北京市水利工程基础处理总队研究的混凝土防渗墙体积代替法接头新工艺,在北京通过专家鉴定,该工艺为国内外首次采用,具有较高的技术水平和应用价值,达到了国际先进水平,并获国家发明专利。混凝土防渗墙接头施工工艺是防渗墙施工中的关键环节,目前国内外通常采用的是“套打一钻”法、接头管法、双反弧接头法、胶囊接头管法等,但因施工设备、工程质量要求原因,使超深和高标号混凝土防渗墙接头施工受
Beijing Water Conservancy Engineering Foundation Corps of concrete cutoff wall volume replacement method of joint new technology, in Beijing by experts, the technology for the first time at home and abroad, with high technical level and application value, reached the international advanced level, And won the national invention patents. The construction technology of concrete cutoff wall joint is the key link in the construction of cutoff wall. At present, it is commonly used at home and abroad, such as “Da Tuo Yi Zhu” method, pipe joint method, double anti-arc joint method and capsule joint pipe method, However, due to construction equipment, engineering quality requirements, so that ultra-deep and high-grade concrete cutoff wall joints construction by
