1. Ordinary Coach screw spike has a triangular shape and is used to connect or fasten parts. Ordinary Coach screw spikes are divided into coarse and fine-tooth Coach screw spikes according to the pitch. The connection strength of fine-tooth Coach screw spikes is higher.
2. The shape of the transmission Coach screw spike has trapezoidal, rectangular, saw-shaped and triangular.
3. Sealed Coach screw spike is used for sealing connection, mainly for tube coach screw spike, cone coach screw spike and cone tube coach screw spike.
At the same time, the influence of the deformation of the lower part of the mansion and the structural strength are checked. The base adopts a reinforced concrete structure, and the concrete strength level is 0. The external dimensions of the base are determined according to the design load calculation. The thickness of the inner side of the base of the curved section shall not be less than 100mm. (s) The convex block is designed according to the cantilever member fixed on the concrete base, and the shape is divided into circular and semicircular. The resin material is filled between the convex stop and the track plate, and the design thickness is 40mm. The filling resin should be constructed by the bag filling method. Its performance should comply with relevant regulations. The curve superelevation is set on the base, and the superelevation setting is based on the top surface of the inner rail. The outer rail elevation method is adopted, and the linear transition is within the range of the transition curve. The top surface of the base outside the track slab is equipped with a horizontal drainage slope. The CRTS1 slab ballastless track of the 3-way base section is set on the surface of the subgrade bed.
