摘要
为选取用于河北武强220 k V变电站屋面的最优防水方案,设计了6个不同防水方案的试件进行试验研究。在试件中预埋应变计用于测试防水卷材和混凝土板的温度应变,得到应变随温度变化的规律。试验结果表明,从下至上采用"单组分聚氨酯防水涂料层+聚合物防水砂浆层+热塑性聚烯烃高分子防水卷材"的组合形式,应变协调性好,试件的防水性能最好。
In order to select optimal waterproofing program of Hebei Wu Qiang 220KV substati on roof, six waterproofing specimens are tested for research. Tests adopt strain gauges to measure te mperature strain of waterproofing membrane and concrete slab to achieve the change rule of tempera ture and strain. The results show that, the specimen, which adopts the combination form of ＂single- component polyurethane waterproof coating layer ＋ polymer waterproof mortar layer ＋ thermoplastic pol yolefin polymer waterproofing membrane＂ from bottom to up, achieves the best waterproof.
