浅析三轴搅拌桩设备在九圩港提水泵站防渗墙中的应用

本文通过三轴搅拌桩设备在九圩港提水泵站防渗墙中的应用,介绍了ZKD65-3B型三轴深层搅拌桩的成墙原理、施工工艺、防渗墙技术等,并通过探坑检测、钻芯检测技术对墙体进行检测,结果表明:墙体搅拌均匀,搭接连续、平顺,水泥浆液与土体胶结较好,水泥搅拌桩桩身完整性、均匀性良好,桩身有效强度满足设计要求。三轴深层搅拌桩具有搅拌叶片多、动力大、施工速度快、操作简捷等优点,适用于不同地质条件的深层搅拌桩防(截)渗墙施工和提高软基承载力加固处理。

Initial analysis on the application of three axis mixing pile equipment in the impervious wall construction of Jiuweigang pumping station

Through the application of three axial mixing pile equipment in impervious wall construction of Jiuweigang pumping station,the wall forming principle,construction technology and impervious wall technology of ZKD65-3B type three axial deep mixing pile is introduced. The wall is detected by the technology of pitting detection and drilling core detection. The results show that:the wall is smooth and mixed well,the body integrity and uniformity of cement mixing pile is good,pile strength could meet the design requirements. The three axial deep mixing piles have the advantages of enough mixing blade,big power,fast construction speed and simple operation. The three axial deep mixing piles could be used in different geological conditions of deep mixing pile impervious wall construction and improve the bearing capacity of soft soil foundation reinforcement.
