Problems solved by technology
[0003] However, when the existing crane directly rolls the bridge segment on the ground, since the bridge segment directly touches the ground, during the lifting process, the bridge segment will exert a large pressure on the contacting ground, making the bridge segment The bridge segment is deformed due to extrusion on the side contacting the ground, which makes the quality stability of the bridge segment poor

Embodiment Construction
[0023] The invention provides a method for overturning a bridge segment, which can reduce the probability of deformation of the bridge segment due to extrusion during the overturning process, so that the quality stability of the bridge segment can be improved.
[0024] An embodiment of the present application provides a method for overturning a bridge segment, the method comprising the following steps:
[0025] Step S1: setting a reinforcement structure on the first side of the bridge segment;
[0026] Step S2: selecting a rotating shaft, and fixing one end of the rotating shaft to the strengthening structure;
[0027] Step S3: Select a support, and set the other end of the rotating shaft on the support;
[0028] Step S4: lifting the bridge segment by a crane, turning the upper surface of the bridge segment from a horizontal direction to a vertical direction, wherein the crane is connected to the second side of the bridge segment, and The second side is adjacent to the first...

The invention discloses an overturning method of a bridge segment. A reinforcement structure is arranged on a first side face of the ridge segment; a rotation shaft is selected, and one end of the rotation shaft is fixedly connected to the reinforcement structure; a support is selected, and the other end of the rotation shaft is arranged on the support; the ridge segment is lifted by a crane; the upper surface of the ridge segment is overturned to the vertical direction from the horizontal direction, wherein the crane is connected with a second side face of the ridge segment, and the second side face is adjacent to the first side face. By adopting the overturning method of the bridge segment, the probability of deformation of the bridge segment caused by extrusion during the overturning process can be lowered, and the quality stability of the bridge segment can be improved.
Description
technical field [0001] The invention relates to the technical field of bridge manufacturing, in particular to an overturning method for bridge segments. Background technique [0002] The existing overturning method of the bridge segment usually uses a crane to directly roll the bridge segment on the ground, wherein one end of the bridge segment is in contact with the ground, so that the crane only needs half the weight of the bridge segment to lift. The weight makes it easier for the crane to turn the bridge section over. [0003] However, when the existing crane directly rolls the bridge segment on the ground, since the bridge segment directly touches the ground, during the lifting process, the bridge segment will exert a large pressure on the contacting ground, making the bridge segment The bridge segment is deformed due to extrusion on the side contacting the ground, which makes the stability of the quality of the bridge segment poor.
