[0002] At present, there are many shallow foundation houses in old urban communities. Due to various factors, problems such as house inclination or uneven settlement have occurred, and deviation rectification construction is urgently needed.

[0003] At present, the shallow foundation house deviation rectification construction commonly adopts the soil excavation method. One of them is the water flushing method, that is, a hole is opened in the house structure bottom plate, and the soil body is excavated by using water flow impact.

DETAILED DESCRIPTION

[0031] like Figs. 1-6 As shown, the present invention provides a shallow foundation house correction device, including a crawler-type mobile mechanism 1 and a correction mechanism, and the correction mechanism is connected to the crawler-type mobile mechanism 1 with an adjustable inclination angle; it should be noted that the crawler-type mobile structure is a prior art, and reference can be made to the crawler chassis in the prior art, which will not be elaborated on here. At the same time, the specific structure of the correction mechanism being adjustable in angle connected to the crawler-type mobile mechanism 1 is that the connecting arm 2 is rotatably connected to the crawler-type mobile mechanism 1, and then the middle part of the connecting arm 2 is connected to the crawler-type mobile mechanism 1 through the hydraulic support rod 3, and then the inclination angle of the connecting arm 2 can be adjusted by telescopically adjusting the hydraulic support rod 3. Of course, other structures can also be used to realize the angle adjustable function of the connecting arm 2, which will not be elaborated on here. At the same time, it is preferred that the connecting arm 2 is length-adjustable, which can be achieved by hydraulic drive, and reference can be made to the telescopic arm in the prior art, which will not be elaborated on here. Of course, it is not difficult to understand that when the spiral drill rod 4 is perpendicular to the horizontal plane, the disturbance to the foundation is minimal and the correction effect is weakest. When the angle between the spiral drill rod 4 and the horizontal plane decreases, the disturbance to the foundation is enhanced and the correction effect is improved. When the inclination angle is large and the soil below the foundation is drilled directly, the correction effect is significant.

[0032] Specific, the correction mechanism includes a connecting arm 2, one end of the connecting arm 2 is connected to the crawler mobile mechanism 1, the other end of the connecting arm 2 is provided with a rectangular frame 6, the two sides of the rectangular frame 6 are symmetrically provided with a plurality of limiting holes 7, the inside of the rectangular frame 6 is provided with a plurality of sliding blocks 41 (the number is 4 in the specific embodiment), the two side faces of the plurality of sliding blocks 41 towards the limiting holes 7 are each provided with a mounting groove 12, the inside of the mounting groove 12 is provided with a reset spring 14, one end of the reset spring 14 is fixed to the bottom surface of the mounting groove 12, the other end of the reset spring 14 is provided with a limiting column 13, the side surface of the sliding block 41 is symmetrically provided with an L-shaped mounting plate, one end of the L-shaped mounting plate is fixed to the sliding block 41, the other end of the L-shaped mounting block 10 is located outside the rectangular frame 6, the L-shaped mounting block 10 is provided with an electromagnet 11, the middle part of the sliding block 41 is provided with a mounting hole 33, the upper side of the mounting hole 33 is provided with a U-shaped mounting frame 17, the opening end of the U-shaped mounting frame 17 is fixed to the sliding block 41, one side surface of the U-shaped mounting frame 17 is provided with a sliding table 18, the sliding table 18 is provided with a driving motor 19, the output end of the driving motor 19 is provided with a driving shaft 16, the driving shaft 16 passes through the mounting hole 33 and is arranged, one end of the driving shaft 16 passing through the mounting hole 33 is provided with a screw drill rod 4, one end of the screw drill rod 4 is fixed to the driving shaft 16.

[0033] The working principle of the above technical solution is:

[0034] According to the correction, the number of screw drill rods 4 required for soil excavation is determined, then the end of the screw drill rod 4 is connected to the driving rod, then the sliding block 41 is manually pushed to move, thereby changing the distance between adjacent sliding blocks 41, thereby adapting to the area requiring soil excavation, after the position of the sliding block 41 is adjusted in place, the electromagnet 11 connected to the screw drill rod 4 is controlled to be powered on through the control system (PLC), so that the electromagnet 11 sucks out the limiting column 13 from the mounting groove 12, that is, the end of the limiting column 13 is located in the limiting hole 7, thereby limiting the movement of the sliding block 41, so that the sliding block 41 is in a stable state, then the driving motor 19 and the sliding table 18 are started, so that the driving shaft 16 drives the screw drill rod 4 to continuously feed downward, realizing the soil excavation and correction operation, when the screw drill rod 4 feeds to the specified position, the screw drill rod 4 is extracted by resetting the sliding table 18 and reversing the driving motor 19. Of course, this technical solution is only for the soil excavation and correction step in the correction operation, as to whether it is necessary to backfill sandstone and grouting reinforcement after soil excavation, it is not described in detail here. Of course, it is not difficult to understand that the screw drill rod 4 is perpendicular to the horizontal plane, the disturbance to the foundation is minimal, and the correction effect is the weakest. The angle between the screw drill rod 4 and the horizontal plane decreases, the disturbance to the foundation increases, and the correction effect improves. When the inclination angle is large, the soil under the foundation is directly drilled, and the correction effect is significant.

