Description

  The present invention relates to an underground structure.

  Patent Document 1 discloses an underground structure built using a plurality of tunnels arranged side by side. After constructing multiple tunnels, this underground structure is constructed by removing the unnecessary lining of each tunnel to form a large space, and using the remaining lining of each tunnel, It is built by forming side walls and the like. The plurality of tunnels are sequentially constructed with a time difference, and the subsequent tunnel is constructed next to the preceding tunnel. Each tunnel is constructed by a propulsion method or a shield method.

  Here, the propulsion method is a method of constructing a tunnel by press-fitting a cylindrical propelling box, which is a tunnel lining, into the ground sequentially from a wellhead. In addition, a blade edge, an excavation machine, etc. are attached to the front-end | tip of a propulsion box. The propulsion method excavator may be one that digs itself by taking a reaction force on the propulsion box (that is, one that is equipped with a propulsion jack), or the thrust of the main jack transmitted through the propulsion box You may dig by. On the other hand, the shield method is a method of excavating a natural ground with an excavator installed at a tunnel face and assembling a segment to be a tunnel lining inside the excavator to construct a tunnel. In addition, a shield machine makes itself a reaction force against the segment assembled inside.

  By the way, in the underground structure of patent document 1, the guide groove is formed along the tunnel axis direction in the lining of one of the two adjacent tunnels (that is, the segment and the propelling box). In the lining of the other tunnel, a ridge that is slidably fitted into the guide groove of the one lining is formed. In this way, it becomes possible to construct the tunnel lining of the succeeding tunnel using the preceding tunnel lining as a guide, so that it becomes difficult for the adjacent tunnels to shift, and as a result, efficiently. It becomes possible to construct.

JP 2001-214699 A (paragraph 0022, FIG. 1)

  However, in this underground structure, since the ridge of the other tunnel just fits into the guide groove of one tunnel, the preceding tunnel (propulsion box etc.) meanders, or If it is twisted, the guide grooves and the ridges compete when pushing out the subsequent propulsion box, and as a result, the subsequent propulsion box may not be pushed out smoothly. Even if the preceding tunnel is constructed with a predetermined alignment, if rolling or pitching or the like occurs in the following tunnel excavator, the guide groove is still pushed when pushing the succeeding propelling box. There is a risk that the ridges compete with each other and the subsequent propelling box cannot be pushed out smoothly.

  In this way, in this underground structure, it is difficult to construct the following tunnel when the previously constructed tunnel is meandering or when rolling or pitching occurs in the following tunnel excavator. There is a risk.

  From this point of view, the present invention is an underground structure constructed by using a plurality of tunnels arranged side by side, and when the tunnel constructed in advance is meandering or the tunnel of the succeeding tunnel is advanced. It is an object of the present invention to provide an underground structure capable of smoothly building a succeeding tunnel even when rolling, pitching, or the like occurs in the machine.

The present invention devised to solve such a problem is an underground structure constructed by using a plurality of tunnels arranged side by side, and one of the two adjacent tunnels. In the lining, a guide groove that opens to the other tunnel side is formed along the tunnel axis direction, and in the lining of the other tunnel, a protrusion that loosely fits in the guide groove of the one tunnel. The ridge has a flange and a web rising from the flange, and the flange is joined to an inner peripheral surface of a lining of the other tunnel, It protrudes to the outside of the lining through a gap provided in the lining of the other tunnel .

  If a structure in which the guide groove of one tunnel and the protrusions of the other tunnel are loosely fitted is adopted like this underground structure, the tunnel constructed in advance will meander or twist, Even when rolling or pitching occurs in the tunnel excavator of this tunnel, these effects will be absorbed by the connecting part of both tunnels, so it is possible to construct the succeeding tunnel smoothly Become.

  In this underground structure, the protruding end portion of the protrusion of the other tunnel may be formed to have a width dimension larger than the opening width of the guide groove of the one tunnel. If it does in this way, it will become possible to prevent that the adjacent tunnel leaves | separates more than necessary, and it becomes possible to build an underground structure with high dimensional accuracy by extension.

  When a structure such as an underground structure according to the present invention is provided, when the tunnel is constructed in a meandering manner or when it is constructed, rolling or pitching is performed on the tunnel excavator of the succeeding tunnel. Even if such a situation occurs, it is possible to construct a succeeding tunnel smoothly.

