Bridge health monitoring support and monitoring system

Abstract

The invention discloses a bridge health monitoring support and a monitoring system, which are used to solve the problems that manual detection of a bridge support located in a hidden and severe engineering environment is inconvenient, all-weather monitoring cannot be achieved by manual periodic detection, meanwhile, the number of bridge supports is large, the manual detection period is long, and the safety problem of the bridge is difficult to judge. A health monitoring support group is composed of a plurality of health monitoring supports. The health monitoring support is composed of a functional part, an optical fiber force measuring sensor, a displacement sensor and an inclination angle sensor. The functional part is composed of a lower support plate, a spherical crown lining plate, anupper support plate, a plane sliding plate, a sealing ring, a plane sliding plate, a middle plate, a wedge-shaped ring, an upper support plate, a middle plate, a wedge-shaped ring and a lower supportplate. The displacement sensor and the inclination angle sensor are in transmission and connection with a monitoring and collecting center through optical fibers.

Description

technical field [0001] The invention belongs to the field of girder bridge bearings, relates to beam bridge bearing technology, and specifically relates to a bridge health monitoring bearing and a monitoring system. Background technique [0002] With the rapid development of bridge engineering technology and large-scale building structures, people pay more attention to the safety and durability of bridges and large-scale buildings, and health monitoring systems emerge as the times require. The health monitoring system mainly obtains various data reflecting the behavior of the structure by measuring various response sensing devices, and provides scientific reference for analyzing the health status of the structure and evaluating the reliability of the structure. At present, regular manual inspection is to obtain bridge support It is a common means of health status, but the bridge bearings are in a hidden and harsh engineering environment, and manual inspection is inconvenient...

Problems solved by technology

[0003] The purpose of the present invention is to provide a bridge health monitoring support and monitoring system, which is used to solve the problem that the bridge support is in a concealed and harsh engineering environment, and manual detection is inconvenient. At the same time, manual regular detection cannot achieve all-weather monitoring. There are a large number of bridges, and the manual inspection cycle is long, so it is difficult to judge the safety of the bridge
