Description

  The present invention relates to a rail moving method capable of easily moving an existing rail including a branch portion.

  Conventionally, when exchanging a structure such as a railroad track, construction in a very short time within a limited time during which a train or the like does not travel is required. For example, when updating the rail, it is necessary to remove the existing rail and install a new rail in such a short time.

  As a method for updating such a structure, the traveling carriage is made to stand by on a rail that is installed in parallel, and the existing rail that has been removed is placed on the traveling carriage by a pretending device having a turntable, and the existing rail is retracted. At the same time, there is a bridge laying replacement method in which a new rail transported on parallel rails is installed at an installation site by the preemption device (Patent Document 1).

  In addition, although the rail is not relocated, a rail is installed on the bridge pier, and the endless track that moves by placing the bridge girder on the rail is used as a transfer stand, and the transfer stand is moved by a horizontal jack, and the bridge girder is moved sideways. There is a method (Patent Document 2).

Japanese Patent Laid-Open No. 11-1910 JP 2000-234111 A

  However, in the construction method as in Patent Document 1, there is a problem that even if the rail can be updated, the direction of the rail cannot be changed. For example, it is not possible to move an existing rail in the lateral direction or change the traveling direction of the rail.

  Moreover, in the method by patent document 2, although a bridge girder is moved to a horizontal direction, since the endless track connected to the jack runs on the H steel block, it can move only in the direction parallel to the H steel block. There is a problem. For example, there is a problem that a structure such as a bridge girder cannot be moved in an arbitrary direction such as an oblique direction with respect to the H steel block or a rotational movement around one point. Moreover, it is difficult to move the structure with high accuracy without simply deforming the structure by simply pushing the endless track with a plurality of jacks.

  FIG. 12 is a view showing a rail 61 having a branching portion 63. The rail 61 including the branching portion 63 is installed on the sleeper 65 and requires high accuracy. However, there are cases where it is necessary to relocate such rails 63 for installation of an elevated structure or the like. For example, as shown in FIG. 12, the rail indicated by the broken line is moved to the rail indicated by the solid line (in the direction of arrow H). In such a case, since the direction of the rail 63 is changed, the method as in Patent Document 1 cannot be used.

  Further, for example, when the rail 61 including the branching portion 63 is moved by a method such as Patent Literature 2, the rail 61 and the branching portion 65 cannot maintain accuracy due to deformation or the like. Therefore, instead of moving the rail, a temporary rail is installed at a position that does not hinder the operation of the railway with respect to the existing rail, and the permanent rail is used as shown in FIG. 12 while using the temporary rail. It is necessary to re-install in a proper position. Therefore, it takes a lot of labor to move the rails, and there is a problem that a wide construction area is required.

  The present invention has been made in view of such a problem. For example, even a rail that requires accuracy such as a branch structure can be quickly and accurately moved. It aims at providing the moving method of the rail which can move to the direction of.

In order to achieve the above-described object, the present invention is a method of moving a rail, the step (a) of providing a moving girder so as to be positioned at the lower part of the rail, and the rail on the side of the moving girder. A plurality of jacks are provided along the plurality of jacks , each of which can measure the amount of movement of the jack, and among the plurality of jacks, a jack positioned in the longitudinal direction of the moving girder is used as a reference jack, A step (b) of connecting a plurality of jacks other than the reference jack as a follow-up jack , connecting the jack and the moving girder, and setting a moving speed of the reference jack slower than the follow-up jack, Among the jacks, when the movement amount of one following jack exceeds a predetermined amount with respect to the movement amount of the reference jack, the movement of the one following jack is stopped,
A step (c) of resuming the movement of the one follow-up jack and moving the moving beam by the jack when the movement amount of the one follow-up jack is equal to or less than a predetermined amount with respect to the movement amount of the reference jack ; It is the moving method of the rail characterized by comprising.

  The moving girder has a plurality of steel-made vertical girders provided at predetermined intervals in a direction substantially parallel to the rail, and below the moving girder, a plurality of substantially parallel to the moving direction of the moving girder In the step (b), a jack is provided on the cross beam, and in the step (c), the cross beam is moved by moving the vertical beam on the cross beam. You may let them.

