Description

A kind of mechanical bridge foundation washout monitoring device

Technical field

The utility model is related to bridge foundation settlement monitoring early warning field, and in particular to a kind of mechanical bridge foundation washout Monitoring device.

Background technology

Bridge occupies consequence in highway transportation, and bridge is after building up, due to by weather, burn into oxygen The factor such as change or 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 and communications and transportation it is unimpeded, 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 Plinth washes away situation and monitored in real time, then can start emergency mechanism in time in the state of emergency, bridge is closed, limit for tonnage Deng measure, it is to avoid the generation of accident., can also be by the data of Real-time Feedback, in time to bridge when non-emergent state Beam basis is safeguarded, bridge is in normal working condition, is reached the purpose prevented accident.

Monitoring system is applied into highway bridge foundation scouring both at home and abroad and is still in the starting stage, 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 to monitor under Combined water Speed is fast, cost is low, and monitoring personnel's operation is safer, has the disadvantage that the environmental requirement to monitoring is higher, that is, requires water quality Comparing clear, surface of base, the partial depth in water is no more than 5 meters without the attachment of the microorganisms such as pasture and water and basis.

2nd, diving monitoring resultses method：During monitoring, made by the underwater camera equipment dive of diver's hand held tape lighting apparatus Industry.The advantage of diving monitoring 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 that monitoring cost is high, in addition, 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, 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 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, 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 a 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（With Water is transmitting medium）, so monitoring device is easily destroyed.Therefore 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.
