    Abstract: PROBLEM TO BE SOLVED: To provide an enlarged-diameter caisson foundation structure which is excellent in construction of a caisson foundation, and economical.
    SOLUTION: In construction of the caisson foundation, a caisson main body 11 having a circular cross section is driven into the ground until a front end 11b is embedded in a support layer 8, and a head portion 11a of the main body bears a bridge pier 10. On the periphery of the caisson main body 11, a cylindrical steel sheet pile wall 12a is driven into the ground 7 until it reaches a predetermined depth. Next, earth in a gap between the caisson main body 11 and the steel sheet pile wall 12 is improved by high-pressure jet mixing or the like to form a hardened layer 13, and the caisson main body 11, the steel sheet pile wall 12a, and the hardened layer 13 are unitedly connected together, to thereby form an enlarged-diameter caisson 16.

    Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive newly-constructed foundation structure which can surely prevent wastewater from percolating into a load-bearing layer, and which can enhance the whole earthquake-resistant performance.
    SOLUTION: In a newly constructed bridge pier 10, a newly constructed footing 11 is borne on heads 12b of a plurality of newly constructed piles 12 whose leading ends 12a are sequentially driven in from a burying soil layer 5 as an uppermost layer to a waste layer 6, an impervious layer 7 and the load bearing layer 8 as a lowermost layer. In the foundation structure, a square tube-shaped steel sheet pile wall 13 is provided in the ground at least in the upper section of the impervious layer 7 from the burying soil layer 5 around the footing 11, and cement-mixed soil 14 is infilled into a space wherein at least waste 6' of the waste layer 6 in the wall 13 is completely excavated.

    Abstract: PROBLEM TO BE SOLVED: To spray and mix coagulant into discharged muddy water during a time when pumped up and discharged to a ground surface to establish the condition that the muddy water, when discharged to the ground surface, is mixed with the coagulant in an approximately homogeneous manner in ground improving technique for a high pressure injection stirring system. SOLUTION: In the ground improving technique, a pouring shaft 1 which injects liquid solidifying agent via a nozzle at high pressure for mixture and stirring while scraping surrounding sediment away, has a coagulant spray nozzle separately provided at a position somewhat upper than the nozzle. The coagulant having a volume corresponding to the amount of the discharged muddy water to be generated with the construction of improving work is sprayed and supplied via the nozzle to a muddy water stream being pumped up along the pouring shaft 1.

    Abstract: PROBLEM TO BE SOLVED: To surely and simply conduct driving to a hard portion at the ground side by contriving auxiliary equipment for penetration and eliminating the possibility of inclining or overturning by a reaction given to a moving body at the ground side.
    SOLUTION: A driving pipe 3, a draining member 4 made of plastic which is inserted to the driving pipe 3 installed on the moving body 1 and driving equipment 5 are provided on the moving body 1. In this soil improvement method, the draining member 4 is installed in the vertical direction of the ground by pulling out the driving pipe 3 after penetrating the driving pipe 3 in the vertical direction into the ground by the driving equipment 5. Some of features of the method and equipment are that at least a base member 7 cantilevered in a pipe diameter direction and connected to the driving pipe 3 in a detachable manner and a weight member 8 movable along the upper and lower directions of the pipe are provided, and each draining member can be penetrated into a hard portion m1 of the ground by a collision load caused by hitting the base member 7 by the free falling of the weight member 8 from a predetermined height.
