Description

Technical Field

[0001] This utility model relates to the field of filling mining technology, specifically to a filling and sealing retaining wall device. Background Technology

[0002] Before backfilling in the backfilling mining method, the first step is to seal the stope to isolate it from all external shafts and tunnels, preventing the backfill slurry from overflowing, which would dilute the ore and deteriorate the working environment. Secondly, appropriate water filtration facilities are needed to prevent water accumulation in the stope and the loss of cement components from the backfill.

[0003] In related technologies, four main types of retaining walls are used: block retaining walls, concrete structural retaining walls, wooden retaining walls, and reinforced flexible retaining walls. Block retaining walls have poor bending resistance, are prone to localized displacement and deformation leading to collapse and grout leakage, and require large transport volumes, involve high labor intensity, and have low water filtration efficiency. Concrete structural retaining walls have long curing cycles, are prone to grout leakage due to inadequate sealing at the tunnel walls, and have high construction costs, poor versatility, and are not reusable. Wooden retaining walls require high-quality timber, are time-consuming and labor-intensive to process, consume large quantities of timber, and have insufficient strength. Reinforced flexible retaining walls have complex construction processes, and their quality is difficult to guarantee. Utility Model Content

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-3 As shown, the filling and sealing retaining wall device of this utility model embodiment includes a fixing component and a supporting component.

[0029] The fixing assembly includes a mounting base 11, a fixing frame 12, and a sealing member 13. The fixing frame 12 is connected to the mounting base 11, and the sealing member 13 is located in the thickness direction of the fixing assembly (e.g., ...). Figure 1 The sealing member 13 is located between the mounting base 11 and the fixing frame 12 in the front-back direction, and its cross-sectional profile is adapted to the cross-sectional profile of the filling area 100 for sealing the filling area 100. The support assembly includes a support member 21 and a drive member 22. The support member 21 is connected to the mounting base 11, and the drive member 22 is connected to the support member 21. The support member 21 is in contact with the wall of the filling area. The support assembly has a supported state. In the supported state, at least a portion of the drive member 22 abuts against the support member 21 to make the support member 21 in sealed contact with the wall of the filling area.

[0030] Specifically, such as Figures 1-3 As shown, the fixing frame 12, the sealing element 13, and the mounting base 11 are arranged sequentially from left to right. The fixing frame 12 is connected to the mounting base 11 and can fix the sealing element 13 between them. The outline of the sealing element 13 is consistent with the longitudinal section outline of the filling area 100, so that the sealing element 13 can seal the filling area 100 when fixed between the fixing frame 12 and the mounting base 11. The support assembly is placed on the right side of the sealing element 13, and the support member 21 can contact the wall surface of the filling area 100, so that the support assembly can support the fixing assembly in the supported state, thereby ensuring the overall stability of the filling and sealing retaining wall device.

[0031] It is understandable that, such as Figures 1-3 As shown, the drive member 22 can control the contact force between the support member 21 and the wall of the filling area 100. That is, in the supported state, the drive member 22 can apply a force to the support member 21 in the direction of the wall of the filling area 100 so that the support member 21 can be fastened to the wall of the filling area 100, thereby realizing the function of supporting and fixing the assembly.

[0032] Preferably, such as Figure 2 As shown, the fixing frame 12 is I-shaped to increase the contact area between the fixing frame 12 and the sealing member 13, thereby improving the fixing strength of the sealing member 13.

[0033] It should be noted that the sealing component 13 can be geotextile, or other materials with functions such as waterproofing, seepage prevention, reinforcement, and protection. The driving component 22 can be a telescopic bracket, such as a cylinder or hydraulic cylinder; or a multi-segment rod-like structure connected by threads, so that the threaded fit can be adjusted by rotation to achieve the supporting state; it can also be a transmission device composed of a transmission mechanism, such as a gear and rack mechanism or a lead screw.

[0034] In other words, the filling and sealing retaining wall device of this utility model embodiment can use the mounting base 11 and the fixing frame 12 to fix the sealing component 13 between them, avoiding deformation of the sealing component 13 due to external forces during the sealing and filling of the filling area 100, which would result in poor sealing effect. In addition, the support component can be adjusted according to the usage environment to quickly realize the installation and disassembly of the filling and sealing retaining wall device, thereby improving construction efficiency.

[0035] In some embodiments, the fixing component further includes a fixing connector 14, which includes a first connector 141 and a second connector 142. The first end of the first connector 141 penetrates the fixing component in the thickness direction and is located on the side of the sealing member 13 away from the fixing frame 12. The second connector 142 is detachably connected to the first end of the first connector 141.

[0036] Specifically, such as Figures 1-3 As shown, the extension direction of the fixed connector 14 is consistent with the left and right direction. The right end of the first connector 141 passes through the fixed frame 12, the sealing member 13 and the mounting base 11 in sequence. The second connector 142 is connected to the right end of the first connector 141, thereby realizing the function of fastening and fixing the components.

[0037] It is understood that both the fixed frame 12 and the mounting base 11 are provided with connecting holes that match the first connecting member 141. The first connecting member 141 can be a threaded rod or a pin, and the second connecting member 142 is a component that matches the first connecting member 141, such as a nut.

[0038] In some embodiments, the mounting base 11 includes a mounting base 111 and a mounting rod 112, the mounting rod 112 being along the height direction of the fixing component (e.g., Figure 1 The mounting rod 112 extends through the mounting base 111 in the vertical direction, and its end is connected to the support member 21. The support member 21 is movable relative to the mounting rod 112. Multiple mounting rods 112 extend along the width direction of the fixing assembly (e.g., ...). Figure 2 Arranged at intervals in the left and right directions.

