Description

TECHNICAL FIELD [0001] The present invention relates to a steel plate culvert monitoring system using a wire sensor and a method of monitoring the steel plate culvert culvert using the wire sensor.

The present invention relates to a corrugated steel plate culvert monitoring system using a wire sensor and a method therefor.

Concrete structures to be installed in civil engineering and architectural fields require a lot of work such as formwork, reinforcement and concrete casting, and the construction period is prolonged. Therefore, relatively small civil engineering and building structures are constructed by the construction method using corrugated steel sheet.

Generally, a corrugated steel sheet is formed by forming a corrugated shape on a steel sheet, and the load and the reaction force are uniformly distributed throughout the steel sheet due to the corrugation, so that the load bearing capacity is large. Structures made of corrugated steel plates are more economical than concrete structures, and thus are used as underground passageways traversing highways and railways, culvert / drainage culverts, and tunnel structures.

When the culvert is constructed on the road, the culvert plays a role of conveying the heavy buried soil and the vehicle load of the road structure to the ground, and makes the vehicle and the person move in the lateral direction of the road blocked by the road. As a result, the culvert is an underground structure, and it is required that the ground subsidence should not be induced while fully supporting the uniform distribution load by embankment load and traffic load.

1 is a front view showing an example of a conventional corrugated steel plate culvert. As shown in the figure, the conventional corrugated steel plate culvert comprises two concrete supports 100 positioned in parallel to each other and an arch-shaped corrugated steel plate 200 installed on the two concrete supports 100 .

The construction of such a conventional corrugated steel plate culvert proceeds as follows. First, a concrete form for a concrete pedestal is installed in the lower part of the culvert. After reinforcing the reinforcing bars to the form, the anchors are fixed to the upper part of the reinforcing bars. Concrete is cured and cured to form the concrete pedestal. Then, the base channel is joined to the anchors provided at the upper part of the concrete support, and the corrugated steel plate installed on the excavation surface of the culvert is fastened and fixed to the base channel using bolts and nuts. Then, backfilling is made on the top of the culvert and the construction of the corrugated steel plate culvert is completed.

As shown in FIGS. 2 and 3, the arc-shaped corrugated steel plate 200 is formed by connecting a plurality of unit corrugated steel plates 210 in an arch shape for easy manufacture and transportation, And the unit corrugated steel plates 210 are connected by fixing the fixing bolts 220 and the fixing nuts to the overlapped through holes in the state where the through holes of the unit corrugated steel plates 210 are overlapped with each other .

Such a corrugated steel plate culvert can be formed by the repetitive bending moments caused by the pressure of the ground (300) and the vehicle pressure on the ground, the stress imbalance of the corrugated steel sheet due to the erroneous compaction of the soil during construction, 200 is likely to be deformed. In particular, when the arcuate corrugated steel sheet 200 is composed of a plurality of unit corrugated steel sheets 210, the possibility of deformation of the arcuate corrugated steel sheet 200 is increased. If such deformation is generated continuously and minutely, the corrugated steel sheet culvert may be damaged and safety problems may arise.

An object of the present invention is to provide a corrugated steel plate culvert monitoring system and a method thereof using a wire sensor, which prevents damage due to breakage of a corrugated steel plate culvert by monitoring the corrugated steel plate culvert at all times.

Another object of the present invention is to provide a corrugated steel plate culvert monitoring system and a method thereof using a wire sensor, which facilitates maintenance of a corrugated steel plate culvert.

In order to achieve the object of the present invention, there are provided wire sensors arranged on an arcuate corrugated steel plate constituting a culvert to sense physical deformation of the arcuate corrugated steel sheet; A data logger for measuring a physical strain sensed by the wire sensors; A central server for receiving data measured by the data logger and monitoring it in real time and transmitting the information when an abnormal displacement occurs; And a portable terminal for receiving the information transmitted from the central server.

