To be formed.

  Next, a cleaning method using the cleaning apparatus 1 according to the first embodiment configured as described above will be described with reference to FIGS. First, the scraping jig 20, the wiping jig 30 and the cleaning jig 40 are connected to the conduction jig 10, and the cable K extending from one end side of the pipe line P to each cable insertion hole 11, 21, 31, 41. Is inserted. At this time, each jig is attached to the cable K so that the conduction jig 10 is positioned on the front side in the pulling direction. Then, the pulling wire 7B is connected to the conduction jig 10, and the pulling device 7 pulls these jigs from one end of the pipeline P toward the other end. At the same time, the suction / separation / recovery means 3 sucks the inside of the pipe P from the other end side of the pipe P, and separates and collects the suction material at that time. Further, at that time, cleaning water or the like (mixed with a cleaning agent if necessary) is introduced into the pipe P by being mixed with the air flow by the cleaning water introducing means 8 from one end side of the pipe P.

By such a construction method, the scraping jig 20 removes the deposits on the inner surface of the pipe P, and the wiping jig 30 erases the traces of the deposits left on the pipe inner surface, and is formed on the outer periphery of the cleaning jig 40. The high-speed air / water mixed flow flowing through the air flow gap S ₁₀ cleans the inner surface of the pipe P, and the suction / separation / recovery means 3 separates and recovers the cleaning water and deposits.

  At this time, the scraping member 22 of the scraping jig 20 is mounted in a plurality of rows along the axial direction of the pipe line P as described above, and is mounted with a predetermined interval in each row, Since the entire inner periphery of the pipe P can be processed by all the scraping members 22, the air flow generated by suction is not blocked by the scraping member 22, and the entire inner periphery of the pipe P is reliably scraped. Can be taken.

  Further, since the brush member 32 of the wiping jig 30 is spirally wound around the main body, when the inside of the pipe P is sucked by the suction / separation recovery means 3, the air flow in the pipe P and the mixed air are mixed with this. The washed water flows through the spiral ventilation path 34 formed between the brush members 32 to form a high-speed swirling flow, and pushes out deposits such as rust residue that have entered the brush member 32. For this reason, the situation where rust and the like accumulate in the brush member 32 can be suppressed. In addition, since the washing water flows as a high-speed swirl flow, compared to the case where the washing water flows in a straight line, a force having multi-directional components is applied to the deposits attached to the inner surface of the pipeline. In combination with the cleaning process of the cleaning jig 40, the inner surface of the pipe line can be more reliably cleaned.

  As described above, the cleaning device 1 according to the first embodiment can reliably clean the entire surface of the pipe line while the cable K is present in the pipe line P, and water has accumulated in the pipe line P. Even in such a situation, the inner surface of the pipe is cleaned by cleaning the inner surface of the pipe with a high-speed swirling flow of the wiping jig 30 and cleaning the inner surface of the pipe with a high-speed air-water mixed flow that flows around the outer periphery of the cleaning jig 40. It can be performed. Further, the cleaning device 1 can reliably remove these with the scraping jig 20 and the wiping jig 30 even if adhered matter, rust, or the like is firmly attached to the inner surface of the pipeline, and repair work performed thereafter. Accuracy can be improved.

  Next, a second embodiment of the cleaning device and the cleaning method of the present invention will be described. In addition, about 2nd Embodiment, only a different point from 1st Embodiment mentioned above is demonstrated, about the same aspect part as 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 8 (side view) and FIG. 9 (side view), the cleaning device 1 ′ of the second embodiment has a suction / separation / recovery means 3 attached to one end of the conduit P. The washing water introducing means 8 is attached to the end, and the attachment positions with respect to the pipes P in the first embodiment are arranged in reverse. Moreover, the cleaning jig inserted into the pipe line is constituted by an introduction jig 10, a scraping jig 20, and a wiping jig 30 from the front side in the pulling direction.

  As described above, when the inside of the pipe P is sucked by the suction / separation recovery means 3, the wiping jig 30 causes the air flow in the pipe P and the washing water mixed therewith to the ventilation path 34 between the brush members 32. The inner surface of the pipe is cleaned as a high-speed swirling flow. That is, the wiping jig 30 has a cleaning function in addition to the function of erasing the traces of the deposits scraped off by the scraping member 22 from the inner surface of the pipe line. For this reason, using the wiping jig 30 as means for cleaning the inner surface of the pipe line, the above-described cleaning jig 40 can be omitted. Thus, the cleaning jig inserted into the pipe line P in the second embodiment is constituted by the introduction jig 10, the scraping jig 20, and the wiping jig 30.

  In the cleaning method using the cleaning device 1 ′ thus configured, first, the scraping jig 20 and the wiping jig 30 are connected to the conduction jig 10 so that the conduction jig 10 is positioned on the front side in the pulling direction.
