Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering auxiliary equipment, in particular to a tunnel segment assembly. Background Art

[0002] With the rapid economic development and the vigorous promotion of urban construction, urban underground transportation rails have become public transportation for the connection and development between cities. Due to the complexity of underground tunnel construction, there are many difficulties and obstacles to construction, especially the installation of segment supports while the shield machine is working in the tunnel, which is the key and difficult point of current underground engineering construction.

[0003] Conventional tunnel segment construction generally uses a segment hanging machine to transport the segment to a fixed position, uses the machine to gradually adjust the position of the segment, aligns the segment with the segment of the previous section, and slowly fits the segment to the tunnel wall after the shield machine construction. When the two segments are aligned, the construction workers manually bolt the segments together. The applicant has found that the conventional construction method has at least the following disadvantages:

[0004] When connecting bolts are not installed between the segments, it is impossible to determine whether the segments are misaligned or flush. As a result, when two segments are installed and fixed by bolts, if a misalignment problem is found between the segments, it is necessary to remove the connecting bolts between the segments, adjust the position of the segments by machine and then reinstall them. If the segments are reworked and adjusted for a second time after installation, it is not only time-consuming and labor-intensive, but also cannot ensure that the segment installation meets qualified quality requirements, which indirectly increases the cost of construction. Conventional segment installation and adjustment requires the cooperation of two or more people. If the misalignment problem still exists after installation, it may cause the segments in the tunnel to be installed in a loose joint, resulting in a risk of water leakage in the later stage. Utility Model Content

[0005] The purpose of the utility model is to provide a tunnel segment assembly to solve the problem in the prior art that when the connecting bolts are not installed between the segments, it is impossible to determine whether the segments are misaligned or flush, resulting in the fact that when two segments are installed and fixed by bolts, if there is a misalignment problem between the segments, it is necessary to remove the connecting bolts between the segments, adjust the position of the segments by machine, and then reinstall them. If the segments are reworked and adjusted for a second time after installation, it is not only time-consuming and labor-intensive, but also cannot ensure that the segment installation meets qualified quality requirements, which indirectly increases the cost of construction. Conventional segment installation and adjustment requires the cooperation of two or more people, and if there is still a misalignment problem after installation, it may lead to the segment installation in the tunnel being not densely spliced, and there is a risk of water leakage in the later stage. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the utility model are described in detail below.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0034] Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, this embodiment provides a tunnel segment assembly, including a first segment 1, a second segment 2 and a positioning member 3. Among them, the first segment 1 and the second segment 2 are both tunnel segments. When the shield machine completes a section and advances forward in the tunnel, the segments are installed to form a tunnel. When it is found that the two segments are not installed flush and there is a misalignment, the positioning member 3 can be installed to make the positions of the two segments flush. This tunnel segment assembly is mainly aimed at the installation of segments at the construction site in the tunnel. It is faced with whether the installation of the segments is flush and meets the construction requirements, to ensure that there is no misalignment in the installation of the segments after installation, and to ensure that water outside the tunnel does not leak into the tunnel segments.

[0035] Figure 2 yes Figure 1 The floor plan, such as Figure 2 As shown, in this embodiment, a first positioning sleeve 10 is provided at the concave end of the first segment 1, and the first positioning sleeve 10 is a hollow structure; a second positioning sleeve 20 is provided on the concave end of the second segment 2 near the first segment 1, and the second positioning sleeve is a hollow structure. In this embodiment, specifically, the cross-sections of the first positioning sleeve 10 and the second positioning sleeve 20 are hollow rectangular structures. Preferably, the first positioning sleeve 10 and the second positioning sleeve 20 are made of steel.

[0036] like Figure 3-Figure 5 As shown, the positioning member 3 extends from one side of the first positioning sleeve 10 or the second positioning sleeve 20 through the first positioning sleeve 10 or the second positioning sleeve 20 into the second positioning sleeve 20 or the first positioning sleeve 10 to align the first pipe segment 1 with the second pipe segment 2. In this embodiment, the width of the positioning member 3 is the same as the width of the first positioning sleeve 10 and the second positioning sleeve 20. When in use, after the positioning member 3 extends from one side of the first positioning sleeve 10 or the second positioning sleeve 20 into the first positioning sleeve 10 or the second positioning sleeve 20, the positioning member 3 is further knocked or hammered to further enter the second positioning sleeve 20. In this process, the first pipe segment 1 and the second pipe segment 2 with uneven seams can be effectively adjusted so that the first pipe segment 1 and the second pipe segment 2 are flush without any seams.

[0037] Specifically, in this embodiment, the positioning member 3 includes a wedge-shaped structure. Further, the longitudinal section of the positioning member 3 is set to be a right-angled trapezoid. So that the positioning member 3 can be more smoothly extended from one side of the first positioning sleeve 10 or the second positioning sleeve 20 into the interior thereof and connected to the second positioning sleeve 20 or the first positioning sleeve 10.

[0038] When in use, the positioning piece 3 can be arranged to extend from one side of the first pipe segment 1, that is, the positioning piece 3 passes through the first positioning sleeve 10 from one side of the first positioning sleeve 10, and the end of the positioning piece 3 can be hammered or knocked to make it further extend into the adjacent second positioning sleeve 20, so that the first pipe segment 1 and the second pipe segment 2 are flush with each other without any misalignment.

[0039] Similarly, the positioning piece 3 can also be arranged to extend from one side of the second pipe segment 2, that is, the positioning piece 3 passes through the second positioning sleeve 20 from one side of the second positioning sleeve 20, and the end of the positioning piece 3 can be hammered or knocked to make it further extend into the adjacent first positioning sleeve 10, so that the first pipe segment 1 and the second pipe segment 2 are flush and without misalignment.

