涟源钢铁厂三炼钢车间总建筑面积18658平方米,除炉子跨为瓦垄铁屋面外,其他均为15～18米预应力钢筋混凝土屋架、预应力自防水大型板屋面。用聚氯乙烯胶泥(以下简称胶泥)灌缝面积为12700平方米。胶泥作为防水接缝材料,已在全国推广,很多单位已经摸索了丰富经验,因此其一般施工操作过程就不再重复,仅就我们在施工中遇到的几个问题
The total construction area of the three steelmaking workshops of the Laiyuan Iron and Steel Plant is 18,658 square meters. Except for the cross-sections of the furnaces, they are prefabricated reinforced concrete trusses of 15 to 18 meters and prestressed self-waterproof large-plate roofs. With polyvinyl chloride cement (hereinafter referred to as cement) filling area of 12,700 square meters. As a waterproof joint material, cement has been promoted throughout the country, and many units have already explored a wealth of experience. Therefore, the general construction operation process will not be repeated. It is only a few problems we encountered during construction.
