Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to the support structure for cut-and-cover railway stations that pass under existing tracks. Background Technology

[0002] With social development, in order to meet the needs of people's livelihood and the economy, more and more subway lines have been built underground in cities. Moreover, it is common to see new subway lines being built under existing subway sites, and stations being dug on top of existing lines.

[0003] When constructing an open-cut railway station, the foundation pit is typically excavated vertically, with multiple layers of vertical support installed following a "support first, excavate later" approach. The first layer of concrete support is usually installed at the top of the pit. Then, as the pit is excavated deeper, steel supports are used between the lining walls on both sides of the pit for reinforcement. The concrete supports typically include longitudinal and transverse beams installed within the lining. Multiple longitudinal beams are connected to two transverse beams at each end. To ensure the strength of the concrete supports, the spacing and number of transverse beams are calculated based on parameters such as the length and width of the pit, ensuring stable support for the pit. However, during implementation, as the pit is excavated, construction equipment or materials need to be moved in or out of the pit. Therefore, the spacing between multiple longitudinal beams can be large, potentially leading to insufficient strength of the concrete supports.

[0004] In existing technologies, such as the detachable support structure for a subway open-cut station described in patent application number CN202322219741.6, multiple longitudinal beams and support rods are provided between the crossbeams on both sides of the concrete support. The support rods mainly consist of threaded rods and hexagonal socket sleeves at both ends. The threaded rods and hexagonal socket sleeves are connected by threads, and disassembly is achieved by tightening the threaded rods. This ensures that while the support rods stably support the concrete support, they can also be disassembled to create space for the entry of subsequent equipment and materials. However, some problems still exist in its use and need improvement:

[0005] When equipment and materials are brought in and out, multiple support rods need to be disassembled, which takes a lot of time. If it is necessary to reduce the disassembly and installation time, multiple construction workers need to disassemble multiple support rods at the same time, which consumes a lot of manpower.

[0006] When dismantling the support rods, personnel need to be on the support rods to dismantle them, or equipment such as crane platforms need to be used to move personnel to the support rods for dismantling. This makes the dismantling of the support rods a safety hazard, and it also requires the use of cranes and other lifting equipment to lift the support rods, making the overall process slow.

[0007] Therefore, there is an urgent need for a support structure that can stably support concrete supports without hindering the entry and exit of equipment and materials. Utility Model Content

[0008] The purpose of this utility model is to provide a support structure for cut-and-cover stations that pass under existing tracks, in order to solve the above-mentioned technical problems.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A support structure for an open-cut railway station passing under an existing track includes two crossbeams, respectively installed on the walls on both sides and arranged opposite each other. Multiple longitudinal beams are spaced apart between the two crossbeams. Multiple shells, each with a groove adapted to fit the crossbeam, are detachably installed on the two crossbeams. The inner walls of the grooves on three sides of each shell abut and fit against the outer walls on three sides of each crossbeam. A fixed end is located on the lower side of each shell, positioned on the wall surface. A take-up end is located on the upper side of each shell, positioned on the ground on one side of the pit opening. A support rope is installed between the take-up end and the fixed end, with both ends connected to the take-up end and the fixed end respectively. A portion of the support rope abuts against the side of the shell facing the other wall.

[0011] In some embodiments, a first support column is provided on the side of the housing facing the other wall, and a first groove adapted to the support rope is provided at one end of the first support column facing the other wall. When the support rope abuts against the housing, the rope body of the support rope abutting against the housing is disposed in the first groove.

[0012] In some embodiments, the distance between the end of the fixed end facing another wall and the wall is less than the distance between the first groove on the upper side of the fixed end and the wall.

[0013] In some embodiments, the wall is perpendicular to the horizontal ground above it, and the first cable groove is located in a plane perpendicular to the wall and the horizontal ground. When the support rope is installed in the first cable groove, the support rope is located in the plane.

