高摩赞水利枢纽工程大坝溢流面常态混凝土与RCC大坝主体同步浇筑施工技术

Construction technique for synchronous placement of conventional concrete overflow surface and main RCC structure of dam for Gomal Zam Water Control Project

本文介绍了高摩赞水利枢纽工程大坝溢流面常态混凝土与RCC碾压混凝土主体同步上升浇筑的施工原理、施工程序、施工方法和施工特点,并结合在高摩赞大坝工程中所取得的预期应用效果,得出该施工技术不仅有效保证了溢流面常态混凝土的施工质量,而且也不会由于溢流面常态混凝土的施工进度制约碾压混凝土筑坝施工技术所具有上坝强度高、缩短工期等优点的结论。

The principle,procedure,method and characteristics of the construction with the technology of the synchronous placement of both the conventional concrete overflow surface and the main RCC structure of the dam for Gomal Zam Water Control Project are described herein,and then a conclusion is made in combination with the expected application effect obtained from the construction of the dam that the construction technology cannot only effectively ensure the construction quality of the conventional concrete of the overflow surface,but can also not restrict the merits of the RCC Dam construction technique,i.e.high concrete placement intensity,short construction period,etc.
