AI Technical Summary
In the existing technology, when two symmetrical conical hoppers are used for track paving, the concrete pouring is uneven, which can easily lead to overflow on one side or cavities on the other side. In addition, the conical hoppers can easily cause the concrete to vibrate and overflow, affecting the construction quality and efficiency.
The design employs an inverted "V"-shaped material distribution ramp and a symmetrical planar design within a silo, combined with flow sensor monitoring, to achieve uniform left-right distribution of concrete. Concrete baffles prevent overflow, and the rationally designed structure enhances stability.
This method achieves uniform pouring of concrete in the gap between the track slab and the track base plate, avoiding overflow and cavities, ensuring construction quality and site cleanliness, and improving construction efficiency.
