某深基坑支护高压旋喷桩的工艺性试桩分析

Analysis of Technical Test Piles of High-pressure Rotary Jetting Piles Supported in a Deep Foundation Pit

通过高压旋喷桩工艺性试桩实例,分析影响成桩质量的因素,并采取相应的改进措施,通过试桩取芯检验,最终取得成桩效果良好的最佳施工技术参数,为后续大规模施工提供依据。给类似地质条件的工程提供参考。

Through the example of a high-pressure rotary jet pile technical test pile,the factors affecting the quality of pile formation are analyzed,and corresponding improvement measures are taken.Through the core test of the test pile,the best construction technical parameters with good pile formation results are finally obtained,which is the subsequent large-scale provide basis for construction.Provide reference for projects with similar geological conditions.
