[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1-Figure 6 As shown, the problem that the existing technology cannot autonomously and adaptively adjust the slurry output according to the change in the width of the crack can be solved by the following solution:

[0037] In this embodiment, the anti-deviation grouting device based on the treatment of cracks in construction engineering comprises a mobile body 1, an adjustable anti-deviation grouting mechanism 2 is installed on the mobile body 1, and the adjustable anti-deviation grouting mechanism 2 comprises a mounting plate 21, a moving block 22 is slidably connected to the mounting plate 21, and a grouting pipe 23 is fixedly connected to the moving block 22. By installing the grouting pipe 23 on the moving block 22, and the moving block 22 and the mounting plate 21 are slidably installed, so that during the grouting process of the mobile grouting pipe 23, the grouting pipe 23 synchronously moves left and right in the repair forward direction, so that the grouting pipe 23 can accurately fill the repair slurry into the crack;

[0038] A grout outlet 24 with a square structure is provided on the annular outer wall of the grouting pipe 23, and an anti-deflection column 25 with a conical structure at the end is movably installed on the grouting pipe 23. Through the anti-deflection column 25 with a conical structure at the end, the conical end of the anti-deflection column 25 is inserted into the crack, so that during the movement and grouting process of the grouting pipe 23, the conical surface of the anti-deflection column 25 is guided by the crack, and the rotation between the anti-deflection column 25 and the grouting pipe 23 can perform autonomous follow-up multi-directional movement according to the curved shape of the crack;

[0039] Ensure that the end of the anti-deviation column 25 is always located in the crack, effectively avoid the problem of deviation during the grouting process, and achieve accurate and efficient crack repair effect. The interior of the anti-deviation column 25 is fixedly connected with a limiting sleeve 26 that matches the grouting pipe 23. The different lengths of the grouting pipe 23 in the limiting sleeve 26 can realize the regulation of the size of the slurry outlet 24.

[0040] The anti-deflection column 25 is provided with a dust-cleaning multi-stage smoothing mechanism 3, which includes a material-filling sleeve 31 movably mounted on the anti-deflection column 25, and a material-blocking plate 32 is fixedly connected to the material-filling sleeve 31. The repair slurry is discharged into the anti-deflection column 25 through the slurry outlet 24 and then enters the crack for filling and repairing. The repair slurry is prevented from being diffused in large quantities by the material-blocking plate 32, thereby increasing the injection amount of the slurry into the crack.

[0041] The excess repair slurry in the crack enters the filling sleeve 31 in combination with the tapered end of the anti-deflection column 25, fills the inside of the filling sleeve 31 and is temporarily collected. When the anti-deflection column 25 moves, the anti-deflection column 25 reciprocates in combination with the change in the crack width, causing the internal volume of the filling sleeve 31 to change, which can further squeeze the repair slurry in the filling sleeve 31 into the wider crack to improve the filling effect.

[0042] A trowel plate 33 is slidably installed on one side of the baffle plate 32. As the baffle plate 32 moves, the slurry filling the crack is smoothed, and a plurality of <-shaped scraper strips 34 are equidistantly installed on the trowel plate 33 to scrape back the slurry overflowing from both sides of the crack and squeeze it into the crack, further improving the filling effect. A blowing seat 35 is installed on the baffle plate 32.

[0043] A slurry storage tank 11 is fixedly installed on the top of the mobile body 1 for storing crack repair slurry, and a delivery pipe 12 is connected between the slurry storage tank 11 and the grouting pipe 23. A suction pump 13 connected to the delivery pipe 12 is installed on the top of the mobile body 1 by bolts. The suction pump 13 draws the repair slurry in the slurry storage tank 11, injects it into the grouting pipe 23 through the delivery pipe 12, and then discharges it into the anti-deflection column 25 through the slurry outlet 24 and then enters the crack for filling and repair.

