随着社会经济的发展,对水利工程需要量不断增加,溢流堰混凝土施工是水利工程施工过程中经常使用到的施工技术,但是由于溢流堰混凝土施工的起步比较晚,和很多发达国家相比还存在不小的差距。在溢流堰混凝土施工过程中经常会出现裂缝,是困扰施工企业多年的问题之一。溢流堰混凝土施工的断面比较大,在混凝土浇筑过程中,需要通过采取优化配比、分层浇筑等方式控制混凝土浇筑过程中产生的水化热,从而防止混凝土产生裂缝。文章通过在江西省水利水电建设有限公司多年的工作经验和相关文献的参考,并结合某水利工程具体的实际案例对溢流堰混凝土施工裂缝的预防措施进行深入探究,希望对我国溢流堰混凝土施工有一定帮助。
With the development of society and economy, the demand for water conservancy projects is increasing. Concrete construction of weir is a construction technique frequently used in construction of water conservancy projects. However, due to the relatively late start of construction of weir concrete and many developed countries Than there is still a small gap. Cracks often appear in the construction process of weir concrete, which is one of the problems plaguing construction enterprises for many years. Weir concrete construction section is relatively large, concrete pouring process, the need to optimize the ratio, layered pouring and other ways to control the heat generated during concrete pouring process to prevent cracks in concrete. Through the years of work experience and related references in Jiangxi Provincial Water Conservancy and Hydropower Construction Co., Ltd., combined with the concrete practical case of a water conservancy project, the article makes a deep research on the prevention measures of concrete weir cracks in the construction of our country. Construction has some help.
