高压旋喷硫铝酸盐水泥浆液处理桩缺陷施工技术研究

Study on the Construction for Pile Defect of High Pressure Jet Grouting with Sulfur-aluminate Cement Slurry

根据合景天峻广场二期项目桩基工程,对高压旋喷硫铝酸盐水泥浆液处理桩缺陷的施工全过程进行了阐述。通过对高压清水旋喷切割、清洗桩底沉渣及高压喷射低碱度硫铝酸盐水泥浆液等技术的研究,达到处理桩底沉渣及加固补强的目的。

According to the pile foundation project of the phase II of Hejing Tianjun Square,the whole process of the construction of high pressure jet grouting with sulfur-aluminate cement slurry to deal with pile defect is expounded. Through the study of the process of high pressure clean water jet cutting,cleaning the bottom sediment and high-pressure jet grouting of low alkalinity sulfur-aluminate cement slurry,the purpose of the disposal of bottom sediment and reinforcing of pile bottom is achieved.