[0044] Two sets of guide seats 14 are welded on the top of the mobile body 1, and a U-shaped frame 27 is slidably connected between the guide seats 14. A screw rod threadedly connected to the U-shaped frame 27 is rotatably installed on one side of the guide seat 14, and a lifting motor driving the screw rod to rotate is installed on the guide seat 14 through bolts. When the ground cracks are treated, the lifting motor drives the screw rod to rotate, prompting the U-shaped frame 27 to move downward, and the tapered end of the anti-deflection column 25 is inserted into the ground crack;

[0045] The mobile body 1 moves and carries the tapered end of the anti-deviation column 25 to move in the cracks on the ground. When cracks on the building wall are treated, the mobile body 1 moves and carries the tapered end of the anti-deviation column 25 to move in the cracks on the ground. The lifting motor drives the screw rod to rotate, prompting the U-shaped frame 27 to rise and drive the tapered end of the anti-deviation column 25 to move in the cracks on the building wall, thereby realizing the repair of the cracks on the ground or the building wall.

[0046] An ear plate 28 is symmetrically fixed to one side of the mounting plate 21, and a rotating rod that rotates with the U-shaped frame 27 is fixed to the ear plate 28. Through the rotating connection between the mounting plate 21 and the U-shaped frame 27, the baffle plate 32 can be adjusted to a horizontal or vertical state according to cracks in the ground or building wall, thereby improving the application range of the device. The end of the rotating rod is fixedly connected to a limiting plate, and a limiting bolt is threadedly connected to the limiting plate. A plurality of limiting holes are provided on the U-shaped frame 27. After the mounting plate 21 is rotated to carry the baffle plate 32 in a horizontal or vertical state, the limiting bolt is rotated to connect its end with the limiting hole at the corresponding position, thereby completing the fixation of the adjusted position.

[0047] A return spring 29 is fixedly connected between the two sides of the moving block 22 and the mounting plate 21, which is used to assist the movement of the moving block 22 and improve the convenience of the multi-directional movement of the anti-deflection column 25. An auxiliary seat 210 is rotatably installed on the outer wall of the anti-deflection column 25. Compression springs 211 are fixedly connected between the two sides of the auxiliary seat 210 and the moving block 22 and the baffle plate 32. A limited block is fixedly connected to the grouting pipe 23 to limit the separation of the grouting pipe 23 and the anti-deflection column 25.

[0048] And a telescopic sleeve rod located inside the compression spring 211, the telescopic sleeve rod is used to increase the relative rotation between the moving block 22, the auxiliary seat 210 and the baffle plate 32, and the grouting pipe 23 and the anti-deflection column 25 are relatively moved before grouting, so that half of the grouting outlet 24 on the grouting pipe 23 is placed inside the limiting sleeve 26, and the anti-deflection column 25 is subjected to the compression elastic force of the compression spring 211 between the moving block 22 and the auxiliary seat 210. During the movement of the anti-deflection column 25 along the crack, the anti-deflection column 25 is prompted to autonomously follow the multi-directional movement according to the shape of the crack;

[0049] During the movement, when the crack width gradually decreases, the crack guiding anti-deflection column 25 moves closer to the mounting plate 21, so that the length of the grouting pipe 23 in the limiting sleeve 26 increases, prompting the limiting sleeve 26 to further increase the blocking area of ​​the slurry outlet 24, reducing the slurry discharge amount, and keeping the fluid flow rate inside the grouting pipe 23 unchanged, the size of the slurry outlet 24 is reduced to increase the slurry discharge rate, thereby increasing the filling effect of small-width cracks;

[0050] When the crack width gradually increases, the crack guiding anti-deflection column 25 moves away from the mounting plate 21, reducing the length of the grouting pipe 23 in the limiting sleeve 26, prompting the limiting sleeve 26 to reduce the blocking area of ​​the slurry outlet 24, increasing the slurry output, and thereby increasing the filling efficiency of large-width cracks.

[0051] Example 2: Please refer to Figure 4 ,and Figure 6-Figure 9 As shown, the problem that the slurry filling in the cracks is not compacted, making it difficult to fully fill the cracks with the slurry, thereby affecting the connection strength after the slurry solidifies, can be solved by the following solutions;

[0052] In this embodiment, a plurality of connecting cavities are equidistantly provided inside the material baffle plate 32, and air is discharged alternately through the plurality of connecting cavities to achieve continuous blowing treatment, and a plurality of air cavities penetrating one side of the material baffle plate 32 are provided on one side of the connecting cavity, and a knocking block 36 is provided inside the air cavity to seal and slide, and the plurality of knocking blocks 36 reciprocate in the corresponding air cavity and hit the trowel plate 33, causing the trowel plate 33 to carry the <-shaped scraper strip 34 to vibrate, thereby indirectly compacting the repair slurry in the crack and improving the compactness of the slurry filling.

