Abstract

The invention discloses a method for installing a large-size steel frame flue. The ground installation of the steel frame and the flue comprises the following steps that S1, a steel frame foundation is prepared, then a wire is laid out on the steel frame foundation, the flue installation position is marked, and the wall plate, the bottom plate and the top plate are arranged at the flue installation position; S2, the installation position of the steel frame upright post is marked at the wall plate; S3, an opening is opened at an installation position of the steel frame upright post, and the steel frame upright post is hang into the opening; S4, the steel frame body is arranged on the steel frame foundation; S5, an inverted top is installed; S6, the inverted jacks is lifted to finish a lifting stroke of the inverted lifting rods; and S7, after the lifting stroke of one of the reverse pulling rods is completed, the inverted jacks are lifted again, and the step S5 is repeated to complete the installation of the whole large-section flue. The method has the beneficial technical effects that the construction is safe, the construction period is short, the field requirements are few, and large hoisting equipment is not needed.

Description

technical field [0001] The invention relates to the technical field of installation of environmental protection equipment, in particular to a method for installing a large-volume steel frame flue. Background technique [0002] With the continuous improvement of environmental protection standards, the requirements for flue gas emission are becoming more and more stringent. The original environmental protection equipment of steel mills and power plants cannot meet the latest emission standards stipulated by the state. Only by upgrading or adding new environmental protection equipment can the emission requirements be met. [0003] Since most of the sintering machines in our country did not plan the environmental protection equipment site at the beginning of their construction, or the planning was small, and the environmental protection equipment installed in the early stage could meet the basic conditions of the design requirements at that time, most of the construction sites we...
