Integral lifting construction method for cooling tower system and steel gallery

Abstract

The invention provides an integral lifting construction method for a cooling tower system and a steel gallery, which comprises the steps of 1) conducting pre-construction preparation, firstly buildinga cooling tower steel structure supporting foundation model, a cooling tower maintenance platform model and a pipeline support model, then building an integral structure model by combining the builtmodels with a cooling tower, a cooling water pipeline and a steel gallery, performing stress simulation analysis on the model, ensuring the stress of each part in the lifting process to meet requirements, and deepening the design of construction drawings; 2) splicing the cooling tower system and the steel gallery on the ground according to the construction drawings; and 3) and integrally and synchronously lifting the spliced cooling tower system and steel gallery through a hydraulic lifting system. According to the invention, the cooling tower system and the steel gallery are firstly spliced on the ground and then integrally lifted, thereby reducing the hoisting and splicing difficulty of components of the cooling tower system, and saving the labor. In addition, the components of the cooling tower system can be simultaneously spliced, thereby ensuring the construction period, improving the installation and construction quality and efficiency of the cooling tower system.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an integral lifting construction method of a cooling tower system and a steel corridor. Background technique [0002] At present, in order to reduce the potential safety hazards of the steel corridors in China, the method of reducing the weight of the steel corridors is generally adopted, only the frame of the steel corridors is assembled in place, and then the lifting is carried out. Boards, greening, equipment, etc. are all installed after the steel corridor is lifted and placed in place. [0003] The following construction problems exist when the cooling tower system is installed on the steel corridor by adopting the existing scheme of lifting the steel corridor first and then hoisting the equipment: [0004] 1. The cooling tower is large in size and heavy in weight. It also includes pipes and brackets. To hoist it to the installation height of the s...

AI Technical Summary

Problems solved by technology

[0006] 3. The hoisting construction of the cooling tower needs to wait until the overall hoisting of the steel corridor structure is completed, and then the concrete is poured, which seriously affects the construction progress of the mechanical and electrical equipment installation;

[0007] 4. The cross construction of steel structures and equipment pipelines may affect the overall stability of the steel corridor structure, especially factors such as operating weight and noise resonance have a major impact;

[0008] 5. There are great construction difficulties and safety risks in the installation of cooling tower systems for high-altitude operations
