6月20日，金沙江旭龙水电站高线砂石加工系统成品粗骨料廊道首段浇筑完成，为电站成品骨料供应提供坚实保障。

旭龙水电站高线砂石加工系统承担大坝、引水发电系统和过鱼设施等电站主体建筑物混凝土骨料生产任务，占地面积约5.4万平方米，设计产能约每小时1257吨，共计划生产成品骨料约376.2万立方米。成品粗骨料堆场共设2条廊道，单条最长为 170.0米，最大堆料高度为22.0米。廊道结构采用箱式钢筋混凝土廊道，该廊道整体性好，结构形式刚度大，受力条件好，适应地基变形的能力强。

为确保旭龙水电站高线砂石加工系统成品粗骨料廊道混凝土顺利浇筑，金沙江旭龙公司始终贯彻落实集团公司“两高一低”工程建设要求，以“质量一流、科技领先、绿色智慧”为目标，强化业主主导作用，紧盯建设目标任务，强化过程有效管控，确保高质量完成重点车间浇筑，有序推进高线砂石加工系统工程建设。

On June 20, the first section of the finished coarse aggregate gallery of the sand and gravel processing system of Xulong Hydropower Station on the Jinsha River was completed, providing a solid guarantee for the supply of finished aggregate for the power station.

The high line sand and gravel processing system of Xurong Hydropower Station undertakes the concrete aggregate production task of the main building of the power station such as the dam, water power generation system and fish facilities, covering an area of about 54,000 square meters, with a designed capacity of about 1,257 tons per hour, and a total of 3,762 million cubic meters of finished aggregate planned to be produced. There are two corridors in the finished coarse aggregate storage yard, the longest of which is 170.0 meters and the maximum height of the bulk material is 22.0 meters. The corridor structure adopts box-type reinforced concrete corridor, which has good integrity, large structural rigidity, good force condition and strong ability to adapt to foundation deformation.

In order to ensure the smooth pouring of finished coarse aggregate gallery concrete of Xulong Hydropower Station high line sand and gravel processing system, Jinshajiang Xulong Company has always implemented the construction requirements of the "two high and one low" project of the Group company, with the goal of "first-class quality, leading technology and green wisdom", strengthened the leading role of the owner, focused on the construction objectives and tasks, and strengthened the effective control of the process. Ensure the completion of the key workshop pouring with high quality, and orderly promote the construction of the sand and gravel processing system of the high line.
