Description

Technical Field

[0001] This invention relates to a longitudinal joint connection device for shield tunnel segments, lining segments and their construction method, specifically to a connection node structure and usage method for longitudinal joints of shield tunnel lining segments, belonging to the technical field of shield tunnel design and construction application in civil engineering. Background Technology

[0002] With the rapid development of my country's economy and the accompanying large-scale civil engineering construction, shield tunnels have been widely used in the construction of subways, municipal works, railways, highways, and water conservancy projects due to their fast construction speed and minimal disturbance. A shield tunnel is a circular or non-circular tunnel formed by assembling and connecting prefabricated segments through a tunnel boring machine (TBM). Currently, the main connection methods for shield tunnel segment joints, especially longitudinal joints, include bent bolt connections, straight bolt connections, oblique bolt connections, and cross-cutting (CT) joints. Bent bolt joints have weak mechanical properties and are mostly used for connecting thin segments in small-to-medium diameter shield tunnels. Straight bolts have good mechanical properties, but the hand-drilled holes significantly weaken the overall structure of the segment; however, they are mostly used for connecting thicker segments in large-diameter shield tunnels. Oblique bolts have moderate mechanical properties and are easy to install, and are often used for connecting thicker segments in large shield tunnels; however, they have insufficient mechanical properties for joints with high deformation control requirements. CT joints have high stiffness, but extremely high requirements for construction error control make construction inconvenient; large construction errors can lead to difficulties in subsequent construction. In addition, there are very few joint connection forms with double-bent bolts or combinations of bent and straight bolts, but they are rarely used because the presence of hand holes can significantly weaken the thickness of the segments, affecting the overall performance of the segments, and the construction process is complex. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a shield tunnel segment longitudinal joint connection device, which is used to quickly and conveniently connect the longitudinal joints of shield tunnel segments, strengthen the joint stiffness and strength of the segment longitudinal joints, thereby improving the overall mechanical properties of the ring shield tunnel and ensuring that the overall deformation of the tunnel meets the requirements of safe operation.

[0004] Meanwhile, the present invention provides another shield tunnel segment longitudinal joint connection device. This device firstly increases the connection mechanical properties of the longitudinal joint of the segment to ensure the strength and rigidity requirements of the ring tunnel. Secondly, it does not weaken the overall performance of the segment thickness. Furthermore, it is convenient and fast to construct, and facilitates mechanized assembly using a shield machine.

[0006] Meanwhile, the present invention provides a construction method for lining segments pre-embedded with the shield tunnel segment longitudinal joint connection device of the present invention.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A shield tunnel segment longitudinal joint connection device includes a connecting member with a length equal to the width of the lining segment pre-embedded on the edge of the longitudinal joint of the lining segment. The connecting member is fixed inside the lining segment by anchors. The connecting member has an inner cavity.

The rectangular cavity constitutes the insertion part for inserting another lining segment. After insertion, the two semi-circular cavities form a circular cavity.

[0010] The outer edge of the rectangular cavity is flush with the longitudinal joint edge of the lining segment.

[0011] The semi-circular cavity is replaced with a rectangular cavity. After insertion, the two rectangular cavities form a square cavity.

[0012] O-shaped components are either circular parts that fit into a circular cavity formed by two semi-circular cavities, or square parts that fit into a square cavity formed by two rectangular cavities.

The connecting component includes a C-shaped component, and the connecting member includes an I-shaped component adapted to the inner cavity of the C-shaped component. The C-shaped component includes a body that is completely embedded inside the lining segment. The outer edge of the body is flush with the longitudinal joint edge of the lining segment. The body has a C-shaped cavity or a square cavity with an opening facing the longitudinal joint edge. The opening of the C-shaped cavity or the square cavity extends towards the longitudinal joint edge to form an I-shaped channel. The I-shaped component is an I-shaped component that is large at both ends and small in the middle and is integrally connected. The two ends of the I-shaped component are circular or rectangular components adapted to the C-shaped cavity or the square cavity. The middle of the I-shaped component is a cylindrical component that is adapted to the I-shaped channel and integrally connected to both ends.

