Construction Technology of Concrete Pouring for Inclined Bored Piles with Cast-in-place Piles
Addressing the challenges in concrete pouring for inclined bored piles,where the axis of the hole does not align with the direction of free fall,leading to issues such as the pouring tremie getting stuck on the reinforcement cage,the tendency of concrete aggregates to accumulate towards the inclined direction of the pile,and connection issues between the discharge outlet and the tremie,which can compromise the quality of concrete pouring and the construction process.Based on the inclined bored pile project of a large wharf in Wenzhou,this paper delves into the root causes of potential quality accidents arising from these issues.It comprehensively outlines measures to eliminate the hidden dangers of these quality accidents,clarifies specific practices and control points for preventing quality accidents,and provides valuable insights for similar engineering projects.
