Description

Technical Field

[0001] The invention relates to the technical field of tunnel grouting equipment, and in particular to tunnel reinforcement grouting equipment. Background Art

[0002] Affected by geological conditions, loads, and waterproofing and drainage requirements, tunnels need to be reinforced as needed, among which grouting reinforcement is a commonly used tunnel reinforcement method. It injects grouting materials (such as cement slurry, chemical slurry, etc.) into the voids and pores in the tunnel structure to fill and solidify these voids, thereby improving the density and stability of the tunnel structure. Grouting reinforcement has the advantages of convenient construction and good reinforcement effect, so it is widely used in tunnel reinforcement operations.

[0003] For projects with high engineering safety requirements, such as tunnel reinforcement, it is necessary to ensure that the grouting liquid can fully fill the gaps and form a solid supporting structure. Therefore, it is necessary to use grouting liquid with a smaller particle size to ensure the uniformity and stability of the grouting liquid, improve the grouting effect, and ensure engineering safety.

[0004] However, when the existing tunnel grouting equipment is stirring the grouting liquid, the stirring structure is relatively simple, and the stirring process takes more time, which reduces the stirring efficiency of the equipment and thus increases the time required for the project. In addition, due to the singleness of the stirring rotation mode and the structure, the fineness of the grouting liquid after stirring is limited, which cannot meet the requirements of tunnel reinforcement construction well, thereby reducing the effect of tunnel reinforcement. Summary of the invention

[0005] In order to solve the technical problem that the existing tunnel grouting equipment proposed in the background technology has a relatively simple structure and stirring method when stirring the grouting liquid, which leads to low stirring efficiency of the grouting liquid and insufficient fineness of the grouting liquid, which ultimately affects the efficiency and effect of the reinforcement project, the present invention provides a tunnel reinforcement grouting equipment.

[0006] The present invention is implemented by adopting the following technical scheme: a tunnel reinforcement grouting device comprises a movable base and a stirring mechanism.

[0009] Through the above technical solution, the equipment can be moved by using the moving components, which is convenient for increasing the scope of use of the equipment. After arriving at the area to be reinforced in the tunnel, the stirring mechanism can be used to quickly stir and homogenize, greatly improving the stirring efficiency of the grouting liquid and saving construction time. The stirring mechanism can also improve the fineness of the mud liquid, and the fine grouting liquid usually has better fluidity and permeability, and can better adapt to complex geological conditions. By reducing the particle size of the grouting liquid, its fluidity and permeability can be improved, thereby improving the filling effect and consolidation strength of the grouting liquid.

[0015] As a further improvement of the above solution, the toggle assembly includes side bar 1, which is symmetrically fixed to both sides of rotating rod 1, and side bar 1 is staggered with side bar 2, and racks are evenly fixed on the same side of the side bars.

[0016] Through the above technical solution, the side bar 2 can slide horizontally relative to the inner slide groove to adapt to the relative horizontal displacement of the outer tube, and there is a gap at the connection between the side bar 1 and the inner slide groove, which facilitates the active meshing transmission between the rack and the gear 2.

[0017] As a further improvement of the above scheme, multiple groups of movable holes are symmetrically and evenly opened on both sides of the outer tube, and two circular ring protrusions are fixedly connected to the multiple groups of movable holes.

[0022] As a further improvement of the above scheme, the conveying system includes a conveying pipe, one end of which is fixedly connected to the bottom end of the stirring chamber, and the conveying pipe is connected to the inside of the stirring chamber, the other end of the conveying pipe is fixedly connected to a mud pump, the bottom end of the mud pump is fixedly connected to a fixing frame, and the fixing frame is fixedly installed on the top of the stirring chamber.

[0023] As a further improvement of the above solution, a connecting pipe is fixedly connected to the bottom end of the mud pump, and the outer wall of the other end of the connecting pipe is fixedly connected to the fixing frame.

