Description

Technical Field

[0001] This invention relates to the field of mine slope reinforcement technology, specifically to a frame beam structure for mine slope reinforcement and its reinforcement method. Background Technology

[0002] To prevent safety hazards caused by falling rocks from mine slopes, slope protection measures are necessary. Mine slope protection refers to the reinforcement structures installed on the slopes to ensure the safety of the mine slopes and their surrounding environment.

[0003] Existing mine slope reinforcement structures generally adopt protective net anchoring structures, such as the announcement number CN112900457B, which is named a mine slope reinforcement structure and relates to the field of mine slope protection. It includes several protective nets covering the slope, and fixing components are set at the connection of the top corners of adjacent protective nets. The fixing components include fixing plates and several fixing columns. The fixing plates have several fixing holes that correspond one-to-one with the fixing columns. The fixing columns are inserted into the fixing holes. The bottom end of the fixing column is pointed. The top of the fixing column has a first grouting hole. The side of the fixing column has several reinforcement holes that communicate with the first grouting hole.

[0004] However, existing slope reinforcement methods, where the stress point is on the slope surface, can damage the surrounding soil structure after the expandable anchors open, causing the surrounding soil to soften and leading to the failure of the anchoring system. The construction process while waiting for grouting is also highly dangerous. Therefore, we provide a frame beam structure for mine slope reinforcement and its reinforcement method. Summary of the Invention

[0005] The purpose of this invention is to provide a frame beam structure and its reinforcement method for mine slope reinforcement, in order to solve the problems mentioned in the background art, where the stress point is on the slope surface, and the expandable anchor will damage the surrounding soil structure after it opens, making the surrounding soil soft, thus causing the anchoring system to fail, and the construction is highly dangerous during the waiting grouting process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a frame beam structure for mine slope reinforcement, comprising a mine slope, wherein the bottom surface of the mine slope is provided with a slope bottom and the top surface of the mine slope is provided with a slope top;

[0007] Also includes:

[0008] The first grouting trench is located inside the bottom of the slope. The inner walls of the first grouting trench are equipped with baffles on all four sides, and the interior of the first grouting trench is equipped with steel reinforcement supports.

[0009] A frame positioning support is installed above the top of the slope, and a second grouting groove is provided inside the frame positioning support;

[0010] A positioning top frame is provided at the front end of the frame positioning support, and the positioning top frame is welded to the frame positioning support.

[0011] A frame beam is installed on the outer wall of the positioning top frame, and multiple frame beams are provided. One end of the frame beam passes through and extends into the interior of the first grouting groove and is welded to the steel reinforcement support. A protective net group is installed between adjacent frame beams.

[0012] The first concrete layer fills the interior of the first grouting trench;

[0013] The second concrete layer fills the interior of the second grouting trench;

[0014] During reinforcement, firstly, a frame positioning support is erected at the top of the mine slope. During erection, grounding stakes are driven into the base layer of the slope top along the inside of the frame positioning support. After completion, tools are used to insert the stakes into the cross grooves at the ends of the inner rods, rotate them, and remove the inner rods. Next, a first grouting trench is excavated at the bottom of the mine slope, and retaining plates are installed along the inner edge of the trench. After laying a layer of sand and gravel on the bottom surface, a steel reinforcement support is placed. Then, a positioning top frame is installed and positioned at the front end of the frame positioning support, allowing the frame beams and retaining mesh to hang vertically on the mine slope. Finally, the positioning rods at the rear end of the positioning top frame are inserted into the positioning supports on the frame positioning support. In the insertion hole, personnel weld the positioning top frame to the frame positioning support to complete the initial fixation of the two. Personnel then apply pressure to the frame beam section from top to bottom using mechanical equipment, causing the frame beam section to bend and adhere to the slope under the action of the hinge joint. The bottom end of the frame beam is extended into the first grouting groove, and personnel weld and fix the bottom end of the frame beam to the steel reinforcement support. Concrete grout is poured into the first and second grouting grooves. The concrete in the first grouting groove strengthens the connection strength between the frame positioning support and the positioning top frame, and the concrete in the second grouting groove strengthens the connection strength between the bottom end of the frame beam and the steel reinforcement support.

