郑州合众大厦建成后,人防地下室出现严重渗漏,渗漏面积约1200m~2,积水深度平均约1m。建设单位曾先后委托两家防水公司治理,但因设计方案不妥或防水材料选用不当,施工后均告失败。后经施工方组织有关人员检查分析与论证后,决定选用金汤牌JS复合防水涂料和金汤水不漏堵漏材料,采用串管引水堵漏先进施工工艺进行堵漏。堵漏工程于1997年5月竣工,竣工后进行检查验收,没有发现任何渗漏现象,堵漏效果显著。 一、堵漏方案 1.依据查勘结果及防水要求,本着“堵、防结合”的原则,决定采用串管引水堵漏的施工工艺。
After the completion of the Hezhong Building in Zhengzhou, there was a serious leakage in the basement of the civil air defense. The leakage area was about 1,200 m 2 and the depth of the accumulated water was about 1 m on average. The construction unit had entrusted two waterproof companies to govern, but due to improper design or improper selection of waterproof materials, they all failed after construction. After the construction party organized the relevant personnel to examine and analyze and demonstrate, it decided to use the Jinshen Brand JS composite waterproof coating and gold soup water leak-proof plugging materials, and adopt the advanced construction technology of string pipe diversion and drainage plugging to plug the leak. The plugging project was completed in May 1997 and inspections were carried out after the completion of the project. No leakage was found and the plugging effect was significant. First, the plugging program 1. Based on survey results and waterproof requirements, in line with the “blocking, anti-combination” principle, decided to use string pipe diversion of construction technology.
