Abstract
This paper makes an in-depth analysis on the design of the super large-scale maintenance workshop for Beijing-Shenyang Passenger High-speed Rail maintenance workshop of Beijing-Shenyang Passenger High-Speed Rail, and demonstrates its important position in industrial architecture referring to the significant status of Beijing-Shenyang Passenger High-speed Rail in China's railway construction. Through the study on the design process of architecture, structure and construction of the maintenance workshop, and the research on the fireproof performance, this thesis provides a useful reference value and academic significance for the design and construction of the super large maintenance workshop for high-speed rail in China.
Highlights
Introduction of Fireproof DesignWhen analyzing fireproof issue, the aim of "fireproof design plan [5] "is to guarantee the following situations: first, the prevention of fire; two, find fire in time; three, sensitive trigger alarm system; four, orderly evacuation of personnel; five, control and elimination of fire
Fire extinguishing system is installed in maintenance workshop, according to the “code fireproof code for architectural design” (GB 50016-2014) [4] maximum fireproof zone should be controlled within the range of 16,000 m2, and the safe evacuation length is 80.0m
When the requirements of "Fireproof Code of Architecture Design [6]" cannot be meet by "design plan of fireproof", problems will be divided into several technical plan modules, which can ensure the safety of personnel evacuation and control the fire, and the losses will be reduced to a minimum and the safety of the structure can be quaranteed [7]
Summary
Beijing-Shenyang Passenger High-speed Rail (“Rail” in short below) is one of the important rails on building. In the future, it will undertake main passenger distribution function between Bohai economic zone and the northeast industrial base and become transportation links in North China, East China, South China and Northeast Economic Zone. The Rail dedicated line is an important part of the "four vertical and four horizontal [1]" (Railway Planning) network China, and will become the important traffic artery connecting Shanhaiguan and abroad Based on such an important high-speed railway project, large maintenance facilities are very important. 69 Zhang Jialu et al.: A Study on the Design of Xinghuo Maintenance Workshop for Beijing-Shenyang Passenger High-speed Rail space is divided into three spans: 33.0m+33.0m+18.0m, each same time. The span of" lines" maintenance workshop is divided into three spans, within which the adjacent track spacing is 8.5m and 7.0m, and the net spacing between track and structural column is 5.0 m.
