abstract: mechanical bored piles in road and bridge

construction application is extremely widespread. while in road and bridge mechanical construction of bored piles, concrete role is there is nothing comparable to this, its construction technology is the key of the construction

quality of pile foundation in road and bridge. in this paper, the mechanical drill hole filling pile construction in road and bridge in several common quality defect of concrete are analyzed, and the corresponding concrete construction

technology of preventing and controlling are discussed and research. mechanical bored pile is the biggest advantages with a strong ability to adapt, and its equipment is simple,
