Description

  The present invention relates to a method for constructing a lining pipe line for rehabilitating an aged existing pipe by lining. In particular, the present invention relates to a method for constructing a lining pipe line having a system for measuring the amount of water in the pipe line.

  When the existing pipe is aged or damaged such as cracks or corrosion, the inner peripheral surface of the existing pipe is renewed. As a conventional method for rehabilitating existing pipes, various methods for covering an inner peripheral surface of an existing pipe with a synthetic resin lining material are known. One of them is the SPR (Sewage Pipe Renewal) method of backfill material injection that rehabilitates buried pipes without digging.

  In this rehabilitation method, for example, as described in Patent Documents 1 and 2, etc., a long strip member (profile) having flexibility is used. The band-shaped member has a rib having a T-shaped cross section on one side, and a joint portion having a convex shape and a concave shape is provided on one of both side edges.

  At the time of rehabilitation, a drum around which a belt-shaped member is wound is installed on the ground, and a pipe making apparatus is installed in an existing pipe. And a strip | belt-shaped member is continuously supplied to a pipe making apparatus from the said drum, and it winds helically within the existing pipe | tube. As for the strip | belt-shaped member made into the helical shape, mutually adjacent junction parts are joined by a pipe making apparatus, and become a tubular lining pipe. Further, an injection nozzle of a pipe making apparatus is inserted into the gap between the existing pipe and the lining pipe, and a backfill material such as reinforced mortar is injected and filled. Thereafter, the backfill material is cured after a certain curing period, and the existing pipe and the lining pipe are integrated, whereby the inner peripheral surface of the existing pipe is renewed with the lining pipe.

  By the way, in buried pipes such as sewer pipes, inflow water other than sewage such as rainwater and groundwater may also flow. For this reason, the water level and flow rate in the pipe line are repeatedly increased or decreased depending on the presence or absence of inflow water, and are often not constant. If the inflow water increases extremely, the water level and flow rate in the pipe line increase, which may lead to processing failure and insufficient processing capacity depending on the case.

  Therefore, in order to avoid such a situation, it is required to regularly measure and manage the water level or flow rate in the pipeline. For the measurement of the water level or flow rate in the pipeline, for example, a radio wave or ultrasonic water level meter installed above the water surface in the pipeline, or an ultrasonic flow meter that can be installed below the water surface It is conceivable to use a pressure sensor type water level meter, a capacitance water level meter, or the like.

  Among these, the radio wave type water level gauge and the ultrasonic water level gauge are limited in that they cannot be installed in a pipeline that may become full or the water level gauge may be submerged. In contrast, an ultrasonic flow meter, pressure sensor type or capacitance type water level meter can be installed in the water, but it requires cables for power supply and data communication to the sensor. However, there were many problems such as large installation work and easy maintenance.

  In recent years, a measurement system using a wireless tag (RFID tag) capable of non-contact information communication has been proposed. For example, Patent Document 3 describes a quantity measurement system in a container that includes a wireless tag attached to the container and a reader / writer device that communicates with the wireless tag. When the reader / writer device cannot communicate with the wireless tag, the reader / writer device determines that water is blocking communication, and detects that there is water around the wireless tag that cannot communicate. On the other hand, when communication with a wireless tag is possible, this is a mechanism for detecting that there is no water around the wireless tag capable of communication.

  However, this type of conventional measurement system mainly measures the amount of still water in the container, and cannot be applied as it is to the measurement of the amount of water that fluctuates in the buried pipe as described above. In addition, wireless tags are permanently installed without being washed away in harsh and humid environments where there is a large amount of running water, such as sewerage facilities, and chemical corrosion may occur due to various acids generated from sewage. In addition, no specific measures have been studied for enabling the wireless tag to withstand long-term use without causing functional deterioration.

  As mentioned above, although a method for newly establishing a water flow measurement system suitable for buried pipes has not been established, when maintenance is needed and rehabilitation is required, If a water volume measuring system can be provided, it is extremely efficient and practical. In particular, in the SPR method, since the pipe line of the existing pipe is covered with the lining pipe for rehabilitation, the radio tag is disposed between the existing pipe and the lining pipe to expose the radio tag to the sewage flow. It can be protected without any risk of loss or functional deterioration.

  Therefore, from the viewpoint of periodically measuring and managing the water level or flow rate in the pipeline, when performing construction to rehabilitate the inner peripheral surface of the existing pipe, a new water volume measurement system is provided in the pipeline, There has been a demand for a method for constructing a lining pipe line that enables smooth flow management after pipe rehabilitation.

  Therefore, the present invention has been made in view of the above circumstances, and the object of the present invention is between an identification tag provided in a pipeline and the identification tag located above the pipeline. A simple method for constructing a water volume measuring system that can withstand long-term use suitable for buried pipes such as sewage pipes and providing this water quantity measuring system in a lining pipe using a reader device that performs wireless communication in The aim is to provide a method for constructing a lining pipe that can be established and a new water measuring system can be installed at the same time as rehabilitation work for existing pipes.

