摘要
趾板是整个混凝土面板堆石坝防渗系统的重要组成部分,可保证面板与坝基间的不透水连接.趾板基础是重要隐蔽工程之一,做好趾板基础开挖的质量控制工作,对于趾板施工非常重要.如果质量管理出现问题,很容易造成欠挖、超挖、尺寸不合理以及基础移位等各种各样的问题,从而对工程质量产生影响.所以大坝趾板基础开挖施工要严格按照设计和规范进行,现场施工要操作程序化、规范化,确保工程施工质量.
Abstract
Toe slab is an important component of the anti-seepage system of the entire concrete face rockfill dam,which can ensure an impermeable connection between the face slab and the dam foundation.Toe board foundation is one of the important concealed works.It is very important to do a good job in quality control of toe board foundation excavation for toe board construction.If there are problems with quality management,it is easy to cause various problems such as under excavation,over excavation,unreasonable dimensions,and foundation displacement,which can have an impact on the quality of the project.Therefore,the excavation construction of the dam toe slab foundation must be strictly carried out in accordance with the design and specifications,and on-site construction must be operated in a standardized and procedural manner to ensure the quality of the project construction.
