Description

Technical Field

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

[0002] Tunnel crack grouting is a commonly used tunnel reinforcement technology. It mainly involves drilling holes at the crack locations, then pressing special grouting materials into the cracks through grouting nozzles, replacing water or air in several small cracks inside the cracks, and then filling the internal cracks. When the internal cracks are filled, the grouting material flows out from the opening of the cracks, filling the opening of the cracks, and then filling the entire crack to achieve the purpose of tunnel reinforcement.

[0003] However, in actual operation, when injecting slurry into the internal cracks, since the internal cracks are connected to the crack openings, and the crack openings are directly connected to the atmosphere, if the diameter of the cracks connecting the internal cracks and the openings is too large, then when the grouting slurry enters the openings, it will cause the grouting pressure in the grouting pipe to leak out from the openings, resulting in a large loss of grouting pressure, which will cause the diffusion effect of the slurry in the cracks to deteriorate, resulting in the problem of poor reinforcement effect on the tunnel.

[0029] like Figures 1 to 8 As shown, a tunnel reinforcement vehicle of the present invention is used for grouting reinforcement of tunnel cracks 15, including a mobile frame and a grouting mechanism, the grouting mechanism is rotatably connected to the upper end of the mobile frame, the grouting mechanism includes a plugging assembly, the plugging assembly includes two side plates 1 arranged in parallel, a fixed plate 2 is provided between the two side plates 1, the fixed plate 2 is arranged along the length direction of the side plate 1 and fixed on the inner wall of the side plate 1, a sliding plate 3 is provided below the fixed plate 2, both sides of the sliding plate 3 are slidably connected to the inner wall of the fixed plate 2, a plurality of sliding grooves are evenly arranged in the length direction of the sliding plate 3 and the fixed plate 2, a sliding rod 4 is provided in the sliding groove, the sliding rod 4 passes through the sliding grooves on the sliding plate 3 and the fixed plate 2, a top block 7 is provided at one end of the sliding rod 4 above the fixed plate 2, one end of the top block 7 is fixed to the end of the sliding rod 4, and a flexible plugging strip 1 is provided at the other end of the plurality of top blocks 7 4 (preferably a rubber strip), a flexible sealing strip 14 is detachably connected to the top block 7, a retaining ring 5 is provided on the portion of the slide bar 4 located below the fixed plate 2, the retaining ring 5 is fixed on the slide bar 4, a first spring 6 is provided between the retaining ring 5 and the sliding plate 3, the first spring 6 is sleeved on the slide bar 4, and the two ends of the first spring 6 are respectively fixed on the retaining ring 5 and the sliding plate 3, a mounting plate 8 is symmetrically provided on the outer side of the fixed plate 2, the mounting plates 8 are respectively fixed on the outer sides of the two side plates 1, at least one pushing element 10 is provided on the mounting plates 8, the pushing element 10 can be a linear telescopic motor or a hydraulic push rod 12, one end of the pushing element 10 is fixed on the mounting plate 8, the other end of the pushing element 10 is provided with an L-shaped pushing plate 9, one end of the L-shaped pushing plate 9 is fixed to the other end of the telescopic element, and the other end of the L-shaped pushing plate 9 is fixed to the edge of the sliding plate 3.

[0030] The working principle of the above technical solution is:

[0031] When a straight crack 15 appears on the curved surface of the tunnel, the device is first moved to the position of the crack 15, and then the pushing element 10 is controlled to work, so that the pushing element 10 drives the L-shaped push plate 9 to move, and then squeezes the first spring 6. The squeezed first spring 6 will squeeze the retaining ring 5, and then push the slide bar 4 to move toward the surface of the crack 15 of the tunnel, so that the flexible sealing strip 14 set on the top block 7 is in close contact with the surface of the crack 15 of the tunnel, thereby achieving sealing. During grouting, the slurry injected into the crack 15 will not be discharged from the opening position of the crack 15, ensuring that the grouting pressure enhances the diffusion effect of the slurry in the crack 15. Of course, this solution cannot absolutely seal the opening, and grouting pressure loss will still occur from small gaps, but a small amount of pressure loss will not have a significant impact on the grouting effect.

[0032] It is not difficult to understand that in the present technical solution, the advantage of the setting of the first spring 6 is that the L-shaped push plate 9 can be used to drive a number of slide bars 4 to press against the tunnel. At the same time, since the tunnel is generally an arc-shaped surface, the movement of the slide bars 4 when pressing against each other is not constant. Therefore, the first spring 6 can be compressed to compensate for the position of the slide bars 4 with small movement, so that a number of slide bars 4 can adapt to the pressing of the arc-shaped surface. At the same time, the pressing torque of the end of each slide bar 4 can be guaranteed to enhance the blocking effect. That is, with this setting, any arc-shaped surface can be formed between a number of top blocks 7 to adapt to the blocking operation during grouting of linear cracks 15 in the tunnel.

