1, the nozzle should be reinforced at the cross section of the chord of the pipe truss to avoid damage and deformation during transportation, and the accuracy of the interface must be guaranteed to avoid staggered joints. A guide plate is arranged at the butt joint of the nozzle to facilitate accurate alignment of the nozzle, and the assembled nozzle needs to be polished into a smooth transition after welding.

2. When welding and assembling, we must pay attention to the sequence of assembly and welding, strictly implement the process, and ensure the geometric measurement of components.

3. The survey work should keep up with it in time, carry out tracking measurement, observe the settlement of jig and bearing scaffold in time, adjust the elevation of truss nodes, make the elevation and axis of truss meet the design requirements, and ensure the assembly quality of truss.

4. Because the truss assembly work belongs to aerial work construction, there is a certain danger, so safety railings should be set on the scaffolding to ensure the safety of the operators.
