Description

Technical Field

[0001] This utility model belongs to the field of track technology, specifically relating to a drainage-type ballastless track bed structure. Background Technology

[0002] Ballastless track refers to a track structure that uses an integral foundation of concrete and asphalt mixture to replace the loose crushed stone track bed. Ballastless track has the advantages of good smoothness, good stability, long service life, good durability, less maintenance work, and avoidance of splashed ballast.

[0003] However, current ballastless track structures have certain limitations. For example, Chinese Patent Publication No. CN210621348U discloses a novel ballastless track structure, including a base with at least one limiting boss and at least three lifting components; a precast track slab located above the base, with a limiting groove at the bottom of the precast track slab adapted to the limiting boss; and the top of the lifting components abutting against the bottom of the precast track slab. Using this technical solution, the ballastless track structure lacks an efficient drainage system. During heavy rain, the hourly rainfall may exceed the drainage rate of the ballastless track structure, leading to a large accumulation of water that cannot be quickly drained. This affects train operation on the ballastless track structure and can potentially cause derailment or similar safety accidents.

[0004] It is evident that the existing ballastless track structure lacks an efficient drainage system, resulting in a large amount of water accumulating inside the ballastless track structure that cannot be drained quickly. This affects train operation on the ballastless track structure and can lead to safety accidents such as train derailments. Utility Model Content
