Description

Technical Field

[0001] This utility model belongs to the field of mining tailings technology, specifically relating to a device for sealing the drainage well of a tailings dam. Background Technology

[0002] Mines, as crucial bases for resource extraction, have always bore the heavy responsibility of supplying metals, ores, and mineral products needed by various industries. However, tailings are a necessary and important byproduct of mineral processing, and tailings treatment relies on tailings dams. Tailings dams are facilities primarily built to store tailings or other industrial waste discharged after ore beneficiation in metal or non-metal mines. They are formed by damming valleys or enclosing land, possessing high potential energy. Their safety technology and management are indispensable parts of mine production, as dam failures can lead to significant personal injury and property damage. Therefore, the establishment of tailings dams aims to protect the environment, conserve resources, and ensure safe mine production. Tailings dams are also important environmental protection and safety facilities in mine construction, and the effectiveness of their safety technology and management directly relates to the sustainable development of mine production.

[0003] Tailings dams mainly consist of a tailings storage system, a flood discharge system, and a return water system. The tailings flood discharge system is an essential part of the tailings treatment process. The tailings dam drainage system includes intercepting ditches, spillways, flood discharge wells, drainage pipes, and drainage tunnels. Its main functions are to prevent seepage damage downstream of the dam site, prevent downstream marshland formation, lower the phreatic line of the dam body, and increase the stability of the dam body. The flood discharge wells within the dam play a crucial role, introducing clarified water into the downstream return water pumping station or directly pumping clarified water to a high-level water tank for the recovery and recycling of tailings water. The tailings water treatment system treats tailings water that does not meet the standards for reuse or discharge, ensuring that it meets the standards. Currently, traditional flood discharge wells often suffer from problems such as low efficiency, difficulty in sealing, and increased safety risks. Summary of the Invention

Multiple arc-shaped arch plates are installed from bottom to top between two adjacent U-shaped slots on any two adjacent longitudinal columns of the drainage wells. The U-shaped slots are sealed to the longitudinal column of the drainage well, the arc-shaped arch plates are sealed to the U-shaped slots, and the two adjacent arc-shaped arch plates are sealed to the top and bottom.

[0007] Preferably, there is a space between the two U-shaped slots on any longitudinal column of the flood discharge well, and a clamping shaft passes through the space between the two U-shaped slots on the longitudinal column of the flood discharge well and enters the longitudinal column of the flood discharge well to press and fix the two U-shaped slots.

[0008] Preferably, multiple clamping shafts are provided on each longitudinal column of the drainage well.

[0009] Preferably, it also includes a limiting shaft that passes through the U-shaped groove from the outside to the inside and limits and fixes the arc-shaped arch plate in the U-shaped groove, with at least one limiting shaft on each side of each arc-shaped arch plate.

[0010] Preferably, the contact surface between the U-shaped groove and the arc-shaped arch plate is provided with a first sealing body.

[0011] Preferably, the inner wall of the arc-shaped arch plate is provided with a second sealing body.

[0012] Preferably, the upper and lower edges of the arc-shaped arch plate are respectively provided with a water-stopping protrusion and a water-stopping groove with matching structures.
