发明名称 Pneumatic grout removal method for forming foundation structures
摘要 A practical method of forming foundation structures for buildings or the like is provided which allows economical and convenient formation of foundation piles and pile caps. In the preferred method hereof, an auger is drilled to a desired depth in the soil whereupon grout is pumped through the hollow shaft of the auger while the auger is removed to form a pile having an upper surface generally even with the initial grade level. A grout pump then removes grout from the pile down to a lower level generally slightly above the desired base level of a pile cap. After the grout hardens, the soil in the vicinity of the pile is removed to a level generally even with the upper surface of the pile whereupon a pile cap is poured onto the pile for at least partial support thereby.
