However, in recent years, some construction units in the construction of pile foundation due to some construction points and quality control is not in place and other reasons caused the construction accident. This paper introduces the various technical aspects of construction techniques, key points of quality control in the construction of pile foundation, pile foundation construction is the most widely used of the castinplace pile construction technology are summarized, in order to accumulate the pile foundation construction experience, to ensure that meet the design requirements of the bearing capacityof pile foundation. In order to ensure the safety of construction of pile foundation of high risebuilding, avoid has important theoretical and practical significance of accidents.
