TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a method for laying a pipeline for transporting a gas or a liquid substance or a protection pipe for an electric cable (hereinafter, referred to as a “hollow pipe”) in a horizontal shaft tunnel continuous with a lower part of a shaft. In particular, when the shaft is deep and the horizontal tunnel is long, a method for safely loading a long hollow tube into the horizontal tunnel, and an efficient and low-cost method using the loading method. The present invention relates to a method for laying pipes in a tunnel.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when a hollow pipe is laid in a horizontal shaft tunnel substantially horizontally continuous from a lower part (near a bottom) of a substantially vertical shaft such as a common trench, a hollow tube shorter than the diameter of the shaft is used. Is generally horizontally lowered to the bottom of a shaft, and then each hollow tube is transported to a predetermined position in a horizontal shaft tunnel, and is sequentially connected by welding. However, in the method in which a new hollow pipe is always transported to the forefront of the completed pipe laid in this way, and is sequentially connected by welding and extended, the welding work site must also move sequentially to the back of the horizontal shaft tunnel. Therefore, when the horizontal tunnel becomes long, there is a problem in that the efficiency of the pipe laying operation is reduced.
[0003]
Therefore, in Japanese Patent No. 2754281 (Patent Document 1), a long tube manufacturing space is provided in a part of a horizontal shaft tunnel following a starting shaft, and a centering temporary assembling device and a welding machine installed in the long tube manufacturing space are provided. By using equipment, inspection equipment, and smoke exhaust equipment, a plurality of hollow pipes brought down from the starting shaft were welded and connected to form a long hollow pipe (unfinished pipe), and then the horizontal shaft was transferred by the transfer device. There has been proposed a piping method in a tunnel in which the inside of a tunnel is repeatedly moved and connected to a long pipe (completed pipe) that has been previously piped.

[Problems to be solved by the invention]
According to the piping method in the tunnel, the base end portion of the horizontal shaft tunnel connected to the starting shaft is used as a work space for manufacturing a long tube, and the hollow tubes descending from the starting shaft are sequentially elongated. Since pipes are laid, there is the advantage that welding fumes can be removed efficiently by consolidating in the long pipe production space area, and welding pipe work can be performed efficiently without deteriorating the work environment. The hollow pipe carried in from the pit has a length less than the maximum diameter of the pit (maximum horizontal cross section length) as before, and it was carried down in a horizontal state. The number of work could not be reduced.
[0006]
In order to reduce the number of welding operations, it is necessary to use a hollow pipe as long as possible.However, increasing the maximum diameter of the pit rather increases the cost of the entire construction. However, if the long hollow tube is to be dropped and carried vertically so as to be dropped into the shaft, if the hollow tube is horizontal at the bottom of the shaft and sent into the horizontal shaft tunnel again, Slinging work is required, which is complicated.
[0007]
Also, in the above-mentioned tunnel piping method, the welded hollow pipe (completed pipe) pushes the rear end located on the starting shaft side with a battery-driven transport device, or the front end located on the reaching shaft side. It is proposed to tow, but the work space tends to be insufficient because new hollow pipes are successively dropped in at the rear end side, and when towing the front end side, it is necessary to Cooperation with other operations such as a hollow tube loading operation and a welding connection operation becomes difficult, and there is a disadvantage that the safety of the operation is impaired.
[0008]
The present invention has been made in consideration of the difficulties of the conventional hollow pipe loading work and pipe laying work, and is intended to further reduce the number of man-hours and increase efficiency while improving the safety of a long hollow pipe horizontal tunnel. It is an object of the present invention to provide an internal loading method and a pipe laying method in a horizontal tunnel.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the method for carrying a long hollow tube into a horizontal shaft tunnel according to the present invention, a guide wire is stretched in a vertical direction on a side wall surface of a starting shaft facing a horizontal tunnel opening. On the other hand, a draw-in truck that can move from the vicinity of the lower end of the guide wire into the horizontal tunnel is provided, and upper and lower pipe suspenders are temporarily fixed to both ends of the long hollow pipe, respectively. With the hanging wire connected to the hanging tool, the long hollow tube is vertically lowered into the launch shaft, the upper pipe hanging tool is connected to the guide wire, and then the long hollow tube is further lowered to lower piping. The long hollow tube was placed horizontally by moving the hanging tool into the horizontal tunnel while being connected to the pulling cart. It was lowered along the guide wire while allowing it to adopt a longer hollow tube that was not constrained by the maximum diameter of the launch shaft by being suspended vertically into the launch shaft. Later, the pulling-in trolley made it easy to change direction in the horizontal direction.
