摘要: <正>结合通启高速公路"TQ-02标段挤密碎石桩的施工,探讨了碎石桩的施工工艺,分析了试验段碎石桩的施工方案及检测结果。结果表明:采用桩管在提升过程中不留振的施工方案,其桩长、桩径及密实度更均匀,施工更快捷方便。

Abstract: The construction techniques of stone piles were discussed. The compaction scheme and inspection result of stone piles on experimental section were presented with the applica- tion of compacted stone piles on TQ-02 contract section in Tong-Qi highway. The results indicated that when the pile tube was not been left to vibrate during lifting, the compaction scheme of stone piles would make the length, diameter and compactness of the pile more uni- form, and the construction more convenient.
