Construction Technology of Rigid-Flexible Composite Piles for Reinforced Thick Overburden and Deep-Buried Soft Soil

Abstract:

By adopting the conventional pile foundation to treat the area of thick overburden on soft soil, the reinforcing effect can’t meet the use requirement: by adopting the bulk material pile, the lower pile body strength can’t be ensured, and by adopting the cemented soil mixing pile for reinforcing, the pile is difficult to form and the reinforcing depth can’t meet the requirement. This paper aims to overcome the defects of the conventional construction method by adopting different materials to treat, namely, the concrete rigid pile is adopted for reinforcing the soft soil layer with poor soil body quality and the cement mortar flexible pile is adopted for reinforcing the overburden with excellent soil body quality, therefore not only the reinforcing effect is ensured, but also the construction cost is saved.
