摘要
挤扩支盘桩是一种新桩型,它在直杆支承桩的基础上,根据不同土层可以挤扩多节支盘,可大大提高桩的承载能力,达到工期短、质量优、节省混凝土和节约投资的目的。
Bored pile with partially expanding diameter is a new type of pile.When drilling a constant diameter hole,at particular depth where certain type of soil layer suitable for extruding exists,enlarged diameter part may be reamed to form several enlarged part along the concrete pile so as to improve bearing capacity of the pile.This method may shorten construction duration,save concrete,secure quality,being cost effective as well.