The arcuate corrugated steel sheet may include a plurality of unit corrugated steel sheets, a plurality of fixing bolts and fixing nuts connecting the unit corrugated steel sheets to each other, and the wire sensors may be connected to the fixing bolts.

Preferably, the wire sensors are disposed on the arch-shaped corrugated steel plate at intervals in the longitudinal direction of the culvert.

The data logger is preferably installed at one end of the arch-shaped corrugated steel sheet in the cowl length direction.

In addition, in order to achieve the object of the present invention, there is provided a method of manufacturing a cantilever-shaped corrugated steel sheet, comprising the steps of: sensing a physical change of the arched corrugated steel sheet in wire sensors disposed in the cantilevered corrugated steel sheet; Measuring a physical change sensed by the wire sensors in a data logger and transmitting the data to a central server; Monitoring data transmitted from the data logger at the central server; And transmitting the information to the administrator portable terminal when the data monitored by the central server is equal to or greater than a predetermined value.

The unit corrugated steel sheet 210 is formed in a rectangular plate shape having a uniform thickness and is formed of a curved surface and a plurality of mountains A and valleys B are formed at a predetermined interval. A plurality of unit corrugated steel plates 210 are connected in a circumferential direction to form an arch shape. At this time, the longitudinal direction of the crests and valleys of the unit corrugated steel sheet 210 is the same as the circumferential direction of the arcuate corrugated steel sheet 200. The two unit corrugated steel sheets 210 adjacent to each other are provided with through holes at both ends thereof, and the through holes of the two unit corrugated steel sheets 210 adjacent to each other are aligned with the fixing bolts 220 And the fixing nut 230 is fastened to connect two unit corrugated steel plates 210 adjacent to each other. Since the wire sensors 400 are connected to the fixing bolts 220 which are most easily generated in the deformation of the arcuate corrugated steel sheet 200, the deformation of the arcuate corrugated steel sheet 200 can be sensed sensitively.

The wire sensor 400 includes a sensing unit 410 and a wire unit 420 connected to the sensing unit 410. The sensing unit 410 may be a wire sensor. The wire sensors 400 are preferably disposed along the valleys or mountains of the arcuate corrugated steel sheet 200. Meanwhile, the wire sensors 400 may be fixed to the arc-shaped corrugated steel plate 200 by a separate fixing means.

It is preferable that the wire sensors 400 are disposed on the arch-shaped corrugated steel plate 200 at intervals in the longitudinal direction of the culvert.

The data logger 500 is connected to the wire sensors 400. A data logger 500 measures the physical deformation of the arcuate corrugated steel sheet 200 sensed by the wire sensors 400 over time. The data logger 500 includes a modem (not shown). The data logger 500 may further include broadcasting equipment (not shown) and video equipment (not shown).

7 is a flowchart showing an embodiment of a method of monitoring a corrugated steel plate culvert using a wire sensor according to the present invention.

7, in an embodiment of the method for monitoring a corrugated steel plate culvert using a wire sensor according to the present invention, first, in the wire sensors 400 disposed in the arcuate corrugated steel sheet 200 constituting the culvert, The step S1 of sensing the physical deformation of the corrugated steel sheet 200 proceeds. The wire sensor 400 senses the physical deformation of any one portion of the arcuate corrugated steel sheet 200 and senses the physical deformation of the entire arcuate corrugated steel sheet 200 through the plurality of wire sensors 400. The arcuate corrugated steel sheet 200 preferably includes a plurality of unit corrugated steel sheets 210 and a plurality of fixing bolts 220 and fixing nuts 230 for fixing the unit corrugated steel sheets 210 to each other. The wire sensors 400 are preferably connected to any one of the fixing bolts 220 of the fixing bolts 220 constituting the arc-shaped corrugated steel sheet 200 to sense physical deformation.

