斜向旋喷搅拌加劲桩技术作为一项基坑支护新技术,与传统的锚杆和土钉相比,它克服了锚杆、土钉在砂土和软弱土层中施工困难的问题,解决了锚杆、土钉锚固力有限问题。此外,它可以取代传统的内支撑结构体系,具有方便土方开挖,缩短工期,节约支护成本等优点。通过对某深基坑工程不同设计方案的对比分析表明,斜向旋喷搅拌加劲桩支护在造价、工期上具明显优势。因此,该项新技术具有很好的推广价值及广阔的应用前景。

Oblique rotary jet mixing anchor pile is a new shoring technique for foundation pit. Compared with the anchor rod and soil nailing, it overcomes the problem of difficult construction in sandy soil and soft soil, and solves the problem of anchor bolt limited. In addition, it can replace the traditional inner supporting struc- ture system. This may facilitate the earth excavation, shorten the construction period, and save the support cost. The different design schemes comparison for a deep foundation pit shows that the new technology in cost, time limit has obvious advantages. Therefore, it has very good popularization value and broad application prospects.
