Hydraulic engineering concrete dam leakage repairing and reinforcing grouting method
The invention discloses a hydraulic engineering concrete dam leakage repairing and reinforcing grouting method, which comprises the following steps of: determining a leakage part of a dam, and evaluating a leakage crack of the leakage part: when the leakage crack is more than 0.2 mm, performing medium-pressure grouting by adopting a cement-based grouting material, and ensuring that the medium-pressure grouting pressure is 1/2 of the maximum allowable grouting pressure; performing low-pressure grouting by adopting a chemical grouting material, wherein the low-pressure grouting pressure is the minimum value of 1/5 and 0.6 MPa of the maximum allowable grouting pressure; and when the leakage cracks are smaller than or equal to 0.2 mm, directly adopting chemical grouting materials for low-pressure grouting, wherein the low-pressure grouting pressure is the maximum value of 1/5 and 0.6 MPa of the maximum allowable grouting pressure; wherein the chemical grouting material comprises epoxy resin, acrylamide or polyurethane. The hydraulic engineering concrete dam leakage repairing and reinforcing grouting method is suitable for grouting construction of leakage repairing of cracks with various widths of the concrete dam.
本发明公开了一种水利工程混凝土坝补漏加固注浆方法，确定大坝的渗漏部位，评估渗漏部位的渗漏裂隙：当渗漏裂隙＞0.2mm时，先采用水泥基注浆材料中压注浆，中压注浆压力为最大容许注浆压力的1/2；再采用化学注浆材料低压注浆，低压注浆压力为最大容许注浆压力的1/5和0.6MPa中的最小值；当渗漏裂隙≤0.2mm时，直接采用化学注浆材料低压注浆，低压注浆压力为最大容许注浆压力的1/5和0.6MPa中的最大值；化学注浆材料包括环氧树脂类、丙烯酰胺类或聚氨脂类。该水利工程混凝土坝补漏加固注浆方法适用于混凝土坝各种宽度的裂缝补漏的注浆施工。
