Description

Technical Field

[0001] This invention belongs to the field of tunnel construction technology, specifically relating to an intelligent device for slipform construction of inverted arch filling. Background Technology

[0002] Currently, the concrete pouring for the arch ring in invert construction is difficult, and the invert concrete and infill concrete must be poured separately, resulting in a long construction period. The excessively long excavation time for the invert also leads to a prolonged period without the tunnel support being fully enclosed, posing significant safety risks.

[0003] To address the issues of separate pouring of invert concrete and invert filling concrete in existing technologies, which leads to longer construction periods and greater safety risks, it is necessary to improve the structure of the slipform construction for invert filling, thereby resolving the current technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent device for slipform construction of invert arch filling. The invert arch and invert arch filling are constructed continuously and without interruption using slipform construction technology, ensuring rapid formation of the secondary lining of the tunnel and the formation of a stable structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent device for slipform construction of inverted arch filling, comprising: Pier; The first moving component is disposed on the bottom surface at both ends of the trestle and is used to move the trestle. The second moving component is disposed on the bottom surface of the middle section of the trestle; The inverted arch formwork is movably connected to the second movable component; A concrete chute, with its two ends connected to the trestle bridge and the invert arch formwork, respectively; and The control box is fixed to one end of the trestle, and the first moving component and the second moving component are both electrically connected to the control box.

[0006] By adopting the above technical solution, the invert arch reinforcement, invert arch concrete, and invert arch filling concrete are continuously and uninterruptedly constructed using slipform construction technology, ensuring rapid formation of the tunnel secondary lining and the formation of a stable structure. The invert arch formwork divides the area at the bottom of the trestle bridge into an invert arch reinforcement construction area, an invert arch concrete pouring area, and an invert arch filling pouring area. The invert arch concrete pouring area has been completed, and the invert arch reinforcement construction has been completed in the invert arch concrete pouring area. Therefore, with the equipment of this application, reinforcement workers, formwork workers, invert arch concrete pouring workers, and invert arch filling concrete pouring workers can work simultaneously. After the invert arch reinforcement construction is completed, the formwork workers wait for the concrete in the invert arch concrete pouring area to be poured and reach a certain strength. Then, the formwork workers move the entire equipment using the first moving component until the invert arch formwork is located at the top of the invert arch reinforcement construction area. The reinforcement workers then begin construction of a new section of invert arch reinforcement. After adjusting the formwork position, the formwork workers pour the invert arch concrete, and the invert arch filling concrete can then be poured in the invert arch concrete pouring area that was previously in use. Therefore, by using slipform construction technology to continuously and uninterruptedly construct the invert arch reinforcement, invert arch concrete, and invert arch filling concrete, the secondary lining of the tunnel can be rapidly formed, resulting in a stable structure.

[0007] To better realize the present invention, two sets of railings are symmetrically provided on the top surface of the trestle along the extension direction of the trestle.

[0008] By adopting the above technical solutions, safety protection can be provided for construction workers to prevent them from accidentally falling and causing safety accidents.

[0009] To better implement the present invention, the first moving component includes a first crossbeam, the trestle is fixed to the top surface of the first crossbeam, at least two synchronously lifting first hydraulic lifting rods are connected to the bottom of the first crossbeam, the bottom of the two first hydraulic lifting rods are connected to a second crossbeam, and the two ends of the second crossbeam are connected to traveling wheels.

[0010] By adopting the above technical solution, the intelligent walking wheels drive the second crossbeam to move, which in turn sequentially drives the first hydraulic lifting rod, the first crossbeam, the trestle bridge, and the invert arch formwork to move, thereby quickly changing the work area and proceeding to the next construction process. The height of the trestle bridge can be adjusted by raising and lowering the first hydraulic lifting rod, avoiding damage to the poured concrete during movement and accommodating concrete of different thicknesses, ensuring the flatness of the invert arch filling concrete after pouring. To better realize the present invention, the walking wheel is an intelligent machine track walking wheel driven by an electric motor.