[0053] The baffle plate 32 is provided with movable plates 37 with the same number as the connecting cavities, a support rod sliding with the baffle plate 32 is fixedly connected between the movable plate 37 and the knocking block 36, and a reset spring 38 is fixedly connected between the movable plate 37 and the baffle plate 32. The movable plate 37 is pulled away from the baffle plate 32 and then reset under the tensile elastic force of the reset spring 38, thereby hitting the trowel plate 33.

[0054] A U-shaped auxiliary frame 39 is fixedly connected to the movable plate 37, two groups of support plates are welded on the baffle plate 32, and a rotating shaft 310 is rotatably connected between the support plates. A cam 311 is fixedly connected to the rotating shaft 310 and is in sliding contact with the corresponding U-shaped auxiliary frame 39. The protrusions of the multiple cams 311 are oriented in different directions and are used to drive the multiple movable plates 37 to move alternately. A rotating motor for driving the rotating shaft 310 to rotate is installed on the support plate. The rotating motor drives the rotating shaft 310 to rotate. The rotating shaft 310 is combined with multiple cams 311, the U-shaped auxiliary frame 39 and the reset spring 38 to drive the movable plate 37 to reciprocate. The movable plate 37 drives multiple knocking blocks 36 to reciprocate and hit the trowel plate 33 through the support rod.

[0055] The free end of the rotating shaft 310 is fixedly connected to a winding plate, and a winding rod is fixedly connected to the winding plate. An L-shaped plate 312 that slides with the material blocking plate 32 is fixedly connected to the trowel plate 33. The L-shaped plate 312 is provided with a slot that slides with the winding rod. The rotating shaft 310 drives the winding plate to carry the winding rod to rotate circumferentially, and the winding rod slides in the slot to link the L-shaped plate 312 to cause the trowel plate 33 to move back and forth, further accelerating the efficiency of the <-shaped scraper strip 34 to scrape back and compact the repair slurry that seeps out of the crack to the outside on both sides, and then combined with vibration compaction, the filling compaction degree is further improved.

[0056] The baffle plate 32 is threadedly mounted with an air inlet check valve and an air outlet check valve in communication with the connecting cavity. An air outlet pipe 313 is fixedly connected between each air outlet check valve and the blowing seat 35. When the knocking block 36 moves away from the connecting cavity in the corresponding air cavity, its internal pressure decreases, and external gas is extracted through the air inlet check valve. When the knocking block 36 moves close to the connecting cavity, the extracted air is injected into the blowing seat 35 through the connecting cavity, the air outlet check valve and the air outlet pipe 313.

[0057] One side of the blowing seat 35 is provided with a plurality of air outlet holes which are in communication with the interior thereof at equal intervals. One side of the blowing seat 35 is arranged flush with one side of the material baffle plate 32. The air outlet holes on the blowing seat 35 are blocked by the wall or the ground, and the air outlet holes cannot be blocked at the cracks, thereby performing centralized blowing and cleaning treatment on the inside of the curved cracks to improve the repair quality.

[0058] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also proposes a method for using an anti-deviation grouting device based on crack treatment in construction engineering, comprising the following steps:

[0059] Step 1: According to the cracks on the ground or building wall, adjust the baffle plate 32 to a horizontal or vertical state, rotate the mounting plate 21 to carry the baffle plate 32 to a horizontal or vertical state, rotate the limit bolt to plug its end into the limit hole at the corresponding position, thereby completing the fixing of the adjusted position, and inject the crack repair slurry into the slurry storage tank 11;

[0060] Step 2: The tapered end of the anti-deflection column 25 is inserted into the crack of the building wall by moving the mobile body 1, or the lifting motor drives the screw rod to rotate, so that the U-shaped frame 27 moves downward, and the tapered end of the anti-deflection column 25 is inserted into the crack of the ground, and the baffle plate 32 is bonded to the building wall or the ground, and the compression spring 211 is compressed, so that the filling sleeve 31, the anti-deflection column 25 and the grouting pipe 23 move relative to each other, and half of the slurry outlet 24 on the grouting pipe 23 is placed inside the limiting sleeve 26;

