Description

  TECHNICAL FIELD The present invention relates to excavation earth / material transporting / unloading system and excavation sediment / material transporting / unloading method, and in particular, excavation earth / material transporting system and excavation sediment / material transporting between a tunnel and a shaft surface. Concerning the way out.

  In general, the method of carrying in and out of excavated earth and sand / materials / equipment for tunnel construction with shafts is roughly classified according to the tunnel construction method and the tunnel scale.

  In the tunnel construction method, taking the two most widely used construction methods in recent years, the mud pressure shield construction method is a crane and rail that carry all the excavated sediment and materials and equipment from the face of the tunnel tip to the shaft above the shaft. Etc. are necessary.

  In the case of the muddy water type shield method, the excavated sediment is automatically carried out by a pipeline, so only a segment for lining, a crane, a rail for carrying rails, sleepers, and other materials and equipment are required.

  However, when a mud treatment facility in a pit or shaft is provided, a facility for carrying excavated sediment from the treated place to the ground is required.

  The carrying-in / out method according to the tunnel scale is roughly as follows, for example, when classified by shield outer diameter by the mud pressure shield method.

  First, many tunnels called small cross sections have outer diameters of about 2 m to 4 m or less, tunnel distances are often 2 km or less, and shafts are often shallow.

  In this scale of tunnel loading / unloading method, excavated sediment is transported by battery locomotive and Zuritro, and segments and necessary equipment are also transported by battery locomotive and cart.

  In addition, from the bottom floor of the shaft to the top of the shaft, the excavated earth and sand is carried in and out using a portal crane and materials and equipment are directly carried in and out using a portal crane.

  Secondly, the tunnel is called a medium cross section, and the outer diameter is about 4 m to less than 7 m, and the distance of the tunnel is 2 km or less, but the shaft is relatively shallow to a large depth.

  The carrying-in / out method from the tunnel of this scale to the shaft part of the shaft corresponds to the method of the small cross section by increasing the capacity of the device.

  Thirdly, the tunnel is called a large section, and the outer diameter is more than 7m, and it is a muddy water type shield in Japan, but it has a track record of up to 14.14m. The larger the diameter, the larger the size.

The carrying-in / out method for this scale tunnel is basically the same as that for the middle section, but when the excavation is carried out with a large section exceeding 10 m and further deep excavation and long-distance excavation, the following unloading is performed.
A: The belt is carried out by a continuous belt conveyor in the tunnel, and the vertical shaft by a vertical belt conveyor or a bucket conveyor.
B: A battery locomotive with a large Zuritro that is automated in the tunnel, a vertical belt conveyor or a bucket conveyor or the like in a vertical shaft, and the Zuritro may be directly carried out by a crane.

  Of these two methods, the shield outer diameter is 10m or more and long-distance excavation means that a large volume of excavated earth and sand is transported. Is a vertical conveyor.

  In addition, segments, materials and equipment will be loaded and unloaded by hanging the shafts with cranes, placing them on battery locomotives and luggage carts.

  Furthermore, recently, shields having a scale of 16 m or more exceeding a shield outer diameter of 14 m as an extra large cross section are being implemented.

  At this scale, the volume of excavated earth and sand is about 2.5 to 3 times larger with a segment 1 ring at 16m outer diameter than the shield with 10m outer diameter, and the daily processing capacity is nearly 10,000 tons. It is assumed that

  Moreover, even if it is a segment, the weight of one piece will be nearly 20 tons, and a heavy article will be suspended and conveyed.

  Furthermore, the shaft is also deep, and it is necessary to load heavy objects frequently and efficiently.

  In addition, tunnels will also be excavated for long distances, requiring high-speed construction, and transporting excavated earth and sand and materials and equipment in the tunnel will also have a large capacity.

  The muddy water shield method is classified in the same way as the mud pressure shield method, except for the excavated sediment transport.

JP-A-5-346096

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIGS. 1-13 is a figure which shows the excavation earth and sand / equipment carrying in / out system concerning one embodiment of this invention.

  FIG. 1 is a diagram showing the excavation sediment / equipment carrying-in / out system according to the present embodiment, in which (A) is a side view of the excavated sediment / equipment carrying-in / out system when the cage of the rising tower is raised, FIGS. 2A and 2B are a side view and a front view when the cage of the ascending tower is moved laterally from the state of FIG. 1 to the descending tower.

  The excavated sediment / material / equipment loading / unloading system 10 includes a rising tower 12 and a descending tower 14.

  The ascending tower 12 is disposed in the shaft 20 from the shaft bottom floor 16 to the shaft ground portion 18.

  Similar to the rising tower 12, the descending tower 14 is disposed adjacent to the rising tower 12 in the shaft 20 from the shaft bottom floor 16 to the shaft ground portion 18.

  The ascending tower 12 has a number of vehicle carrying cages 22 stacked to match the depth of the shaft from the shaft bottom floor 16 to the shaft ground portion 18, and the cage 22 can be moved up and down in the ascending tower 12. I have to.

