Description

Technical field:

[0001] The utility model belongs to the field of mine goaf filling, in particular to a mine goaf filling retaining wall. Background technology:

[0002] Goafs are "holes" created beneath the surface by human excavation or natural geological movements. The existence of goafs poses great safety issues to mine production, as both personnel and mechanical equipment may fall into the goaf and be injured.

[0003] In order to avoid the hazards caused by goafs, commonly used treatment methods include pouring and filling method, crossing / spanning method, masonry method, excavation and backfill method, dynamic tamping method, preloading preloading method, etc. Among them, the pouring and filling method is the most widely used and suitable for various types of goaf management. Taking the pouring and filling method as an example, during filling, a prefabricated retaining wall is required to block the filling slurry so that the filling slurry is isolated in the goaf to form a filling body. Existing filling retaining walls are generally artificially built brick walls. Although this method has low cost investment, it takes a long time to build the brick wall, and it also increases the work intensity of the operators. Moreover, the stability of the brick wall is not strong enough. The wall is prone to collapse during pouring and filling, which affects the construction progress of the goaf filling.

[0006] Furthermore, the auxiliary support assembly includes a first support tube, the top end of which is movably connected to the outer wall of the retaining wall, a second support tube is slidably connected in the inner cavity of the first support tube, a screw hole is opened on the side wall of the first support tube, a bolt is threaded in the screw hole, and a plurality of sockets are evenly opened on the side wall of the second support tube along the length direction.

[0007] Furthermore, a pad is hinged at the bottom end of the second support tube.

[0008] Furthermore, a plurality of anti-slip studs are evenly arranged on the bottom wall of the pad.

[0009] Furthermore, a groove is provided on the outer side wall of the retaining wall, and the top end of the first support tube is rotatably connected to the inner side wall of the groove through a rotating rod, so that the first support tube and the second support tube can be matched and placed in the groove after being contracted.

[0010] Furthermore, a plurality of the blind holes are evenly opened from top to bottom on the side walls at both ends of the retaining wall.

[0011] Furthermore, a lifting lug is installed on the outer side wall of the retaining wall.

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 3 As shown, a retaining wall for filling a mine goaf includes a retaining wall 1, blind holes 2 are horizontally opened on the side walls at both ends of the retaining wall 1, an insertion rod 3 is slidably connected in the blind hole 2, a sliding groove 4 is opened on the outer wall of the retaining wall 1, the sliding groove 4 is connected to the blind hole 2, a lever 5 is slidably connected in the sliding groove 4, the inner end of the lever 5 is fixedly connected to the side wall of the insertion rod 3, and an auxiliary support assembly is arranged on the outer wall of the retaining wall 1; a plurality of the blind holes 2 are evenly opened on the side walls at both ends of the retaining wall 1 from top to bottom.

[0019] Specifically, by setting up the retaining wall 1 in the goaf, the time required for setting up the retaining wall during the pouring and filling construction is shortened, and the retaining wall 1 has strong stability and is not prone to collapse.

[0020] In actual use, first, holes are opened on both side walls at the entrance of the underground goaf, and then the retaining wall 1 is erected at the entrance of the goaf.
