Description

Technical Field

[0001] This invention relates to a building auxiliary equipment and its application, and in particular to a common rail transport and construction integrated formwork and its construction method for inclined shaft lining construction. Background Technology

[0002] In recent years, for example, the construction of pumped storage power stations has included large-scale inclined shafts. The straight sections of these shafts are typically hundreds of meters long, with an inclination of around 50 degrees. This makes lining construction extremely difficult and poses a very high safety risk. Existing, more advanced inclined shaft slipform technology typically uses separately constructed stepped passageways for personnel and material transportation. Material transport is usually done via simple tracks using winches, leading to difficulties in transporting personnel, steel reinforcement, and concrete, resulting in extremely high safety risks. For formwork lifting, a combination of winches or hydraulic jacks is often used, requiring additional excavation of the tunnel for anchor installation. This method is also unstable, leading to poor construction quality. Furthermore, the lifting system interferes with the installation of circumferential reinforcement, resulting in low construction efficiency and high costs. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide an integrated formwork and construction method for inclined shaft lining construction, which can solve the problems of personnel and material transportation such as steel bars and concrete, reduce the safety risks of inclined shaft lining construction, and provide assistance for external concrete and steel bar installation construction, improve construction efficiency and quality, and reduce construction costs.

[0004] This invention provides an integrated formwork for the common rail transport and construction of inclined shaft lining, comprising:

[0005] The truss track has at least two guide rails and is equipped with a sliding contact line fixing bracket mounting position, a rack mounting position, a concrete inlet chute mounting position, and a track support mounting position.

[0006] Truss track fixing frame, the truss track fixing frame is installed at the track support mounting position of the truss track;

[0007] A rail-mounted lifting transport vehicle includes a rail-mounted lifting transport vehicle frame, a rotary crane, drive guide shoes, a drive system, a car, and a cargo box. The rail-mounted lifting transport vehicle frame connects the rotary crane and multiple drive guide shoes, and connects the car and the cargo box. The drive guide shoes are equipped with rollers and are fitted onto the guide rails of the truss track. The guide shoes are connected to the drive system, and the drive system is connected to the control system. The sliding contact current collector of the control system is in contact with the sliding contact line laid along the truss track.

[0008] The concrete delivery system includes at least an upper aggregate hopper, a main concrete chute, and a buffer device chute. The main concrete chute is installed at the concrete delivery chute installation position on the truss track. The upper end of the main concrete chute is connected to the upper aggregate hopper. A set of buffer device chutes is connected to the main concrete chute at intervals along the pipeline.

[0009] The slipform formwork frame includes at least a template, a main operating platform, an auxiliary operating platform, guide shoes, one-way locking guide shoes, and a power and control system. The template is connected to the periphery of the main operating platform, the auxiliary operating platform is connected above the main operating platform, the main operating platform is connected to the guide shoes, and the guide shoes are equipped with rollers and are fitted onto the guide rails of the truss track. The traction device of the power and control system is connected at one end to the main operating platform and at the other end to the one-way locking guide shoe, which is equipped with rollers and is fitted onto the guide rails of the truss track. The auxiliary operating platform is also connected to another one-way locking guide shoe. The sliding contact current collector of the power and control system is in contact with the sliding contact line laid along the truss track.

[0010] In one embodiment, the buffer device chute of the concrete placement system is equipped with a movable gate located in the buffer device chute pipeline. The gate has holes corresponding to the pipeline. A push-pull device is provided to drive the gate to move its position. One end of the push-pull device is connected to the gate, and the other end is connected to the buffer device chute.

[0011] The construction method for the integrated formwork for the common rail transport and installation of the above-mentioned inclined shaft lining construction includes the following steps:

[0012] Pre-install the racks corresponding to each truss track section;

[0013] Erect a platform, connect the first section of the truss track to the platform, install at least one set of the truss track fixing frame, and lay out the sliding contact line;

[0014] Install the rail-mounted lifting transport vehicle and connect the power supply. Using the rail-mounted lifting transport vehicle and its own rotary crane, install the truss track and concrete placement system from top to bottom, lay the sliding contact line, install the truss track fixing frame, and tension the cable stays until the required length for the slipform frame assembly is met.

[0015] Install and temporarily fix the guide shoe of the slipform frame, install the main operating platform, install the template, install the power and control system, connect the power supply, install the one-way lock guide shoe, and install the auxiliary operating platform;

[0016] The power system was debugged, the bottom formwork of the straight section of the inclined shaft was erected and the first reinforcement was installed, and the concrete placement system was completed in preparation for the construction phase.

