土石围堰混凝土防渗墙防渗研究

Study on Seepage Prevention of Concrete Seepage Prevention Wall of Earth-Rock Cofferdam

目前,混凝土防渗墙施工技术已在我国各大土石坝(围堰)工程中得到了广泛应用,但在不同工程条件下,需要作出针对性的设计与布置,以取得更好的防渗效果。论文结合岷江航电犍为枢纽工程防渗墙施工工程,对混凝土防渗墙防渗施工技术进行分析,总结质量控制措施,以提高施工质量,为类似工程提出借鉴。

At present, concrete anti-seepage wall construction technology has been widely used in China's major earth-rock dams (cofferdams) project, but under different engineering conditions, it is necessary to make targeted design and layout to achieve better anti-seepage effect. In this paper, the anti-seepage construction technology of concrete anti-seepage wall is analyzed and summarized in combination with the anti-seepage wall construction project of Minjiang Avionics Jianwei Pivotal Project, analyzes the construction technology of concrete impermeable wall and summarizes the quality control measures to improve the construction quality and provide reference for si mi lar projects.