[0035] The technical scheme can adjust the inclination angle of the screw drill rod 4, the feeding depth of each screw drill rod 4 and the action interval of each screw drill rod 4, so that the action point of the soil digging and deviation rectifying operation is more accurate, the deviation rectifying effect is improved, and the deviation rectifying efficiency is greatly improved when the several screw drill rods 4 operate together at the specified position to dig soil and rectify deviation.

[0036] In an implementable mode, the driving shaft 16 is provided with external threads at the end connected with the screw drill rod 4, and the end of the screw drill rod 4 is provided with a threaded sleeve 5, which is threadedly connected with the driving shaft 16. The driving shaft 16 and the screw drill rod 4 are connected through the threaded sleeve 5, which is convenient for disassembly and has good connection effect.

[0037] In an implementable mode, the U-shaped mounting frame 17 is symmetrically provided with rectangular grooves 15 on both sides, the rectangular grooves 15 are provided with T-shaped sliding blocks 20, one end of the T-shaped sliding block 20 is fixed on the driving motor 19, and the other end of the T-shaped sliding block 20 is in sliding contact with the side surface of the U-shaped mounting frame 17. The T-shaped sliding block 20 is limited in the upward and downward movement, which limits the driving motor 19, ensures the stability of the driving motor 19 during operation, and ensures the stability of the sliding table 18 driving the driving motor 19 to slide.

[0038] In an implementable mode, the bottom of the sliding block 41 is symmetrically provided with sliding grooves 8, the inner wall of the rectangular frame 6 is symmetrically provided with sliding channels 9, and the sliding grooves 8 are slidingly connected with the sliding channels 9. The sliding grooves 8 and the sliding channels 9 are connected in a manner that the sliding block 41 can only translate in the rectangular frame 6 and will not be separated from the rectangular frame 6, which ensures the sliding effect of the sliding block 41 and the installation stability of the remaining components on the sliding block 41.

[0039] In an implementable mode, the sliding block 41 is symmetrically provided with connecting rods 26 on one side of the length direction of the rectangular frame 6, one end of the connecting rod 26 is fixed on the sliding block 41, the other end of the connecting rod 26 is provided with a clamping groove 27, the opening direction of the clamping groove 27 is arranged towards the outer end of the mounting groove 12, the other side of the length direction of the rectangular frame 6 is symmetrically provided with a sliding through hole 28, the diameter of the sliding through hole 28 matches the diameter of the connecting rod 26, one end of the sliding through hole 28 is in communication with the inside of the mounting groove 12, a U-shaped groove 31 is arranged on one side of the sliding through hole 28 towards the limiting column 13, a clamping block 32 is arranged on the inner wall of the U-shaped groove 31, the clamping block 32 is fixed on the inner wall of the U-shaped groove 31, the upper surfaces of the symmetrically arranged L-shaped mounting blocks 10 are provided with first connecting blocks 21, the first connecting blocks 21 on the same side are provided with first traction ropes 25, the outer sides of the first connecting blocks 21 are provided with clamping blocks 39, the clamping blocks 39 are fixed on the first traction ropes 25, one end of the rectangular frame 6 is provided with a first fixed plate 23, the first fixed plate 23 is provided with a first rotating motor 22 and a first winding roller 24, and one end of the two first traction ropes 25 is connected with the first winding roller 24.

[0040] The working principle of the technical solution is as follows:

[0041] In the initial state, the sliders 41 are close to each other, at this time, the connecting rod 26 on one slider 41 enters the sliding hole 28 of the other slider 41, and under the action of the reset spring 14, the clamping block 32 on the limiting column 13 is pulled back into the clamping groove 27, that is, the positions between the adjacent sliders 41 are locked, and the plurality of sliders 41 realize synchronous movement operation.