[0017] When the aforementioned integrated formwork for inclined shaft lining construction is applied, construction personnel and materials such as reinforcing steel are transported via a rail-mounted lifting transport vehicle supported by truss tracks.

No components in front of the slipform formwork affect the installation of circumferential reinforcing steel, significantly improving installation efficiency. The concrete placement system relies on track layout, ensuring stability and reliability. Furthermore, a gate is installed on the chute of the buffer device to buffer and prevent segregation. Moving the gate provides buffering and anti-segregation when the main pipeline is cut off; moving the gate also facilitates cleaning the concrete chute when the main pipeline is clear. This integrated formwork for inclined shaft lining construction, relying on truss tracks, integrates transportation and construction formwork into a single unit. It is simple and standardized to operate, has comprehensive safety facilities, and operates stably. It solves the transportation problems of personnel, reinforcing steel, and concrete in inclined shaft lining construction, reduces safety risks, improves construction efficiency and quality, and lowers construction costs, making it suitable for widespread application.

Detailed Implementation

[0031] 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.

[0032] like Figure 1 and Figure 2As shown, an embodiment of the integrated formwork for inclined shaft lining construction includes a truss track 1, a rail-mounted lifting transport vehicle 2, and a slipform formwork 3. In this embodiment, a platform is erected above the inclined shaft. Truss track fixing frames are connected at intervals below the truss track to provide support. Additionally, along the truss track direction, inclined cables are installed between adjacent truss track fixing frames. One end of the inclined cable is connected to the bottom of the upper truss track fixing frame, and the other end is connected to the top of the lower truss track fixing frame below the truss track. Components of a concrete placement system are connected below the truss track, used to inject concrete from the upper platform through the concrete placement system components to the pouring location, relying on the concrete's fluidity. The rail-mounted lifting transport vehicle 2 runs along the truss track 1, transporting construction personnel and reinforcing steel and other construction materials back and forth between the upper platform and the slipform formwork 3. The truss track 1 passes through the slipform formwork 3, which is guided by the truss track 1 and bears the construction load of its operation.

[0033] The following section will provide a clearer description of the details of each part, in conjunction with the accompanying drawings.

[0034] like Figure 3 The diagram shown is an isometric view of the connection between a section of truss track 1, rack 6, and sliding contact line fixing bracket 7 in one embodiment. Two circular tubes are welded to the frame at the top of the truss track 1; these two tubes serve as the rails of the truss track, guiding the rail-mounted lifting transport vehicle 2 and the sliding formwork 3. I-type and Y-type joints are respectively provided at the lower ends of the truss track 1, and bolt holes are provided on the crossbars at the upper ends, allowing multiple sections of the truss track to be connected end-to-end to form the required length. Rack 6 is connected to the crossbars at the top of the truss track. The rack mainly interacts with the drive device of the rail-mounted lifting transport vehicle 2, enabling the rail-mounted lifting transport vehicle 2 to run along the truss track 1, transporting construction personnel and materials. Two sliding contact line fixing brackets 7 are connected to the right side of the truss track 1. The sliding contact line fixing brackets 7 are used to fix the sliding contact line 8, providing construction power for the integrated rail transport and formwork for the inclined shaft lining construction.

[0035] like Figure 4 , Figure 5 , Figure 6As shown, the rail-mounted lifting transport vehicle 2 has a rail-mounted lifting transport vehicle frame 2a, with six sets of drive plate guide shoes 2b connected to the bottom of the frame, which are fitted onto the circular tube guide rails of the truss track 1. Each set of drive plate guide shoes is connected to a drive 2c. The gears of the drive 2c interact with the rack 6 installed above the truss track 1. Under the action of the control system, the rail-mounted lifting transport vehicle 2 is controlled to move along the truss track 1. The sides of the rail-mounted lifting transport vehicle frame 2a are connected to the car 2d and the cargo box 2e. The upper part of the rail-mounted lifting transport vehicle frame 2a is provided with an interface 2g for installing a rotary crane, which is used to lift heavy objects. The upper part of the rail-mounted lifting transport vehicle frame 2a is also provided with a steel bar anti-detachment storage bucket 2f. When transporting steel bars, the lower end of the steel bar is inserted into the steel bar anti-detachment storage bucket 2f to reduce the risk of the steel bar falling.

