冶金企业有很多面积较大,埋置较深,而且受高温影响的地下工程,如:炼钢厂的平炉基础,轧钢厂的加热炉、均热炉基础等。这些工程防水要求都很严格。目前,这类大工程主要有三种防水的办法,即:钢板防水、防水混凝土防水和渗排水措施。这三种措施中,采用钢板防水,防水效果是靠得住的,但成本比较高,施工技术比较复杂;采用防水混凝土防水,一般大面上没有漏水问题,但由于混凝土受热后出现 Metallurgical enterprises have a lot of large-scale, buried deep underground projects that are affected by high temperatures, such as the open hearth of the steelmaking plant, the heating furnace of the steel rolling mill, and the base of the soaking furnace. The waterproof requirements of these projects are very strict. At present, there are mainly three kinds of waterproofing methods for such large projects: waterproofing of steel plates, waterproofing of waterproof concrete, and drainage and drainage measures. Among the three measures, the use of waterproof steel plate, waterproof effect is reliable, but the cost is relatively high, the construction technology is more complex; using waterproof concrete waterproof, generally no water leakage on the large surface, but due to heat after the emergence of concrete