[0010]
It is desirable that the drop-in truck is disposed on a temporary track laid from the bottom of the shaft to the inside of the horizontal tunnel, and is configured to be moved manually or electrically on the temporary track. In order to prevent falling accidents by lowering the long hollow tube in a stable state, temporarily suspend the upper and lower piping hanging members at both ends of the long hollow tube, and suspend them. The down wire is connected to the upper pipe hanger and the lower pipe hanger such that the down wire extends along the outside of the long hollow tube or is inserted through the inside of the long hollow tube. On the other hand, the connection between the guide wire and the upper pipe hanging tool may be loosely fitted with a snap hook or the like.
[0011]
In order to efficiently and sequentially lay the long hollow pipes carried down near the entrance of the horizontal tunnel in the horizontal tunnel as described above, the horizontal pipe tunnel laying method according to the present invention employs a horizontal horizontal pipe. A guide roller is temporarily provided on a frame provided at a plurality of locations at predetermined intervals in the tunnel, and a winch wire is provided from a temporary winch provided near the starting shaft as a turning point of the temporary pipe delivery fixed mount provided in the middle of the horizontal tunnel. A first step of connecting a plurality of long hollow pipes brought in from the starting pit, welding them, and then moving them to the pit side from the welding work place and temporarily placing them, and temporarily placing the unfinished pipes After being installed on the guide roller at a predetermined position of the frame and abutting against the last end of the completed pipe that has already been welded and connected and welded and connected, the completed pipe is connected to the reaching shaft using the winch wire. Only the second step of delivered was be performed in parallel.
[0012]
The frame provided in the horizontal tunnel is for distributing a plurality of pipes and holding them in a shelf shape, and is disposed at a plurality of locations at predetermined intervals so that the laid pipes do not bend. By temporarily arranging guide rollers at the positions where the hollow pipes are provided in this frame, completed pipes that have already been welded and connected or new unfinished pipes that are welded and connected to the last end of the completed pipes can be obtained. The work of sending in the direction of the reaching pit becomes easy. A sharp cap such as a conical shape may be temporarily attached to the foremost portion of each completed pipe to be sent out so as to be smoothly placed on the guide roller of the frame that reaches the next. .
[0013]
The winch wire is a temporary pipe disposed near the starting shaft with some space available by avoiding the narrow horizontal tunnel, with the temporary pipe delivery fixed mount provided in the middle of the horizontal tunnel as a turning point. A winding operation is performed by the winch. The location of the temporary pipe delivery fixed frame is located in the order from the entrance of the horizontal shaft tunnel to the reaching shaft, the welding work place for connecting a plurality of long hollow pipes in advance, and the welding connection of unfinished pipes. After the temporary storage site and the connection work site where a new unfinished pipe is welded to the end of the completed pipe, it is set in the completed pipe part that goes further in the shaft direction to the inside of the horizontal tunnel. For example, a winch wire is connected to the front end of the unfinished pipe transferred from the temporary storage site, and the front end of the unfinished pipe abuts on the tail end of the completed pipe already arranged at a predetermined position in the frame. By winding the winch wire stretched to the temporary winch provided at the bottom of the starting shaft at the turning point of the temporary piping delivery fixed base provided on the front side of the completed piping (close to the reaching shaft), and then welded. The completed pipes can be sequentially sent out together with the unfinished pipes for performing the work.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a portion from a shaft to a shaft tunnel, and shows a state in which a long hollow tube is being carried down into the shaft. FIG. 2 and FIG. 3 are schematic perspective views in which the vicinity of a drop truck provided at the bottom of the shaft in FIG. 1 is enlarged. These figures provide an overview of the undersea tunnel construction in which the horizontal tunnel B is connected horizontally to the lower part of the start shaft A excavated vertically from the ground surface, and the start shaft A has a depth of approximately It is assumed that an arrival shaft (not shown) similar to the starting shaft is constructed after passing through a horizontal shaft tunnel B having a diameter of about 12 m and a length of several hundreds of meters and having a length of 35 m. The method for carrying a long hollow pipe into a horizontal shaft tunnel according to the present invention is as long as possible in the horizontal shaft tunnel B when laying pipes of a plurality of lines in the horizontal shaft tunnel B represented by such an example. When it is possible to carry the hollow pipe 5 safely, and when laying work is to be carried out simultaneously from both of the two shafts, both shafts will be the starting shafts.
