Description

Technical Field

[0001] This utility model relates to the field of tie rod anchoring block technology, and in particular to a multi-directional stress monitoring tie rod anchoring block. Background Technology

[0002] Tie rod anchor blocks are a type of structure used in bridges to fix tie rods. As one of the main load-bearing components of an arch bridge, the stability of the tie rod is crucial to the overall safety of the bridge. The anchor blocks are connected to the main structure of the bridge through pre-embedded parts or post-anchoring methods to ensure that the tie rod can be firmly fixed in the predetermined position, thereby bearing various loads during the operation of the bridge.

[0003] The following problems exist: In traditional bridge construction, tie rod anchor blocks typically only have basic anchoring functions and lack multi-directional stress monitoring capabilities. This means that during construction, workers often cannot accurately determine whether the erected tie rods can achieve the expected stable effect. Due to the lack of real-time stress monitoring data, workers cannot understand the stress on the tie rods in different directions in a timely manner, thus failing to ensure their stability. In this situation, workers also cannot accurately assess the overall safety of the bridge, as the safety of the bridge largely depends on the stability of the tie rods. Tie rod anchor blocks without multi-directional stress monitoring functions leave workers without necessary information support during construction, increasing construction risks and safety hazards.
