Truss Overhead Crossing Design of Liuhua Pipeline Section for Sebei-Xi'ning-Lanzhou Gas Pipeline

Liuhua pipeline section, a branch gas pipeline of Sebei Xi'ning-Lanzhou Gas Pipeline, is designed and constructed with the truss overhead crossing method. This truss overhead crossing structure is characterized by economic and simple in structure and clear arid distinct in force's transfer in its structure itself. The saving of project investment is remarkable with this crossing structure in Liuhua pipelme section.