  Similarly, the descending tower 14 includes a number of vehicle transport cages 22 that are suitable for the depth of the shaft 20 from the shaft lower floor 16 to the shaft ground 18, and the cage 22 descends in the descending tower 14. It is movable.

  Further, a rising jack 24 as a lifting means is provided at the lower part of the rising tower 12, and the lowest rising tower cage 22 carrying the vehicle 26 from inside the tunnel is lifted by the height of one cage. All of the cages 22 in the tower 12 can be lifted by one cage.

  Since this rising jack 24 can secure a space of several meters between the bottom floor 16 of the shaft and the bottom surface of the shaft 20, for example, four places are installed directly below the lowermost cage 22, In addition, since the height of one cage 22 is high enough to allow a small vehicle to load and exit from a large vehicle, the effective stroke of the lifting jack 24 is also approximately the same as the height of one cage.

For this reason, as shown in FIG. 3, the rising jack 24 uses a multi-stage jack in two stages as necessary in order to secure a large effective stroke.

  When the ascending jack 24 is operated to raise the lowermost cage 22 to the height of one cage, the uppermost cage 22 of the ascending tower 12 is lifted to the shaft 18 as shown in FIG. It becomes.

  At this time, there is provided positioning means for positioning in the horizontal direction by engaging the upper and lower cages 22 in the vertical direction.

  As the positioning means, as shown in FIG. 4, the dowels 28 projected from the upper surfaces of the cages 22 are engaged with receiving holes 30 formed at positions corresponding to the lower surfaces of the cages 22. The lateral displacement of the cage 22 is prevented.

  The engagement between the dowels 28 and the receiving holes 30 is the same in the cage 22 in the descending tower 14 so as to prevent displacement in the lateral direction when descending.

  The ascending tower 12 and the descending tower 14 are provided with a plurality of guide columns 32 for guiding the ascending or descending of the cages 22, and the guide rollers 34 that contact the side surfaces of the guide columns 32 are provided on the cages 22. This also provides a guide when the cage 22 is raised or lowered, so that each cage 22 can be safely raised and lowered sequentially at a predetermined position.

  In addition to the dowels 28, the receiving holes 30 and the guide rollers, although not shown, each cage 22 can also be provided by providing a rail-shaped concave and convex cage guide on the side surface of the cage 22 and the guide pillar 32 at the corresponding position. Can be moved up and down at a predetermined position.

  Further, as shown in FIG. 5, each cage 22 is supported in a stopped state by a locking means 36 at a predetermined ascending position or descending position.

  The locking means 36 is a saddle type attached to the guide column 32 of the ascending tower 12 and the descending tower 14, and as shown in FIG. By projecting toward the cage 22 side from the side, the locked state is maintained at a predetermined position by engaging with the lock hole 40 on the cage 22 side, and as shown in FIG. The stop state is released by pulling it out of the box.

  Further, as shown in FIG. 6, the guide columns 32 of the ascending tower 12 and the descending tower 14 are provided with cage fall prevention means 42 for preventing the cages 22 from dropping. Sexuality is ensured.

  The fall prevention means 42 is configured such that the fall prevention lever 44 can be operated by a solenoid 46. On the rising tower 12 side, as shown in FIG. Thus, when the cage 22 is raised, the fall prevention lever 44 automatically retracts, and when the cage 22 passes, the automatic fall prevention lever 44 protrudes to prevent the fall.

  On the descending tower 14 side, as shown in FIG. 5B, when the cage 22 is lowered, the solenoid 46 is operated so that the fall prevention lever 44 is moved backward to be lowered, and when the cage 22 is lowered, the solenoid 46 is disconnected. By doing so, the fall prevention lever 44 automatically protrudes to prevent the fall.

  The lock means 36 and the cage drop prevention means 42 are provided for each cage 22 and are fixed to each cage 22 and prevented from dropping.

  Furthermore, as shown in FIGS. 7 to 9, the uppermost cage 22 of the rising tower 12 pushed up to the shaft ground portion 18 moves the mounted vehicle 26 from the cage 22 to the shaft ground portion 18 and then empties. The uppermost cage 22 of the rising tower 12 that has become the upper side moving means 48 is laterally moved onto the uppermost cage 22 of the descending tower 14 so that the vehicle 26 can be mounted in the cage 22 from the vertical shaft 18. ing.

  The upper lateral movement means 48 includes a cage floating jack 50, a roller conveyor 52, and an electric motor chain conveying device 54.

  The cage floating jack 50 is movably supported by the electric motor chain device 56 as shown in FIGS. 7 and 8, and is located at a position away from the jack receiving seat 58 at the four corners of the bottom of the cage 22 shown in FIG. As shown in FIG. 8 (A), the cage floating jack 50 is moved to a position below the jack receiving seat 58 by driving the electric motor chain conveying device 56, and as shown in FIG. 8 (B), The cage floating jack 50 is extended so that the cage 22 is floated from the ground by supporting four points.