  In order to achieve the above-mentioned object, the present invention provides an identification tag used for a water amount measurement system in a work process in which a lining pipe is formed and rehabilitated with respect to an existing pipe line that needs to be rehabilitated. In the construction process of the lining pipe, a plurality of identification tags are installed between the existing pipe and the lining pipe to provide a water amount measurement system.

  Specifically, the solving means of the present invention includes an identification tag provided in the pipeline with identification information, and a reader device that is located above the pipeline and performs wireless communication with the identification tag. The lining pipe construction method that can measure the amount of water in the pipe is used. The lining pipe construction method includes a lining pipe forming process, a curing process, and a tag arranging process. In the forming process, a plurality of ribs are erected on the long band-shaped base, and a band-shaped member having joints on both side edges of the band-shaped base is spirally wound while continuously supplying into the existing pipe, Adjacent joints are joined together to form a lining tube. In the curing step, the backfill material is injected into the gap between the existing pipe and the lining pipe and cured to integrate the existing pipe and the lining pipe. Further, in the tag disposing step, a plurality of the identification tags are disposed on the rib erected side of the band-shaped member so as to be close to the band-shaped base portion while being spaced apart from each other. Through these steps, a plurality of identification tags are provided between the existing pipe and the lining pipe.

  With such a specific matter, a lining pipe can be formed and rehabilitated inside an existing pipe, and an identification tag for a newly provided water amount measurement system can be provided in the pipe line. Here, since the identification tag is disposed on the rib erection side of the band-shaped member so as to be close to the band-shaped base in a state of being spaced apart from each other, the identification tag is disposed between the existing pipe and the lining pipe. It can be installed along the inner peripheral surface of. Therefore, only a lining pipe is interposed between the identification tag and the reader device, and wireless communication can be performed satisfactorily between the identification tag and the reader device. Further, since the identification tag is protected by the lining pipe without being exposed to corrosive running water flowing through the pipe line, it is possible to avoid causing loss or functional deterioration. In addition, since the identification tag does not affect the smoothness of the inner peripheral surface of the pipe, a smooth water flow can be maintained. Therefore, by providing the identification tag in the pipeline as described above, the identification information of the identification tag read by the reader device by performing wireless communication between the identification tag and the reader device in the rehabilitated lining pipeline Based on the above, it becomes possible to calculate the water level and flow rate of the water flowing inside the pipe.

  In the method for constructing the lining pipe line, the order of each of the forming process, the curing process, and the tag disposing process can be varied depending on the process contents of the tag disposing process.

  In other words, the first process sequence is performed in the order of the forming process, the curing process, and the tag disposing process. The second process sequence is performed in the order of the forming process, the tag arranging process, and the curing process. The third process sequence is performed in the order of the tag disposing process, the forming process, and the curing process.

  And as a tag arrangement | positioning process, the some structure described below is mentioned.

The strip-shaped member has a plurality of ribs erected along the longitudinal direction. In the tag disposing step, the tag in the tube axis direction opens at the end of the lining pipe and penetrates the rib of the strip-shaped member. The service holes are provided at a plurality of positions corresponding to the arrangement heights of the identification tags, and the identification tags are inserted and fixed in the tag holes. Such a tag placement process may be performed after the formation process and the curing process, or may be performed between the formation process and the curing process (that is, in the case of the first or second process sequence).

  That is, after forming the lining pipe in the existing pipe through the forming step, a tag hole for disposing the identification tag is opened in the pipe axis direction along the belt-like member from the end of the lining pipe. In this case, for the lining pipe formed in the existing pipe, a tag hole is provided with an appropriate length in the pipe axis direction from the opening end of the lining pipe. Then, an identification tag is inserted from the tag hole opened at the end of the lining pipe, and the identification tag is provided between the existing pipe and the lining pipe. By arranging the tag holes in a plurality of locations in accordance with the height of the identification tag, a plurality of identification tags can be arranged at different height positions. Further, since the tag hole is not provided on the inner peripheral surface of the lining pipe, it does not affect the smoothness and water stoppage of the inner peripheral surface. Thus, the identification tag is installed between the existing pipe and the lining pipe, and the surface of the identification tag is covered and protected.

Further, in the tag placement step, a plurality of tag holes are formed on the inner peripheral surface of the lining pipe corresponding to the location and size of each identification tag, and the identification tag is fitted into each tag hole. Thereafter, the tag hole may be closed and fixed with a closing member having the same shape as the tag hole. Such a tag arrangement process may be performed after the curing process or performed between the formation process and the curing process (that is, in the case of the first or second process sequence).

  That is, since the lining pipe is formed in the existing pipe through the forming process, the tag hole for arranging the identification tag can be opened directly from the inside of the lining pipe to the inner peripheral surface of the lining pipe. In this case, since work can be performed from the inside of the lining pipe, a required number of tag holes are provided at necessary locations according to the situation of the construction site, and the identification tag is fixed to each tag hole. Can cope with various pipe line conditions.

The strip-shaped member is provided with a plurality of ribs extending in the longitudinal direction, and the tag disposing step includes a tag hole through which the linear member is inserted into one place on the inner peripheral surface of the lining pipe. A linear member connecting a plurality of identification tags is introduced from the end of the lining pipe between the ribs of the belt-like member, and is inserted through the ribs and led out from the tag hole, and the identification tag It is good also as a structure arrange | positioned between the ribs of a strip | belt-shaped member. Such a tag placement process is performed between the formation process and the curing process (that is, the second process order).

