Old bridge body external beam reinforcement under-anchor prestress full-life intelligent monitoring device and method

Abstract

The invention provides an old bridge body external beam reinforcement under-anchor prestress full-life intelligent monitoring device and method. The device comprises a box body, an anchor cable dynamometer, an intelligent processing terminal and a solar panel, wherein an under-anchor force collector, a wireless transmitter and a storage battery are arranged in the box body, the solar panel is electrically connected with the storage battery to achieve solar power supply, energy conservation and environmental protection, specifically, the under-anchor force collector obtains the under-anchor force monitored by the anchor cable dynamometer and then transmits the under-anchor force to the intelligent processing terminal through a wireless transmitter, and the intelligent processing terminal analyzes the under-anchor pre-stress, so that intelligent monitoring of the under-anchor pre-stress of the external beam reinforcement of the old bridge body from reinforcement construction to the whole life cycle of the service period is achieved, the change condition of the prestress under the in-vitro anchor beam at any stage can be mastered in real time, and more scientific reference data is provided for a bridge management and maintenance decision. According to the invention, the device is powered by solar energy, mechanical equipment is not needed in regular inspection after old bridge reinforcement service, monitoring data can be analyzed autonomously, and economical efficiency and intelligence are achieved.

Description

technical field [0001] The application relates to the technical field of under-anchor prestress intelligent monitoring technology for external beam reinforcement of old highway bridges, in particular to an intelligent monitoring device and method for the whole life of the old bridge external beam reinforcement under anchor prestress. Background technique [0002] With the continuous development of highway bridge construction in our country, prestressed concrete bridges are widely used. More and more old bridges are strengthened with external beam prestressing, and the prestressing under anchorage will be lost to varying degrees with the service time. Therefore, it is particularly important to carry out real-time intelligent monitoring of the whole life cycle of the anchorage prestress of the old bridge external beam, which can provide more scientific reference data for bridge management and maintenance decisions. [0003] Due to the obvious problem of emphasizing constructi...

AI Technical Summary

Problems solved by technology

The under-anchor prestress of the old bridge external beam reinforcement has different degrees of loss during the service period, and the existing monitoring methods only focus on the artificial collection and monitoring of the anchor prestress in the new bridge body. The whole life cycle of stress lacks accurate and effective remote monitoring and evaluation
