Abstract

PURPOSE: To reduce moisture content in the periphery, curing a pile in a brief period of time and increase the performance as a bearing pile by driving QCB (inflation acceleration hard solid grains) in a pile shape, further with steel construction material, etc. inserted.
CONSTITUTION: The casing (a) is caused to penetrate rotating to a prearranged depth under the ground which needs to be solidified. Then a hopper (b) is removed from the casing (a) and displaced. Then prefabricated iron reinforcement bar (c) is inserted. The hopper (b) is again fitted to the casing (a) and QCB (inflation acceleration solid grains), a soil stabilizer (d) is charged. Compressed air is injected into the casing and QCB (d) is transmitted by pessure. Following this procedure, the casing (a) is reversed and pulled up. Thus QCB (d) absorbs moisture around the pores, inflating and consequently promotes a consobidation in a horizontal direction.
