我国冶金工厂钢筋混凝土烟囱,通常采用粘土砖作为衬壁,筒身、衬壁之间放有隔热层。施工这样的烟囱,过去采用先筒身后内衬的“单滑”方案。筒身采用滑模施工后再砌内衬,施工繁琐,绝对工期长。近年来一些单位相继采用简身、内衬同时滑升的 The reinforced concrete chimneys of China’s metallurgical factories usually use clay bricks as linings, and a heat-insulating layer is placed between the barrels and linings. The construction of such a chimney has used a “slip-on” scheme with a lining after the barrel. The barrel body is constructed with sliding mode and then lined with interior lining. The construction is tedious and the construction period is long. In recent years, some units have followed the concept of ingenuity, lining and sliding at the same time.
