Abstract

Abstract

A new type of long spiral mixing jet grouting pile is introduces which is mainly used for pit waterproof curtain and soil reinforcement.This paper summarized the relationship of pile diameter with the soil and construction parameters.The experimental research results not only provides guidance on construction parameters,but also suggests constructing the long spiral mixing jet grouting pile first then constructing the reinforced concrete revetment pile.This article provides an important reference for the foundation pit support and groundwater control design.