  In this case, the end face of the lining pipe formed in the existing pipe has a cut end surface of the belt-like member, so that a plurality of identification tags are inserted between the ribs of the belt-like member between the lining pipe and the existing pipe. It will be arranged. The plurality of identification tags are connected by a linear member. The linear member is inserted from the end of the lining pipe and is spirally introduced into the inside through the ribs. Further, by pulling out the linear member from the tag hole provided in the lining pipe, a plurality of identification tags connected to the linear member are disposed at predetermined positions. In such a configuration, it is not necessary to individually arrange a plurality of identification tags, and a plurality of identification tags can be arranged in a lump, so that the number of work steps can be reduced and construction can be performed more easily.

  In such a tag disposing step, more preferably, a tensile force is applied to the linear member inserted between the ribs of the strip-shaped member so that each identification tag is brought into close contact with the strip-shaped base portion.

  Accordingly, each identification tag can be held between the ribs of the band-shaped member, and only the band-shaped base of the band-shaped member constituting the lining pipe is interposed between the identification tag and the reader device. Wireless communication can be satisfactorily performed with the apparatus.

In addition, a plurality of ribs are erected along the longitudinal direction of the belt-shaped member, and as the tag disposing step, an identification tag is disposed between the ribs of the belt-shaped member, and the band is contacted with the identification tag. A configuration may be adopted in which a pressing member in contact is mounted between the ribs, and the identification tag is held by the belt-shaped member. Such a tag disposing step may be performed before the forming step, or may be performed between the forming step and the curing step (that is, in the case of the second or third order form).

  That is, an identification tag is previously disposed on the band-shaped member before the lining pipe is formed. In this case, the plurality of identification tags are directly arranged between the ribs of the belt-like member with a space between each other. Further, a pressing member for fitting the identification tag between the ribs is fitted between the ribs. Thereby, a lining pipe | tube can be formed in the state which hold | maintained the identification tag to the strip | belt-shaped member.

  Further, after the lining pipe is formed, it is possible to install the identification tag between the ribs of the band-shaped member constituting the lining pipe and insert the pressing member between the ribs. . In this case, the identification tag may be fixed in advance between the ribs of the belt-shaped member, or may be connected to the linear member and introduced between the ribs.

  In these configurations, the identification tag held between the ribs of the band-shaped member is sandwiched and covered by the band-shaped member and the pressing member. Therefore, not only can the identification tag be stably fixed by the pressing member, but also it can be protected from external forces, impacts, and the like when the lining pipe is formed or when the backfill material is injected.

In addition, a plurality of ribs are erected along the longitudinal direction of the belt-shaped member, and a pressing member provided with a plurality of identification tags is disposed between the ribs of the belt-shaped member in the tag arranging step. The identification tag may be attached to the belt-shaped member. Such a tag disposing step may be performed before the forming step, or may be performed between the forming step and the curing step (that is, in the case of the second or third order form).

  By adopting such a method, the number of work steps can be reduced, and a plurality of identification tags can be held between the ribs of the belt-like member more easily.

  Moreover, in this tag arrangement | positioning process, it is desirable for the said pressing member to be the elongate material which bent the strip | belt board material which has rigidity in groove shape.

  Thus, the pressing member can be easily pushed into the belt-like member in a spiral shape from between the ribs at the end, and the protection function of the identification tag when mounted between the ribs can be exhibited.

  In the present invention, a process of disposing an identification tag of the water amount measurement system is incorporated in each work process for rehabilitating the pipeline, and a plurality of identification tags are provided between the existing pipe and the lining pipe. . Therefore, at the same time as the rehabilitation work for the existing pipe, an identification tag can be newly installed by a simple method with good workability, and such an identification tag and a reader device that performs wireless communication between the identification tag and A lining pipe line can be provided with a water volume measuring system using In addition, the installed identification tag is covered and protected by the lining tube, so even in a corrosive and humid environment, the wireless tag can be permanently installed without being washed away, resulting in functional deterioration. Therefore, it becomes possible to provide a water amount measurement system that can withstand long-term use.

  Hereinafter, the construction method of the lining pipe line which concerns on embodiment of this invention is demonstrated, referring drawings.

-Explanation of water volume measurement system-
In the description of the construction method of the lining pipe line according to the present invention, first, an outline of a water amount measurement system applied to the lining pipe line will be described.

  Drawing 1 is an explanatory view showing typically a section of a pipe provided with a water quantity measuring system concerning an embodiment.

  As shown in the drawing, the existing pipe 21 in the ground is rehabilitated by the lining pipe 1. A plurality of identification tags 3 (identification tags 3a to 3e) are disposed in the pipe line 1a. Each identification tag 3 is a wireless tag (RFID tag) to which unique identification information is assigned, and is arranged along the inner peripheral surface of the pipe line 1a. In addition, the water amount measurement system includes a reader device 4 that performs wireless communication with each identification tag 3, and the water level of water flowing in the pipe 1 a based on the identification information of the identification tag 3 read by the reader device 4. And a data processing device 5 for calculating the flow rate. Further, an output device 6 that outputs information read by the reader device 4 is provided.

