Abstract
The invention discloses a buckle anchor cable force sensing and temperature linear control compensation device and a construction method. The buckle anchor cable force sensing and temperature linear control compensation device comprises a buckle anchor cable, an anchor plate, a power supply and a controller; the buckle anchor cable comprises a steel strand and an electric heating wire, and the steel strand and the electric heating wire are arranged through thermal conductivity; the anchor plate is used for making the buckle anchor cable fixedly installed on a main arch rib of an arch bridge and a buckle tower, and the electric heating wire is arranged to be insulated to the anchor plate; the positive pole and the negative pole of the power supply are electrically connected with the two ends of the electric heating wire respectively; the controller is used for controlling connection of the power supply and the electric heating wire and heating the steel strand to the preset temperatureso as to fix the buckle anchor cable to the anchor plate at the preset temperature, so that the buckle anchor cable is fixed to the needed linear range from the buckle cable deformation position to closure of the arch bridge main arch rib at the preset temperature. According to the technical scheme, the problem that an existing arch bridge cable hoisting and buckling construction method has difficulty in the scheme of implementing cable release to reduce the cable force, so that a large linear error is caused in the closing process is solved.
Description
technical field [0001] The invention relates to the technical field of bridges, in particular to a buckle and anchor cable force sensing and temperature linear control compensation device and a construction method. Background technique [0002] In the construction process of arch bridge cable hoisting, it is easier to tension the buckle anchor cable than to release it. Generally, the buckle anchor cable made of steel strands is used to pull the arch rib segment by anchor and clip for hoisting. It is to increase the force of the buckle anchor cable, tighten the hoisting and the installed section, and make it stable. However, when the alignment of the arch rib deviates from the preset alignment, it is necessary to adjust the cable force of the fastening anchor cable, supplement the tension to increase the cable force, and release the tension to reduce the cable force. When the buckle anchor cable needs to be released, the clip in the anchor must first be taken out, which has ...
