摘要： PURPOSE:To easily build a large depth shaft by providing a rough gravel taking-in mechanism in a soil discharging pipe utilizing a hollow part of a center shaft of a shield machine, assembling trapezoidal segments formed by equally dividing a circular ring from a starting shaft and giving reaction to the segment to excavate downward with fresh water excavation. CONSTITUTION:A shield machine 1 is held by machine holding mechanisms 7, 9, 10 of a starting shaft 5 to ensure vertical accuracy and initial excavation reaction through reaction mechanisms 4, 6. Next, trapezoidal segments 2 formed by dividing equally a circular ring from a position of the starting shaft 5 are assembled to give reaction to the segments 2 and continuously excavate vertically downward by fresh water excavation. Then when a soil discharging pipe is choked with rough gravel, the rough gravel is discharged to the rear side of a partition wall 11 by a rough gravel taking-in mechanism provided in a hollow part of a center shaft 13. At the step of excavation up to a predetermined depth, a cutter spoke 14 is pulled up and a bottom plate concrete 16 having a face plate 15 as a reinforcement is built in a pressure chamber 12.

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.
