The invention discloses an attached type bridge pile foundation scouring accumulated sludge real-time monitoring system which comprises an ultra-weak grating array self-heating temperature optical cable, a plurality of fixing clamps, a channel steel drill bit, a lead and wireless demodulation equipment. The multiple fixing clamps are arranged at intervals in the longitudinal direction of a bridge pile foundation, and the channel steel drill bit is fixed to the tail end of the bridge pile foundation and located below a riverbed. The ultra-weak grating array self-heating temperature optical cable is longitudinally fixed to the bridge pile foundation, and the wireless demodulation equipment is connected with the ultra-weak grating array self-heating temperature optical cable through a lead. And the wireless demodulation equipment is used for data acquisition, data processing, data storage and data wireless transmission of the ultra-weak grating array self-heating temperature optical cable. The invention further discloses a real-time monitoring method for the scour accumulated sludge of the attached bridge pile foundation. The system has the characteristics of simple structure, high engineering field practicability, high monitoring precision, low operation and maintenance cost, unmanned real-time testing, wireless data transmission and the like.
Description
technical field [0001] The invention relates to the technical field of bridge structure health monitoring. More specifically, the present invention relates to an attached bridge pile foundation scour accumulation real-time monitoring system and method. Background technique [0002] my country is a big country of bridges, and bridges are an important part of transportation. Among them, bridge pile foundations are mostly located underwater, and are subject to erosion and erosion by water flow all year round, and the surrounding riverbed surface is also affected by local erosion. Local scour of bridge pile foundations may cause sudden catastrophic consequences and cause adverse social impacts. [0003] In recent years, the health monitoring of bridges has developed rapidly, which is related to smooth roads and driving safety. Among them, ground-penetrating radar scour monitoring technology and echo sounding scour monitoring technology are widely used in monitoring bridge pile...
