PURPOSE:To exactly prevent the degradation of pile wall by a method in which bearing layer is improved to form gel blocks, the gel block is pulled up with an earth auger, a stabilizer solution is injected, and the earth auger is again inserted and pit wall is stabilized to form a pile. CONSTITUTION:An earth auger 1 is turned to improve the bearing layer 18 and pulled up with a gel block 10. A bentonite solution 11 is injected from the end of the shaft 2 of the auger 1, the auger 1 is again inserted into the pit, and the wall of the pit 8 is treated by a trowel. A reinforcing bar cage 13 is then set in the pit 8, and a tremie tube 14 is penetrated to place ready- mixed concrete 15. A good shape of concrete pile can thus be formed, and slime can also be effectively removed.