[0061] The repair slurry in the slurry storage tank 11 is extracted by the suction pump 13, injected into the grouting pipe 23 through the feed pipe 12, and then discharged into the anti-deviation column 25 through the slurry outlet 24 and then enters the crack for filling and repairing. The baffle plate 32 prevents the repair slurry from spreading everywhere, and the excess repair slurry in the crack combines with the tapered end of the anti-deviation column 25 to enter the filling sleeve 31, fill the inside of the filling sleeve 31 and collect it temporarily;

[0062] Step 3: The lifting motor drives the screw rod to rotate, so that the U-shaped frame 27 rises and drives the tapered end of the anti-deviation column 25 to move in the crack of the building wall, or the mobile body 1 moves and carries the tapered end of the anti-deviation column 25 to move in the crack of the ground. Through the sliding of the moving block 22 and the rotation of the anti-deviation column 25, the anti-deviation column 25 can be driven to autonomously follow the multi-directional movement according to the shape of the crack during the movement of the anti-deviation column 25 along the crack to perform anti-deviation grouting treatment. With the help of the elastic force of the compression spring 211 between the auxiliary seat 210 and the moving block 22, and the tapered structure at the end of the anti-deviation column 25, the relative displacement distance between the grouting pipe 23 and the anti-deviation column 25 is autonomously adjusted according to the width of the crack.

[0063] Step 4: When the width of the crack gradually decreases, the anti-deflection column 25 moves toward the mounting plate 21, so that the length of the grouting pipe 23 in the limiting sleeve 26 increases, prompting the limiting sleeve 26 to further increase the plugging area of ​​the slurry outlet 24, reduce the slurry discharge amount, and keep the fluid flow rate inside the grouting pipe 23 unchanged, and reduce the size of the slurry outlet 24 to increase the slurry discharge rate, thereby increasing the filling effect of small-width cracks; when the width of the crack gradually increases, the anti-deflection column 25 moves away from the mounting plate 21, so that the length of the grouting pipe 23 in the limiting sleeve 26 decreases, prompting the limiting sleeve 26 to reduce the plugging area of ​​the slurry outlet 24, increase the slurry discharge amount, and thereby increase the filling efficiency of large-width cracks;

[0064] Step 5: During the grouting process of the mobile crack, the change of the crack width causes the anti-deflection column 25 to reciprocate, resulting in the change of the internal volume of the filling sleeve 31, which can further squeeze the repair slurry in the filling sleeve 31 into the wider crack, thereby improving the filling effect. The filled crack moves relatively to the trowel plate 33 area, and the rotating motor drives the rotating shaft 310 to rotate. The rotating shaft 310 is combined with multiple cams 311, U-shaped auxiliary frames 39 and reset springs 38 to drive the movable plate 37 to reciprocate. The movable plate 37 drives multiple knocking blocks 36 to reciprocate and hit the trowel plate 33 through the support rod, so that the trowel plate 33 carries the <-shaped scraper strip 34 to vibrate, thereby indirectly tamping the repair slurry in the crack. In addition, the rotating shaft 310 drives the surrounding plate to rotate circumferentially with the surrounding rod, and links the L-shaped plate 312 to cause the trowel plate 33 to reciprocate, so that the <-shaped scraper strip 34 scrapes back the repair slurry that seeps out of the crack to the outside on both sides, and combines with vibration tamping to improve the filling compactness;

[0065] Step six: When the knocking block 36 moves away from the connecting cavity in the corresponding air cavity, its internal pressure decreases, and the external gas is extracted through the air inlet check valve. When the knocking block 36 moves close to the connecting cavity, the extracted air is injected into the blowing seat 35 through the connecting cavity, the air outlet check valve and the air outlet pipe 313. The air outlet holes on the blowing seat 35 are blocked by the wall or the ground, and the air outlet holes cannot be blocked at the cracks, so that the inside of the cracks is blown and cleaned centrally to improve the repair quality. Moreover, by having multiple sets of cam 311 protrusions in different directions, multiple connecting cavities are prompted to discharge air alternately for continuous blowing treatment.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
