Fabricated construction method of railway deck components

Abstract

The invention discloses a fabricated construction method of railway deck components. According to the method, centralized prefabrication, periodical quantitative fixed-point centralized transportationand fabricated installation operation are carried out, the construction problem of prefabrication, storage, transportation, installation and wet connection of deck prefabricated components is solved,a prefabrication field is saved, the cost investment is effectively controlled, the construction efficiency is improved, energy consumption is saved, an automatic, mechanized, factory-like and informationalized operation mode is provided, the prefabrication quality of the deck prefabricated components is improved, the storage cost and the component damage rate are reduced, installation equipmentand tools are simple and easy to operate, the construction speed is high, the construction quality is stable, the production efficiency is greatly improved, the construction quality is improved, laborand labour service investment can be effectively reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to the construction field of railway bridge deck components, in particular to an assembled construction method of railway bridge deck components. Background technique [0002] The construction method of bridge deck components in the current railway bridge construction is usually to disperse and prefabricate the bridge deck components in batches and transport them under the bridge after erection, and disperse them on the bridge deck with a crane on the construction access road. On the ground, construction workers use transfer equipment or mobile tooling to scatter them in the area where the bridge deck is installed, and then use forklifts or mobile tooling to carry out installation operations, and finally carry out the construction process of wet joints and sealing, and finally complete the bridge deck components Protective finished product. The site of this method is scattered and the operation area is simple, resulting in large ...

AI Technical Summary

Problems solved by technology

The site of this method is scattered and the operation area is simple, resulting in large fluctuations in prefabricated quality, difficult construction management, and high component damage rate; decentralized transportation, distributed fabrics, a large number of transport vehicles and hoisting equipment are invested, resulting in construction costs. Increase, the human factor in the transportation and hoisting process is relatively large, and the components are vulnerable to damage, resulting in increased resource consumption, and it is not easy to manage, increasing the difficulty of construction organization and management; decentralized installation requires a large number of work areas, and a large amount of labor and equipment are invested , the installation process uses manual coordination equipment, the installation accuracy and quality control errors are relatively large, which greatly increases the investment of personnel and reduces the speed of construction work. security risks