[0033] In one practicable manner, grooves 11 are provided on both sides of the top block 7 facing the side plate 1, a column 13 is provided in the groove 11, a push rod 12 is also provided in the groove 11, one end of the push rod 12 is slidably connected to the column 13, the other end of the push rod 12 passes through the side plate 1 and is slidably connected to the side plate 1, and a locking element for limiting the position of the push rod 12 is provided at the portion of the side plate 1 where the push rod 12 is slidably connected. The locking element can be a limit pin slidably set on the mounting plate 8, and a limit hole set on the push rod 12.

[0034] By sliding the push rod 12, the top block 7 can be pushed to move horizontally, and then the slide bar 4 can be pushed to move in the slide groove, and then the relative position of each top block 7 and the slide groove can be adjusted, and then an arc distribution can be formed between each top block 7, so as to adapt to the blocking of the arc cracks 15 (curved cracks 15) on the tunnel. It is not difficult to understand that the push rod 12 is slidably connected to the column 13, that is, the sliding of the top block 7 when it is pressed against the tunnel will not interfere with the push rod 12. Furthermore, it is not difficult to understand that when several top blocks 7 are distributed in an arc shape, the top blocks 7 may be staggered to form gaps after staggering. At this time, the extrusion of the flexible sealing strip 14 will not be completely covered. At this time, the flexible sealing strip can be extruded by setting an arc plate at the end of the top block 7. The area of ​​the arc plate is larger than the area of ​​the end of the top block 7, so it can act on the flexible sealing strip 14, and then the top block 7 acts on the arc plate to press the flexible sealing strip 14. Of course, the layout of the flexible sealing strip 14 is consistent with the direction of the crack 15.

[0035] In one practicable manner, the grouting mechanism also includes a grouting component and a suction component. The grouting component is used to grout into the cracks 15 of the tunnel, and the suction component is used to suck out impurities and seepage water in the cracks 15 of the tunnel before grouting. The grouting component includes a grouting pump 27 and a grouting pipe 28, one end of the grouting pipe 28 is connected to the output end of the grouting pump 27, and the suction component includes a suction pump 29 and a suction pipe 30, one end of the suction pipe 30 is connected to the input end of the suction pump 29.

[0036] After plugging and before grouting, the water and impurities inside the crack 15 are first sucked out from the lower end of the crack 15 on the tunnel through the suction pipe 30, so as to discharge the infiltrated water in the crack 15 and improve the diffusion effect of the slurry during subsequent grouting (the infiltrated water is not easily compressed and will affect the diffusion of the slurry). At the same time, it is not difficult to understand that the setting and working principle of the grouting component and the suction component are prior art and will not be elaborated on here.

[0037] In one practicable manner, at least one sliding through hole 32 is provided in the middle of one end of the top block 7 that contacts the tunnel, a limiting rod 33 is provided in the sliding through hole 32, one end of the limiting rod 33 is slidably connected in the sliding through hole 32, a top plate 36 is universally provided on the other end of the limiting rod 33, the top plate 36 is detachably universally connected to the end of the limiting rod 33, a stopper 35 is provided on the limiting rod 33 below the top plate 36, the stopper 35 is fixed on the limiting rod 33, a second spring 34 is provided between the stopper 35 and the top block 7, the second spring 34 is sleeved on the limiting rod 33, and the two ends are respectively fixed to the ends of the stopper 35 and the top block 7.

[0038] The universally arranged top plate 36 is preferably arranged in an arc shape. The advantage of this is that the top plate 36 can be replaced to further adapt to the curvature of the tunnel surface, so that the top plate 36 can squeeze and seal the flexible blocking strip 14 more closely. It is not difficult to understand that the arrangement of the second spring 34 and other components also compensates for the displacement of the limit rod 33 through the second spring 34. When a plurality of top plates 36 are arranged on the same top block 7, the plurality of limit rods 33 can be displaced to different lengths, so that the top plate 36 is arc-fitted to the tunnel surface, further improving the tightening effect on the flexible blocking strip 14. Of course, it is not difficult to understand that by replacing top plates 36 with different aspect ratios, each staggered top block 7 can also cover and tighten the curved arc-shaped blocking strip.

