Description

Technical Field

[0001] This invention relates to the field of tunnel technology, specifically to a leveling component and substructure assembly for a tunnel. Background Technology

[0002] In the field of tunnel construction technology, prefabricated components have been widely used. Besides tunnel lining, there are increasingly more cases of using prefabricated substructures within tunnels. During the assembly of prefabricated substructure components, precise positioning is a crucial step; inaccurate positioning can even prevent subsequent assembly. Taking the installation of prefabricated substructure components in shield tunnels as an example, during the construction of shield tunnels, various uncertainties such as geology and construction can lead to misalignment between adjacent tunnel segments. This misalignment can cause difficulties in the installation of the substructure. Severe misalignment can cause the longitudinal connecting bolt holes of the substructure to become misaligned, making it impossible to complete the prefabrication of the substructure. In such cases, the common practice in engineering is to place steel shims at the bottom of the tunnel segment to adjust the position of the substructure and eliminate the impact of segment misalignment.

[0003] Currently, when using steel shims to level the substructure, the required height of the steel shims is estimated based on the misalignment of the tunnel segments. The steel shims are then laid at the installation location, and the substructure is hoisted onto the steel shims. The flatness of the substructure is then re-measured. If it does not meet the requirements, the substructure needs to be hoisted again, and the number of shims needs to be adjusted. This process is repeated until the substructure is level.

[0004] As can be seen from the above, this method mainly has the following technical defects: adjusting the height of the lower structure by adjusting the number of steel shims has low accuracy and poor adjustment effect; the shims can only raise the lower structure, and when the misalignment of the tunnel segments requires lowering the position of the lower structure, the shim method cannot be applied, as the lower structure needs to be lifted for each adjustment, which is time-consuming and cumbersome. Due to the randomness of the misalignment of the tunnel segments, the steel shims are often placed by construction personnel according to the site conditions, and their stability has not been calculated in the design, which makes them prone to displacement under construction loads. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a leveling component and a substructure assembly for tunnels, which can solve the problem that the existing technology uses shims to adjust the substructure of tunnels, which requires lifting each time and has poor accuracy, thus affecting construction efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] On one hand, the present invention provides a leveling component for the substructure of a tunnel, characterized in that it comprises:

[0008] A chute, used to set the lower part of the substructure, is inclined;

[0009] The inclined support has an inclined top surface and is slidably connected to the groove.

[0010] A driving component, connected to the inclined support component, is used to drive the inclined support component to move relative to the slide groove, so as to adjust the height at which the inclined support component supports the lower structure.

[0011] In some alternative solutions, the drive element includes:

[0012] A threaded sleeve, which is used to be embedded in the lower structure;

[0013] A vertical chute, which is connected to the inclined support member;

[0014] An adjusting screw passes through the threaded sleeve and is threadedly engaged with the threaded sleeve. One end is connected to the vertical slide groove and can slide vertically relative to the vertical slide groove. The other end is used to drive the adjusting screw to rotate relative to the threaded sleeve, so as to adjust the position of the inclined support relative to the slide groove.

[0015] In some alternative solutions, the relationship between the chute and the inclined support member satisfies αtanθ<μ1, where α is the safety factor, v1 is the coefficient of friction between the chute and the inclined support member, and θ is the inclination angle of the chute.

[0016] In some alternative solutions, the maximum preload F of the adjusting screw satisfies: Where G is the weight of the substructure, μ2 is the coefficient of friction between the inclined support and the support structure below it, G0 is the self-weight of the leveling component, n is the number of leveling components, and ∝ is the safety factor.

[0017] In some alternative solutions, the end of the adjusting screw connected to the vertical slide groove is provided with a sliding ball, the vertical slide groove is provided with several vertical sliding cavities in the downward direction, the vertical sliding cavity is provided with a vertical opening on the side facing the adjusting screw, and the sliding ball is provided in the vertical sliding cavity for vertical sliding.

[0018] In some alternative embodiments, the end of the adjusting screw used to drive the adjusting screw to rotate relative to the threaded sleeve is provided with a rotating handle.

[0019] In some alternative solutions, the chute is provided with a T-shaped slide rail, and the upper top surface of the inclined support is provided with a T-shaped slider that matches the T-shaped slide rail. The chute and the inclined support are slidably connected through the T-shaped slide rail and the T-shaped slider.

[0020] In some alternative embodiments, the inclined support includes:

[0021] Base plate;

[0022] A top plate, which is spaced apart from the bottom plate and is inclined;

[0023] A right-angled trapezoidal plate, with one side perpendicular to the upper and lower bases connected to the base plate, and the other side connected to the top plate.