First, a reference form for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  Subsequently, as shown in FIG. 2 (b), a fourth tunnel T14 is constructed next to the first tunnel T11 in the vertical direction (above), and the fifth tunnel T14 is positioned at a position adjacent to the tunnel T12 and the tunnel T14. A tunnel T15 is constructed, and a sixth tunnel T16 is constructed at a position adjacent to the tunnel T13 and the tunnel T14. The construction order of the tunnels T11 to T16 is not limited to that shown in the figure, and may be changed as appropriate. In the present embodiment, adjacent tunnels T1 and T1 are connected to each other via a joint J1 when the subsequent tunnel T1 is constructed. Further, water stop injection is appropriately performed on the joint portion A of the adjacent tunnels T1 and T1.

  The tunnel T1 can be constructed by the propulsion method or shield method, but in this embodiment, it is constructed by the propulsion method. That is, in this embodiment, the lining L1 of each tunnel T1 is composed of a plurality of propulsion boxes 10, 10,... (See FIG. 3) arranged in the tunnel axis direction, and the subsequent tunnel T1. Is constructed by sequentially extruding a plurality of propelling boxes 10, 10,... Along a preceding tunnel T1 next to the tunnel T1 constructed in advance. During construction of the tunnel T1, a lubricant is poured and filled around the propelling box 10, and after the construction of the tunnel T1 is completed, it is replaced with a curable backing material. In addition, although not shown in the drawings, in each tunnel T1, the propelling boxes 10 and 10 adjacent to each other in the tunnel axis direction are connected using bolts, nuts, and the like.

  Note that the excavator K shown in FIG. 2A is equipped with a propulsion jack (not shown) that digs itself by taking a reaction force on the propulsion box 10 (see FIG. 3) behind it. May be used, or may be excavated by the thrust of an unillustrated main jack transmitted from the wellhead side through the propelling box 10. Moreover, as a cutter head of the excavation machine K, what is equipped with the cutter spokes K1, K1 arranged radially, for example, and corner cutters K2, K2,. The cutter spoke K1 is configured to be extendable and contractable in the radial direction. Thereby, the excavation cross section can be made rectangular. The shape of the cutter head is not limited to the one shown in the figure, and may be changed according to the shape of the excavation cross section, soil quality, and the like. For example, although not shown, a cutter head including two oscillating cutters having a substantially diamond shape may be employed. In this case, the oscillating cutters are controlled in opposite directions so as to oscillate about the oscillating shafts so as not to interfere with each other.

  When the construction of the tunnels T11 to T16 is completed, unnecessary coverings L12, L12,... Of the tunnels T11 to T16 are removed according to the cross-sectional shape of the underground structure 1 as shown in FIG. Form a large space.

  Then, as shown in FIG. 2 (d), by using the linings L11, L11,... Of the tunnels T11 to T16 left along the boundary with the natural ground (that is, the outer edge of the underground structure 1). When the top plate 1A, the bottom plate 1B, and the side walls 1C and 1C are formed, the underground structure 1 is obtained. The top plate 1A, the bottom plate 1B, and the side walls 1C, 1C may be formed after removing all the unnecessary lining L12, or while removing a part of the unnecessary lining L12 of the tunnels T11 to T16, The top plate 1A, the bottom plate 1B, and the side walls 1C and 1C of the structure 1 may be constructed.

  Next, the configuration of the propelling box 10 will be described in detail with reference to FIG. The propulsion box 10 shown on the right side of FIG. 3 is used for the first tunnel T11 (see FIG. 2A), and the propulsion box 10 shown on the left side is the second tunnel T12. (See (a) of FIG. 2).

  The propelling box 10 includes an outer shell 11 formed in a rectangular tube shape, a plurality of main girders 12, 12,... Arranged adjacent to each other at a predetermined interval in the tunnel axis direction, and adjacent main girders 12, 12 A plurality of vertical ribs 13, 13,... Arranged along the tunnel axis direction.

The outer shell 11 is composed of a plurality of steel skin plates 111, 111,... Joined by welding, and has a rectangular cross section as a whole.
In addition, the upper surface and the left side surface of the outer shell 11 of the propulsion box 10 shown on the right side of FIG. 3 are formed by three large and small skin plates 111, and a gap 11a is formed between the adjacent skin plates 111, 111. Is formed. The gap 11a extends in the tunnel axis direction and serves as an opening of the guide groove D1.

  The main girder 12 is made of four steel plate members arranged in a frame shape along the inner surface of the outer shell 11, and each plate member is joined to the inner peripheral surface of the outer shell 11 by welding. Further, the main girder 12 of the propelling box 10 shown on the right side of FIG. 3 is formed with a T-shaped notch in accordance with the cross-sectional shape of the groove member 14 described later.

