苏通GIL综合管廊工程GIL管道专用运输机具研发

Research and development of special transportation machines for GIL pipelines of Sutong GIL comprehensive pipe corridor

针对某特高压综合管廊过江输电项目,文中采用盾构管廊方式,管廊两侧分别设3相GIL输电管路,从江底穿长江主航道,两侧通过竖井和地面引接站与架空线路相连,在综合管廊路径长、走向复杂;内部作业空间受限,施工量大且工期紧的情况下,实现了采用过江管廊GIL的方式长距离输电。

Sutong GIL comprehensive pipe corridor is the first UHV GIL comprehensive pipe corridor which is an ultra-long distance GIL innovation project with the highest voltage level,the largest transmission capacity and the highest technical level.Shield pipe gallery is adopted.Three-phase GIL transmission lines are laid on both sides of the pipe gallery,passing through the main channel of the Yangtze River from the bottom of the river,and both sides are connected to overhead lines through vertical shafts and ground docking stations.With long path,complicated direction,limited internal working space,large work quantities and tight construction schedule in comprehensive pipe corridor,the first long-distance power transmission by using the GIL river-crossing pipe gallery in China was realized.