[0015] Preferably, the second grouting trench is provided with grounding stakes inside, and multiple grounding stakes are provided. The lower ends of the multiple grounding stakes all penetrate through and extend to the outside of the frame positioning support. The frame positioning support is fixedly connected to the top of the slope through the grounding stakes.

[0016] Preferably, the grounding stake includes a straight rod section, a drilling tip, and a limiting head. The limiting head is located at the upper end of the straight rod section, the drilling tip is located at the lower end of the straight rod section, and the outer wall of the lower end of the straight rod section is provided with a threaded wall.

[0017] Preferably, the straight rod section has an inner rod inside, and the upper end of the inner rod has an inner rod end. The inner rod end is threadedly connected to the limiting head through a threaded mechanism. The upper end of the inner rod end has a cross groove. The outer wall of the straight rod section has grouting holes all around, and there are multiple grouting holes.

[0018] Preferably, the front end of the frame positioning support is provided with positioning holes, and there are multiple positioning holes, which are equidistantly distributed. The rear end of the positioning top frame is provided with positioning rods, and there are multiple positioning rods, which are equidistantly distributed. The positioning top frame is connected to the positioning holes on the frame positioning support through the positioning rods.

[0019] Preferably, the frame beam includes frame segments and flexible connection nodes, wherein multiple frame segments are provided, and the flexible connection nodes are provided between multiple frame segments.

[0020] Preferably, the flexible connection node includes a hinge joint and a rubber sleeve. The hinge joint is installed at the end of the frame segment, and the hinge joints between adjacent frame segments are rotatably connected by a damping shaft. The rubber sleeve is disposed outside the hinge joint and is bonded to the frame segment.

[0021] Preferably, the bottom surface of the frame segment is provided with an inner groove, the interior of the inner groove is provided with a water-inducing adhesive layer, and both sides of the inner groove are provided with water seepage grooves, and there are multiple water seepage grooves.

[0022] Preferably, the protective mesh assembly includes a reinforcing mesh and a wire mesh, with the wire mesh positioned at the rear end of the reinforcing mesh.

[0023] Preferably, a method for reinforcing a frame beam structure used for mine slope reinforcement includes the following steps:

[0024] Step 1: Clean the slope, removing obvious debris and large stones;

[0025] Step 2: Apply fertilizer and lime powder to initially solidify the slope soil, and sow vegetation seeds. The vegetation seeds are one or more of the following: perennial ryegrass, bermudagrass, tall fescue, ryegrass, and Kentucky bluegrass.

[0026] Step 3: Erect a frame positioning support at the top of the mine slope. During the erection, drive the grounding pile into the base layer at the top of the slope along the inside of the frame positioning support. After completion, use a tool to insert it into the cross groove at the end of the inner rod of the grounding pile. After rotating, take out the inner rod. Dig the first grouting trench at the bottom of the mine slope and install a retaining plate on the edge of the inner wall of the first grouting trench. After laying a layer of sand and gravel on the bottom surface, put in the steel reinforcement support.

[0027] Step 4: Set up the positioning top frame and place it at the front end of the frame positioning support so that the frame beam and the retaining net assembly hang down on the mine slope. After completion, insert the positioning rod at the rear end of the positioning top frame into the positioning hole on the frame positioning support. Then, the positioning top frame and the frame positioning support are welded together to complete the initial fixation of the two.

[0028] Step 5: Personnel use mechanical equipment to apply pressure to the frame beam section from top to bottom, causing the frame beam section to bend and adhere to the slope under the action of the hinge joint, and extend the bottom end of the frame beam into the first grouting groove. Personnel then weld and fix the bottom end of the frame beam to the steel reinforcement support.

[0029] Step Six: Pour concrete slurry into the first grouting tank and the second grouting tank, based on the connection strength between the concrete reinforcement frame positioning support and the positioning top frame in the first grouting tank, and the connection strength between the bottom end of the concrete reinforcement frame beam and the steel reinforcement support in the second grouting tank.

