A guide beam comprises a guide beam upper chord and a guide beam lower chord, a hydraulic jack is arranged on one side of the guide beam upper chord, and supporting section steel is arranged on one side of the guide beam lower chord. One end of an oil cylinder of the jack is hinged to the guide beam upper chord through a rotating pin, one end of the supporting profile steel is hinged to the guidebeam lower chord through a rotating pin, and an upper lifting column of the jack is hinged to the other end of the supporting profile steel. The angle between the supporting profile steel and the lower chord of the guide beam is changed by shortening the exposed length of the hydraulic jack lifting column, and then the relative height of the bottom face of the front end of the supporting profile steel is increased. The supporting section steel extrudes the top of the supporting pier to generate counter-acting force by extending the lifting column, and then the bottom face of the lower chord ofthe guide beam is lifted to the higher position of the top face of the supporting pier. According to the utility model, the process of adjusting the height of the front end of the pushing guide beamis quicker and more effective, the time for adjusting the pier height on the guide beam is shortened, the pushing time is further shortened, and the safety and stability of pushing the precast beam and the front guide beam are improved.
