Description

Technical Field

[0001] The utility model relates to the technical field of full tailings filling, in particular to a sandwich-type full tailings filling wallboard. Background Art

[0002] In mining production, tailings filling is a crucial link. In order to effectively close the empty area, the application of filling retaining walls is particularly common. These retaining walls can be mainly divided into two categories: rigid retaining walls and flexible retaining walls according to their structure and performance. When the rigid retaining wall is under great pressure, it can maintain the stability of the structure and is not prone to safety hazards such as compression damage. However, an obvious defect of the rigid retaining wall is that it cannot complete the dehydration of the empty area tailings. The moisture in the tailings cannot be effectively discharged under the barrier of the rigid retaining wall, which has brought considerable troubles to the production efficiency and tailings treatment of the mine. Relatively speaking, the flexible retaining wall has shown its unique advantages. It can realize the dehydration function of the entire section, so that the moisture in the tailings can be discharged smoothly, thereby improving the utilization efficiency of the tailings and the overall production efficiency of the mine. However, the shortcomings of the flexible retaining wall are also obvious. Due to its relatively weak strength, it is often difficult to withstand the huge pressure of the filling mortar, and it is easy to have serious problems such as washout and leakage, which brings great safety hazards to mining production.

[0003] Therefore, how to achieve effective dehydration of tailings in the empty area while ensuring the strength of the filling retaining wall has become a major problem faced by the mining production field. To this end, we propose a sandwich-type full tailings filling wall panel. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a sandwich-type full tailings filling wall panel, comprising a concrete wall panel 1, on which a plurality of sandwich layers 2 are evenly arranged, the sandwich layer 2 comprising vertical steel bars 21 and horizontal steel bars 22, the vertical steel bars 21 and the horizontal steel bars 22 are connected to each other to form a steel cage, the left and right sides of the steel cage are respectively connected to the concrete wall panel 1, thereby forming a sandwich-type filling wall panel, the front and back sides of the steel cage are respectively provided with wire mesh 23, and crushed stones 24 are arranged in the steel cage, after the wall panel is fixedly placed in the corresponding position of the filling area, the crushed stones 24 are put into the space between the steel cage and the wire mesh 23 from the opening on the upper side, so as to realize the effective dehydration of the empty area tailings, while ensuring the strength of the filling retaining wall, it can quickly drain water through the sandwich layer 2, avoiding the long-term accumulation of water in the filling area and affecting the safety and environment of the filling area, ensuring the long-term normal use of the filling area, and improving the utilization efficiency of the tailings and the overall production efficiency of the mine.

[0021] According to a preferred technical solution, the sandwich layer 2 passes through the top and bottom ends of the concrete wall panel 1, and the transverse reinforcement 22 is fixedly connected to the reinforcement in the concrete wall panel 1, thereby ensuring the overall strength of the wall and the firmness of the sandwich layer 2, and preventing it from being washed away by accumulated water and mortar in the filling area.

[0022] A further preferred technical solution is that a partition 3 is provided at the connection between the inner side of the steel cage and the concrete wall panel 1. The partition 3 is arranged at a position perpendicular to the wire mesh 23. When the precast concrete wall 1 is cast, the concrete can be prevented from entering the steel cage and blocking the sandwich layer 2.

[0023] See also Figure 4-5 The utility model also provides another embodiment, which is substantially the same as the previous embodiment, except that the sandwich layer 2 is evenly arranged at the lower part or the middle and lower part of the side surface of the concrete wall panel 1, and the vertical steel bars 21 and the horizontal steel bars 22 are fixedly connected to the steel bars in the concrete wall panel 1. Although the drainage efficiency is reduced compared with the previous embodiment, the overall strength of the concrete wall panel 1 is improved by reducing the area of ​​the concrete wall panel 1 occupied by the sandwich layer 2, and the utility model is suitable for tailings filling areas that need to withstand greater pressure and less water accumulation.

[0024] According to a preferred technical solution, a plurality of fixing rings 25 for installing the wire mesh 23 are evenly arranged on the horizontal steel bars 22 provided with the wire mesh 23.

Preferably, the wire mesh on one side is fixed in advance, and then the concrete wall panel 1 is poured. Then, after the concrete wall panel 1 is fixed and placed in the corresponding position of the filling area, the gravel 24 is thrown in from the side where the wire mesh 23 is not installed, and then the wire mesh 24 is set through the fixing ring 25.

[0025] According to a further preferred technical solution, a shell 4 surrounded by four side panels is arranged inside the steel cage, and the shell 4 is used to isolate concrete. When the precast concrete wall 1 is poured, concrete can be prevented from entering the steel cage and clogging the sandwich layer 2.

[0026] Furthermore, a protective film 5 is provided at the two openings of the shell 4. The protective film 5 can be a plastic film or an ordinary tape, etc., which is mainly used to seal the two openings of the shell 4 to further prevent the concrete from entering the sandwich layer 2 during pouring. Before sealing, the shell 4 can be filled with plastic foam or sawdust and other materials to prevent the concrete from destroying the protective film 5 and entering the sandwich layer 2.
