摘要/Abstract

摘要： 防渗墙墙体槽段的连接部位是防渗墙防渗的薄弱环节，其连接质量是保证防渗墙整体防渗效果的关键，决定着防渗墙的成败。分析了防渗墙传统墙段接头形式的弊端，借鉴坝体接缝灌浆原理，设计研究了一种新型的防渗性能可靠的接缝灌浆式接头形式。介绍了其施工工艺、技术要点，对其可行性、效果以及效益等进行了分析。此技术有利于简化传统接头施工工艺、提高施工效率、缩短工期，且经济效益显著。

Abstract: The joint section of a cut-off wall is a very important location and its quality is crucial to ensure the anti-seepage effect of the cut-off wall and determines the success or failure of the cut-off wall. The shortcoming of the traditional joint type is analyzed. From joint grouting principle of the dam body, a new reliable joint grouting of joint type is studied. Construction technics and technology key points are introduced. The feasibility, effect and benefit of the new joint are analyzed. This technology helps simplify the traditional joint construction technology, improve the efficiency of constructi on and shorten the construction period. Significant economic benefits are obtained.
