[0002] With the continuous development of urban construction, many regions have successively begun to develop subway networks and are paying increasing attention to the development and utilization of urban underground space. In addition, the renovation of urban water supply and drainage systems and the laying of underground utility tunnels are also important aspects of urban construction.
[0003] The above-mentioned urban construction projects all involve tunnel construction. Mechanical tunneling is a commonly used method in tunnel construction, and tunnel lining segments are crucial assembly components used in mechanical tunnel construction. Tunnel lining segments form the inner barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. As the permanent lining structure of the tunnel, they directly affect the overall quality and safety of the tunnel.
[0004] Tunnel construction often involves the construction of side passages. For example, according to the "Metro Design Code", when the continuous length of two single-track tunnels is greater than 600m, a connecting passage should be provided. The connecting passage is a typical side passage.
[0005] To create a bypass tunnel within a tunnel, holes need to be cut into the tunnel segments at the location of the bypass. Conventional tunnel segments are reinforced concrete structures with high steel density and high concrete strength, making them difficult to cut using tunnel boring machines (TBMs) and thus unsuitable for mechanical bypass excavation. Therefore, providing a tunnel segment design that facilitates bypass drilling is a problem that needs to be solved by those skilled in the art. Utility Model Content
[0006] Therefore, this utility model provides a segment, a segment ring assembly, and a tunnel structure for mechanical bypass drilling construction, in order to solve the technical problem that segments are not suitable for mechanical bypass excavation operations in the prior art.

[0010] In any of the above technical solutions, the frame structure includes: an arc plate having a notch for forming a notch; a surrounding plate surrounding and connected to the edge of the arc plate; wherein a first connecting hole is provided in the surrounding plate, and a cuttable structure is inserted into the area defined by the arc plate and the surrounding plate.
[0011] In any of the above technical solutions, the frame structure further includes: a tenon and a mortise provided on the enclosure panel; and / or the frame structure further includes: a sealing groove provided on the enclosure panel.
[0012] In any of the above technical solutions, the frame structure further includes: multiple ribs, which protrude outward from the inner surface of the arc plate; wherein the multiple ribs intersect each other to separate multiple grid structures on the inner surface of the arc plate.
[0013] In any of the above technical solutions, the frame structure further includes: a casting hole provided on the arc plate, the casting hole being used to cast concrete into at least a portion of the grid structure; and / or the frame structure further includes: a lifting arm hole provided on the arc plate and / or the rib plate, the lifting arm hole being used to hoist the segments; and / or the frame structure further includes: a grouting hole provided on the arc plate, the grouting hole being arranged around the edge of the notch; and / or the frame structure further includes: an extending rib provided on at least a portion of the rib plate, the extending rib plate protruding outward from the surface of the rib plate away from the arc plate.

[0017] Beneficial effects
[0018] This invention utilizes a hybrid structure comprised of a machinable structure and a concrete structure on the tunnel segments. This allows for easier cutting at the notches in the segments, enabling tunnel boring machines (TBMs) and other equipment to more easily perform cutting and drilling operations.

Detailed Implementation
[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] This invention provides a tunnel segment for mechanical bypass drilling construction, which forms part of a segment ring assembly. During tunnel construction, tunneling equipment, such as a tunnel boring machine (TBM), excavates the tunnel and carries, transports, and grabs tunnel segments, assembling them along the tunnel's inner wall. Multiple tunnel segments are joined circumferentially along the TBM to form a ring-shaped segment assembly, and multiple segment ring assemblies are joined axially (i.e., the tunnel's extension direction) along the TBM to form the tunnel's inner wall. Tunnel construction often involves the creation of bypasses (e.g., connecting passages in subway networks are typical bypasses). If a bypass is to be created in a tunnel, holes need to be drilled in the tunnel segments at the bypass location, and further excavation along these holes forms the bypass. In tunnel structures, tunnel segments that require drilling for bypass construction are referred to as "special tunnel segments." The tunnel segment provided by this invention is precisely a "special tunnel segment" used for bypass drilling construction.
[0036] Drilling of the aforementioned "special tunnel segments" can generally be carried out by tunneling equipment or manually. Regardless of the drilling method, the existing technology faces the following problems: conventional tunnel segments are reinforced concrete structures with high steel reinforcement density and high concrete strength, making it difficult to use equipment such as tunnel boring machines for cutting operations. Manual excavation and drilling are also not easy to carry out, and drilling can easily cause the "special tunnel segments" to break or be damaged.
