Background
The box girder is applied with prestress, so that the load generated by positive and negative bending moments and the dead weight of the box girder can be reduced or offset, the bearing capacity of the box girder is improved, and the application of the prestress on the box girder can be realized by stretching and drawing the steel strand penetrating through the prestressed duct on the box girder. When the prefabricated box girder is constructed, a prestressed pore channel is formed by penetrating and pulling the rubber tube on the box girder, specifically, when a steel reinforcement framework of a box girder body is bound, the binding of the designed positioning net and the steel reinforcement framework are performed according to the prestressed pore channel, then, the tube penetrating is performed according to the position of the positioning net, after the tube penetrating is completed, concrete is poured, after the concrete reaches a certain strength, the rubber tube is pulled out again, and the prestressed pore channel can be formed on the box girder. The rubber tube needs to be ensured to be accurately positioned by the positioning net when penetrating into the positioning net, if the positioning net deviates, the deviation amount needs to be controlled within 4mm, and the rubber tube is flat and straight in the box girder. When the pipe is drawn out, cement paste cannot be attached to the rubber pipe required to be drawn out, the wall of the formed prestressed duct is smooth, and no residue is left.
