[0002] With the continuous development of transportation infrastructure, the number of highway and railway tunnel constructions has been increasing continuously, and tunnel construction technologies have also been constantly progressing. In order to improve the stability and safety of tunnels, the quality requirements for tunnel secondary lining (referred to as "secondary lining" for short) construction are getting higher and higher. The secondary lining needs to have sufficient strength, durability, and waterproof performance, which directly relates to the overall quality and service life of the tunnel. And the key equipment for secondary lining construction - the secondary lining trolley, its construction accuracy and quality have an important impact on the overall quality of the tunnel. However, there are many problems with the traditional gantry support structure of the secondary lining trolley in practical applications, which limit its wide application and efficient use in modern tunnel construction.

[0003] The overall structure of the traditional secondary lining trolley is relatively complex. As Figure 1 shown, generally a gantry is used,配合 with a large number of scaffolding set around. The structure is complex and inconvenient to disassemble and assemble. In addition, the existence of the scaffolding restricts the passage and construction of other construction vehicles inside the secondary lining trolley. The formwork structure of the traditional secondary lining trolley is relatively complex, and a large number of support structures are arranged inside to ensure the strength of the formwork, which will affect the passage height and passage area of construction vehicles inside the trolley. Content of the Utility Model

[0006] A formwork for the frame structure of a secondary lining trolley includes a top formwork group and two side formwork groups. The formwork is integrally arc-shaped. The top formwork group is pressed on the upper longitudinal beam of the matching support base to form an integral structure. The two side formwork groups are respectively hinged on both sides of the top formwork group. There is no cross beam arranged along the width direction of the trolley on the frame structure;

[0036] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0037] like Figure 2-16 As shown, this embodiment discloses a secondary lining trolley frame structure, comprising a formwork and a support base. The formwork of the secondary lining trolley frame structure comprises a top formwork assembly and a side formwork assembly. The support base comprises support columns 2 arranged on both sides, a U-shaped pedestal supporting the bottom, and an upper longitudinal beam 4. The number of support columns 2 on each side is at least two, and may be three or more. The upper longitudinal beam 4 is connected to the support columns 2 above, and is connected to the support columns 2 via support column flange plates 3.

[0038] The formwork is pressed into place in an arc shape on the upper longitudinal beam 4, forming a single, integrated structure. The frame structure lacks crossbeams extending across the width of the trolley. Removing these crossbeams reduces structural complexity and improves versatility, making the entire frame more adaptable to various tunnel environments. Furthermore, the frame's access area is increased, allowing large construction machinery to operate via the secondary lining trolley. This allows for increased use of machinery in secondary lining construction, replacing manual labor. For example, truck-mounted pumps can be used for grouting, replacing traditional grouting methods.

[0039] The formwork includes a top formwork group and two side formwork groups. The top formwork group consists of multiple top formworks 27 arranged along the length direction of the trolley. The side formwork group consists of multiple side formworks 30 arranged along the length direction of the trolley. Specifically, the top formwork group is composed of 8 arc-shaped top formworks 27 arranged along the length direction of the trolley, and each side's side formwork is composed of 8 arc-shaped side formworks 30 arranged along the length direction of the trolley. The top formwork 27 and the side formwork 30 are hinged by means of a hinged connection. On both sides of the top formwork 27, top formwork hinge ears 35 are provided, and on one side of the side formwork 30, side formwork hinge ears 43 are provided. The top formwork hinge ears 35 and the side formwork hinge ears 43 are hinged by a pin shaft.

[0040] Each top formwork 27 is composed of a long arc-shaped panel 41, six side plates 42, at least twelve reinforcing square pipes 36, support square pipes 39, and three main stress-bearing frames 37. The main stress-bearing frames 37 are welded by square pipes 38, and the main stress-bearing frames 37 are in the shape of a Chinese character 'Ri' or 'Mu'. The six side plates 42 are evenly fixed to both sides of the main stress-bearing frame by welding. On the same side, L-shaped connecting plates 40 are provided at the inner edges of adjacent side plates 42. The bottom of the L-shaped connecting plates 40 is fixed inside the side plates 42 by bolts, and adjacent two L-shaped connecting plates 40 are connected by bolts. This modular splicing method can significantly improve the construction convenience and the adaptability of the formwork. Different top formworks 27 are connected by bolts for easy replacement, or are more firmly connected by welding.

