| 摘 要： | 混凝土面板堆石坝是以堆石体为支承结构,在其上游表面浇筑钢筋混凝土面板作为防渗结构的堆石坝。堆石坝的沉降变形关系到大坝的安全,是判定大坝运行状况的重要指标。为了解决混凝土面板堆石(砂砾石)坝面板下部的电磁沉降管在面板施工时被废弃的问题,本文介绍了一种成工的电磁沉降管弯管施工工艺。通过对该工艺的运用,南湃水电站电磁沉降管成活率高,同时节约了大量的经济成本。

| Abstract: | CFRD is a rockfill dam with rockfill body as supporting structure and reinforced concrete face slab as impervious structure on its upstream surface. The settlement and deformation of rockfill dam is related to the safety of the dam, which is an important index to determine the operation status of the dam. In order to solve the problem of destroying the electromagnetic settlement pipe in the lower part of concrete face rockfill (gravel) dam during the construction of face slab, this paper introduces a successful construction technology of electromagnetic settlement pipe bending. By applying of this technology, the survival rate of the electromagnetic settlement pipe of Nam Phay Hydropower Station becomes higher, and much economic costs are saved. |
