Description
Technical field
The present invention relates to bridge foundation settlement monitoring early warning field, 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, bridge after building up, due to by weather, burn into oxygen
Change or the factor such as aging, and long-term easy to tamper with the presence of static load and mobile load, correspondingly its strength and stiffness meeting
Reduced with the increase of time.This can not only influence the safety of driving, and can shorten the service life of bridge.To ensure bridge
Safety it is unimpeded with communications and transportation, strengthen particularly important to the maintenance management of bridge work.
Particularly highway bridge in mountainous area, when the detection of foundation scouring situation is not clear, it is impossible to Dangerous Bridge is differentiated in time and
During in normal operation state, it will cause the generation of the particularly serious security incident such as bridge collapse.If can be to the base of bridge
The plinth situation of washing away carries out real-time monitoring, then can in time start emergency mechanism in the state of emergency, bridge is closed, limit for tonnage
Deng measure, it is to avoid the generation of accident.Even if in non-emergent state, it is also possible to by the data of Real-time Feedback, in time to bridge
Beam basis safeguarded, bridge is in normal working condition, reaches the purpose prevented accident.
Monitoring system is applied into highway bridge foundation scouring still in the starting stage both at home and abroad, mainly there are following several prisons
Survey mode：
1st, camera monitoring instrument operational method under Combined water.The advantage of camera monitoring instrument operation is monitoring velocity under Combined water
Hurry up, low cost, and monitoring personnel operation is safer, have the disadvantage it is higher to the environmental requirement monitored, that is, require water-quality ratio compared with
Clearly, surface of base adheres to without microorganisms such as pasture and water and basis partial depth in water is no more than 5 meters.
2nd, diving monitoring resultses method：During monitoring, made by the underwater camera equipment dive of diver's hand held tape lighting apparatus
Industry.Dive under water monitoring advantage be it is relatively low to the water quality requirement near basis no matter clear water, mixed water, in monitored area not
Dead angle is stayed, and while monitoring, some defects can in time be repaired.Have the disadvantage that monitoring velocity is slow, it is costly to monitor
And diver's personal safety threatens larger, when particularly having shipwreck under deep water, tachydromile and bridge, diver
Easily there is security incident.
3rd, underwater robot monitoring resultses method.The advantage of underwater robot monitoring resultses is can deep water monitoring；Shortcoming
It is monitoring cost high, additionally, the propeller power of underwater robot is also not enough at present, the water resistant energy of general submarine inspection operation type
Power is 2~4 sections, is appropriate only for the Basic monitoring of the relatively low Oversea bridge of flow velocity and pile reservoir area, the bridge larger for flow velocity
Basis can not still complete monitoring task.
Above monitoring mode can not carry out being monitored incessantly in real time, and technical costs is high.Current practical technology
Ultrasonic technology is mainly used to realize, as above Nereid 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.One is the akhet of mountain stream
Section property is strong, and water quality is muddy, is mingled with many mudstones and drift, and ultrasonic technology can not apply to bridge foundation washout.Two are
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 very big destruction, and ultrasonic probe is often to be placed in water（It is with water
Transmitting medium）, so monitoring device is easily destroyed.Therefore supervised currently with the bridge foundation washout based on ultrasonic technology
Examining system is only used for hydrostatic bridge, is not suitable for the monitoring of Bridges in Mountainous Areas.
