A study on filling and ocmpacting of unbounded sand by vibration on EPC

摘要

The essential rule of filling and compacting into horizontal hole in pipe patern has bene researched.using the method of continuous testing by pressosensor and instancing pipe pattern on EPC.By analysizing tested results of the unbounded sand compactivities,its dependence on vibration parameters,pattern structures has been aquired.The arrived conclusion is in acford with practical production by validatation,it is of instruction to filling process of unbounded sand to horizontal hole in pipe pattern on EPC.
