DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, a monorail system according to an embodiment of the present invention will be described.

As shown in FIGS. 1 to 4, the monorail system 100 is for installing a wind-induced slab in a tunnel in which wind-induced slabs are installed. Also, the monorail system 100 may be installed at the top of the tunnel T so as not to collide with other construction equipment when the tunnel is constructed. Particularly, in the embodiment of the present invention, the monorail system 100 is installed not only above the height of the piers D installed at a certain height in the tunnel T, but also on the lower part of the monorail system 100, The wind slab C can be installed so as to move at a position higher than the bridge pier D. [

Such a monorail system 100 may include the rails 1.

The rail 1 may be formed in the longitudinal direction of the tunnel T at the upper end of the tunnel T subjected to the lining operation. The rail 1 is a long steel material used as a traveling path of the monorail system 100 when the monorail system 100 is moved and used to reduce the running resistance.

The rail 1 may include an I beam whose cross section is formed in the shape of alphabet I with respect to the longitudinal direction of the tunnel T. [ More specifically, the rail 1 may be composed of a head, an abdomen, and a bottom with respect to a transverse section, and the head is connected to the upper horizontal portion of the rail 1 by a tunnel (T And the abdomen portion is a path through which the roller 12 is brought into contact with a slender vertical portion of the rail 1. The bottom portion is a horizontal lower portion of the rail 1 and a wheel 11 It is possible to travel along the upper surface of the bottom portion.

In the present invention, the rail 1 is applied as an I beam but may also be formed as an H beam. On the other hand, the shape of the rail 1 is not limited thereto, and may be formed in various shapes.

Meanwhile, the monorail system 100 of the present invention may include a support frame 10.

The support frame 10 may include a bracket formed perpendicularly to the extending direction of the rail 1. The bracket encloses the wheel 11 to be described later and serves to fix the wheel 11 to the upper portion of the support frame 10 so as to be rotatable.

This support frame 10 includes a wheel 11 disposed on the rail 1 and rotated along the rail 1 and can be moved forward or backward of the tunnel in accordance with the rotation of the wheel 11. [ At this time, the wheel 11 can be supported by the bracket described above.

Here, the wheel 11 may be configured to include a backward driving rubber coating roller and a direction inner front rubber coating roller. That is, the wheel 11 is seated on the upper surface of the bottom of the rail 1 and can travel on the upper surface.

This support frame 10 may optionally include rollers 12 that rotate along the side of the rail 1. That is, the roller 12 can be rotated in parallel with the rail 1 so that the support frame 10 can be moved on the rail 1 in the longitudinal direction of the tunnel. The rollers 12 can be moved along the abdominal side of the rails 1.

In more detail, the roller 12 is configured such that when the support frame 10 moves on the rail 1 while the wheel 11 is rotating, the support frame 10 can be safely moved in parallel with the rail 1 It is a role to help.

Meanwhile, the support frame 10 may include a horizontal frame 13 to which a support shaft 20 to be described later is coupled.

The horizontal frame 13 supports the support shaft 20 to be described later and serves to hang the upper frame 30 from the support frame 10 in a state of being horizontally perpendicular to the gravity direction. The brackets of the wheel 11 and the wheel 11 may be fixed above the horizontal frame 13.

In the horizontal frame 13, a seating portion 13a recessed in a hemispherical shape downward from the central upper surface of the horizontal frame 13 can be formed and a through hole (not shown) extending downward from the seating portion 13a 13b may be formed. At this time, the diameter of the through hole 13b is formed to be smaller than the diameter of the seating portion 13a.

Meanwhile, the monorail system 100 of the present invention may include a support shaft 20.

The support shaft 20 is fixedly coupled to the upper end of the upper frame 30. The support shaft 20 connects the support frame 10 and an upper frame 30 to be described later and is fixedly coupled to a central portion of the upper frame 30. The support shaft 20 is vertically upward .

A contact surface of the horizontal frame 13 with the seat portion 13a is formed in a hemispherical shape corresponding to the shape of the seat portion 13a and seated on the seat portion 13a at the upper end of the support shaft 20, Therefore, the head 21 which can be rotated within a certain range can be formed. The support shaft 20 may also include a shaft portion 22 extending downward from the head 21 and passing through the through hole 13b. At this time, the diameter of the shaft portion 22 is set such that the horizontal shaft 13 and the upper frame 30 can be separated from each other by a predetermined distance in a state where they are parallel to each other, The diameter of the through hole 13b is preferably smaller than the diameter of the through hole 13b.

Meanwhile, the monorail system 100 of the present invention may include an upper frame 30.

The upper frame 30 is formed in a plate shape and can be connected to the lower portion of the support frame 10 by a support shaft 20 connected to the center of the support frame 10 in a suspended state. Further, the upper frame 30 can be kept horizontal by the rotation of the support shaft 20. [ That is, even if the support frame 10 is in a state parallel to the rail 1 in the section where the rail 1 is not in the horizontal state, the head 21 of the support shaft 20 can not move horizontally, So as to maintain the horizontal position. That is, even if the seating portion 13a of the horizontal frame 13 rotates out of the horizontal state, the support shaft 20 is maintained in the gravity direction, and the upper frame 30 can also be maintained in a state perpendicular to the gravity.

