Hereinafter, a specific example of the pipe failure analysis method by the pipe management system 100 according to the first embodiment will be described with reference to the drawings. FIG. 4 is a diagram for explaining a pipe failure analysis method. FIG. 4A is a diagram showing a sewerage ledger for explaining the above-mentioned steps ST1 and ST2, and FIG. 4B is a diagram showing a sewerage ledger for explaining each step from the above-mentioned steps ST3 to ST6. Yes, FIG. 4C is a diagram showing a sewerage ledger for explaining step ST7 and step ST8 described above.

First, in step ST1 described above, the defect information acquisition unit 20 receives the defect information from the terminal device 2 as the defect information indicating the defect occurrence location A and the defect content information regarding the content of the defect that occurred in the defect occurrence location A. To get.

Next, in step ST2 described above, the pipe information acquisition unit 21 acquires the sewerage ledger shown in FIG. 4 as the pipe information from the storage device 11. The sewerage ledger includes the above-mentioned culvert map information, manhole information, culvert structure information and running water information.

FIG. 5 is a diagram for explaining the sewerage ledger in detail. The left side of FIG. 5 is a diagram for explaining the manhole information included in the sewerage ledger, and the right side of FIG. 5 is a diagram for explaining the pipe map information, the manhole information, the pipe structure information and the running water information included in the sewerage ledger in detail. It is a figure to do. As shown on the left side of FIG. 5 or the right side of FIG. 5, the manhole information acquired by the pipe information acquisition unit 21 indicates the ground height, overburden, manhole depth, manhole number, manhole symbol, and the like. As shown on the left side of FIG. 5 or the right side of FIG. 5, the pipe map information acquired by the pipe information acquisition unit 21 includes the manhole position, the positional relationship between manholes, and the positional relationship and connection relationship between the manhole and the pipe. Etc. are shown. Although not shown in FIG. 5, the culvert map information acquired by the culvert information acquisition unit 21 includes the positional relationship and connection relationship between the culvert and the building pit, and the inflow source of the culvert and a specific chemical substance. The positional relationship and connection relationship of the above shall also be shown. As shown on the left side of FIG. 5 or the right side of FIG. 5, the pipe structure information acquired by the pipe information acquisition unit 21 indicates the pipe diameter, pipe thickness, pipe bottom height, extension, slope, and the like of the pipe. As shown on the right side of FIG. 5, the flowing water information acquired by the pipe information acquisition unit 21 indicates the direction (arrow) of the flowing water in the pipe.

Next, in step ST3 described above, the investigation range determination unit 22 manages the pipe based on the defect occurrence location information and the defect content information acquired by the defect information acquisition unit 20 and the sewerage ledger acquired by the drainage information acquisition unit 21. Determine the investigation range B to be investigated in order to estimate the location of the cause of the defect in the culvert.

For example, if the cause of the problem is a clogged pipe, the water level in the upstream part from the clogged part in the pipe will be higher than the water level in the downstream part. Therefore, when the defect content information acquired by the defect information acquisition unit 20 indicates that the water level in the pipe is rising from the standard water level or the sewage is overflowing from the manhole connected to the pipe, the investigation range determination unit 22 determines the pipe. Based on the running water information acquired by the information acquisition unit 21, the range downstream from the defect occurrence location A in the pipe is determined as the investigation range B. Alternatively, when the defect content information acquired by the defect information acquisition unit 20 indicates a decrease in the water level in the drain from the standard water level, the investigation range determination unit 22 may determine the flow water information acquired by the pipe information acquisition unit 21. The range upstream from the defect occurrence point A in the pipe is determined as the investigation range B. Further, the larger the pipe diameter, the more the pipe tends not to be clogged. Therefore, the investigation range determination unit 22 is based on the pipe diameter indicated by the pipe structure information acquired by the pipe information acquisition unit 21. Therefore, a range including a pipe having a pipe diameter equal to or larger than a predetermined value may be excluded from the survey range B.

