Description

CROSS-REFERENCE OF RELATED APPLICATIONS This application is the U.S. National Phase under 35 U.S.C. § 371 of International Patent Application No. PCT/KR2021/007139, filed on Jun. 8, 2021, which in turn claims the benefit of Korean Application No. 10-2020-0068947, filed on Jun. 8, 2020, the entire disclosures of which applications are incorporated by reference herein. TECHNICAL FIELD The present disclosure relates to a guide tube and a hyperloop device including the same. BACKGROUND ART In general, in a high-speed train system, capable of about 300 km/h or more, the issues of two types of resistance should be solved depending on the speed. One is to solve exponentially rising air resistance, and the other is to solve friction between a moving vehicle and a track. A technology introduced for this purpose is a Hyperloop device. Such a hyperloop device is a system for transferring a moving vehicle by magnetic levitation in a sealed tube at a pressure of about 0.001 atmosphere or less. In such a hyperloop device, while the electromagnetic and mechanical systems are important, it is important to implement a tube structure to maintain a sub-vacuum state of about 0.001 atmosphere or less, accounting for about 50% or more of an initial investment cost. In addition, a rail support member, a guideway installed in the tube, is required to maintain a straight line since it resists a load of a moving vehicle and guides the moving vehicle. That is, if the rail support member does not maintain a constant displacement tolerance (about 2 mm or less), a problem in which the moving vehicle deviates while driving, or the like, may occur. A factor directly affecting straightening of the rail support member includes deflection caused by a tube's own weight and the moving vehicle, and driving deflection caused by vibrations generated during driving of the moving vehicle. In order to control this, an installation position of the rail support member should be adjusted to compensate for deflection caused by the tube's own weight and deflection caused by the moving vehicle at the beginning, and rigidity of the tube should be sufficiently secured to resist vibration. Such a conventional method is configured to form a supporting point by making a through-hole in the tube to compensate for the initial deflection of the rail support member, connecting a bolt member to the through-hole, and then welding the same. A method of coupling the rail support member to the bolt member is used. However, this conventional method has a limitation in that it is necessary to form a through-hole in the tube, insert a bolt member thereinto, and then weld to fill a remaining portion of the through-hole. Such a drilling operation of the through-hole is costly and time-consuming, and in particular, there is a difficulty in forming the through-hole obliquely in the tube so that the through-hole is horizontal with the moving vehicle rather than in a circumferential direction of the tube. In addition, it is necessary to maintain a vacuum state inside the tube by performing infill welding after drilling the through hole, but there is a limit in that the vacuum of the tube cannot be secured depending on the reliability of this operation. Therefore, there is a need for research on a guide tube and a hyperloop device including the same to improve the above-described problems or limitations. SUMMARY OF INVENTION Technical Problem An aspect of the present disclosure is to provide a guide tube for facilitating installation of a rail support member and a hyperloop device including the same. Another aspect of the present disclosure is to provide a guide tube capable of improving a problem of deflection caused by an own weight of a tube main body member or vibration of a moving vehicle, and a hyperloop device including the same. Solution to Problem According to an aspect of the present disclosure, a guide tube, may include: a tube main body member; a rib member arranged in a longitudinal direction of the tube main body member, and coupled to an inner surface of the tube main body member; and a rail support member connected to the rib member.

The rib member of the guide tube according to an embodiment of the present disclosure may include a coupling tab portion formed to protrude in a direction of an inner surface of the tube main body member, provided in plural in a longitudinal direction of the tube main body member, and welded and coupled to the inner surface of the tube main body member. The rib member of the guide tube according to an embodiment of the present disclosure may include a friction damper portion having a slit hole, to which the rail support member is fitted and is connected to a portion of the slit hole, formed therein, so as to absorb vibration energy of the rail sup
