[0050] The present invention provides a magnetic levitation structure filling retaining wall.

[0051] like Figures 1 to 6 A magnetic levitation structure filling retaining wall is shown, comprising:

[0052] Two suspension electromagnet columns 1, both of which are vertically and parallelly spaced apart; the two suspension electromagnet columns 1 are used to form a strong magnetic field in the construction direction;

[0053] Two permanent magnetic columns 2, the two permanent magnetic columns 2 are located on the side of the two suspension electromagnet columns 1 facing the construction direction, the two permanent magnetic columns 2 are parallel to the two suspension electromagnet columns 1, and the two permanent magnetic columns 2 are arranged at intervals; one of the suspension electromagnet columns 1 is used to support one of the permanent magnetic columns 2 through a strong magnetic field, and the other suspension electromagnet column 1 supports the other permanent magnetic column 2 through a strong magnetic field;

[0054] The connecting structure is located between the two permanent magnetic columns 2 and connects the two permanent magnetic columns 2 respectively.

[0055] The connection structure connects the two permanent magnetic columns 2 to form an overall structure, and then the strong magnetic field formed by the two suspended electromagnet columns 1 provides adjustably supported support for the overall structure, so that the supporting force can be adjusted in real time according to the actual situation of filling the retaining wall, effectively ensuring the normal progress of the operation.

[0056] Specifically, the suspended electromagnet column 1 includes a coil and an iron core. The coil is perpendicular to the direction of the mining area access and is wound around the iron core. A strong magnetic field can be generated by connecting the coil to current, and the strength of the strong magnetic field is adjusted according to the size of the input current.

[0057] Specifically, the N pole of the magnetic field direction of the permanent magnetic column 2 is close to the construction direction, and the S pole of the magnetic field direction of the permanent magnetic column 2 is far away from the construction direction; the magnetic field direction of the suspension electromagnet column 1 supporting the permanent magnetic column 2 is opposite to the magnetic field direction of the supported permanent magnetic column 2.

[0058] The connection structure includes at least one horizontal brace 3 and two vertical braces 4. Each horizontal brace 3 is positioned between the two permanent magnet columns 2. Each horizontal brace 3 extends from one permanent magnet column 2 toward the other, and is vertically spaced and arranged in parallel. One end of each horizontal brace 3 is detachably connected to one permanent magnet column 2, and the other end is detachably connected to the other permanent magnet column 2. Both vertical braces 4 are detachably positioned on the side of each horizontal brace 3 facing the two suspension electromagnet columns 1. The coordination of multiple horizontal braces 3 and two vertical braces 4 ensures structural strength when the connection structure is constructed on the side facing away from the two suspension electromagnet columns 1. Furthermore, the use of the connection structure eliminates the need for anchor bolting, improving construction efficiency.

[0059] The cross brace 3 comprises a center beam 31, two end beams 32, and two connectors 5. The center beam 31 has a through slot 33 on the side facing the two suspension electromagnet columns 1. The through slots 33 extend through the ends of the center beam 31 near the two permanent magnet columns 2. One end of one end beam 32 is inserted into one end of the through slot 33 and is removably connected to the center beam 31 via one of the connectors 5. One end of the other end beam 32 is inserted into the other end of the through slot 33 and is removably connected to the center beam 31 via another connector 5. The ends of the two end beams 32 facing away from the center beam 31 are removably connected to the adjacent permanent magnet columns 2. This integrated cross beam structure ensures structural strength while facilitating installation and removal, allowing for easy reuse and high reusability.

[0060] Specifically, the middle beam 31 is a channel steel.

[0061] The connecting member 5 includes:

[0062] A fixing plate 51, one side of which is provided with two sets of insertion structures. The fixing plate 51 is provided at the end of the middle beam 31 and faces one side of the two suspension electromagnet columns 1;

[0063] The connecting plate 52 has two socket groups along the thickness of the plate. The fixing plate 51 is arranged on the side of the middle beam 31 away from the fixing plate 51. One of the insertion structures is inserted into one of the socket groups, and the other insertion structure is inserted into the other socket group.

