Abstract

PURPOSE: To make cheap a foundation pile and to make it possible to constitute it with high degree of accuracy and efficiently by excavating succeedingly to excavate a hole concentrically to an excavated hole from which soil is antecedently moved and, at the same time, jetting improvement materials to later excavated soil to mix and stir, and forming a construction pile such as a soil cement column, etc..
CONSTITUTION: An excavated hole having the same diameter as that of an excavated hole 2 or larger diameter is excavated antecedently in a specific depth to the excavated hole 2 of a construction pile having a specific diameter, etc.. Soil from antecedent excavation is antecedently moved as a designed soil moving volume, and excavated hole having a set diameter forming a specific soil cement pile 19 by a rod through a guide 16 of a mouth pipe 3 so that it is concentrically the excavated hole 2 is excavated succeedingly to excavate a hole concentrically to the excavated hole 2 from which soil is antecedently moved. Improvement materials such as cement milk, etc. jetted from an excavated rod to excavated soil of later excavation are uniformly mixed and stirred by relative reverse rotation or up and down motion control of a mixing and stirring wing 10 of up and down, etc., and the construction pile such as the soil cement column 19, etc. is formed.
