摘要： PROBLEM TO BE SOLVED: To provide an improved device for placing a high-fluidity reclamation material (fluidized soil or lighter soil) in water. SOLUTION: A high-fluidity reclamation material force-feeding hose 3 is connected to the upper end of a tremie-shaped placement pipe 1 suspended by a suspending wire 2 and a large-diameter end fitting 4 is mounted at the lower end thereof. The lower end of the placement pipe 1 is extended so that the reclamation material is discharged in a tangent direction near the inner face of the upper half of a cylindrical pipe portion 6 of the end fitting 4 to abruptly weaken the discharge energy of the reclamation material. It is acceptable that a rubber plate 10 with a clinometer 11 is mounted in a discharge port on the side of the end fitting 4 rotatably in the vertical direction or the placement pipe 1 is made flexible with an inner pipe 12 and an outer pipe 13.

摘要： PROBLEM TO BE SOLVED: To forcibly feed a fluidized soil made of soil, cement and water by a concrete pump for a long distance. SOLUTION: A high pressure air feeding device 4 comprising an air compressor and an air compressing cylinder adapted to intensify compressed air from the air compressor for feeding it intermittently into a force feed pipe 3 for the fluidized soil is arranged near the concrete pump 2 adapted to forcibly feed the fluidized soil. An auxiliary air feeding device 5 adapted to fed intermittently the compressed air from the air compressor into the force feed pipe 3 on a downstream part may also be mounted thereon. Feeding the compressed air is done by using intermittent pressure drops by pulsation inside the force feed pipe 3. The fed compressed air pushes aside the fluidized soil for assisting its flow.

摘要： PROBLEM TO BE SOLVED: To provide a method of cleaning contaminated ground which efficiently cleans contaminated soil by efficiently and uniformly distributing soil microorganisms and their nutrient sources into contaminated strata in the ground, thereby enhancing the contaminant material decomposition activity of the soil microorganism. SOLUTION: Pumping wells 2 and sand pits or gravel pits 1 compounded with the soil microorganisms or the nutrient sources for the soil microorganisms are formed at suitable pitches in the ground Y where the contaminated strata exist in the ground and the groundwater is pumped up by the pumping wells 2. The pumped water is supplied to the sand pits or gravel pits 1 to form streams X of the groundwater, by which the soil microorganisms or the nutrient sources for the soil microorganisms are diffused into the contaminated ground Y.

摘要： PROBLEM TO BE SOLVED: To permit easy execution of works even in a narrow place difficult to make access. SOLUTION: A pair of winches 1, 2 are installed on one side of a water area where the works are to be executed, and a pulley device 3 is installed on the other side. A wire for movement 4 extended from the winch 1 is led around the pulley device 3 and mounted on a lightweight earth discharge device 6, while a towing wire 5 extended from the winch 2 is directly attached to the discharge device 6. A float being buoyant up to the surface and sinking is mounted on this discharge device 6. The device 6 is floated at the water surface by the buoyancy of the float and moved, and when towing is made for performing the discharging operation for lightweight earth, water is put in the float so that it is sunk to the water bottom.

摘要： PURPOSE:To make it possible to tamp the whole construction area uniformly by moving a vibration tamping machine horizontally on the ground while controlling moisture content ratio so as to close to the optimum moisture content ratio by means of a forced dry means when there is a part of high moisture content ratio in the execution ground. CONSTITUTION:The vibration of a exciter 3 is transferred to the ground surface through a damper plate 2 while moving a vibration tamping machine 1 by a tractor 5, and a ground upper layer E is tamped. At that time, as for the part having moisture content ratio higher than the optimum moisture content ratio among construction areas, it is tamped while controlling the moisture content ratio so as to close to the optimum moisture content ratio by a dehydrating renovation agent discharged tot he bottom of the plate 2 from a heating element 6 incorporated into the damper plate 2 or from a tank 4. According to the constitution, there is no variation in the moisture content ratio during the time from the controlling of the moisture content ratio to the tamping execution, so that uniform tamping can be carried out allover the execution area.
