摘要： PROBLEM TO BE SOLVED: To provide granular improved soil with properties equivalent to those of grit soil, with respect to a method for manufacturing the granular improved soil and the granular improved soil.
SOLUTION: The method for manufacturing the granular improved soil 10 first throws construction generation soil 14 and calcined lime 17 from a silo 16 for limestone into a water content adjustment device 12 to adjust the water content of the construction generation soil 14. The water content is adjusted in the range of more than 20% and less than 35%. Next, in a cement addition step 42, the predetermined amount of cement 22 is added from a silo for cement to the construction generation soil 14 adjusted with the water content in step of conveying by a belt conveyor 18. Next, in a mixing step 44, the construction generation soil 14 is crushed and mixed with cement 22. The mixing step 44 is carried out using crushing-mixing device 24 in which the construction generation soil 14 is thrown from the top to a rotated chain 28 and crashed slab 30 to cause it to collide with the chain 28 and the crashed slab 30 at a lower stage in turn to crush it. Simultaneously, it is mixed with cement. Finally, in a curing step 46, the crushed and mixed granular improved soil 34 is conveyed to a curing place by the belt conveyor 32, and cured for 1 to 7 days.

摘要： PROBLEM TO BE SOLVED: To provide a method of constructing a composite body of piles of a pile foundation or settling preventive piles for use in a soil improving direct foundation, and soil improving bodies, by completely combining the former with the latter, and to provide an apparatus for constructing the same.
SOLUTION: The method is composed of the following stages. In the first stage, the piles are driven into the ground to a necessary depth before or in parallel with the construction of the soil improving bodies. In the second stage, a deep stratum mixing machine which has at least two shafts is employed. One of the agitating/mixing shafts is replaced by an agitating/mixing cylindrical shaft which has a hollow cylindrical shape having an inner diameter larger than the external diameter of the pile, and allows in-situ excavated soil and injected cement milk to flow therein to carry out agitating/mixing work. Alternatively a modified deep stratum mixing machine originally provided with the agitating/mixing cylindrical shaft is employed. Then the agitating/mixing cylindrical shaft is penetrated into the ground along the pile and concentrically with the pile to a scheduled depth of soil improvement, then the injected cement milk and the in-situ soil are agitated and mixed to improve the ground around the pile, and at the same time the improved ground is partially overlaid with the soil improved pile constructed by the other agitating/mixing shaft.

摘要： PROBLEM TO BE SOLVED: To provide a method for lowering the underground water level of an aquifer in the excavated ground after forming an artificial low permeable layer below the excavation bottom when no clear impervious layer exists below the excavation bottom in the case of carrying out dry work by lowering the underground water level in the excavated ground surrounded by an impervious wall, below the excavation depth.
SOLUTION: At least two filling/pumping wells are installed with a specific space in the ground surrounded by the impervious wall, down to the depth reaching the formed position of the low permeable layer below the excavation bottom. One of the two filling/pumping wells is used as a filling well, and the other as a pumping well to form the low permeable layer in the ground surrounded by the impervious wall. After completing the formation of the low permeable layer, the filling/pumping wells are changed over to pumping wells functioning only in the aquifer ground above the low permeable layer, and underground water above the low permeable layer is pumped to lower the water level.
