Description
Technical Field
[0001] This utility model relates to the technical field of underground engineering construction, and in particular to a system for constructing the side walls of underground stations. Background Technology
[0002] The construction of underground railway stations generally follows the open-cut method: after the excavation and support of the foundation pit are completed, the foundation slab and main slab are poured first, and then the side walls and roof slab are constructed section by section upwards. The side walls, as the core retaining and load-bearing structures, require special attention to ensure their quality. During construction, the vertical main reinforcement and horizontal distribution reinforcement are first positioned, double-sided formwork is erected and fixed with tie bolts, and then impermeable concrete is poured in layers. Among these construction steps, the concrete curing process is particularly critical. Because the vertical surfaces of the side walls are difficult to cover for moisture retention, dedicated personnel must be arranged to manually water the walls 24 hours a day. Workers use handheld sprayers or hoses to evenly spray the walls every 1-2 hours, especially keeping the surface continuously moist after the formwork is removed, so that the concrete remains moist in the high-temperature environment, preventing plastic cracks caused by excessive evaporation of moisture.
[0003] However, when constructing underground stations, it is necessary to install full-span scaffolding inside the underground station's cavity space. This makes it difficult to manually water and cure the side wall concrete, thus affecting the quality of the side wall concrete. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies in the construction of underground stations, which require the installation of full-span scaffolding inside the cavity space of the underground station, making it inconvenient for manual watering and curing of the side wall concrete and affecting the quality of the side wall concrete. This invention provides a system for constructing the side walls of underground stations.
[0005] This utility model provides a system for constructing the side walls of underground stations, comprising: Side wall formwork; A limiting member is provided on the side of the side wall formwork. The limiting member is connected to the side wall formwork and the vertical main reinforcement on both sides. The axis of the vertical main reinforcement is parallel to the plane of the side wall formwork. The limiting member is used to limit the distance from the vertical main reinforcement to the side wall formwork. A spraying component is connected to the vertical main reinforcement, and the position of the spraying component is higher than the top surface of the side wall formwork.
[0006] The dimensions of the limiting components are determined based on the thickness of the concrete cover of the reinforcing bars. Limiting components are installed on the sides of the sidewall formwork, with each component connected to both the sidewall formwork and the vertical main reinforcement bars. This ensures the maximum possible thickness of the concrete cover for the vertical main reinforcement bars, thus improving the structural stability of the underground station's sidewalls. The spray system is positioned above the top surface of the sidewall formwork, ensuring that the poured concrete remains within its spray range. Since the spray system is connected to the vertical main reinforcement bars, manual watering is unnecessary, and this connection does not interfere with the installation of the full-span scaffolding inside the cavity. Furthermore, the cavity can be cooled by the spray system, which is beneficial for the curing of the underground station.
[0007] Preferably, the spraying component includes a water supply pipe connected to the vertical main reinforcement, and the water supply pipe has multiple water outlets spaced apart along the length of the side wall formwork.
[0008] The water supply pipe is equipped with multiple outlets at intervals along its length, which can maximize the spraying range and help improve the quality of the side walls of the underground station.
[0009] Preferably, the orientation of the water outlet is adjustable.
[0010] Adjusting the orientation of the water outlet can maximize the spray range and improve the quality of the underground station's side walls.
[0011] Preferably, the water supply pipe is equipped with a lifting ring, and the lifting ring is connected to a pull rope, which is pulled to adjust the orientation of the water outlet.
[0012] The orientation of the water outlet can be adjusted by setting a lifting ring and a pull rope. The structure is simple and easy to operate.
[0013] Preferably, the water outlet is connected to an external shower head.
[0014] Connecting a shower head to the water outlet can expand the spray range.
[0015] Preferably, the spraying component is detachably connected to the vertical main rib.
[0016] The sprinkler components can be detachably connected to the vertical main reinforcement, and the position and height of the sprinkler components can be adjusted as needed, which helps to improve the concrete pouring quality of the underground station side walls.
[0017] Preferably, the limiting member is detachably connected to the top of the side of the side wall template.
[0018] Because the limiting component is not located inside the poured concrete, it can be detachably installed on the top surface of the side wall formwork, which helps to improve the quality of the underground station side wall.
[0019] Preferably, the limiting member is connected to the side wall template by bolts or reinforcing bars.
[0020] Preferably, the limiting member is a square tube.
[0021] Using a square tube for the limiting component can minimize its displacement while reducing its own weight. The square tube shape also facilitates fixing the limiting component.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a system for constructing the side walls of underground stations, including side wall formwork, limiting components, and a spraying component. The limiting component is installed on the side of the side wall formwork, with its two sides connected to the side wall formwork and vertical main reinforcement bars respectively. This ensures the protective layer thickness of the vertical main reinforcement bars as much as possible, thus improving the structural stability of the underground station's side walls. The spraying component is positioned above the top surface of the side wall formwork, ensuring that the poured concrete remains within the spraying range of the component. Since the spraying component is connected to the vertical main reinforcement bars, manual watering is unnecessary, and it does not affect the installation of the full-span scaffolding inside the cavity. Furthermore, the cavity can be cooled by the spraying device, which is beneficial for the curing of the underground station. This application overcomes the shortcomings of existing technologies where the construction of underground stations requires the installation of full-span scaffolding inside the cavity space, making manual watering of the side wall concrete inconvenient and affecting its quality.

