Construction Technology of Rotary Excavation of Bored Pile in Municipal Road and Bridge Engineering
In order to solve the problems such as the influence of pile foundation construction defects on the stable operation of municipal road and bridge engineering,a kind of construction technology of rotary bored pile is designed.The steel shield of the bored pile was buried,the verticality of the hole was con-trolled by the steel shield,the steel cage was made and hoisted to the hole position.The conduit method was adopted,and the conduit was selected according to the pile diameter and installed in the middle position of the drill hole,and the concrete was poured after confirmation.The application of this technology shows that most of the cast-in-place piles are Class I piles,which can meet the quality requirements of pile construc-tion.