[0024] Through the above technical solution, the grouting liquid that has been stirred can be transported to the tunnel area to be reinforced by using a mud pump, thereby achieving the reinforcement of the tunnel.

[0026] As a further improvement of the above scheme, the outer wall of the connection between the feed port and the stirring chamber is fixedly connected with side rod one and side rod two in sequence, and the same rotating rod two is relatively horizontally slidably connected on side rod one and side rod two. A spring is elastically connected between rotating rod two and the outer wall of the feed port, and the spring is wound around the outer wall of side rod one.

[0028] Compared with the prior art, the present invention has the following beneficial effects: (I) The present invention utilizes the coordinated action of the homogenizing component, the displacement component and the shifting component in the stirring mechanism to fully perform compound stirring on the grouting liquid inside the stirring cavity, so that the grouting liquid can be broken up and mixed more quickly, thereby greatly improving the stirring efficiency of the grouting liquid. In addition, the present invention can also accelerate the further refinement of the internal mud liquid with the cooperation of the stirring mechanism, effectively improving the fineness of the equipment, thereby utilizing the fine grouting liquid to better perform reinforcement operations on the tunnel area.

The feeding port 3 is connected to the stirring chamber 2, and a conveying system is fixedly connected to the other side of the top of the mobile base 1, and the conveying system is connected to the stirring chamber 2. Specifically, the conveying system transports the slurry that has been stirred inside to the grouting site.

[0036] The stirring mechanism includes a homogenizing component, a displacement component and a toggle component. The homogenizing component includes a turntable 1 5 and a turntable 2 6 which are symmetrically connected to the two ends of the stirring chamber 2. Specifically, a bearing is provided at the connection between the turntable 1 5 and the turntable 2 6 and the stirring chamber 2. The outer end of the turntable 1 5 is coaxially fixed with a stirring motor 4. The stirring motor 4 is fixed to the outer wall of the stirring chamber 2, and the output shaft of the stirring motor 4 is coaxially arranged with the turntable 1 5. The connection between the turntable 1 5, the turntable 2 6 and the stirring chamber 2 is provided with a sealing rubber ring. The inner side of the turntable 1 5 is rotatably connected with a ring block 10, and the ring block 10 is fixed to the inner wall of the stirring chamber 2. The inner side of the turntable 1 5 is symmetrically fixed with two annular protrusions 12, and the two annular protrusions 12 are both rotatably connected with annular recesses 13. The two annular recesses 1 3 is fixedly connected with a gear 14 at one end, and the other ends of the two annular recessed blocks 13 are fixedly connected with a rotating rod 15, the inner wall of the ring block 10 is fixedly connected with an internal gear 11, the internal gear 11 is meshed with the gear 14, the outer wall of the rotating rod 15 is symmetrically fixedly connected with a side bar 27, the side bar 27 is horizontally slidably connected with the outer tube 18, the inner wall of the outer tube 18 is uniformly provided with inner slide grooves 19, the side bar 27 is horizontally slidably connected with one group of the inner slide grooves 19, specifically, there are two groups of inner slide grooves 19, which are circumferentially provided on the inner wall of the outer tube 18, one group of the inner slide grooves 19 is horizontally slidably connected with the side bar 27, the outer wall of the outer tube 18 is uniformly symmetrically connected with a plurality of stirring plates 26, the plurality of stirring plates 26 are movable in the stirring chamber 2, and the movable areas of the plurality of stirring plates 26 will not overlap at the same time.

[0037] The implementation principle of a tunnel reinforcement grouting device in the embodiment of the present application is: After the equipment is moved to the tunnel repair work area by using the moving wheels and the pusher, the raw materials are introduced into the stirring chamber 2 from the feeding port 3 according to the required ratio, and the stirring motor 4 is started to synchronously drive the turntable 5 to drive the two groups of rotating rods 15 and another turntable 2 6 to stir in the stirring chamber 2. As the turntable 5 rotates, since the ring block 10 is fixedly connected to the stirring chamber 2, the turntable 5 uses the two annular protrusions 12 to drive the two groups of rotating rods 15 to rotate and move synchronously. Under the meshing connection between the inner gear 11 and the gear 14, the rotating rod 15 can drive the outer tube 18 to rotate and move back and forth horizontally, and drive the stirring plates 26 connected to the outer walls of the two groups of outer tubes 18 to stir the grouting liquid in the stirring chamber 2, so that the raw materials can be quickly dispersed and mixed, thereby accelerating the generation of grouting raw materials.

