Description

Technical Field

[0001] This utility model relates to a sealing operation device, specifically a sealing operation device for precast concrete arch slabs of tailings dam drainage wells, which is suitable for sealing tailings dam drainage shafts and daily inspection and maintenance operations. Background Technology

[0002] Tailings dam drainage shafts are important drainage facilities in tailings dams. The quality of the concrete precast arch slab sealing of the drainage shaft is related to the safe, environmentally friendly and stable operation of the tailings dam. If the sealing is done with water, the leakage of tailings water around the drainage shaft will be very serious. Defective sealing quality may cause accidents such as collapse, blockage, and tailings leakage of the drainage shaft.

[0003] Traditional methods for sealing flood discharge shafts involve a combination of mobile floating hulls and manual labor. Floodwater is discharged directly from the precast slabs. However, the floating hulls are difficult to move, the work platform sways significantly, and a large workforce is required. The labor intensity of moving the precast concrete slabs is high, resulting in low work efficiency. Furthermore, the operation carries significant safety risks such as falls from heights, drowning, collisions, and crushing. The sealing quality cannot be guaranteed, leading to severe water seepage and slurry leakage after the precast concrete arch slabs are sealed, posing a serious threat to the safe, environmentally friendly, and stable operation of the tailings dam. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a sealing device for precast concrete arch slabs in tailings dam drainage wells, comprising: a movable platform formed by splicing four floating platforms together with detachable connecting parts for the floating platforms, an outer guardrail of the platform, an inner guardrail of the platform, a small wireless remote-controlled hoisting device, a steel tugboat, and precast concrete arch slabs to be installed.

[0005] The floating platforms are all isosceles trapezoids with openings facing the top of the drainage shaft. The four floating platforms are spliced ​​together in pairs using detachable connectors to form a square platform with a central hole, which encloses the drainage shaft. Floating pontoons that meet buoyancy requirements are installed under the floating platforms. After rotating around the drainage shaft to the required position, the floating platforms are fixed around the perimeter of the shaft. Movable outer and inner guardrails are installed on the inner and outer sides of the floating platforms to ensure the safety of workers. A wireless remote-controlled hoisting device is installed on the movable platform for transporting the precast concrete arch slabs during installation.

[0006] When sealing the precast concrete arch slabs of the tailings dam drainage shaft, a steel tugboat is first used to transport the precast concrete arch slabs to the side of the movable platform. A small, wirelessly remote-controlled hoisting device is then used to move the precast concrete arch slabs onto the drainage shaft for installation. Afterward, concrete is used to smooth the gaps, and the device is used to seal the precast concrete arch slabs of the tailings dam drainage shaft. Drainage shafts typically have multiple openings; once one opening is sealed, the device can be easily moved to the next opening requiring sealing.

[0007] The beneficial effects of this utility model are:

[0008] (1) It can significantly improve work efficiency, reduce work safety risks, and reduce the intensity of work labor;

[0009] (2) In coordination with the drainage pump in the tailings pond, the water in the tailings pond does not pass directly through the top surface of the precast slab of the flood discharge well, so as to prevent water seepage or tailings leakage caused by water-sealing and effectively ensure the sealing quality of the precast slab.

[0010] (3) It can be used as a daily inspection platform for flood drainage shafts, and has good practical value. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding and application.

[0014] like Figure 1 As shown, a device for sealing precast concrete arch slabs in a tailings dam drainage well includes:

[0015] A movable platform is formed by splicing four floating platforms 1 together with floating platform detachable connectors 2. The movable platform has an outer guardrail 3, an inner guardrail 4, a flood discharge shaft 5, a small wireless remote-controlled hoisting device 6, a steel tugboat 7, and a precast concrete arch slab to be installed 8.

[0016] Four floating platforms 1 are prefabricated. Each floating platform 1 is an isosceles trapezoid with an opening at the top (facing the drainage shaft 5 after splicing). The opening is an arc, slightly larger than one-quarter of the circumference of the drainage shaft 5. The four floating platforms 1 are spliced ​​together in pairs via movable connecting units 2 to form a square with a central hole. The central hole encloses the drainage shaft 5. Floating pontoons meeting buoyancy requirements are installed under each floating platform 1 to support the platform's placement on the tailings pond surface. The floating platforms 1 can rotate around the drainage shaft 5 to the desired position and then be fixed around the perimeter of the drainage shaft 5. The floating platforms 1 are connected on-site using movable connecting units 2. For easy disassembly or relocation later; movable safety guardrails (outer guardrail 3 and inner guardrail 4) with a height of 1.2 meters are set on the inner and outer sides of the floating platform 1 to ensure the safety of water surface operations. The movable guardrails can be temporarily disassembled as needed for operation; a wireless remote control hoisting device 6 is set on the movable platform for the transportation operation during the installation of the precast concrete arch slab 8. The wireless remote control hoisting device 6 can realize the extension and rotation of the boom, wireless remote control operation, etc., making the operation more efficient and convenient. After the steel tugboat 7 transports the precast concrete arch slab 8 to the designated position, the wireless remote control hoisting device 6 is used to hoist the precast concrete arch slab 8 to be installed for installation.

[0017] Preferably, the floating platform 1 is a patterned steel plate platform, the wireless remote control hoisting device 6 is a small wireless remote control hoisting device, and the floating platform detachable connector 2 is a detachable connector that can be easily connected and disassembled as needed.

[0018] Using this operating platform to seal precast concrete arch slabs in tailings dam drainage shafts previously required 10 people (6 to lift the precast slabs, each weighing approximately 320 kg, 2 to support and seal the surface, and 2 to fix and move the floating platform). With this device, only 3 people are needed to complete the sealing of the precast concrete slabs (1 to operate the wireless remote-controlled hoisting device, 1 to support and seal the surface, and 1 to direct and assist). The time to seal a single precast concrete arch slab is reduced from 30 minutes to less than 10 minutes, significantly improving work efficiency, reducing the number of workers, lowering safety risks associated with personnel handling and floating platform movement, and reducing labor intensity. Furthermore, the mobile platform can serve as a daily inspection platform for drainage shafts when not used for sealing precast concrete arch slabs. After use, the device can be moved to the next drainage shaft for repeated installation, demonstrating significant practical and recycling value.

[0019] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, various changes in form and detail can be made to it according to actual needs when used in the field, without departing from the scope defined by the claims of this utility model.