  The vertical rib 13 is made of a steel plate material joined to the inner peripheral surface of the outer shell 11 by welding. In addition, the edge part of the longitudinal direction of the vertical rib 13 is joined to the side surface of the main girder 12 by welding.

  Further, in the propelling box 10, both or one of the groove member 14 that becomes the guide groove D <b> 1 and the protrusion member 15 that becomes the protrusion P <b> 1 are attached in the vicinity of the corner portion of the outer shell 11. The positions and the number of the guide grooves D1 and the protrusions P1 are appropriately set according to the position of the tunnel T1.

  The groove member 14 is disposed along the gap 11 a on the inner peripheral surface of the outer shell 11. Also. As shown in FIG. 4B, the groove member 14 includes a pair of opposed pieces 141 and 141 that are opposed to each other with the gap 11a of the outer shell 11 interposed therebetween, and tip ends of the pair of opposed pieces 141 and 141, respectively. The projecting portions 142 and 142 projecting to the side and the profile 143 having a U-shaped cross section (groove shape) provided on the projecting pieces 142 and 142 are formed. A groove having a T-shaped cross section (so-called T-groove) including 14A and the wide portion 14B is formed. The opposing piece 141, the overhanging piece 142, and the shape member 143 are made of steel and are joined to each other by welding.

  As shown in FIG. 3, the projecting member 15 is disposed along the tunnel axis direction on the outer peripheral surface of the outer shell 11, and the projecting end portion projects outside the outer shell 11. Further, as shown in FIG. 4A, the protruding member 15 includes a rail 151 disposed on the outer peripheral surface of the outer shell 11, a presser plate 152 disposed on the inner peripheral surface of the outer shell 11, and the rail 151. Are provided with bolts 153, 153,... Passing through the flange 151a and the presser plate 152, and nuts 154, 154,.

  The rail 151 is made of hot stamped steel, shaped steel, cast iron, sharpened steel, etc., and has a flange 151a fixed to the outer peripheral surface of the outer shell 11, a web 151b rising from the flange 151a, and a protruding end of the web 151b. And a head 151c formed in the portion. As shown in FIG. 4B, the width (thickness) of the web 151b of the rail 151 is smaller than the width of the narrow portion 14A of the groove member 14 (that is, the opening width a of the guide groove D1). In addition, since the cross-sectional area of the head portion 151c is smaller than the cross-sectional area of the wide portion 14B of the groove member 14, the rail 151 enters the groove member 14 with a clearance that can move vertically and horizontally. That is, the rail 151 serving as the protrusion P1 is coupled with the groove member 14 serving as the guide groove D1 in a loosely fitted state. Further, the head portion 151c of the rail 151 is formed to have a width dimension larger than the width of the narrow portion 14A of the groove member 14 (that is, the opening width a of the guide groove D1). In this way, the rail 151 is prevented from coming out of the groove member 14, so that the adjacent propelling boxes 10, 10 can be prevented from being separated more than necessary.

  In the outer shell 11, an injection mechanism 112 used for water stop injection is formed in the vicinity of the groove member 14 and the vicinity of the protruding member 15 along the tunnel axis direction. The injection mechanism 112 includes a concave groove 112a formed in the outer shell 11 and a bar 112b accommodated in the concave groove 112a. The bar 112b prevents intrusion of earth and sand into the concave groove 112a, is disposed over the entire length of the concave groove 112a, and is pulled out when water is injected around the groove 112a. The water stop injection is performed using the concave groove 112a after the concave groove 112a is washed with a jet water flow. In addition, depending on the magnitude | size of a groundwater pressure, you may perform the water stop between the propulsion boxes 10 and 10 with the sealing material not shown stuck to the ditch | groove 112a. In this case, a non-inflatable sealing material such as butyl rubber is used for the propulsion box 10 of the preceding tunnel T1 (see FIG. 4B), and the propulsion box 10 of the subsequent tunnel T1 (( For the reference a), a delay type water-expandable sealing material may be used. In addition, when using a water-expandable sealing material, it is good to stick the sealing material 1.1-1.3 times the groove volume to the ditch | groove 112a, for example. If it does in this way, even if a sealing material expand | swells, initial water stop can be performed, and also long-term water stop will be achieved because a sealing material expand | swells after the predetermined number of days passes.

