小浪底工程泄洪系统技术复杂,工程规模大,对施工质量要求高,且进水口、导流洞和出水口等项目均位于工程施工关键线路上,在工程招投标阶段(承包商进场之前),业主对位于工程关键线路上的项目进行了提前施工,即采用分期施工,一期工程在国际承包商进场前施工完成。泄水工程的分期施工使业主和设计单位更进一步清楚小浪底工程的地质情况,为小浪底工程国际标招标创造了良好条件。值得一提的是小浪底泄洪系统高边坡处理措施,进水塔及出口消力塘混凝土施工ROTEC 系统及 DOKA 模板等先进施工技术以及排沙洞无粘结
Xiaolangdi project flood discharge system is complex, large-scale projects, high requirements on the construction quality, and intake, diversion tunnels and outlets and other projects are located in the construction of key lines in the project bidding stage (before the contractor approach) The owners of the project located on the key lines of the project carried out in advance construction, namely the use of staged construction, a project in the international contractor before the completion of construction. The phased construction of the spillway project enables the owner and the design agency to further understand the geological conditions of the Xiaolangdi Project and create favorable conditions for the international tender of the Xiaolangdi Project. It is worth mentioning that the Xiaolangdi flood control system of high slope treatment measures, inlet towers and outlet Xiaotang concrete construction ROTEC system and DOKA template and other advanced construction techniques and desert sand hole without bonding