In the step (c), the moving direction of the moving girder by the jack may be a linear direction. In this case, the plurality of jacks can measure the moving amount of the jack by an encoder, In the step (b), among the plurality of jacks, a jack located substantially in the center in the longitudinal direction of the moving girder may be used as a reference jack, and a plurality of jacks other than the reference jack may be used as follow-up jacks .

Before the step (c), a rotating shaft is provided in a part of the moving beam, and in the step (c), the moving direction of the moving beam by the jack is the rotating direction around the rotating shaft. In this case, each of the plurality of jacks can measure the amount of movement of the jack by an encoder, and in the step (b), a jack provided at a part farthest from the rotating shaft is used as a reference jack. A plurality of jacks other than the reference jack may be used as follow-up jacks.

A rail having a branch structure may be provided on the moving girder.

A fluororesin plate and a stainless steel plate may be provided between the horizontal beam and the vertical beam, and in the step (c), the fluororesin plate and the stainless steel plate may slide.

According to the present invention, since a moving girder having a rail is provided above and the moving girder is moved by a jack, the rail can be moved in any direction depending on the moving direction of the moving girder. In this case, if the moving girder jack is used as a reference jack, the movement speed of the following jack is slightly faster than the reference jack, and the movement amount of the following jack becomes larger than the movement amount of the reference jack by a predetermined amount or more. Stop the following jack, and if the amount of movement of the following jack is less than the predetermined amount relative to the amount of movement of the reference jack, restart the movement of the following jack to control multiple jacks that move the moving girder with extremely high accuracy. The amount of movement of the moving digits can be managed with high accuracy. In particular, the moving digit has a vertical girder, and the vertical girder moves on a horizontal girder provided below the vertical girder, so that the movement is easy. Further, since the stainless steel plate and the fluororesin plate are provided, the frictional resistance becomes extremely small, and the movement of the moving beam is further facilitated.

  Further, if the moving direction of the moving beam is a linear direction, the moving beam can be moved in the jack installation direction. In this case, using the jack at the approximate center of the moving girder as the reference jack, the movement speed of the following jack is slightly faster than the reference jack, and the movement amount of the following jack is a predetermined amount or more with respect to the movement amount of the reference jack. When it becomes larger, the following jack is stopped. It is possible to control the movement amount of the moving digit with high accuracy.

  Further, by providing a rotation axis in a part of the movement beam, the movement beam can be moved in the rotation direction around the rotation axis. In this case, by using the jack farthest from the rotation axis as the reference jack, the movement amount of the moving digit can be managed with high accuracy as described above. Thus, the moving girder of the present invention can move the rail in any direction by combining the rotational movement and linear movement of the moving girder. Also, by combining rotational movement and linear movement, each movement moves in one direction, so the movement girder can be moved in each direction with concrete, etc., as in the case of complete movement in the free direction. It is not necessary to increase the rigidity and prevent the deformation completely. Therefore, even a moving body made of steel can obtain sufficient accuracy.

  The branching structure of the rail can be moved by accurately moving the moving girder. Therefore, since it is usually difficult to manage the accuracy, the branching section that could not be moved can be moved.

  According to the present invention, even a rail that requires accuracy such as a branch structure can be moved quickly and accurately, and the rail can move in any direction. Can be provided.

  Hereinafter, the rail moving method according to the embodiment of the present invention will be described. 1A and 1B are views showing an existing rail 1, in which FIG. 1A is a plan view and FIG. 1B is a cross-sectional view taken along line AA of FIG. 1A. In the following figures, each figure (b) shows a cross-sectional view of the corresponding figure (a) taken along the line AA in FIG.

  The rail 1 constitutes a branch part 3 and is installed on a sleeper 5. Further, as shown in FIG. 1B, the sleepers 5 are provided on the orbital crushed stone 11. The rail 1 is operated by the train in this state. In addition, illustration of the sleeper 5 is abbreviate | omitted in the rail 1 except the branch part 3 vicinity.

  In order to move the rail 1, first, as shown in FIG. 1, a ground 9 having a size equivalent to that of the rail 1 in the vicinity of the branch portion 3 is excavated to the side of the rail 1, thereby excavating the hole 7. Is provided. In addition, the earth retaining etc. which abbreviate | omitted illustration are provided in the circumference | surroundings inside the excavation hole 7. FIG.