  The installation place of the identification tag 3, the reader device 4, the data processing device 5, and the output device 6 is preferably in the vicinity of a manhole 22 where workers can go in and out so as to facilitate maintenance after installation. Particularly, the installation position of the reader device 4 needs to be a height position at which wireless communication is possible with the identification tag 3 of the pipe line 1a so that the reader apparatus 4 is not submerged even when the water volume increases. Therefore, as shown in the drawing, it is preferable to install the reader device 4 on the inner wall surface 221 of the manhole 22 above the lining pipe 1. These reader device 4, data processing device 5, and output device 6 are connected to each other by a cable 7 or the like.

  FIG. 2 is an explanatory view schematically showing a cross section intersecting the water flow direction of the pipe line 1a. The identification tag 3 (identification tags 3a-3e) is arrange | positioned in a different height position along the internal peripheral surface of the pipe line 1a. Among these, the identification tags 3 d and 3 e are located below the water surface W and cannot perform wireless communication with the reader device 4. On the other hand, since the identification tags 3 a to 3 c are located above the water surface W, communication with the reader device 4 can be performed.

  In this case, the reader device 4 shown in FIG. 1 receives communication signals from the identification tags 3 a to 3 c, reads each identification information, and outputs it to the data processing device 5. While the data processing device 5 recognizes the identification information of the identification tags 3a to 3c, the identification information of the identification tags 3d and 3e is not input, so that the water surface W is between the identification tag 3c and the identification tag 3d. recognize. Then, the position of the water surface W between the identification tag 3c and the identification tag 3d is transmitted to the host system via the output device 6 as the water level of the pipeline 1a.

  Here, the reader device 4 reads the identification information of the identification tag 3 at a predetermined time interval, calculates the average water level based on the identification information received by the data processing device 5, and transmits it from the output device 6 to the host system. It is good also as composition to do.

  Furthermore, as shown in FIG. 2, based on the position of the water surface W recognized from the identification information of the identification tag 3 read by the reader device 4, the wetted edge S and the water flow cross-sectional area A of the pipeline 1 a are calculated, It is also possible to calculate the average water flow velocity V using the following Manning equation.

  Here, the wet side S indicates the length in the circumferential direction of the portion in contact with running water on the inner peripheral surface (inner diameter) of the pipe line 1a. R is the hydraulic mean water depth and I is the water surface gradient. Further, n is a Manning roughness coefficient, which is a coefficient specific to the material of the inner peripheral surface of the pipe line 1a. As the roughness coefficient n of Manning, for example, 0.014 is used for the concrete surface, and 0.009 is used for the resin-coated surface.

  The data processing device 5 may be configured to obtain the average flow velocity V according to the Manning equation, calculate the flow rate per unit time, and transmit the flow rate data to the host system via the output device 6. Therefore, in the host system, it is also possible to construct a sewer management system that obtains flow rate data from a plurality of output devices 6 and performs a flow rate analysis of the sewer network in real time to predict a downstream flow rate. .

  Further, in such a water amount measurement system, the data processing device 5 is omitted, and the identification information of the identification tags 3a, 3b, and 3c read by the reader device 4 is directly transmitted to the upper system via the output device 6, and the higher system A configuration of executing data processing is also possible. On the other hand, in a large-scale sewer constituted by pipes having various shapes and pipe diameters, the data processing apparatus 5 may be provided to reduce the data processing burden of the host system.

  FIG. 3 is a functional block diagram of the water amount measurement system according to the present embodiment. As described above, this water amount measurement system includes the identification tag 3, the reader device 4, the data processing device 5, and the output device 6.

  The identification tag 3 includes a control circuit 31, an antenna 32, and a memory 33. The identification tag 3 generates an electromotive force in the antenna 32 by the electromagnetic field of the radio wave transmitted from the reader device 4, and drives the control circuit 31 and the memory 33. At this time, no electromotive force is generated unless the receiving surface of the antenna 32 is arranged to form a predetermined solid angle with respect to the propagation direction of the radio wave transmitted from the reader device 4. Therefore, in order to operate the identification tag 3, it is necessary to arrange the identification tag 3 so that the solid angle of the receiving surface of the antenna 32 is not at least zero with respect to the propagation direction of the radio wave transmitted from the reader device 4.

  In the memory 33 of the identification tag 3, unique identification information for identifying the identification tag 3 from other identification tags is stored. The control circuit 31 is driven by the electromotive force generated by the antenna 32, reads identification information from the memory 33, and causes the antenna 32 to emit a modulated radio wave carrying the identification information.

  The reader device 4 includes a control circuit 41 and an antenna 42. The control circuit 41 transmits a radio wave for driving the identification tag 3 from the antenna 42. In addition, the control circuit 41 causes the antenna 42 to receive a radio wave transmitted from the identification tag 3 and extracts identification information from the received signal. Further, the control circuit 41 converts the extracted identification information into a code capable of data processing and sends it to the data processing device 5.

