Earth and rockfill dam anti-seepage treatment method
The invention discloses an earth and rockfill dam anti-seepage treatment method which comprises the following steps that (1) holes are distributed, specifically, two rows of grouting holes are formed in the position 1-2 m away from the inner side line of the original dam top of an earth and rockfill dam, the row distance of the grouting holes is 0.8-1.5 m, and the hole distance is 0.8-1.5 m; (2) drilling: forming a grouting hole at one time by adopting a down-the-hole drill of which the diameter is greater than phi 50mm; (3) slurrying: mixing cement, clay, yellow sand and water to prepare slurry; (4) grouting: filling the slurry through the grouting holes by adopting a bottom-to-top segmented grouting method; and (5) hole sealing is conducted, specifically, after grouting is completed, the grouting holes are sealed. The anti-seepage treatment method is convenient to construct, low in cost and capable of effectively improving the anti-seepage effect of the earth and rockfill dam.
本发明公开了一种土石坝防渗处理方法，包括以下步骤：(1)布孔：在距离土石坝的原堤顶内侧线1‑2m布置两排灌浆孔，灌浆孔的排距为0.8‑1.5m，孔距为0.8‑1.5m；(2)转孔：灌浆孔采用大于φ50mm的潜孔钻一次性成孔；(3)制浆：将水泥、粘土、黄砂及水混合制成浆料；(4)灌浆：将所述浆料通过所述灌浆孔采用自下而上分段灌浆法进行灌装；(5)封孔：灌浆结束后，将所述灌浆孔进行封孔。该防渗处理方法施工便捷，成本低且能有效提升土石坝的防渗效果。
