摘要:
在航道建设工程中，施工重点在于对碍航滩段的综合性整治。目前，水下钻孔爆破已成为航道整治中效率最高的清礁方法。在进行水下钻孔爆破时，首先需考虑水深的影响，确定出适合工程的炸药和起爆器材，确保爆破效果。结合三峡-葛洲坝两坝间莲沱段航道整治工程，对深水条件下雷管的环境适应性进行研究，具体关注水深对雷管性能的影响。结果表明：在水下钻孔爆破施工时，当水深为0~40 m时，推荐使用高精度塑料导爆管雷管与数码雷管；同时，需根据工程实际情况选用雷管。当水深为50 m及以上时，推荐使用数码雷管，因为在高压与长时间浸水条件下，数码雷管性能的下降程度相对较小。
Abstract:
In the waterway construction project, the construction focus is on the comprehensive regulation of the obstructed section. At present, underwater drilling and blasting has become the most efficient approach for waterway regulation. During underwater drilling and blasting, the influence of water depth should be considered first to determine the suitable explosives and blasting equipment for the project, ensuring the blasting outcomes. Based on the waterway regulation project of the Liantuo section between Three Gorges Dam and Gezhouba Dam, the environmental adaptability of detonators under deep water conditions was studied, with a specific focus on the impact of water depth on the performance of detonators. The results indicate that high-precision plastic nonel detonators and digital detonators are recommended for underwater drilling and blasting construction when the water depth is 0-40 meters. Detonators should be selected according to the actual situation of the project. When the water depth is 50 meters or more, it is recommended to use digital detonators. Because under high pressure and prolonged immersion conditions, the performance degradation of digital detonators is relatively small.
