| Abstract: | Based on soil extruding effect of static pressure piles, characters of pile-soil surface when pipe-pulling and grouting and interaction with pile body, authors conclude bushing pile-forming principles. They also study the bushing grouting new pile-shape technology and the bushing pile head technology, point the development direction of the bushing pile-forming method, and state a invention patent, self-run expander(pile head). |
