| Abstract: | Bored pile with partially expanding diameter is a new type of pile. When drilling a constant hole, at particular depth where certain type of soil layer suitable for extruding exists, enlarged diameter part may be reamed to form several enlarged part along the concrete pile so as to improve bearing capacity of the pile. This method may shorten construction duration, save concrete, secure quality, being cost effective as well. |
