Study on Construction Parameters of Cement Deep Mixing Piles

Abstract:

Article Preview

Construction quality is one of the main reasons which lead to the failure of cement deep mixing pile. In order to ensure the construction quality of cement deep mixing pile and control its construction process, the influence of four construction parameters such as slurry conveying capacity, drilling and hoisting speed, agitation shaft rotation speed and remixing times on pile quality are analyzed. At last key reasons to ensure the construction quality of cement deep mixing pile are pointed out. Pile quality and construction efficiency should be considered when construction parameters being optimized. The research results provide reference for construction of cement deep mixing piles in the future.
