Description

Technical Field

[0001] This utility model relates to the field of underwater tunnel ventilation, and in particular to an underwater tunnel flue plate. Background Technology

[0002] In the construction practice of flue slab systems for submarine tunnels, it is usually necessary to disassemble the integral flue slab into multiple unit panels for manufacturing and installation. However, this disassembly method places high demands on the alignment accuracy and joint treatment between the unit panels. In actual operation, if the splicing control between unit panels is not properly implemented, problems such as excessively large installation gaps or inability to smoothly splice the unit panels can easily occur. This not only affects the overall sealing and safety of the flue structure but also poses potential hazards for later operation and maintenance. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a flue plate for a submarine tunnel.

[0004] A flue panel for an underwater tunnel is installed on the tunnel's support frame and is assembled from multiple flue unit panels. Each flue unit panel has an arc-shaped protrusion on its first side and an arc-shaped groove on its second side. The protrusion of one flue unit panel can be inserted into the groove of another flue unit panel. Each flue unit panel has at least one notch on its second side. The notches of two adjacent flue unit panels are joined together to form a groove, which is filled with sealant.

[0005] Preferably, each of the flue unit plates has a first notch and a second notch on its second side, and the opening directions of the first notch and the second notch are opposite.

[0006] Preferably, a rubber plate is provided at the connection between the flue unit plate and the bracket.

[0007] Preferably, the connection between the flue unit plate and the bracket is filled with sealant.

[0008] Preferably, the flue unit plate has a pre-embedded lifting ring.

[0009] Preferably, the flue unit plate is provided with a pre-embedded steel plate, which is used to mount the fan.

[0010] Preferably, multiple pre-embedded steel plates are spaced apart in the middle of the flue unit plate.

[0011] Preferably, the flue unit plate is provided with a smoke exhaust port.

[0012] Preferably, the outer periphery of the smoke exhaust port is provided with a pre-embedded part, which is used to install the fan assembly.

[0013] Preferably, the embedded part includes a first embedded part and a second embedded part. The first embedded part is disposed on the short side of the smoke exhaust port, and the second embedded part is disposed on the long side of the smoke exhaust port. The first embedded part and the second embedded part are welded at the connection point. Both the first embedded part and the second embedded part are provided with bolt holes for installing a fan.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a flue plate for an underwater tunnel. By directly installing the flue plate onto the tunnel's corbel, the installation of the flue plate is convenient. The interlocking of the arc-shaped protrusions and arc-shaped grooves improves the docking accuracy between the unit plates. The notches of two adjacent flue plate units are spliced ​​together to form a groove, which can be filled with sealant to facilitate joint treatment.

[0015] This invention can avoid the problems of excessive installation gaps or inability to smoothly splice unit panels, thereby improving the overall sealing and safety of the flue structure. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0034] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2mm-1mm, preferably within 0.2mm-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0036] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0037] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0038] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0039] Example 1 like Figures 1-3As shown, a flue slab 3 for a submarine tunnel is installed on the corbels 2 of the secondary lining 1 of the tunnel. Two rows of corbels 2 are symmetrically arranged along the tunnel centerline. The flue slab 3 is assembled from multiple flue unit plates 31, each of which is an arc-shaped plate resting on top of the two rows of corbels 2. In an optional embodiment, a rubber plate 4 is provided at the connection between the flue unit plate 31 and the corbel 2 to improve the stability of placement and reduce displacement of the flue unit plate 31. Furthermore, sealant 5 is injected at the connection between the flue unit plate 31 and the corbel 2 to achieve a stable connection and seal between the flue unit plate 31 and the corbel 2.

[0040] like Figures 4-6 As shown, each flue unit plate 31 has an arc-shaped protrusion 311 on its first side and an arc-shaped groove 312 on its second side. The first and second sides are arranged opposite to each other. The protrusion 311 of one flue unit plate 31 can be inserted into the groove 312 of another adjacent flue unit plate 31, so as to achieve precise docking of two adjacent flue unit plates 31.

[0041] like Figures 7-11 As shown, each of the flue unit plates 31 has at least one notch on its second side. The notches of two adjacent flue unit plates 31 are joined together to form a groove, and the groove is filled with sealant 5. By joining the notches of two adjacent flue unit plates 31 together to form a groove, sealant 5 can be filled into the groove, which facilitates joint treatment.

[0042] In an optional embodiment, each of the flue unit plates 31 is provided with a first notch 313 and a second notch 314 on its second side. The opening directions of the first notch 313 and the second notch 314 are opposite, thereby forming two slots. The sealant 5 can be injected into the slots from two opposing directions at the same time, which is more conducive to joint treatment and improves the connection stability and sealing of two adjacent flue unit plates 31.

