宝山钢铁厂均热炉钢筋混凝土烟囱共有六座,直径较小,规格相同,一期工程修建五座。由于烟囱施工安排在厂房钢结构安装之后,场地狭窄,工期紧,施工条件差。经研究决定采用液压滑模施工方案。目前国内钢筋混凝土烟囱液压滑模施工,多采用无井架内上料施工工艺,这对直径较小的烟囱来说,施工到顶部,狭窄的内工作台有时会给施工操作带来异常困难。鉴于这种情况,在探求均热炉烟囱滑模施工方案时,设想在滑模操作台上,架设一
The Baoshan Iron and Steel Plant has a total of six homogenous furnaces reinforced concrete chimneys with smaller diameters and the same specifications, and five phases of the first phase of the project. Since the chimney construction is arranged after the steel structure of the factory is installed, the site is narrow, the construction period is tight, and the construction conditions are poor. After the study decided to use hydraulic sliding mode construction program. At present, the domestic hydraulic reinforced concrete chimney hydraulic sliding mode construction, the use of non-headframe construction techniques, this construction of the smaller diameter chimney to the top, the narrow inner working platform sometimes brings unusual difficulties to the construction operations. In view of this situation, in the search for the construction plan of the soaking furnace chimney sliding mode, it is envisaged to set up a sliding mode operation platform.
