A coupling device for a supporting beam of an earth retaining wall, according to the present invention, enables the easy coupling of a supporting beam while maintaining the rigidity of the supporting beam by eliminating a coupling hole, which is bored in the supporting beam when the supporting beam for reinforcing an earth retaining wall in a construction site is coupled to a wale and a support beam. The coupling device for a supporting beam of an earth retaining wall comprises: a first coupling plate; a second coupling plate which is coupled to the first coupling plate; a third coupling plate which is coupled to the first coupling plate; a first coupler which couples the joint ends of first and second supporting beams to each other; a second coupler which is fixed to a wale to support the left and right sides of the third coupling plate; and a clamp which fixes the first and second supporting beams and a support beam to each other. |
