Problems solved by technology

Generally, the diameter of the herringbone columns used in medium-sized cooling towers is Ø500~Ø700mm. When the concrete is poured, personnel cannot enter the columns for vibrating operations, and the herringbone columns are difficult to vibrate and compact because of the bidirectional inclination of the con

Abstract

The invention relates to the technical field of cooling tower construction, and discloses a construction method for pouring a circular herringbone column of a cooling tower in a segmented mode. The method comprises the following operation steps that 1, construction preparation is carried out, specifically, a design construction drawing is familiarized, safe technical disclosure is carried out on construction workers, and meanwhile preparation work of materials, machines, tools and equipment is carried out. According to the construction method for pouring the circular herringbone column of thecooling tower in the segmented mode, a UPVC guide pipe discharging method is adopted in herringbone column concrete pouring construction, the problem that mixtures are separated due to the fact that the free falling height of concrete is large is mainly solved, a column top mold is covered and reinforced in a segmented mode, observation and manual auxiliary vibration can be convenient, two vibrating rods are adopted to work at the same time, and the problem that the use safety and durability of the structure are affected due to the fact that concrete is vibrated uncompactly can be effectivelysolved; and compared with a traditional pouring method, the construction method is simple in construction and easy to operate, and it can be effectively guaranteed that herringbone column concrete achieves the effect of solid inside and smooth outside.

Description

technical field [0001] The invention relates to the technical field of cooling tower construction, in particular to a construction method for segmented pouring cooling tower circular herringbone columns. Background technique [0002] The hyperbolic cooling tower is the landmark structure and project highlight of large thermal power plants. It consists of underground engineering, inclined pillar engineering, cylinder wall engineering, tower core structure engineering, water spraying and water distribution device engineering and auxiliary engineering. As the most important force-bearing component of the upper ventilator of the cooling tower, the inclined pillar (also known as the herringbone pillar), the quality of its construction will directly affect the structural performance and appearance quality of the cooling tower. Generally, the diameter of the herringbone column commonly used in medium-sized cooling towers is Ø500~Ø700mm. When the concrete is poured, personnel cannot...