[0015]
As shown in FIG. 1, an upper temporary stage 1 is extended at the ground surface opening A2 of the starting shaft A, while the bottom A1 of the starting shaft A constructed one step lower than the opening of the horizontal shaft tunnel B is provided. A lower temporary stage 3 is installed in the upper and lower temporary stages 1 and 3. The lower temporary stage 3 is vertically spaced apart from the upper and lower temporary stages at regular intervals along the starting shaft wall A3 facing the opening of the horizontal shaft tunnel B. A guide wire 2 is stretched parallel to the direction. The upper temporary stage 1 is provided with a fence higher than the ground surface at a position near the center of the starting shaft A, and is devised to function as a fall prevention fence. The starting shaft A where the upper temporary stage 1 is not provided is provided. A fall prevention fence A22 is separately provided around the opening A2.
[0016]
In the vicinity of the lower end of the guide wire 2, there is provided a pull-in truck 4 which can be moved into the horizontal tunnel T. As shown in FIGS. 2 and 3, the drop truck 4 of this embodiment slides manually along two parallel temporary tracks 41 laid from near the lower end of the guidewire 2 into the horizontal tunnel T. Although it moves, a drive truck equipped with a power source such as a battery may be used. Two support columns 42, 42 are erected on the upper surface of the draw-in trolley, and a connecting member 44 is supported by a rotation shaft 43 spanned between the support columns 42, 42.
[0017]
Returning to FIG. 1, the long hollow pipe 5 is suspended and lowered into the starting shaft A by the crane CR. At the time of hanging down, the lower pipe hanging tool 51 is attached to one end of the long hollow pipe 5, and the upper pipe hanging tool 52 is attached to the other end of the long hollow pipe 5. . The lower pipe hanger 51 and the upper pipe hanger 52 are temporarily fixed to the long hollow pipe 5 using fixing bolts 521 or the like. In this example, the hanging wire CR1 from the crane CR is connected to the upper pipe hanger. Since the tip of the suspension wire CR1 is inserted through the through-hole 522 formed in the suspension tool 52 and is fixedly connected to the lower pipe suspension tool 51, it is suspended by the crane CR. Even when lowered, the long hollow tube 5 maintains the vertical state. For the connection and fixing of the tip of the hanging wire CR1 and the lower pipe hanging tool 51, a method of inserting a pin into the annular portion of the tip of the hanging wire CR1 is preferable for convenience of removal later.
[0018]
Further, in order to stably drop the long hollow tube 5, the upper pipe hanging tool 52 and the guide wire 2 are connected using a snap hook 523 or the like. Since the snap hook 523 is loosely fitted on the guide wire 2, the upper pipe hanging member 52, that is, the upper end of the long hollow tube 5 is elongated along the guide wire 2 without being separated from the guide wire 2. That is, the hollow tube 5 stably descends vertically.
[0019]
When the long hollow tubes 5 suspended and lowered one by one by the crane CR reach the bottom portion A1 (the lower temporary stage 3 in this example) of the starting shaft A, the connecting portion 511 extended from the lower pipe hanging tool 51. Is connected to the connecting member 44 of the pull-in truck 4 (see FIG. 2). After the connection of the two, the long hollow tube 5 is continuously lowered, and the pulling trolley 4 is moved in the direction of the horizontal tunnel B with the assistance of an operator if necessary.