[0017] The anchors are anchoring steel bars that are evenly distributed along the length of the C-shaped member. The anchors are connected to the C-shaped member by welding in a single-limb or double-limb manner on the cross section of the C-shaped member.

Detailed Implementation

[0024] The following detailed description of a shield tunnel segment longitudinal joint connection device and method according to the present invention, in conjunction with the accompanying drawings and specific embodiments, provides further insight.

[0025] Example 1 like Figure 1As shown, a shield tunnel segment longitudinal joint connection device, which can be figuratively described as a GOG joint device, is used to quickly and conveniently connect the longitudinal joints of shield tunnel segments, strengthen the joint stiffness and strength of the segment longitudinal joints, thereby improving the overall mechanical performance of the ring shield tunnel and ensuring that the overall deformation of the tunnel meets the requirements for safe operation.

[0026] like Figure 8 As shown, a shield tunnel segment longitudinal joint connection device includes: a lining segment 1 pre-embedded with G-type components 22; during the assembly of the lining segment 1, after the lining segment 1 is assembled to form a longitudinal joint, two G-type components 22 are inserted into each other to form an inner cavity; and an O-type component 23 is longitudinally inserted into the inner cavity formed by the two G-type components 22.

[0027] The construction process mainly involves the following steps: (1) such as Figure 5 As shown, during the prefabrication of the lining segment 1, a G-shaped component 22 with a length equal to the width of the lining segment 1 is pre-embedded in the longitudinal joint. The opening of the G-shaped component 22 faces the outside of the longitudinal joint of the lining segment 1, and attention should be paid to the anti-symmetrical relationship between the upper and lower G-shaped components 22 pre-embedded in the longitudinal joints of adjacent lining segments 1.

[0028] (2) such as Figure 6 As shown, during the ring assembly process of the pipe segments, the first positioning lining pipe segment 1 is placed first, and the second lining pipe segment 1 is assembled with the first lining pipe segment 1 to form a longitudinal joint. The two anti-symmetrical G-shaped components 22 are closely attached to form an inner cavity.

[0029] (3) such as Figure 7 As shown, the O-shaped component 23 with the corresponding inner hole shape is inserted longitudinally into the two closely fitted G-shaped components 22 to form an inner hole cavity, thus forming a longitudinal seam connector.

[0030] A G-shaped component 22 is pre-embedded in the lining segment 1 along the longitudinal joint edge of the lining segment 1 using anchors 4. Similarly, another G-shaped component 22 is pre-embedded in another lining segment 1 along the longitudinal joint edge of the lining segment 1 using anchors 4. After the longitudinal joint of the segments is assembled, the two G-shaped components 22 form a circular or square cross-section hole. Then, a corresponding circular or square cross-section steel component is inserted into the circular or square hole formed by the two G-shaped components 22 to form a longitudinal joint connection of the segments that can withstand tensile, compressive, and shear forces.

[0031] Specifically, a G-shaped component 22 is pre-embedded in each of the lining segments 1 on both sides of the longitudinal joint of the shield tunnel segments. The two G-shaped components 22 form a circular or square cross-section hole in the longitudinal joint formed by the assembly of two lining segments 1. A circular or square cross-section steel component (such as a circular steel component) is inserted into the opening. Figure 3The O-shaped component 23 shown makes the longitudinal joint a GOG stress-bearing whole for tensile, compressive and shear forces, thereby improving the overall mechanical properties of the ring shield tunnel segments in terms of strength and stiffness.

[0032] like Figure 2 As shown, the cross-sectional shape of the G-type component 22 is an open G-shape on the outside and an open circle or square shape on the inside.