The upper frame 30 may include a wire drum 31 disposed at a predetermined distance from the upper frame 30 with the support frame 10 therebetween.

The wire drum 31 refers to a moving body (cylindrical shape) that winds the wire W, and a wave-like groove may be continuously formed on the cylindrical surface to wind the wire W in order. The wire W can be wound or unwound by driving the wire drum 31. [

Meanwhile, the monorail system 100 of the present invention may include a lower frame 40.

The lower frame 40 is formed in a plate shape and can be connected to the lower frame 30 by the upper frame 30 and the wire W. [ In this regard, a pulley (not shown) may be installed on the lower frame 40 to hang the wire W and to change the direction or speed of the force or to increase the pulling force.

Meanwhile, the monorail system 100 of the present invention may include a rotating frame 50. The rotary frame 50 is formed in a plate shape and connected to a lower portion of the lower frame 40 so as to freely pivot within a range of a predetermined angle (for example, 90 degrees) by a connection shaft 60 Can be rotated relative to the lower frame (40). Further, the rotating frame can load the air-conditioned slab to be installed in the tunnel T downward.

The rotary frame 50 may include an internal gear 51 inserted in the center and having teeth formed on the inner peripheral surface thereof. The rotary frame 50 is connected to a motor 41 provided on the lower frame 40 and has a pinion gear (not shown) engaged with the internal gear 51 on the outer peripheral surface thereof. The internal gear 51 is engaged by rotating the internal gear 51 to rotate the internal gear 51. [ The rotary shaft 52 may be installed to be offset from the center of the lower frame 40 and the rotary frame 50 by a radius of the approximately internal gear so that the pinion gear formed on the outer peripheral surface of the rotary shaft is engaged with the internal gear.

Therefore, the rotary frame 50 can be rotated relative to the lower frame 40 by the rotation of the rotary shaft 52. [ Of course, the configuration in which the rotary frame 50 is rotated with respect to the lower frame 40 may be formed including configurations different from those exemplified above.

On the other hand, the first ring 53 may be fixed to the lower end of the rotary frame 50. In this regard, the second annulus 54 may be fixed to the upper end of the air- Therefore, the air-bearing slab C can be fixed to the lower portion of the rotary frame 50 by fixing the first ring 53 and the second ring 54 and fixing the fixing ring 55 thereto. Or the rotary frame 50 may be formed with a fixing pin fixed to the second ring 54 formed at the upper end of the air-bearing slab C in correspondence with the second ring 54. [

The lower frame 40, the rotating frame 50 and the wind direction slab C described above can be moved up and down within the tunnel T in accordance with the winding or unwinding of the wire W. [

Meanwhile, the lower frame 40 and the rotary frame 50 may include a connecting shaft 60. The connecting shaft 60 may pass through the lower frame 40 and the center of the rotating frame 50 to connect the lower frame 40 and the rotating frame 50. More specifically, the connecting shaft 60 may be mounted on the upper end of the lower frame 40, and the lower portion may be installed inside the rotating frame 50 through the lower frame 40.

Hereinafter, a monorail system control method performed by the monorail system 100 described above will be described.

The configuration of the monorail system to be described later has been described above, so that duplicated description will be omitted.

6 is a flowchart illustrating a method of controlling a monorail system according to an embodiment of the present invention.

The wire drum 31 provided at the upper end of the upper frame 30 is driven to pull out the wire W connected to the upper frame 30 and the lower frame 40 to lower the lower frame 40 (S11). At this time, the rotary frame 50 connected to the lower portion of the lower frame 40 is also moved downward.

The rotating frame 50 is rotated so that the longitudinal direction of the rotating frame 50 fixed to the lower portion of the lower frame 40 is aligned with the longitudinal direction of the tunnel T (S12). Of course, if the rotating frame 50 is already in such an arrangement state, the present arrangement state can be maintained.

Next, as shown in FIGS. 1 and 2, the wind tunnel slab C is loaded on the rotary frame 50 arranged in the longitudinal direction of the tunnel T in step S12 using the fixing pin 55 (S13).

3, when the air-conditioned slab C is loaded on the lower end of the rotary frame 50 in step S13, the rotary frame 50 is wound with the wire W and connected to the lower frame 40, The wind direction slab C loaded thereon is also moved upward. At this time, the lower frame 40, the rotating frame 50, and the wind-induced slab C move to a position higher than the position where the bridge pillar D is installed. Then, the lower frame 40 is moved to the upper side of the tunnel T (S14).