[0020]
FIG. 3 shows a state in which the drop truck 4 is moved in the direction of the horizontal tunnel T from the state in which the lower pipe hanging tool 51 and the drop truck 4 shown in FIG. 2 are connected. As shown, the long hollow tube 5 gradually falls down to 5a-5b-5c as the pulling cart 4 moves. Also during this time, since the upper pipe hanging tool 52 is connected to the guide wire 2, the long hollow tube 5 is finally placed in parallel with the temporary tracks 41, 41 of the pull-in truck 4, that is, placed horizontally. Will be. The connection between the pulling trolley 4 and the lower pipe hanging tool 51 is released, and both the lower pipe hanging tool 51 and the upper pipe hanging tool 52 are removed from the long hollow pipe 5, and the hanging wire is inserted from inside the long hollow pipe 5. When the CR1 is pulled out, the work of dropping in the long hollow tube 5 is completed.
[0021]
The long hollow tube 5 placed in a horizontal state by the above-described operation is a roller conveyor (not shown) arranged in parallel on both sides of the temporary tracks 41, 41 of the draw-in cart 4, a horizontal tunnel. It will be transferred into the horizontal tunnel T by the hanger trolley arranged on the upper surface in B. Before the long hollow tube 5 is placed horizontally, as shown in FIG. 3, the draw-in cart 4 is used for the convenience of the rolling operation to be placed on the roller conveyor and the hanging operation by the hanger trolley. After passing, it is preferable that a suitable number of pipe receiving stands 45 be stretched so as to straddle the temporary tracks 41, 41. By setting the upper surface of the pipe receiving stand 45 to be the same height as the upper surface portion of the roller conveyor, the long hollow tube 5 placed on the pipe receiving stand 45 can be extremely easily placed on the roller conveyor. Can be moved.
[0022]
The long hollow pipes 5 carried into the horizontal tunnel T as described above are welded and connected in advance at a welding work place provided near the entrance of the horizontal tunnel B. FIG. 4 is a vertical cross-sectional view of a portion extending from the entrance of the horizontal tunnel T to the temporary storage site of the unfinished pipe via the welding work site, and the direction in which the left-side dropping truck 4 can be seen is the starting shaft A side. In the horizontal shaft tunnel B, frames L1 to L9 are provided at a plurality of locations at predetermined intervals in a cross-sectional direction. FIG. 5 is a front view showing an example of each of the frames L1 to L9 as viewed in the length direction of the horizontal shaft tunnel B. In the cross section of the horizontal horizontal shaft tunnel B, the left and right sides thereof are connected via the central portion passage B1. Are erected in multi-stage shelves, and piping is laid on each shelf.
[0023]
FIG. 5 shows a state in which guide rollers G are temporarily provided between each pipe and the shelf. As the guide roller G, a thread-wound shape in which two right and left flanges are erected in accordance with the width of the pipe at the roller portion is preferably used, and a substantially C-shaped clip is used to attach to each shelf of the frame L1 to L9. It is used by fastening and fixing.
[0024]
Now, returning to FIG. 4, in the horizontal tunnel T of this example, five frames from the first frame L1 to the fifth frame L5 starting from the starting shaft A side for securing each work place are temporarily provided. A part is removed, and a hanger trolley H is temporarily installed on the ceiling surface in the horizontal tunnel T from the third frame L3 to the fifth frame L5. The lower part of the hanger trolley H is secured as an efficient welding work place in which a turning roller TR is disposed at an appropriate position. In this welding work place, two long hollow pipes 5 which are brought down from the starting shaft A are introduced. The state in which they are welded and connected is shown. The number of long hollow tubes 5 to be welded and connected in advance in this way is not limited to two as in this example, and may be determined according to the length, the number of workers, and the like that can be secured as a welding work place.
[0025]
The long hollow pipes 5 welded and connected two by two are suspended by a hanger trolley H as unfinished pipes 50, and a temporary storage space is provided from the sixth frame L6 to the frame L9 located on the reaching shaft side, and each unfinished pipe is used as a temporary storage space. The completed piping 50 is temporarily placed at a shelf position where the piping is to be laid. At this time, a guide roller is temporarily provided on each shelf as shown in FIG. 5 in order to facilitate the delivery of the unfinished pipe 50 temporarily placed at each shelf position.
