Key Construction Techniques of 4000 m~2 Hyperbolic Cooling Tower

摘要

Combined with a 2×350 MW gas power station project, the main construction process and specific technology of each subentry project for a large hyperbolic cooling tower were described in details. The customized steel templates were used and positioned by accurate calculation. The mass concrete was poured by alternative bay construction which replaced deformation joint and after-pouring belt. The measures such as controlling temperature, avoiding leakage and monitoring geometric size were taken actively. These methods greatly improve the quality of the structure and are strong guarantee for achieving high-quality project.
