Pipe 100 according to an embodiment of the present invention is a protective tube 101, the inner tube 102 is formed therein the flow path 104 is inserted into the protective tube 101, the fluid flows, and the inner tube It is composed of a support (103) for fixing the (102) inside the protective tube (101).

The protective tube (101) inner tube (102) and the support (103) can be molded from metal, but it is preferable to mold using a synthetic resin material. Synthetic resin material has excellent workability compared to metal, can reduce material cost, and has excellent stiffness and warmth. The protective tube 101 is formed into a circular cross section so as to effectively withstand earth pressure and delamination from the outside when buried in the ground.

1 and 2, the inner tube 102 is inserted into the protective tube 101, and the support 103 is protruded radially from the outer surface of the inner tube 102. The inner side tube 12 inserted into the protective tube 101 is fixed by being fixed to the inner surface.

The inner tube 102 may be molded into a circular cross section, but preferably, the inner tube in the longitudinal direction is shaped to have an elliptical shape larger than the inner diameter in the lateral direction.

In particular, it is more preferable to shape the oval of the inner tube 102 to be in the form of a light-receiving narrow, that is, in the form of an egg.

In the case of sewage pipes, various foreign matters flow with the sewage, and various foreign matters flow with the sewage, and the sewage pipes are deposited inside the sewage pipes, so that the sewage flow is not smooth. Occurs.

As shown in FIG. 2, the inner tube 102 is formed in an elliptical shape such that the inner diameter in the longitudinal direction is larger than the inner diameter in the lateral direction, and more preferably in the form of an egg, so that various foreign substances flowing with the sewage are not deposited. Induced to be discharged with the sewage, that is, the various foreign matters flowing with the sewage is mostly greater than the specific gravity, so as shown in Figure 4 foreign matter sinks to the bottom of the inner tube 102, the pipe according to the present invention Since the inner tube 102 of the 100 has an egg-shaped cross-section, the flow rate of the fluid flowing under the inner tube 102 is fast, so that the inner tube 102 flows out with the fluid without being deposited.

The inner tube 102 inserted into the protective tube 101 protrudes radially. The inner tube 102 is fixed inside the protective tube 101 by the support 103 fixed to the inner surface of the arc tube 101.

The support 103 may be formed by protruding two supports 103 in the up and down direction of the inner tube 102, as shown in Figure 2, and the upper and lower of the inner tube 102, as shown in FIG. Four supports 103 may be formed to protrude in left and right directions, and more supports 103 may be formed.

However, since the support 103 is not a structure that is subjected to a large load, it is preferable not to exceed four. If more than four supports 103 are formed, the fluid flows through the inner tube 102 and the vibrations generated are transmitted to the protective tube 101 through the support 103 to the noise caused by the flow of the fluid Because it can be transmitted to the outside.

Therefore, as shown in Figure 2, the support 103 is most preferably constituted two in the up and down direction of the inner tube (102).

As described above, when the inner tube 102 is fixed inside the protective tube 101 using the support 103, a space 105 is formed between the inner tube 102 and the protective tube 101. 105 reduces the noise caused by the fluid flowing through the inner tube 102 to prevent transfer to the outside, and the fluid flowing through the inner tube 102 by the space portion 105 in the cold winter Prevent freezing.

Another embodiment of the present invention, as shown in Figure 6, the inner tube 102 is inserted into the inside of the protective tube 101, the inner tube 102 is longer than the inner diameter length in the longitudinal direction of the inner tube 102 The inner tube 102 is configured such that the longitudinal outer diameter is the same as the inner diameter of the protective tube 101 such that the inner tube 102 is in close contact with the inner wall of the protective tube 101. In another embodiment of the present invention configured as described above, since the space portion 105 is formed between the protective tube 101 and the inner tube 102, the fluid flowing through the inner tube 102 by the space portion 105 is formed. Since noise is not transmitted to the outside, and the fluid flowing through the inner tube 102 does not freeze even in the cold winter, the pipes are prevented from freezing, and even if the protective tube 101 is broken by earth pressure or strong external shock, To prevent leakage.

And preferably, as shown in FIGS. 5 and 6 by layering the filler 106 in the space portion 105 to prevent noise from being transmitted to the outside more effectively, the fluid flowing through the inner tube 102 。 Can prevent freezing.

The layered material 106 is layered with a known fiber material and various synthetic resins excellent in sound insulation and heat insulation for sound insulation and heat insulation.

And the outer surface of the protective tube 101 as shown in Figure 5 and 6 synthetic resin such as urethane By coating the coating layer 107 to form a coating layer 107 can more effectively block the transmission of noise to the outside, increase the thermal insulation, prevent the corrosion of the protective tube 101, and can be configured to complete the external lamination. .

Although not shown in the drawings, the inner tube 102 may be constructed by forming protrusions (not shown) on the surface of the protective tube 101 so as to coincide with the upper direction of the inner tube 102 so that the inner tube 102 can be constructed in the form of a light beam subsoil. When the inner tube (102) to be in the form of a light and down sine so that it can be installed easily and accurately without having to check each day.

Pipe 100 having a protective tube of the present invention configured as described above can reduce the noise caused by the fluid flow by preventing the noise caused by the fluid flowing inside the pipe to the outside, and various wastes with sewage In the case of sewage pipes flowing together, the sewage flows smoothly together with the sewage, rather than being deposited in the sewer pipes, thereby preventing the sedimentation from being seized on the sewer pipes and blocking the sewer pipes. Even if the protective tube is damaged by the protective tube or the protective tube is damaged by the strong stratification from the outside, the fluid flowing through the inner tube does not flow out.

In addition, because of the excellent heat retention by the space portion formed inside the pipe to prevent freezing of the fluid even in cold winter.

The piping according to the present invention has been described above.

It will be understood by those skilled in the art that the technical configuration of the present invention can be implemented in other specific forms without changing the technical spirit or essential features.

Therefore, the above-described embodiments are to be understood in all respects as illustrative and not restrictive, and the scope of the present invention is indicated by the appended claims rather than the foregoing description, and the meanings of the claims and All changes or modifications derived from the scope and equivalent concepts thereof should be construed as being included in the scope of the present invention.
