防渗技术在莒南青口河橡胶坝泵房施工中的应用

Application of Seepage Prevention Technology in the Pumping Station construction of Qingkou River Rubber Dam in Junan

摘要:

橡胶坝泵房施工时挖深深度大,地下水位相对建基面较高,且伴随基础沉陷和混凝土收缩等方面因素影响,在实际施工中,泵房渗水和漏水情况普遍存在,导致钢筋混凝土结构腐蚀,影响结构安全。文章以莒南县青口河橡胶坝泵房施工为例,分析泵房施工过程中常见的问题,从施工前排水措施、刚性防水、柔性防水、施工缝、穿墙管道等产生渗漏方面入手,提出处理措施,使泵房实际施工过程中更趋于安全可靠,为类似施工提供参考。

Abstract:

During the construction of the rubber dam pumping station, the excavation depth is large, and the groundwater level is relatively high compared to the foundation base surface, as well, it is influenced by factors such as foundation settlement and concrete shrinkage. Therefore, the seepage and water leakage in the pumping station are common problems in the actual construction process. This will lead to the corrosion of the reinforced concrete structure and affect the structural safety. Taking the construction of the pumping station of Qingkou River rubber dam in Junan County as an example, this article analyzes the common problems in the construction process of the pumping station. Starting from the aspects of drainage measures before construction, rigid waterproofing, flexible waterproofing, construction joints, and leakage at the pipes passing through the wall, it proposes treatment measures to make the actual construction process of the pumping station safer and more reliable, providing a reference for similar construction projects.