[0039] It is understandable that, such as Figures 1-3 As shown, multiple mounting rods 112 are arranged sequentially and spaced apart in the left and right directions to ensure the contact area with the sealing component 13. This allows the sealing component 13 to be fixed by the squeezing force between the fixing frame 12 and the mounting base 11 when the fixing frame 12 is connected to the mounting base 11.

[0040] In some embodiments, the support member 21 includes a support unit 211, which includes a support base 2111 and a support link 2114. The support base 2111 is connected to the mounting rod 112, the first end of the support link 2114 is connected to the support base 2111, and the second end of the support link 2114 is connected to the drive member 22.

[0041] It is understandable that, such as Figures 1-3 As shown, the upper end of the support link 2114 is connected to the support base 2111, and the driving member 22 is connected to the lower end of the support link 2114, so that when the driving member 22 drives the support link 2114 to move, it can apply a force toward the wall of the filling area 100 to the support base 2111, thereby ensuring that the support base 2111 can be firmly in contact with the wall of the filling area 100.

[0042] Preferably, there are multiple support units 211, and the multiple support units 211 are arranged at intervals along the circumference of the mounting base 11. It can be understood that, as... Figures 1-3 As shown, multiple support units 211 are evenly spaced along the circumferential direction of the mounting base 11, so that in the supported state, the support bases 2111 in multiple directions abut against the wall of the filling area 100, thereby improving the overall stability of the sealing device. Optionally, as... Figures 1-3 As shown, there are two support units 211, which are respectively arranged on the upper and lower sides of the mounting base 111.

[0043] In some embodiments, the support base 2111 has a slot 2112, the end of the mounting rod 112 is placed in the slot 2112, the side wall of the mounting rod 112 abuts against the side wall of the slot 2112, and there is a gap between the end of the mounting rod 112 and the bottom wall of the slot 2112.

[0044] It is understandable that, such as Figures 1-3 As shown, both the upper and lower ends of the mounting rod 112 are placed in the slot 2112. Since there is a gap between the mounting rod 112 and the bottom wall of the slot 2112, the driving member 22 can adjust the positional relationship between the support base 2111 and the mounting rod 112 when it drives the support base 2111 to provide support. That is, in the supported state, the support base 2111 can move away from the mounting rod 112 under the action of the driving member 22; when it needs to be removed, the support base 2111 can move closer to the mounting rod 112.

[0045] In some embodiments, the drive member 22 includes a drive screw 221 and a nut seat 222. The first end of the drive screw 221 is connected to the mounting base 111 and is rotatable relative to the mounting base 111. The nut seat 222 is threaded onto the drive screw 221. The second end of the support rod 2114 is rotatably connected to the nut seat 222, and the first end of the support rod 2114 is rotatably connected to the mounting base 111.

[0046] It is understandable that, such as Figures 1-3 As shown, the front end of the drive screw 221 is rotatably connected to the mounting base 111. Specifically, the mounting base 111 has a rotating hole, and the front end of the drive screw 221 is a rotating shaft (without threads). Therefore, the drive screw 221 can engage with the mounting base 111 through the rotating hole, and the drive screw 221 can rotate relative to the mounting base 111. The nut seat 222 is fitted onto the drive screw 221. During use, rotating the drive screw 221 causes relative rotation between the nut seat 222 and the drive screw 221, allowing the nut seat 222 to move along the length of the drive screw 221, thereby achieving the function of pressing or loosening the support base 2111.

[0047] In use, rotating the drive screw 221 clockwise moves the nut seat 222 toward the mounting base 111 (i.e., forward), thereby securing the support base 2111 to the wall of the filling area 100 via the support link 2114; then, rotating the drive screw 221 counterclockwise moves the nut seat 222 toward the rear, thereby contacting the preload applied by the support link 2114 toward the support base 2111, to facilitate subsequent disassembly.

[0048] Preferably, the drive member 22 further includes a screwing head 223 connected to the second end of the drive screw 221. The screwing head 223 has a insertion hole 2231 for inserting an extension for rotating the drive screw 221. It is understood that, as Figures 1-3 As shown, the screw head 223 is located at the rear end of the drive screw 221. The insertion hole 2231 of the screw head 223 can be used to insert an extension, such as a rigid rod, so that the drive screw 221 can be rotated by rotating the extension.

[0049] In some embodiments, the filling and sealing retaining wall device of this utility model further includes a filling airbag 3, which is placed between the side wall of the filling area 100 and the mounting rod 112. When the filling airbag 3 is inflated, the side wall of the filling airbag 3 abuts against the side wall of the filling area 100, the mounting rod 112 and the mounting base 111.

[0050] Specifically, such as Figures 1-3As shown, there are two airbags 3, which are located on the left and right sides of the mounting base 111 and respectively contact the left and right side walls of the filling area 100, so that the airbags 3 can fill the gap between the mounting rod 112 and the side wall of the filling area 100 when they are inflated.

[0051] It is understandable that, such as Figures 1-3 As shown, the extension direction of the support base 2111 is consistent with the left and right direction of the filling area 100, and there are likely gaps between the two ends of the support base 2111 and the left and right side walls of the filling area 100. Therefore, a filling airbag 3 is provided between the mounting rod 112 located on the leftmost and rightmost sides and the side wall of the filling area 100 to fill the gaps that exist between the fixing and to further ensure the sealing effect of the sealing device.

[0052] Preferably, the support base 2111 has an arcuate surface 2113, which is located on the side of the support base 2111 adjacent to the filling airbag 3, and the arcuate surface 2113 is concave towards the side away from the filling airbag 3. It is understood that, as Figures 1-3 As shown, the left and right side walls of the support base are both concave arc surfaces 2113, so that the filling airbag 3 can better contact the arc surface 2113 of the support base 2111 when it is inflated, further reducing the gap between the filling airbag 3 and the support base 2111 and ensuring the sealing effect.
