The invention discloses a method for truss concrete injection construction. The method comprises the steps of collecting building requirements and designing a steel box bidirectional truss structure; applying finite element software to establish a structure model of a truss, and a lower layer building and an upper layer building which are connected with the truss; using the finite element software to perform mechanics checking on the model, and calculating a pressure value of the truss; simulating reinforcement after concrete injection into a high pressed section with the high pressure value of the truss; manufacturing the truss according to the model; and performing site construction. Through deep design, internal force of the truss is analyzed by application of the finite element software, a local internal concrete filling mode is adopted for the high pressed section of a chord member, so that the strength and stiffness of the truss are enhanced, and the bearing capacity of the transfer truss is improved.
