This work includes the site selection, design, construction, maintenance, and subsequent inspection of bridges, aiming to ensure the safety, economy, and aesthetics of the bridges. The bridge sill is a key component of the bridge structure. It is usually located on top of the abutments or piers and is closely connected to the bearings. The main function of the sill is to ensure that the bearings can stably support the bridge superstructure, transmit and distribute the loads from the superstructure to the piers, and thus maintain the overall stability and safety of the bridge.

[0003] The main purpose of the anchor holes reserved in the pad stone is to reserve holes for the installation of anchor bolts (such as anchor bolts) in advance when the pad stone is poured, so that the anchor bolts can be accurately and firmly installed in the designated position in the subsequent construction, thereby achieving stable installation of equipment, supports, etc. In order to conveniently reserve anchor holes during the pouring process of the bridge pad stone, a comprehensive positioning device for the anchor holes reserved in the pad stone is required.

[0004] The location of anchor holes in bridge bearings is a highly technical area of ​​bridge engineering, with strict requirements placed on their size, elevation, position, and depth. Currently, most reserved anchor holes are prepared using the "buried pile method," which involves fixing a pile (or wooden box) at the designed anchor hole location. Once the concrete reaches a certain strength, the pile is removed to create the reserved hole. This method is cumbersome and prone to misalignment, and the reserved hole placement is not precise, resulting in unstable bearing installation. To address this issue, a comprehensive positioning device for reserved anchor holes in pad stones has been proposed. Utility Model Content

The outer circumference of the bidirectional threaded rod 4 is threadedly connected to the positioning slider 3, rotate the two-way threaded rod 4, the two-way threaded rod 4 will drive the two groups of positioning sliders 3 to move toward or relative to each other, the outside of the two-way threaded rod 4 is fixedly connected with a rotating handle 5 for easy rotation, the outer periphery of the two-way threaded rod 4 is rotatably connected to the inside of the positioning frame 1, and the inside of the positioning slider 3 is fixedly connected with a positioning rod 6. The positioning rod 6 is provided with two groups, and the two groups of positioning rods 6 are symmetrically arranged on the inside of the positioning slider 3. At the same time, the positioning rod 6 connects the two groups of positioning grooves 2 symmetrically arranged. A sliding groove 7 is provided at the top of the positioning rod 6, and a sliding cylinder 8 is slidably connected inside the sliding groove 7. The sliding groove 7 limits the sliding cylinder 8 to slide back and forth only along the inner wall of the sliding groove 7. A fixing component is fixedly connected to the inside of the sliding cylinder 8. The fixing component is used to clamp and fix a columnar object. The inside of the fixing component is in contact with a positioning column 17. The positioning column 17 is made of PVC.

The reserved anchor hole is also relatively symmetrical, which is convenient for fixing the support. When you want to conveniently adjust the depth of the reserved anchor hole, slide the sliding column 15 along the rounded groove 16. The sliding column 15 drives the threaded extrusion block 11 to move to both sides along the thread groove 10, loosen the clamping ring 12, and then adjust the depth of the positioning column 17 inside the clamping ring 12. Then slide the sliding column 15 to the other side along the rounded groove 16. The threaded extrusion block 11 moves toward the middle, tightening the clamping ring 12 inward and fixing the positioning column 17, thereby conveniently adjusting the depth of the reserved anchor hole.