[0014] In some embodiments, the end of the first support column facing the other wall is a hemispherical structure with the spherical surface facing the other wall, the first groove is opened along the spherical surface of the first support column, and the circumferential side of the first support column is perpendicular to the side of the shell facing the other wall.

[0015] In some embodiments, a second support column is provided on both the upper and lower sides of the first support column. The two second support columns are symmetrically arranged relative to the first support column, and the end of each column facing the other wall adopts a hemispherical structure with the spherical surface facing the other wall. The distance between the spherical end of the second support column and the other wall is less than the distance between the spherical end of the first support column and the other wall, and greater than the distance between the fixed end and the other wall.

[0016] In some embodiments, the second support column is provided with a second groove opened along the spherical surface, and the second groove is located in a plane that is perpendicular to both the wall and the horizontal ground.

[0017] In some embodiments, the end faces of the upper and lower sidewalls of the groove away from the inner sidewall of the groove are both arc-shaped, and the arc faces of the end faces of the upper and lower sidewalls of the groove face each other.

[0018] In some embodiments, a triangular support is provided on the upper side of the housing, the triangular support is disposed on the upper side of the crown beam, and the side of the triangular support is connected to the wall on the upper side of the crown beam. A fixed pulley is provided at the other end of the triangular support away from the wall. The fixed pulley is provided with a third groove, and the third groove is opened along the circumferential outer wall of the fixed pulley. A portion of the support rope is disposed in the third groove and abuts against a portion of the inner sidewall of the third groove.

[0019] In some embodiments, the fixed end includes two triangular plates disposed opposite to each other, a connecting block is provided between the triangular plates, a rope groove is provided on one side of the connecting block, the rope groove passes through the connecting plate, and the groove between the two ends of the rope groove is provided on the side of the connecting block, and a limiting end is provided at one end of the support rope. When one end of the support rope is provided in the rope groove, the limiting end abuts against the side of the connecting block where the groove at one end of the rope groove is located.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] The grooves in the shell protect and support the circumferential outer wall of the crossbeam. At the same time, the support rope abuts against the shell, thus providing force for the shell to support the crossbeam. Then, the fixed end and the take-up end are connected to the two ends of the support rope, thus providing force for the support rope. This allows the support rope to stably abut against the shell and apply force to the shell, making the shell's support for the crossbeam relatively stable and preventing a large space from being left between the two crossbeams, making it easier for subsequent materials and equipment to enter and exit.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0052] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0053] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0054] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0056] It should be understood that during the excavation of the foundation pit, the concrete support may need to be supported by support rods due to strength requirements. However, when equipment and materials are moved in and out, multiple support rods need to be disassembled, which takes a lot of time. If it is necessary to reduce the disassembly and installation time, multiple construction workers need to disassemble multiple support rods at the same time, which consumes a lot of manpower.

[0057] Meanwhile, when dismantling the support rods, personnel need to be on the support rods to dismantle them, or equipment such as crane platforms need to be used to move personnel to the support rods for dismantling. This makes the dismantling of the support rods a safety hazard, and it also requires the use of cranes and other lifting equipment to lift the support rods, making the overall process slow.

[0058] To address the aforementioned issues, this embodiment provides a support structure for cut-and-cover stations that pass under existing tracks, primarily comprising multiple two-beam structures 1 and multiple shell structures 4. This structure is mainly used when concrete supports reinforce the wall 2, enhancing the strength of the concrete support without hindering the entry and exit of materials and equipment. Furthermore, it is relatively easy to disassemble and install, and poses lower safety risks.

[0059] like Figures 1-2 As shown, two crossbeams 1 are respectively set on the two side walls 2 and are arranged opposite each other. The crossbeams 1 adopt a rectangular structure. The two walls 2 are parallel to each other and the wall 2 is provided with a cap beam 9. In this embodiment, multiple longitudinal beams 3 are provided between the two crossbeams 1 and are parallel to the two crossbeams 1. The multiple longitudinal beams 3 are spaced apart along the extension direction of the crossbeams 1. In order to improve the strength, a reinforcing beam 20 is provided between adjacent longitudinal beams 3 to improve the strength of the concrete support.

