摘要
在四川省雅砻江两河口水电站库区复建县道X037线普巴绒特大桥承台大体积砼施工时,采取了配制低水化热的砼配合比,承台中设置水管通循环水冷却,承台外表面保温养护,养护期间严格温控等措施,避免了承台大体积砼产生温度应力裂缝。
In the large-volume concrete construction of the paclittic bridge of the rebuilt county road X037 line in the Shuanghekou Hydropower Station of the Yalong River in Sichuan Province, the concrete mix ratio of low hydration heat was taken. Water pipe is set in the cap which is access to circulating water for cooling. The outer surface of the cap has insulation conservation. There is strict temperature control during conservation. There measures have avoided the temperature stress cracks of the large concrete of the cap.
