Description

Technical Field

[0001] The invention relates to the technical field of paste filling, and in particular to a mine mobile hydraulic filling retaining wall and a use method thereof. Background Art

[0002] In the mining industry, mines need to be filled after mining. As a mining method with high safety, environmental protection and low loss and depletion rate, the filling method has been increasingly used. After mining by the filling method, the remaining goaf needs to be filled in time to avoid the fall of surrounding rock, so as to ensure that the ore can be mined safely and efficiently under the protection of the filling body.

[0003] The backfill mining method has high requirements for the stability, safety and efficiency of the backfill retaining wall. The purpose of the backfill retaining wall is to prevent the paste filling slurry from leaking out during backfilling. At the same time, it also needs to withstand the lateral static pressure and dynamic pressure applied before the paste filling slurry solidifies. At present, the commonly used backfill retaining walls at home and abroad mainly include concrete retaining walls, brick retaining walls, log retaining walls, steel structure retaining walls and sandbag retaining walls. For example, the utility model patent with authorization announcement number CN208416605U discloses a high-concentration tailings cemented and filled reinforced concrete retaining wall. The main body of the retaining wall is a reinforced concrete structure. The retaining wall main body is connected to the inner wall of the mining tunnel by groove casting on all sides. The two ends of the through steel bars in the retaining wall main body are embedded in the inner wall of the mining tunnel, so that the retaining wall main body and the inner wall of the mining tunnel are firmly connected. However, its main body is a traditional concrete retaining wall, which has the problems of large masonry work volume, high cost, and long maintenance time. Brick retaining walls also have the problems of complicated construction procedures, high labor intensity of workers, one-time investment of materials, and inability to be recycled and reused. Secondly, they have poor bending resistance and are prone to local displacement, deformation, cracking, and even collapse. The construction quality of wooden retaining walls, steel structure retaining walls, and sandbag retaining walls is difficult to guarantee, and the professional requirements for construction personnel are high. The strength and anti-seepage performance of the retaining walls are poor.

[0004] With the expansion of production scale, the improvement of production efficiency and the strictness of production safety, the construction efficiency and safety requirements of filling retaining walls are becoming higher and higher. At the same time, the requirements for reducing the cost of filling retaining walls and the repeated recycling of filling retaining walls are also becoming higher and higher. The existing filling retaining wall technology has low disassembly and assembly efficiency, low material recycling rate and low safety and stability. Therefore, mechanized and efficient filling retaining wall production has become an important part of the on-site application of paste filling mining method.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 7 As shown, the present invention provides a mobile hydraulic filling retaining wall for a mine, comprising a frame fixed in a tunnel and a shovel loader 1 located in the tunnel, a flexible filling wall 6 is arranged on the frame, the flexible filling wall 6 is filled with a filling body 7, and the filling body 7 overflows into the tunnel on one side of the flexible filling wall 6 and fills the tunnel, the other side of the flexible filling wall 6 is detachably connected to a movable supporting structure 5, a side of the movable supporting structure 5 facing away from the flexible filling wall 6 is connected to a filling hydraulic folding bracket 4, a side of the filling hydraulic folding bracket 4 facing away from the movable supporting structure 5 is detachably connected to an upper fixed rod 2 and a lower fixed rod 3, and the upper fixed rod 2 and the lower fixed rod 3 are both connected to the shovel loader 1.

[0040] Among them, the filling hydraulic folding support 4 can be bent and fixed in the tunnel through hydraulic support, and the movable support structure 5 is pressed by the shovel loader 1. The movable support structure 5 can adjust the support angle and is used to support the flexible filling wall 6. The flexible filling wall 6 is used to close the tunnel to limit the leakage of the filling body 7.

[0041] When the technical solution of the present invention is implemented, the shovel loader 1 can transport the flexible filling wall 6, the movable support structure 5 and the filling hydraulic folding support 4 to the construction site (the tunnel in the mining area) in the mining area access road, and then the shovel loader 1 erects the filling hydraulic folding support 4 through the upper fixing rod 2 and the lower fixing rod 3, so that the filling hydraulic folding support 4 is pressed against the top and bottom of the tunnel, fixes the frame, and installs the flexible filling wall 6 on the frame, and then connects and fixes the movable support structure 5 with the flexible filling wall 6, so that the flexible filling wall 6 can be supported by the filling hydraulic folding support 4 and the movable support structure 5, and finally fills the filling body 7 into the flexible filling wall 6, so that the flexible filling wall 6 expands to fit tightly with the inner wall of the tunnel, avoiding leakage of the filling body 7, and realizing the closure and isolation of the space on one side of the flexible filling wall 6 away from the movable support structure 5, so as to achieve effective filling, and secondly, the flexible filling wall 6 can expand after filling, so that the flexible filling wall 6 has a buffering effect and has higher stability during the construction process.

[0042] The filling hydraulic folding bracket 4 and the movable supporting structure 5 both support the flexible filling wall 6 through hydraulic pressure, thereby ensuring the stability of the flexible filling wall 6 during the construction process.