[0060] In this embodiment, as Figures 1-6As shown, it also includes multiple shells 4, wherein the shell 4 is provided with a groove 41 adapted to the crossbeam 1. Specifically, the shell 4 adopts a rectangular structure, and one side is recessed inward to form a groove 41. The groove 41 is adapted to the size and shape of the crossbeam 1, so that the upper and lower sides of the crossbeam 1 and the side facing the other wall 2 respectively abut and fit against the three inner walls of the groove 41, thereby supporting the crossbeam 1 and ensuring the strength of the crossbeam 1. When the concrete support is carried out, the groove 41 of the shell 4 is moved towards the crossbeam 1 and towards the crossbeam 1, so that part of the crossbeam 1 is inserted into the groove 41 and abuts and fits against the inner wall of the groove 41, thereby supporting the crossbeam 1.

[0061] The inner walls of the upper and lower sides of the groove 41 can have a small gap with the crossbeam 1, thereby ensuring that part of the crossbeam 1 is inserted into the groove 41 and abuts against and fits against the inner wall of the groove 41.

[0062] In this embodiment, multiple shells 4 can be spaced out according to stress analysis and usage requirements to ensure the strength of the concrete support. The support rope 7 can be made of cable, hemp rope, or other ropes, and can be selected according to the site environment, usage length, and quantity requirements.

[0063] In this embodiment, a fixed end 5 is provided on the lower side of the shell 4 and is located on the surface of the wall 2. A take-up end 6 is provided on the upper side of the shell 4 and is located on the ground on one side of the pit opening. A support rope 7 is provided between the take-up end 6 and the fixed end 5. The two ends of the support rope 7 are connected to the take-up end 6 and the fixed end 5 respectively. Part of the rope of the support rope 7 abuts against the side of the shell 4 facing the other wall 2. When the support rope 7 is tightened, the rope of the support rope 7 abutting against the shell 4 exerts a force on the shell 4, thereby abutting and tightening the shell 4 against the crossbeam 1, and providing stable support for the crossbeam 1.

[0064] The take-up end 6 can be a take-up device such as a winding reel or winding wheel.

[0065] In this embodiment, the groove 41 of the housing 4 protects and supports the circumferential outer wall of the crossbeam 1. At the same time, the support rope 7 abuts against the housing 4, thereby providing force for the support of the housing 4 on the crossbeam 1. Then, the fixed end 5 and the take-up end 6 are connected to the two ends of the support rope 7, thereby providing force for the support rope 7. This makes the support rope 7 stably abut against the housing 4 and apply force to the housing 4. As a result, the support of the housing 4 on the crossbeam 1 is relatively stable, and there is no large space left between the two crossbeams 1, which makes it easier for subsequent materials and equipment to enter and exit.

[0066] In some embodiments, such as Figures 1-6As shown, a first support column 42 is provided on the side of the shell 4 facing the other wall 2. The first support column 42 has a rectangular structure and is vertically arranged on the side of the shell 4. The end of the first support column 42 facing the other wall 2 is provided with a first groove 421, and the first groove 421 is adapted to the support rope 7, so that the rope of the support rope 7 can be placed in the first groove 421. In this embodiment, when the support rope 7 abuts against the shell 4, the part of the support rope 7 located on the shell 4 abuts against the inner wall of the first groove 421, so that the position of the support rope 7 abuts against the shell 4 is relatively stable, avoiding the position of the rope abutting against the shell 4 being unstable, thereby making the direction of the force of the rope on the shell 4 controllable and stable.

[0067] The first support column 42 is located at the center of the side of the shell 4 facing the other wall 2. Specifically, the center of the side of the shell 4 coincides with the center of the end face of the first support column 42 that contacts the shell 4, so that the force received by the shell 4 is more uniform and controllable.

