摘要： PURPOSE:To enable instantaneous measurement of a specific weight by incorporating the apparatus into a part of a conveyance pipe as bypassing circuit to measure a part of a fluid matter flowing through the conveyance pipe after being introduced to a subpipe part. CONSTITUTION:When a fluid matter is conveyed, opening-closing valves 7, 8 and 15 are opened while an opening-closing valve 19 and a valve as pressure withdrawing means 9 are closed. In measurement, the opening-closing valves 7 and 8 are closed to seal up a part of the fluid matter into a subpipe 3 and a vertical part 16. The valve as the pressure withdrawing means 9 is opened so that a liquid pressure is kept at an atmospheric pressure to measure the weight by volume of the fluid matter in a measuring means 11. If the pressure on the liquid is different from that on the supply side, the valve is closed by the pressure withdrawing means 9 while the opening-closing valve is opened and a pressure is adjusted by an internal pressure adjusting means 17 to reach a set pressure of a pressure setting valve 20 and then, the fluid matter in the measuring member 11 is measured. Thereafter, the valves 7 and 8 are opened while the opening-closing valve 15 is closed and the fluid matter in the subpipe part 3 is washed away. The operation is returned to the initial state.

摘要： PROBLEM TO BE SOLVED: To facilitate the regulation of the components of a fluidizing-processed soil by mixing processed soil, water or regulating mud, and removing an excessively large foreign matter from obtained mixture, and after adding a solidifying agent in a sieved mixture, adding water or a regulated muddy water and mixing them. SOLUTION: After processed soil and water or regulating mud are mixed in a kneading vessel 1, a excessively large foreign matter is removed from an obtained mixture through a vibration sieve arranged under the kneading vessel 1. The simultaneous removement of a soil adhering to a shell, etc., is prevented by this sieving. After a solidifying agent is then added into a sieved mixture from a cement silo 5, the water or the regulating muddy water is added in the kneading vessel 4 arranged under the vibration sieve and mixed. A transfer among devices is carried out by utilizing the gravity of the mixture, and an obtained fluidizing processed soil is stored in a storing vessel 8. Thus the fine component regulation of processed soil, regulating muddy water, solidifying material component and weight ratio can be simply carried out.

摘要： PROBLEM TO BE SOLVED: To sample the adjusted muddy water with a uniform specific gravity and particle size distribution by circulating the slurry matter obtained by adding stabilizing liquid or water to the sediment, into which foreign matter such as solidification material, concrete waste, or the like is mixed, in a circulating path so as to remove the foreign matter. SOLUTION: A slurry matter obtained by adding water to a waste soil in which foreign matter is mixed is circulated through a circulating path 10 by a circulating pump 11. In the circulating path 10, a turbulent flow part 15 provided with multiple projected parts on the bottom surface, a restricted path part 16 to partially increase a velocity, a deep part 17 to decrease the velocity, and a wall body 18 installed erectedly at the end part of the deep part 17 are arranged along the circulating direction. Also an adjusted muddy water B is taken into sampling tanks 13a, 13b, and 13c provided at relatively stable parts of flow behind the wall body 18 through sampling pipes 20. Because the adjusted muddy water B is larger in specific gravity as it goes further to the bottom of it, the gravity of the adjusted muddy water to be collected can be adjusted by changing the height of the sampling pipes 20. Thus foreign matter can be removed from the waste soil so as to provide the adjusted muddy water with a specified specific gravity.

摘要： PROBLEM TO BE SOLVED: To improve quality and productivity by applying continuous treatment to treated soil in a specified process to make component adjustment. SOLUTION: Treated soil 42 after eliminating foreign matters 43 by a classifier 1 is discharged in specified quantity to a belt conveyor 7 by a screw conveyor 6 in a hopper 5, and the conveyor 7 measures the weight by a load meter 8 and conveys the treated soil 42 to a mud mixing tank 11. Water in a supply tank 9 fed from a storage tank 16 is fed in specified quantity to the tank 11, and kneaded muddy water is stored in a reserve tank 17 via the storage tank 18, a force-feed pump 19 and a return pipe 34. The density and flow value of the muddy water are measured by a measuring device 32 in a trap 13, and at the time of off-specification, muddy water in the tank 17 is fed to the tank 11, and soil 42 and water are added and kneaded. In the same way, muddy water is continuously manufactured in the tank 11 and mixed with the muddy water, and a solidifying agent is charged from a solidifying agent tank 14. After kneading, kneaded mud is discharged to the storage tank 18, and the density and flow value are measured by the device 32 in the tank 18. In case of being within specification, the mud is placed by the pump 19. Treated soil with requested property can therefore be manufactured efficiently.

摘要： PROBLEM TO BE SOLVED: To easily manufacture requested fluidization treated soil by using redundant soil, generated at the time of filling solidifying material and water while excavating the ground and mixing them with soil in an original position to form a foundation or the like, as solidifying material. SOLUTION: The ratio of fine grain soil is examined in a grain size test of surplus soil generated at a construction site. Water and solidifying material are added to the surplus soil and mixed. In case of the surplus soil being sandy, muddy water and solidifying material are added and mixed. Redundant soil with fluidity used as muddy water is diluted with water and adjusted to specified density, and then subjected to a fluidity test and a water content ratio test and adjusted to have a requested characteristic. The surplus soil and redundant soil are mixed according to a specified mixing ratio and subjected to tests of density, flow value, or the like. In case of obtaining the requested characteristic, a mixing ratio range of the surplus soil and redundant soil is determined. The density of the redundant soil is adjusted to the value less than 1.3 kg/m . Disposal cost is therefore reduced, and a construction period is shortened.