[0037] One of the objectives of this invention is to provide a segment for easy bypass drilling construction, enabling tunnel boring machines and other equipment to perform cutting and drilling operations more easily, thereby improving construction efficiency, protecting the equipment cutter head, and preventing the segment from breaking or being damaged due to violent excavation and drilling.
[0038] like Figure 1 As shown, multiple segments 100 of this invention can be used together to form a single unit, serving as a "special segment". A drilling operation can then be performed in the central area of this "special segment" to form a cutting hole 200. The shape and size of the cutting hole 200 can be selected and adjusted according to the size and shape of the bypass channel. For example, the cutting hole 200 can be circular, elliptical, rectangular, rectangular-like with rounded corners, polygonal, etc. Figure 12 and Figure 13 This demonstrates the case where the cutting hole 200 is circular.
[0039] In addition to using multiple segments 100 of this invention to form a "special segment", a single segment of this invention can also be used directly as a "special segment". In this case, a drilling operation is required in the central area of the segment of this invention to form a cutting hole.
[0040] like Figure 2 and Figure 3 As shown, the segment 100 of this utility model includes a frame structure 110. The frame structure 110 is the main structure of the segment 100, which acts as a skeleton to provide structural strength for the segment 100. Preferably, the frame structure 110 is a metal frame.
[0041] like Figure 6 and Figure 7 As shown, the frame structure 110 has a notch 110a. The location and size of the notch 110a can be determined based on the position of the segments 100 during splicing and the size requirements of the bypass passage. Figure 1 The case where both the cutting hole 200 and the notch 110a are rectangular is shown. Figure 12 and Figure 13 The case shown is where the cutting hole 200 is circular and at least part of the edge of the notch 110a is arc-shaped.
[0042] For example, two, four, six, or eight segments 100 can be used together to form a single unit, referred to as a "special segment". Figure 2 and Figure 3 Taking a structure where 6 segments (100mm each) together form a whole as an example: For Figure 2 and Figure 3 For the four segments 100 at the left and right corners, the shape of their notches 110a is as follows: Figure 6 As shown; for Figure 2 and Figure 3 Regarding the two segments 100 in the middle position, the shape of the notch 110a is as follows: Figure 7 As shown. Preferably, the notch 110a is formed in the shape of a rectangle, a near-rectangular shape, a circle, a near-circular shape, or a sector.
[0043] The function of notch 110a is to form at least a portion of the cutting hole 200 for the drilling operation. For example... Figure 2 As shown, when the six segments 100 together form a whole, the notches 110a of each segment 100 together form a complete rectangle. Figure 1 As shown, after the drilling operation, a hole was formed in the rectangular position.
[0044] like Figure 4 and Figure 5 As shown, to facilitate cutting and drilling of the segment 100, the segment 100 also includes a machinable structure 120, which fills the gap 110a. Compared to the frame structure 110, the machinable structure 120 has lower strength and hardness, and is therefore easier to cut.
[0045] like Figures 6 to 8 As shown, a first connecting hole 110b is provided at the edge of the notch 110a. The machinable structure 120 is inserted into the frame structure 110 through the first connecting hole 110b to achieve the initial connection between the machinable structure 120 and the frame structure 110.
[0046] It should be noted that, Figures 6 to 8 The location of the first connecting hole 110b is shown. Figure 9 The shape of the first connecting hole 110b is shown. Those skilled in the art will understand that the first connecting hole 110b is specifically formed as a through hole, and its outline shape can be any shape such as a circle, rectangle, or other polygons, as long as the machinable structure 120 can be inserted into it. There are multiple first connecting holes 110b, which are distributed along the edge of the notch 110a. The multiple first connecting holes 110b can be arranged in an orderly, equidistant manner or in a disordered, non-equidistant manner.