[0030] Step 7: Spray clean water evenly onto the mine slope to maintain vegetation. While the water seeps in through the drainage holes on the side of the bottom of the frame section, it comes into contact with the water-activated adhesive layer. When the water comes into contact with the adhesive layer, its hydrophobic skeleton shrinks, and the hyperbranched polymer inside coagulates, thereby quickly removing the water from the surface of the matrix. Meanwhile, the more hydrophilic catechol is exposed, thus making full contact with the matrix and generating an adhesion effect to fix the frame section to the slope, thereby reinforcing the mine slope.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. During reinforcement using this invention, a frame positioning support is first erected at the top of the mine slope. During erection, grounding stakes are driven into the base layer of the slope top along the inside of the frame positioning support. After completion, tools are used to insert the stakes into the cross grooves at the ends of the inner rods. After rotation, the inner rods are removed. A first grouting trench is excavated at the bottom of the mine slope, and retaining plates are installed along the inner edge of the first grouting trench. After laying a layer of sand and gravel on the bottom surface, a steel reinforcement support is placed. Then, a positioning top frame is installed and positioned at the front end of the frame positioning support, allowing the frame beam and retaining mesh assembly to hang vertically on the mine slope. After completion, the positioning rod at the rear end of the positioning top frame is inserted into the positioning hole on the frame positioning support. Personnel weld the positioning top frame to the frame positioning support to complete the initial fixation. Personnel then use mechanical equipment to fix the frame beam section by section from top to bottom. Pressure is applied to bend and attach the frame beam to the slope under the action of the hinged joint, and the bottom end of the frame beam extends into the first grouting trench. The bottom end of the frame beam is then welded and fixed to the steel reinforcement support by personnel. Concrete grout is poured into the first and second grouting trenches. The concrete in the first grouting trench strengthens the connection between the frame positioning support and the positioning top frame, and the concrete in the second grouting trench strengthens the connection between the bottom end of the frame beam and the steel reinforcement support. The fixing points of the frame beam are mainly located at the top and bottom of the slope, which has no impact on the slope ecology itself. The operation is highly safe and solves the problem that in existing slope reinforcement, the stress point is on the slope surface, and the expandable anchor will damage the surrounding soil structure after opening, making the surrounding soil soft and causing the anchoring system to fail. The construction is also more dangerous during the waiting period for grouting.

[0033] 2. Before operation, this invention first applies fertilizer and lime powder to the slope to initially solidify the slope soil, and then sows vegetation seeds. Water is then evenly sprayed onto the mine slope to maintain the vegetation. Simultaneously, water seeps in through the drainage holes on the side of the frame section's bottom, contacting the water-activated adhesive layer. Upon contact with water, the hydrophobic framework of the adhesive layer shrinks, and the internal hyperbranched polymers aggregate, quickly removing moisture from the matrix surface. Meanwhile, the more hydrophilic catechol is exposed, allowing for full contact with the matrix and creating an adhesive effect that fixes the frame section to the slope, thus reinforcing the mine slope. Later, as the vegetation grows, wire mesh is gradually wrapped around it, further reinforcing the slope. Attached Figure Description

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Please see Figure 1-7 An embodiment of the present invention provides: a frame beam structure for mine slope reinforcement, including a mine slope 1, a slope bottom 2 provided on the bottom surface of the mine slope 1, and a slope top 3 provided on the top surface of the mine slope 1;

[0044] Also includes:

[0045] The first grouting trench 4 is located inside the slope bottom 2. The inner walls of the first grouting trench 4 are all equipped with baffle plates 5. The interior of the first grouting trench 4 is equipped with steel reinforcement supports 13.

[0046] The frame positioning support 7 is installed above the slope top 3, and the frame positioning support 7 is provided with a second grouting groove 8.

[0047] The positioning top frame 10 is set at the front end of the frame positioning support 7, and the positioning top frame 10 is welded to the frame positioning support 7.

[0048] A frame beam 11 is installed on the outer wall of the positioning top frame 10, and multiple frame beams 11 are provided. One end of the frame beam 11 passes through and extends into the interior of the first grouting groove 4 and is welded to the steel reinforcement support 13. A protective net group 12 is installed between adjacent frame beams 11.