[0024] On the other hand, the present invention also provides a substructure component inside a tunnel, comprising:

[0025] The lower structure has multiple leveling mounting slots at its bottom.

[0026] The leveling components, having the same number as the leveling mounting slots, include:

[0027] - A sliding groove, which is located in the leveling mounting groove and connected to the lower structure, and is inclined;

[0028] - An inclined support member with an inclined top surface that is slidably connected to the groove;

[0029] - A driving component, which is connected to the inclined support component, is used to drive the inclined support component to move relative to the slide groove in order to adjust the height at which the inclined support component supports the lower structure.

[0030] In some alternative designs, the bottom of the lower structure is provided with a leveling mounting groove located at the four corners of the rectangle.

[0031] Compared with existing technologies, the advantages of this invention are as follows: After the lower structure, together with the leveling component, is lowered to the set position on the placement surface, the bottom surface of the inclined support member contacts the placement surface. When the lower structure is unstable, the inclined support member is driven to move relative to the slide groove by the driving component. Since the slide groove is inclined, the bottom surface of the inclined support member is always in contact with the placement surface when the inclined support member moves relative to the slide groove. The distance between the slide groove and the placement surface will change, which is equivalent to adjusting the height of the inclined support member supporting the lower structure, thereby achieving leveling of the lower structure. Compared with the shim method used in existing solutions, this solution, due to the inclined setting of the slide groove and its sliding connection with the top surface of the inclined support member, allows for virtually stepless height adjustment. Only the slide groove and the inclined support member need to be adjusted, and it is not affected by the thickness of the shim. In addition, by driving the inclined support member to move relative to the slide groove by the driving component, the height of the corresponding position of the lower structure can be directly adjusted without lifting the entire lower structure, which also improves construction efficiency.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] like Figures 1 to 3 As shown, the present invention provides a leveling component for the lower structure of a tunnel, comprising: a chute 1, an inclined support 3, and a driving component 4.

[0048] The slide 1 is used to set the lower part of the lower structure 2 and is inclined; the top surface of the inclined support 3 is inclined and slidably connected to the slide 1; the driving member 4 is connected to the inclined support 3 and is used to drive the inclined support 3 to move relative to the slide 1 to adjust the height of the inclined support 3 supporting the lower structure 2.

[0049] When using the tunnel substructure leveling component, multiple leveling components can be set below the substructure 2, specifically according to design requirements. The chute 1 of the leveling component is set below the substructure 2, and the top surface of the inclined support 3 is inclined and slidably connected to the chute 1. After the substructure 2 together with the leveling component is lowered to the set position on the placement surface, the bottom surface of the inclined support 3 contacts the placement surface. When the substructure 2 is unstable, the inclined support 3 is driven to move relative to the chute 1 by the driving component. Since the chute 1 is inclined, when the inclined support 3 moves relative to the chute 1, the bottom surface of the inclined support 3 is always in contact with the placement surface, and the distance between the chute 1 and the placement surface will change, which is equivalent to adjusting the height of the inclined support 3 supporting the substructure 2, thereby achieving the leveling of the substructure 2. Compared to the existing method of using shims, this solution, due to the inclined setting of the slide 1 and its sliding connection with the top surface of the inclined support 3, allows for virtually stepless height adjustment. Only the slide 1 and the inclined support 3 need to be adjusted, without being affected by the thickness of the shims. In addition, by driving the inclined support 3 relative to the slide 1 through the drive component 4, the height of the corresponding position of the lower structure 2 can be directly adjusted without lifting the entire lower structure 2, thus improving construction efficiency.

[0050] In this example, the lower structure 2 can be a box culvert or an integral curved component, etc. The placement surface to which the lower structure 2 is placed refers to the ground, tunnel segments, or installation platform. The inclined setting of the slide 1 refers to the vertical inclination, that is, the angle between it and the horizontal plane. In addition, in this example, a leveling mounting groove is provided below the lower structure 2 for installing leveling components. Furthermore, when the bottom surface of the inclined support 3 is flush with the bottom surface of the lower structure 2, the inclined support 3 is at the limit position of the upper stroke of the slide 1, that is, the inclined support 3 can only slide in the direction extending out of the leveling mounting groove.

[0051] like Figures 3 to 9 As shown, in some optional embodiments, the driving component 4 includes: a threaded sleeve 41, a vertical groove 42, and an adjusting screw 43. The threaded sleeve 41 is embedded in the lower structure 2; the vertical groove 42 is connected to the inclined support 3; the adjusting screw 43 passes through the threaded sleeve 41 and is threadedly engaged with the threaded sleeve 41, one end of which is connected to the vertical groove 42 and can slide vertically relative to the vertical groove 42, and the other end is used to drive the adjusting screw 43 to rotate relative to the threaded sleeve 41 to adjust the position of the inclined support 3 relative to the groove 1.