[0064] Two fasteners are provided on a side of the connecting plate 52 facing away from the fixing plate 51 , and the two fasteners are respectively detachably connected to adjacent insertion structures.

[0065] Specifically, one set of insertion structures is located at one end of the fixing plate 51 close to one of the permanent magnetic pillars 2, and the other set of insertion structures is located at one end of the fixing plate 51 close to the other permanent magnetic pillar 2, which further improves the strength of the overall structure of the cross brace 3.

[0066] The insertion structure includes two inserting plates 53, which extend along the fixed plate 51 toward the connecting plate 52. The two inserting plates 53 are vertically parallel and spaced apart. A first fixing through hole 54 is formed along the thickness of the plate at one end of the inserting plate 53 away from the fixed plate 51.

[0067] The socket assembly includes two connecting through holes 55 ; one plug-in board 53 is inserted into one of the connecting through holes 55 , and the other plug-in board 53 is inserted into the other connecting through hole 55 ;

[0068] The fastener includes a first bolt 56 and a first nut 57 . The first bolt 56 passes through the two first fixing through holes 54 in sequence and is threadedly connected to the first nut 57 .

[0069] The two insert plates 53 are limited by two fasteners (i.e., two first bolts 56 and two first nuts 57) so that the fixing plate 51 and the connecting plate 52 clamp the end beam 32 and insert it into the connection of the middle beam 31, ensuring the structural strength of the connection between the end beam 32 and the middle beam 31.

[0070] Specifically, the first fixing through hole 54 of the middle plug plate 53 of the insertion structure is coaxially arranged.

[0071] A second fixing through hole 34 is vertically opened at one end of the end beam 32 away from the middle beam 31; the connection structure also includes two fixing parts, one of which is arranged on the side of one of the permanent magnetic columns 2 facing the middle beam 31, and the other fixing part is arranged on the side of the other permanent magnetic column 2 facing the middle beam 31; the end of the end beam 32 away from the middle beam 31 is detachably connected to the adjacent fixing part and the second fixing through hole 34 through a second bolt and a second nut, respectively.

[0072] Specifically, a second fixing through hole 34 is also provided at one end of the end beam 32 close to the middle beam 31. This arrangement facilitates the staff to use the two ends of the end beam 32 alternately, ensuring that the two ends of the end beam 32 can be used alternately and reducing the difficulty of operation.

[0073] The fixings include two connecting plates 21, which are positioned on the side of the permanent magnetic column 2 facing the intermediate beam 31. The two connecting plates 21 have third fixing holes 22 defined along the plate thickness, with the two third fixing holes 22 coaxially arranged. One end of the end beam 32, which has a second fixing hole 34, is inserted between the two connecting plates 21. A second bolt is threadedly connected to the second nut by sequentially passing through one of the third fixing holes 22, the second fixing hole 34, and the other third fixing hole 22. The end beam 32 is first inserted between the two connecting plates 21, and then secured between the two connecting plates 21 using the second bolt and the second nut, thereby achieving a removable fixed connection between the end beam 32 and the permanent magnetic column 2.

[0074] The vertical support 4 comprises a plurality of vertical rods 41, each of which is connected in sequence along the vertical axis. One end of each vertical rod 41 is a movable end 42, and the other end of each vertical rod 41 defines a slot extending along its length. The movable end 42 of one of two adjacent vertical rods 41 can be removably inserted into the slot of the other vertical rod 41. Threaded through-holes 43 are defined in the sidewalls of each vertical rod 41, connecting to the slot. The number of vertical rods 41 can be adjusted according to the height of the roadway, so that the vertical support 4 formed by each vertical rod 41 can better support the retaining wall.

[0075] The threaded through hole 43 is used to screw in a fixing bolt to fix the relative position of two adjacent uprights 41, thereby further improving the structural strength.

