ABSTRACT

Method of treating weak ground base with cement soil piles are wide application in the treatment

df foundation for the works airports, seaports, highways...With each construction, the depth pile soil

cement will differ so will the use of drill piles soil cement different. Therefore, the research to determine

the effect of depth pile to pressure and flow motor driven drilling rdd of drilling machine soil cement

makes calculations, select drill piles soil cement are suitable and highest efficiency.

Keywords: Pile soil cement, depth pile, pressure and flow motor.
