Description

Technical Field

[0002] Micro pile is a foundation reinforcement technology used for composite foundation treatment. It is mainly used for the treatment of surface or deep silty clay, silty, sandy soil layers and other foundations. Micro pile is a pile foundation with a small diameter (usually less than 300mm). It is a composite foundation treatment method that uses a small pile body of concrete poured through a vibrating pipe sinking tube and a certain number of gravel piles. It is suitable for various soft soil areas, especially the valley soft soil foundation where traditional mixing pile equipment cannot penetrate thin sand layers and lens-shaped soft soil foundations.

[0003] Therefore, based on the actual construction of existing micropiles, a steel pipe is inserted into a pre-laid foundation, and then concrete and other reinforcing materials are poured into the steel pipe.

The inclination of vertical piles shall not exceed 1%. At the same time, the inclination of inclined piles shall not exceed 2‰, and the inclination of horizontal piles shall not exceed 1‰.

[0021] By the above-mentioned structure being provided, the micro pile pipe 1 can be vertically installed in the composite foundation, and the installation angle can be detected during the installation process. Specifically, when the micro pile pipe 1 needs to be vertically installed in the composite foundation, one end of the detection device 3 is moved to the installation position of the micro pile pipe 1 by the handle 8, and the bottom of the mounting frame 7 is inserted thereunder, and one of the adjusting bolts 10 is rotated at this time, and the adjusting bolt 10 rotates to drive the damping gear 13 thereon to rotate, and the damping gear 13 rotates to drive a plurality of damping gears 13 to rotate, and the plurality of damping gears 13 rotate to drive a plurality of adjusting bolts 10 to rotate, so that the rubber pads at the tops of the plurality of adjusting bolts 10 and the horizontal ring 9 are aligned. External separation, at this time, under the action of the counterweight 2, the horizontal circle 9 rotates inside the mounting frame 7, so that the top of the horizontal circle 9 is parallel to the horizontal plane, and the adjusting bolt 10 is rotated in the opposite direction at this time, so that a plurality of rubber pads abut against the outside of the horizontal circle 9 to fix the horizontal circle 9, and at the same time, the horizontal circle 9 drives the mounting shell 11 to be parallel to the horizontal plane, and at this time, the axis center angle of the two sliding sleeves 34 coincides with the installation axis center angle of the micro pile pipe 1, and the angle adjustment is completed, and at this time, the micro pile pipe 1 is passed through the two sliding sleeves 34, and the micro pile pipe 1 is installed, and when the micro pile pipe 1 tilts during the installation process, the axis center of the two sliding sleeves 34 will follow the axis center tilt of the micro pile pipe 1; The top of the mounting shell 11 is fixedly connected with an arc plate 21, one side of the arc plate 21 is fixedly connected with a plurality of angle adjustment teeth 22, the top of the horizontal ring 9 is fixedly connected with an angle adjustment frame 16, the internal rotation of the angle adjustment frame 16 is connected with an angle adjustment wheel 17, one end of the angle adjustment wheel 17 is fixedly connected with an angle adjustment button 18; The other end of the angle adjustment wheel 17 is threadedly screwed with a clamping bolt 20, and one side of the angle adjustment frame 16 is fixedly connected with a support frame 19, which is compatible with the clamping bolt 20.

[0022] Further, in the above scheme, by the above-mentioned structure that is provided, the micropile pipe 1 can be installed according to the installation angle required for the micropile pipe 1, and the angle during the installation process is detected. Specifically, when it is necessary to tilt the micropile pipe 1 with the composite foundation at a specific angle, the horizontal circle 9 is first adjusted to be parallel to the horizontal plane and fixed, and the clamping bolt 20 is screwed at this time, and one side of the clamping bolt 20 is gradually separated from the bracket 19. At this time, the angle adjustment button 18 is rotated, and the angle adjustment button 18 rotates to drive the angle adjustment wheel 17 to rotate, and the angle adjustment wheel 17 rotates and engages with a number of angle adjustment teeth 22 to drive the installation shell 11 to slide inside the horizontal circle 9, thereby adjusting the angle of the installation shell 11.

When the angle adjustment is completed, the clamping bolt 20 is screwed in the opposite direction so that one side of the clamping bolt 20 is abutted against one side of the bracket 19.