[0041] The long arc-shaped panel 41 is welded above the side plates 42 using a mixed material of stainless steel and carbon steel. The stainless steel layer of the long arc-shaped panel 41 provides a smooth contact surface for the concrete surface, reducing surface roughness, and at the same time has corrosion resistance to avoid corrosion reactions when the formwork contacts the concrete. The carbon steel layer provides strength and hardness to ensure that the formwork is not easily deformed under the concrete pouring pressure.

[0042] Reinforcing square pipes 36 are welded on the back of the formwork. These reinforcing square pipes 36 significantly enhance the stability of the formwork, can withstand greater pressure and tension, and prevent the formwork from deforming or cracking during use. The reinforcing square pipes 36 are connected to the stress-bearing frames 37 by support square pipes 39 to form a more stable structure, effectively dispersing stress and enhancing the overall strength.

[0043] The side formwork group is composed of a short arc-shaped panel 41, four side plates 42, at least twelve reinforcing square pipes 36, support square pipes 39, and two main stress-bearing frames 37. The main stress-bearing frames 37 are welded by square pipes 38. The short arc-shaped panel 41 is also welded above the side plates 42 using a mixed material of stainless steel and carbon steel, and reinforcing square pipes 36 and support square pipes 39 are welded on the back.

[0044] The formwork features an overall circular design, eliminating the need for gantry support in traditional structures, achieving lightweight and modular design. The mesh-like structure evenly distributes stress while reducing space requirements. The circular design also offers high stability, capable of withstanding forces from all directions, effectively preventing the formwork from tilting or collapsing during use, improving construction safety and efficiency.

[0045] During installation, the modules only need to be joined together, and they can be easily disassembled into individual modules for easy transportation and storage, significantly saving manpower and time, and improving construction efficiency. In addition, adjacent top formworks 27 are connected by bolts or welding, ensuring a secure connection and facilitating assembly and disassembly.

[0046] With the rapid development of transportation infrastructure, the number of tunnel construction projects continues to grow, and the quality requirements for tunnel secondary lining construction are gradually increasing. Traditional trolleys commonly suffer from heavy weight, complex structures, low construction efficiency, difficult quality control, and poor adaptability. The present utility model significantly improves these shortcomings of traditional formwork by introducing a main load-bearing frame 37 splicing structure, a ring formwork design, and a modular assembly method, ensuring construction strength, durability, waterproof performance, and quality control capabilities.

[0047] The U-shaped pedestal consists of two vertical support devices on either side and a lower frame grid 23. The lower frame grid 23 and the vertical support devices are connected by a frame connection mechanism 24. This connection, combined with the integral frame structure formed by the upper longitudinal beams 4 and support columns 2, ensures the stability and structural integrity of the trolley even when bearing heavy loads. The lower frame 23 is supported by lower frame anchors 25 and connected with bolts and nuts. A simple adjustment of the nuts allows for easy adjustment of the frame height to suit different construction conditions.

[0048] The secondary lining trolley support base moves the overall force center of gravity downward by connecting the lower frame grid 23 with the support mechanisms on both sides. The structure is more stable and has stronger pressure capacity. It can better adapt to these complex construction conditions and ensure the safety and smooth progress of construction.

[0049] The support base of the secondary lining trolley does not have too many connection points with the formwork, which allows it to better adapt to tunnels with different cross-sections. The design of the support mechanism allows it to be flexibly adjusted according to different tunnel sections, improving its adaptability and versatility. In addition, it reduces construction problems caused by improper connection between the formwork and the support mechanism, improving construction quality and efficiency. The vertical support device includes a middle longitudinal beam 4, a lower longitudinal beam 16 that can slide vertically relative to the middle longitudinal beam 4, and a frame connection mechanism 24 between one side of the lower frame 23 and the lower longitudinal beam 16. This welding or bolting method makes the assembly between the lower frame 23 and the lower longitudinal beam 16 more stable, and facilitates subsequent disassembly and maintenance.

