静态爆破拆除法在水库除险加固工程中的应用

Application of static blasting demolition in reservoir reinforcement project

在水库除险加固工程中,经常会有水工混凝土建筑物部分拆除、部分保留,或者在新建水工建筑物附近拆除原有建筑物的情况。为此,通过清河水库除险加固工程溢洪道导流墙混凝土拆除施工实例,介绍静态爆破拆除法的施工工艺和方法,总结经验,指出施工注意事项。实践证明:该方法在拆除有保留部分混凝土及保护附近建筑物施工中,效果明显,值得类似工程借鉴和应用。

Local demolition of hydraulic concrete structures from retained parts, or demolition of old works nearby the newly constructed hydraulic structures is frequently seen during construction of reservoir reinforcement project. Taking concrete demolition of spillway guide wall for Qinghe Reservoir reinforcement Project as example, the author presented the construction technique and method of static blasting demolition, summarized experience and pointed out the issues in need of special attention. As shown by practice, static blasting has demonstrable effects during con-crete demolition from retained parts while protecting nearby buildings, so is worth of reference and application by similar projects.
