According to the construction requirements, the axial direction of the pre-buried pipe should be consistent with the direction of the prestressed tendons of the cable. However, in the actual construction process, affected by factors such as installation accuracy, there may be a certain deviation between the pre-buried pipe and the prestressed tendons of the cable, and the slope deviation of each pre-buried pipe and the prestressed tendons is not completely consistent.

[0003] During the construction of the cable-stayed bridge, it is necessary to install shock absorbers between the embedded pipes and the prestressed tendons to prevent the long-term fatigue vibration of the components from damaging the cable anchoring system during the later service period of the bridge. If the shock absorber fails due to fatigue, the installation space dimensions need to be accurately measured during the repair process.

When using conventional measuring tools to measure the inner diameter, it is affected by the obstruction, the operation is inconvenient and the measurement is inaccurate; if a soft ruler is used to measure the size of the annular space, there are defects such as inaccurate measurement and large error values. Therefore, a measuring tool for repairing a cable-stayed shock absorber is proposed, which is suitable for measuring the inner diameter of the annular space of the embedded pipe during the repair work of the cable-stayed shock absorber, as well as the inner diameter measurement of the same type of annular structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 In the embodiment of the utility model, a measuring tool for repairing a cable-stayed shock absorber includes an arc-shaped bracket 4, which is made of a steel structure and is not easily deformed. A positioning member and a measuring member are respectively arranged at the two ends of the arc-shaped bracket 4. The measuring member includes a scale 6 and a measuring pointer 7 arranged in parallel. The scale 6 and the measuring pointer 7 are both movably connected to the arc-shaped bracket 4.

Further, the setting of the fastening nut 2 and the adjusting nut 3 can limit the position of the threaded rod body 1-2, thereby avoiding loosening of the threaded rod body 1-2 during the measurement process, which ultimately leads to errors in the measurement results. At the same time, the positioning pointer 1 is movably connected to the arc bracket 4, and the adjusting bolt 3 and the fastening bolt 2 are cooperated to appropriately move the adjusting bolt 3 axially to achieve fine-tuning of the accuracy of the tooling scale 6.