[0047] The machinable structure 120 specifically comprises intertwined fiber cages or fiber strips. The cages or strips can be arranged transversely, longitudinally, or crisscrossed. They can be arranged in an orderly manner or intertwined randomly. This is understandable. Figure 4 and Figure 5 The machinable structure 120 shown is schematic and does not necessarily represent an interlaced mesh structure. A portion of the rib cages or ribs in the machinable structure 120 is inserted into the frame structure 110 via the first connecting hole 110b. Preferably, the machinable structure 120 is made of machinable fiber, and the material of the machinable fiber is at least one or a combination of glass fiber, basalt fiber, carbon fiber, and metal fiber. Besides directly inserting the machinable structure 120 in the form of fiber rib cages or ribs into the first connecting hole 110b, bolts made of machinable material can also be provided on the machinable structure 120, thereby bolting the machinable structure 120 to the frame structure 110 via the first connecting hole 110b.
[0048] In addition to the frame structure 110 and the machinable structure 120, the segment 100 of this utility model also includes a concrete structure 130, which is poured into the notch 110a to enclose at least a portion of the machinable structure 120 within the notch 110a.
[0049] It should be noted that when multiple segments 100 are used together to form a whole as a "special segment", this utility model can place multiple frame structures 110 belonging to different segments 100 together in the mold, place a machinable structure 120 at the position of the large gap formed by the gaps 110a belonging to multiple segments 100, and then pour concrete at this position to form a concrete structure 130.
[0050] Preferably, the concrete structure 130 not only fills the large gap formed by the joint assembly of multiple gaps 110a belonging to different segments 100, but also fills the grid of multiple frame structures 110 belonging to different segments 100, thereby improving the tightness of the connection between the machinable structure 120 and the frame structure 110. It can be understood that the concrete structure 130 is obtained by concrete pouring. In the prior art, the concrete structure is an important component of the segment, providing structural strength and waterproofing. In the segment 100 of this invention, the concrete structure 130, in addition to the above-mentioned functions, can also fix the machinable structure 120 within the gaps 110a of the frame structure 110, so that the frame structure 110, the machinable structure 120, and the concrete structure 130 form a whole. As mentioned above, the machinable structure 120 is specifically intertwined fibers or ribs, and the concrete structure 130 can fill the gaps between the rib cages or ribs. The hybrid structure of the machinable structure 120 and the concrete structure 130 not only improves the structural strength of the segment 100 at the cutting position, but also makes it relatively easy to cut and drill holes at the cutting position of the segment 100.
[0051] In summary, this utility model, by setting a hybrid structure consisting of a machinable structure 120 and a concrete structure 130 on the tunnel segment 100, makes it relatively easy to cut the notch 110a of the tunnel segment 100. This allows equipment such as tunnel boring machines to more easily cut and drill holes in the tunnel segment 100, thereby improving construction efficiency, protecting the equipment cutter head, and preventing the tunnel segment 100 from breaking or being damaged due to violent excavation and drilling.
[0052] Furthermore, if the non-cutting portion of the segment is set as a reinforcing cage, and the portion to be cut is set as a fiber cage, such as glass fiber or carbon fiber, and the reinforcing cage and fiber cage are tied together before pouring concrete, a segment with a specific machinable structure can also be obtained. However, the above technical solution has the problem that since both the non-cutting portion and the portion to be cut are reinforcing cage structures, it is difficult to directly insert them together, and the binding connection is inconvenient, complex, and labor-intensive, reducing construction efficiency. In contrast, this utility model sets the non-cutting portion of the segment 100 as a frame structure 110. The frame structure 110 is made of interconnected plates and has a box-shaped structure. It not only has better structural strength than the reinforcing cage structure, but can also be machined with a regularly shaped first connecting hole 110b. Therefore, it is only necessary to insert some of the reinforcing bars of the machinable structure 120 into the first connecting hole 110b to achieve the initial fixation of the machinable structure 120 and the frame structure 110. Subsequently, the machinable structure 120 and the concrete structure 130 are mixed by pouring concrete. Compared to the traditional binding connection method, the structural improvements to the segment 100 in this invention make the processing more convenient, shorten the processing cycle, increase efficiency, and improve the structural strength of the segment. It should also be noted that the main body of the segment 100 in this invention is a frame structure 110, which is typically made of a metal material such as stainless steel. The frame structure 110 can be machined on a machine tool, therefore, in the casting process, the precision requirements for the mold are lower, and the machining cycle is shorter. Therefore, using the segment 100 of this invention can shorten the construction period.
