Description of Subway DT Series Fastening
In recent decades, with the acceleration of population flowing in China, large and medium-sized cities to speed up the construction of urban rail. Relatively high speed railway, the requirement of the urban rail is relatively low, so it can be designed on the basis of high speed railway track structure for urban rail transport, this gives the designer the design of large space;Each city urban rail structure more or less differences. Especially fastening system is various, even in the same line also exist different fastening systems.Because Chinese fastening system in the subway is various, not a fixed is widely used fastening system;This paper, the DT series fastening in subway system has carried on the simple summary. Make a reference for fastening researchers.