[0023] A height adjustment mechanism 5 is used for adjusting the distance between the two sliding sleeves 34 in proportion to the length of the micropile pipe 1. The height adjustment mechanism 5 includes a height adjustment frame 14 that is rotatably connected to the top of the mounting shell 11. The interior of the height adjustment frame 14 is rotatably connected to a bidirectional threaded rod 24. The external threads of the bidirectional threaded rod 24 are screwed to two sliders 31. The two sliders 31 are respectively rotatably connected to the exterior of the adjacent sliding sleeves 34. The height adjustment mechanism 5 also includes a first mounting rod 47 fixedly connected to the top of the mounting shell 11, the top of the first mounting rod 47 is rotatably connected to the first mounting sleeve 26, the internal thread of the first mounting sleeve 26 is screwed with the first mounting head 27, the internal rotatably connected to the universal rod 28, the height adjustment frame 14 is fixedly connected to the top of the universal rod 28, the top of the first mounting head 27 is fixedly connected to the limit spring 29, the top of the limit spring 29 is fixedly connected to the bottom of the height adjustment frame 14, the top of the first mounting head 27 is fixedly connected to the protective sleeve 30, the top of the protective sleeve 30 is fixedly connected to the bottom of the height adjustment frame 14, and the top of the bidirectional threaded rod 24 is fixedly connected to the height adjustment button 25; One side of the slider 31 is rotatably connected to a telescopic rod 32, and both ends of the telescopic rod 32 are fixedly connected to ball heads 35. The ball heads 35 at both ends of the telescopic rod 32 are respectively rotatably connected to the inside of the adjacent slider 31 and the sliding sleeve 34. One side of the slider 31 is fixedly connected to a rejuvenating spring 33, and one end of the rejuvenating spring 33 is fixedly connected to one side of the adjacent sliding sleeve 34.

[0024] By the above-mentioned structure provided, the spacing of the two sliding sleeves 34 can be shortened by multiples according to the length of the micropile pipe 1, so as to facilitate the angle observation of the micropile pipe 1 in the later stage. Specifically, the micropile pipe 1 is of known length before construction. At this time, by rotating the height adjustment knob 25, the rotation of the height adjustment knob 25 drives the two-way threaded rod 24 to rotate, and the rotation of the two-way threaded rod 24 drives the two sliders 31 to move away from or close to each other, and the spacing of the two sliding sleeves 34 is controlled to be shortened by multiples of the length of the micropile pipe 1. At this time, the tilted state of the micropile pipe 1 can completely appear between the two sliding sleeves 34; More specifically, during the process of the micro-pile tube 1 tilting, the two aftertaste springs 33 are extended or compressed, the two telescopic rods 32 are extended or compressed, and the four ball heads 35 are all rotatably connected to the inside of the sliding sleeve 34 or the slider 31, so that the force during the tilting process of the micro-pile tube 1 is released and stored. At the same time, during the process of the micro-pile tube 1 tilting, the universal rod 28 rotates inside the first mounting head 27, and in this process the tilting force is released and stored through the limit spring 29, so that the micro-pile tube 1 will not be unable to eliminate stress when tilting at any angle.

[0025] An observation mechanism 6 is used to observe the tilt state of the micro pile pipe 1. The observation mechanism 6 includes a transparent tube 40 rotatably connected to the top of the mounting shell 11. A connecting rope 41 is arranged inside the transparent tube 40. Both ends of the connecting rope 41 are fixedly connected to a first permanent magnet 42. The top and bottom of the two sliding sleeves 34 are respectively fixedly connected to an extension rod 43. One end of the extension rod 43 is fixedly connected to a second permanent magnet 44. The two second permanent magnets 44 are magnetically adsorbed to the adjacent first permanent magnets 42. The transparent tube 40 is arranged at the middle position of the two sliding sleeves 34 so that the magnetic adsorption force of the two first permanent magnets 42 is the same as that of the two second permanent magnets 44. The observation mechanism 6 also includes a second mounting rod 15 fixedly connected to the top of the mounting shell 11, the top of the second mounting rod 15 is rotatably connected to a second mounting sleeve 36, the internal thread of the second mounting sleeve 36 is screwed with a second mounting head 37, the top of the second mounting head 37 is rotatably connected to a rotating head 38, the top of the rotating head 38 is fixedly connected to a mounting rod 39, a transparent tube 40 is fixedly connected to the top of the mounting rod 39, the outside of the transparent tube 40 is rotatably connected to a swivel 45, and the bottom of the swivel 45 is fixedly connected to a vertical needle 46.

[0026] By the above-mentioned structure that is provided, the tilted state of the micropile pipe 1 inside the composite foundation can be observed easily. Specifically, when the micropile pipe 1 tilts, the two sliding sleeves 34 follow the micropile pipe 1 to tilt. At this time, the extension rod 43 on the sliding sleeve 34 follows and moves and drives the second permanent magnet 44 to move. The second permanent magnet 44 moves and drives the two first permanent magnets 42 inside the transparent tube 40 to follow the close second permanent magnet 44 to move. Because the two are pulled by the connecting rope 41, at this time, the two first permanent magnets 42 move and rotate, and drive the connecting rope 41 to move and rotate. The connecting rope 41 at this time is identical with the tilted state, tilt angle and tilted position of the micropile pipe 1 inside the composite foundation, and the tilted moving position of the micropile pipe 1 needs to extend the moving distance of the connecting rope 41 by multiples according to the length of the micropile pipe 1 to obtain. At the same time, by rotating the swivel 45, the swivel 45 rotates and drives the vertical pin 46 to rotate, so that it can be quickly seen at what height the micropile pipe 1 tilts by the vertical pin 46 and the connecting rope 41, which is convenient for later maintenance and maintenance.