[0042] When the worker selects the slider 41 to be used and determines the distance between the sliders 41, first, the rotating motor is operated to pull the traction rope to move, and due to the arrangement of the clamping block 39, the first traction rope 25 drives all the sliders 41 to move together until the slider 41 at the end is moved to the specified position, and then the electromagnet 11 on the slider 41 is energized to move the limiting column 13 outward into the limiting block, at this time, due to the outward movement of the limiting column 13, the clamping block 32 inside the slider 41 moves outward to disengage from the clamping groove 27, that is, when the first traction rope 25 drives the remaining plurality of sliders 41 to move, the position of the slider 41 at the end can be adjusted, and the position of the second slider 41 to be used can be adjusted to the position, and then the position of the third slider 41 can be adjusted, that is, by the action of the first rotating motor 22 and the first traction rope 25, the positions of the sliders 41 to be used can be accurately and quickly adjusted, avoiding the problem of high labor intensity and safety hazards caused by manually pushing the sliders 41 to move.

[0043] Of course, it should be noted that due to the arrangement of the clamping block 39, the first connecting block 21 is fixed to the first traction rope 25, so as to drive the slider 41 to move, and the length of the traction rope between the adjacent sliders 41 should be relatively long, which should be greater than the distance between the adjacent sliders 41 when they are close to the limiting position, that is, it can meet the distance movement requirement; at the same time, preferably, the electromagnet 11 should be started before the slider 41 moves to the specified position, that is, when the limiting block moves to the specified position, the limiting column 13 will immediately slide outward into the limiting hole 7 to realize the locking operation.

[0044] In an implementable manner, the side surface of the L-shaped mounting block 10 is provided with a second connecting block 37, a plurality of second connecting blocks 37 on the same side are provided with a second traction rope 38, the other end of the rectangular frame 6 is provided with a second fixed plate 34, the second fixed plate 34 is provided with a second rotating motor 35 and a second winding roller 36, and one end of the two second traction ropes 38 is tied to the second winding roller 36.

[0045] When the second rotating motor 35 drives the second traction rope 38 to move, it moves by pulling the outermost sliding block 41, and then pushes a plurality of sliding blocks 41 to the end of the rectangular frame 6, until the sliding blocks 41 are locked against each other, that is, the initial locking state of the sliding blocks 41 is quickly restored, and the spacing between the sliding blocks 41 is adjusted for next use. Of course, it is not difficult to understand that at this time the first rotating motor 22 should be in the state of paying off the line, and the electromagnet 11 should be sequentially powered off. The power-off time is when the connecting rod 26 on one sliding block 41 enters the mounting groove 12 of another sliding block 41, the electromagnet 11 provided on the other sliding block 41 is powered off, and then the reset spring 14 drives the clamping block 32 to reset to the clamping groove 27, realizing the locking operation. Of course, the end of the connecting rod 26 can also be wedge-shaped, so that after the clamping block 32 is reset, the clamping groove 27 can also contact the clamping block 32 to push the limiting column 13 up, realizing the connection and limiting of the clamping groove 27 and the clamping block 32. Of course, it can be set according to the actual situation.

[0046] In an implementable manner, the limiting column 13 is provided with a convex edge 30, and the inner wall of the mounting groove 12 is provided with a concave groove 29 outwardly, and the convex edge 30 is slidingly connected in the concave groove 29, which can avoid the rotation of the limiting column 13 and ensure the position of the clamping block 32, that is, ensure the connection effect of the clamping block 32 and the clamping groove 27.

[0047] A construction method for correcting deviation of a shallow foundation house comprises the following construction steps:

[0048] According to the house inclination monitoring data, the action area, action quantity, action angle, action spacing and action depth of the screw drill rod 4 in the correction equipment are confirmed. It is not difficult to understand that according to the monitoring data, the correction technology realized by the soil excavation method is a well-known technology for those skilled in the art, so the well-known specific derivation method of the action area, action quantity, action angle, action spacing and action depth of the screw drill rod 4 is not described here.

[0049] The correction equipment is driven to the action area, and the screw drill rod 4 is installed on the drive shaft 16, and then the inclination angle of the screw drill rod is adjusted;

[0050] The spacing between the screw drill rods 4 is adjusted, that is, the spacing between the sliding blocks 41 is adjusted, and after adjustment, the electromagnet 11 is controlled to be powered on, so that the electromagnet 11 sucks the end of the limiting column 13 into the limiting hole 7 to fix the position of the sliding block 41;

[0051] The sliding distance of each slide 18 is set respectively to control the feeding depth of each spiral drill rod 4. After the setting is completed, the correction equipment is started; the drive motor 19 and the slide 18 start working to control each spiral drill rod 4 to rotate to a specified depth at a specified position in the action area; different excavation depths can be achieved at different positions, thereby changing the refined deflection of the house body 40, thereby achieving precise control of the correction.

[0052] When the soil excavation work of the auger rod 4 of the deviation correction device is completed, the auger rod 4 is controlled to reverse and the slide 18 is reset, and the auger rod 4 is slowly withdrawn.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. 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.
