Segmented field line structure and construction method

Abstract

This invention relates to the field of subway construction technology, and discloses a depot track structure and construction method. The depot structure includes a track distribution section and a depot storage section, connected by a transition section. The track distribution section, depot storage section, and transition section can all be straight or curved, and also include a straight turnout section. The depot storage section comprises two units, each including a first-level depot and a second-level depot located directly above the first-level depot. The track distribution section includes two parallel outer tracks and two inner tracks positioned between the two outer tracks. The two inner tracks are connected by a crossover, and the outer tracks are connected to the inner tracks by a single crossover. One end of each inner track leading to the main track is connected to an exit track and an entry track, respectively. The end of the outer track away from the transition section is connected to a turnaround track. This invention can significantly reduce the land area occupied by the depot, reduce the area of ​​building demolition and earthwork, and lower the construction difficulty and project investment.