  The data processing device 5 is a microcomputer including a CPU 51, a memory 52, and an interface circuit 53. The data processing device 5 receives the identification information of the identification tag 3 from the reader device 4 via the interface circuit 53, and can communicate with the reader device 4 in the identification tag 3 arranged on the inner peripheral surface of the pipe line 1a. The identification tag 3 (for example, identification tags 3a-3c) located above the water surface W is recognized.

  The memory 52 stores the arrangement form of the identification tag 3, and determines the water level in the pipe line 1 a based on the arrangement of the identification tag 3 above the water surface W. Furthermore, the data processing device 5 calculates the flow rate of the water flowing through the pipeline 1a using the Manning equation based on the determined water level. Parameters such as the inner diameter R and the water surface gradient I of the pipe line 1 a and the Manning roughness coefficient n are stored in the memory 52.

  The data processing device 5 also functions as a controller that controls the reader device 4 and the output device 6. A program for controlling these devices is stored in the memory 52.

  For example, the data processing device 5 sends the determined water level and flow rate data to the output device 6 and controls the communication controller 61 to send it to the host system. The output device 6 includes a communication controller 61 and a microwave transmission / reception unit 62. The transmission / reception unit 62 is controlled by the communication controller 61 and performs data communication with a host system via a base station of a mobile phone.

  In such a water amount measurement system, the output device 6 can be configured to be connected to a host system via an optical fiber communication network as an optical line terminating device (OUN) for optical fiber communication. Further, as described above, the system does not include the data processing device 5, and the communication controller 61 of the output device 6 controls the reader device 4, and the identification information read by the reader device 4 is transferred from the output device 6 to the host system. It is also possible to adopt a configuration for transmission.

  In addition, in order to prevent flooding due to sudden increase of water, a warning water level or a warning flow rate is set in advance, and when the water level or flow rate calculated by the data processing device 5 exceeds the warning water level or the warning flow rate, an alarm signal Can be output from the output device 6 to the host system. As a result, it is possible to construct a host system equipped with safety measures against natural disasters such as floods.

-Example of identification tag arrangement on lining pipe line-
FIG. 4 is a cross-sectional view showing an example of the arrangement of identification tags, which is an example of a lining pipe line provided with a water amount measurement system.

  The identification tags 3 a to 3 e are installed between the lining pipe 1 and the existing pipe 21 in the vicinity of the lining pipe 1 in the pipe line 1 a whose inner peripheral surface is renewed by the lining pipe 1. Each identification tag 3a-3e is arrange | positioned at the height corresponding to the predetermined water level set at equal intervals of the height W. As shown in FIG. Thereby, it becomes the structure which can detect the water level of the water which flows through the pipe line 1a by making height W into 1 unit.

  For example, when the reader device 4 is able to acquire identification information by communicating with all of the identification tags 3a to 3e, the data processing device 5 determines that the water level is a 1 W position. In addition, when the reader device 4 communicates with the identification tags 3a to 3d to acquire identification information, the data processing device 5 determines that the water level is a 2W position.

  5 and 6 are perspective views schematically showing the arrangement form of the identification tag 3. In FIG. 5, the virtual cross section orthogonal to the water flow direction of the water which flows through the existing pipe 21 is shown, and the identification tags 3 are arranged in an annular shape along the circular cross section. On the other hand, FIG. 6 shows a virtual cross section having a predetermined inclination with respect to the water flow direction, and the identification tags 3 are arranged along an elliptical cross section.

  In the arrangement form shown in FIG. 6, the length of the circumferential surface to be arranged is longer than in the example of FIG. For this reason, in the arrangement | positioning form of FIG. 6, more identification tags 3 can be arranged. That is, compared with the example arrange | positioned along the circular cross section shown in FIG. 5, it becomes possible to detect a water level with narrower width W, and can improve a detection precision.

-Construction method of lining pipe line-
Next, the construction method of a lining pipe line provided with the above water quantity measurement systems is demonstrated.

  In the construction of the lining pipe, a plurality of identification tags 3 are installed between the lining pipe 1 and the existing pipe 21 by at least the following three processes, that is, a forming process, a curing process, and a tag arranging process. To do. Then, wireless communication is performed between the reader device 4 positioned above the pipe line 1a in which the identification tag 3 is provided and each identification tag 3 to enable water volume measurement.

(Formation process)
In this step, a long strip member is wound in an existing pipe to form a lining pipe.

  Fig.7 (a) is sectional drawing which shows an example of a strip | belt-shaped member, FIG.7 (b) is sectional drawing which shows a mode that the strip | belt-shaped members were joined. The band-shaped member 10 is a member formed in a long band shape from a synthetic resin material such as hard vinyl chloride, and a plurality of ribs 12 are erected along the longitudinal direction on one side of the flat band-shaped base 11. Further, on both side edge portions of the belt-like base portion 11, joint portions 13 are formed so as to overlap with each other and engage with each other. In the belt-like member 10, a long reinforcing member 14 processed into a W-shaped cross section is fitted between adjacent ribs 12 as necessary.

  By winding the belt-like member 10 in a spiral manner in the existing pipe, the adjacent joints 13 and 13 are joined to each other as shown in FIG. 7B. Thereby, the strip | belt-shaped member 10 becomes a tubular shape and comprises the lining pipe | tube 1. FIG.

