Line rail symmetric three-throw turnout in urban rail traffic engineering

Abstract

The invention provides a symmetric turnout for line rails No.4 and No.5 in urban rail traffic engineering. The turnout is arranged on a parking line rail of an underground line in an urban rail engineering, the structure of the symmetric turnout comprises a group of railroad switches, a group of frogs and a connecting steel rail, wherein the railroad switches are connected with the frogs by virtue of the connecting steel rail so as to form a symmetric turnout provided with two side rails. The symmetric turnout provided by the invention has the beneficial effects that the turnout ensures a subway and a light rail vehicle to travel safely between a main line and a parking line, related technical standards and safety requirements of the urban rail engineering are met, and the advantages of safety, reliability and convenience in manufacturing, paving, construction and maintenance are realized. By applying the symmetric turnout provided by the invention, turnout investment can be saved, and length of an auxiliary line can be obviously shortened, thus investment of a building project is greatly saved, construction difficulty is reduced, and project risk is reduced.

Description

technical field [0001] The invention relates to a symmetrical three-way turnout for an urban rail transit engineering line track. Background technique [0002] Urban rail transit projects have developed rapidly in my country in recent years, and are mainly used for large-capacity urban passenger transportation, which is an effective means to improve traffic congestion in large cities. [0003] The problem of traffic congestion in my country's big cities is becoming more and more serious, and urban rail transit is being built one after another, such as Beijing, Shanghai, Guangzhou, Shenzhen, etc., which have begun to take shape. Some medium-sized cities such as Qingdao, Ningbo and Suzhou are under construction. Because each city independently raises funds, builds and manages independently, and lacks systematic research and development and unified management, some systems and equipment have problems that need to be improved and perfected. [0004] In the auxiliary line of ur...

AI Technical Summary

Problems solved by technology

The turnout is one of the important equipment of the track system. The traditional connection type is to use a common single-opening turnout. The disadvantage is that the line in the turnout area is long, the number of turnouts is large, the investment in civil engineering is also large, and the project implementation is difficult.
