Plastic dowel in sleeper manufacturers tell you that due to the high speed of trains, high-speed railways must have the following characteristics in addition to sufficient buckle pressure, considerable elastic range and strong ability to maintain the gauge of the elastic parts of subway railway fasteners. Plastic dowel in sleeper manufacturers tell you that once the high-speed railway is opened, due to the high speed and density, track maintenance can only be carried out within a very short blockage point. This requires that the components of the fastener have sufficient strength and durability.
Plastic dowel in sleeper manufacturers tell you that the fasteners have good noise reduction and vibration reduction performance. With the increase of the train speed, the dynamic effect of the track increases sharply, so the subway railway fasteners are required to have good noise reduction and vibration reduction performance, that is, the fasteners are required to adopt better elastic buffer pads. Plastic dowel in sleeper manufacturers tell you that in order to ensure the absolute safety of high-speed railway driving, the fasteners are required to have good insulation performance, and there should be sufficient impedance between the two strands of rails to ensure the normal operation of the track circuit. The plastic dowel in sleeper manufacturer tells you that the boltless type III fastener has few parts and is easy to install and disassemble. From a long-term point of view, it can greatly reduce the maintenance and repair costs. The elastic strip subway railway fasteners must use plastic casing instead of sulfur anchoring to meet the requirements of high-speed railway ballasted tracks; and the structure of the elastic strip type II fasteners, the bolts are bent, and the plastic casing does not enter water and dirt. It is easy to solve; in order to prevent the bolts from rusting, other protective measures should be taken. The elastic type III fasteners do not have these problems.
