  • Patent number: 10767333
    Abstract: The present invention enables easy construction of a foundation pile having a rigid structure even at a site where a pile produced in a factory cannot be brought in. The tube 1 having a forming material filling port 1a at a top end and a closed bottom 1b at a bottom end is set in a suspended state, and foundation pile forming material 4 is filled from the forming material filling port 1a into the tube 1 in the suspended state. A composite foundation pile 5 in which the tube 1 and the filled forming material 4 are integrated is formed, and the composite foundation pile 5 is driven into the ground 13 or inserted into a borehole 12 formed on the ground 13.

  • Patent number: 7469439
    Abstract: A floor slab bridge structure is capable of enhancing the strength with which bridge girders and concrete bridge piers are rigidly joined so as to effectively suppress expansion and contraction, deflection, and distortion of the bridge girders, and to synergistically enhance the strength of connection concrete itself against the expansion and contraction, distortion, etc., to thereby be effective to prevent collapse of a bridge due to a large earthquake. Slab concrete is hammer-set between sides of respective bridge girders, which are spaced apart in a bridge width direction, along a length direction of the bridge girders. Connection concrete, in which bridge girder portions supported on bridge bottom surfaces of concrete bridge piers supporting the bridge girders are embedded, is additionally deposited on the bridge bottom surfaces to form a floor slab bridge structure constituting a rigid joining structure.

  • Patent number: 4351252
    Abstract: An apparatus for treating a water solution of a waste material containing a salt with smelt-water explosion characteristics comprises an open-bottomed incinerator and a gas-liquid separator disposed beneath the incinerator in fluid-flow communication therewith. The waste solution is sprayed into the incinerator and heated therein so that the salt in the solution is fused, water vaporized and organic components of the solution burned. The combustion gases and water vapor flow downwardly into the separator, while the fused salt forms a deposit on the inner surface of the incinerator and flows downwardly into the separator. At the junction between the incinerator and separator, cooling water is fed to the fused salt so that the deposit of salt is solidified and cracked into separate masses which fall together with the cooling water onto an inclined baffle member disposed in the separator and roll downwardly on the baffle member.
