在冶金建筑工程中,热连轧机基础、连铸机基础等大型设备基础平面几何尺寸都比较大,长度方向尺寸短则十几米,长则数百米,基础形状复杂,基础顶面标高较多,预埋地脚螺栓,预埋套筒及预留螺栓孔数量可多达百余个乃至数千个,其中预留螺栓孔占有很大比例,它们相互交错布置在不同的标高位置,施工精度要求非常高,施工难
In the metallurgical construction project, the basic plane geometry of large-scale equipment such as hot strip mill foundation and continuous casting machine foundation is relatively large. The length dimension is shorter than 10 meters and is several hundred meters long. The basic shape is complex, and the elevation of the foundation surface is higher. The number of pre-embedded anchor bolts, embedded sleeves and reserved bolt holes can be as many as one hundred or even several thousand. Among them, reserved bolt holes occupy a large proportion, they are alternately arranged at different elevations, and construction accuracy Very high requirements, difficult construction
