摘　　要：地处高原气候寒冷地区的犁地坪水库采用具有科技含量高、物理力学性能好、施工工艺简单、使用年限长的新型无溶剂、无污染的环保型现场固化成型施工技术——喷涂聚脲弹性体技术进行混凝土面板坝大面积的面板裂缝处理,聚脲防水涂料的涂层厚度仅有2.0 mm;工程投入运行现已进入第四年,水库蓄水至高于正常蓄水位1.3 m的最高水位时,下游坝脚渗流观测值为9.63 L/s,渗流水水质清澈,防渗效果很好。该技术以其优异的防渗、防腐、耐磨和耐老化性能,在水利水电工程等领域具有广阔的应用前景。The site curing construction technology was used to the Lidiping reservoir, which is located in the plateau climate cold areas. The technology is characterized by high technology content, physical and good mechanical properties, and simple aonstruction process. Moreover, the technology adopts a new sol- vent-sree, which can be used for a long time, and pollution-free environment-friendly construction technolo- gy, namely an elastic technology, of spraying polyurea. The technology is to trea the large-area panel cracks of the concrete face dam. Polyurea waterproofing paint coating is only 2.0 mm. Project has now en- tered its fourth year sina it was put intooperation. The seepage observation downstream of the dam foot is 9.63 L/s, when the reservoir reaches the highest level, which is 1.3m higher than the normal level. The seepage water quality is clear, and seepage effect is good. The technology for its excellent seepage, sorro- sion, abrasion and anti-aging properties,has broad application prospects in the field of water resources and hydropower engineering.