  Further, in the present embodiment, the injection mechanism 112 is formed in the vicinity of the groove member 14 and the projecting member 15, but the injection mechanism 112 may be formed in a place where there is no such member.

  And if each tunnel T1 (refer FIG. 2) is comprised using the propulsion box 10 comprised as mentioned above, when the preceding tunnel T1 meanders or is twisted, or the tunnel T1 of the succeeding tunnel T1. Even if rolling or pitching occurs in the excavator K (see FIG. 2 (a)), these effects are absorbed by the connecting portions of both tunnels T1 and T1, so that the construction It is possible to perform reliably.

  That is, as shown in FIG. 3, when pushing the propulsion box 10 (hereinafter referred to as “following propulsion box 10”) to be the succeeding tunnel T1 along the preceding tunnel T1, The rail 151 of the propulsion box 10 is inserted into the groove member 14 of the propulsion box 10 constituting the preceding tunnel T1 from the tunnel axis direction. As shown in FIG. Since 151 enters into the groove member 14 in a loosely fitted state, the groove member 14 can be used even if the preceding tunnel T1 meanders or the rolling machine K of the succeeding tunnel T1 is rolling. As a result, it is possible to smoothly push out the subsequent propulsion box 10.

  For example, in FIG. 5A, the excavating machine K (see FIG. 2A) of the succeeding tunnel T1 rolls, and the propulsion box 10 behind it rotates around the tunnel axis. FIG. 5B is a cross-sectional view showing the state, and FIG. 5B shows the coupling state of the rail 151 of the groove member 14 (guide groove D1) and the protrusion member 15 (protrusion P1) in the Y1 portion of FIG. As shown in this figure, since there is a clearance between the groove member 14 and the rail 151, the groove member 14 There is no inconvenience that the rail 151 immediately competes with the rail 151. As a result, the subsequent propulsion box 10 can be pushed out smoothly.

  FIG. 5 (c) shows that the propulsion box 10 behind the tunnel T1 meanders up and down with respect to the tunnel axis direction by pitching the excavating machine K (see FIG. 2 (a)) of the trailing tunnel T1. FIG. 5D is a rail of the groove member 14 (guide groove D1) and the protrusion member 15 (protrusion P1) in the Y2-Y2 cross section of FIG. 5C. In this case, there is no inconvenience that the groove member 14 and the rail 151 immediately compete with each other. As a result, the succeeding propelling box 10 can be made smooth. Can be extruded. In addition, although illustration is abbreviate | omitted, it is the same also when the propulsion machine 10 of the back is meandering right and left with respect to the tunnel axial direction because the excavation machine K of the succeeding tunnel T1 yaws.

  As shown in FIG. 4B, the groove member 14 and the rail 151 are coupled in a loosely fitted state so as to be able to cope with the meandering of the tunnel T1, while the head of the rail 151 151c (that is, the protruding end portion of the protrusion P1) is formed to have a width dimension larger than the width of the narrow portion 14A of the groove member 14 (opening width a of the guide groove D1). As a result, the underground structure 1 with high dimensional accuracy can be constructed.

  Thus, if this propulsion box 10 is used, it becomes possible to construct the underground structure 1 smoothly and accurately.

  In addition, in this embodiment, although the case where the propelling box 10 was comprised with the member made from steel was illustrated, it may be comprised by the member made from a spheroidal graphite cast iron other than this, Furthermore, It may be composed of a reinforced concrete member.

  Moreover, the structure of the groove member 14 used as the guide groove D1 and the protrusion member 15 used as the protrusion P1 is not limited to what is shown in FIG. 4 etc., You may change suitably.

(Strange Katachirei of the guide grooves and ridges)
For example, instead of these, the groove member 24 and the protruding member 25 shown in FIG. 6 may be used. The groove member 24 and the projecting member 25 are formed at the corners of the outer shell 11.

  The groove member 24 includes a pair of opposed pieces 241 and 241 opposed to each other with the gap 11a between the outer shells 11 interposed therebetween, and a cross-sectional C-shaped member 243 provided at the tip of each of the pair of opposed pieces 241 and 241. And is configured.

  The projecting member 25 is screwed into the rail 251 disposed on the outer peripheral surface of the outer shell 11, the presser plate 252 disposed on the inner peripheral surface of the outer shell 11, and the web 251b of the rail 251 from the presser plate 252 side. A bolt 253 is provided.

