NEWLY CONSTRUCTED FOUNDATION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive newly constructed foundation structure by which the rigidity of the ground around footing construction is enhanced to improve a supporting force of a footing. SOLUTION: An annular underground wall 13 is buried in the ground 11 around a place where the footing is constructed. The footing 15 is constructed on heads 14b of a plurality of piles 14 driven into the annular underground wall 13 so that front ends 14a may reach a predetermined position 12. In the newly constructed foundation structure 10 which is thus constructed, the underground wall 13 is buried to a depth in a range effective for the horizontal resistance of the plurality of piles 14, and the ground 11 in the underground wall 13 is solidified and improved to the depth in the range effective for the horizontal resistance of the plurality of piles 14. The solidified and improved part is shown by a symbol A. COPYRIGHT: (C)2007,JPO&INPIT