  Next, as shown in FIG. 2, the underground beam 13 is installed in the excavation hole 7. The underground beam 13 is made of concrete, for example. A cross beam 15 is installed on the underground beam 13, and the horizontal beam 15 is fixed to the underground beam 13 with a bolt or the like. For the cross beam 15, for example, H steel can be used. The horizontal girder 15 is installed at a predetermined interval substantially parallel to the direction in which the moving girder described later moves. For example, if a moving girder described later is about 60 m long × 10 m wide, about eight horizontal beams 15 may be installed at intervals of about 5 m to 10 m. Actually, since the moving girder also rotates, the installation direction of the horizontal girder 15 does not have to be strictly parallel to the moving direction.

  FIG. 2C is an enlarged cross-sectional view taken along line BB in FIG. A fluororesin plate 17 is installed on the cross beam 15 over the longitudinal direction of the cross beam 15. The fluororesin plate 17 is joined to the cross beam 15 with a bolt or the like, for example.

  Next, as shown in FIG. 3, a vertical beam 19 is installed on the horizontal beam 15. A plurality of stringers 19 are installed, for example, in a direction substantially parallel to the rail 1. For the stringer 19, for example, H steel can be used. The vertical beam 19 is temporarily fixed to the horizontal beam 15 with a bolt or the like. The installation range of the vertical beam 19 is the size of the moving beam, which will be described later.

  FIG.3 (c) is the C section enlarged view of FIG.3 (b). A stainless steel plate 21 is installed below the stringer 19. The stainless steel plate 21 is joined to the stringer 19 by welding or the like. The stainless steel plate 21 does not need to be provided over the entire length of the stringer 19, and is provided, for example, so as to cover the vicinity of the intersection with the horizontal beam 15. Since the friction coefficient between the stainless steel plate 21 and the fluororesin plate 17 is extremely small, the stainless steel plate 21 can easily slide on the fluororesin plate 17. In the following drawings, illustration of the fluororesin plate and the stainless steel plate is omitted.

  Although not shown, the stringers 19 are made of steel plates provided on the stringers 19, or H steel provided in a position that is substantially perpendicular to the stringers 19 and does not interfere with the crossbeams 15. Are joined together. Accordingly, the plurality of stringers 19 are integrated. Since the integrated vertical beam 19 is temporarily fixed to the horizontal beam 15, it does not move in this state.

  Next, as shown in FIG. 4, the orbital crushed stone 29 is installed on the stringer 19 (on a steel plate not shown). Sleepers 27 and rails 23 are installed on the orbital crushed stone 29. The rail 23 constitutes a branching portion 25. In addition, the form of the installed rail 23 and the branch part 25 can be made the same as the existing rail 1 and the branch part 3, for example. The orbital crushed stone 29, the rail 23, etc. installed on the stringer 19 are integrated with the stringer 19. A movable girder 28 is constituted by the integrated vertical girder 19, orbital crushed stone 29, orbit 23, sleepers 27, and the like.

  A gravel stop for the orbital crushed stone 29 is provided around the moving beam 28. Further, when the moving girder 28 is constructed, the height of the moving girder 28 is determined so that the rail 1 and the rail 23 have the same height, and the moving girder 28 is constructed substantially horizontally. Further, the operation of the train or the like can be continued using the rail 1 until the construction of the moving girder 28 is completed.

  Next, as shown in FIG. 5, the rail 31 (dotted line in the figure) connected to the existing track is connected to the rail 23 on the moving girder 28. That is, a train or the like that has conventionally passed over the rail 1 (branch portion 3) travels on the rail 23 on the moving girder 28 instead of the rail 1. In addition, the said process is performed in the time slot | zone when there is no driving | running | working etc. of a night train. Therefore, it does not interfere with train operation. When the connection between the rail 31 and the rail 23 is completed, the operation of the train or the like can be resumed.

  After the rail 31 and the rail 23 are connected, the existing rail 1 and sleepers 5 are removed. After removal of the rail 1 etc., as shown in FIG. 5, the excavation hole 30 is provided in the site | part in which the rail 1 was installed so that the excavation hole 7 may be connected. After excavation of the excavation hole 30, the underground beam 32 is installed in the excavation hole 30. The underground beam 32 is integrated with the underground beam 13, and at this time, as shown in FIG. 5B, the underground beam 13 and the underground beam 32 are installed so that the upper surface height is the same. The

  Next, as shown in FIG. 6, a plurality of cross beams 37 are installed on the underground beam 32 in the extending direction of the existing cross beam 15. The horizontal beam 37 is connected to each horizontal beam 15. For the cross beam 37, for example, H steel can be used. The cross beam 37 is fixed to the underground beam 32 with a bolt or the like. Further, on the horizontal beam 37, similarly to the horizontal beam 15, a fluororesin plate 17 (not shown) is installed.