[0043] While waiting for the filling body 7 to solidify, the upper fixing rod 2 and the lower fixing rod 3 can be removed from the filling hydraulic folding support 4, and the scraper 1 can be driven away from the site to perform other construction, so that the scraper 1 has a higher utilization rate.

[0044] After the filling body 7 solidifies, the filling hydraulic folding bracket 4 and the movable supporting structure 5 can be removed, thereby improving the recycling rate of the materials, and can be installed and moved by the scraper 1, thereby making the construction more efficient.

[0045] The filling hydraulic folding bracket 4 includes a support plate 401, one side of the support plate 401 is provided with an upper fixed slot 402 and a lower fixed slot 403, and the upper fixed slot 402 is used to fix the end of the upper fixed rod 2 by a pin, and the lower fixed slot 403 is used to fix the end of the lower fixed rod 3 by a pin, and the top of the support plate 401 is rotatably connected to a folding plate 404, and one side of the folding plate 404 is rotatably connected to a plurality of hydraulic telescopic rods 405 rotatably connected to the support plate 401.

[0046] The upper fixing rod 2 and the lower fixing rod 3 are respectively fixed in the upper fixing slot 402 and the lower fixing slot 403 by means of latches, so that the scraper 1 can move the support plate 401 through the upper fixing rod 2 and the lower fixing rod 3, and stand up the support plate 401, and then drive the folding plate 404 to rotate to abut against the top of the tunnel through the hydraulic telescopic rod 405, thereby fixing the entire filling hydraulic folding support 4 in the tunnel.

[0047] A push screw 406 is rotatably connected to the support plate 401, and a slide seat 407 slidably connected to the support plate 401 is threadedly connected to the push screw 406. A support rod 408 is rotatably connected to the slide seat 407, and the support rod 408 and the slide seat 407 are detachably connected. The end of the support rod 408 is rotatably connected to a slide plate 409 slidably connected to the folding plate 404, and a plurality of spikes 410 are provided on the side of the slide plate 409 facing away from the support plate 401.

[0048] Taking into account that the filling hydraulic folding support 4 will be disconnected from the upper fixing rod 2 and the lower fixing rod 3 for a period of time, the slide 407 is driven to slide upward along the support plate 401 by rotating the advancement screw 406, thereby pushing the support rod 408 to drive the slide plate 409 to move on the folding plate 404 until the spike 410 extends out of the folding plate 404 and abuts against the top of the alley. By abutting the spike 410 against the top of the alley, the resistance between the folding plate 404 and the alley is increased, thereby improving the stability of the filling hydraulic folding support 4 during use.

[0049] When the hydraulic foldable support 4 is folded, the support rod 408 and the slide seat 407 can be directly disassembled to improve the convenience of use and avoid the support rod 408 interfering with the rotation of the folding plate 404.

[0050] The support plate 401 is connected with a plurality of support screws 411 for contacting the ground via inclined threads. Each support screw 411 is provided with a rotating handle 412 , and the plurality of support screws 411 are inclined downward in a direction away from the movable support structure 5 .

[0051] Taking into account that the filling hydraulic folding bracket 4 will be disconnected from the upper fixed rod 2 and the lower fixed rod 3 for a period of time, the supporting screw 411 is driven to rotate by turning the rotating handle 412, so that the bottom of the supporting screw 411 gradually tilts downward until it is against the ground, thereby supporting the support plate 401, further improving the stability of the filling hydraulic folding bracket 4 during use.

[0052] The movable support structure 5 includes multiple hydraulic mechanisms 501 connected to the support plate 401, and the multiple hydraulic mechanisms 501 are commonly connected to a hydraulic plate 502.

The hydraulic telescopic skeletons 503 can be fixed on the flexible filling wall 6 by wire, etc.

[0054] The flexible filling wall 6 includes a water bag 601, which includes an upper water bag 604, a middle water bag 605 and a lower water bag 606, which are arranged on one side of the frame from top to bottom, and the upper water bag 604 is open, and the middle water bag 605 and the lower water bag 606 are both closed.

The middle water bag 605 and the lower water bag 606 are connected to a filling pipe 608 through a filling pipe joint, and multiple filling pipes 608 and multiple return air pipes 609 are fixed in the tunnel through fixed chains.

[0055] The flexible filling wall 6 is filled with the filling body 7 through the upper water bag 604, the middle water bag 605 and the lower water bag 606. The filling body 7 is the slurry used for existing filling. The filling body 7 is poured into the upper water bag 604, the middle water bag 605 and the lower water bag 606 through multiple filling pipes 608 until they overflow from multiple return air pipes 609.

[0056] The transparent plastic sheet 602 and the steel mesh 603 are used to seal the gap between the inner wall of the tunnel and the upper water bag 604, the middle water bag 605, and the lower water bag 606, so that after the upper water bag 604, the middle water bag 605, and the lower water bag 606 are filled with the filling body 7 and expanded, the transparent plastic sheet 602 can fit tightly on the inner wall of the tunnel and fix the positions of the transparent plastic sheet 602, the upper water bag 604, the middle water bag 605, and the lower water bag 606.