  Fig.8 (a) is sectional drawing which shows the other example of a strip | belt-shaped member, FIG.8 (b) is a perspective view of the junction part of the strip | belt-shaped member. As shown in FIG. 8A, the belt-like member 100 may be joined via a connector 110. The illustrated belt-like member 100 is also a member that is formed in a long shape with a plurality of ribs 112, and is provided with concave joint portions 113 at both side edges. In the connector 110, joint convex portions 115, 115 that can be joined to the joint portion 113 of the belt-like member 100 are continuously formed along the longitudinal direction. This connector 110 is fitted over the joining portions 113 and 113 of the adjacent belt-like members 100 and joins them.

  In the step of forming the lining pipe 1, as shown in FIG. 9, the belt-like member 10 is continuously supplied from the ground drum 82 to the pipe making apparatus 81 installed at the end of the existing pipe 21. The pipe making apparatus 81 forms the lining pipe 1 by winding the belt-like member 10 in a spiral shape and joining the joining portions 13 (see FIG. 7) adjacent to each other. Moreover, the lining pipe | tube 1 can also be formed with what is called a self-propelled type pipe manufacturing apparatus 83 installed in the inside of the existing pipe | tube 21, as shown in FIG. The pipe making device 83 is driven by the hydraulic oil supplied from the hydraulic unit 84, and the hydraulic unit 84 is driven by the power supplied from the generator 85.

(Curing process)
In this step, a back-filling material 23 such as high-strength mortar is injected and filled in the gap between the formed lining pipe 1 and the existing pipe 21. The injection of the backfill material 23 is, for example, a method of supplying the backfill material 23 to an injection nozzle connected to the pipe making device 83 and injecting from the opening end of the lining pipe 1, or injection established at a plurality of locations of the lining pipe 1 A method of injecting from the holes can be selected as appropriate. Further, the backfill material 23 can be injected even after the lining pipe 1 is formed or simultaneously with the forming operation of the lining pipe 1.

  Thus, after filling and filling the backfill material into the gap between the inner peripheral surface of the existing tube 21 and the outer peripheral surface of the lining tube 1, the backfill material 23 is cured after a certain curing period. Thereby, even if the existing pipe 21 and the lining pipe 1 are integrated, even if the strength of the existing pipe 21 is lowered, the lining pipe 1 and the backfill material 23 can ensure high strength.

(Tag placement process)
In this step, a plurality of identification tags 3 to which unique identification information is assigned are disposed in a new pipeline 1a formed in the existing pipe 21 in order to provide the above-described water amount measurement system. In addition, the identification tag 3 is placed on one side (rib standing side) of the belt-like member 10 so that wireless communication is suitably performed between the reader device 4 disposed above the pipe line 1a and the identification tag 3. Arranged close to the base 11. Further, a plurality of identification tags 3 are arranged in a state of being spaced apart from each other.

  There are a plurality of variations in this tag placement step. Therefore, in the following embodiment, a detailed description of the tag placement process will be given.

<Embodiment 1>
First, Embodiment 1 which concerns on the construction method of a lining pipe line is demonstrated, referring FIGS. 11-13.

  FIG. 11 is an explanatory view showing one step of the lining pipe construction method according to the first embodiment, and schematically showing the cross section of the existing pipe together with the half cross section of the lining pipe. Moreover, FIG. 12 is the elements on larger scale of the pipe cross section of FIG. 11, and FIG. 13 is the elements on larger scale of the pipe cross section after construction completion.

  In addition, in the construction method of the lining pipe line which concerns on Embodiment 1-4 demonstrated below, about the already-explained description member etc., the description is abbreviate | omitted by attaching | subjecting the code | symbol same as the above, and is peculiar to each embodiment. The point will be described in detail.

  In this embodiment, the construction of the lining pipe line is performed in the order of the forming process, the tag arranging process, and the curing process.

  Among them, the forming process and the curing process are as described above, but the tag disposing process is characterized in that it is performed using a linear member 16 in which a plurality of identification tags 3 are connected as shown in FIG. Have.

  That is, the lining pipe 1 having a length corresponding to the pipe length to be rehabilitated is formed inside the existing pipe 21 through the forming process. A tag hole 15 is opened at one place on the inner peripheral surface of the lining pipe 1. The tag hole 15 is provided in the vicinity of the location where the plurality of identification tags 3 are to be arranged on the inner peripheral surface of the lining pipe 1.

  As shown in FIGS. 11 and 12, the linear member 16 has strength and flexibility, and has a thickness that is inserted between the ribs of the belt-like member 10. As the linear member 16, for example, a cord, a cable, a rope, or the like made of various fiber materials, a metal wire, a chain, or the like can be used, but is not limited thereto. The tag hole 15 may be of a size that allows the linear member 16 to be inserted, and an extremely small hole is sufficient. A necessary number of identification tags 3 attached to the pipe line 1a is connected to the linear member 16 with an interval corresponding to the arrangement interval.

