Description
Technical field
The present invention relates to the monitoring of bridge beam slab degree of disturbing, more particularly to the dress monitored in real time based on bridge defect plate-girder degree of disturbing
Put.
Background technology
It is well known that nonprestressed reinforcement concrete hollow slab girder is used in highway, foot bridge more, it is non-prestressed hollow
Although plate-girder can with joint working, situations such as overloaded vehicle, big traffic flow, ponding under the influence of, crack progressing is more, compared with
It hurry up, the failure of hinge seam, bridge floor are repeatedly damaged, cause single-beam stress, beam slab degree of disturbing is larger or transfinites, or even causes beam slab to be broken.
Traditionally, the assessment to bridge girder (is such as used by manually visually inspecting or being measured by means of portable instrument
Dial gauge is fixed on span centre floor stand or adjacent beam slab, and degree of disturbing is poor between measurement beam slab maximum degree of disturbing or beam slab).Artificial bridge
Inspection is divided into running check, inspected periodically and special examined.But artificial bridge inspection method has very big in actual applications
Limitation.The weak point of traditional detection mode is mainly manifested in：
1) a large amount of manpower and materials are needed, and there are many inspection blind spots；
2) subjectivity is strong, it is difficult to quantify：By the development of over half a century, although the analysis technique of design and construction of bridge
It has been be gradually improved that, but to some response phenomenons, the evolution especially damaged, still in experience accumulation, therefore quantification
Description be critically important；
3) globality is lacked：Hand inspection can only provide instant, local detection and diagnosis using solid memder as object
Information, and real-time monitoring information can not be provided；
4) influence normal traffic operation：Traditional artificial detection needs to suspend traffic or enclosure portion track is so as to influence
The traveling of vehicle on bridge；
5) cycle is long, poor in timeliness, and instant messages can not be provided to policymaker in accident.
6) when having the higher complicated environmental condition in river, headroom under bridge, detect particularly difficult.
Under background above, the conventional periodic detection system of existing highway bridge and development of Mobile Internet technology are used for reference, exploitation is based on bridge
The device that beam disease plate-girder degree of disturbing is monitored in real time, is monitored in real time for beam slab degree of disturbing, and is the final of the present utility model realization
Purpose.

Fig. 2, Fig. 3 are based on bridge defect plate-girder degree of disturbing real-time monitoring device system architecture schematic diagram.
Embodiment
Specific implementation method of the present utility model is further described with reference to embodiment.The embodiment is used for more
The technical solution of the utility model is clearly demonstrated, and protection domain of the present utility model can not be limited with this.
Referring to Fig. 1-Fig. 3, the present embodiment includes the device monitored in real time based on bridge defect plate-girder degree of disturbing, and the present embodiment is adopted
Cap is installed on by fixed support with laser sensor, is connected by cable with control cabinet and solar energy electroplax, in control cabinet
Put battery and 3G module, the device is used for bridge defect beam slab and carries out degree of disturbing real-time monitored, can in the case where not influenceing traffic current,
The quick disease beam slab that obtains disturbs degrees of data, and warning grade is set simultaneously according to the classification scale of bridge superstructure component deliberated index
Alarm, while can be analyzed according to Monitoring Data the change of disease beam slab degree of disturbing, it is ensured that bridge uses safety.
To realize said structure application, implemented according to the following steps：
The first step：Screen disease plate-girder
The non-prestressed plate-girder of disease is screened by inspection：Select girder cracking to develop more, there is crack infiltration, analysis in vain
Phenomenon；Bridge floor is repeatedly damaged, hinge seam failure, veneer degree of disturbing can be observed larger.
Second step：Monitoring device is installed
Designed according to sensor shape, make sensor mounting box, cable retainer ring and base.For concrete structure then
Mainly installed, ensured using cable support system (threading hole, cable trough support, retainer ring etc.) using expansion bolt surface
