Description

Technical Field

[0001] This utility model relates to the technical field of permeable dam structure for low tailings ponds, specifically to a dam structure that lowers the phreatic line of a permeable dam for a tailings pond. Background Technology

[0002] In the use of permeable tailings dams, it is necessary to lower the phreatic line inside the dam body. Therefore, it is necessary to lower the dam body structure of the permeable tailings dam body.

[0003] For example, the patent publication number CN204780779U describes a dam structure that effectively reduces the phreatic line of a tailings dam. This structure uses a suspended water-stop curtain installed on the inner slope of the dam body. The suspended water-stop curtain consists of two rows of jet grouting piles, which are staggered in the direction parallel to the dam body. Each jet grouting pile is perpendicular to the horizontal plane.

[0004] However, in actual use, as the tailings dam structure is continuously built up, the suspended cutoff curtains also increase in height. When controlling the phreatic line, water inside the dam may seep between the two suspended cutoff curtains. This fails to effectively lower the phreatic line and increases the risk of dam collapse. Therefore, the applicant proposes a dam structure that lowers the phreatic line of the tailings dam. Utility Model Content

[0005] The purpose of this invention is to provide a dam structure that lowers the phreatic line of a tailings dam, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dam structure for reducing the phreatic line of a tailings dam, comprising an initial tailings dam, wherein the outer wall of the initial tailings dam is in contact with an anti-seepage mechanism, the anti-seepage mechanism comprising a middle dam, the outer wall of the middle dam being in contact with an anti-seepage frame, a water storage tank being provided at the top of the middle dam, a baffle plate being in contact with one side of the water storage tank of the middle dam, an inclined panel being fixed to the bottom side of the baffle plate, the inclined surface at the bottom of the inclined panel being in contact with one side of the middle dam, a water pipe being connected to one side of the inner wall of the anti-seepage frame at one end of the middle dam, a diversion pipe being fixed to the drainage end of the water pipe, an opening being provided at the top of the diversion pipe, a seepage plate being fixed to the inner wall of the opening at the top of the diversion pipe, and drainage pipes being fixed to both sides of the drainage end of the diversion pipe.

[0007] Preferably, one end of the seepage prevention mechanism is connected to a reinforcement mechanism, and the top of one end of the initial dam of the tailings dam is in contact with the bottom of one end of the reinforcement mechanism.

[0008] Preferably, the inclined surface at the top of the inclined panel contacts a top dam, the bottom of the drainage pipe contacts a bottom dam, both the top dam and the bottom dam are located inside the seepage prevention frame and are in contact with the inner wall of the seepage prevention frame, the inlet end of the water pipe is sealed with a filter pipe, the inlet end of the filter pipe is sealed with an inlet pipe, and several water valves are fixed on one side of the inlet pipe.

[0009] Preferably, the top of the drainage pipe is in contact with the bottom of the intermediate dam, the angle between the drainage pipe and the intermediate dam is between 20-30°, the angle between the baffle plate and the top of the intermediate dam is between 120-150°, and the horizontal angle of the inclined panel is between 40-60°.

[0010] Preferably, the reinforcement mechanism includes a fixing plate, a plurality of connecting rods are fixed on one side of the fixing plate, and a load-bearing rod is fixed on one side of each connecting rod.

[0011] Preferably, one side of the fixed plate is in contact with one side of the top dam in the seepage prevention mechanism, one end of several connecting rods passes through one side of the top dam and is fixed to the top inclined surface of the inclined panel, and one end of several load-bearing rods is in contact with one side of the initial dam of the tailings dam.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The dam structure that lowers the phreatic line of the tailings dam features a seepage prevention mechanism, including baffles and inclined panels. When lowering the phreatic line inside the dam, the baffles and inclined panels prevent water from seeping towards the top of the dam, thus improving the efficiency of lowering the phreatic line and reducing the risk of dam collapse.