For example, if the cause of the malfunction is the inflow of sewage from the building pit connected to the pipe to the pipe, hydrogen sulfide generated from the sewage is heavier than air, so the connection point between the pipe and the building pit. There is a hydrogen sulfide odor downstream from. Therefore, when the defect content information acquired by the defect information acquisition unit 20 indicates a hydrogen sulfide odor from a manhole connected to the pipe, the investigation range determination unit 22 is based on the running water information acquired by the pipe information acquisition unit 21. , The range upstream from the defect occurrence point A in the pipe is determined as the investigation range B. Further, the survey range determination unit 22 may narrow the survey range B based on the connection point between the pipe and the building pit indicated by the pipe map information acquired by the pipe information acquisition unit 21.

For example, if the cause of the malfunction is the inflow of sewage containing a specific chemical substance into a pipe, the specific chemical substance is downstream from the connection point between the pipe and the inflow source of the sewage. Detected at high concentrations. Therefore, when the defect content information acquired by the defect information acquisition unit 20 indicates an increase from the standard value of the concentration of a specific chemical substance contained in the water in the pipe, the investigation range determination unit 22 acquires the pipe information. Based on the running water information acquired by the part 21, the range upstream from the trouble occurrence point A in the pipe is determined as the investigation range B. Further, the survey range determination unit 22 may narrow the survey range B based on the connection point between the pipe and the inflow source of sewage indicated by the pipe map information acquired by the pipe information acquisition unit 21.

For example, if the cause of the malfunction is the inflow of gas, which is a volatile chemical substance, into the pipe, the specific chemical substance is detected at a high concentration around the connection point between the pipe and the inflow source of the gas. To. Therefore, when the defect content information acquired by the defect information acquisition unit 20 indicates an increase in the concentration of gas, which is a volatile chemical substance, from the standard value, the investigation range determination unit 22 determines the pipe information acquisition unit. Based on the pipe map information acquired by 21, the range around the trouble occurrence point A in the pipe and around the connection point between the pipe and the gas inflow source is determined as the investigation range B.

Next, in step ST4 described above, the road map information acquisition unit 23 acquires road map information indicating a road on the ground from the storage device 11.
Next, in step ST5 described above, the travel route information generation unit 24 manages the road on the road based on the survey range B determined by the survey range determination unit 22 and the road map information acquired by the road map information acquisition unit 23. Generates driving route information related to the driving route to be traveled in order to acquire the environment information in the culvert. The terminal device 2 displays the travel route information generated by the travel route information generation unit 24 as an image.

FIG. 6 is a diagram showing travel route information displayed by the terminal device 2. The terminal device 2 has a travel route (measured) on which the vehicle 6 has traveled and a travel route (not yet) on which the vehicle 6 has not yet traveled among the travel routes D indicated by the travel route information generated by the travel route information generation unit 24. (Measurement) is displayed in a different color. When the vehicle 6 travels along the travel route D shown in FIG. 6, the vehicle communication device 4 receives the in-ditch environment information transmitted by the transmission unit 31 of the vertical hole lid 3 included in the travel route D. Then, the received environmental information in the pipe is transmitted to the environmental information acquisition unit 25 in the pipe.

Next, in step ST6 described above, the in-ditch environment information acquisition unit 25 acquires in-ditch environment information regarding the environment in the in-ditch of the investigation range B determined by the investigation range determination unit 22 from the vehicle communication device 4. do. The environmental information in the pipe is, for example, the water level in the pipe, the gas concentration in the pipe, the concentration of a specific chemical substance contained in the water in the pipe, and the like.

Next, in step ST7 described above, the cause occurrence location estimation unit 26 determines the cause occurrence location C in which the cause of the defect has occurred, based on the in-ditch environment information acquired by the in-ditch environment information acquisition unit 25. presume.