[0011] By adopting the above technical solutions, the intelligent machine's tracked wheels significantly improve construction efficiency and continuity. Traditional slipform construction typically requires the laying of tracks, while the tracked wheels allow the equipment to move directly on the initial support ground or already filled concrete, saving time and manpower spent on track laying, dismantling, and transportation. Motor drive enables stepless speed regulation, forward and reverse movement, and precise turning. Equipment positioning, relocation, and fine-tuning are extremely fast, significantly shortening process intervals and achieving near-continuous cyclical operations. No additional traction equipment (such as winches or hydraulic jacking systems) is required; the equipment is self-contained, simplifying site layout and management. Construction quality and precision are significantly improved. The large track contact area results in low pressure and smooth movement, minimizing disturbance to newly poured concrete or soft foundations, effectively preventing surface damage or internal defects caused by equipment movement. Combined with an intelligent control system (such as GPS, total station, or laser guidance), the motor drive can achieve centimeter-level or even millimeter-level walking accuracy. The equipment can move automatically according to the design line, ensuring that the elevation, centerline and slope of the invert arch filling are accurate and correct, thus improving the structural dimensional accuracy.

[0012] To better realize the present invention, the second moving component includes a U-shaped limiting slider, and the side of the trestle is provided with a limiting slide rail for the U-shaped limiting slider to slide.

[0013] By adopting the above technical solution, the U-shaped limit slider slides along the limit rail, which improves the stability of equipment movement. At the same time, it can increase the force-bearing area of ​​the slider, improve its resistance strength, and ensure construction safety.

[0014] To better realize the present invention, the bottom of the U-shaped limiting slider is connected to a second hydraulic lifting rod and a template traveling motor. The output end of the template traveling motor is connected to a gear. The bottom surface of the trestle is provided with a gear rail meshing with the gear. The bottom of the second hydraulic lifting rod is connected to a support frame. The arch template is fixedly connected to the bottom end of the support frame.

[0015] By adopting the above technical solution, when the tunnel excavation progress cannot keep up with the invert arch construction progress, causing the trestle bridge to be temporarily unable to move forward, the second moving component can be used to move the invert arch formwork to the invert arch reinforcement construction area. This allows for the timely pouring of invert arch concrete and invert arch filling concrete in the completed reinforcement construction area. Specifically, the formwork traveling motor drives the gears to rotate along the meshing gear rails, thereby driving the U-shaped limit slider to slide along the limit rails, ultimately moving the invert arch formwork through the support frame. Before pouring, the rising and falling of the invert arch formwork can be controlled by the second hydraulic lifting rod, facilitating rapid formwork construction and invert arch concrete pouring, improving construction efficiency and reducing the risk of accidents.

[0016] To better realize the present invention, the inverted arch template includes an inverted arch top mold, which is a concave arc-shaped structure, and the concave surface of the inverted arch top mold is fixedly connected to the bottom end of the support frame.

[0017] By adopting the above technical solution, the invert arch is the main shaping and stress-bearing surface. The invert arch concrete is poured directly through the invert arch top formwork with a circular arc structure, avoiding the waste of time assembling formwork.

[0018] To better realize the present invention, the inverted arch template further includes an inverted arch end mold, which is fixedly connected to one end of the inverted arch top mold and located on the convex surface of the inverted arch top mold. The inverted arch end mold is a segment of an annular structure concentric with the inverted arch top mold.

[0019] By adopting the above technical solution, the invert end formwork is a structure that acts as a plug in the invert concrete pouring area to prevent concrete from flowing out. After the invert formwork is adjusted, the invert end formwork, the invert top formwork, and the end face edge of the previous section of invert concrete formwork together form the pouring space for the invert concrete.

[0020] To better realize the present invention, the invert arch template further includes an invert arch filling end mold, which is fixedly connected to the other end of the invert arch top mold and located on the concave surface of the invert arch top mold. The invert arch filling end mold is part of a circular plate-shaped structure concentric with the invert arch top mold.

[0021] By adopting the above technical solution, the invert arch filling end formwork is a structure that acts as a plug in the invert arch filling concrete pouring area. After the invert arch formwork is adjusted, the invert arch filling end formwork and the end face of the previous section of invert arch filling concrete form the pouring space for the invert arch filling concrete.