  As shown in FIG. 11, the open end 1 b of the lining pipe 1 is open to the manhole 22. A linear member 16 in which a plurality of identification tags 3 are connected is inserted between the ribs 12 from the end face 10a of the belt-like member 10 appearing at the opening end 1b. FIG. 12 shows a state in which the linear member 16 is inserted between the ribs 12 of the strip member 10 constituting the lining pipe 1. By inserting the linear member 16 between the ribs 12, the linear member 16 can be spirally disposed on the outer peripheral surface of the lining pipe 1. The distal end portion of the linear member 16 is pulled out from the tag hole 15 provided in the lining pipe 1 into the pipe line 1a.

  Next, a tensile force is applied to the linear member 16 inserted between the ribs 12. When a tensile force is applied, as shown in FIG. 12, the linear member 16 and the identification tag 3 connected to the linear member 16 are in close contact with the surface of the strip-shaped base 11.

  Next, in a state where the linear member 16 is disposed between the ribs 12, the process proceeds to the curing step. That is, in a state where the linear member 16 and the identification tag 3 are in close contact with the outer peripheral surface of the lining pipe 1 (the surface of the strip-shaped base portion 11), the gap between the inner peripheral surface of the existing pipe 21 and the outer peripheral surface of the lining pipe 1 is set. The backfill material 23 is injected and cured. Further, the linear member 16 led out from the tag hole 15 is cut and removed.

  Thereby, as shown in FIG. 13, the existing pipe | tube 21 and the lining pipe | tube 1 are integrated, and a composite pipe | tube is formed. Since the identification tag 3 is fixed to the outer peripheral surface of the lining pipe 1, the band-shaped base portion 11 of the band-shaped member 10 constituting the lining pipe 1 is only interposed between the identification tag 3 and the reader device 4. Therefore, wireless communication can be performed satisfactorily between the identification tag 3 and the reader device 4.

  Further, in the tag arranging step, it is not necessary to individually arrange the plurality of identification tags 3 with respect to the lining pipe 1, and the plurality of identification tags 3 can be arranged in a lump. Therefore, the number of work steps involved in the tag placement process is small, and construction can be performed very simply.

  In addition, you may make it incorporate the tag arrangement | positioning process using such a linear member 16 in the middle of a formation process. That is, during the pipe making of the lining pipe 1, the pipe making operation is temporarily interrupted, and the linear member 16 connected to the identification tag 3 is disposed on the belt-like member 10 supplied to the pipe making apparatus. Thereafter, the pipe making operation is resumed, the linear member 16 is disposed, and the belt-like member 10 is spirally wound to form the lining pipe 1. Thereby, the linear member 16 can be easily disposed on the outer peripheral surface of the lining pipe 1. Then, after completing the pipe-making work of the lining pipe 1, it is preferable to apply a tensile force to the linear member 16 and bring the identification tag 3 into close contact with the belt-like base portion 11 as described above.

<Embodiment 2>

The holding member 17 is made of a long material obtained by bending a rigid synthetic resin or metal band plate material into a groove shape. The pressing member 17 is formed to have a width dimension that fits between the ribs 12 of the belt-like member 10, and has a configuration in which a side edge is locked and fixed to the tip of the rib 12 having a substantially T-shaped cross section.

  In this case, a plurality of identification tags 3 are disposed directly between the ribs 12 of the band-shaped member 10 with a space between each other, and then a pressing member 17 is fitted between the ribs 12 to contact the identification tag 3. Let By providing the pressing member 17 with an appropriate elastic force, the identification tag 3 can be pressure-bonded to the band-shaped base 11 when the pressing member 17 is mounted between the ribs 12. In addition, all of the plurality of identification tags 3 can be held on the belt-like member 10 by one pressing member 17, which is efficient.

  Next, the forming process of the lining pipe 1 is performed in a state where the plurality of identification tags 3 are held on the belt-like member 10. As shown in FIG. 14, the plurality of identification tags 3 held between the ribs 12 of the band-shaped member 10 are sandwiched and covered by the band-shaped member 10 (band-shaped base portion 11) and the pressing member 17. For this reason, the identification tag 3 can be stably fixed by the pressing member 17, and can be protected from an impact at the time of manufacturing the lining pipe 1 or injecting the backfill material.

  Further, as the pressing member 17 of the identification tag 3, a member having a relatively high bending rigidity in the length direction may be used. In this case, the pressing member 17 can be mounted not only by being fitted between the ribs 12 as described above, but also by being inserted or pushed into the ribs 12 from the end of the belt-like member 10. It is. For this reason, it becomes possible to perform the construction of the lining pipe 1 in the order of the forming process, the tag arranging process, and the curing process.

  That is, the lining pipe 1 is first formed in the existing pipe 21 (forming process). Thereafter, the pressing member 17 is spirally inserted from the end of the lining pipe 1, and a space for disposing the identification tag 3 is provided in the band-shaped member 10. Next, as shown in the first embodiment, a plurality of identification tags 3 are connected to the linear member 16, and the linear member 16 is introduced into the space between the belt-like member 10 and the pressing member 17 (tag arrangement). Installation process). As a result, the identification tag 3 can be held on the belt-like member 10 and the identification tag 3 can be protected.

