摘要
某大型水电站导流隧洞混凝土堵头回填灌浆实施过程中出现了异常渗漏水情况,必须采取有效措施对堵头漏水进行封堵,分析漏水原因后,确定采用水溶性聚氨酯材料进行化学灌浆封堵,经过现场封堵灌浆实施,堵头漏水完全堵住,满足了水库正常蓄水运行要求。
Abnormal leakage happens to the concrete plug of diversion tunnel of a large-scale hydropower station during backfill grouting, and effective measures have to be taken to block the leakage. After leaking cause analysis, water-soluble polyurethane material is decided to be used for chemical grouting. The leakage is completely and successfully blocked, and the reservoir finally meets the requirements of normal working conditions.
