The invention relates to the field of gas-steam combined cycle generator sets, and discloses a plant layout structure applied to four pipelines of a single-shaft gas turbine. The device comprises a base, a lubricating oil tank, a single-shaft gas-steam combined cycle generator set, a main steam pipeline, a high-temperature reheating steam pipeline, a low-temperature reheating pipeline, a low-pressure steam pipeline, a high-pressure main steam valve, a low-pressure main steam valve, a reheating main steam valve and a lubricating oil pipeline. According to the embodiment of the invention, the arrangement lengths of the main steam pipeline, the high-temperature reheating steam pipeline, the low-temperature reheating pipeline and the low-pressure steam pipeline can be reduced, the number of elbows is reduced, the pressure drop is small, the system efficiency is improved, and the construction cost is saved. Besides, the oil pipeline is fully isolated from the main steam pipeline, the high-temperature ...
