某水库保护性拆除专项施工方案

Special Construction Scheme for Protective Demolition of a Reservoir

某水库位于黄河流域沁河水系,建于20世纪60年代。因水库的长期运行,工程存在老化、人为破坏、自然侵蚀等现象,为了水库的继续安全运行,需要对水库存在的问题及隐患在除险加固的基础上进行保护性拆除。经综合分析论证,水库除险加固保护性拆除工程结构拆除时需对坝体进行保护,防止拆除过程中造成损伤,故采用人工与机械切割配合的模式进行拆除。文章根据水库的具体工程情况详细论述了水库保护性拆除的专项施工方案。

A reservoir is located in the Qin River system of the Yellow River basin and was built in the 1960s. Due to the long-term operation of the reservoir, aging, man-made damage, natural erosion and other phenomena exist in the project. In order to continue the safe operation of the reservoir, it is necessary to carry out protective removal of water inventory problems and hidden dangers on the basis of risk removal and reinforcement. Through comprehensive analysis and demonstration, the dam body needs to be protected during the structural demolition of the protective demolition project of reservoir reinforcement to prevent damage in the demolition process, so the mode of manual and mechanical cutting is adopted for demolition. According to the specific project situation of the reservoir, this paper discusses in detail the special construction scheme of the protective demolition of the reservoir.
