Plugging method and plugging structure for large crack of concrete wall
The invention relates to a leaking stoppage method for a large crack of a concrete wall. The leaking stoppage method comprises the steps that 1, the crack is pretreated; step 2, crack filling; 3, grouting holes are formed; 4, crack sealing slurry is poured; step 5, plugging a grouting orifice; step 6, surface treatment; the invention further relates to a leaking stoppage structure of the concrete wall body large crack, the leaking stoppage structure comprises a concrete body, a U-shaped crack groove is formed in the position of a leakage seam of the downstream face of the concrete body, the width of the U-shaped crack groove is larger than that of the leakage seam, and a waterproof leaking stoppage layer is arranged in the U-shaped crack groove. The concrete body is further provided with a pouring hole extending into the concrete body, and the pouring hole penetrates through the section of the leakage seam. And crack sealing slurry is arranged in the pouring hole. The first waterproof leaking stoppage is formed on the surface of the leakage seam; and then, an inclined grouting hole structure is adopted, a second waterproof leaking stoppage is formed in the leakage seam, the effectiveness and durability of leaking stoppage are improved, and the problem that re-leakage is likely to occur in the existing leaking stoppage technology is solved.
本发明涉及一种混凝土墙体大裂缝的堵漏方法，包括：步骤1、裂缝预处理；步骤2、裂缝填充；步骤3、设置灌浆孔；步骤4、灌注裂缝密封浆料；步骤5、封堵灌浆孔口；步骤6、表面处理；还涉及一种混凝土墙体大裂缝的堵漏结构，包括混凝土体，在混凝土体的背水面的渗漏缝处设有U型裂缝槽，U型裂缝槽的宽度大于渗漏缝的宽度，U型裂缝槽的槽内设有防水堵漏层；混凝土体还设有延伸至混凝土体内部的灌注孔，且灌注孔穿过渗漏缝的断面；该灌注孔内设有裂缝密封浆料。本发明通过在渗漏缝的表面形成第一道防水堵漏；再采用倾斜的灌浆孔结构，在渗漏缝的内部形成第二道防水堵漏，提高了堵漏的有效性和持久性，解决了现有堵漏技术容易出现复漏的情况。
