| 摘 要： | 在施工较硬土层时，长螺旋搅拌桩新工艺的优势尤为明显。北京金马工业区污水处理工程基坑支护时采用了长螺旋搅拌桩中插入钢管桩与复合土钉墙相结合的支护形式，既满足了支挡的要求又兼具挡水的功效，节约了投资。实践证明这是一种既安全可靠又经济实用的方法。

| Abstract: | The patent technology of the long spiral mixing pile is one of the emerging construction technologies. It can be used in the foundation pile treatment, foundation pit supporting project and the waterproof curtain, especially in the construction in hard stratum. The combined support technology of long spiral mixing pile inserted steel pipe and composite soil nail was used in a sewage treatment project in Beijing, it not only met the requirement of supporting and waterproof, but also reduced the cost. The practice shows that the technology is safe, reliable, economical and useful. |
