Accompanying drawing explanation
Fig. 1 is the schematic diagram of one embodiment of the invention.
Fig. 2 is the schematic diagram of another embodiment of the present invention.
Embodiment
In order to be illustrated more clearly in technical scheme of the present invention, below use embodiment is introduced simply to the present invention, apparently, in the following describes is only one embodiment of the present of invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other technical scheme can also be obtained according to these embodiments, also belong to open scope of the present invention.
Embodiment one
See Fig. 1, road and bridge xoncrete structure real-time monitoring device of the present invention, comprises the container 1 being arranged at xoncrete structure 6 inside, and container 1 inside has gas.One end of pipe 5 is connected with container 1, and other end horizontal direction stretches out xoncrete structure inside.After the other end of pipe stretches out xoncrete structure inside, form the part body 51 extended straight up, the part 51 body rear end extended straight up, there is the part body 52 that horizontal direction extends, part body 52 rear end extended in the horizontal direction, has the part body 53 extended straight down.By such setting, the openend of pipe 5 is arranged down, avoid rainwater to enter the interior impact for liquid column of pipe.Preferably, waterproof ventilative material can be used to seal further at the opening part of pipe 5.
In the middle of the body 51 of pipe 5, liquid column 2 being set, body 51 being also provided with scale lower limit and the scale upper limit, for representing the early warning value of container deformation amount.In order to avoid variation of ambient temperature, the gas in container caused expands with heat and contract with cold for the impact of monitoring result.Can use different marks that multiple scale upper limit and scale lower limit are set at body 51, as described in Figure 1, can arrange as being greater than first scale lower limit 42 and the first scale upper limit 32 of 30 degree of environment under hot environment, low temperature environment is as second scale lower limit 41 and the second scale upper limit 31 being less than 0 degree.At high temperature expand because gas reduces at low temperatures, therefore the first scale lower limit 42 higher than described second scale lower limit 41, the first scale upper limit 32 higher than the second scale upper limit 31.
The monitoring method of above-mentioned road and bridge xoncrete structure real-time monitoring device, the container 1 comprising the steps: inside to have gas is positioned over xoncrete structure 6 inside; Be connected with container 1 one end of pipe 5, it is inner that the other end stretches out described xoncrete structure; Inject liquid from the opening of pipe, form liquid column 2; Change container 1 volume change caused according to xoncrete structure, thus cause the lifting of liquid column 2, the change for xoncrete structure judges.
Embodiment two
See Fig. 2, the road and bridge xoncrete structure real-time monitoring device of embodiments of the invention two, comprises the first container 100, and it is inner that it is arranged at xoncrete structure 101, inner insufflation gas.Second container 200, it has the shape identical with the first container 100, and inside is filled with the gas identical with the first container 100.It is outside that second container 200 is arranged at xoncrete structure 101, uses the 3rd container 300 of inner hollow to hold second container 200, avoid second container 200 to be subject to the impact of environment.
Pipe 400 is " several " font, has two bottom pipe parts 401 and 402 of horizontal direction, the pipe section 403 and 404 of vertical direction, the top pipe portion 405 of horizontal direction.One end of pipe 400 is connected with the first container 100, and the other end is connected with second container 200.Inject liquid in pipe 400 inside, be filled with the gas lower than the first container 100 internal gas pressure in second container 200 inside, form the liquid column 500 in the middle of the vertical pipeline part 403 being positioned at pipe 400.The tube wall of vertical pipeline part 403 is provided with the scale upper limit 602 and scale lower limit 601.If liquid column is beyond the scale upper limit or lower range, then represent that container 100 deflection is beyond early warning value, namely the amount of deflection of inside concrete or distortion are beyond early warning value.
In the arranging of the above-mentioned road and bridge xoncrete structure real-time monitoring device of embodiment two, by employing the second container identical with the first container, the gas variable effect monitoring quality avoiding ambient temperature effect to cause.In high temperature environments, first container and the gas in second container cause owing to being heated increasing together with pressure, during low temperature environment, first container causes reducing together with pressure because temperature reduces with the gas in second container, thus liquid column is remained unchanged under the change of environment temperature, thus avoid the impact of environment temperature.Therefore, in embodiment two, only need to arrange a scale upper limit and a scale lower limit.
The monitoring method of above-mentioned road and bridge xoncrete structure real-time monitoring device, comprises the steps: the first container to be arranged at xoncrete structure inside, inner insufflation gas; Second container with the first container same shape is arranged at xoncrete structure outside; Use pipe one end to be connected with described first container, the other end is connected with described second container, and described pipe is " several " font, and centre is provided with liquid column, and described pipe is provided with the scale upper limit and scale lower limit; According to the change of described liquid column position, judge the overall variation situation of xoncrete structure.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