[0049] The first concrete layer 6 fills the interior of the first grouting groove 4;

[0050] The second concrete layer 9 fills the interior of the second grouting groove 8;

[0051] During reinforcement, firstly, a frame positioning support 7 is erected at the top 3 of the mine slope 1. During erection, grounding stakes 16 are driven into the base layer of the top 3 of the slope along the inside of the frame positioning support 7. After completion, tools are used to insert the stakes 166 into the cross grooves 167 of the inner rod end 166. After rotation, the inner rod 168 is removed. A first grouting trench 4 is dug at the bottom 2 of the mine slope 1, and a retaining plate is installed on the inner edge of the first grouting trench 4. After laying a layer of sand and gravel on the bottom surface, a steel reinforcement support 13 is placed in. Then, a positioning top frame 10 is installed and placed at the front end of the frame positioning support 7, so that the frame beam 11 and the retaining mesh group 12 hang vertically on the mine slope 1. After completion, the positioning stake 14 at the rear end of the positioning top frame 10 is inserted into the frame positioning support 7. In the positioning socket 15, personnel weld the positioning top frame 10 to the frame positioning support 7 to complete the initial fixation of the two. Personnel then apply pressure to the frame beam 11 section by section from top to bottom using mechanical equipment, causing the frame beam 11 section to bend and adhere to the slope under the action of the hinge joint 114, and extend the bottom end of the frame beam 11 into the first grouting groove 4. Personnel then weld and fix the bottom end of the frame beam 11 to the steel reinforcement support 13. Concrete grout is poured into the first grouting groove 4 and the second grouting groove 8. The concrete in the first grouting groove 4 strengthens the connection strength between the frame positioning support 7 and the positioning top frame 10, and the concrete in the second grouting groove 8 strengthens the connection strength between the bottom end of the frame beam 11 and the steel reinforcement support 13.

[0052] Please see Figure 3 The second grouting trench 8 is equipped with grounding stakes 16. Multiple grounding stakes 16 are provided, and the lower ends of multiple grounding stakes 16 all penetrate and extend to the outside of the frame positioning support 7. The frame positioning support 7 is fixedly connected to the slope top 3 through the grounding stakes 16. The grounding stakes 16 can realize the grounding fixation of the frame positioning support 7 and the foundation of the slope top 3.

[0053] Please see Figure 4 The grounding stake 16 includes a straight rod section 161, a drilling tip 162, and a limiting head 165. The limiting head 165 is located at the upper end of the straight rod section 161, and the drilling tip 162 is located at the lower end of the straight rod section 161. A threaded wall 163 is provided on the outer wall of the lower end of the straight rod section 161. The drilling tip 162 and the threaded wall 163 can facilitate the grounding stake 16 to drill through the soil layer.

[0054] Please see Figure 4 and Figure 5 The straight rod section 161 has an inner rod 168 inside, and the upper end of the inner rod 168 has an inner rod end 166. The inner rod end 166 is threadedly connected to the limiting head 165 through a threaded mechanism 169. The upper end of the inner rod end 166 has a cross groove 167. The outer wall of the straight rod section 161 is provided with grouting holes 164 around its perimeter, and there are multiple grouting holes 164. The inner rod 168 fills the inner cavity of the grounding pile 16, ensuring the structural strength of the entire pile body during pile driving and preventing it from deforming under stress. After the grounding pile 16 is driven into the 3rd base layer of the slope top, a tool can be used to insert it into the cross groove 167 of the inner rod end 166 of the grounding pile 16, rotate it and remove the inner rod 168. During subsequent grouting, the concrete grout can enter the inner cavity of the grounding pile 16, extend along the grouting holes 164, and flow into the surrounding soil layer, which can reinforce the grounding pile 16 and the connected soil layer.

[0055] Please see Figure 2 and Figure 3 The front end of the frame positioning support 7 is provided with positioning holes 15. There are multiple positioning holes 15, and the multiple positioning holes 15 are evenly distributed. The rear end of the positioning top frame 10 is provided with positioning rods 14. There are multiple positioning rods 14, and the multiple positioning rods 14 are evenly distributed. The positioning top frame 10 is connected to the positioning holes 15 on the frame positioning support 7 through the positioning rods 14, which facilitates subsequent welding and reinforcement. The positioning rods 14 can play a role in reinforcement and strengthening after concrete is poured into the second grouting groove 8.

