粉喷桩质量监理控制要点

Essentials in Quality Supervision of Dry Jet Mixing Pile Construction

粉喷桩是目前软基处理常用的处理方法,广泛应用于公路工程。由于施工具有即时性、隐蔽性,因此粉喷桩施工质量监理控制显得尤为突出。文章结合马鞍山至芜湖高速公路粉喷桩处理软基施工监理实践,提出有针对性的粉喷桩施工质量控制措施,取得了良好的处理效果。

Dry jet mixing pile that is commonly used to treat weak ground foundation finds wide application in road engineering and the instantaneity and invisibility of its construction makes supervision especially important. Combining the supervision practice in dry jet mixing construction of weak ground beneath Expressway Ma＇anshan-Wuhu, this paper presents the targeted measures adopted for quality control that have achieved sound treatment effect.
