PROBLEM TO BE SOLVED: To provide a polluted soil detoxification system reduced in installation cost and running cost of a cleaning unit, in the case that decompression reduction heat decomposition dechlorination treatment is carried out by installing a decompression reduction heat decomposition apparatus is housed in the inside of a building. SOLUTION: The polluted soil detoxification system is a system using a decompression reduction heat decomposition apparatus 24 installed in the inside of a building 115 and includes a leakage detection means for detecting occurrence of the hazardous state of pollutant leakage, a ventilation unit 111 for discharging a gas outside of the building 115, a cleaning unit 112 for cleaning the gas containing polluting substances and discharging the gas outside of the building 115, and a switching damper 113 for switching the ventilation unit 111 and the cleaning unit 112 in a manner that the gas in the building 115 is discharged via the ventilation unit 111 while detouring the cleaning unit 112 in the case no hazardous state of leakage occurs and the gas in the building 115 is discharged via the ventilation unit 111 and the cleaning unit 112 in the case the hazardous state of leakage occurs.

PROBLEM TO BE SOLVED: To provide a material management system, a material management method, and a material management program which can manage materials with greater precision. SOLUTION: The capacity of a transfer vehicle to carry a cement system material is calculated by a calculation part 44 for every transfer vehicle which is used for transferring the cement system material to the field where pouring is performed. Then a rectangular block of the size corresponding with the carrying capacity calculated for every transfer vehicle is derived as a management block which is a management unit of the cement system material, and information on characteristics indicating the characteristics of the cement system material is obtained for every management block which has been derived. Then information on a pouring position which indicates the actual pouring position of the cement system material by the transfer vehicle is detected for every transfer vehicle. The obtained information on characteristics and the detected information on the pouring position are linked to each other for every corresponding management block, and are stored in the secondary memory unit of a server device 20 provided in a construction office.

Abstract:
PROBLEM TO BE SOLVED: To provide a solid collection system of a shield machine capable of dispensing with an independent solid collection carrier when collecting solid matters in a pit in excavation over a long distance to achieve a satisfactory construction property and collecting the solid matters on the way to initial excavation. SOLUTION: This solid collection system of the shield machine cuts out the natural ground in an excavation path in a solid state by a cutter head and excavate it, transports the cut-out and excavated solid matters 32 collected up to a primary pretreating machine 30 in the pit through mud discharging pipes 24, 26 and 28 together with slurry in a chamber 12 by a mud discharging pump 22, and take the solid matters 32 out of the mud discharging pipe 28 and collect them by the primary pretreating machine 30. The primary pretreating machine 30 is installed on the following carrier 34 connected with the shield machine, and the mud discharging pipe 26 between the first mud discharging pump 22 and a section close to the primary pretreating machine 30 is formed of a pressure-loss increasing special pipe having a resistance part for increasing the resistance of the mud discharging pipe itself on an internal wall face to keep working face water pressure.

Abstract:
PROBLEM TO BE SOLVED: To provide a liquefaction preventing method, a liquefaction preventive ground, and a building base part structure using the weight of a building itself to constrain the ground while improving ground constraining force by shutting a ground portion right under the building off a peripheral ground and applying a weight to the ground portion. SOLUTION: The ground liquefaction preventing method comprises a step of forming an underground peripheral wall 2 encircling a building in a ground where the existing building is installed, and a step of installing a counterweight 8 on the ground portion in the underground peripheral wall 2. The underground peripheral wall 2 is arranged distant from the outer peripheral edge of the building in the horizontal direction, and the underground 2 is separated from a base part 6 of the building so that the load of the building operates on the ground portion in the underground peripheral wall 2 to tighten soil in the ground portion. The weight of the counterweight 8 is set so that the tightening force is great enough to prevent the liquefaction of the ground. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To obtain a satisfactory sideways flow preventive effect by effectively reinforcing the banking support ground by improving soil having a low improvement rate. SOLUTION: A soil improvement body 3 supporting at least the peripheral edge part of a banking 1 is constructed in the banking support ground 2, a tension member 5 is disposed along the direction of causing a sideways flow in a base layer part of the banking or a surface layer part of the banking support ground, one end of the tension member is fixed to the upside of the soil improvement body, and the other end of the tension member is fixed to the upside of the other soil improvement body. A core material 6 made of steel material is integrally fixed to the upside of the soil improvement body, the tension member is connected to the upside thereof, and the tension member is fixed to the soil improvement body through the core material. The middle part of the tension member is supported by the other improvement body (a soil improvement pile 7). A batter pile formed of a soil improvement body is provided on the side of the outside or inside of the soil improvement body supporting the peripheral edge of the banking, and the upside of the soil improvement body is supported by the batter pile.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing volatile substances which can remove volatile substances more efficiently by volatilizing the volatile substances from solid substances with the volatile substances mixed. SOLUTION: Soil contaminated with volatile organic compounds and the like is mixed uniformly with inorganic compounds that undergo exothermic reaction with water while sufficiently grain-refining them with the use of a grain refining and mixing unit 100. Subsequently, the mixture is added to an air contact treatment unit 200. In an air contact treatment part 210 of the air contact treatment unit 200, volatile organic compounds and the like are volatilized and purified from contaminated soil within a cylindrical part 211. At this time, a predetermined amount of at least a portion of the mixture is lifted via a projecting part 212 with the rotation of the cylindrical part 211 and then caused to fall. Thus, unlike a conventional technology involving simple agitation, not only the surface but also the inside of the mixture can be caused to come into contact with air more efficiently and thus purification efficiency of contaminated soil can be elevated.