[0038] Example 2: Combination Figure 7 , Fig. 9 as well as Fig.10 Based on Example 1, this embodiment is further improved in that: The displacement assembly includes a connecting tube 21 symmetrically fixed to the inner wall of the turntable 2 6, wherein the connection between the connecting tube 21 and the rotating rod 15 can be a rotating connection or a non-contact setting, and a circulation groove is opened on the outer wall of the connecting tube 21, and a slider is slidably connected in the circulation groove, and a cylinder block 20 is fixed outside the slider. Specifically, the circulation groove is a peak-to-valley groove, which is used to guide the cylinder block 20 to slide horizontally back and forth by sliding the slider and the circulation groove.

[0039] The other side of the cylinder block 20 is fixedly connected to the outer tube 18. The two groups of connecting cylinders 21 are both sleeved with sealing cylinder bodies 22, and the two groups of sealing cylinder bodies 22 are both fixedly connected to the inner wall of the turntable 2 6. Since the outer tube 18 is driven to rotate synchronously by the rotating rod 15, the connecting cylinder 21 is relatively static with respect to the outer tube 18. The outer tube 18 can be used to drive the sealing cylinder body 22 and the connecting cylinder 21 to slide horizontally back and forth under the guidance of the circulation groove notch of the connecting cylinder 21, and the relative horizontal displacement change of the outer tube 18 and the rotating rod 15 can be realized, and multiple stirring plates 26 can be synchronously driven to stir the raw materials in the stirring chamber 2, thereby effectively increasing the contact surface of the stirring and ensuring the stirring effect.

[0040] A sealing rubber ring is provided at the connection between the sealing cylinder 22 and the outer wall of the outer tube 18 .

[0041] The implementation principle of a tunnel reinforcement grouting device in the embodiment of the present application is: As the two groups of rotating rods 15 rotate, the two groups of outer tubes 18 are used to drive the barrel block 20 to rotate synchronously. Since the turntable 26 and the turntable 15 synchronously drive the rotating rod 15 to rotate, the two groups of rotating rods 15 can also perform additional rotation to achieve relative stillness of the connecting barrel 21 and the outer tube 18. Therefore, under the sliding connection between the slider in the barrel block 20 and the circulating groove of the connecting barrel 21, the entire outer tube 18 and multiple stirring plates 26 are driven along the side strips 27 at the rotating rod 15 to perform reciprocating relative horizontal sliding, and finally the two groups of stirring plates 26 can better stir the grouting liquid in the stirring cavity 2, thereby accelerating the efficiency of homogenizing and stirring the grouting liquid.

[0042] Example 3: Combination Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 Based on Example 1 and Example 2, this embodiment is further improved in that: The toggle assembly includes a side bar 16, which is symmetrically fixed to both sides of the rotating rod 15, and the side bar 16 and the side bar 27 are staggered. Specifically, the two are not arranged in the same direction of the rotating rod 15 to avoid movement interference. A plurality of racks 17 are evenly fixed on the same side of the side bar 16. Specifically, the side bar 16 is located at another group of inner slide grooves 19 and reciprocates horizontally.

[0043] Multiple groups of movable holes are symmetrically and evenly opened on both sides of the outer tube 18, and annular protrusions 23 are fixedly connected to the multiple groups of movable holes. Rotating rods 24 are rotatably connected inside the multiple groups of annular protrusions 23.

[0044] The inner ends of the plurality of sets of rotating rods 24 are fixedly connected with gears 25 , and the plurality of sets of gears 25 are meshedly connected with the matching racks 17 .

