Abstract

A chimney-tower-integrated structural system with oblique cable nets and its construction method. The chimney is combined with the air-cooling tower. The chimney adopts a reinforced concrete structure and is built in the center of the air-cooling tower. The air-cooling tower adopts a tension structure, and structural membrane materials are laid on the outside . The construction is assembled on the ground, then hoisted to a certain height, and fixed on the concrete chimney by cables. The lower part of the hyperbolic structural cable is stretched until the structure reaches a certain rigidity. In order to keep the chimney stable under pressure, a stay cable is set in the middle of the chimney and the foundation is anchored. By combining the chimney with the air-cooling tower, the present invention realizes the possibility of building an air-cooling tower with flexible materials, which can be spliced ​​and stretched on site; the method of hoisting after ground assembly is adopted, which effectively reduces high-altitude operations; can effectively save chimney construction land and reduce concrete Reduce the amount of wet work on site; the structural membrane material is light in weight and can achieve a higher height, and the chimney provides lateral support for the cable net, which can resist greater wind suction load.

Description

technical field [0001] The invention relates to a chimney-air cooling tower integrated structural system of a thermal power plant, in particular to a chimney tower integrated structural system of an oblique cable net and a construction method thereof. Background technique [0002] Due to the increasing shortage of construction land for power plant projects, the integration of chimneys and air cooling towers can reduce the construction project land. At present, most of the structures of indirect air cooling towers are reinforced concrete structures, and a few indirect air cooling towers are in the form of steel structures. The design methods and construction technologies are relatively mature, but they all need to be operated at high altitudes. The construction period is long, the amount of concrete is large, and the environment is polluted. Seriously, it is impossible to realize prefabricated construction. [0003] With the expansion of the scale and the improvement of the ...