  A pin 33 and a hinge 35 are provided on one horizontal beam 37 of the plurality of horizontal beams 37 and in the vicinity of the intersection with the moving beam 28. FIG. 6A is a diagram showing an example in which a pin 33 and a hinge 35 are provided on a cross beam 37 below the drawing. Details of the pin 33 and the hinge 35 will be described later.

  Jacks 39 (39a, 39b, 39c, 39d, 39e, 39f, 39g) are provided at the ends of the cross beams 37 other than the horizontal beam 37 on which the pins 33 and the like are installed. A wire 41 is joined to each jack 39. The wires 41 are extended along the cross beams 37 on which the respective jacks 39 are installed, and are joined to the vicinity of portions of the vertical beams 19 that intersect with the cross beams 37. That is, each jack 39 is joined to the moving beam 28 via the wire 41.

  FIG. 7 is an enlarged view of the pin 33, the hinge 35, and the like. FIG. 7A is a plan view, and FIG. 7B is a front view. The pair of plate-shaped guides 34 is fixed on the cross beam 37 with bolts or the like. The pin 33 is held in a direction perpendicular to the cross beam 37 by a pair of guides 34. The pair of guides 34 are provided with holes into which the pins 33 can be inserted at corresponding positions, and the pins 33 can be inserted into and removed from the guides 34. A flange is provided above the pin 33, and the pin 33 does not fall out of the guide 34 in a state where the pin 33 is inserted into the guide 34 by information.

  The hinge 35 is a plate-like member and is fixed to the stringer 19 with a bolt or the like. The hinge 35 is provided with a hole through which the pin 33 can pass. The hinge 35 is inserted between the pair of guides 34, and the pin 33 is inserted so as to penetrate the pair of guides 34 and the hinge 35. The pin 33, the guide 34, and the hinge 35 may be made of steel, for example.

  The guide 34 fixed to the cross beam 37 and the hinge 35 fixed to the vertical beam 19 are rotatable about the pin 33 as a rotation axis. FIG. 7C is a diagram showing a state in which the vertical beam 19 is rotated around the pin 33 with respect to the horizontal beam 37.

  As described above, the cross beam 37 is fixed to the underground beam 32. Therefore, by releasing the temporary fixing of the vertical beam 19 from the horizontal beam 37 (horizontal beam 15) and applying a force to the vertical beam 19, the vertical beam 19 can be rotated around the pin 33.

  Next, as shown in FIG. 8, the entire moving girder 28 is rotationally moved. Before moving the moving girder 28, the vertical fixing of the vertical girder 19 and the horizontal girder 15 is removed in advance. As described above, the stringer 19 is rotatable about the pin 33 as a rotation axis. By operating the jack 39 connected to the moving beam 28 and pulling the moving beam 28 by a predetermined amount by the wire 41, the moving beam 28 can be rotationally moved (in the direction of arrow F in the figure). The details of the method for controlling the operation of each jack 39 when moving the moving beam 28 will be described later.

  Here, when the moving girder 28 is rotationally moved, the connection with the rail 31 connected in advance with the conventional track is cut off. Therefore, the moving process of the moving girder 28 needs to be performed at night when there is no train operation.

  FIG. 9 is a diagram showing a case where the moving beam 28 is further moved linearly. When the moving girder 28 is moved linearly, the pin 33 and the hinge 35 are removed, and the jack 39 (39h) is also installed on the horizontal girder 37 on which the pin 33 and the like are installed. Similarly to the other jacks 39, the jack 39 h is provided with a wire 41, and the wire 41 is joined to the moving girder 28.

  Next, by operating the jack 39 connected to the moving beam 28 and pulling the moving beam 28 by a predetermined amount by the wire 41, the moving beam 28 can be moved linearly (in the direction of arrow G in the figure). After the movement of the moving beam 28 is completed, the moving beam 28 (vertical beam 19) is fixed to the horizontal beam 15 (37) with a bolt or the like. Through the above steps, the moving girder 28 can be rotated and linearly moved.

