南水北调中线兴隆水电站厂房基础采用水泥搅拌桩复合基础,搅拌桩及建基面之间设计铺设20cm厚水泥砂褥垫层,其上部再浇筑10cm厚C10垫层混凝土。由于水泥砂褥垫层较少使用,为确保工程质量,委托有资质的专业单位进行室内试验、生产性试验。精心组织实施,取得较为详细的试验数据,为后期工程顺利实施打下良好基础。
The middle of the South-to-North Water Diversion Project is based on the composite foundation of cement mixing piles. The 20cm-thick cement sand mattress is designed and laid between the mixing piles and the foundation. The upper part of the foundation is then poured with 10cm thick C10 concrete. As less use of cement sand mattress, in order to ensure the quality of the project, commissioned a qualified professional unit for indoor test, production test. Meticulously organize the implementation and obtain more detailed experimental data, laying a good foundation for the smooth implementation of the later period projects.