[0050] A center longitudinal beam side flange plate 8 is provided on the outer side surface of the center longitudinal beam 4 , and a center longitudinal beam side ear plate 9 is provided on the center longitudinal beam side flange plate 8 .

[0051] Eight expansion and contraction formwork cylinder lugs 19 are installed on the outer side of the lower longitudinal beam 16, secured by welding (or bolts). One end of the expansion and contraction formwork cylinder 15 is connected to the expansion and contraction formwork cylinder lugs 19, and the other end is hinged to the side formwork. Lower longitudinal beam flanges 17 are installed at both ends of the lower longitudinal beam 16, connected by welding or bolts. Support cylinders 14 connect the center longitudinal beam 4 and the lower longitudinal beam 16, which are connected by a vertical sliding mechanism. The vertical sliding mechanism allows for flexible vertical adjustment of the U-shaped pedestal, ensuring stable support for the formwork 27 even when the tunnel cross-section dimensions change, improving construction accuracy and efficiency. The vertical sliding mechanism includes multiple guide cylinders 12 fixedly connected to the bottom of the center longitudinal beam 4 and multiple guide openings 26 located on the top of the lower longitudinal beam 16. The shape of the guide openings 26 matches that of the guide cylinders 12, allowing the guide cylinders 12 to slide freely within the guide openings 26. This design ensures smooth vertical movement by limiting the sliding direction of the lower longitudinal beam 16 and reducing potential deflection due to external forces. Furthermore, to enhance the rigidity and stability of the guide mechanism, a guide flange plate 11 is provided at the rear end of the guide cylinder 12 and reinforced with guide mechanism reinforcement ribs 13 via welding. The center longitudinal beam guide flange plate 10 is located at the bottom of the center longitudinal beam 4 and bolted to the center longitudinal beam guide flange plate 11.

[0052] During the formwork's lifting and retraction processes, the vertical sliding mechanism guides the support mechanism, ensuring accurate movement and enhancing its stability. Furthermore, during tunnel construction, the complex construction environment can present various external interference forces, such as vibration and wind. The guide mechanism effectively resists these external interference forces, ensuring stable operation of the support mechanism.

[0053] The vertical sliding mechanism and the lifting cylinder 28 work together to raise and retract the formwork. While the support cylinder provides the lifting force, the vertical sliding mechanism ensures the formwork's precise trajectory, preventing deviation or tilt. This collaborative approach improves the efficiency and reliability of the support mechanism, ensuring construction quality and safety.

[0054] A longitudinal beam support 21 is provided below the lower longitudinal beam 16, and a vertical telescopic support device 22 is provided below the longitudinal beam support 21. The lower longitudinal beam 16 is provided obliquely above the lower frame grid 23. This layout leaves installation space for the traveling mechanism so that the traveling mechanism can be installed below the lower longitudinal beam 16. A jacking and transverse movement support device 20 is provided at both ends of each middle longitudinal beam 4. The jacking and transverse movement support device 20 is not only used to adjust the height of the middle longitudinal beam 4, but also to ensure the precise positioning of the template. The jacking and transverse movement support device 20 includes a vertical jacking cylinder 28 hinged to the middle longitudinal beam 4, a jacking and transverse movement jacking support 31 hinged to the jacking cylinder 28, and a transverse movement device fixed at the bottom of the jacking and transverse movement jacking support 31. The tail end of the jacking cylinder 28 is fixed to the upper end earring 29 of the jacking and transverse movement support device 20 by a pin; the top end of the jacking cylinder 28 is fixed to the middle longitudinal beam end ear plate 6 by a pin, and the middle longitudinal beam end ear plate 6 is installed on the middle longitudinal beam end flange plate 5 at both ends of the middle longitudinal beam 4. The middle longitudinal beam end reinforcement rib 7 is installed on the back side of the middle longitudinal beam end flange plate 5. The jacking cylinder 28 provides a strong jacking force for adjusting the frame to the target height, while the jacking and transverse movement jacking support 31 and the transverse movement device ensure the accuracy of the horizontal adjustment, thereby better centering.

