钢筋混凝土烟囱的滑模施工,由于受到各种因素的影响,在滑升过程中,很容易发生平台扭转偏移。特别是简首直径小的高耸烟囱,滑得越高,扭转就越难控制。《烟囱工程施工及验收规范(GBJ7—64)》中,只将筒身中心线的垂直误差及筒壁厚度和筒身任何截面上的直径误差作为烟囱滑模施工的质量验评量度指标。因此,在烟囱滑模施工中,平
Slipform construction of reinforced concrete chimneys is susceptible to various factors and it is very easy for the platform to twist and shift in the process of sliding. In particular, the tall chimney with a small diameter and a small diameter, the higher the slide, the more difficult it is to reverse. In the “Code for the Construction and Acceptance of Chimneys (GBJ7-64)”, only the vertical error of the center line of the shaft body and the thickness of the wall of the shaft and the diameter of any section of the shaft are used as indicators for the quality inspection of the chimney slipform construction. Therefore, in the chimney slipform construction, flat
