Description

Technical Field

[0001] The utility model relates to the technical field of bridge preloading construction, in particular to a settlement measurement device and a measurement system for support preloading. Background Art

[0002] Prestressing refers to the application of a predetermined load to a concrete structure to alter its internal force distribution and improve its load-bearing capacity and seismic resistance. In bridge supports, prestressing is based on applying a predetermined pressure to create greater internal stress in the concrete. This increases friction between the piers and the deck, improving the support's stability and durability. During the prestressing process, deformation of the support is measured, providing empirical data for bridge construction.

[0003] At present, the deformation of bridge supports is generally observed by measuring the settlement of the bridge supports during the pre-stressing process. During the measurement process, a load is generally added to the template after the template on the top of the bridge support is installed, and observation points are set at fixed positions on the template. A total station is used to observe each observation point and measure the elevation of each observation point. However, the measurement process requires the operator to manually support the fixed observation device and repeat the operation at each observation point. The operation steps are cumbersome and the measurement efficiency is low. Utility Model Content