[0053] Preferably, the concrete structure 130 of this utility model is not only poured into the gap of the machinable structure 120, but also poured into the frame structure 110, and encloses at least part of the machinable structure 120 inserted into the frame structure 110.
[0054] In other words, this utility model uses concrete to pour both the non-cutting part and the cutting part of the segment 100. This not only improves the structural strength of the segment 100, but also further enhances the tightness of the connection between the cuttable structure 120 and the frame structure 110, ensuring that the segment 100 is stable and durable.
[0055] In one embodiment of this invention, concrete can be poured for the entire area and structure above the frame structure 110. In other embodiments of this invention, concrete can be poured only for a portion of the area or part of the structure above the frame structure 110.
[0056] For example, such as Figure 8As shown, the frame structure 110 has a second connecting hole 110c and a hand hole 110d. The second connecting hole 110c is located at the edge of the frame structure 110 and its function is to connect the segment 100 of this invention to other segments via connectors. As mentioned above, multiple segments can be assembled to form a ring-shaped segment group, and multiple segment groups can be assembled to form a tunnel structure. The second connecting hole 110c can be used to connect the segment 100 of this invention to segments belonging to the same segment group, or it can be used to connect the segment 100 of this invention to segments belonging to adjacent segment groups. The hand hole 110d is formed as a recess on the surface of the frame structure 110 and communicates with the second connecting hole 110c. Since the connection method between segments is to insert connectors such as studs into the connecting holes of the two segments and then fix them, the hand hole 110d facilitates the operator to insert stud connectors into the second connecting hole 110c of the segment 100.
[0057] Among them, such as Figure 8 As shown, the second connecting hole 110c and the hand hole 110d are disposed in the first region of the frame structure 110 (i.e., Figure 8 The area outlined by the dashed line is where the concrete structure 130 is poured, outside the first area. The first area refers to the region containing the second connecting hole 110c and the handhole 110d, and it does not have a specific shape or location. The purpose of this scheme is to leave the area containing the second connecting hole 110c and the handhole 110d unpoured with concrete, ensuring that the second connecting hole 110c remains unobstructed and that construction personnel can easily perform installation operations through the handhole 110d.
[0058] Preferably, such as Figure 5 As shown, the frame structure 110 includes an arc plate 111 and a surrounding plate 112. The arc plate 111 has a notch for forming a notch 110a. It can be understood that the arc plate 111 is a bent arc-shaped plate with a notch at its edge, the shape of which matches the notch 110a. The specific shape and size can be selected and adjusted according to the size and shape of the side passage. The surrounding plate 112 surrounds and connects to the edge of the arc plate 111, forming a box shape together with the arc plate 111, thus constituting the main body of the frame structure 110. As described above, a first connecting hole 110b for the through which the machinable structure 120 passes is provided in the surrounding plate 112, thereby allowing the machinable structure 120 to be inserted into the area defined by the arc plate 111 and the surrounding plate 112.
[0059] The arc plate 111 and the surrounding plate 112 can be connected to each other by welding or bonding. The arc plate 111 and the surrounding plate 112 can jointly enclose to form a box shape, which ensures the structural strength and facilitates the casting construction and demolding after casting.
[0060] Preferably, such as Figure 5 and Figure 6 As shown, the enclosure 112 includes side plates 1121 and end plates 1122. The side plates 1121 are arranged in pairs on either opposite side of the arc plate 111, and the end plates 1122 are arranged in pairs on the opposite side of the arc plate 111 relative to either opposite side. The side plates 1121 are used to connect the segment 100 to another segment belonging to an adjacent segment ring group, and the end plates 1122 are used to connect the segment 100 to another segment belonging to the same segment ring group.
[0061] Preferably, such as Figure 9 As shown, the frame structure 110 also includes a tenon 113 disposed on the enclosure 112. The tenon 113 is specifically a recess and / or protrusion formed on the outer wall of the enclosure 112. The tenon 113 facilitates the tenon connection between the segment 100 of this invention and adjacent segments, thereby improving the strength of the segment ring assembly or tunnel structure.
[0062] Preferably, such as Figure 9 As shown, the frame structure 110 also includes a sealing groove 114 disposed on the enclosure 112. The sealing groove 114 is specifically a strip-shaped groove formed on the outer side wall of the enclosure 112, which is used to install a sealing strip to improve the waterproof sealing effect of the pipe segment 100 of this utility model.
