Telescopic probe-type monitoring system for pier bed elevation

Abstract

The invention relates to a telescopic probe-type monitoring system for pier bed elevation. The monitoring system comprises a measurement module and a control module. The measurement module measures an elevation of a bed under water and comprises a housing, multilayer pipe body, a promotion unit, a photography unit and a sensing unit. The promotion unit comprises multiple scales and promotes the multilayer pipe body to elongate to the bed; the photography unit photographs the promotion unit to generate image. The control module controls the promotion module to promote the elongation of the multilayer pipe body, so that when the sensing unit at the bottom of the multilayer pipe body touches the bed under water, the sensing unit sends a sensing signal to the control module, and the control module stops promoting the multilayer pipe body and controls the photography unit to photograph the promotion unit; the control module acquires a pier bed elevation and sends the pier bed elevation to a remote supervision unit, according to image or actuate state of the measurement module, so as to monitor bed elevation on a real-time basis.

Description

technical field [0001] The invention relates to a monitoring system for the elevation of the pier bottom bed, in particular to a telescopic probe type monitoring system which can monitor the elevation of the pier bottom bed in real time. Background technique [0002] In recent years, there have been frequent wind and flood disasters in countries all over the world. Whenever disasters come, rivers and streams often swell, causing serious erosion of bridge pier foundations, leaving the foundation piles of bridge piers exposed, which will lead to insufficient lateral bearing capacity of the bridge. As a result, tilting or breaking occurs. If the flood is too large, it will directly break the bridge piers, and then cause the bridge to suddenly fall directly into the water, endangering traffic safety. The above situation not only leads to the interruption of traffic communication, but also often causes the loss of people's lives, public property and local construction in a short...

Problems solved by technology

The disadvantage is that if the water surface is too high from the sand surface, the required measuring rod must be longer, and if the water level soars, the device is easily damaged by external forces such as floods or large rocks

[0014] It can be known from the above-mentioned monitoring methods commonly used today that they all have certain limitations and inconveniences in use. Therefore, how to monitor the scour state of the bed of the bridge pier in other better ways to prolong the service life of the bridge is still an issue today. an important topic of
