山西省霍县李家庄煤矿热电车间烟囱全高120米,筒身在±0.000米处外径为8.91米,内径仅有2.74米。±0.000米和120米处的筒壁混凝土厚度分别是450毫米和230毫米。其变截面坡度分为三种情况:±0.000～17.000米段、17.000～100.000米段和100.000～120.000米段分别为5%、2%和0%。筒身的全断面为复合壁板,其内衬为 M5抗酸盐水泥砂浆砌筑MU10机砖.4.545～17.000米段和17.000米以上段,分别为240毫米和
The total height of the chimney in the thermoelectric workshop of the Lijiazhuang Coal Mine in Huo County, Shanxi Province is 120 meters. The outer diameter of the barrel at ±0.000 meters is 8.91 meters and the inner diameter is only 2.74 meters. The wall thickness of concrete at ±0.000 meters and 120 meters is 450 mm and 230 mm, respectively. The variable section slope is divided into three cases: ±0.000 to 17.000 meters, 17.000 to 100.000 meters, and 100.000 to 120.000 meters are 5%, 2%, and 0%, respectively. The full section of the barrel is a composite wall plate lined with M5 salt-resistant cement mortar masonry MU10 bricks. The sections from 4.545 to 17.000 meters and 17.000 meters above are respectively 240 mm and