[0027] The working principle of the present invention is as follows: when the micro pile pipe 1 needs to be vertically installed in the composite foundation, at this time, one end of the detection device 3 is moved to the installation position of the micro pile pipe 1 through the handle 8, and the bottom of the mounting frame 7 is inserted into the bottom, and at this time, one of the adjusting bolts 10 is rotated, and the adjusting bolt 10 rotates to drive the damping gear 13 thereon to rotate, and the damping gear 13 rotates to drive a plurality of damping gears 13 to rotate, and the plurality of damping gears 13 rotate to drive a plurality of adjusting bolts 10 to rotate, so that the rubber pads on the tops of the plurality of adjusting bolts 10 are separated from the outside of the horizontal ring 9, and at this time, under the action of the counterweight 2, the horizontal ring 9 is installed. The internal rotation of the frame 7 makes the top of the horizontal circle 9 parallel to the horizontal plane, and the adjusting bolt 10 is rotated in the opposite direction at this time, so that the rubber pads are abutted against the outside of the horizontal circle 9 to fix the horizontal circle 9. At the same time, the horizontal circle 9 drives the installation shell 11 to be parallel to the horizontal plane. At this time, the axis angle of the two sliding sleeves 34 coincides with the installation axis angle of the micropile pipe 1, and the angle adjustment is completed. At this time, the micropile pipe 1 is passed through the two sliding sleeves 34, and the micropile pipe 1 is installed. When the micropile pipe 1 tilts during the installation process, the axis of the two sliding sleeves 34 will follow the axis tilt of the micropile pipe 1; When it is necessary to tilt the micropile pipe 1 with the composite foundation at a specific angle, the horizontal circle 9 is first adjusted to be parallel to the horizontal plane and fixed, and the clamping bolt 20 is screwed at this time, and one side of the clamping bolt 20 is gradually separated from the bracket 19, and the angle adjustment knob 18 is turned at this time, and the angle adjustment knob 18 rotates to drive the angle adjustment wheel 17 to rotate, and the angle adjustment wheel 17 rotates and engages with a plurality of angle adjustment teeth 22 to drive the mounting shell 11 to slide inside the horizontal circle 9, thereby adjusting the angle of the mounting shell 11. During the adjustment process, the adjustment angle can be monitored in real time by the angle meter 23. When the angle adjustment is completed, the clamping bolt 20 is screwed in the opposite direction to make one side of the clamping bolt 20 abut against one side of the bracket 19. When the angle adjustment is completed, the first mounting head 27 is inserted into the first mounting sleeve 26, and the first mounting sleeve 26 is rotated to fix the first mounting head 27 inside the first mounting sleeve 26. At the same time, the second mounting head 37 is inserted into the second mounting sleeve 36, and the second mounting sleeve 36 is rotated to fix the second mounting head 37 inside the second mounting sleeve 36. At this time, the installation of the height adjustment mechanism 5 and the observation mechanism 6 is completed; The micropile pipe 1 is of known length before construction. At this time, by rotating the height adjustment knob 25, the rotation of the height adjustment knob 25 drives the bidirectional threaded rod 24 to rotate, and the rotation of the bidirectional threaded rod 24 drives the two sliders 31 to move away from or close to each other, and the spacing between the two sliding sleeves 34 is controlled to be shortened by a multiple of the length of the micropile pipe 1. At this time, the tilted state of the micropile pipe 1 can completely appear between the two sliding sleeves 34; During the process of micro pile pipe 1 tilting, two aftertaste springs 33 are stretched or compressed, two telescopic rods 32 are stretched or compressed, and four ball heads 35 are all rotatably connected to the inside of sliding sleeve 34 or slider 31, so that the force during the process of micro pile pipe 1 tilting is released and stored. Meanwhile, during the process of micro pile pipe 1 tilting, universal rod 28 is rotated inside first mounting head 27, and the tilting force is released and stored by limit spring 29 during this process, so that the situation that stress cannot be eliminated will not occur when micro pile pipe 1 tilts at any angle. When micro pile pipe 1 tilts, two sliding sleeves 34 follow micro pile pipe 1 to tilt, at this moment, extension rod 43 on sliding sleeve 34 follows and moves and drives second permanent magnet 44 to move, second permanent magnet 44 moves and drives two first permanent magnets 42 inside transparent tube 40 to follow close second permanent magnet 44 to move, because two are pulled by connecting rope 41, at this moment, two first permanent magnets 42 move and rotate, drive connecting rope 41 to move and rotate, connecting rope 41 at this moment is identical with the tilting state, tilt angle and tilted position of micro pile pipe 1 inside composite foundation, and the tilted moving position of micro pile pipe 1 needs to extend the moving distance of connecting rope 41 by multiple according to the length of micro pile pipe 1 and can be obtained, at the same time, by rotating swivel 45, swivel 45 rotates and drives vertical pin 46 to rotate, makes it possible to quickly see at what height micro pile pipe 1 tilts through vertical pin 46 and connecting rope 41, is convenient for later maintenance and maintenance.