[0052] In some optional embodiments, the top surface of the leveling mounting groove is also inclined. The slide 1 is embedded in the top surface of the leveling mounting groove. The threaded sleeve 41 is embedded in the lower structure 2 on the side of the leveling mounting groove. The adjusting screw 43 passes through the threaded sleeve 41 and is threadedly engaged with the threaded sleeve 41. Rotating the adjusting screw 43 can drive the inclined support 3 to move relative to the slide 1. The inclined support 3 will move vertically relative to the lower structure 2. Since the bottom surface of the inclined support 3 abuts against the placement surface, the lower structure 2 can be lifted or lowered under the force of the inclined support 3, thereby realizing the height adjustment of the corresponding position of the lower structure 2.

[0053] In some optional embodiments, the relationship between the slide 1 and the inclined support 3 satisfies αtanθ<μ1, where α is the safety factor, μ1 is the coefficient of friction between the slide 1 and the inclined support 3, and θ is the inclination angle of the slide 1.

[0054] In this embodiment, the relationship between the slide 1 and the inclined support 3 satisfies αtanθ<μ1, which enables the lower structure 2 and the inclined support 3 to achieve self-stability through friction without external force, thus preventing the inclined support 3 from slipping off the slide 1 when the lower structure 2 is lifted. The safety factor α is taken as 1.1.

[0055] In some optional embodiments, the maximum preload F of the adjusting screw 43 satisfies: Where G is the weight of the lower structure 2, μ2 is the coefficient of friction between the inclined support 3 and its lower surface, G0 is the self-weight of the leveling component, n is the number of leveling components, and ∝ is the safety factor.

[0056] In this embodiment, by This ensures that when the lower structure 2 requires leveling, the preload provided by the adjusting screw 43 is sufficient to overcome the friction between the inclined support 3 and the slide 1 and the placement surface, allowing the adjusting screw 43 to push the inclined support 3 relative to the slide 1. In this example, when four sets of leveling components are used, i.e., n is 4, and the four leveling components are located below the lower structure 2 and at the four corners of the rectangle, jointly supporting the lower structure 2 and leveling it. The safety factor ∝ is between 1.05 and 1.1.

[0057] Furthermore, the adjustment height h of the lower structure 2 is determined according to the formula h = m / stanθ, where m is the number of rotations of the adjusting screw 43 and s is the pitch of the adjusting screw 43. When the end of the adjusting screw 43 is turned out of the lower structure 2 to the specified scale, the lower structure 2 will be raised accordingly to the specified scale height. The adjusting screw 43 can convert the torque at the nut end (i.e., the end located on the outside of the lower structure 2) into thrust through the thread, pushing the inclined support 3, thereby raising the lower structure 2 to achieve leveling. By using h = m / stanθ, the number of rotations can be calculated from the pre-lifting height, and combined with the scale on the adjusting screw, precise leveling of the lower structure 2 can be achieved.

[0058] In some optional embodiments, a ball 431 is provided at one end of the adjusting screw 43 connected to the vertical slide groove 42. The vertical slide groove 42 is provided with several vertical sliding cavities 421 in the downward direction. The vertical sliding cavity 421 has a vertical opening on the side facing the adjusting screw 43. The ball 431 is provided in the vertical sliding cavity 421 and can slide vertically.

[0059] In this embodiment, the diameter of the slider 431 is larger than the width of the vertical opening. The adjusting screw 43 passes through the vertical opening and engages the slider 431 within the vertical groove 42. The vertical groove 42 is connected to the inclined support 3 and is vertically positioned. When the adjusting screw 43 is rotated to push the inclined support 3 to move relative to the groove 1, the slider 431 moves vertically within the vertical cavity 421 relative to the inclined support 3. When the adjusting screw 43 pulls the inclined support 3 to move relative to the groove 1, the slider 431 is engaged within the vertical cavity 421, providing pulling force for the movement of the inclined support 3, and moves vertically downward relative to the inclined support 3 within the vertical cavity 421.

[0060] In some alternative embodiments, the end of the adjusting screw 43 used to drive the adjusting screw 43 to rotate relative to the threaded sleeve 41 is provided with a rotating handle.

[0061] In this embodiment, a rotating handle is provided at the end of the adjusting screw 43 used to drive the adjusting screw 43 to rotate relative to the threaded sleeve 41, so that the adjusting screw 43 can be rotated to drive the inclined support 3 to move relative to the inclined support 3.

