摘要
水下炸礁是工程爆破的重要组成部分,但是其施工的周边环境复杂、爆破技术难度较大、受河水影响控制较难。为解决水下钻孔爆破施工的困难,以施怡滩水下炸礁工程为背景,仔细梳理该工程项目的周边环境、水下礁石特性等情况,通过探索水下炸礁施工过程中的关键技术,精细设计孔网参数等方法,顺利实施水下礁石爆破。结果表明施怡滩水下炸礁取得了良好的爆破效果,并对周边民用建筑未造成有害的影响,爆破孔网参数可为其他类似的水下炸礁爆破工程提供一定的参考和借鉴。
Underwater reef blasting is an important part of engineering blasting.The surrounding environment of its construction is complicated,the blasting technology is difficult,and it is difficult to control the influence of river water.In order to solve the difficulties of underwater drilling and blasting,the Shiyitan underwater reef blasting project is taken as the study object,and the surrounding environment and underwater reef characteristics of the project are carefully sorted out.The key technologies in the construction of underwater reef blasting is explored,the hole network parameters are finely designed,and the underwater reef blasting is successfully implemented.The results show that underwater reef blasting has achieved a good blasting effect and has no harmful effects on the surrounding civil buildings.The blasting parameters can provide a reference for other similar underwater reef blasting projects.