[0045] The rotation range of the stirring plate 26 is -80° to 80°, and the multiple stirring plates 26 rotate synchronously, and the stirring plates 26 at the two outer tubes 18 will not interfere with each other. Furthermore, the multiple stirring plates 26 can change in sequential angles. Specifically, the stirring plates 26 from one direction to another direction can be tilted at a certain angle, such as 3°, in sequence, and it is ensured that the movable stirring plates 26 at the two outer tubes 18 will not interfere with each other.

[0046] The conveying system includes a conveying pipe 7, one end of which is fixedly connected to the bottom end of the stirring chamber 2, and the conveying pipe 7 is communicated with the inside of the stirring chamber 2, the other end of the conveying pipe 7 is fixedly connected to a mud pump 8, the bottom end of the mud pump 8 is fixedly connected to a fixing frame, and the fixing frame is fixedly installed on the top of the stirring chamber 2.

[0047] A connecting pipe 9 is fixedly connected to the bottom end of the mud pump 8, and the outer wall of the other end of the connecting pipe 9 is fixedly connected to the fixed frame, and the other end of the connecting pipe 9 can be connected to the grouting pipe for transporting the grouting liquid to the area to be grouting. Specifically, the connection method between the connecting pipe 9 and the grouting pipe includes but is not limited to threaded connection.

[0048] The implementation principle of a tunnel reinforcement grouting device in the embodiment of the present application is: As the outer tube 18 performs a relative horizontal reciprocating displacement, the multiple sets of racks 17 can drive the multiple sets of gears 2 25 to perform reciprocating periodic rotations during the relative displacement between the outer tube 18 and the rotating rod 15. The external stirring plate 26 can rotate and perform a composite motion of relative horizontal displacement under the rotation connection between the rotating rod 24 and the annular protrusion 23. It can also perform a periodic shift of -80° to 80°, further improving the stirring effect of the equipment, and can better refine the mud liquid and improve the fineness of the mud liquid. After completing the stirring operation, the mud pump 8 can be started to grout the mixed mud liquid along the delivery pipe 7 and the connecting pipe 9 to repair the tunnel area to be reinforced.

Specifically, a protrusion is provided at the side rod 2 34, and the protrusion is slidably connected to the rotary rod 2 35, and only supports the rotary rod 2 35 to reciprocate horizontally slide along the extension direction of the side rod 2 34. A spring 33 is connected between the rotary rod 2 35 and the outer wall of the feed port 3, and the spring 33 is wound around the outer wall of the side rod 1 31.

[0051] Specifically, the inclination direction of the bevel 30 is consistent with the rotation direction of the turntable 2 6, which is used to slide and abut the bevel 2 36, and the bevel 1 30 is inclined at the position consistent with the rotation direction and matches the bevel 2 36, so that when the bevel 1 30 is rotated to slide and abut with the bevel 2 36, the bevel 2 36 can be pushed to drive the bottom plate 32 to slide inward and periodically knock on the shell of the feed port 3.

[0052] The implementation principle of a tunnel reinforcement grouting device in the embodiment of the present application is: As the turntable 26 rotates, the rotary rod 29 is synchronously driven to rotate, and when the rotary rod 29 rotates to the top area, it will be able to slide under the sliding contact between the bevel 1 30 and the bevel 2 36, and cooperate with the bottom plate 32 under the relative horizontal sliding of the side rod 1 31 and the side rod 2 34, so that the inner end of the rotary rod 2 35 can be driven to knock against the outer wall of the feed inlet 3, and as the rotary rod 29 continues to rotate, after the sliding contact between the rotary rod 29 and the bottom plate 32 is released, it can return to its original position under the push of the spring 33, and complete the knocking of the outer wall of the feed inlet 3, so that the raw materials accumulated at the feed inlet 3 enter the stirring chamber 2, avoiding blockage at the feed inlet 3.
