摘　　要：论文结合金象新天地商业街项目工程实例,介绍了长螺旋钻孔压灌桩的施工工艺。长螺旋钻孔压灌桩作为桩基础处理的一种,因其对环境影响小,直径小、入土深,可更好地发挥桩端土的作用;且长螺旋钻孔压灌桩的施工速度快、噪音小,成孔率高、对土层扰动较小,作业时不需要进行泥浆护壁,从而也避免了噪音扰民和环境污染等。由于长螺旋钻孔压灌桩技术多种突出的优点,在地质松软、承载力差地基工程中广泛采用,对同类型工程具有重要的借鉴意义。Combined with the project of Jinxiang Xintiandi Commercial Street,this paper introduces the construction technology of long spiral bored pressure grouting pile.As a type of pile foundation treatment,the long spiral drilling pressure grouting pile has a small impact on the environment,a small diameter,and a deep penetration into the soil,which can better play the role of the pile end soil;Moreover,the construction speed of the long spiral drilling pressure grouting pile is fast,the noise is low,the hole completion rate is high,and the disturbance to the soil layer is small.There is no need for mud wall protection during operation,which also avoids noise disturbance and environmental pollution.Due to the various outstanding advantages of the long spiral drilling pressure grouting pile technology,it is widely used in geological soft and poor bearing capacity foundation engineering,and has important reference significance for similar projects.
