深厚砂卵石地层中砂浆-砼咬合桩的应用

The application of mortar-concrete secant pile in deep and thick sandy pebble soil

本文介绍砂浆-钢筋砼咬合桩的施工工艺,并对其特点以及其关键技术做浅要分析,实践表明:砂浆-砼咬合桩在深厚卵石层中可满足挡土防渗要求,砂浆桩更易进行硬切割法施工,桩身完整性较好,砂浆-砼咬合桩支护形式具有良好的施工效果及经济效益。

This paper introduces the construction technology of mortar reinforced concrete interlocking pile,and analyzes its characteristics and key technologies.Practice shows that mortar reinforced concrete interlocking pile can meet the requirements of soil retaining and Seepage control in deep and thick sandy pebble soil,mortar pile is easier to be constructed by hard cutting method.The integrity of pile body is relatively good,and the support form of mortar reinforced concrete interlocking pile has good construction effect and economic benefits.
