The rigid-like and large diameter cement-soil mixing pile is a new pile type in cement-soil mixing pile series; its unique scientific and technological achievements have won the praise of many engineering experts and it was popularized and applied in the Pearl River Delta region with most significant outcome of sustainable development of low-carbon goal: low consumption, low noise and no pollution construction. By the examples of pile type and combining with the geological features of the Pearl River Delta region, the paper introduced that in the pile-site, the pile core-pulling strength of 95% Φ1000~1200 mm cement mixing piles reached to qu (28d)≥1.5~2.0 MPa in water content of 70%~ 80% (due to consolidation) of sludge formation, and Φ1000 cementsoil mixing pile penetrated through N≥38 hit rough (gravel) sand formation.