The physical deformation of the arc shaped corrugated steel sheet 200 is sensed through the wire sensors 400 and then the amount of physical change sensed by the wire sensors 400 is measured by the data logger 500 and the data is transmitted to the central server 600 Step S2 is proceeded. The data logger 500 measures the physical deformation of the set portions of the arcuate corrugated steel sheet 200 sensed in time by the wire sensors 400 and transmits them to the central server 600. The data logger 500 includes a modem.

After the data logger 500 transmits the data to the central server 600, the central server 600 monitors the data transmitted from the data logger 500 (S3).

When the data monitored by the central server 600 is equal to or higher than a predetermined value, the step S4 is performed to transmit the information to the administrator portable terminal 700. [ The central server 600 measures the physical deformation of the arcuate corrugated steel sheet 200 measured in time and transmits the measured data from the data logger 500 to the arcuate corrugated steel sheet 200 Lt; RTI ID = 0.0 > physical < / RTI > Then, information on a portion of the set portions of the arcuate corrugated steel sheet 200 in which the accumulated physical deformation amount is equal to or greater than a predetermined value is transmitted to the portable terminal 700 of the administrator. The central server 600 may further include storing data transmitted from the data logger 500.

When the amount of physical deformation accumulated in the set portions of the arcuate corrugated steel sheet 200 increases sharply, information on the amount of physical deformation is transferred to the portable terminal 700 of the administrator and at the same time, It is preferable to further include a step of operating the installed shut-off bar (not shown). As the shut-off bar is activated, the shut-off bar will block both entrances to the corrugated steel plate culvert.

Hereinafter, the function and effect of the corrugated steel plate culvert monitoring system and method using the wire sensor according to the present invention will be described.

First, the wire sensors 400 disposed on the portions of the arcuate corrugated steel sheet 200 detect the physical deformation of the set portions of the arcuate corrugated steel sheet 200 according to time. The physical deformation of the arcuate corrugated steel sheet 200 sensed by the wire sensors 400 is measured by the data logger 500 and the data is transmitted to the central server 600 in real time. The central server 600 can monitor the data transmitted from the data logger 500 and analyze the data to predict the physical deformation of the corrugated steel plate in the short and long term. The data is monitored by the central server 600 and the information is transmitted to the portable terminal 700 of the administrator when the data value reaches a predetermined value or more. The manager who receives the information from the portable terminal 700 can check the portion where the physical deformation value of the corrugated steel plate is generated by a predetermined value or more to take measures against the physical deformation. In the meantime, when the measured value is rapidly increased while monitoring by the central server 600, not only the information is transmitted to the portable terminal 700 of the administrator but also the shut-off bar provided on both sides of the entrance of the corrugated steel plate culvert is operated, The entrance and exit of the corrugated steel plate culvert are blocked, and the entrance and exit of the vehicle are controlled by the corrugated steel plate culvert.

As described above, according to the present invention, it is possible to predict the physical deformation of the corrugated steel plate culvert by short-term and short-term prediction by measuring the deformation of the corrugated steel plate culvert in real time using the wire sensor 400 and monitoring and analyzing the measured value, Maintenance of the structure including the culvert becomes convenient. In addition, it is possible to prevent disasters due to breakage of corrugated steel plate culvert by suggesting optimal measures for deformation of corrugated steel plate culvert.

The present invention is also applicable to the case where the wire sensors 400 are connected to the fixing bolts 220 connecting the unit corrugated steel plates 210 constituting the arcuate corrugated steel sheet 200, It is possible to accurately detect and measure the deformation of the arc-shaped corrugated steel sheet 200, thereby enhancing the reliability of monitoring.

In addition, the present invention monitors the data transmitted from the data logger 500 in the central server 600 and notifies the manager's portable terminal 700 of the data values, which are rapidly deformed among the monitored data values, It is possible not only to transmit the information but also to block the entrance of the corrugated steel plate culvert with the shutoff bar, thereby preventing the damage of the car and personal life due to the sudden breakage of the corrugated steel plate culvert.
