Abstract

The invention discloses an integrally-tensioned integrated chimney and cooling tower structure system and a construction method thereof. According to the system, a chimney and an air cooling tower arecombined, the chimney is of a reinforced concrete structure and is built in the center of the air cooling tower, the air cooling tower is of a tensioning structure, and structural membrane materialsare laid on the outer side of the air cooling tower; ground assembly is adopted in construction, then the chimney is hoisted to a certain height, and the chimney is fixed to a concrete chimney throughstay cables; and the lower portion of a hyperbolic structure cable is tensioned until the structure reaches a certain rigidity, and an inhaul cable is arranged in the middle of the chimney to be anchored to a foundation in order to enable the chimney to keep certain compression stability. According to the system, the chimney is combined with the air cooling tower, so that the possibility of building the air cooling tower by using a flexible material is realized, and the air cooling tower can be spliced and tensioned on site; the mode of hoisting after ground assembly is adopted, so that high-altitude operation is effectively reduced; chimney construction land can be effectively saved, the using amount of concrete is reduced, and on-site wet operation is reduced; and the structural membrane material is light in self weight and can achieve a higher height, and the chimney provides lateral support for the cable net and can resist a larger wind suction load.

Description

Technical field[0001]The invention relates to an integrated structure system of a chimney and an air cooling tower of a thermal power plant, in particular to an integrally stretched smoke tower integrated structure system and a construction method thereof.Background technique[0002]As the construction land for power plant projects is becoming increasingly scarce, the combination of chimneys and air cooling towers can reduce the land used for construction projects. At present, the structure of indirect air cooling towers is mostly reinforced concrete. A few indirect air cooling towers are steel structures. The design methods and construction techniques 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, prefabricated construction cannot be realized.[0003]With the expansion of the scale of production of high-performance cables and the improvement of quali...
