Problems solved by technology

In this construction process, it is difficult to control the chimney diameter and chimney wall thickness with internal and external qualitative formwork, and the diameter of the chimney gradually decreases from bottom to top, resulting in more pockmarked appearance and the second manual plastering
And after long-term use, the outer skin is easy to fall off, and the quality seriously does not meet the requirements

Abstract

The invention discloses a chimney hydraulic formwork lifting device and a construction method. The chimney hydraulic formwork lifting device comprises a chimney foundation, an operation platform, a plurality of sets of lifting devices and a control element; and each set of lifting device is correspondingly provided with a formwork set. The chimney hydraulic formwork lifting device is characterized in that each set of lifting device comprises a supporting rod with one end embedded in the chimney foundation, a hydraulic jack capable of climbing along the supporting rod and a hydraulic pump station; the hydraulic pump station of each set of lifting device is connected with the control element; the operation platform is fixedly connected with the hydraulic jacks; and the formwork sets are arranged on the outer side of the chimney cylinder wall, and the outer sides of the formwork sets are fixedly connected with the operation platform. The chimney hydraulic formwork lifting device is simple in structure, high in construction efficiency and capable of effectively controlling the diameter of a chimney.

Description

technical field [0001] The invention relates to the technical field of chimney construction. More specifically, the present invention relates to a chimney hydraulic mold lifting device and a construction method. Background technique [0002] Chimney exhaust is a commonly used smoke exhaust method in the domestic chemical and electric power industries. Existing chimneys can be roughly divided into three types: brick chimneys, reinforced concrete chimneys and steel chimneys. When constructing reinforced concrete chimneys, traditional hydraulic internal and external Sliding form: that is, the derrick is assembled and manufactured first, the derrick is manufactured and installed in place, and then the construction platform installation, hydraulic system installation, electrical equipment installation, safety net installation, and hanging cage installation are carried out. The sliding form is performed every certain distance to form a cone. Physical chimney. In this constructio...
