冶金企业加热炉、均热炉等热工设备基础，都有严格的防渗漏要求。我公司在设备检修中，利用改造原防水结构，形成新、旧钢板加劲夹套──水泥压力灌浆综合防水结构，施工速度快，防渗效果好。鞍钢无缝钢管厂140机组3号加热炉更换防水钢板工程量大、工期长，对基础的防渗漏有很 Metallurgical enterprises, such as heating furnaces, soaking furnaces and other thermal equipment, have strict anti-leakage requirements. In the maintenance of the equipment, our company has used the original waterproof structure to form a new and old steel reinforcement jacket—an integrated waterproof structure for cement pressure grouting. The construction speed is fast and the anti-seepage effect is good. Anshan Iron and Steel Seamless Steel Tube Plant No. 3 of the No. 3 reheating furnace of the No. 1 unit of the Anshan Iron and Steel Works has replaced the waterproof steel plate with a large amount of work and a long construction period.
