Device for measuring relative deformation

Abstract

The invention provides a device for measuring relative deformation. The device comprises a rotary measuring rod, a fixed measuring rod, a data processing device, a first probe, a second probe, a third probe, a fourth probe, a fixed plate, a fixed bracket and the like, wherein an included angle alpha between a subgrade plane and the horizontal ground and an included angle beta between an abutment plane and the horizontal ground are measured respectively through the four probes, so that included angle definition phi between an abutment and a subgrade is calculated. The settlement of a bridge deck and the subgrade is obtained through the change of a numerical value of the included angle definition phi and relative movement of the bridge deck and the subgrade is judged. According to the device for measuring the relative deformation, provided by the invention, the settlement of the bridge deck and the subgrade can be monitored in real time through the rotary measuring rod, the fixed measuring rod, the data processing device, the first probe, the second probe, the third probe, the fourth probe, the fixed plate, the fixed bracket and the like; the device provided by the invention has the advantages of high precision, good reliability and the like.

Description

[0001] This application claims the priority of the following Chinese patent applications: (1) Chinese invention patent application titled "A Device for Measuring Relative Deformation" with application number 201710724238.2 filed on August 22, 2017. technical field [0002] The invention relates to the field of engineering measurement and control, in particular to the precise measurement of the settlement or buoyancy of an engineering foundation filling structure, in particular to a device for measuring relative deformation. Background technique [0003] With the development of social economy, my country has built a large number of basic facilities such as hydropower dams, high-rise buildings, highways, bridges, embankments, oil and gas pipelines, and oil storage tanks. Before construction, a large number of precise measurements of the foundation fill structure of the building are required to evaluate the settlement or buoyancy risk of the infrastructure. [0004] At present,...