[0055] The transverse movement device includes a transverse movement mechanism 33 and a transverse movement base 34, and the transverse movement mechanism 33 and the transverse movement base 34 are connected by a horizontal linear power device. The linear power device ensures the accuracy and controllability of the transverse movement, thereby reducing errors in the adjustment process and simplifying the operation. The horizontal linear power device can adopt a hydraulic cylinder, a linear motor, etc. The jacking and transverse movement support device 20 includes a jacking and transverse movement housing 32 for guidance arranged on the outside of the jacking and transverse movement jacking support 31. The jacking and transverse movement housing 32 is fixedly connected to the lower longitudinal beam 16 through the lower longitudinal beam flange plate 17. This housing design not only provides additional protection, but also ensures the precise positioning and smooth operation of the components during the jacking process.

[0056] A longitudinal support 21 is located beneath the lower longitudinal beam 16. A vertically retractable support device 22 is installed at the bottom of the longitudinal support 21. This device allows for frame adjustment in complex terrain, improving construction adaptability and effectively reducing stability issues caused by uneven terrain. Furthermore, four support cylinder lugs 18 are located on either side of the lower longitudinal beam 16, connecting to the support cylinders 14. These lugs are hinged to the lugs on the center longitudinal beam 4.

[0057] The jacking and transverse shifting support device 20 can quickly and accurately achieve fine-tuning of the trolley. Cooperating with the support cylinder 14, it can ensure that the thickness and profile of the secondary lining meet the design requirements, and ensure the waterproof performance, structural strength and appearance quality of the tunnel. The operation process of the trolley frame is as follows: the jacking and transverse shifting shell 32 is set at both ends of the lower longitudinal beam 16; the jacking and transverse shifting jacking support 31 and the jacking and transverse shifting shell 32 are in a non-powered sliding connection relationship; after the trolley is in place, the jacking cylinder 28 extends to make the jacking and transverse shifting base 34 contact the ground to support the entire trolley body; after the transverse shifting base 34 lands, the support cylinder 14 extends to make the lower frame grid 23 contact the ground, making the overall support mechanism more stable; if the trolley as a whole needs to be adjusted laterally, the support cylinder 14 retracts to make the lower frame grid 23 rise, and the transverse shifting mechanism 33 can move left and right to fine-tune the trolley as a whole. After the adjustment, the support cylinder 14 extends to make the lower frame grid 23 contact the ground to support the overall mechanism. In addition, the vehicle passing trestle can be erected on the lower frame grid 23. In order to reduce the vibration of the vehicle passing trestle transmitted to the trolley itself, affecting the grouting and vibration quality, the vehicle passing trestle is directly supported on the ground by a supporting mechanism. There are multiple mesh holes on the lower frame grid 23 for the supporting mechanism to pass through. The vehicle passing trestle can be suspended on the lower frame grid 23 and has no connection to the lower frame grid 23, or it can have a simple connection.

[0058] The secondary lining trolley frame structure is provided with a lower frame grid 23, on which a plurality of mesh holes are provided. The vehicle-passing trestle is suspended on the lower frame grid 23 by a supporting device passing through the mesh holes. The vehicle-passing trestle will not transmit vibration to the trolley and will not affect the construction quality of the secondary lining.

[0059] The support mechanism of the secondary lining trolley adopts a design in which the lower frame grid 23 is integrally connected to the support mechanisms on both sides and the formwork, which greatly simplifies the overall structure, reduces unnecessary components and connection points, and makes the entire support mechanism more concise and clear. The simplification of the support structure not only makes the manufacturing process easier and reduces production costs, but also makes it more convenient to operate and maintain in actual use. The support mechanism of the secondary lining trolley adopts a design in which the lower frame grid 23 is integrally connected to the support mechanisms on both sides and the formwork, which increases the passage area while ensuring strength, making it possible for large machinery to pass through the secondary lining trolley, facilitating the full mechanization of subsequent grouting and vibration operations, improving efficiency, and reducing labor costs.