[0039] In one practicable manner, the mobile frame includes two parallel sliding frames 16 (including a frame body and bottom rollers, which is the prior art and will not be described in detail here), a plurality of connecting beams 17 are provided on the inner side of one end of the two sliding frames 16, and the two ends of the connecting beams 17 are respectively fixed on the inner side surfaces of the two sliding frames 16, a rotating sphere 18 is provided in the middle of the two sliding frames 16, and a connecting rod 31 is symmetrically provided on the rotating sphere 18, one end of the connecting rod 31 is rotatably connected to the rotating sphere 18, and the other end of the connecting rod 31 is fixed on the inner side surface of the sliding frame 16, a columnar groove is provided in the middle part above the rotating sphere 18, and the grouting mechanism is connected in the columnar groove, and a locking assembly for limiting the rotation position of the rotating sphere 18 is provided on the sliding frame 16.

[0040] In one feasible manner, a columnar rod 23 is provided in the columnar groove, one end of the columnar rod 23 is rotatably connected in the columnar groove, a support plate 24 is provided on the other end of the columnar rod 23, a plurality of lifting elements 26 are provided on the support plate 24, one end of the lifting element 26 is fixed on the support plate 24, and the other end of the lifting element 26 is fixed on the mounting plate 8, and the lifting element 26 is used to change the height of the grouting mechanism.

[0041] One end of the sliding frame 16 is open to avoid interference with the rotation of the grouting mechanism installed on the rotating sphere 18, that is, the grouting assembly can be rotated from the top position of the tunnel to the bottom position of the tunnel, and then the grouting mechanism can cover any position of the inner wall of the tunnel by moving and reversing the direction, and then the installation direction of the grouting mechanism is rotated in conjunction with the columnar rod 23 to be rotatably connected to the columnar groove, so that the plugging assembly can plug the vertically distributed cracks 15 and the horizontally distributed cracks 15, thereby realizing the plugging grouting operation of the cracks 15 at any position of the tunnel. It is not difficult to understand that the force on the columnar rod 23 is mostly vertical, so it will not rotate when it is stressed. Of course, the rotation of the columnar rod 23 can also be restricted by setting a block in the middle of the columnar rod 23 and setting a clamping groove 11 on the upper part of the columnar groove so that the block is located in the clamping groove 11. The lifting element 26 is arranged on the support plate 24, and the support plate 24 is arranged on the columnar rod 23. That is, when the rotating sphere 18 rotates, it can drive the support plate 24, the lifting element and the entire grouting mechanism to rotate, thereby facilitating the adjustment of the blocking position during grouting. At the same time, the lifting element 26 can be a hydraulic rod, the purpose of which is to change the height of the grouting mechanism so that it can perform grouting reinforcement operations on tunnel cracks 15 at different heights.

[0042] In one practicable manner, the locking assembly includes a plurality of card slots 19 arranged on the surface of the rotating sphere 18, and the plurality of card slots 19 are arranged perpendicular to the sliding frame 16 and are evenly distributed on the rotating sphere 18. A card plate 20 is provided between the two sliding frames 16, and both ends of the card plate 20 are slidably connected to the sliding frame 16. A fixed block 21 is also provided on the sliding frame 16 outside the end of the card plate 20, and the fixed block 21 is fixed to the sliding frame 16. A third spring 22 is provided between the fixed block 21 and the end of the card plate 20, and both ends of the third spring 22 are respectively fixed to the end of the card plate 20 and the fixed block 21.

[0043] After the rotating sphere 18 rotates, the position of the rotating sphere 18 can be fixed by inserting the card plate 20 into the card slot 19 at the corresponding position, and then the rotation angle of the grouting mechanism can be fixed, which is convenient for subsequent grouting operations. Of course, the third spring 22 is provided so that the card plate 20 can be tightly pressed against the card slot 19, and also so that the card plate 20 can be removed by compressing the third spring 22. The sliding method of the card plate 20 and the sliding frame 16 is that a rectangular groove with the same height as the card plate 20 is provided on the sliding frame 16. The card plate 20 can slide in the rectangular groove, but the rectangular groove can limit the rotation of the card plate 20.

[0044] In one practicable manner, an external thread is provided on the columnar rod 23, two locking nuts 25 are provided on the columnar rod 23, the columnar rod 23 passes through the middle of the support plate 24, and the support plate 24 is located between the two locking nuts 25. In this arrangement, the position of the support plate 24 on the columnar rod 23 can be changed by adjusting the position of the locking nut 25, and the height of the grouting mechanism can be further changed, so that the height adjustment range is larger to adapt to tunnels of different heights.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