For example, if the cause of the malfunction is a clogged pipe, the water level in the pipe will be higher in the range upstream from the clogged part in the pipe, and the closer it is to the clogged part, the higher the water level will be. The water level in the downstream range is lower than the water level in the upstream range from the clogged point in the culvert. Therefore, the cause occurrence location estimation unit 26 determines the difference in water level between the two points in the pipe based on the water level in the pipe indicated by the environmental information in the pipe acquired by the environmental information acquisition unit 25 in the pipe. It is presumed that the location larger than the value of is the cause occurrence location C.

For example, if the cause of the malfunction is the inflow of sewage from the building pit connected to the culvert into the culvert, the concentration of hydrogen sulfide generated from the sewage in the culvert will be in the bill pit, which is the source of hydrogen sulfide. The closer it is, the higher it will be. Therefore, in the cause occurrence location estimation unit 26, the location having the highest concentration of hydrogen sulfide in the conduit indicated by the in-ditch environment information acquired by the in-ditch environment information acquisition unit 25 is the cause occurrence location C. I presume there is.

For example, if the cause of the malfunction is the inflow of sewage containing a high concentration of a specific chemical substance into the pipe, the concentration of the specific chemical substance contained in the water in the pipe is the source of the inflow of the sewage. The closer it is, the higher it will be. Therefore, the cause occurrence location estimation unit 26 has the highest concentration of the specific chemical substances contained in the water in the pipe, which is indicated by the environmental information in the pipe acquired by the environmental information acquisition unit 25 in the pipe. Is presumed to be the cause occurrence location C.

For example, if the cause of the malfunction is the inflow of gas, which is a volatile chemical substance, into the pipe, the concentration of gas in the pipe becomes higher as it is closer to the gas inflow source. Therefore, in the cause occurrence location estimation unit 26, the cause occurrence location C is the location having the highest concentration of the gas in the conduit indicated by the in-ditch environment information acquired by the in-ditch environment information acquisition unit 25. I presume.

Next, in step ST8 described above, the instruction information generation unit 27 operates on the device corresponding to the defect indicated by the defect information acquired by the defect information acquisition unit 20 at the cause occurrence location C estimated by the cause occurrence location estimation unit 26. Generate instructional information instructing you to do. The instruction information instructs the equipment installed in the ground to open / close the valve, change the height of the weir or the gate, or clean or remove dust, for example.

For example, it is assumed that a heater (not shown) is installed in advance at a place where clogging occurs frequently in the pipe. The instruction information generation unit 27 causes when the defect content information of the defect information acquired by the defect information acquisition unit 20 indicates a rise in the water level in the pipe from the standard water level or an overflow of sewage from the manhole connected to the pipe. At the cause occurrence location C estimated by the occurrence location estimation unit 26, instruction information is generated instructing the heater to perform an operation of raising the temperature in the pipe. As a result, for example, the temperature inside the culvert rises to about 50 degrees Celsius, and the animal fats and oils are melted to eliminate the clogging in the culvert.

For example, it is assumed that a water sampler (not shown) is installed in advance at the confluence of drainage from business establishments such as factories in pipes. When the defect content information of the defect information acquired by the defect information acquisition unit 20 indicates an increase from the standard value of the concentration of a specific chemical substance contained in the water in the pipe, the instruction information generation unit 27 causes the cause. At the cause occurrence location C estimated by the estimation unit 26, instruction information is generated instructing the water sampler to perform an operation of collecting a sample of water in the conduit. As a result, the manager of the culvert will appropriately eliminate the inflow of sewage containing a specific chemical substance into the culvert based on the sample.

For example, it is assumed that a damming machine is installed in advance at a place where clogging occurs frequently in the pipe. The weir stop machine is, for example, an electric valve, a gate, a weir, or the like. The instruction information generation unit 27 is concerned when the defect content information of the defect information acquired by the defect information acquisition unit 20 indicates a rise in the water level in the pipe from the standard water level or an overflow of sewage from the manhole connected to the pipe. It generates instruction information instructing the dam stop machine to perform an operation of damming the water flowing into the cause occurrence location C estimated by the cause occurrence location estimation unit 26. As a result, for example, the water level at the cause occurrence point C becomes low, and it becomes easy to perform the work for clearing the clogging.