[0076] Specifically, the length of the movable end 42 is 50 cm, and the movable end 42 is a solid round steel with a diameter of 30 mm; the length of the vertical pole 41 is 100 cm, and the vertical pole 41 is a solid round steel with a diameter of 50 mm; the depth of the slot along the length direction of the vertical pole 41 is 50 cm, and the part of the vertical pole 41 where the slot is opened is a hollow round steel with a thickness of 10 mm; the distance between the threaded through hole 43 and the notch of the slot is 10 cm, and the threaded through hole 43 is an internal threaded hole with a diameter of 20 mm.

[0077] One of the vertical supports 4 is removably secured to the side of each intermediate beam 31 facing the two levitation electromagnet columns 1 via one of the connectors 5. The other vertical support 4 is removably secured to the side of each intermediate beam 31 facing the two levitation electromagnet columns 1 via another connector 5. The two vertical supports 4 are parallel to the permanent magnet columns 2 and spaced apart. The intermediate beams 31, end beams 32, and vertical supports 4 are each secured to the intermediate beams 31, end beams 32, and vertical supports 4, ensuring the overall structural strength of the connection structure.

[0078] Specifically, the vertical support 4 is fixed between the middle beam 31 and the fixing plate 51 .

[0079] A method for constructing a retaining wall filled with a magnetic levitation structure, wherein the method employs any one of the above-mentioned retaining walls filled with a magnetic levitation structure, and the method comprises:

[0080] Determine the first installation position of the two suspension electromagnet columns 1 according to the position of the filling retaining wall;

[0081] Fix the two suspension electromagnet columns 1 at the first installation position through an external fixing mechanism;

[0082] Specifically, a suitable location for constructing a filling retaining wall is selected at the stope access; the upper and lower ends of the suspended electromagnet column 1 are inserted into the stope access through the top and bottom plates and fixed.

[0083] Determine the second installation position of the two permanent magnetic columns 2 according to the preset distance and construction direction, and set the two permanent magnetic columns 2 at the second preset position;

[0084] Specifically, the preset distance is one meter.

[0085] The two suspension electromagnet columns 1 are energized so that the two suspension electromagnets support the two permanent magnetic columns 2 through a strong magnetic field according to preset parameters;

[0086] Specifically, the preset parameters are calculated and determined based on the actual on-site conditions.

[0087] Connect the connection structure to the two permanent magnetic pillars 2 respectively;

[0088] Specifically, first insert the end beam 32 of each cross brace 3 between the two adjacent connecting plates 21; then fix the end beam 32 and the permanent magnetic column 2 relatively to each other by the second bolt and the second nut, so that each end beam 32 and the adjacent permanent magnetic column 2 can be detachably fixed; then insert the end beams 32 of each cross brace 3 into the end of the middle beam 31 of each cross brace 3, and adjust the position of the middle beam 31 so that the length of the middle beam 31 plus the end beam 32 is just equal to the width of the mining area access road; determine the number of vertical poles 41 according to the actual height in the tunnel, and connect the vertical poles 41 after the determined number in turn, and assemble the vertical poles 41 into vertical poles 4 by screwing in fixing bolts equal to the number of vertical poles 41; place one of the vertical poles 4 close to the left end of each middle beam 31, and place the other vertical pole 4 close to the right end of each middle beam 31; finally, install the fixing parts in turn, and tighten the first bolt 56 and the first nut 57 to fix the relative positions of each cross brace 3 and the two vertical poles 4.

[0089] Specifically, the distance between the two vertical supports 4 is 50CM.

[0090] On the connecting structure away from the two suspended electromagnet columns 1, wire mesh, geotextile and dewatering pipes are laid in sequence, and then the filling operation is started.

[0091] Specifically, when performing the filling operation, the actual operation conditions are observed and the current intensity of the two suspension electromagnet columns 1 is adjusted according to the actual conditions to ensure that the two suspension electromagnet columns 1 effectively support the two permanent magnet columns 2 .