[0014] Meanwhile, the seepage prevention mechanism is also equipped with diversion pipes and seepage plates. When the seepage line inside the dam is lowered, the seeping water will sink downwards due to gravity. When it comes into contact with the seepage plate, the seeping water will flow into the diversion pipe and be discharged, which further improves the efficiency of lowering the seepage line and reduces the risk of dam collapse.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] During the construction of tailings dams, in order to improve the safety of the tailings dams, it is necessary to lower the phreatic line of the tailings dam permeable dam. Therefore, it is necessary to lower the dam structure of the tailings dam permeable dam body. In the actual use of most traditional tailings dam permeable dam structures, with the continuous accumulation of tailings dams in the later stages, water seepage may occur in some areas of the device. At this time, the device cannot effectively drain the seepage water inside the dam body. Under long-term use, the risk of dam collapse increases. Therefore, the applicant proposes a dam structure that lowers the phreatic line of the tailings dam permeable dam body.

[0022] like Figures 1-4As shown, this utility model provides a technical solution: a dam structure for reducing the phreatic line of a tailings dam, including an initial tailings dam 1. The outer wall of the initial tailings dam 1 is in contact with an anti-seepage mechanism 2. The anti-seepage mechanism 2 includes a middle dam 201, the outer wall of which is in contact with an anti-seepage frame 202. A water storage tank is provided at the top of the middle dam 201. A baffle plate 203 is in contact with one side of the water storage tank. An inclined plate 204 is fixed to the bottom side of the baffle plate 203. The inclined surface at the bottom of the inclined plate 204 contacts one side of the middle dam 201. A water pipe 205 is connected to the inner wall of the anti-seepage frame 202 at one end of the middle dam 201. A drainage pipe 206 is fixed to the bottom end of the water pipe 205. An opening is provided at the top of the drainage pipe 206. A seepage plate 207 is fixed to the inner wall of the opening at the top of the drainage pipe 206. Drainage pipes are fixed to both sides of the drainage end of the drainage pipe 206. Pipe 208, one end of the seepage prevention mechanism 2 is clamped to the reinforcement mechanism 3, the top of one end of the initial dam 1 of the tailings dam is in contact with the bottom of one end of the reinforcement mechanism 3, the inclined surface of the top of the inclined panel 204 is in contact with the top dam 209, the bottom of the diversion pipe 206 is in contact with the bottom dam 210, the top dam 209 and the bottom dam 210 are both located inside the seepage prevention frame 202 and are in contact with the inner wall of the seepage prevention frame 202, the inlet end of the water pipe 205 is sealed and clamped to the filter pipe 211. The inlet end of the filter pipe 211 is sealed with an inlet pipe 212. Several water valves 213 are fixed on one side of the inlet pipe 212. The top of the diversion pipe 206 is in contact with the bottom of the middle dam 201. The angle between the diversion pipe 206 and the middle dam 201 is between 20-30°. The angle between the baffle plate 203 and the top of the middle dam 201 is between 120-150°. The horizontal angle of the inclined plate 204 is between 40-60°.

[0023] It should be noted that during the use of the tailings dam, when water seeps into the water storage tank at the top of the middle dam 201, the seeping water will not come into contact with the dry beach of the top dam 209 due to the baffle plate 203. Subsequently, as the water continues to seep in, the inclined plate 204 will also restrict the water to below the phreatic line. Finally, the water will seep to the bottom of the middle dam 201 and enter the drainage pipe 206 through the seepage plate 207, and then be discharged from the drainage pipe 206. At this time, the phreatic line inside the dam body will be lowered due to the discharge of water. When there is too much water in the water storage tank at the top of the middle dam 201, the water valve 213 will be activated. At this time, the accumulated water will enter the drain pipe 208 through the filter pipe 211, and then flow from the drain pipe 208 into the drainage pipe 206 until it is finally discharged.

[0024] like Figure 4As shown, this utility model provides a technical solution: a dam structure that lowers the phreatic line of a tailings dam, including a reinforcement mechanism 3. The reinforcement mechanism 3 includes a fixing plate 301, with several connecting rods 302 fixed on one side of the fixing plate 301, and load-bearing rods 303 fixed on one side of the connecting rods 302. One side of the fixing plate 301 is in contact with one side of the top dam 209 in the seepage prevention mechanism 2. One end of several connecting rods 302 passes through one side of the top dam 209 and is fixed to the top inclined surface of the inclined panel 204. One end of several load-bearing rods 303 is in contact with one side of the initial dam 1 of the tailings dam.

[0025] It should be noted that when the tailings dam is squeezed and shaken due to vibration or other factors, the fixing plate 301 will limit the top dam 209 due to the connecting rod 302, and the force will be offset by the load-bearing rod 303, thereby increasing the stability of the dam body.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
