Inhaul cable corrosion monitoring sensor, monitoring equipment and monitoring method

Abstract

The invention provides an inhaul cable corrosion monitoring sensor, monitoring equipment and a monitoring method. The inhaul cable corrosion monitoring sensor comprises two bases, a supporting column,a probe, a pressure ring, an anchor head, and two transmission lines; the two bases are opposite and are arranged at an interval, and the two are connected through the supporting column; the probe penetrates through the two bases at the same time, and two ends of the probe are positioned outside the two bases; one end of the probe is provided with a pier head, and the other end of the probe is fixed through the anchor head; the pressure ring is installed between the anchor head and the bases and used for measuring prestress exerted on the probe; the two transmission lines are installed at thetwo ends of the probe respectively; one end of each transmission line is connected with the probe, and the other end of each transmission line is used for being connected with an external collector.The inhaul cable corrosion monitoring equipment comprises the inhaul cable corrosion monitoring sensor, an acquisition instrument, a prestress tensioning device and a terminal device. The monitoring method is carried out by adopting the monitoring equipment, and the corrosion condition of the bridge inhaul cable under stress can be monitored in real time through the monitoring method.

Description

technical field [0001] The invention relates to the technical field of cable bridge monitoring, in particular to a cable corrosion monitoring sensor, monitoring equipment and a monitoring method. Background technique [0002] Cable-stayed bridges are widely used in my country. The cables mainly include suspenders of arch bridges, stay cables of cable-stayed bridges, cables and suspenders of suspension bridges, etc. The cables are usually made of metal. Although the cables are usually treated with anti-corrosion treatment in the construction of cable-type bridges, the corrosion of the cables is inevitable because the bridge structure is often in a very complex natural environment. At the same time, since the cables are usually in a state of stress, this also aggravates the corrosion rate of the cables. Bridge accidents caused by cable corrosion are not uncommon, such as the large vortex-induced vibration of the Humen Bridge. One of the reasons is that the cable has to be rep...
