石灰処理土を用いたソイルモルタルの製造方法及びそれを用いた盛土工法

Japanese Patent JP4109376

B2

PROBLEM TO BE SOLVED: To provide a method for preparing an excellent fluidization-treated soil having good filling properties without leaving voids and totally well balanced with respect to properties such as fluidity, resistance to material segregation and strength, and a banking method using the same in the civil engineering and construction works. SOLUTION: A clod 1 is added to and mixed with 10-300 kg, based on 1 m3 clod, quicklime or soil conditioner 2 whose major component is quicklime, and the clod and the soil conditioner are cracked to form a lime-conditioned soil 5. Water 6 and a hydraulic solidification material 7 is added to and mixed with the resulting lime- conditioned soil 5 to prepare a soil mortar 9. Not less than 50 vol.% lime-conditioned soil is incorporated into a fluidization-treated soil, and the resulting mixture is subjected to classification treatment according to circumstances. A banking structure is executed with the use of the fluidization-treated soil. In this instance, the fluidization soil is transported to the execution site by equipment having a pump as the transportation means. According to circumstances, shoot-stamping is used in execution of banking. The utility of generated residual soil is increased and excellent workability in construction is obtained.
