Description
Technical field
The present invention relates to bridge safety supervision field, specifically a kind of small bridge safety remote monitoring device and
Its method.
Background technology
Small bridge has substantial amounts of composite assembly structural bridge, and between its beam, relative deformation is the control ginseng of its safety monitoring
Number, before many due to beam, comprehensive monitoring there is no good method, daily inspection can only be relied on and make regular check on.
Inspection human cost is high, and impossible every day is to operation on bridge, and makes regular check on the most annually, it is impossible to
Play monitoring effect.Though bridge is made regular check on can accurately identify bridge security performance, but periodic detection is periodic, for bridge
There is time blind area in the monitoring of safety beam, cannot feed back in time for the burst accident during detection week.
Summary of the invention
The present invention is for overcoming the deficiencies in the prior art, in loading characteristic based on small bridge, Structural Feature Design one
Little bridge safty remote monitoring device.
For achieving the above object, a kind of small bridge safety remote monitoring device of design, including bridge, Acquisition Instrument, steel
Silk, sensor, it is characterized in that: described bridge is made up of the beam slab that some left and right are placed side by side, under described two pieces of adjacent beam slabs
Side is provided with a fixture, is fixed with steel wire and steel wire parallel with the bottom of beam slab in described fixture；The right side of described bridge is provided with
Acquisition Instrument, is positioned on the right side of the bridge below Acquisition Instrument and is provided with sensor.
Described steel wire is connected with beam slab by fixture.
Described Acquisition Instrument connects sensor by a holding wire.
A kind of small bridge safety remote monitoring method, is characterized in that being to comprise the steps:
(1) step 1: determine scratching of bridge to be measured according to the version of bridge, beam slab type, the data such as quantity of every bridge plate
Degree warning value X；
(2) step 2: quantity and beam slab width according to every bridge plate prepare an a length of L0Steel wire, subsequently bridge survey
Examination cross section is drawn and is set this steel wire, by fixation with steel wire and makes steel wire be connected with every piece of beam slab by fixture；
(3) step 3: install displacement monitoring sensor outside bridge, monitor the change of steel wire length in real time；
(4) step 4: if recording steel wire length by initial L0Become L1, then L1With L0Between poor Δ l be then tested bridge
Amount of deflection changing value；
(5) step 5: according to the amount of deflection changing value collected, calculates tested bridge whether safety.
The present invention compared with the existing technology, simple in construction, easy to use；Having good in anti-interference performance, data are reliable, and 24 is little
Time the feature such as uninterrupted remotely monitoring, low cost in real time.
Accompanying drawing explanation
Fig. 1 is the structural representation that this use is novel.
Seeing Fig. 1, wherein, 1 is beam slab, and 2 is steel wire, and 3 is fixture, and 4 is Acquisition Instrument, and 5 is holding wire, and 6 is sensor, 7
It it is bridge.
Detailed description of the invention
Below according to accompanying drawing, the present invention is described further.
As it is shown in figure 1, described bridge 7 is made up of the beam slab 1 that some left and right are placed side by side, described two pieces of adjacent beam slabs 1
Lower section is provided with a fixture 3, is fixed with steel wire 2 and steel wire 2 parallel with the bottom of beam slab 1 in described fixture 3；Described bridge 7
Right side is provided with Acquisition Instrument 4, is positioned on the right side of the bridge 7 below Acquisition Instrument 4 and is provided with sensor 6.
Described steel wire 2 is connected with beam slab 1 by fixture 3.
Described Acquisition Instrument 4 connects sensor 6 by a holding wire 5.
A kind of small bridge safety remote monitoring method, is characterized in that being to comprise the steps:
(1) step 1: determine scratching of bridge to be measured according to the version of bridge, beam slab type, the data such as quantity of every bridge plate
Degree warning value X；
(2) step 2: quantity and beam slab width according to every bridge plate prepare an a length of L0Steel wire, subsequently bridge survey
Examination cross section is drawn and is set this steel wire, by fixation with steel wire and makes steel wire be connected with every piece of beam slab by fixture；
(3) step 3: install displacement monitoring sensor outside bridge, monitor the change of steel wire length in real time；
(4) step 4: if recording steel wire length by initial L0Become L1, then L1With L0Between poor Δ l be then tested bridge
Amount of deflection changing value；
(5) step 5: according to the amount of deflection changing value collected, calculates tested bridge whether safety.
When the present invention uses, the testing section at beam slab 1 draws the steel wire 1 setting a customization so that steel wire 1 is by being fixed on
Fixture 3 below adjacent beam slab 1 is connected with every piece of beam slab 1, installs sensor 6, described sensor 6 in the outside of bridge 7 simultaneously
For displacement detecting sensor, then by holding wire 5, sensor 6 and Acquisition Instrument 4 are connected, thus monitoring steel wire 1 length in real time
Change, utilizes the amount of deflection change of changing value this bridge of inverse of steel wire 1 length, and finally pushes away according to deflection monitoring gained deflection value
Calculate the safe condition of this bridge.
Embodiment one:
In one hollow slab girder simply supported girder bridge a certain across, span length 6m, superstructure is made up of 6 pieces of hollow slab girders, hollow slab girder
Beam slab width 0.99m, high 0.52m, according to the version of monitored spanning and the type of plate-girder and specification, by Criterion restriction and should
Bridge disease checks Relative Deflection limit value between corrected Calculation plate-girder.If this bridge Relative Deflection limit value is 20mm, when sensor test
When numerical value is more than 20mm, then the length of steel wire change has been over the limit value of Relative Deflection change between plate-girder, and now bridge holds
Loading capability situation is poor, need to carry out reinforcing maintenance.
