溢流面翻模抹面施工技术在乐昌峡拦河坝工程中的应用

Application of the Overflow up the Plaster Mould Construction Technique to the Lechangxia Barrage Project

乐昌峡水利枢纽拦河坝工程采用了翻模抹面施工技术连续施工,并通过调整外加剂掺量控制塌落度,成功地一次完成施工,且混凝土表面光滑平整、曲线优美,值得类似工程借鉴。

High barrage overflow surface shape is complex , with high-grade concrete , so the requirement of surface is flat and smooth, and no cracks .Double plaster mould construction technology of continuous construction is applied in this project .By adjusting the additive content control slump , the construction successfully has been completed by one-off, and the concrete surface is flat and smooth , with the beautiful curve , which is worthy of reference for the similar projects .
