摘要： PROBLEM TO BE SOLVED: To provide a construction management system in a ground improvement method, which enables speedy calculating an estimated amount of excavated soil with high reliability.SOLUTION: An inventive construction management system is applied to a ground improvement method in which a screw rod equipped with an agitation blade at its tip is penetrated into the ground, a ground improvement material is injected into the ground, the screw rod is pulled out while the ground improvement material and sediment are agitated/mixed together by rotation of the agitation blade, and the sediment equivalent to the amount of the injected ground improvement material is removed. In the construction management system, a depth, the number of revolutions, penetration speed, and pulling-out speed of the screw rod, and an injection amount of the ground improvement material are detected and monitored. Then, a ratio of the injection amount of the ground improvement material slurry to the ground to be improved is regarded as a ground improvement material mixing ratio, an earth removal factor is set on the basis of a predetermined ground improvement material mixing ratio from a relationship between a preliminarily obtained ground improvement material mixing ratio and earth removal factor, an estimated amount of soil excavated by the screw rod is calculated on the basis of the set earth removal factor and the number of revolutions, and the estimated amount of excavated soil is monitored as a management item.

摘要： PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure structure suppressing liquefaction of the ground with a liquefied layer deposited on a non-liquefied layer or suppressing ground deformation caused by liquefaction without costing a great deal.
SOLUTION: The liquefaction countermeasure structure applied to the ground with the liquefied layer 2 deposited on the non-liquefied layer 1 includes a soil improving body 3 constructed in a position, separated from the non-liquefied layer 1, in the liquefied layer. Since a grounding structure 4 grounded on or set into the non-liquefied layer 1 and allowing the soil improving body 3 to abut on the side face is constructed, a horizontal displacement difference from the soil improving body 3 is reduced even when the non-liquefied layer 1 is horizontally displaced by an earthquake. The shearing strain of a permanent liquefied layer 2A between the non-liquefied layer 1 and the soil improving body 3 is thereby suppressed, and liquefaction or ground deformation caused by liquefaction can be suppressed.