  In addition, a plurality of identification tags 3 may be attached between the ribs 12 of the belt-like member 10 or inserted from the end in a state where a plurality of identification tags 3 are bonded to the pressing member 17 with a gap. By adopting such a method, the number of work steps can be reduced, and the plurality of identification tags 3 can be held between the ribs 12 of the belt-like member 10 more easily.

<Embodiment 3>
Next, Embodiment 3 of the construction method of a lining pipe line is demonstrated, referring FIG.15 and FIG.16. FIG. 15 is a cross-sectional view illustrating a tag disposing step of the lining pipe construction method according to the third embodiment, and FIG. 16 is a partial cross-sectional view in the pipe axis direction of the lining pipe of FIG.

  In the tag disposing step of the present embodiment, a tag hole 15 is provided in the tube axis direction that opens to the open end 1b of the lining tube 1 and penetrates the rib 12 of the belt-like member 10. The opening of the tag hole 15 may be before the curing process or after the curing process as long as it is after the forming process of the lining pipe 1. As shown in the figure, for the lining pipe 1 formed inside the existing pipe 21, a tag hole 15 is opened in the pipe axis direction from the opening end 1 b of the lining pipe 1 along the strip-shaped base 11. The tag hole 15 is provided so as to penetrate the rib 12 and the reinforcing member 14.

  The opening operation of the tag hole 15 is preferably performed from the viewpoint of workability using a processing tool such as an electric drill, an air driven drill, or a chipper. It is also possible to manually open the tag hole 15 using an appropriate tool such as a chisel. FIG. 16 shows a state in which the tag hole 15 is opened after the curing process, and the tag hole 15 is provided through the cured backfill material 23.

  Further, as shown in FIG. 15, the tag holes 15 are provided at a plurality of locations in the circumferential direction of the lining pipe 1 in accordance with the arrangement height of each identification tag 3. The length of the tag hole 15 is set to an appropriate length in the tube axis direction from the open end 1b of the lining tube 1 in accordance with the location of each identification tag.

  Next, the identification tags 3... 3 are inserted into the opened tag holes 15. At this time, the identification tag 3 may be simply pushed into the tag hole 15, or the identification tag 3 may be adhered to the tag hole 15 using an adhesive or a double-sided tape.

  Thus, a plurality of identification tags 3 can be installed between the inner peripheral surface of the existing pipe 21 and the outer peripheral surface of the lining pipe 1. Since the tag hole 15 does not provide a hole in the inner peripheral surface of the lining pipe 1, the tag hole 15 does not affect the smoothness, water stoppage, and the like of the inner peripheral surface of the pipe 1 a.

  When the tag placement step is performed before the curing step, after inserting and arranging the identification tags 3... 3 into the tag holes 15... 15, the backfill material 23 is placed in the gap between the lining pipe 1 and the existing pipe 21. Inject and fill. As a result, the backfill material 23 is also filled in the tag hole 15 and the identification tag 3 is fixed to the outer peripheral surface of the lining pipe 1.

  In addition, when the tag placement step is performed after the curing step, a form as shown in FIG. 16 is formed, and a mortar filler similar to the backfill material 23 is inserted into the tag hole 15 into which the identification tag 3 is inserted, Alternatively, an epoxy resin filler, a silicon filler, or the like is filled and the tag hole 15 is closed to ensure water tightness. Thereby, the identification tag 3 can be installed between the existing pipe 21 and the lining pipe 1, and can be covered and protected by the lining pipe 1.

In this embodiment, the tag placement process is performed between the formation process and the curing process or after the curing process. That is, for the lining pipe 1 formed in the existing pipe 21 through the forming process, the tag hole 15 for arranging the identification tag is opened directly on the inner peripheral surface of the lining pipe 1 from the inside of the pipe line 1a. .

  Specifically, before injecting the backfilling material 23 between the lining pipe 1 and the existing pipe 21 (see FIG. 17) or after injecting and curing the backfilling material 23, the inner peripheral surface of the lining pipe 1 The tag hole 15 is opened in For the opening work of the tag hole 15, a processing tool such as an electric drill, an air driven drill, or a chipper can be used. As shown in FIG. 17, it is sufficient that the size of the tag hole 15 is approximately equal to that of the identification tag 3.

  The identification tags 3 are fitted into the tag holes 15, respectively, and are closed and fixed by the closing members 18 having the same shape as the tag holes 15. The closing member 18 is a plate-like member formed of, for example, the same synthetic resin material as that of the belt-like member 10, and is preferably pasted on the identification tag 3 in advance and integrated. Further, the identification tag 3 and the closing member 18 are fixed to the strip member 10 provided with the tag hole 15 by adhesion.

  When the tag placement step is performed before the curing step, the identification tag 3 is fitted into the tag hole 15 and closed, and then the backfill material 23 is injected between the lining pipe 1 and the existing pipe 21. Thereby, the identification tag 3 and the closing member 18 are also integrally fixed to the lining pipe 1 (curing process). If the tag placement process is performed after the curing process, the identification tag 3 and the closing member 18 are bonded and fixed to the tag hole 15 to complete the process. In addition, in order to further improve the water tightness at the joint between the tag hole 15 and the blocking member 18, it is preferable to seal the joint. Sealing can be performed by welding using a synthetic resin, filling with a sealing material, or bonding with an adhesive.
