The invention relates to an anti-seepage curtain reinforcing method. The method is suitable for the technical field of water conservancy and hydropower engineering. The technical problem to be solved by the invention is to provide the impermeable curtain reinforcing method so as to effectively improve the integrity and compactness of local weak parts of an original curtain body and dam body concrete, thereby improving the impermeability and keeping the durability of a grouting curtain. According to the technical scheme, the anti-seepage curtain reinforcing method is characterized in that grouting is conducted on curtain grouting holes in a segmented mode, portland cement is adopted for grouting of hole sections with the permeable rate larger than 10 Lu before grouting, and mineral slag powder or fly ash is doped in the cement; and for the hole section with the permeable rate smaller than or equal to 10 Lu before grouting, superfine cement with erosion resistance is adopted for grouting.
本发明涉及一种防渗帷幕补强方法。本发明适用于水利水电工程技术领域。本发明要解决的技术问题是：提供一种防渗帷幕补强方法，以使原帷幕体及坝体混凝土局部薄弱部位的完整性和密实性得到有效的改善，从而提高抗渗性，保持灌浆帷幕的耐久性。本发明所采用的技术方案是：一种防渗帷幕补强方法，其特征在于：分段对帷幕灌浆孔进行灌浆，其中对于灌前透水率大于10Lu的孔段，采用硅酸盐水泥灌浆，并在在水泥中掺矿碴粉或粉煤灰；对于灌前透水率小于等于10Lu的孔段，采用抗侵蚀性能的超细水泥灌浆。