When the lower frame 40 is moved upward of the tunnel T in step S14, the monorail system 100 is moved to the target point of the tunnel T in which the wind direction slab C is installed (S15). The monorail system 100 is moved along the rail 1 to a specific position inside the tunnel T by driving the wheel 11 of the monorail system 100. [

Herein, the target point is a tunnel position where the wind direction slab C is to be installed in installing the wind direction slab C on the pier D installed along the tunnel T. [

When the monorail system 100 reaches the target point in step S15, the monorail system 100 rotates the rotating frame 50 so that the longitudinal direction of the rotating frame 50 coincides with the width direction of the tunnel (S16). The rotation of the rotary frame 50 can be performed by rotating the rotary shaft 52 to rotate the internal gear 51 formed on the rotary frame 50 by the rotation of the pinion gear formed on the outer periphery of the rotary shaft 52. [

Fig. 5 is a view showing that the wind direction slab is moved laterally with respect to the width direction of the tunnel by the rack pinion. 5, the monorail system 100 of the present invention can move the rotating frame 50 to the left and right by driving a chain and a rack pinion 42 connected to the motor 41 (S17). That is, by driving the rack pinion 42, the rotary frame 50 can be prevented from colliding with the inner side surfaces of the tunnel by moving the rotary frame 50 to the left and right, and can be exactly matched with the width direction of the tunnel.

4, the wire W is pulled out and the concrete segment C fixed by the fixing pin 55 is placed on the pier D installed in the tunnel T (S18). Therefore, in order to make the rotating frame 50 rotate and coincide with the width direction of the tunnel T in step S17, the rotating frame 50 may be mounted laterally or symmetrically with respect to the center line of the tunnel after turning or turning.

At this time, since the spacing between the bridge piers D disposed on both sides of the tunnel is narrower than the width direction of the wind slab C, both ends of the wind direction slab C in the longitudinal direction are respectively hooked on the bridge pier D, (C) is installed.

By repeating this process, the construction of the wind direction slab C in the tunnel T can be completed.

This air-conditioned slab divides the tunnel (T) up and down to reduce the cross-sectional area of the lower part of the tunnel (T) to smooth the flow of air, thereby amplifying the ventilation effect without a separate ventilation means.

Hereinafter, a tunnel construction method in which a wind slab is installed at a pier of a tunnel using a monorail system will be described.

7 is a flowchart illustrating a tunneling method for installing a wind-induced slab at a bridge pier using a monorail system according to an embodiment of the present invention.

First, the ground on which the tunnel is to be constructed is excavated in the tunnel extension direction by using an excavator (S21). Tunnel excavation methods include blasting excavation, crush excavation, excavation, and mechanical excavation. At this time, the mechanical excavation method is a method of excavating the tunnel by pushing a forced cylindrical excavator called SHIELD in the ground.

Subsequently, the excavated soil can be transported to the outside of the tunnel while the excavator is being pumped (step S22). The method of conveying the excavated soil may include a method of transporting the excavated soil after the transportation vehicle enters the tunnel, or a method of conveying the belt conveyor when the belt conveyor is installed in the tunnel.

Simultaneously with the operation in which the excavated soil is transported to the outside of the tunnel in step S22, concrete is laid and lining is performed in at least a part of the already excavated section (S23). At this time, the lining is to finish the excavation surface to protect the surface of the excavated section. At this time, GROUTING construction can be performed together to strengthen the ground.

In step S23, at least a section of the lined tunnel is provided with a rail whose cross section is formed in an alphabet I shape with reference to the longitudinal direction of the tunnel (S24). Alternatively, the rail may be installed at the same time as the lining process.

In step S23, a pier facing the widthwise direction is installed at a predetermined height of the inner wall of at least a section of the section of the lined tunnel (S25). At this time, the piers play the role of supporting the wind slab to be seated.

On the other hand, if a rail and a bridge are installed in at least a part of a section of the lined tunnel, the monorail system described above is installed on the rail (S26). Here, the monorail system has been described above, and a description thereof will be omitted.

When the monorail system is installed in the rail in step S26, the air-conditioned slab is moved to the section where the lining, bridge, and rail installation are completed using the monorail system (S27).

Thereafter, the wind direction slab moved in step S27 is installed on the installed bridge pier in step S25 (step S28).

In the tunneling method of installing the wind direction slab on the bridge pier using the monorail system, steps S21 to S28 may be performed in parallel.

In other words, the step of performing the excavation process (S21) using the excavator and the process (S22) of discharging the excavated soil are performed in parallel at the forefront of the tunnel with respect to the advancing direction of the tunnel. The rail / pier installation work S23 to S25 is performed, and at the same time, the installation period (S26 to S28) of installing the wind slab using the monorail system is simultaneously performed, thereby minimizing the construction period.

At this time, the monorail system, which is the equipment for installing the wind slab, moves to the upper part of the tunnel, so that the equipment for transferring the excavated soil and moving the equipment for the lining work is free.

In the meantime, the specific method of placing the air-bearing slab in the step S28 has been described with reference to FIG. 6, and a description thereof will be omitted.

Using the monorail system described above, the wind tunnel slab installed on the pier of the tunnel can be used by separating the monorail system after the tunnel is completed and recycling it at the time of later construction. That is, by installing a rail at the top of the excavated tunnel and simply installing a monorail system on the installed rail, the wind slab can be installed quickly and easily in the tunnel.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
