Description

Technical Field

[0001] This utility model belongs to the field of goaf filling technology and relates to an underground filling wall. Background Technology

[0002] Mines using the infill mining method must seal and backfill the goaf after ore extraction. Currently, goaf sealing is mostly done by constructing backfill walls, with clay bricks or synthetic bricks made from industrial waste such as fly ash as the main materials. This method not only involves a large amount of masonry work, low construction efficiency, and high labor intensity, but also incurs high costs and a long construction period. Utility Model Content

[0003] The purpose of this utility model is to address the problem that using brick masonry to seal goaf areas in the background technology is time-consuming and labor-intensive, and to provide an underground filling plate wall.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A downhole filling wall includes a wall composed of multiple wall modules spliced ​​together. Each wall module includes an outer metal mesh, and a concrete metal mesh baffle is provided on one side of the outer metal mesh. The outer metal mesh and the concrete metal mesh baffle are provided with a concrete layer. Multiple connecting rods are provided in the concrete layer. One end of each connecting rod is fixed to the outer metal mesh and the other end is fixed to the concrete metal mesh baffle.

[0006] Furthermore, the outer metal mesh and the concrete metal mesh baffle are arranged parallel to each other.

[0007] Furthermore, the connecting rod and the metal mesh are arranged perpendicular to each other.

[0008] Furthermore, the concrete metal mesh baffle includes an inner metal mesh sheet and a denser metal mesh sheet.

[0009] Furthermore, geotextile is provided between the inner metal mesh and the encrypted metal mesh.

[0010] The beneficial effects of this utility model are as follows: by splicing multiple wall modules consisting of outer metal mesh panels and concrete metal mesh baffles on site to form a wall, the goaf can be sealed. Compared with brick masonry, this method is more convenient, faster, and saves time and effort. It can be applied to sealing goaf openings of different sizes, structural testing, and is low in cost.

[0013] The present invention will now be described in detail with reference to the accompanying drawings:

[0014] like Figure 1 As shown, an underground filling wall includes a wall composed of multiple wall modules spliced ​​together. Specifically, the wall modules can be spliced ​​together by welding. The number of wall modules can be selected according to the size of the goaf sealing area. Each wall module includes an outer metal mesh 1. A concrete metal mesh baffle 2 is provided on one side of the outer metal mesh 1, which is parallel to the outer metal mesh 1. The concrete metal mesh baffle 2 includes an inner metal mesh 201 and a denser metal mesh 202, and geotextile 3 is provided between the inner metal mesh 201 and the denser metal mesh 202. The inner metal mesh 201 and the dense metal mesh 202 can be connected by binding with steel wire rope. The concrete metal mesh baffle 2 is formed by the two layers of metal mesh and geotextile, which can ensure sufficient strength. A concrete layer 4 is provided between the outer metal mesh 1 and the concrete metal mesh baffle 2. Multiple connecting rods 5 are provided in the concrete layer 4, which are perpendicular to the outer metal mesh 1. The connecting rods 5 can be made of steel bars. One end of the connecting rod 5 is fixed to the outer metal mesh 1 and the other end is fixed to the concrete metal mesh baffle 2. Specifically, it can be fixed by welding.

[0015] The method of using this utility model is as follows:

[0016] When sealing the entrance to a goaf, the wall modules are first assembled on-site in the sealing area. A corresponding number of outer metal mesh panels 1 and concrete metal mesh baffles 2 are selected. Then, connecting rods 5 are welded between the outer metal mesh panels 1 and the concrete metal mesh baffles 2. After welding, adjacent outer metal mesh panels 1 are welded together, and simultaneously, the concrete metal mesh baffles 2 are welded together. After welding, they are installed at the corresponding positions at the entrance, with the outer metal mesh panels 1 located outside the entrance and the concrete metal mesh baffles 2 located inside the entrance. Then, the outer metal mesh panels near the top and sides of the entrance are... The metal mesh 1 and the concrete metal mesh baffle 2 are anchored to the top and sides of the opening using hook anchor rods. Finally, a wet spraying machine is used to spray concrete from one side of the outer metal mesh 1 into the space between the outer metal mesh 1 and the concrete metal mesh baffle 2, thus forming a concrete layer between the outer metal mesh 1 and the concrete metal mesh baffle 2. Due to the installation of geotextile 3, concrete seepage from the concrete metal mesh baffle 2 can be prevented during concrete spraying, thus avoiding waste. At the same time, the water in the concrete can be drained, thereby completing the installation of the panel wall. The whole process is quick, convenient, time-saving and labor-saving.
