大雁矿务局位于大兴安岭高寒地区,室外最低气温为-45～-52℃,采暖建筑物的外墙及屋顶厚重,基础深大,三材、红砖及人工消耗甚多,单位工程造价昂贵,使投资效果的发挥受到限制,我处设计技术人员刻苦钻研新技术,在严寒地区防寒建筑物采用水泥珍珠岩保温内衬问题上,深入现场,向实践学习,取到了初步成果。一、水泥珍珠岩内衬的部位及施工方法
Dayan Mining Bureau is located in the alpine area of Daxing’an Mountains. The minimum outdoor temperature is -45 to -52°C. The external walls and roofs of heating buildings are heavy, the foundations are deep, and the consumption of three materials, red bricks, and labor is very high. The cost of unit projects is expensive. The investment effect was limited, and our design engineers worked hard to delve into new technologies. In cold areas of cold areas, the use of cement perlite insulation lining, went deep into the scene, learned from practice, and achieved initial results. I. The location and construction method of cement perlite lining
