Bridge strain monitoring and sensing device and monitoring method thereof

Abstract

The invention relates to the technical field of bridge engineering construction and discloses a bridge strain monitoring and sensing device and a monitoring method thereof. The bridge strain monitoring and sensing device comprises a bridge body and a bridge strain monitoring and sensing system, wherein a supporting column is fixedly mounted in the middle of the bridge body; the back surface of thesupporting column is movably connected with a supporting plate; locking screws sleeve two sides of the front surface of the supporting column through threads; the other ends of the locking screws penetrate through and extend to the back surface of the supporting column and are sleeved with the outer surface of the supporting plate through threads. According to the bridge strain monitoring and sensing device provided by the invention, the supporting plate is fixed on the back surface of the supporting column through the two locking screws and the supporting plate is convenient to replace; a vibrating wire strain gauge in a sleeve groove is convenient to overhaul; a fixed plate, a supporting rod and a base plate are combined to use and the balance stability of the supporting plate is easy to improve, so that the accuracy of monitored data of the vibrating wire strain gauge is improved and a condition that normal monitoring is influenced, caused by the fact that the vibrating wire straingauge falls off or is damaged by accident, is avoided.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a bridge strain monitoring sensor device and a monitoring method thereof. Background technique [0002] The construction of long-span bridges in my country has made great achievements in recent years, among which bridge construction monitoring has played an important role in technical support. Summarizing engineering experience, it can be found that the widely used construction strain monitoring data based on vibrating wire strain sensors is particularly important. Strain testing techniques in bridge construction monitoring need further research. [0003] At present, most of the sensor technology is used to monitor the corresponding strain of the bridge. The most widely used is to bond the strain gauge at the bottom of the bridge. The bottom of the bridge falls off, and the current monitoring method is too simple, and the transmission efficiency of the sen...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bridge strain monitoring sensing device and its monitoring method, which has the advantages of easy installation of strain gauges, high data transmission efficiency, and good monitoring effect, and solves the problem of bonding strain at the bottom of the bridge. Timing, because the bonding is not firm enough, the strain gauge is prone to damage or falls off from the bottom of the bridge under the action of water or other factors, the monitoring method is too simple, and the transmission efficiency of sensing data is too low
