Sanbo undertakes the production of curved beams and straight beams in this project.

Track beam is mainly divided into vehicle base simply supported beam, main line simply supported beam, main line continuous rigid frame beam, each type is divided into straight beam and curve beam. Due to the superposition of different parameters such as beam length, horizontal curve, vertical curve, superelevation value and pre-camber, there are no two identical beams. The concrete of PC track beam is not allowed to be repaired and painted, and the top and side surfaces of the formed beam body are the channels for tires to travel. Unlike traditional precast beams, it is impossible to adjust a certain size through the pavement layer.

Features of track beam:
1. The beam type space varies, and each beam is different;
2. The cross-sectional dimension has high accuracy, and the accuracy is measured in millimeters;
3, linear secondary design is difficult, need to prepare a one-to-one work instruction;
4, the production line configuration is complex.
