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。
By analyzing the working principle of the perforated hammer, it is proposed to use high-pressure water jet in the hard soil layer and to use the powder spraying technology in the soft soil layer (large water layer) to improve the adaptability of the perforating hammer.
