提高非开挖穿孔锤适应能力的研究

The Research of Enhancing Adapting Capability of Trenchless Grundomat Hammer

通过对穿孔锤工作原理的分析，提出在过硬土层采用高压水射流，在软弱土层（含水量大土层）中使用粉喷技术的措施来提高穿孔锤的适应能力。

After analyzing work principle of grundomat hammer, this paper introduces using highpress hydraulic efflux in overhard soil layer and using lime gun in soft soil layer (more water) to enhance adapting capability of grundomat hammer.
