The utility model provides a kind of anti-maze flow terminal full embedding's ballast structure, it is related to rail transit ballast technical field, including concrete layer;Reinforcing mesh is set in concrete layer, reinforcing mesh and concrete layer are jointly structured as ballast body, the top of concrete layer is provided with mounting hole, mounting hole extends to with reinforcing mesh;Anti-maze flow terminal is set in mounting hole, the top surface of anti-maze flow terminal is flush with the surface of concrete layer, anti-maze flow terminal is suitable for connecting reinforcing mesh with electric connection piece.According to the ballast structure of the utility model, by setting mounting hole on the top of concrete layer, and after anti-maze flow terminal is set in mounting hole, the top surface of anti-maze flow terminal is flush with the surface of concrete layer, avoid anti-maze flow terminal exposure, to avoid anti-maze flow terminal trip, to facilitate work personnel inspection and personnel evacuation under emergency.

This utility model belongs to the field of building door and window technology, specifically to a high-performance aluminum alloy system door, including a low threshold, a door frame, a door leaf, and glass. The low threshold includes an interior threshold profile and an exterior threshold profile. Each of the interior and exterior threshold profiles has a cavity. A thermal insulation strip connects the interior and exterior threshold profiles. The interior threshold profile is higher than the exterior threshold profile, and on the interior side of the interior threshold profile, it has a rounded corner and its upper surface slopes upwards to the other side. A threaded hole wall is provided in the inner cavity of the upper surface. The upper surface of the exterior threshold profile has anti-slip textures, and a threaded hole wall is also provided in the inner cavity of its upper surface. In this utility model, the structural design of the low threshold, through the natural transition between high and low slopes and the cross-sectional design of the double-layer sealing structure, avoids dust accumulation or tripping hazards at right-angle bends, while ensuring unobstructed passage for wheelchairs and strollers.
