DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to solve the technical problems that brick retaining walls consume a long time to build and have poor lateral tilt resistance, the utility model provides a mine filling retaining wall.

[0018] See also Figure 1 , Figure 1 This is a schematic structural diagram of a mine filling retaining wall after masonry in an embodiment of the utility model. The mine filling retaining wall includes a retaining wall body 1 and a spliced ​​baffle assembly 2.

[0019] See also Figure 1-Figure 5 The retaining wall body 1 includes a bottom plate 11 and a main retaining plate 12, wherein the bottom plate 11 is vertically fixed to the main retaining plate 12, and the bottom plate 11 is used to be fixed to the ground of the goaf through a plurality of lower fixing nails 111, and a slot 121 is provided on the upper end surface of the main retaining plate 12;

[0020] The splicing baffle assembly 2 includes a plurality of splicing assemblies, each of which includes a splicing baffle 21 and a height adjustment member 22. The splicing baffle 21 of each of the splicing assemblies is slidably inserted into the slot 121 and is sequentially spliced ​​along the length direction of the main baffle 12. One end of each of the height adjustment members 22 is connected to the main baffle 12, and the other end of each of the height adjustment members 22 is respectively connected to the corresponding splicing baffle 21 and is used to adjust the height of the corresponding splicing baffle 21.

[0021] When in use, first place the bottom plate 11 at a preset position on the ground of the goaf, then use hammering or other methods to penetrate the bottom plate 11 and insert the lower fixing nails 111 into the ground, so that the bottom plate 11 is firmly fixed to the ground of the goaf, and then adjust the height of each spliced ​​baffle 21 through each height adjustment member 22, so that the upper end of each spliced ​​baffle 21 is in contact with the inner top surface of the ground of the goaf. At this time, the middle part of the passage of the goaf has been blocked by the mine filling retaining wall, and there is still a gap between the two sides of the mine filling retaining wall and the side walls of the goaf. At this time, brick wall retaining walls 3 are respectively built in the gaps on both sides of the retaining wall, so as to achieve full blocking of the passage of the goaf, and then the slurry filling can be carried out after the brick wall retaining wall 3 is completely solidified.

[0022] Preferably, the width of the main baffle plate 12 should be greater than the width of the bottom plate 11, so that both ends of the main baffle plate 12 protrude from the bottom plate 11. When the brick wall retaining wall 3 is built, the protruding part of the main baffle plate 12 is covered by the brick wall retaining wall 3, thereby improving the fixing strength between the brick wall retaining wall 3 and the main baffle plate 12.

[0023] The mine filling retaining wall provided by the utility model fixes the bottom plate 11 to the ground of the goaf area by a plurality of lower fixing nails 111, so as to improve the lateral stability of the filling retaining wall (Note: in the utility model, lateral refers to the direction perpendicular to the retaining wall). By arranging a plurality of spliced ​​baffles 21 spliced ​​in sequence above the main baffle 12, the upper end of each spliced ​​baffle 21 can be moved up to fit with the top surface in the goaf, thereby improving the barrier effect of the filling retaining wall in the height direction. During actual installation, it is only necessary to build brick wall retaining walls 3 on both sides of the filling retaining wall, which can reduce the building area of ​​the brick wall retaining wall 3 and shorten the installation time of the filling retaining wall.

[0024] In one embodiment, see Figure 3-Figure 5 A mounting plate 13 is fixed on the side wall of the main baffle 12, and a plurality of screw holes extending in the vertical direction are evenly opened on the mounting plate 13 along the length direction; each of the height adjustment members 22 includes an adjusting screw 221, and the adjusting screw 221 is threadedly inserted into the corresponding screw hole of the mounting plate 13, and the upper end of the adjusting screw 221 is fixedly connected to the corresponding splicing baffle 21.

[0025] In one embodiment, see Figure 3-Figure 5 Each of the height adjustment members 22 further includes a fixing plate 222 and a bearing 223. The fixing plate 222 is fixed on the corresponding splicing baffle 21. The inner ring of the bearing 223 is fixedly sleeved on the upper end of the corresponding adjusting screw 221. The outer ring of the bearing 223 is fixed on the corresponding fixing plate 222.

