Description
Technical field
The present invention relates to bridge foundation settlement monitoring early warning fields, and in particular to a kind of round-the-clock long-range bridge foundation washout
Monitoring and warning system.
Background technology
Bridge occupies consequence in highway transportation, and bridge is after building up, due to by weather, burn into oxygen
The factors such as change or aging, and easy to tamper under the action of static load and mobile load for a long time, correspondingly its strength and stiffness meeting
Increase at any time and reduce.This can not only influence the safety of driving, and can make the reduced service life of bridge.To ensure bridge
Safety and communications and transportation it is unimpeded, reinforce particularly important to the maintenance management of bridge work.
Especially highway bridge in mountainous area, when foundation scouring situation detection it is unknown when, Dangerous Bridge cannot be differentiated in time and
When in normal operation state, it will lead to the generation of the particularly serious safety accident such as bridge collapse.If can be to the base of bridge
Plinth washes away situation and is monitored in real time, then can start emergency mechanism in time in the state of emergency, is closed to bridge, limit for tonnage
Equal measures, avoid the generation of accident.Even if, can also be by the data of Real-time Feedback, in time to bridge in non-emergent state
Beam basis is safeguarded, so that bridge is in normal working condition, is achieved the purpose that prevent accident.
Monitoring system is applied into highway bridge foundation scouring both at home and abroad and is still in the starting stage, is mainly the following prison
Survey mode：
1, camera monitoring instrument operational method under Combined water.The advantages of camera monitoring instrument operation, is to monitor under Combined water
Speed is fast, at low cost, and monitoring personnel's operation is safer, the disadvantage is that the environmental requirement to monitoring is relatively high, that is, requires water quality
Compare clear, surface of base without the attachment of the microorganisms such as water plant and basic partial depth in water is no more than 5 meters.
2, diving monitoring results method：When monitoring, made by the underwater camera equipment dive of diver's hand held tape lighting apparatus
Industry.The advantages of diving monitoring be it is relatively low to the water quality requirement near basis no matter clear water, mixed water, in monitoring region not
Dead angle is stayed, and while monitoring, some defects can be repaired in time.The disadvantage is that monitoring velocity is slow, monitoring is costly
And diver's personal safety threat is larger, and when especially having shipwreck under deep water, tachydromile and bridge, diver
It is susceptible to safety accident.
3, underwater robot monitoring results method.The advantages of underwater robot monitoring results is can deep water monitoring；Disadvantage
It is monitoring cost height, in addition, the propeller power of underwater robot is also insufficient at present, the water resistant energy of general submarine inspection operation type
Power is 2~4 sections, the Basic monitoring of the relatively low Oversea bridge of flow velocity and pile reservoir area is appropriate only for, for the bridge that flow velocity is larger
Basis cannot still complete monitoring task.
The above monitoring mode cannot carry out being monitored incessantly in real time, and technical costs is high.Practical technology at present
Mainly ultrasonic technology is utilized to realize, Nereid as above leads the bridge scouring monitoring system of Scientific Instruments Corporation exploitation.But this is
System is primarily adapted for use in the application on hydrostatic bridge.Bridges in Mountainous Areas foundation scouring has its particularity.First, the akhet of mountain stream
Section property is strong, and water quality is muddy, is mingled with many mudstones and drift, ultrasonic technology cannot apply to bridge foundation washout.Second is that
The flood of mountain stream breaks with tremendous force, and flow velocity is fast, and has the drifts such as mudstone,
The monitoring device being opposite in water has prodigious destruction, and ultrasonic probe is often to be placed in water（With
Water is transmitting medium）, so monitoring device is easily destroyed.Therefore it is rushed currently with the bridge foundation based on ultrasonic technology
Brush monitoring system is only used for hydrostatic bridge, is not suitable for the monitoring of Bridges in Mountainous Areas.
