摘要
传统单管法旋喷桩径一般在 30 0～ 80 0 mm,桩材强度、桩径、水泥用量等参数变化很不稳定。而采用异型喷头工艺技术 ,单管法旋喷的桩径可有效增大 ,其成桩工效及质量明显提高 。
The rotary shotcrete foundation pile diameter generally is 300～800 mm.The change of parameter of the pile intension,the pile diameter and cement dosage is instability.And after adoption allotype spout,the diameter of monotube rotary shotcrete foundation pile is availably augmented,the work efficiency and quality are evidently advanced,and the cost of construction is debased.
