Device and method for detecting vertical displacement of bridge

Abstract

The invention provides a device and a method for detecting vertical displacement of a bridge. The method comprises the following steps: arranging static force level gauges in a plurality of test groups at corresponding monitoring points, and arranging one static force level gauge in a reference point group at a reference point; connecting the other static force level gauge in the reference point group with the static force level gauge at the first monitoring point; using each static force level gauge to acquire data and transmitting the data to a control center through a wireless communication module; and using the control center to calculate the vertical displacement of the to-be-measured bridge according to the data transmitted by each static force level gauge. According to the invention, the detection of the vertical displacement of the to-be-measured bridge can be completed.

Description

technical field [0001] The present application relates to the technical field of bridge detection, in particular to a device and method for detecting vertical displacement of a bridge. Background technique [0002] In the current prior art, there are many kinds of displacement test sensors, for example, laser range finder, inclination sensor, layered settlement meter, displacement meter, level gauge, crack gauge, GPS, static level gauge and so on. The vertical displacement of the bridge is usually detected by a level gauge. However, the application environment of the level gauge has certain limitations. For example, in a dark or foggy environment, the optical lens cannot observe the scale scale; The vertical pole cannot test the deflection of the vault; no suitable reference point can be found; the elevation difference between the reference point and the measuring point is very large, and it is necessary to transfer to the measuring station several times to meet the measurem...

Problems solved by technology

The vertical displacement of the bridge is usually detected by a level gauge. However, the application environment of the level gauge has certain limitations. For example, in a dark or foggy environment, the optical lens cannot observe the scale scale; The vertical pole cannot test the deflection of the vault; no suitable reference point can be found; the elevation difference between the reference point and the measuring point is very large, and it is necessary to transfer several stations to meet the measurement requirements, which invisibly reduces the test accuracy

Secondly, when using a level to read data, it generally takes several minutes or even more than ten minutes, which is time-consuming; moreover, manual reading is also easy to cause errors or even errors