[0062] In some optional embodiments, the slide 1 is provided with a T-shaped slide 11, and the upper top surface of the inclined support 3 is provided with a T-shaped slider 34 that matches the T-shaped slide 11. The slide 1 and the inclined support 3 are slidably connected through the T-shaped slide 11 and the T-shaped slider 34.

[0063] In this embodiment, the slide groove 1 and the inclined support 3 are slidably connected by the T-shaped slide rail 11 and the T-shaped slider 34. Since the slide groove 1 is embedded in the lower structure 2, the threaded sleeve 41 is also embedded in the lower structure 2. The vertical slide groove 42 is connected to the inclined support 3. The adjusting screw 43 passes through the threaded sleeve 41 and engages with it by thread, and one end is locked in the vertical slide cavity 421 by the ball 431. When the lower structure 2 is hoisted, the inclined support 3 will not slip due to the locking of the ball 431. The cooperation of the T-shaped slide rail 11 and the T-shaped slider 34 can also maintain the relative stability of the slide groove 1 and the inclined support 3.

[0064] In some alternative embodiments, the inclined support 3 includes a base plate 31, a top plate 32, and a right-angled trapezoidal plate 33.

[0065] The top plate 32 is spaced apart from the bottom plate 31 and is inclined; the right-angled trapezoidal plate 33 has one side perpendicular to the upper and lower bases connected to the bottom plate 31, and the other side connected to the top plate 32.

[0066] In this embodiment, the right-angled trapezoidal plate 33 is connected to the bottom plate 31 via one of its vertical sides (the upper and lower bases) and to the top plate 32 via the other side, thus tilting the top plate 32. Additionally, the vertical slide 42 is connected to the lower base of the right-angled trapezoidal plate 33. This allows the inclined support member 3 to move away from the lower structure 2 (i.e., outward from the leveling mounting groove 21) when the adjusting screw 43 pushes the inclined support member 3 relative to the slide 1, thereby raising the lower structure 2. Conversely, when the inclined support member 3 is pulled relative to the slide 1, it moves closer to the lower structure 2 (i.e., into the leveling mounting groove 21), thereby lowering the height of the lower structure 2.

[0067] like Figure 10 and Figure 11As shown, on the other hand, the present invention also provides a substructure assembly for a tunnel, comprising: a substructure 2 and leveling components 10. The bottom of the substructure 2 is provided with a plurality of leveling mounting grooves 21, and the number of leveling components 10 is the same as the number of leveling mounting grooves 21. The leveling component 10 includes: a sliding groove 1, an inclined support 3, and a driving component 4. The sliding groove 1 is disposed in the leveling mounting groove 21 and connected to the substructure 2, and is inclined; the upper top surface of the inclined support 3 is inclined and slidably connected to the sliding groove 1; the driving component 4 is connected to the inclined support 3 and is used to drive the inclined support 3 to move relative to the sliding groove 1 to adjust the height of the inclined support 3 supporting the substructure 2.

[0068] In this example, after the lower structure 2, along with the leveling component, is lowered to the designated position on the placement surface, the bottom surface of the inclined support 3 contacts the placement surface. When the lower structure 2 is unstable, the inclined support 3 is moved relative to the slide 1 by the driving component. Since the slide 1 is inclined, the bottom surface of the inclined support 3 remains in contact with the placement surface as it moves relative to the slide 1, changing the distance between the slide 1 and the placement surface. This effectively adjusts the height of the lower structure 2 supported by the inclined support 3, thus achieving leveling of the lower structure 2. Compared to the existing method using shims, this solution, due to the inclined setting of the slide 1 and its sliding connection with the top surface of the inclined support 3, allows for virtually stepless height adjustment. Only the slide 1 and the inclined support 3 need to be adjusted, unaffected by the thickness of the shims. Furthermore, by driving the inclined support 3 relative to the slide 1 with the driving component 4, the height of the corresponding position of the lower structure 2 can be directly adjusted without lifting the entire lower structure 2, thus improving construction efficiency.

[0069] In this example, the leveling component used can be any of the leveling components described above.

[0070] In some optional embodiments, the bottom of the lower structure 2 is provided with four leveling mounting slots 21, located at the four corners of the rectangle.

[0071] In this embodiment, the bottom of the lower structure 2 is provided with four leveling mounting slots 21, which are located at the four corners of the rectangle. Each leveling mounting slot 21 is equipped with a leveling component, which can facilitate the leveling of the lower structure 2.
