The porous ceramic tube 30 has a plurality of electric wire accommodating holes 32 formed in a pottery cylinder 3 1 and through holes 3 3 for reverse connection bolts. At the same time, on the outer peripheral surface of the cylindrical body 31, there is provided a thickness reducing portion 34 for reducing the weight and engaging the transfer hook or the like. However, such conventional porous ceramic tubes 30 are heavy because they are made of pottery, and are easily damaged by impact, so there is a problem that they are not easy to handle. At the same time, due to the weight, it is necessary to shorten the length of one branch, and there is a problem that it takes time to construct. In addition, because there is a reduced thickness portion 34 on the 〆 surface, there is also a problem that it is not easy to roll when buried in the ground. [Problems to be Solved by the Invention] The present invention was developed to provide a wire-sharing ditch that can solve the aforementioned problems, is lightweight and easy to handle, can reduce construction time, and is easy to roll. [Method for solving the problem] The present invention developed to solve the above-mentioned problem is characterized in that the inside of a resin-made casing having a box-shaped external shape that can be divided into two is used to hold the resin-based paper standard. · National Standard (CNS) A4 specification (210J < 297mm) --- V-! --- 'outfit-- (please read the precautions on the back before filling in this page) Order the Ministry of Economic Affairs Central Standard Bureau S Industrial and consumer cooperatives print the A7 B7 ___ printed by the employee consumer cooperative of the Central Standards Bureau of the Ministry of Economics. V. Invention description (2) The tubular electric wire accommodating tube. Furthermore, the wire storage tube may be bifurcated into a T-shape, so that the branched end surface is opened in the side view of the casing as a branch line outlet, and at the same time, the wire storage tube may be bifurcated into a T-shape, dividing The end face of the fork and the side of the shell corresponding to the end face of the bifurcation are closed with a thin wall, but only break when using the bifurcation, and serve as a branch outlet. In addition, it may be used as a wire accommodating tube in which a bellows-shaped tube is connected to both sides of a hollow planar structure formed by a plane parallel to the housing on at least one side, and may also be parallel to the housing of the planar structure In parallel, a through-hole or thin-walled portion for branch extension is provided. [Embodiment] Hereinafter, an ideal embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a first embodiment of the present invention. 1 is a resin-made case, and 2 is two resin-made electric wire accommodating tubes installed inside the case 1. The housing 1 is preferably made of a resin having excellent impact resistance, and has a box-shaped external shape which can be divided into two from the center to the top and bottom. Although the outer surface of the case 1 is a smooth surface, a large number of reinforcing ribs 3 are provided at predetermined intervals inside. The parts other than the reinforcing ribs 3 inside the casing 1 become spaces, and the material is made of resin to make the whole lighter. The wire accommodating tube 2 is preferably made of flame-retardant resin, and has flanges integrally formed on both ends thereof. The length of the wire accommodating tube 2 is equal to the length of the housing 1. According to the figure, the wire accommodating tube 2 is held between the upper and lower housings 1, 1 and the reinforcing ribs 3 and 3, and the upper and lower sides are bolted 5 Yin 1, I fixed and assembled. At this time, the flanges 4 and 4 will be located on the shell 1,1. The size of the paper is not in accordance with the Chinese National Standard (CNS > A4 specifications (210j < 297mm) '_ · (Please read the notes on the back before filling in This page) • II J '-1 n I ml Bu · · i · ^ i I!-1 ^ 1 ml order ------ ^ 旅 --a two ends of 3. One more, although in the present invention There are 2 middle wire storage pipes, but it can also be made up of 3 or more. The wire sharing trench of the present invention constructed in this way is buried in the underground user like the previous porous ceramic pipe 30, but due to the whole system Made of resin, it is significantly lighter than the porous ceramic tube 30, and will improve impact resistance. Therefore, it will be easy to handle and can manufacture long-sized ones, so it will reduce the number of joints and improve workability. For the conventional porous ceramic tube 30, the reduced thickness portion 34 is provided on the outer surface. Since the product of the present invention can use the outer surface as a smooth surface, rolling in soil becomes easy, and there is also a case of overlapping placement. The stability is also excellent. In addition, because the wire sharing groove of the present invention is composed of the housing 1 and the wire housing tube 2 As a result, the most suitable resin can be used separately. Therefore, on the one hand, the housing 1 can be used as a person with excellent impact resistance to prevent damage during embedding as described above, and on the other hand, the wire storage tube 2 can also be used as a flame-retardant resin. To prevent spreading. Figure 2 is a diagram showing a second embodiment of the present invention. In the circle, the wire accommodating tube 2 is bifurcated into a T-shape, so that the end surface of the bifurcation is opened on the side of the housing 1 It is the outlet of the branch line 6. The previous porous ceramic tube 3 0 is difficult to process twice because it is made of pottery, and it is difficult to branch the branch line from the middle of the straight pipe, but when it is constructed as shown in FIG. 2, it will be easy to use The branch line is branched. And because the branch line outlet 6 can be used as a vertical plane, the connector for branch line extraction can be installed, and the waterproof performance of the wire accommodating tube 2 can also be maintained. Furthermore, the end surface and the branch can also be corresponded to The light on the side of the shell 1 of the end face is closed by a thin wall, but it is only broken when using a bifurcation. It is used as a feeder outlet. 3 shows the present Figure 3 of the third embodiment. The wire-receiving tube 2 is ideally made of flame-retardant resin, and the bellows-shaped tubes 8 and 8 are connected to both sides of the central planar structure portion 7. The central planar structure portion 7, It is a hollow structure composed of at least 4 planes including at least a vertical plane 9 and a horizontal plane 10, and is a cylindrical body with a square cross section in FIG. 1. The vertical plane 9 and the horizontal plane 10 in the plane structure 7 There are through-holes or thin-walled portions 11, 1 and 2 for drawing the branch line. In addition, although the above description is to pull the branch line in the horizontal direction and the vertical direction, it can also be drawn in an oblique direction. An inclined surface will be provided on the housing, and a plane parallel to the inclined surface of the housing will be formed on the plane structure portion 7, and a through hole or thin-walled portion 1 30 for branch extension will be provided on this surface. The 8 series supports the part of the contained electric wire. Since the contact with the electric wire will become a point contact, the friction resistance when the electric wire is drawn into the pipeline can be reduced, so the electric wire can be easily drawn in. At the same time, since the bellows-shaped tubes 8 and 8 can be expanded and contracted, when the size of the resin-made casing 1 changes according to temperature changes, it can also expand and contract with this to absorb the change in size. Both ends of the bellows-shaped pipes 8, 8 are provided with flanges 4, 4 to be fixed to the casing 1. In this way, the wire sharing groove of the third embodiment is composed of the two sides of the wire receiving tube 2 according to the bellows-shaped tubes 8 and 8. Therefore, the friction resistance when pulling the wire into the pipeline can be reduced When the size changes according to temperature changes, it can be absorbed.