[0040] This tunnel segment assembly includes a first segment 1, a second segment 2 and a positioning member 3. The positioning member 3 can be used to identify whether the first segment 1 and the second segment 2 are flush after installation, thereby ensuring the quality of the segment installation. During the construction process, if it is determined that the first segment 1 and the second segment 2 are not flush after installation, the positioning member 3 can be used to fine-tune the first segment 1 and the second segment 2 so that the two segments are installed in an aligned and flat manner by knocking or hammering. A single person can complete the adjustment construction independently, and the installation position of the segment can be determined at one time. There is no need to manually find the corresponding position many times, so that the position and height of the segment installation can meet the construction requirements, thereby improving the construction efficiency, having the advantages of convenient operation, saving manpower, saving costs, etc., and this tunnel segment assembly can also be promoted and applied to construction processes such as underground pipe corridors and underground pipelines, and has the characteristics of a wide range of applications and good operating effects.

[0041] As an optional embodiment, a first connection hole 100 is provided on the first pipe segment 1, and a second connection hole 200 is provided on the second pipe segment 2, and the first connection hole 100 and the second connection hole 200 are connected by bolts 300. During construction, after the mechanical equipment has installed the two pipe segments, the positioning member 3 is used to locate whether the installation positions of the two pipe segments are flush, and then the bolts 300 are inserted into the first connection hole 100 and the second connection hole 200 to fix the two pipe segments.

[0042] Specifically, Figure 1 and Figure 2As shown, the first connection holes 100 are arranged to include multiple groups, and the multiple groups of first connection holes 100 are arranged to be at least three groups evenly arranged along the length direction of the first tube segment 1; at least two groups are evenly arranged along the width direction of the first tube segment 1, so that when the first tube segment 1 is connected to the second tube segment 2, the force is more uniform and the connection stability is better. In this embodiment, the first connection holes 100 are arranged to extend along the concave surface of the first tube segment 1 to the end surface of the first tube segment 1, and are used to connect with the second tube segment 2.

[0043] The second connection holes 200 on the second pipe segment 2 are arranged in one-to-one correspondence with the first connection holes 100 on the first pipe segment 1, that is, the second connection holes 200 include multiple groups, and the multiple groups of second connection holes 200 are arranged to be at least three groups evenly arranged along the length direction of the second pipe segment 2; and at least two groups are evenly arranged along the width direction of the second pipe segment 2.

[0044] As an optional embodiment, a first fixed tube hole 11 is further provided on the first tube segment 1, the first fixed tube hole 11 includes at least one, and the first fixed tube hole 11 is a through hole penetrating the concave surface and the convex surface of the first tube segment 1; a second fixed tube hole 21 is further provided on the second tube segment 2, the second fixed tube hole 21 is provided in a one-to-one correspondence with the first fixed tube hole 11, and the second fixed tube hole 21 is a through hole penetrating the concave surface and the convex surface of the second tube segment 2.

[0045] The first fixed pipe hole 11 and the second fixed pipe hole 21 are used for lifting and transporting the pipe segment. When in use, the pipe segment lifting and transporting machine fixes the first pipe segment 1 and the second pipe segment 2 through the first fixed pipe hole 11 and the second fixed pipe hole 21, and then rotates or lifts the pipe segment through mechanical equipment to place the pipe segment at the initial position to be installed.

[0046] A method for adjusting a tunnel segment as described above comprises the following steps:

[0047] S1: transporting the first pipe segment 1 and the second pipe segment 2 to the position where the pipe segments are to be installed for preliminary installation;

[0048] Specifically, in this embodiment, a segment conveyor is used to fix the first segment 1 by inserting a fixing rod into the first fixing pipe hole 11, and a manual operation machine is used to lift and transport the first segment 1 to the segment position to be installed for preliminary installation of the segment. Similarly, a segment conveyor is used to fix the second segment 2 by inserting a fixing rod into the second fixing pipe hole 21, and a manual operation machine is used to lift and transport the second segment 2 to the segment position to be installed for preliminary installation of the segment.

[0049] S2: Determine whether the first positioning sleeve 10 on the first pipe segment 1 is flush with the second positioning sleeve 20 on the second pipe segment 2;

[0050] Specifically: after the segment conveyor transports the segment to the initial position where it needs to be installed, slowly adjust the segment conveyor, and judge whether the segment is installed flat and without misalignment by observing whether the first positioning sleeve 10 and the second positioning sleeve 20 pre-embedded on the two segments are aligned.

[0051] S3: If the judgment result is no, that is, when the first positioning sleeve 10 on the first pipe segment 1 and the second positioning sleeve 20 on the second pipe segment 2 are not aligned and there is a misalignment of the pipe segments, the positioning member 3 is inserted into the first positioning sleeve 10, and force is applied to the positioning member 3 to make it enter the second positioning sleeve 20, so as to drive the first pipe segment 1 and the second pipe segment 2 to be adjusted to be flush with each other without misalignment; or the positioning member 3 is inserted into the second positioning sleeve 20, and force is applied to the positioning member 3 to make it enter the first positioning sleeve 10, so as to drive the first pipe segment 1 and the second pipe segment 2 to be adjusted to be flush with each other without misalignment;

[0052] If the judgment result is yes, the first connection hole 100 on the first pipe segment 1 and the second connection hole 200 on the second pipe segment 2 are connected by bolts 300 and fixed by nuts.

[0053] S4: Connecting the first tube segment 1 and the second tube segment 2, specifically by connecting the first connection hole 100 on the first tube segment 1 and the second connection hole 200 on the second tube segment 2 by bolts 300, and fixing them by nuts.

[0054] S5: Remove the positioning member 3 and complete the construction. The positioning member 3 can be reused many times, which is green and environmentally friendly and truly saves construction costs.

[0055] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