[0056] Please see Figure 6 The frame beam 11 includes frame segments 111 and flexible connection nodes 112. Multiple frame segments 111 are provided, and flexible connection nodes 112 are provided between multiple frame segments 111. Multiple frame segments 111 can be bent to a certain extent through flexible connection nodes 112, so as to fit more smoothly on the slope.

[0057] Please see Figure 6 The flexible connection node 112 includes a hinge joint 114 and a rubber sleeve 113. The hinge joint 114 is installed at the end of the frame segment 111, and the hinge joints 114 between adjacent frame segments 111 are rotatably connected by a damping shaft 115. The rubber sleeve 113 is disposed outside the hinge joint 114 and is bonded to the frame segment 111. The rubber sleeve 113 can protect the internal hinge joint 114.

[0058] Please see Figure 7The bottom surface of the frame segment 111 is provided with an inner groove 17, and the interior of the inner groove 17 is provided with a water-induced adhesive layer 18. Both sides of the inner groove 17 are provided with water-permeable grooves 19, and there are multiple water-permeable grooves 19. The water-induced adhesive layer 18 is prepared by a ternary Michael addition reaction of pentaerythritol tetraacrylate, short-chain polyethylene glycol diacrylate and dopamine hydrochloride. After the frame beam 11 structure is arranged, clean water is sprayed evenly on the mine slope 1 to maintain the vegetation. At the same time, the water seeps into the water-permeable grooves 19 on the bottom side of the frame segment 111 and comes into contact with the water-induced adhesive layer 18. When the water-induced adhesive layer 18 comes into contact with water, its hydrophobic skeleton shrinks and the hyperbranched polymer inside coagulates, thereby quickly removing the water from the surface of the matrix. The more hydrophilic catechol is exposed to the outside, thus making full contact with the matrix and generating an adhesive effect to fix part of the frame segment 111 to the slope, thereby achieving the reinforcement of the mine slope.

[0059] Please see Figure 6 The retaining net assembly 12 includes a steel mesh 121 and a wire mesh 122, with the wire mesh 122 positioned at the rear end of the steel mesh 121. The steel mesh 121 ensures the structural strength of the retaining net assembly 12, while the wire mesh 122 has a certain degree of toughness, allowing it to better fit the slope. Furthermore, during the growth of vegetation on the slope, it can be wrapped around the wire mesh 122 to further reinforce the slope.

[0060] Please see Figure 1-7 A method for reinforcing a frame beam structure used for mine slope reinforcement includes the following steps:

[0061] Step 1: Clean the slope, removing obvious debris and large stones;

[0062] Step 2: Apply fertilizer and lime powder to initially solidify the slope soil, and sow vegetation seeds. The vegetation seeds are one or more of the following: perennial ryegrass, bermudagrass, tall fescue, ryegrass, and Kentucky bluegrass.

[0063] Step 3: Erect a frame positioning support 7 at the top 3 of the mine slope 1. During erection, drive the grounding pile 16 into the base layer of the top 3 of the slope along the inside of the frame positioning support 7. After completion, use a tool to insert it into the cross groove 167 of the inner rod end 166 of the grounding pile 16. After rotating, take out the inner rod 168. Dig the first grouting trench 4 at the bottom 2 of the mine slope 1 and install a retaining plate on the inner edge of the first grouting trench 4. After laying a layer of sand and gravel on the bottom surface, put in the steel reinforcement support 13.

[0064] Step 4: Set up the positioning top frame 10 and place it at the front end of the frame positioning support 7 so that the frame beam 11 and the retaining net group 12 are placed vertically on the mine slope 1. After completion, insert the positioning rod 14 at the rear end of the positioning top frame 10 into the positioning hole 15 on the frame positioning support 7. Then, the positioning top frame 10 and the frame positioning support 7 are welded together by personnel to complete the initial fixation of the two.

[0065] Step 5: Personnel apply pressure to the frame beam 11 section by section from top to bottom using mechanical equipment, so that the frame beam 11 section bends and adheres to the slope under the action of the hinge joint 114, and extends the bottom end of the frame beam 11 into the first grouting groove 4. Personnel then weld and fix the bottom end of the frame beam 11 to the steel reinforcement support 13.

