A two-way supporting large cooling tower

Abstract

The invention discloses a bidirectional supporting large-scale cooling tower which comprises a main drum, a supporting structure and an annular base. The bidirectional supporting large-scale cooling tower is characterized in that the supporting structure is arranged as a bidirectional supporting structure and comprises a plurality of outer circle braces and inner circle braces, wherein the inner circle braces and the outer circle braces are respectively arrayed into a circle in the form of herringbone or V-shaped structure along the annular direction of the annular base; along the axial direction of the annular base, the outer circle braces are inclined along the direction of a lower linear part of the main drum; along the radial direction of the annular base, the inner circle braces are in one-to-one correspondence to the outer circle braces; and the upper ends of the corresponding inner circle braces and outer circle braces are close to each other while the bottom ends are separated from each other, so that the herringbone or V-shaped structure along the radial direction is formed. The supporting structure of the bidirectional supporting large-scale cooling tower disclosed by the invention is safe and reliable; the wind-resisting and shake-resisting properties of the whole structure of the cooling tower can be guaranteed; compared with the cooling tower with an X-shaped brace, the bidirectional supporting large-scale cooling tower has the advantages that the construction difficulty is reduced, errors are difficult to occur in a mounting process, and the height of the air inlet of the large-scale cooling tower is increased while the stress of each brace is relieved; and the bidirectional supporting large-scale cooling tower is suitable for popularization and application.

Description

technical field [0001] The invention discloses a two-way supporting large-scale cooling tower, and relates to the technical field of construction of electric power systems and the technical field of large-scale towering structure design. Background technique [0002] As the world's largest reinforced concrete towering space shell structure, the cooling tower is an important structure for circulating water cooling in thermal / nuclear power plants. With the development of electric power construction technology, high-efficiency and large-capacity generator sets are mostly used in electric power projects, and the matching large-scale cooling tower technology is widely used in projects, especially in recent years when the tower height breaks through the specification limit in the design and planning. The demand for construction of ultra-large cooling towers is increasing day by day, and the large-scale hyperbolic thin-shell cooling tower that breaks the world record has been put o...

Problems solved by technology

And because the height of the inclined pillar is high, the formwork and the corresponding construction support system need to extend from the bottom surface of the pillar to the top surface, and it is difficult to control the deformation and stability of the support system with high formwork

[0004] In the field of ultra-large cooling towers, X-shaped pillars are widely used because of their strong lateral torsion resistance, but it is difficult to manufacture X-shaped pillars. The main stress bars are distributed in a cross pattern, but it is difficult to place the cross points. , local super-reinforcement is easy to appear, but in the construction process, the influence of the error of the inclined pillar on the wind and earthquake resistance of the overall structure of the large cooling tower cannot be ignored, so the construction difficulty of the X-shaped inclined pillar is even higher
