Background technique
The building-up work of traditional high-speed rail large span concrete continuous beam, because its adaptability and economy rapidly become acrossMost competitive bridge type within the scope of diameter 60-300M, due to domestic bridge structure design and materials theory be not also it is very perfect,In addition the reasons such as volume of transport, the limitation of maintenance management and natural conditions severe in recent years for being increasingly incremented by, causeThe various problems and structural disease of Partial Bridges, are mainly shown as the cracking and middle span deflexion of pontic web, bottom plate and top plateThe problems such as, less serious case influences beam structure durability and beauty, will limit the normal use of bridge when serious or structure is caused to be lostBearing capacity is lost, is become more and more important to the reinforcing and monitoring of old bridge, unsafe bridge, since the continuous beam length of high-speed rail is longer, andAnd most of sections are located at the few countryside of human footmarks, so that daily monitoring becomes difficult, monitoring personnel is not easy in timeIt was found that the section of problem will occur with early warning bridge, monitoring time is delayed, has caused security risk to train.
Summary of the invention
The object of the present invention is to provide a kind of high-speed rail continuous beam monitor system, the system can dynamic gamut monitoringThe health status of suburb high-speed rail continuous beam finds pontic web, bottom plate, the cracking of top plate and middle span deflexion phenomenon and timely in advanceEarly warning facilitates staff to determine that security risk position is repaired, avoids peril, improves the safety of high-speed rail continuous beamAnd stability.
To achieve the goals above, The technical solution adopted by the invention is as follows:
A kind of high-speed rail continuous beam monitoring system, including several regional monitoring stations, each regional monitoring station monitor 200-300Meter Gao Tie continuous beam range is equipped with monitoring device between the two neighboring bridge pier of high-speed rail continuous beam inside each regional monitoring station,The monitoring device includes base cabinet, and two sides and middle position are equipped with connecting rod above the base cabinet,The connecting rod is equipped with sensor mounting box, includes that differential deformation measurement senses inside the sensor mounting boxThe fixed inclinometer of device, boxlike, surface-type strain gauge, magnetoelectric sensor, slit gauge, Temperature Humidity Sensor and anemoclinograph,The differential deformation measurement sensor and the fixed inclinometer of boxlike are respectively placed at bridge pier, beam body and arch ring position, describedSurface-type strain gauge and magnetoelectric sensor be respectively placed at beam body and pier location, the slit gauge be placed in beam body maximumAt slit width, the Temperature Humidity Sensor and anemoclinograph are respectively placed at beam face, beam bottom and span centre position, the connectionSeveral positioning and rolling wheels are additionally provided between rod piece and continuous beam, middle position passes through spring link above the base cabinetIt is connected with driving roller, there is sliding block at the base cabinet both ends by connection limit band connection, and the sliding block is slidably installedOn the slide rail, the sliding rail is separately fixed at continuous beam beam face two sides, and the bridge pier is equipped with power supply box, the power supplyCase is equipped with device of solar generating, and the power supply box is connect by route with base cabinet.
It further, include controller, biosensor information processor, sensor information transmitter inside the base cabinetWith small-sized driving motor, the sensor information receiver, sensor information transmitter and small-sized driving motor pass through lineRoad is connect with controller, and the biosensor information processor is connect by route with sensor mounting box, the small-sized driveDynamic motor is connect by transmission mechanism with driving roller.
Further, include inside the regional monitoring station power supply, GPS module, sensor information receiver, controller andMonitoring, alarming module, the power supply, sensor information receiver, GPS module and alarm module pass through route and controllerConnection.
Further, the sensor information transmitter and sensor information receiver are using wireless signal progress information friendshipIt changes.
Further, the monitoring, alarming module uses 2G or 3G signal.
The working principle of this system is to drive driving roller to drive between two adjacent bridge piers by small-sized driving motorMonitoring device slowly moves, so that sensor mounting box be driven to move, carries out parameters to the every fragment position of high-speed rail continuous beamInspection operation will test information and be believed by the sensor that the sensor information transmitter in base cabinet is transported to regional monitoring stationIt ceases on receiver, sets the safe range thresholding of every sensor detection parameters in the controller of regional monitoring station in advance, whenWhen there is abnormality detection parameter, maintenance monitoring staff's mobile device to is sent warning message by detection alarm moduleOn, remind staff to find the problem and be monitored in time.
Compared with the prior art, beneficial effects of the present invention are as follows:
The continuous beam in certain area is segmented respectively using several monitoring devices in the present invention (adjacent bridge pier itBetween) dynamic monitoring, monitoring range is comprehensive, and monitoring effect is good；Several monitoring devices are monitored by several regional monitoring stationsInformation carries out aggregation process, facilitates staff to determine generation problem continuous beam region, facilitates position monitor to repair, find in advancePontic web, bottom plate, the cracking of top plate and middle span deflexion phenomenon and timely early warning avoid peril, improve high-speed rail and connectThe safety and stability of continuous beam.
