Main workshop structure of large heat power plant

Abstract

The invention relates to a main workshop structure of a large heat power plant, which comprises a turbine house, a deoxidizing bay and a bunker bay, wherein one side of the deoxidizing bay is adjacent to the turbine house, and the other side of the deoxidizing bay is adjacent to the bunker bay; a transverse shearing force wall and a longitudinal shearing force wall are dispersed at the circumferences of the bunker bay and the deoxidizing bay; frame columns of the deoxidizing bay and the bunker bay are profile steel concrete columns under the coal bucket layer; and the turbine house, the deoxidizing bay and the bunker bay integrally form a profile steel concrete frame-dispersed shearing force wall structure. The main workshop structure of the heat power plant is a main workshop structural system which is suitable for a high-capacity unit in an earthquake high-intensity area and has favorable structure performance and relatively low cost. Compared with the traditional system, the invention has the advantages of better quaking resistance, column section reduction, more convenient space process arrangement, low maintenance cost in later period, and the like.

Description

technical field [0001] The invention belongs to the technical field of plant design, and relates to a novel main plant structure system of a large-scale thermal power plant. Background technique [0002] In traditional small and medium-sized thermal power plants, due to the limitations of construction level and construction equipment, the structural system of the main plant is mainly prefabricated. With the improvement of construction level and construction machinery manufacturing and installation capabilities, the cast-in-place reinforced concrete structure replaces the fabricated structure system. In recent years, my country's iron and steel production capacity has increased substantially, and the unit capacity of thermal power plants has also continued to increase. Steel structure systems have begun to be used in high-intensity earthquake-resistant fortified areas. [0003] In recent years, most of the main workshops of new large-scale thermal power plants in my country ...

AI Technical Summary

Problems solved by technology

In civil buildings, there have been reports on steel concrete column-wall composite structures and reinforced concrete special-shaped joints and similar studies, but for the structural system of the main powerhouse of a thermal power plant, the structural members have large dimensions, many structural staggered floors, and large heterogeneity of joint stress and deformation. There are few research results for similar structural systems with large uneven distribution of stiffness and mass, poor horizontal structural continuity, and poor overall structural performance.
