And supporting beam steel bars and lattice steel columns in deep foundation pit are connected through steel sleeves

The utility model provides a structure for connecting supporting beam steel bars and lattice steel columns in a deep foundation pit through steel sleeves. The structure comprises the lattice steel columns and the inner supporting beam steel bars. The lattice steel column is provided with four pieces of angle steel and a plurality of batten plates. The supporting beam steel bars are connected withthe lattice steel columns in a crossed mode, and particularly, the supporting beam steel bars further comprise a plurality of steel sleeves which are of straight-through tubular structures with threads on the inner walls. The steel sleeves are longitudinally arranged and symmetrically distributed on the two sides of the lattice steel column, and one ends of the steel sleeves are connected with batten plates of the lattice steel column in a welded mode. The supporting beam steel bars are symmetrically distributed on the two sides of the latticed steel column, outer wall threads are arranged onthe outer walls of the end
