Background Art

The bearing pad stone is set at the connection part between the abutment and pier top and the bearing, and is mostly cast on-site with concrete. The bearing pad stone has the unique characteristics of small concrete volume, large force, stress concentration, dense distribution of steel bars, and high construction precision requirements. The service life of the bearing is 10-20 years, because various damages may greatly shorten the service life, but the life of the bridge is 50 years for small and medium-sized bridges and 100 years for large bridges, which is much longer than the bearing, so the bearing must be replaced regularly. At this time, there is a bearing pad stone, which can make space when replacing the bearing and facilitate the placement of the jack. Before the construction of the bearing pad stone, the measurement and layout work should be done well to determine the plane position and elevation. After the construction of the bearing pad stone is completed, the usual detection method of the bearing anchor hole is to directly measure it with a steel ruler. This measurement method is more troublesome. First, it is necessary to measure whether the axis position of the anchor hole is correct, and then measure the size of the anchor hole, and it is necessary to measure the 4 anchor holes one by one. The measurement times are many and the accuracy is not high.

If all the aperture measurement components 30 can be successfully put in, then it can be preliminarily judged that the axial position of the anchor hole is qualified. In order to further confirm the size of the aperture, the hand-tightening nut 31 can be rotated. The rotation of the hand-tightening nut 31 will drive the transmission gear 33, the transmission screw 34, the planetary gear 355 and the sun gear 354 to work in conjunction in turn. In this process, the arc groove 35 on the sun gear 354 41 will move relative to the positioning anchor 3531, thereby driving the telescopic side plates 353 to expand outward. During the expansion process, these telescopic side plates 353 will pass through the movable hole 321 and finally tightly contact the inner wall of the anchor hole. Then the electronic sensor 3532 will immediately capture the relevant measurement data and display these data in real time on the display unit 11. By reading these readings, the aperture size of the anchor hole can be accurately known, thereby completing the positioning detection work of the anchor hole of the entire bridge support pad stone.