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.
[0025] 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.
[0026] 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.

[0028] 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.
[0029] 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.
[0030] Example 1 like Figures 1 to 2 As shown, a system for constructing the sidewalls of an underground station includes: Side wall formwork 1; Limiting member 2 is disposed on the side of the side wall formwork 1. The two sides of the limiting member 2 are respectively connected to the side wall formwork 1 and the vertical main reinforcement 4. The axis of the vertical main reinforcement 4 is parallel to the plane of the side wall formwork 1. The limiting member 2 is used to limit the distance from the vertical main reinforcement 4 to the side wall formwork 1. A spraying component is connected to the vertical main reinforcement 4, and the position of the spraying component is higher than the top surface of the side wall formwork 1.
[0031] The dimensions of the limiting component 2 are determined based on the thickness of the concrete cover of the reinforcing steel. The limiting component 2 is installed on the side of the side wall formwork 1, and its two sides are connected to the side wall formwork 1 and the vertical main reinforcement 4, respectively. This ensures the maximum thickness of the concrete cover for the vertical main reinforcement 4, thus improving the structural stability of the underground station's side walls. The spraying component is positioned higher than the top surface of the side wall formwork 1, ensuring that the poured concrete remains within its spraying range. Since the spraying component is connected to the vertical main reinforcement 4, manual watering is unnecessary, and this connection does not affect the installation of the full-span scaffolding inside the cavity. Furthermore, the cavity can be cooled by the spraying device, which is beneficial for the curing of the underground station.
[0032] The dimensions of the limiting component 2 are determined based on the thickness of the concrete cover of the reinforcing steel. The limiting component 2 is installed on the top surface of the side wall formwork 1, with both sides of the limiting component 2 connected to the side wall formwork 1 and the vertical main reinforcement 4, thus maximizing the thickness of the concrete cover of the vertical main reinforcement 4 and improving the structural stability of the underground station's side walls. The spraying component is positioned higher than the limiting component 2, ensuring that the poured concrete remains within the spraying range of the spraying component. Since the spraying component is connected to the vertical main reinforcement 4, manual watering is unnecessary, and it does not affect the installation of the full-span scaffolding inside the cavity. Furthermore, the cavity can be cooled by the spraying device, which is beneficial for the curing of the underground station.
[0033] Furthermore, such as Figure 1 As shown, the spraying component includes a water supply pipe 301 ( Figure 2 (Not shown), the water supply pipe 301 is connected to the vertical main reinforcement 4, and the water supply pipe 301 has multiple water outlets spaced apart along the length of the side wall formwork 1. The multiple water outlets spaced apart along the length of the water supply pipe 301 can maximize the spraying range and help improve the quality of the underground station side wall.
[0034] Furthermore, the orientation of the water outlet can be adjusted. Adjusting the orientation of the water outlet can maximize the spraying range, which is beneficial for improving the quality of the side walls of the underground station.
[0035] Furthermore, the water supply pipe 301 is equipped with a lifting ring 303 ( Figure 2 (Not shown), the lifting ring 303 is connected to a pull rope 6 ( Figure 2 (Not shown), the direction of the water outlet is adjusted by pulling the pull rope 6. The direction of the water outlet can be adjusted by setting the lifting ring 303 and the pull rope 6, which is simple in structure and easy to operate.
[0036] Furthermore, such as Figure 1 As shown, the water outlet is connected to a shower head 302 ( Figure 2 (Not shown), which helps to expand the spraying range.
[0037] Furthermore, the spraying component is detachably connected to the vertical main reinforcement 4. In this embodiment, the water supply pipe 301 is tied to the vertical main reinforcement 4, and the position and height of the spraying component can be adjusted as needed, which is beneficial to improving the concrete pouring quality of the underground station side wall.
[0038] Furthermore, the limiting member 2 is detachably connected to the top of the side of the side wall formwork 1. Because the limiting member 2 is not located inside the poured concrete, it can be detachably installed on the top of the side of the side wall formwork 1, which helps to improve the quality of the underground station side wall. In this embodiment, the limiting member 2 is connected to the side wall formwork 1 by bolts or by reinforcing bars.
[0039] Furthermore, the limiting member 2 is a square tube, which can reduce the weight of the limiting member 2 while minimizing its displacement. The square tube form of the limiting member 2 also facilitates fixation.
[0040] The above content 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.
