Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, and in particular to a small-section tunnel lining maintenance device. Background Technology

[0002] Most existing tunnels are highway tunnels or railway tunnels, which need to accommodate the passage of vehicles or trains. Therefore, the cross-section of the tunnels is relatively large. For the construction of these large-section tunnels, the volume of the secondary lining is large, and the curing of the secondary lining is mostly carried out by spraying water directly onto the concrete surface.

[0003] However, in some water diversion projects or oil and gas pipeline projects, it is not necessary to set up a large tunnel cross section. For small cross-section tunnels with cross-sectional width and height dimensions less than or equal to 3m and 3.5m respectively, the secondary lining volume is small and the space inside the tunnel is limited, making it difficult to arrange a large number of spray pipes and water trucks to directly spray the concrete surface for curing. Utility Model Content

[0004] The purpose of this invention is to provide a curing device for the lining of small-section tunnels, which addresses the problem that existing technologies make it difficult to arrange a large number of spray pipes and water trucks to directly spray water onto the concrete surface for curing in small-section tunnels where space is limited.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A small-section tunnel lining maintenance device includes a water pipe. The width of the tunnel cross-section is less than or equal to 3m, and the height of the tunnel cross-section is less than or equal to 3.5m. The water pipe is connected to the top of the tunnel cross-section. Several nozzles are spaced along the length of the tunnel. The nozzles spray water into the tunnel space to increase the air humidity, thereby indirectly maintaining the lining by utilizing the air humidity.

[0006] The small-section tunnel lining curing device described in this utility model benefits from the limited space of small-section tunnels, which makes it easy to maintain air humidity. It uses humid air instead of direct spraying to cure the lining concrete of small-section tunnels, which simplifies the layout and structure of the water pipes and saves costs.

[0007] As a preferred technical solution of this utility model, the water pipe is connected to the middle position of the top of the tunnel.

[0008] As a preferred technical solution of this utility model, the nozzles are respectively provided along the bottom and both sides of the water pipe ring.

[0009] As a further preferred technical solution of this utility model, along the length of the tunnel, three adjacent nozzles are respectively located at the bottom of the water pipe, the right side of the water pipe, and the left side of the water pipe.

[0010] As a preferred technical solution of this utility model, the nozzle is provided with an atomizing structure.

[0011] As a preferred technical solution of this utility model, the water pipe is made of PVC pipe, PE pipe, PPR pipe, galvanized steel pipe, stainless steel pipe or rubber hose.

[0012] As a preferred technical solution of this utility model, a plurality of connecting components are provided at intervals along the length of the tunnel. The connecting components are connected to the lining and support the water pipe.

[0013] As a further preferred technical solution of this utility model, the connecting component includes a U-shaped pipe support and an ear plate. The ear plate is connected to both sides of the opening of the U-shaped pipe support, the water pipe is arranged in the opening area of ​​the U-shaped pipe support, and the ear plate is connected to the lining.

[0014] As a further preferred technical solution of this utility model, the ear plate is provided with a through hole, and a pre-embedded bolt is provided in the lining. The ear plate passes through the pre-embedded bolt and is fastened by a nut.

[0015] As a further preferred technical solution of this utility model, the connecting component adopts a metal structure.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The present invention provides a small-section tunnel lining curing device that, due to the limited space of small-section tunnels, makes it easy to maintain air humidity. By using humid air instead of direct spraying for the curing of the lining concrete of small-section tunnels, the arrangement and structure of the water pipes are simplified, thus saving costs.

[0019] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter 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.

[0020] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is 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 typically 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, 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.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, 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%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0022] 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.

[0023] 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.

[0024] 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," "equipped 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.

[0025] In related technologies, due to the limited space in small-section tunnels, it is not easy to arrange a large number of spray pipes and water trucks to directly spray water onto the concrete surface for curing during secondary lining. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 3 To elaborate.

[0026] Example 1 like Figures 1 to 3 As shown, the present invention provides a small-section tunnel lining maintenance device, which includes a water pipe 1. The width of the tunnel section is less than or equal to 3m, and the height of the tunnel section is less than or equal to 3.5m. The water pipe 1 is connected to the top of the tunnel section, and preferably the water pipe 1 is connected to the middle position of the top of the tunnel.

[0027] like Figure 3 As shown, the water pipe 1 is provided with a plurality of nozzles 11 spaced apart along the length of the tunnel; as Figure 2 As shown, nozzles 11 are respectively provided along the bottom and both sides of the annular water pipe 1; Figure 3 As shown, along the length of the tunnel, three adjacent nozzles 11 are respectively located at the bottom, right and left sides of the water pipe 1. This method can avoid the situation where a large number of nozzles 11 in a local location along the length of the water pipe 1 causes local space of the tunnel to be wet while other spaces are relatively dry. In other words, it can more effectively ensure the overall humidity of the small cross-section tunnel.

[0028] The nozzle 11 sprays water into the tunnel space to increase air humidity, and uses the air humidity to indirectly cure the lining 01.

[0029] In an optional embodiment, the nozzle 11 is provided with an atomizing structure, which sprays finer water droplets that can be suspended in the air, ensuring that the tunnel ceiling can also be well moisturized.

[0030] In one optional embodiment, the water pipe 1 is made of PVC pipe, PE pipe, PPR pipe, galvanized steel pipe, stainless steel pipe or rubber hose.

[0031] like Figure 2 and Figure 3As shown, several connecting components are spaced apart along the length of the tunnel. The connecting components are connected to the lining 01 and support the water pipe 1. The connecting components include a U-shaped pipe support 21 and a lug plate 22. The lug plate 22 is connected to both sides of the opening of the U-shaped pipe support 21. The water pipe 1 is arranged in the opening area of ​​the U-shaped pipe support 21. The lug plate 22 is connected to the lining 01 and has a through hole. The lining 01 is provided with a pre-embedded bolt 31. The lug plate 22 passes through the pre-embedded bolt 31 and is fastened by a nut 32.

[0032] In an alternative implementation, the connecting component is a metal structure.

[0033] The small-section tunnel lining curing device described in this embodiment benefits from the limited space of the small-section tunnel, which makes it easy to keep the air humid. It uses humid air instead of direct spraying to cure the concrete lining of the small-section tunnel, which simplifies the layout and structural form of the water pipe 1 and saves costs.

[0034] 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.