  When the movement amount of the jack 39 is smaller than the movement amount of the movement digit 28, the movement digit 28 may be moved in a plurality of times. Further, the movement of the moving girder 28 may be only rotational movement or only linear movement, or may be rotated after linear movement.

  In addition, when the moving girder 28 is linearly moved, as in the case of the rotational movement, the rail 31 connected to the conventional track is in a disconnected state. Therefore, after the movement of the moving girder 28 is completed, the operation of the train or the like can be resumed by reconnecting the rail 31 connected to the track on which the train travels to the position of the rail 23 after the movement. When the moving beam 28 is moved, the fluororesin plate 17 provided on the horizontal beam 15 (37) and the stainless steel plate 21 provided below the vertical beam 19 slide. In this case, since the friction coefficient of both is small, the vertical beam 19 can be easily moved on the horizontal beam 15 (37).

  Next, a description will be given of a method for controlling each jack when moving the moving girder 28. FIG. 10 is a flowchart showing a method for controlling the jack 39.

  In controlling the jack 39, first, it is necessary to set a reference jack. A reference | standard jack is a jack used as the reference | standard for controlling a moving speed (movement amount) in the whole jack. When the moving girder 28 is rotated, the jack farthest from the center of rotation becomes the reference jack. That is, in FIG. 8, the jack 39a is the reference jack.

  Further, when the moving girder 28 is moved linearly, a jack (jack positioned at the approximate center of the jacks 39 arranged in parallel at a predetermined interval) connected to the approximate center in the longitudinal direction of the moving girder 28 is a reference jack. It becomes. That is, in FIG. 9, the jack 39d (or jack 39e) is the reference jack.

  All jacks other than the reference jack are tracking jacks. The operation of each of the following jacks is controlled only by the relationship with the reference jack, and the operation is not controlled between the following jacks. Therefore, the reference jack performs a certain operation under the set conditions, and the follow-up jack monitors the operation of the reference jack and is controlled in relation to the operation of the reference jack.

  When the reference jack is selected, first, the moving speed of the reference jack is set (step 101). The moving speed of the reference jack is a moving speed for moving the moving beam 28. When the moving girder 28 is rotationally moved, the rotational peripheral speed at the reference jack mounting position is naturally the moving speed of the reference jack.

  Next, the moving speed of the following jack is set (step 102). The moving speed of the following jack is set slightly faster than the moving speed of the reference jack. For example, it is set about 17% faster than the moving speed of the reference jack.

  Next, all of the reference jack and the follower jack are simultaneously started (moved) (step 103). That is, the movement of the movement beam 28 is started in accordance with the movement of the jack 39. An encoder is attached to each of the reference jack and the follower jack. Therefore, the amount of movement of each jack is grasped by the encoder.

  When the movement amount of the reference jack reaches the set movement amount (step 104), the movement of all the jacks is stopped and the movement is finished (step 109). That is, the moving digit 28 ends the set amount of movement.

  Until the movement of the movement beam 28 is completed, the movement amount of each follower jack is always compared with the movement amount of the reference jack. For example, the amount of movement of a certain following jack is compared with the amount of movement of the reference jack, and if the amount of movement of the following jack is larger than the amount of movement of the reference jack, the movement of the following jack is temporarily stopped (steps 105 and 106).

  As described above, the movement speed of the follower jack is higher than that of the reference jack. Therefore, when both are operated for the same time, the movement amount of the follower jack exceeds the movement amount of the reference jack. For example, when the movement amount of a certain following jack becomes 0.1 mm or more larger than the movement amount of the reference jack, the movement of the following jack is temporarily stopped. If the movement amount of the following jack is within a predetermined amount with respect to the movement amount of the reference jack, the following jack continues to move as it is.

  Even when a tracking jack is temporarily stopped, the movement amounts of the tracking jack and the reference jack are always compared. In a state where the following jack is temporarily stopped, when the movement of the reference jack proceeds and the movement amount of the reference jack becomes larger than the movement amount of the following jack by a predetermined amount or more, the following jack resumes the movement (step 107). 108).

  For example, when the movement amount of a follow-up jack in a certain pause state is 0.1 mm or more smaller than the movement amount of a reference jack (that is, the movement amount of the reference jack is 0.1 mm or more of the movement amount of the follow-up jack) In the case of overtaking), the movement of the following jack can be resumed.