[0026]
The temporarily placed unfinished pipe 50 is sequentially sent out toward the pit, and is welded and connected to become a completed pipe 500. FIG. 6 is also a longitudinal sectional view of the horizontal shaft tunnel B, and shows the vicinity of the connection work place after the ninth frame L9, following FIG. Completed pipes 500 are laid in three stages in the vertical direction on the reaching shaft side on the left side in FIG. 6, and a temporary pipe is sent between the fifteenth frame L15 and the sixteenth frame L16 on which these completed pipes 500 are mounted. A fixed base 7 is provided. A winch wire 61 is stretched between the temporary pipe delivery fixed base 7 and a temporary winch 6 (see FIG. 1) provided near the lower end of the guide wire 2 in the starting shaft A at the turning point. The front end side of 61 is turned back to the start shaft A side again through the plurality of pulleys K2, K4 and the like in the temporary pipe delivery fixed base 7, and near the rear end of the completed pipe 500 (in the unfinished pipe 50 until immediately before welding connection). And a portion that is newly completed pipe 500). A connection point between the end of the winch wire 61 and the completed pipe 500 is shown as a point Y in FIG. In addition, the point X in FIG. 6 is a welding portion between the last end of the completed pipe 500 and the unfinished pipe 50 (however, the unfinished pipe 50 is a part of the completed pipe 500 due to this welding connection). .
[0027]
FIG. 7 is a schematic perspective view showing an arrangement state of a winch wire 61 connected from the temporary winch 6 to the unfinished pipe 50 via the temporary pipe delivery / fixing base 7. In the illustrated example, the load meter 62 is provided on the winch wire 61 between the temporary winch 6 and the temporary pipe sending / fixing pedestal 7, and the tip of the winch wire 61 is not connected via the four pulleys K1 to K4. The state where it is connected to the completed pipe 50 at the Y point is shown. Both the unfinished pipe 50 and the completed pipe 500 are mounted on guide rollers G temporarily provided on shelves of the frames L14, L15, L16. In the contact state, welding connection is performed at the point X. When the winch wire 61 is wound up by the temporary winch 6 after the welding connection, the completed pipe 500 and the unfinished pipe 50 are sent to the reaching shaft side.
[0028]
The above-described first step of temporarily moving the unfinished pipe 50 in which a plurality of the long hollow pipes 5 carried in from the start shaft A were welded and connected to the arrival shaft side from the welding work site, and temporarily placed. The unfinished pipe 50 is placed on a guide roller G at a predetermined position of the frame L, is brought into contact with the last end of the completed pipe 500, is welded and connected, and is then sent out to the reaching shaft using the winch wire 61. Since the process can be performed in parallel, if the parallel processing of the first process and the second process is a one-day operation, the work location is limited to the starting shaft A in the horizontal shaft tunnel. Work can proceed efficiently.
[0029]
【The invention's effect】
In the method for carrying a long hollow pipe into the horizontal shaft tunnel according to the present invention, the starting shaft is vertically suspended by hanging upright in the vertical shaft, so that the hollow shaft is not restricted by the maximum diameter of the shaft, and is not restricted by the maximum diameter of the shaft. Since it becomes possible to carry empty pipes, it is possible to reduce the man-hours for welding connection work to be performed later in the horizontal tunnel, thereby reducing the construction cost. In addition, since the long hollow tube is lowered along the guide wire, it does not come into contact with a structure such as a starting shaft, and by using a pulling bogie, the horizontal direction is continuously changed from the hanging down operation to the horizontal state. Since the conversion can be performed, the operation of sling the long hollow tube in the vertical state again is unnecessary, and the transfer can be performed extremely efficiently and safely into the horizontal tunnel.
[0030]
In the method for laying pipes in the horizontal shaft tunnel according to the present invention, the welding work place, the temporary storage place, and the connection work place are centrally located near the entrance in the horizontal shaft tunnel, so that the work efficiency is improved and utility, safety and environmental facilities are improved. Simplification can be achieved. In addition, the direction of pulling of the winch wire extending from the winch temporarily installed at the welding work site was changed by a temporary piping delivery fixed stand provided in the middle of the horizontal tunnel, and then connected to unfinished piping, etc. Communication and adjustment of the delivery operation can be performed reliably and quickly, which contributes to the safety operation, and the overall length of the winch wire can be kept short, which is economical.
[0031]
Further, since the guide rollers are provided on the shelf of the frame, the coefficient of friction at the time of sending out the completed piping or the like is reduced, and the winch is reduced in size, the winch wire is reduced in diameter, and the piping is prevented from buckling.
