1. A container detecting system, comprising:

  • a horizontal accelerator for emitting radiation,a vertical accelerator for emitting radiation,a gantry tower composed of a first vertical girder, a second vertical girder, an upper cross girder, and a lower cross girder, and defining a scanning channel,a horizontal collimator disposed in front of the horizontal accelerator, and having a slit from which radiation is emitted to define a first plane of radiation,a vertical collimator disposed in front of the vertical accelerator, and having a slit from which radiation is emitted to define a second plane of radiation that is parallel with the first plane of radiation,a vertical collimation column for providing therein the horizontal collimator, and being fixed to the first vertical girder,a horizontal collimation girder for providing therein the vertical collimator, and being fixed to the upper cross girder,a double-detector arm mounted in the second vertical girder of the gantry tower, comprising a plurality of detector modules for receiving the first and second planes of radiation, the plurality of detector modules comprising a first horizontal beam detector module for receiving the first plane of radiation, and a first vertical beam detector module for receiving the second plane of radiation,a second horizontal beam detector module for receiving the first plane of radiation,a second vertical beam detector module for receiving the second plane of radiation, anda supporting seat on a bottom surface, wherein a lower surface of the lower cross girder of the gantry tower is fixed with the supporting seat, a first end and a second -end of the lower cross girder is connected to the first vertical girder and to the second vertical girder, and a bearing plate is disposed on an upper surface of the lower cross girder for allowing a container truck to pass through the scanning channel.
