摘要
由于事先城市规划的局限性,没有给港口仓储服务预留足够的空间,填海造地成为了提升一个城市的仓储能力的方法,填海区一般采用抛石法,该填海区上部再修建其他建筑物时,尤其桩基础,抛石会使灌注桩施工极其困难,境内往往采用冲击钻成孔方式施工,此方法施工效率低,扩孔严重,现介绍一种带通钻孔法桩基施工技术,以解决灌注桩施工困难的难题。
Due to the unreasonable urban planning in advance and the lack of sufficient space reserved for port storage services,land reclamation has become a method to improve the storage capacity of a city.The riprap method is generally used in the reclamation area.When other buildings are built on the upper part of the reclamation area,especially the pile foundation,riprap will make the construction of cast-in-place pile extremely difficult,Percussion drilling is often used for construction in China.This method has low construction efficiency and serious hole expansion.This paper introduces a band-pass drilling pile foundation construction technology to solve the difficult problem of cast-in-place pile construction.
