Rail traffic parking lot throat area arrangement structure

Abstract

The invention discloses a rail traffic parking lot throat area rail arrangement structure used for connecting each parking line arranged close to a rail main line in a parking lot with a parking lot incoming and outgoing line. One rail close to the rail main line is arranged as a throat area reference line in the throat area rail arrangement structure, and an interval between the reference line and the rail main line is maintained basically unchanged; while other rails in the throat area rail arrangement structure extend and approach a same side of the reference line respectively through turnouts to be gathered and connected on the reference line, and in this way, a connecting point gathering at the tail end of the reference line is formed in a throat area; the connecting point is connected with the incoming and outgoing line so as to realize connection between the parking lot parking lines and the rail main line. Aiming at the circumstance that the incoming and outgoing line is too long and cuts a land plot, thereby causing land resource waste in the prior art, a form that the throat area is arranged close to the rail main line is adopted, so that length of the incoming line and the outgoing line can be reduced effectively, and the land resource waste is avoided.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and in particular relates to an arrangement structure of a throat area of ​​a rail transit parking lot. Background technique [0002] The subway vehicle base is the logistics base to ensure the normal operation of the subway, and it is an important part of the subway system engineering. The vehicle base includes the depot and the parking lot. The main function of the parking lot is to undertake the train inspection and parking operations of subway trains, and can undertake biweekly and three-month inspection and temporary repair operations when necessary. In order to ensure passenger flow and relieve urban traffic pressure, rail transit stations are mostly located in central urban areas. Land for urban construction is expensive, and there are many existing buildings and pipelines. It is extravagant to choose more than ten hectares of land, and there are also many surrounding restrictions. In o...