[0036] like Figure 7 , Figure 8 , Figure 9 As shown, the skeleton of the main operating platform 3a of the sliding formwork frame 3 is composed of multiple trusses 3a2 radiating outward from the central flange column 3a1. Between the two trusses 3a2 on both sides of the truss track 1, guide shoes and hydraulic cylinder fixing brackets 3a3 are connected. The guide shoes and hydraulic cylinder fixing brackets 3a3 are connected to guide shoes 3g that are sleeved on the circular tube guide rail of the truss track 1. A one-way locking guide shoe 3f is also connected to the auxiliary operating platform 3c near the truss track 1. These guide shoes, connected to the upper and lower guide shoes of the main operating platform 3a and the auxiliary operating platform 3c, guide the operation of the sliding formwork frame 3 and help stabilize it. The main operating platform is surrounded by a template 3. b, for concrete shaping; below the main operating platform 3a, there is a finishing platform 3e, used for finishing concrete surfaces, curing, and maintenance; on both sides of the auxiliary operating platform 3c, there is a stepped operating platform 3d, which together serve as the operating platform and access for construction personnel for concrete placement and rebar installation; at the guide shoe and hydraulic cylinder fixing bracket 3a3, one end of the cylinder body of the main hydraulic cylinder 3h is connected, and one end of the piston rod of the main hydraulic cylinder 3h is connected to another one-way locking guide shoe 3f. The one-way locking guide shoe 3f can be set to move only upward along the truss track 1 and not downward, to prevent the slipform frame from falling when the main hydraulic cylinder 3h changes steps.

[0037] like Figure 10 , Figure 11As shown, the upper aggregate hopper 5a of the concrete placement system is located between platforms 9. During construction, concrete is unloaded into the upper aggregate hopper 5a, flows into the main concrete chute 5c through the connecting joint pipe fitting 5b, flows downward through multiple sections of the main concrete chute 5c and the buffer device chute 5d, then turns at the elbow 5e and flows into the lower aggregate hopper 5h connected to the slipform frame 3 through the end concrete chute 5g. The end concrete chute 5g and the elbow 5e are connected by a rotating device 5f, allowing the end concrete chute 5g to... The concrete can rotate as the slipform frame 3 rises; the concrete flows into the lower aggregate hopper 5h connected to the slipform frame 3, and then the rotary concrete distributor 5i distributes the concrete into the concrete distribution plate 5j. The concrete distribution plate 5j has multiple compartments inside, and the bottom of the compartments has holes that are connected to the inlet chute 5k. By rotating the rotary concrete distributor 5i, the concrete is distributed to the corresponding compartments in the concrete distribution plate 5j. The concrete enters the formwork through the inlet chute. The construction personnel perform vibration operation on the main operating platform 3a of the slipform frame 3.

[0038] like Figure 12 and Figure 13 As shown, the buffer device chute 5d of the concrete placement system consists of an upper main pipe 5d1 and a lower main pipe 5d2. A gate 5d3 is connected between the pipes via a power-side connector 5d5 and a connector 5d6. The gate 5d3 has a hole corresponding to the main pipe. Moving the gate 5d3 causes the solid part to align with the main pipe, effectively cutting off the main pipe. Concrete flows in from the upper main pipe 5d1, impacts the gate 5d3, and accumulates within the upper main pipe 5d1. It then reaches the opening of the connecting branch pipe 5d4 and flows into the lower main pipe 5d2 via the connecting branch pipe 5d4. The concrete impacts the gate and accumulates to form a concrete pool, effectively buffering and preventing segregation, which is beneficial to concrete quality. During construction, the gate should be moved at regular intervals to open and close the main pipe, allowing the concrete accumulated at the gate to separate and flow downwards, reducing the likelihood of pipe blockage.

[0039] The aforementioned integrated rail transport and construction formwork for inclined shaft lining construction, including the rail-mounted lifting transport vehicle 2 that integrates the transportation of construction personnel and reinforcing steel materials, the slipform formwork 3 that serves as a scaffolding platform for concrete shaping and various construction operations, and the concrete placement system, all rely on rail operation and support. Furthermore, the various operating platforms of the slipform formwork 3 have rationally defined functional zones, effectively assisting in concrete and reinforcing steel construction. This integrated rail transport and construction formwork for inclined shaft lining construction is well-equipped, fully functional, and meets safety protection standards. It effectively solves the problems of transporting personnel, reinforcing steel materials, and concrete during inclined shaft lining construction, reduces safety risks, improves construction efficiency and quality, and lowers construction costs, making it suitable for widespread application.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