[0063] It is understood that the tenon 113 and the sealing groove 114 can be provided on the side plate 1121 or on the end plate 1122. The tenon 113 and the sealing groove 114 can be provided on the same surrounding plate 112 or on different surrounding plates 112. Both the tenon 113 and the sealing groove 114 can be provided on all the surrounding plates 112 of the segment 100, or only on some of the surrounding plates 112 of the segment 100. Preferably, the sealing groove 114 is provided on the end plate 1122, and the tenon 113 is provided on the side plate 1121.
[0064] It should be noted that, for example, the tenon 113 and the sealing groove 114 are provided on the frame structure 110 in this utility model. In other words, the tenon 113 and the sealing groove 114 of the segment 100 provided by this utility model are all machined by cutting, rather than being formed on the concrete structure 130 by grouting. Cutting can improve the machining accuracy of the tenon 113 and the sealing groove 114, and improve the sealing performance and assembly tightness of the segment 100 after assembly.
[0065] Preferably, such as Figure 9 and Figure 10As shown, the frame structure 110 also includes multiple ribs 115, which protrude outward from the inner surface of the arc plate 111. The multiple ribs 115 intersect each other to create multiple grid structures 110e on the inner surface of the arc plate 111. The ribs 115 enhance the structural strength of the segment 100 and strengthen the connection between the frame structure 110 and the concrete structure 130.
[0066] Preferably, such as Figure 6 and Figure 7 As shown, the frame structure 110 also has casting holes 110f disposed on the arc plate 111. The casting holes 110f are used to pour concrete structure 130 into at least a portion of the grid structure 110e. Preferably, there are multiple casting holes 110f. Figure 8 As shown, the pouring holes 110f can be arranged at intervals along a straight line on the frame structure 110. Setting the pouring holes 110f on the frame structure 110 facilitates the simultaneous pouring of concrete for both the non-cutting and cutting sections of the segment 100. The pouring holes 110f are mainly used for large-area pouring before the excavation of the main tunnel and connecting passages.
[0067] Preferably, such as Figure 2 and Figure 4 As shown, the frame structure 110 also has grouting holes 110i disposed on the arc plate 111. The grouting holes 110i are arranged around the edge of the notch 110a. More preferably, there are multiple grouting holes 110i, equidistantly spaced along the edge of the notch 110a. The grouting holes 110i are used for precise water-stopping grouting during and after the construction of the connecting passage. By setting the grouting holes 110i, precise water-stopping can be achieved and the amount of water-stopping grouting required can be reduced.
[0068] It can be understood that the above-mentioned casting process is achieved as follows: the machinable structure 120 is inserted into the first connecting hole 110b of the frame structure 110 to initially connect the two; the basic frame formed by the frame structure 110 and the machinable structure 120 is placed into the casting mold, with the side of the frame structure 110 with the casting hole 110f facing upwards; concrete is poured into the frame structure 110 through the casting hole 110f, and concrete can be directly poured into the part with the machinable structure 120; after the concrete dries and sets, it is demolded to obtain the segment of this utility model.
[0069] Preferably, such as Figure 8 As shown, the frame structure 110 also has a lifting arm hole 110g located on the arc plate 111 and / or the rib plate 115. The lifting arm hole 110g is used for hoisting the segment 100 so as to transport and move the segment 100.
[0070] Preferably, such as Figure 6 and Figure 7As shown, the frame structure 110 also includes an extension rib 116 disposed on at least a portion of the ribs 115. The extension rib 116 protrudes outward from the surface of the rib 115 away from the arc plate 111. Thus, the extension rib 116 and the rib 115 connected thereto together form a reinforcing structure with a "T"-shaped cross-section to further improve the structural strength of the segment 100.
[0071] This utility model also provides a segment ring assembly, which includes the segment 100 as described in any of the above technical solutions, and therefore has all the beneficial effects of the segment 100 as described in any of the above technical solutions, which will not be repeated here.
[0072] This utility model also provides a tunnel structure, which includes the above-mentioned segment ring assembly, and therefore has all the beneficial effects of the above-mentioned segment ring assembly, which will not be repeated here.
[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