[0068] In this embodiment, the distance between the end of the fixed end 5 facing the other wall 2 and the wall 2 is less than the distance between the first groove 421 on the upper side of the fixed end 5 and the wall 2. This results in more contact points between the support rope 7 and the first groove 421 on the shell 4 when the support rope 7 abuts against the shell 4, thus making the applied force more stable.

[0069] In some embodiments, such as Figures 1-4 As shown, the wall 2 is perpendicular to the horizontal ground above it, and the first groove 421 is located in a plane perpendicular to the wall 2 and the horizontal ground. The first groove 421 is located in this plane, so that when the support rope 7 is placed in the first groove 421, the support rope 7 is located in this plane. A triangular support 8 is provided on the upper side of the shell 4, and the triangular support 8 is located on the upper side of the crown beam 9. The side of the triangular support 8 is connected to the wall 2 above the crown beam 9. A fixed pulley 10 is provided at the other end of the triangular support 8 away from the wall 2, and the fixed pulley 10 is rotatably connected to the top of the triangular support 8. The fixed pulley 10 is provided with a third groove 101. A portion of the support rope 7 is located within the third groove 101 and abuts against a portion of the inner wall of the third groove 101. In this embodiment, when a portion of the support rope 7 is located in the third groove 101 and the first groove 421 respectively, the support rope 7 is located in a plane perpendicular to the wall 2 and the horizontal ground. The longitudinal and transverse distances between the fixed pulley 10 and the fixed end 5 and the first support column 42 are consistent, thereby making the first support column 42 uniformly subjected to the force of the rope and oriented towards the crossbeam 1. This makes the support of the shell 4 on the crossbeam 1 more stable and the direction meets the support requirements.

[0070] The number of triangular supports 8 and fixed pulleys 10 can be multiple, and they can be set on the wall 2 above the crown beam 9 or on the horizontal ground as needed. The size can be selected according to the usage requirements. In this embodiment, for ease of description, three triangular supports 8 and fixed pulleys 10 are used. One is set on the wall 2 above the crown beam 9, and the other two are set on the horizontal ground. The smaller triangular support 8 and fixed pulley 10 are set near the take-up end 6. The rope of the support rope 7 abuts against the fixed pulley 10 on the side of the wall 2, the fixed pulley on the horizontal ground away from the take-up end 6, and the fixed pulley near the take-up end 6 in sequence, and is routed in the manner shown in the figure. This makes the rope of the support rope 7 taut, and the change in the direction and magnitude of the force on the rope is relatively gradual, so that the force on the support rope 7 and the shell 4 is relatively stable.

[0071] In some embodiments, such as Figures 1-5 As shown, the end of the first support column 42 facing the other wall 2 adopts a hemispherical structure, and the spherical surface faces the other wall 2. The first groove 421 is opened along the spherical surface of the first support column 42, so that the rope body of the support rope 7 has a larger contact area with the first groove 421, thus making the support rope 7 more stable when it abuts against the first support column 42.

[0072] The sides of the first support column 42 are perpendicular to the side of the shell 4 facing the other wall 2.

[0073] In some embodiments, such as Figures 1-5 As shown, a second support column 43 is provided on both the upper and lower sides of the first support column 42. Both second support columns 43 are rectangular in structure and are located at the center of the side of the shell 4 facing the other wall 2. The center of the end face of the two second support columns 43 that contacts the shell 4 and the center of the end face of the first support column 42 that contacts the shell 4 are both located on the centerline of the side of the shell 4. The two second support columns 43 are symmetrically arranged with respect to the first support column 42, and the end of each second support column 43 facing the other wall 2 is a hemispherical structure with the spherical surface facing the other wall 2. The distance between the spherical end of the second support column 43 and the other wall 2 is small. The distance between one end of the spherical surface of the first support column 42 and the other wall 2 is greater than the distance between the end of the fixed end 5 facing the other wall 2 and the other wall 2. The second support column 43 is provided with a second groove 431 opened along the spherical surface. The second groove 431 is located in a plane that is perpendicular to both the wall 2 and the horizontal ground. Parts of the support rope 7 are respectively set in the two second grooves 431, and the inner sidewalls of the second grooves 431 abut against each other. This makes the position of the support rope 7 relatively stable when it abuts against the shell 4, and the direction of the force meets the support requirements, thereby making the support of the shell 4 on the beam 1 more stable.