  Note that the movement amount control of the following jack is performed individually for each following jack. Therefore, even if a certain follow-up jack is in a temporarily stopped state, other follow-up jacks may continue to operate, and all the follow-up jacks may be in an activated / stopped state at a time.

  FIG. 11 is a diagram showing changes in the movement amounts of the reference jack and the follower jack accompanying the control of the follower jack described above. The reference jack starts moving at a constant moving speed from the start of movement (point S) (step 103), and stops moving when the jack movement amount set value 49 is reached (steps 104 and 109). That is, the reference jack movement amount 43 increases linearly from the S point, and becomes constant when the jack movement amount setting value 49 is reached.

  A follow-up jack deviation upper limit value 47 and a follow-up jack deviation lower limit value 45 are set above and below the reference jack move amount 43 with a predetermined interval in the direction of the jack move amount. For example, the deviation of the reference jack movement 43 by U upward is the follow-up jack deviation upper limit 47, and the deviation of the reference jack movement 43 by L downward is the follow-up jack deviation. The lower limit is 45.

  The follow-up jack starts moving from point S simultaneously with the reference jack (step 103). Since the movement speed of the follower jack is larger than the movement speed of the reference jack, the gradient of the follower jack movement amount 51 is larger than the reference jack movement amount 43.

  When the reference jack and the follower jack continue to move, and the follower jack movement amount 51 reaches the follower jack deviation upper limit value 47 (point P), that is, when the follower jack move amount becomes larger than the reference jack move amount by U, The following jack stops moving (steps 105 and 106).

  Even if the following jack stops moving, the reference jack continues moving at a constant speed. When the follow-up jack movement amount 51 reaches the follow-up jack deviation lower limit 45 (Q point), that is, when the follow-up jack move amount becomes smaller than the reference jack move amount by L, the follow-up jack resumes the movement (step 107, 108).

  Thereafter, the following jack repeats the same operation, and when the reference jack reaches the jack movement amount setting value 49, the movement is stopped together with the reference jack (step 109). The operation is thus completed.

  As described above, according to the rail moving method according to the present invention, the rail can be moved in any direction by combining rotational movement and linear movement. In particular, by providing a rotating shaft such as the pin 33 in a part of the moving beam 28, the moving beam 28 can be rotated around the rotating shaft.

  When the moving girder 28 is moved, the fluororesin plate 17 on the horizontal girder 15 and the stainless steel plate 21 below the vertical girder 19 slide and the friction coefficient is small, so that the moving girder 28 can be easily moved. Can do.

  The movement of the rails can be completed in a short period of time because the moving girder 28 may be moved linearly or rotationally by a plurality of jacks. That is, the operation of the train or the like is not hindered except during the movement of the rail and while the track on which the train or the like travels is connected to the rail after the movement. For this reason, a rail can be moved at night when a train does not operate.

  Moreover, the moving girder 28 is used for the movement of the rail, and the moving girder 28 is linearly moved and rotated by a plurality of jacks. In each movement, the moving girder 28 moves in one direction. Compared with the case of completely free movement, the moving girder 28 does not need a large rigidity, and therefore, the moving girder 28 can have a steel structure, and the construction is easy.

  In addition, when the moving girder 28 is moved, one reference jack is determined from a plurality of jacks, and the movement amount of the other following jacks is controlled from the movement amount of the reference jack, thereby obtaining extremely high movement amount accuracy. For example, the moving digit can be moved within an error range of about several mm. Therefore, even a rail including a branch portion can be easily moved.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, if a guide roller or the like is provided along the moving direction of the moving beam 28 when the moving beam 28 is moved, the moving beam 28 can be moved straight along the guide roller. Moreover, as a construction method of the moving girder 28, the excavation hole 7 is provided on the side of the existing rail and the rail 23 is newly installed. However, a working space for the girder is secured on the side of the rail, and the existing rail If a lower part of 1 is excavated directly from the side and construction of underground beams and cross girders can be performed, a predetermined range including the existing branch part 3 can be constructed as a direct moving girder. In this case, the rail can be moved even in a narrow place where there is no site equal to the width of the track on the side of the rail and there is almost no space. Further, when the moving girder 28 is rotationally moved, the pin 33 is provided at the end of the moving girder 28. However, the installation site of the pin 33 or the like serving as the rotation axis may be an arbitrary part of the moving girder 28. it can.
