The drain pipe 20 for draining the collected water to the outside, the first and second cable pipes are connected to both sides of the drainage treatment pipe 10, respectively, and the first and second high-voltage cables (1,2) are respectively routed therein. It consists of (30,40). The drainage treatment pipe 10 includes a tubular treatment tube body 11 for collecting water, first and second connection portions 12 and 13 respectively formed on the left and right sides of the treatment tube body 11 , and the treatment tube body 11 . ) is composed of a drain connection part 14 that guides the water collected in the drain pipe 20 to the drain pipe 20 . The treatment pipe body 11 has an oval shape whose central part is more convex than the left and right sides so that water penetrating into the first and second cable pipes 30 and 40 does not penetrate through the joint of the first and second high-voltage cables 1 and 2 . That is, since the central portion of the treatment tube body 11 is convex (concave when viewed from the water collecting side), a lot of water can be collected. The first and second connecting portions 12 and 13 are formed to extend in a tubular shape on both left and right sides of the treatment tube body 11 and have a structure in which a thread is formed on an outer circumferential surface. If the joints of the first and second high-voltage cables (1,2) are spaced apart from the bottom of the treatment pipe body 10, it will be possible to more reliably prevent the penetration of water. At least one support rib 15 for supporting the first and second high-voltage cables 1 and 2, respectively, is formed to protrude from the portion. The support rib 15 is formed in a curved shape so that the first and second high-voltage cables 1 and 2 are seated therein. Since the support rib 15 should not block the flow of water while supporting the first and second high-voltage cables 1 and 2 , one or more through-holes 16 are provided through which water flows to the drain connection part 14 . The drain connection part 14 has a tubular shape extending downward to communicate with the outside at the bottom of the central portion of the treatment tube body 11 , and guides the water collected in the treatment tube body 11 to the drain tube 20 . One side of the drain pipe 20 is connected to the drain connection part 14 to drain the water induced to the drain connection part 14 . The other side of the drain pipe 20 drains water in correspondence with the existing ground or river. The first and second cable protection pipes 30 and 40 are tubular in which a thread is formed on the outer circumferential surface of the ends connected to the first and second connectors 12 and 13 of the drainage treatment pipe 10, and the first and second high-voltage cables are formed therein. (1,2) are respectively wired. The first and second connection parts 12 and 13 and the first and second cable protection pipes 30 and 40 of the drainage treatment pipe 10 may be pipe-joined through couplers 31 and 41, respectively. The couplers 31 and 41 have a screw thread formed on the inner circumferential surface, so that the screw thread is connected to the first and second connecting parts 12 and 13 threads and the first and second cables.

That is, the first and second high-voltage cables 1 and 2 are spaced apart by a predetermined height from the bottom of the waste water treatment pipe 10 by the support ribs 15 . Therefore, even if there is water at the bottom of the waste water treatment pipe 10 , water does not penetrate into the joint of the first and second high-voltage cables 1 and 2 . On the other hand, when water penetrates and flows inside the first and second cable protection pipes 30 and 40 , the water collected in the drainage treatment pipe 10 is directed toward the drain connection part 14 . Since the bottom of the treatment pipe body 11 of the wastewater treatment pipe 10 is inclined downward toward the drain connection part 14 , the water collected in the wastewater treatment pipe 10 is naturally directed to the drain connection part 14 . When the water inside the first and second cable protection pipes 30 and 40 flows into the drainage treatment pipe 10, it meets the support rib 15, but the drainage is processed through the through hole 16 of the support rib 15. It may be collected in the pipe (10).

The bottom portion of the protective tube body 110 is inclined downward toward the drain hole 120 to induce smooth drainage. The first and second high-voltage cables (1,2) are separated from the bottom of the protective tube body (110) to prevent water that has penetrated into the protective tube body (110) from penetrating through the joint of the first and second high-voltage cables (1,2). It is preferable to be spaced apart, and for this, one or more support ribs 130 for supporting the first and second high-voltage cables 1 and 2 are formed at the bottom of the protective tube body 110 , respectively. The support rib 130 is formed in a curved shape so that the first and second high-voltage cables 1 and 2 do not move, and one or more through-holes 131 so that the water inside the protection tube body 110 flows to the water collecting receptacle 200 . ) is formed. The water collecting receiver 200 has a water collecting part 210 for collecting water that has passed through the drain hole 120 . The water collecting unit 210 has an open upper portion facing the drain hole 120 and has a narrower cross-sectional area toward the lower portion. The water collecting unit 210 may be fixed to the cable protection pipe 100 through various structures, for example, it is fixed through a fastening band 220 . The fastening band 220 is fixed while enclosing the cable protection tube 100 and the opposite ends are fastened through a plurality of fasteners. Since the fastening band 220 surrounds the cable protection tube 100 , the water collecting part 210 can be firmly fixed to the cable protection tube 100 . The water collecting part 210 is integrally formed with the fastening band 220 .

A drain connection part 230 is formed at the outlet side of the water collecting part 210 in order to guide the water collected in the water collecting part 210 to the drain pipe 300 . The operation of the water distribution high-voltage cable pipe joint water leak treatment device according to this embodiment is as follows. The first and second high voltage cables 1 and 2 are wired inside the cable protection pipe 100 and buried in the ground, and are not damaged by earth pressure or the like through the cable protection pipe 100 . The first and second high-voltage cables 1 and 2 are seated on the support rib 130 and spaced apart from the bottom of the cable protection pipe 100 . Groundwater penetrates into the cable protection pipe 100 and flows along the cable protection pipe 100. At this time, since the bottom of the cable protection pipe 100 is inclined downward toward the drain hole 120, the water inside the cable protection pipe 100 is It faces the drain hole 120 . The water passing through the drain hole 120 is collected in the water collecting part 210 of the water collecting tray 200 , and then discharged to the outside after passing through the drain connection part 230 and the drain pipe 300 .