  FIG. 9A shows a state in which the cage of the rising tower 12 is floated using the floating jack 50 in this way.

  As shown in FIG. 9A, the roller conveyor 52 is an electric jack link on the turntable 60 (see FIGS. 9C and 9D) between the ascending tower 12 and the descending tower 14. It is supported in a folded state by a mechanism 62 (see FIG. 9C).

  Then, as shown in FIG. 9A, with the cage floating jack 50 being used to lift the uppermost cage 22 of the rising tower 12, as shown in FIG. After the conveyor 52 is rotated 90 degrees and placed under the cage 22, the electric jack / link mechanism 62 is expanded as shown in FIG. 9C, and the roller conveyor 52 is parallel to a predetermined position under the cage 22. Open to position.

  As shown in FIGS. 9C and 9D, the electric motor chain conveying device 54 is disposed at the front and rear positions across the ascending tower 12 and the descending tower 14, and the cage 22 is held by the cage floating jack 50. After being lowered onto the roller conveyor, the electric motor chain conveying device 54 is driven to move the cage 22 from the rising tower 12 side to the descending tower 14 side.

  In this state, the cage 22 is lifted using the cage floating jack on the descending tower 14 side, and the roller conveyor 52 is returned to the original position using the electric jack / link mechanism 62 and the turntable 60. I am doing so.

  A lowering jack 64 as a lowering means is provided at the lower part of the lowering tower 14, and the lowering jack 64 supports the cage 22 directly above the lowermost stage at that position without the lowermost cage 22 of the lowering tower 14. The cage 22 immediately above the lowermost stage is lowered to the lowermost position, and the mounted vehicle 26 can be moved from the lowermost stage cage onto the vertical shaft.

  The descending jack 64 also descends the cage 22 by the height of one cage, so that the entire cage 22 in the descending tower 14 can be lowered by one cage.

The lowering jack 64 is also installed, for example, at four positions just below the cage 22 in the same manner as the rising jack 24. In order to secure a large effective stroke, two or more multi-stage jacks are used as necessary. It has become.

  When the descending jack 64 is operated to lower the cage 22 immediately above the lowest level to the height of one cage, the lowermost cage 22 of the descending tower 14 is placed on the vertical shaft 16 as shown in FIG. It will be lowered.

  As shown in FIG. 10, the cage 22 located at the lowermost stage of the descending tower 14 is laterally moved from the descending tower 14 to the ascending tower 12 by the lower lateral moving means 66, and the vehicle 26 on the shaft bottom floor 16 is moved to the ascending tower 12. It can be mounted on the lowermost cage 22.

  The lower lateral movement means 66 includes a roller conveyor 68 and an electric motor chain conveying device 70.

  Two roller conveyors 68 are arranged in advance along the moving direction on the vertical shaft 18, and the cage 22 is placed on the two roller conveyors 68.

  The electric motor chain conveying device 70 is disposed at the front and rear positions of the ascending tower 12 and the descending tower 14 of the shaft 18 and protrudes from the cage 22 to the conveying claws 74 attached to the conveying chain 72. The projecting portion 76 is engaged.

  Then, by driving the electric motor chain conveying device 70, the driving force is transmitted to the cage 22 via the conveying claws 74 and the projections 76, and the cage 22 rolls on the roller conveyor 68 to the rising tower 12. It has been moved.

  Next, a procedure for lateral movement of the cage using the lower lateral movement means 66 will be described with reference to FIG.

  First, as shown in FIG. 4A, the vehicle 26 is loaded into the empty cage 22 at the bottom of the rising tower 12.

  At this time, the cage 22 of the descending tower 14 remains in a state directly above the lowest stage.

Each cage 22 is provided with a vehicle stop 82 (see FIG. 4) so that safety is taken into consideration.

  Next, the operation cycle of the excavated earth and sand material / equipment loading / unloading system 10 will be described with reference to FIG.

  First, as shown in FIG. 2A, the vertical shaft 18 of the rising tower 12 has no cage 22 and is empty, and the vertical floor 16 of the descending tower 14 has no cage 22 and is empty. It has become.

  Next, as shown in FIG. 4B, the lowermost cage of the rising tower 12 is lifted by the rising jack 24 to raise the cage row, and the cage 22 immediately above the lowermost stage of the descending tower is lowered by the lowering jack 64. The cage row is lowered on the lower floor 16.

  Then, as shown in FIG. 3C, the uppermost cage 22 of the ascending tower 12 reaches the vertical shaft 18 and the lowermost cage 22 of the descending tower 14 reaches the lower shaft 16 of the vertical shaft.

  From this state, as shown in FIG. 4D, the vehicle 26 loaded with excavated earth and sand, for example, is discharged from the cage 22 in the shaft ground portion 18 of the ascending tower 12 and is on the shaft bottom floor 16 of the descending tower 14. For example, the vehicle 26 loaded with materials and equipment is taken out from the cage.
