摘　　要：为解决混凝土施工缝处现有防水做法防水质量不高、防水年限过短、施工工艺烦琐等难点,对混凝土施工缝防水注浆管进行创新改进。针对现有一次性混凝土防水注浆管注浆效果欠佳,且只能一次性使用的问题,提出“连带阀门”式自动闭合注浆管,将一次性防水注浆管改进为可多次注浆,成功解决了传统防水工程中的质量问题以及施工工艺问题,弥补了防水工程中的缺陷,对同行业施工具有很好的参考价值。To solve the problems of poor waterproof quality,short waterproof life and tedious construction technology in the current waterproof methods at concrete construction joints,the waterproof grouting pipe for concrete construction joints is innovated and improved.As to the problem that the grouting effect of the existing disposable concrete waterproof grouting pipe is not good and can only be used once,the"joint valve"type automatic closing grouting pipe is put forward,which successfully solves the quality problems and construction technology problems in the traditional waterproof engineering,and made up for the defects in the waterproof engineering.It has a good reference value for the construction of the same industry.
