Abstract

The invention discloses an oblique pillar structure for a natural ventilation cooling tower and a construction method thereof. The structure includes a slanted strut structure, wherein the slanted strut structure consists of a plurality of strut frames interconnected to form a ring structure, and the strut frame is a steel pipe-concrete composite structure composed of steel pipes and concrete filled in the steel pipes; the strut frame includes a ring beam , piers and pillars, wherein the top of the pillars is connected to the ring beam, and the bottom end is connected to the piers; the pillars are X-shaped pillars or V-shaped pillars. The construction method is that the concrete in the inclined pillars and the concrete in the ring beam of the steel tube-concrete composite structure are poured from the bottom, and the one-time or segmented jacking method is poured, and the segmented ring beams are assembled into an integral ring beam by welding. The invention has the advantages of small cross-sectional size of the inclined pillar, good structural ductility, fast construction speed, long service life, relatively cheap construction cost of the whole tower, easy and low maintenance cost in the later period, and the like.

Description

technical field

[0001] The invention belongs to the technical field of industrial natural ventilation cooling towers, and in particular relates to an oblique pillar structure for a natural ventilation cooling tower and a construction method thereof. Background technique

[0002] Most of the large natural draft cooling towers use reinforced concrete structures, and a few use steel structures. Due to the limitation of construction level and construction equipment, most of the inclined pillars of the natural ventilation cooling tower adopt reinforced concrete cast-in-place structure, and a few adopt reinforced concrete prefabricated structure. Among them, the cast-in-place reinforced concrete slanted pillar is a structural system widely used in large-scale natural ventilation cooling towers that have been built or are under construction in my country because of its good integrity and low requirements for construction lifting equipment.