[0026] During use, when the height of the corresponding splicing baffle 21 needs to be adjusted through the height adjustment member 22, the adjustment screw 221 is rotated, and the adjustment screw 221 rises or falls, thereby driving the corresponding splicing baffle 21 to rise or fall through the bearing 223 and the fixing plate 222.

[0027] In one embodiment, see Figure 3-Figure 5 There are two mounting plates 13, and each mounting plate 13 is evenly provided with a plurality of screw holes extending in the vertical direction along the length direction; each adjusting screw 221 is threadedly inserted into the corresponding screw holes of the two mounting plates 13 in sequence. By setting two mounting plates 13, the stability of each adjusting screw 221 can be improved, thereby improving the stability of each splicing baffle 21.

[0028] In one embodiment, see Figure 3-Figure 5 The mounting plate 13 is also provided with a plurality of upper fixing holes, and the retaining wall body 1 also includes a plurality of upper fixing nails 14, which are fixed to the top surface of the goaf after passing through the corresponding upper fixing holes. By setting the upper fixing nails 14, the lateral stability of the filling retaining wall can be further improved.

[0029] In one embodiment, see Figure 3-Figure 5 A rubber pad 211 is fixed to the upper end of each of the spliced ​​baffles 21. Since the rubber pad 211 is easy to deform, it can better fit closely with the inner top surface of the goaf.

[0030] In one embodiment, see Figure 3-Figure 5 A plurality of lower fixing holes are formed on the bottom plate 11, and each of the lower fixing nails 111 passes through the corresponding lower fixing hole and is fixed to the ground of the goaf.

[0031] In one embodiment, see Figure 3-Figure 5The retaining wall body 1 further includes an oblique brace 15, which is arranged obliquely, one end of which is fixedly connected to the bottom plate 11, and the other end of which is fixedly connected to the main baffle 12. By providing the oblique brace 15, the connection strength between the bottom plate 11 and the main baffle 12 can be improved. Specifically, one end of the oblique brace 15 is fixedly connected to the bottom plate 11 via a first protrusion 151. The other end of the oblique brace 15 is fixedly connected to the main baffle 12 via a second protrusion 152.

[0032] In order to better understand the present invention, the following Figures 1 to 5 The technical scheme of the utility model is described in detail: when in use, first place the bottom plate 11 at a preset position on the ground of the goaf, then insert each lower fixing nail 111 into the ground after passing through the lower fixing hole of the bottom plate 11 by hammering or the like, so that the bottom plate 11 is firmly fixed to the ground of the goaf, then rotate each adjusting screw 221 respectively to adjust the height of each spliced ​​baffle 21, so that the upper end of each spliced ​​baffle 21 abuts against the inner top surface of the ground of the goaf. At this time, the middle part of the channel of the goaf has been blocked by the mine filling retaining wall, and there is still a gap between the two sides of the mine filling retaining wall and the side wall of the goaf. At this time, brick wall retaining walls 3 are respectively built in the gaps on both sides of the retaining wall, so as to achieve full blocking of the channel of the goaf, and then the slurry filling can be carried out after the brick wall retaining wall 3 is completely solidified.

[0033] The mine filling retaining wall provided by the utility model fixes the bottom plate 11 to the ground of the goaf area by a plurality of lower fixing nails 111, so as to improve the lateral stability of the filling retaining wall. By arranging a plurality of spliced ​​baffles 21 which are spliced ​​in sequence above the main baffle plate 12, the upper end of each spliced ​​baffle plate 21 can be moved up to fit with the top surface in the goaf, so as to improve the barrier effect of the filling retaining wall in the height direction. During the actual installation, it is only necessary to build the brick wall retaining wall 3 on both sides of the filling retaining wall, which can reduce the building area of ​​the brick wall retaining wall 3 and shorten the installation time of the filling retaining wall.

[0034] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
