摘要
介绍了钢筋混凝土双曲线薄壁冷却塔定向爆破拆除技术特点和工程实践。给出了这类薄壁结构物爆破拆除的设计方法,通过采取合理的预拆除、合适的爆破切口和优化的爆破参数,保证这类建筑物定向爆破拆除的安全,达到减少炮孔数量、定向准确和倒塌顺利的爆破效果。
The paper introduced the directional blasting remove technical features and the project practices of the reinforced concrete hyperbola shell structure cooling tower. The paper provided the design method of the blasting to remove the shell structure. With the rational pre-removing, rational blasting cutting and optimized blasting parameters, the safety of the directional blasting removing those buildings can be allowed and the number of the blasting boreholes can be reduced. A blasting results with correct directional blasting and completed building failure can be obtained.
