Abstract

PURPOSE: To perform sufficient compaction of the whole ground by driving a number of piles by use of a mixture of quick lime having specified burning temperature and grain size, a water permeable material, water granulation, and plaster.
CONSTITUTION: Limestone is burned at 1200-1500°C to form a hard burnt quick lime having a grain size of 5mm or more. This quick lime is mixed with a water permeable material such as sand and crushed stone, material water granulation, and plaster to form a foundation improving material. A pile driver 1 is advanced into the ground, the improving material is discharged into a casing 2 from a side hopper 5, and this is pulled out to build a pile 7 in the ground. A number of piles 7 are similarly driven at desired intervals, and the earth is charged in the hole of the pile head part to prevent the float. The hydration reaction of the quick lime is gradually proceeded to sufficiently expand the quick lime. Thus, the sufficient compaction of the whole body is economically performed, and the ground can be improved into a highly rigid ground.
