ZHU WEN / DU YI / MA BIN / LIU TINGTING / JING TAOHONG

The invention relates to a bridge support pre-pressing construction structure which comprises a rack and a loading table, a lifting frame is slidably arranged on the rack in the vertical direction, a supporting frame is slidably arranged on the lifting frame in the horizontal direction, and a lifting assembly used for driving the lifting frame to ascend and descend is arranged on the rack. A first driving assembly used for driving the supporting frame to slide is arranged on the lifting frame, and the loading table is hung on the supporting frame; a counterweight cavity is formed in the loading platform, a sand inlet and a sand outlet which are communicated with the counterweight cavity are formed in the loading platform, and a valve for closing the sand outlet is arranged on the loading platform; a counterweight table is arranged on the top wall of the loading table, a compression roller is rotationally arranged on the counterweight table, the compression roller is in rolling connection with the loading table, and a transmission assembly used for driving the counterweight table to move on the loading table is arranged on the loading table. The method has the effect of reducing the influence of the transverse load of the construction load on the stability of the bridge support.
