Description

Technical Field

[0001] This application relates to the field of continuous settlement detection technology, and in particular to a device for continuously detecting preload settlement. Background Technology

[0002] Continuous beams (especially those constructed using cast-in-place scaffolding) are critical bridge components spanning multiple piers and possessing strong structural integrity. Their construction quality directly impacts the safety and performance of the completed bridge. Before pouring concrete for the continuous beam, a settlement pre-stress test must be conducted on the support system composed of the scaffolding and the foundation. This test simulates subsequent construction loads by loading objects equal to or exceeding the actual weight of the beam (such as water bags, sandbags, and reinforcing bars), monitoring the settlement and deformation values ​​at key points of the scaffolding and foundation. On one hand, this allows the support system to complete most of its inelastic and elastic deformations in advance, laying the foundation for precise control of the beam's alignment (elevation and slope) and ensuring the quality of the completed bridge during the formal pouring. On the other hand, it verifies the safety of the support system, preventing collapse accidents. It is an indispensable and crucial procedure in the construction of continuous beams.

[0003] Existing continuous beam preload settlement detection methods largely rely on pre-embedded points combined with gauge rod observation. While the utility model patent CN206756142U discloses a detachable preload settlement observation device, including a settlement seat, a vertical measuring rod detachably connected by threads, and a detection device, it still fails to address the core shortcomings of existing technologies: First, settlement detection requires pre-embedded points, which are easily obscured by debris or unclear markings during construction, making positioning difficult and hindering successful detection. Second, the observation process requires technicians to repeatedly climb to designated locations on the support system to place the gauge rod, a cumbersome procedure with safety hazards. Third, the limited working space within the support system makes it difficult for technicians to ensure the gauge rod is perfectly vertical when manually placing it, leading to observation errors due to gauge rod tilt, thus affecting the accuracy of settlement data. This fails to provide a reliable basis for assessing the safety of the support system and controlling the beam's alignment, thus limiting the efficiency and accuracy of preload settlement testing. Utility Model Content

[0004] The purpose of this utility model is to provide a device for continuous detection of preload settlement, which solves the problems of existing continuous beam preload settlement detection which requires the reservation of pre-embedded points, which may be covered due to unclear markings; existing settlement detection requires technicians to repeatedly climb and place the leveling rod, which is very cumbersome; and the technicians place the leveling rod in a limited space, which inevitably leads to errors due to the leveling rod not being horizontal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for continuously detecting pre-compression settlement, comprising a gauge and a buckle, wherein the gauge and the buckle are in contact with each other, the gauge includes a rotating base, the surface of the rotating base is provided with a second groove, the upper end of the rotating base is fixedly connected to a telescopic caliper, the surface of the telescopic caliper is provided with a wind tunnel, and the front of the telescopic caliper is provided with a scale.

[0010] Preferably, a level is provided at the upper end of the buckle plate. By setting the level, it is ensured that the buckle is in a horizontal state after installation, thus reducing measurement errors.

[0011] Preferably, the mounting holes of the buckle plate are assembled with the rotating base, and the first buckle and the second buckle engage with each other. Through the cooperation of the first buckle, the second buckle, the buckle plate and other structures, the installation stability of the tower gauge can be guaranteed.
