Curtain grouting method and drainage method of concrete dam
The invention discloses a curtain grouting method and drainage method of a concrete dam. The curtain grouting method and drainage method comprises the following steps that a curtain grouting gallery is arranged inside the concrete dam, curtain grouting holes are formed in the curtain grouting gallery, through the curtain grouting holes, an anti-seepage curtain is formed by grouting the bedrock needing to be grouted, temporary drainage holes are formed in the downstream of each curtain grouting hole in the curtain grouting gallery, and permanent drainage holes after supplementary grouting are formed in the curtain grouting gallery. By means of the curtain grouting method and drainage method, the disadvantage of the increase of construction period and costs due to rigid uniformity of the standard of traditional curtain grouting is avoided, the grouting purposefulness is high, the efficiency and convenience are achieved, and project investments can be greatly saved.
本发明公开了一种混凝土坝的帷幕灌浆方法和排水方法，混凝土坝内部设置帷幕灌浆廊道，帷幕灌浆廊道设置帷幕灌浆孔，通过帷幕灌浆孔对需要进行灌浆基岩灌浆形成防渗帷幕，帷幕灌浆廊道内帷幕灌浆孔下游设置临时排水孔，帷幕灌浆廊道内设置补充灌浆后的永久排水孔。本发明避免了传统帷幕灌浆标准一刀切造成工期、造价增加的缺点，灌浆目的性强，高效便利，能极大的节约工程投资。
