Hole and pour into one as a kind of basic form has a good adaptability with it, the cost is moderate, the characteristic that construction is simple and convenient is widely applied to the highway bridge and other project fields. Because it puts the adaptability of various geological conditions, simple apparatus easy to use of construction into it is not very big, so is widely used in all kinds of houses and civil buildings. The construction of pouring into one is carried on under water mostly to hole, its course of construction is unable to observe, later cant have gone on either it excavate it confirm. Any link while constructing goes wrong, will all influence quality and progress of the whole project directly, even cause the enormous economic losses and bad social influence to investor. Must prevent and cure in the course of holing and the concrete under water pour into the construction quality problem presented in the course frequently, the guaranteeing the quality, protecting amount finishes the pile construction task. But take place at the time of various defective phenomena in practice, this text holes reason and punishment for pouring into a defect appearing while constructing are made Concision analyze. It develops a new method to deal with weak foundation in recent years
