| Abstract: | The No.42 CNTT Plate-type Switch is made up of a switch,a connective section and some frogs.With the characteristics of allowing high-speed passage,being high in safety,etc.,the linearity of the switch is of the multi-curve linearity.With the laying construction of the No.42 CNTT Plate-type Switch at the Xuzhou East Station of the Beijing-Shanghai High-speed Railway as a practical example,the construction processes for laying the switch,the rail-welding and fine-rail-adjustment methods are introduced in the paper,which may serve as a good reference for the construction of other similar projects in the future. |
