That is, the buffer member 310, as shown in Figures 1, 2 and 4, is installed in the vertical direction on the vertical truss member and the inner wall of the side of the tunnel 10 and the vertical truss member 230 may be fixedly installed through the connecting means 313.

In this case, a second cloud means 315 may be mounted at the end of the hydraulic jack 311 at a portion where the inner side of the tunnel 10 contacts. Accordingly, when the truss structure 200 moves, the truss structure 200 may be moved without being worn or damaged by the inner side surface of the tunnel 10.

However, the second cloud means 315 may be applied without limitation in form and material as long as the truss structure 100 can be moved by cloud contact with the inner wall of the tunnel.

For example, preferably, the second cloud means 315 is provided with a magnetic layer 316 having permanent magnetism therein, as shown in the embodiment shown in FIG. 4, and has a magnetic force at the end of the hydraulic jack 311. It may be a steel ball attached by the rolling motion.

That is, the steel ball may be configured to coat the magnet layer 316 therein and to have a metal coating layer 317 on the surface thereof so that the surface of the steel ball has magnetic properties. Accordingly, the steel ball is attached to the end of the hydraulic jack 311 without a separate fixing means 330 can be rolling in various directions.

In addition, the end of the hydraulic jack 311 may be formed in the hemispherical groove corresponding to the shape of the steel ball to guide the rolling motion of the steel ball.

Accordingly, the steel ball can move in the vertical direction or the inclined direction as well as the longitudinal direction of the tunnel. Therefore, it is possible to cope with various obstacles and curvatures of the wall or the bottom surface of the tunnel.

Here, the hemispherical groove provided at the end of the hydraulic jack 311 and the surface of the steel ball may be provided with a wear preventing member to prevent the surface is worn by friction due to the rolling movement of the steel ball.

On the other hand, the connecting means 313 is provided with an elastic rubber having a fitting groove 314 is fitted to the hydraulic jack 311, the hydraulic jack 311 is spaced apart from the vertical truss member 230 by a predetermined interval.

That is, as shown in the embodiment shown in Figure 4, the connecting means 313 may be fixedly mounted to the vertical truss member 230 by fitting, etc., the fitting groove 314 provided in the connecting means 313 ), The end of the hydraulic jack 311 is fitted so that the connecting means 313 can be mounted on the vertical truss member 230.

In this case, the connecting means 313 may be rubber having an elastic force, and the fitting groove 314 is tapered in the direction of the vertical truss member 230 so that the end of the hydraulic jack 311 is the vertical truss member. It may be installed to be spaced apart a predetermined interval (t) without being in close contact with the 230. For example, the end of the hydraulic jack 311 may be fitted only about 60% to 70% of the fitting groove 314.

Accordingly, the connection means 313 may be flexibly elastically deformed due to the gap between the rubber material and the hydraulic jack 311 and the vertical truss member 230. Accordingly, the hydraulic jack 311 is deformed to form various angles with the vertical truss member 230 using the connecting means 313 as a contact point, for example, in the direction of the arrow shown in FIG. ) May be elastically supported with respect to the inner wall of the tunnel 10.

Accordingly, the shock absorbing member 310, the vibration jack due to contact with the tunnel 10 when moving the truss structure 200 not only by the hydraulic jack 311 but also by the connecting means 313 of the elastic material. The shock can be absorbed and cushioned.

On the other hand, the buffer member 310 is connected to the hydraulic jack 311 and the vertical truss member 230, the elastic support for elastically supporting the hydraulic jack 311 to provide a restoring force when the connection means 313 is deformed It may further include a support means (318).

That is, the elastic support means 318 is connected to the vertical truss member 230 and the hydraulic jack 311 around the connecting means 313, as shown in the embodiment shown in Figures 2 and 4, the hydraulic jack ( 311) may be elastically supported by the truss member.

At this time, the elastic support means 318 may be a spring having an elastic restoring force as shown in the embodiment, the spring may be coupled to about 2 to 4 to the one hydraulic jack 311. When the spring is provided with four, the hydraulic jack 311 can be stably supported because it is coupled to the top, bottom, left and right of the connecting means 313.

However, the material and the number of the elastic support means 318 is not limited to the case shown, various modifications are possible if the hydraulic jack 311 can be stably elastically supported.

Accordingly, when the connection angle of the hydraulic jack 311 is changed by the deformation of the connection member as described above, the hydraulic jack 311 is restored to the original position by the elastic support means 318 so that the shock absorbing member 310 ) Can stably support the truss structure 200.

On the other hand, the truss structure 200, as shown in the embodiment shown in Figs. 5 and 6, a plurality of unit truss 201 is constructed by connecting sequentially, any one of the neighboring unit truss 201 One end of the unit truss 201a may be assembled so as to overlap one end of the other unit truss 201b.

In addition, the truss structure 200 may further include a length adjusting unit 250 for adjusting the length of the truss structure 200 according to the length of the plurality of unit truss 201 overlap.

However, referring to the illustrated embodiment, the case where the length adjusting part 250 is provided only on the horizontal truss member 210 is illustrated, but is not limited thereto, and the length adjusting part 250 may be the vertical truss member. Also provided at 230 may adjust the length of the vertical truss member 230.

As the length of the tunnel truss structure 100 is configured to be adjusted as described above, even when the width of the tunnel 10 is variable, the work can be easily performed, and tunnels of various sizes using one truss structure 100 are provided. Maintenance work is possible. In addition, since the length can be adjusted in the longitudinal direction of the tunnel, the length of the repair can be shortened by stopping the truss structure 100 in the long case of the tunnel and increasing the length of the repair work in the stopped state.

At this time, the unit truss 201, as shown in the embodiment shown in Figure 6, the end of the unit truss 201a which is fitted to smoothly flow the load between the plurality of unit truss 201 is formed in a curve Can be.

Accordingly, in the general case in which the end of the steel pipe constituting the unit truss 201 is not curved, stress is concentrated at the end of the steel pipe at the connection portion of the neighboring unit truss 201 a, and thus the truss structure 200 is worn. Reusing) can prevent the problem of weakening the fitting force. That is, since the end portion of the unit truss 201a is formed in a curved line, the stress at the end portion of the unit truss 201 that is connected by moving the load capacity of the load in a streamlined form can be obtained.

On the other hand, the unit truss 201 is bolted through at least one of the plurality of length adjusting holes 203 and the length adjusting holes 203 formed to be spaced apart at predetermined intervals in the longitudinal direction and the plurality of overlapping It may be configured to include a fixing pin 204 for fixing the unit truss 201.

Accordingly, the neighboring unit truss 201 overlaps with each other so that the truss structure 200 has a required length, and one unit truss 201a and the other unit truss 201b are adjacent to each other. After adjusting the position of the length adjusting hole 203 of the) can be fixed by installing the fixing pin 204 to pass through the length adjusting hole 203.

5, a thread 204a is formed at both ends of the fixing pin 204, and the bolt 205 is formed at the fixing pins 204 at both ends of the unit truss 201 after the bolt is penetrated. Washer 206 may be fastened by screwing. Accordingly, the length of the truss structure 200 may be fixed.

However, the method of fixing the fixing pin 204 is not limited to the above-described method, and various modifications are possible if the fixing pin 204 can be fixed to the length adjusting hole 203.
