork 18 having a pair of side forms 10, a bottom plate 12 having a bulkhead on its top surface, and a pair of front and rear side plates 14, concrete is poured and molded, and this molding is cured and hardened to obtain a concrete block. The concrete block in its fluid form is inserted into the molding part of the formwork 18, and the molding part is deepened by lowering the position of the bottom plate 12. Concrete is newly placed on the upper surface of a hardened old concrete block. An ultrasonic oscillator 27 comprising an ultrasonic vibrator and water both stored in a predetermined container is brought into contact with the upper surface of the newly placed concrete. The ultrasonic oscillator 27 is moved horizontally to tamp the concrete.
