In an implementation scene, the support object is a 2H900 multiplied by 300 section steel track, the power mechanism 3 is a hydraulic jack, and pushing construction of the steel box girder is performed. When pushing construction, after the steel box girder is transported to the site, the steel box girder is put on a 2H900 multiplied by 300 steel rail in advance, and is put on the steel box girder. And placing the pushing device on the track, pushing the pushing device forward to ensure that a hydraulic jack of the pushing device is in forced contact with the profile steel cushion block, and buckling a fixing assembly to fix the pushing device and the track together. And starting the hydraulic jack, and enabling the profile steel cushion block to slide forwards under the action of the jack, and simultaneously driving the steel box girder on the profile steel cushion block to move along with the profile steel cushion block. When the jack reaches the maximum stroke, the jack is jacked to restore according to the progress, and then the fixing component is lifted, so that the trolley is pushed to the condition that the jack is in forced contact with the profile steel cushion block. The operation is repeated until the steel box girder slides to the design position.
