在以往冷却塔或烟囱施工中，由于不能及时观察到混凝土浇注过程是否处于稳定状态及出现异常现象，无法进行预防和纠正。在对筒壁半径的控制过程中，也存在着类似的问题。而采用控制图的方法能够正确判断、预防和纠正施工中混凝土方面出现的异常现象，做到防患于未然。应用于冷却塔及烟囱筒壁半径的控制方面，将对筒壁的表面工艺施工质量起到事半功倍的效果。 In the past, in the construction of a cooling tower or a chimney, prevention and correction cannot be performed because it cannot be observed in a timely manner whether the concrete pouring process is in a stable state and an abnormal phenomenon occurs. In the process of controlling the wall radius, there are similar problems. The use of the control chart method can correctly determine, prevent and correct the abnormal phenomena in the construction of concrete, so as to take preventive measures. Applied to the control of the radius of the cooling tower and the chimney wall, it will have a multiplier effect on the quality of the surface process of the cylinder wall.
