ABSTRACT:
The present invention relates to a process of setting a concrete pile without noise or vibration which is thereby effective to decrease city noises. A concrete pile is sunk into a leading hole substantially concurrently with the progress of the excavation thereof. After the pile has been sunk through a desired distance, another supporting hole is excavated below the pile. A solidifying material, such as cement milk, mortar, or cement concrete including a cement expansion agent of calcium sulfoaluminate system or lime system, is poured into the supporting hole. The solidifying material is expanded within the supporting hole and permeates into the circumferential wall thereof, which is loosened by the excavation, so as to retighten the wall. Therefore, sufficient supporting force can be obtained.