[0043] Furthermore, the first notch 313 and the second notch 314 can be arranged symmetrically.

[0044] Furthermore, the first notch 313 and the second notch 314 can be asymmetrically arranged, for example, as shown in the figure. Figures 7-8 As shown, the opening depth of the first notch 313 is greater than the opening depth of the second notch 314, but the opening slope of the first notch 313 is less than the opening slope of the second notch 314. In this way, an asymmetrical groove structure can be formed, which is more conducive to joint treatment and improves the connection stability and sealing of the two adjacent flue unit plates 31.

[0045] Specifically, after the flue plate 3 is installed, the joint sealing construction is carried out. The sealing material is fireproof sealant, which is required to be filled tightly. Before the joint is sealed, the gap is cleaned with high-pressure gas. If necessary, it is rinsed with high-pressure water and dried. Then, a high-altitude work vehicle is used to seal the joint from one end to the other. The sealant nozzle is cut according to the actual joint width. Usually, the sealant outlet is slightly smaller than the joint width. The sealant should be applied evenly, and there should be no gaps or leakage. The front end of the sealant nozzle should be close to the bottom of the joint to apply the sealant, so that the sealant is naturally squeezed outward from the bottom, and the sealant is ensured to adhere firmly to both sides of the joint.

[0046] In an optional embodiment, the flue unit plate 31 is pre-embedded with lifting rings 6, and the number of lifting rings 6 is at least three. The lifting rings 6 are symmetrically arranged in the middle of the flue unit plate 31, so as to facilitate the lifting of the flue unit plate 31 by a crane and its installation on the tunnel bracket 2.

[0047] In an optional embodiment, the flue unit plate 31 is a reinforced concrete slab. The concrete is of C45 strength grade and contains polypropylene coarse fiber. Its mix design must meet the requirements of strength, durability, and workability. Due to the corrosiveness of the marine environment, the impermeability and crack resistance of the concrete must be given special consideration. The components such as cement, aggregate, and admixtures must be selected reasonably in the mix design.

[0048] Example 2 Based on Embodiment 1, this embodiment provides a flue unit plate 31 that can be used to mount a fan, which makes it easier to mount the fan and facilitates ventilation in the submarine tunnel.

[0049] like Figure 4 As shown, the flue unit plate 31 is provided with a pre-embedded steel plate 7, which is used to mount the fan. Multiple pre-embedded steel plates 7 are spaced apart in the middle of the flue unit plate 31. The pre-embedded steel plate 7 can be made of 316 stainless steel.

[0050] The embedded steel plates 7 are of two types, A and B, using 20mm thick 316 stainless steel. Type A measures 300*400*20mm, and Type B measures 2200*300*20mm. The embedded steel plates 7 are positioned longitudinally and transversely according to the design dimensions in the drawings. They are first tied and fixed to the bottom of the reinforcing cage. After the reinforcing cage is placed in the formwork, the embedded parts are finely adjusted and welded securely. After the reinforcing bars and embedded steel plates 7 are installed, a self-inspection is performed. Only after all procedures pass inspection can the next procedure proceed.

[0051] Example 3 Based on Embodiment 1, this embodiment provides a flue unit plate 31 with a smoke exhaust port 8, which is suitable for the flue structure at the electric smoke exhaust port of the drill-and-blast tunnel, thus making it easier to install fans and improve ventilation in the submarine tunnel.

[0052] like Figures 12-16 As shown, the flue unit plate 31 is provided with a smoke exhaust port 8. An embedded part is provided on the outer periphery of the smoke exhaust port 8, which is used to install the fan assembly.

[0053] The embedded parts include a first embedded part 9 and a second embedded part 10. The first embedded part 9 is disposed on the short side of the smoke exhaust port 8, and the second embedded part 10 is disposed on the long side of the smoke exhaust port 8. The first embedded part 9 and the second embedded part 10 are welded at the connection to ensure a seal. The first embedded part 9 and the second embedded part 10 form a box-shaped structure.

[0054] Both the first embedded part 9 and the second embedded part 10 are provided with bolt holes 11, which are used to install the fan.

[0055] Both the first embedded part 9 and the second embedded part 10 include a horizontal steel plate and a vertical steel plate. The bottom surface of the horizontal steel plate is lower than the bottom surface 12 of the flue plate, and the bolt hole 11 is opened in the horizontal steel plate.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
