[0002] At present, the continuous beam triangular bracket is the main load-bearing component for the construction of the continuous beam 0# block. The traditional construction methods are mainly the following three types:

[0003] 1. Pre-embed large steel shear pins on the pier as support;

[0004] 2. Reserve holes in the pier body, weld large steel sections on the triangular bracket, and insert the steel sections into the reserved holes in the pier body as support;