  Also in this protruding member 25, the width (thickness) of the web 251b of the rail 251 is smaller than the width of the narrow portion 24A of the groove member 24 (that is, the opening width of the guide groove D1), and Since the cross-sectional area of the head 251c is smaller than the cross-sectional area of the wide portion 24B of the groove member 24, the rail 251 enters the groove member 24 with a clearance that can move vertically and horizontally. That is, the rail 251 serving as the protrusion P1 is coupled with the groove member 24 serving as the guide groove D1 in a loosely fitted state. Further, since the width of the head 251c of the rail 251 is larger than the width of the narrow portion 24A of the groove member 24 (that is, the opening width of the guide groove D1), the rail 251 does not come out of the groove member 24. As a result, it is possible to prevent the adjacent propelling boxes 10 and 10 from being separated more than necessary.

  In other words, unlike the rail 151 shown in FIG. 4B, the rail 251 of the projecting member 25 does not have a flange at the base end portion, so that the adjacent propelling boxes 10 and 10 are adjacent to each other. It becomes possible to approach.

( First embodiment of the present invention )
Hereinafter, the best mode for carrying out the present invention will be described in detail. In a first embodiment of the present invention, as shown in FIG. 7, using the channel member 34 and the projecting member 35.

  The projecting member 35 includes a rail 351 that projects to the outside of the outer shell 11. The rail 351 includes a flange 351a joined to the inner peripheral surface of the outer shell 11 by welding, a web 351b rising from the flange 351a, and a head 351c having a C-shaped cross section formed at a protruding end portion of the web 351b. It has.

  Also in this protruding member 35, the width (thickness) of the web 351b of the rail 351 is smaller than the width of the narrow portion 34A of the groove member 34 (that is, the opening width of the guide groove D1), and Since the cross-sectional area of the head portion 351c is smaller than the cross-sectional area of the wide portion 34B of the groove member 34, the rail 351 enters the inside of the groove member 34 with a clearance that can move vertically and horizontally. That is, the rail 351 that becomes the protrusion P1 is coupled with the groove member 34 that becomes the guide groove D1 in a loosely fitted state.

  Further, in the projecting member 35, only the web 351b and the head 351c of the rail 351 protrude to the outside of the outer shell 11, and the flange 351a of the rail 351 is joined to the inner peripheral surface of the outer shell 11. It is possible to bring the adjacent propelling boxes 10 and 10 close to each other. The rail 351 is dimensioned and shaped so that the head 351c does not contact the profile 343 constituting the groove member 34 even when the outer shells 11, 11 of the adjacent propelling boxes 10, 10 contact each other. Molded. In this way, even if the outer shells 11 are in contact with each other, there is no inconvenience that the groove member 34 (guide groove D1) and the rail 351 (projection P1) compete with each other. As a result, it becomes possible to extrude the subsequent propelling box 10 smoothly.

  Further, since the head portion 351c is formed to have a width dimension larger than the width of the narrow portion 34A of the groove member 34 (that is, the opening width of the guide groove D1), the adjacent propelling boxes 10 and 10 are more than necessary. Can be prevented. That is, according to the projecting member 35, not only the “displacement” in the vertical direction of the adjacent propelling boxes 10, 10 but also the “displacement” in the left-right direction can be restricted.

( Second embodiment of the present invention )
In addition, the protrusion member 45 shown to (a) of FIG. 8 can be used in the location where water-stopping property does not become a problem in particular.

  The projecting member 45 mainly restrains “displacement” in the vertical direction, and includes a long rail 451 having a T-shaped cross section. The projecting member 45 is preferably used in combination with the projecting member 35 shown in FIG. 7 according to the construction order of the tunnel T1.

  As shown in FIG. 8B, the rail 451 includes a flange 451a joined to the inner peripheral surface of the outer shell 11 by welding and a web 451b rising from the flange 451a. .

(Modification of injection mechanism)
Further, in the propulsion box 10 shown in FIGS. 4A and 4B, the injection mechanism 112 is disposed on the ground mountain side from the guide groove D1 and the protrusion P1, but the present invention is not limited to this. For example, like the propulsion box 10 shown in FIG. 9, the injection mechanisms 512 and 512 may be arranged on both sides of the guide groove D1 and the protrusion P1 (joint J1). The injection mechanism 512 includes an injection tube 512b disposed along a concave groove 512a formed in the outer shell 11. If it does in this way, the circumference of joint J1 can be stopped reliably.

  In addition, as shown in FIG. 10, you may arrange | position the injection | pouring mechanisms 512 and 512 in the location without the coupling J1 (refer FIG. 9).