[0022] Beneficial effects: This application utilizes a slipform construction process for continuous and uninterrupted construction of the invert arch reinforcement, invert arch concrete, and invert arch filling concrete, ensuring rapid formation of the tunnel secondary lining and the creation of a stable structure. Specifically, the invert arch formwork divides the area at the bottom of the trestle bridge into an invert arch reinforcement construction zone G, an invert arch concrete pouring zone H, and an invert arch filling pouring zone T. The invert arch concrete pouring zone T has already been completed, and the invert arch reinforcement construction has been completed in the invert arch concrete pouring zone H. Therefore, using the equipment of this application, reinforcement workers, formwork workers, invert arch concrete pouring workers, and invert arch filling concrete pouring workers can work simultaneously. After the invert arch reinforcement construction is completed, once the concrete in the invert arch concrete pouring zone H has been poured and reached a certain strength, the formwork worker moves the entire equipment using the first moving component until the invert arch formwork is positioned at the top of the invert arch reinforcement construction zone G. The reinforcement workers then begin construction of a new section of invert arch reinforcement. After adjusting the formwork position, the formwork worker pours the invert arch concrete, and the invert arch filling concrete can then be poured in the previously moved invert arch concrete pouring zone H.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example like Figure 1 - Figure 5 As shown, an intelligent device for slipform construction of inverted arch filling includes: Pier 1; The first moving component 2 is disposed on the bottom surface at both ends of the trestle 1 and is used to move the trestle 1. The second moving component 3 is located on the bottom surface of the middle section of the trestle 1; The inverted arch formwork 4 is movably connected to the second movable component 3; Concrete chute 5, with its two ends connected to trestle 1 and invert arch formwork 4 respectively; and The control box 6 is fixed to one end of the trestle 1, and the first moving component 2 and the second moving component 3 are both electrically connected to the control box 6.

[0027] The working principle of this invention can be summarized as follows: like Figure 5 As shown, the invert arch formwork 4 divides the area at the bottom of the trestle 1 into the invert arch reinforcement construction area G, the invert arch concrete pouring area H, and the invert arch filling pouring area T. The invert arch concrete pouring has been completed in the invert arch filling pouring area T, and the invert arch reinforcement construction has been completed in the invert arch concrete pouring area H. Therefore, with the equipment of this application, the reinforcement workers, formwork workers, invert arch concrete pouring workers, and invert arch filling concrete pouring workers can carry out construction simultaneously.

[0028] After the invert arch reinforcement construction is completed, once the concrete in the invert arch concrete pouring area H has been poured and reached a certain strength, the formwork workers use the first moving component 2 to move the entire equipment until the invert arch formwork 4 is located at the top of the invert arch reinforcement construction area G. The reinforcement workers then begin construction of a new section of invert arch reinforcement. After adjusting the formwork position, the formwork workers pour the invert arch concrete. Meanwhile, the invert arch concrete pouring area H, which was previously in use, can then be used for pouring the invert arch filling concrete. Thus, by using slipform construction technology for continuous and uninterrupted construction of the invert arch reinforcement, invert arch concrete, and invert arch filling concrete, the rapid formation of the tunnel secondary lining and the establishment of a stable structure can be ensured.

[0029] Preferably, two sets of railings 11 are symmetrically provided on the top surface of the trestle bridge 1 along the extension direction of the trestle bridge 1 to provide safety protection for construction workers and prevent them from accidentally falling and causing safety accidents.

