高压旋喷桩止水帷幕和土钉喷锚相结合在深基坑工程中的应用

Application of High-pressure Spiral Pile Waterproof Curtain and Soil-nail Sprayed Anchor in Deep Foundation Pit Support

介绍了在地下水位较高、地基土层为粉土或砂土的情况下,邻接建筑地下工程如何将高压旋喷桩止水帷幕、井点降水、微型桩+预应力土钉支护技术综合使用的典型经验。

Under the condition of high water level and sand or silt as foundation soil,the typical experiences of multiple support technologies for underground projects of adjacent buildings are introduced,including high-pressure spiral pile waterproof curtain,precipitation,micro pile and prestressed soil-nailing support.
