Analysis of Slurry Ratio of Rotary Digging Pile in Deep Sand Layer

Abstract Slurry ratio is a crucial link in the construction of bored pile, which directly determines quality pile. In order to determine key performance parameters slurry required form piles deep sand layer, relying on Huizhou north station engineering, an orthogonal test proportioning was designed and carried out, SPSS statistical analysis software used carry out bivariate correlation multivariate stepwise results, combined with index regression equation using MATLAB optimization processing, optimal mix verify, research results show that: screening value, calculation value not different. Conclusion: The that bentonite CMC have significant influence indexes, while Na 2 CO 3 PHP can adjust meet use standard; 148 g bentonite, 5.2 g, 3.5 0.05 g; treatment, feasible reasonable, class I pile proportion more than 98% actual engineering requirements.
