Abstract: In the traditional gas storage construction, due to the effect of on-site construction environment, it is difficult to control the project quality and the construction progress, and the risk of safety management is high, thus the urgent needs of the project owner for the construction period is hard to be satisfied. In order to improve the construction quality of gas storage, shorten the construction period and reduce the safety risk, modularization technology was adopted for the division of module units, comparison of road transportation schemes, three-dimensional design of modules and analysis on structural stability. At the same time, the modules were processed, manufactured, tested and packaged in the prefabrication plant, and then were assembled on site according to the reassembly scheme upon arrival, so as to realize the rapid completion and commissioning of gas storage. The results indicate that the construction mode with modularization technology can minimize the impact of on-site adverse factors on construction quality and progress. Moreover, the safety risk of the project site is reduced and the construction period is shortened due to the transfer of a large number of construction operations to the prefabrication plant. The research results could provide design ideas for the gas storage projects to be constructed in modular mode.
