[0002] Track fasteners are an important part of the railway track system. They are used to fix the track on the sleeper to ensure the stability and safety of the track. Uneven settlement of the rail transit civil structure is a common disease in engineering. The size of the uneven settlement is affected by engineering geological conditions, construction technology, construction quality and other aspects. The uneven settlement of the civil structure causes the track to be uneven, which may seriously affect the driving safety when it is serious. When the uneven settlement is small, it can be solved by adjusting the height of the track fastener. At present, the maximum height adjustment amount of commonly used fasteners is generally 30 - 40 mm.
