Technical Field
[0001] The utility model relates to the technical field of cable bridges, in particular to a vertical tee at the lower corner of a high-strength trough-type bridge. Background Art
[0002] Tray-type bridge is one of the most widely used bridges. However, when laying cables, it is often necessary to gather and change the direction of cables, so a three-way bridge is needed. When laying cables in the prior art, when the cables pass through the traditional vertical three-way at the lower corner, because the bending part is a right-angle structure, the cables on the upper and lower ends must also be bent into right angles to gather together and change the laying direction, which can easily cause the wires inside the cable to break. At the same time, the edges of the right-angle surface at the bending part rub against the cables, which can easily cause cable wear, affecting the safety of the cables after laying to a certain extent.