[0066] Step 6: Pour concrete grout into the first grouting tank 4 and the second grouting tank 8. The connection strength between the concrete reinforcement frame positioning support 7 and the positioning top frame 10 in the first grouting tank 4, and the connection strength between the bottom end of the concrete reinforcement frame beam 11 and the steel reinforcement support 13 in the second grouting tank 8 are used to determine the connection strength.

[0067] Step 7: Spray clean water evenly onto the mine slope 1 to maintain the vegetation. At the same time, the water seeps into the seepage groove 19 on the bottom side of the frame section 111 and comes into contact with the water-activated adhesive layer 18. When the water-activated adhesive layer 18 comes into contact with water, its hydrophobic skeleton shrinks and the hyperbranched polymer inside coagulates, thereby quickly removing the water from the surface of the matrix. The more hydrophilic catechol is exposed to the outside, thus making full contact with the matrix and producing an adhesion effect, fixing the frame section 111 part to the slope and realizing the reinforcement of the mine slope.

7. A frame beam structure for mine slope reinforcement according to claim 6, characterized in that: The flexible connection node (112) includes a hinge joint (114) and a rubber sleeve (113). The hinge joint (114) is installed at the end of the frame segment (111), and the hinge joints (114) between adjacent frame segments (111) are rotatably connected by a damping shaft (115). The rubber sleeve (113) is disposed outside the hinge joint (114), and the rubber sleeve (113) is bonded to the frame segment (111).

8. A method for reinforcing a frame beam structure for mine slope reinforcement, based on the frame beam structure for mine slope reinforcement described in claim 7, characterized in that... Includes the following steps: Step 1: Clean the slope, removing obvious debris and large stones; Step 2: Apply fertilizer and lime powder to initially solidify the slope soil, and sow vegetation seeds. The vegetation seeds are one or more of the following: perennial ryegrass, bermudagrass, tall fescue, ryegrass, and Kentucky bluegrass. Step 3: Erect a frame positioning support (7) at the top (3) of the mine slope (1). When erecting the support, drive the grounding pile (16) into the base layer of the top (3) of the slope along the inside of the frame positioning support (7). After completion, use a tool to insert it into the cross groove (167) of the end (166) of the grounding pile (16). Rotate and take out the inner rod (168). Dig the first grouting trench (4) at the bottom (2) of the mine slope (1). Install a retaining plate on the edge of the inner wall of the first grouting trench (4). After laying a layer of sand and gravel on the bottom surface, put in the steel reinforcement support (13). Step 4: Set up the positioning top frame (10) and place it at the front end of the frame positioning support (7), so that the frame beam (11) and the retaining net group (12) hang down on the mine slope (1). After completion, insert the positioning rod (14) at the rear end of the positioning top frame (10) into the positioning hole (15) on the frame positioning support (7). The positioning top frame (10) and the frame positioning support (7) are welded together by personnel to complete the initial fixation of the two. Step 5: Personnel apply pressure to the frame beam (11) section by section from top to bottom using mechanical equipment, so that the frame beam (11) section bends and attaches to the slope under the action of the hinge joint (114), and extends the bottom end of the frame beam (11) into the first grouting groove (4), and personnel weld and fix the bottom end of the frame beam (11) to the steel reinforcement support (13); Step 6: Pour concrete slurry into the first grouting tank (4) and the second grouting tank (8), and measure the connection strength between the concrete reinforcement frame positioning support (7) and the positioning top frame (10) in the first grouting tank (4) and the connection strength between the bottom end of the concrete reinforcement frame beam (11) and the steel reinforcement support (13) in the second grouting tank (8). Step 7: Spray clean water evenly onto the mine slope (1) to maintain the vegetation. At the same time, the water seeps into the seepage groove (19) on the bottom side of the frame section (111) and comes into contact with the water-induced adhesive layer (18). When the water-induced adhesive layer (18) comes into contact with water, its hydrophobic skeleton shrinks and the hyperbranched polymer inside condenses, thereby quickly removing the water from the surface of the matrix. The more hydrophilic catechol is exposed to the outside, thus making full contact with the matrix and producing an adhesive effect to fix the frame section (111) part to the slope, thereby achieving the reinforcement of the mine slope.