[0074] In some embodiments, such as Figure 1As shown, the end faces of the upper and lower sidewalls of the groove 41 away from the inner sidewall of the groove 41 are both arc-shaped, and the arc faces of the upper and lower sidewalls of the groove 41 are set facing each other. Specifically, when the housing 4 abuts against the crossbeam 1, the groove opening opposite the inner sidewall of the groove 41 faces the crossbeam 1. The upper and lower groove walls of the groove 41 are both arc-shaped, so that when the crossbeam 1 is inserted into the groove 41, it will not be obstructed by the upper and lower end faces of the housing 4 with the groove 41. This makes it easier to install the housing 4 onto the crossbeam 1 and reduces the probability of the housing 4 colliding with the crossbeam 1.

[0075] In some embodiments, such as Figures 7-8 As shown, the fixed end 5 includes two triangular plates 51 arranged opposite each other, and a connecting block 52 is provided between the triangular plates 51. Specifically, the connecting block 52 adopts a rectangular structure, and the triangular plates 51 adopt an equilateral triangle structure. The connecting block 52 is located at the center of the triangular plates 51. The connecting block 52 has a through rope groove 521, and the groove between the two ends of the rope groove 521 is located on one side of the connecting block 52, so that the support rope 7 can be easily installed into the rope groove 521 through the groove.

[0076] In this embodiment, as Figures 9-10 As shown, one end of the support rope 7 is provided with a limiting end 71. Specifically, the limiting end 71 adopts a spherical structure, and the diameter of the sphere is larger than the radial dimension of the support rope 7 and larger than the dimension of the rope groove 521. When the support rope 7 is installed into the rope groove 521, the limiting end 71 is located on the lower side of the rope groove 521 and abuts against the side of the connecting block 52, thereby limiting the support rope 7 and stabilizing the position of the support rope 7.

[0077] In this embodiment, as Figures 9-12As shown, the upper side of the limiting end 71 of the support rope 7 is provided with two rectangular fixing plates 30. The support rope 7 passes through the center of the two fixing plates 30. Specifically, the fixing plate 30 located on the lower side is fixedly connected to the support rope 7 and can move through the upper fixing plate 30. In this embodiment, bolt holes 40 are provided at the four corners of the two fixing plates 30, and the opposite sides of the two fixing plates 30 are provided with fitting grooves 301 that are adapted to the connecting plate. The upper and lower surfaces of the connecting plate are provided with bolt holes 40 corresponding to the two fixing plates 30. When the support rope 7 is installed to the fixing end 5, the upper fixing plate 30 is first moved upward, so that space for the connecting block 52 is created between the two fixing plates 30. Then, the support rope 7 is installed into the rope groove 521. At this time, the support rope 7 is pulled upward, so that the lower half of the connecting plate is inserted into the fitting groove 301 of the lower fixing plate 30. The adapter groove 301 and the groove wall opposite to the connecting plate abut against the lower side of the connecting plate. Then, the upper fixing plate 30 is moved downward, so that the upper plate part of the connecting plate is inserted into the adapter groove 301 of the upper fixing plate 30 and abuts against the groove wall of the adapter groove 301 of the upper fixing plate 30. At the same time, the opposite end faces of the two fixing plates 30 abut and fit together. Then, bolts are used to connect the connecting plate and the upper and lower fixing plates 30, so that the support rope 7 is stably connected to the fixing end 5. The adaptation and connection of the two fixing plates 30 and the connecting plate improves the structural strength of the fixing end 5, thereby making the installation of the support rope 7 more stable. In addition, the lower limiting end 71 is used as a safety measure to prevent the support rope 7 from sliding directly out of the fixing plate 30 when the connection between the lower fixing and the support rope 7 is unstable, thereby further improving the stability of the structure.