[0033] Specifically, the G-type component 22 includes a square body 2201 that is half-embedded inside the lining segment 1. A semi-circular cavity 2202 is provided inside the square body 2201. The part of the square body 2201 where the semi-circular cavity 2202 is located constitutes the upper part 2203 of the G-type component 22. The part of the upper part 2203 that protrudes from the lining segment 1 constitutes the insertion part 2204. The opening of the semi-circular cavity 2202 is connected to a rectangular cavity 2205. The rectangular cavity 2205 constitutes the insertion part 2206 for inserting another lining segment 1 into the insertion part 2204. After insertion, the two semi-circular cavities 2202 form a circular cavity. The outside of the rectangular cavity 2205 is flush with the longitudinal seam edge of the lining segment 1.

[0034] The semi-circular cavity 2202 can be replaced with a rectangular cavity. After insertion, the two rectangular cavities form a square cavity.

[0035] O-shaped component 23 is either a circular component that fits into a circular cavity formed by two semi-circular cavities 2202, or a square component that fits into a square cavity formed by two rectangular cavities.

[0036] like Figure 4 As shown, anchor 4 is an anchoring steel bar that is evenly distributed along the length of G-shaped member 22, and its diameter and length must meet the requirements for calculating anchoring force.

[0037] The connection method between anchor 4 and G-type component 22: the G-type component 22 can be a single limb or a double limb, and is connected to the G-type component 22 by welding.

[0038] like Figure 3 As shown, the cross-sectional shape of the O-type component 23 can be circular, rectangular, or other shapes that match the inner cavity of the G-type component 22, and a construction gap is provided to facilitate insertion.

[0039] O-type component 23 connection method: The steps in the construction process are as follows: (1) embed the G-type component 22 and the anchor 4 in the longitudinal joint of the precast lining segment 1; (2) when assembling the lining segment 1, the longitudinal joint of the later lining segment 1 is aligned with that of the earlier lining segment 1, and the embedded G-type component 22 is inserted into the opening to form a circular or square cavity; (3) insert the O-type component 23 into the cavity formed by the two G-type components 22 to form an integral connection device.

[0040] G-shaped member 22 is preferably a steel member with a G-shaped cross section, and O-shaped member 23 is preferably a steel member with an O-shaped cross section.

[0041] Compared with the prior art, the main advantages of this embodiment include: (1) This embodiment can improve the joint stiffness and bearing capacity of the longitudinal joint of the shield tunnel, thereby reducing the overall elliptic deformation of the segment. Especially for large-diameter thick segments, it can be combined with bent bolts or oblique bolts to form a composite connection form of the longitudinal joint of the segment with greater stiffness and better bearing capacity.

[0042] (2) In this embodiment, no hand holes are provided on the segments, which will not cause the segment thickness to become thinner in some areas and weaken the segment performance.

[0043] (3) This embodiment facilitates mechanized assembly using a tunnel boring machine, resulting in rapid construction, simple construction steps, and easy assurance of construction quality. It can be widely used in tunnel boring machine engineering.

[0044] Example 2 like Figure 9 As shown, a shield tunnel segment longitudinal joint connection device, which can be figuratively described as a CIC joint device, is used to quickly and conveniently connect the longitudinal joints of shield tunnel segments, strengthen the joint stiffness and strength of the segment longitudinal joints, thereby improving the overall mechanical performance of the ring shield tunnel and ensuring that the overall deformation of the tunnel meets the requirements for safe operation.

[0045] like Figure 16 As shown, a shield tunnel segment longitudinal joint connection device includes: a lining segment 1 with a pre-embedded C-shaped component 2, an I-shaped component 3 that can be inserted into the open cavity of two closely fitted opposing C-shaped components 2, and an anchor 4 for fixing the C-shaped component 2.

[0046] During the assembly of the lining segment 1, after the lining segment 1 is assembled to form a longitudinal joint, an I-shaped component 3 is longitudinally inserted into the inner cavity of the opening of two C-shaped components 2 that are closely fitted to each other.

