At present, modern tramway turnouts in foreign developed countries have formed a series of products. With the rapid development of modern tramways in my country in recent years, the tramway turnouts of domestic turnout manufacturers are generally limited to single-track turnouts, which cannot be applied to road traffic. Busy areas with complex foundation pipelines and extremely difficult construction and installation

The invention discloses a modern tramcar 60 R2 groove profile rail double-line three-opening combined turnout. The turnout assembly comprises an uplink three-opening turnout and a downlink three-opening turnout; the uplink three-opening turnout and the downlink three-opening turnout both comprise a straight rail, a left rail and a right rail, and a 60 R2 groove profile rail is adopted for the straight rail, the left rail and the right rail; and the double-line three-opening combined turnout comprises a first trip switch area, a second trip switch area, a compound frog area, an intermediate diamond area and a tail diamond area. According to the modern tramcar 60 R2 groove profile rail double-line three-opening combined turnout in the invention, the structural form of the double-line three-opening combined turnout is proposed for the first time, five areas of the overall structure are formed in a limited field, the guiding problem of respective three directions of the uplink line and thedownlink line is solved, and the double-line three-opening combined turnout is particularly suitable for road segments with busy road traffic and complex basic pipelines; and for the construction method, a CP III measurement technology is successfully adopted, the construction precision of the urban modern tramcar turnout is improved to a high-speed rail standard, and typical guiding significanceis provided for wire net setting of the modern tramcars in the future.
Description
technical field [0001] The invention belongs to the field of modern tramway turnouts, and in particular relates to a modern tramway 60R2 grooved rail double-track triple-opening combination turnout and a construction method thereof. Background technique [0002] In recent years, modern trams have become one of the important directions of urban transportation development due to their characteristics of energy saving, environmental protection, small investment, moderate passenger capacity, comfortable rides, high degree of industrial correlation, strong ability to absorb employment, and great development potential. . In this context, the formation of a modern tramway network is imperative, and special turnout types are one of the factors restricting the formation of the network. At present, modern tramway turnouts in foreign developed countries have formed a series of products. With the rapid development of modern tramways in my country in recent years, the tramway turnouts o...