[0030] Preferably, the first moving component 2 includes a first crossbeam 21, a trestle 1 fixed to the top surface of the first crossbeam 21, at least two synchronously lifting first hydraulic lifting rods 22 connected to the bottom of the first crossbeam 21, a second crossbeam 23 connected to the bottom of the two first hydraulic lifting rods 22, and walking wheels 24 connected to both ends of the second crossbeam 23. The walking wheels 24 are motor-driven intelligent machine tracked walking wheels 24. The intelligent machine tracked walking wheels greatly improve construction efficiency and continuity. Traditional slipform usually requires the laying of tracks, while the tracked walking wheels allow the equipment to move directly on the initial support ground or the already filled concrete, saving the time and manpower for track laying, dismantling, and transportation. The motor drive can achieve stepless speed change, forward, backward, and precise turning, and the equipment positioning, transfer, and fine-tuning speeds are extremely fast, greatly shortening the process interval and achieving near-continuous cyclical operation. No additional traction equipment (such as winches or hydraulic jacking systems) is required; the equipment is self-contained, simplifying site layout and management. Significantly improving construction quality and precision, the tracked vehicles have a large ground contact area, low pressure, and stable movement, minimizing disturbance to newly poured concrete or soft foundations, effectively preventing surface damage or internal defects in the concrete caused by equipment movement. Combined with an intelligent control system (such as GPS, total station, or laser guidance), the motor drive achieves centimeter-level or even millimeter-level walking accuracy. The equipment can automatically move strictly according to the design alignment, ensuring accurate elevation, centerline, and slope of the invert arch filling, improving structural dimensional accuracy. The intelligent walking wheels 24 drive the second crossbeam 23, which in turn sequentially drives the first hydraulic lifting rod 22, the first crossbeam 21, the trestle bridge 1, and the invert arch formwork 4, allowing for rapid changes in work areas and the commencement of the next construction process. The height of the trestle bridge 1 can be adjusted by raising and lowering the first hydraulic lifting rod 22, avoiding damage to the poured concrete during movement and accommodating concrete of varying thicknesses, ensuring the flatness of the invert arch filling concrete after pouring.

[0031] Preferably, the second moving component 3 includes a U-shaped limiting slider 31, and the side of the trestle 1 is provided with a limiting rail 32 for the U-shaped limiting slider 31 to slide.

The output end of the template traveling motor 34 is connected to a gear 36. The bottom surface of the trestle 1 is provided with a gear rail 37 meshing with the gear 36. The bottom of the second hydraulic lifting rod 33 is connected to a support frame 35, and the invert arch template 4 is fixedly connected to the bottom end of the support frame 35. When the tunnel excavation progress does not keep up with the invert arch construction progress, causing the trestle 1 to be temporarily unable to move forward, the second moving component 3 can drive the invert arch template 4 to the invert arch reinforcement construction area G, and the invert arch concrete and invert arch filling concrete can be poured in a timely manner in the completed invert arch reinforcement construction area G. Specifically, the template traveling motor 34 drives the gear 36 to rotate and move along the gear rail 37, thereby driving the U-shaped limiting slider 31 to slide along the limiting rail 32, and finally driving the invert arch template 4 to move through the support frame 35. Before pouring, the rise and fall of the invert arch formwork 4 can be controlled by the second hydraulic lifting rod 33, which facilitates the quick completion of formwork construction and the pouring of invert arch concrete, improves construction efficiency and reduces the risk of accidents.

[0032] Preferably, the invert arch formwork 4 includes an invert arch top mold 41, which is a concave arc-shaped structure. The concave surface of the invert arch top mold 41 is fixedly connected to the bottom end of the support frame 35. The invert arch is the main shaping and load-bearing surface. The invert arch concrete is poured directly through the arc-shaped invert arch top mold 41, avoiding the waste of time assembling formwork.

[0033] Preferably, the invert arch formwork 4 further includes an invert arch end mold 42, which is fixedly connected to one end of the invert arch top mold 41 and located on the convex surface of the invert arch top mold 41. The invert arch end mold 42 is a segment of a ring structure concentric with the invert arch top mold 41. The invert arch end mold 42 acts as a plug for the invert arch concrete pouring area H, preventing concrete from flowing out. After the invert arch formwork 4 is adjusted, the invert arch end mold 42, the invert arch top mold 41, and the end face edge of the previous section of invert arch concrete form the pouring space for the invert arch concrete.

[0034] Preferably, the invert arch formwork 4 further includes an invert arch filling end mold 43, which is fixedly connected to the other end of the invert arch top mold 41 and located on the concave surface of the invert arch top mold 41. The invert arch filling end mold 43 is part of a circular plate-shaped structure concentric with the invert arch top mold 41. The invert arch filling end mold 43 is a structure that acts as a plug for the invert arch filling concrete pouring area. After the invert arch formwork 4 is adjusted, the invert arch filling end mold 43 and the end face of the previous section of invert arch filling concrete form the pouring space for the invert arch filling concrete.