[0047] The construction process mainly involves the following steps: (1) such as Figure 13 As shown, during the prefabrication of the lining segment 1, a C-shaped component 2 with a length equal to the width of the lining segment 1 is pre-embedded in the longitudinal joint of the lining segment 1, with the opening of the C-shaped component 2 facing the outside of the longitudinal joint of the lining segment 1.

[0048] (2) such as Figure 14 As shown, during the ring assembly process of the lining segment 1, the first positioning lining segment 1 is placed first, and the second lining segment 1 is assembled with the first lining segment 1 to form a longitudinal joint, with the two C-shaped components 2 closely fitted to each other.

[0049] (3) such as Figure 15As shown, the I-type component 3 is inserted longitudinally into the wall of two closely fitted and opposite C-type components 2 to form a longitudinal joint connection.

[0050] A C-shaped component 2 is pre-embedded in the lining segment 1 along the longitudinal joint edge of the lining segment 1 using an anchor 4. Similarly, another C-shaped component 2 is pre-embedded in another lining segment 1 along the longitudinal joint edge of the lining segment 1 using an anchor 4. After the longitudinal joint of the lining segment 1 is assembled, the openings of the two C-shaped components 2 are tightly joined together. Then, an I-shaped component 3 is inserted into the openings of the two C-shaped components 2 to form a whole segment longitudinal joint connection bearing the load.

[0051] Specifically, a C-shaped component 2 is pre-embedded in each of the lining segments 1 on both sides of the longitudinal joint of the shield tunnel segments. The two C-shaped components 2 have openings facing each other in the longitudinal joint formed by the two lining segments 1. An I-shaped component 3 is inserted into the opening, so that the longitudinal joint forms a CIC stress-bearing whole with improved strength and stiffness, thereby improving the overall mechanical performance of the ring shield tunnel segments.

[0052] like Figure 10 As shown, the cross-sectional shape of C-type component 2 is an open square or arc shape; the inner cavity is an open circle or square shape, and the opening of the inner cavity extends horizontally to the outside of the longitudinal seam.

[0053] like Figure 12 As shown, anchor 4 is an anchoring steel bar that is evenly distributed along the length of C-shaped member 2, and its diameter and length must meet the requirements for calculating anchoring force.

[0054] The connection method between the anchor 4 and the C-shaped component 2 is as follows: the C-shaped component 2 can be a single limb or a double limb on its cross section, and is connected to the C-shaped component 2 by welding.

[0055] like Figure 11 As shown, the cross-section of the I-shaped component 3 is I-shaped with large ends and small middle. The shape of the large ends can be circular, rectangular, or other shapes that match the inner cavity of the C-shaped component 2, and a construction gap is provided to facilitate insertion.

[0056] Connection method of type I component 3: The steps in the construction process are as follows: (1) embed type C component 2 and anchor 4 in the longitudinal joint of the precast lining segment 1; (2) when assembling lining segment 1, the longitudinal joint of the later lining segment 1 is aligned with that of the earlier lining segment 1, and the opening of the embedded type C component 2 is closely fitted and aligned; (3) insert type I component 3 into the inner cavity of the two type C component 2 to form a connector.

[0057] C-shaped component 2 is preferably a C-shaped steel component, and I-shaped component 3 is preferably an I-shaped steel component.

[0058] Compared with the prior art, the main advantages of this embodiment include: (1) This embodiment can improve the joint stiffness and bearing capacity of the longitudinal joint of the shield tunnel, thereby reducing the overall elliptic deformation of the lining segment 1. Especially for large-diameter thick segments, it can be combined with bent bolts or oblique bolts to form a composite connection form of the longitudinal joint of the segment with greater stiffness and better bearing capacity.

[0059] (2) In this embodiment, no handholes are provided on the lining segment 1, which will not cause the segment thickness to become thinner locally and weaken the segment performance.

[0060] (3) This embodiment facilitates the use of tunnel boring machines to achieve rapid mechanized assembly and construction. The construction steps are simple and the construction quality is easy to ensure. It can be promoted and used in tunnel boring machine engineering.
