[0024] See also Figure 1 and Figure 6The straightening mechanism 6 includes a base frame 61, one end of which is fixed with a second cylinder 62, and the other end of the base frame 61 is hinged with a straightening plate 64, and an inclined support frame 63 is arranged between the angles of the base frame 61 and the straightening plate 64.

[0025] See also Figure 7 , Figure 8 and Fig. 9 The inner side of the second guide wheel 5 is provided with an upper cone cavity 54, a lower cone cavity 55, and a cylindrical cavity 56 connecting the upper cone cavity 54 with the lower cone cavity 55. A flow channel 57 communicating with the lower cone cavity 55 is provided on a hub 51 on one side of the second guide wheel 5. The flow channels 57 on the two second guide wheels 5 are respectively located on different sides. The spacing between the two second guide wheels 5 is equal to the diameter of the hub 51. The punctuation mechanism 53 includes a hollow tube 531. The outer side of the hollow tube 531 is fixed with first cones respectively arranged in the upper cone cavity 54 and the lower cone cavity 55. The hollow tube 531 is provided with a spring 537, one end of the spring 537 abuts against the first cone plug 532, and the other end of the spring 537 abuts against the bottom wall of the upper cone cavity 54. The inner side of the hollow tube 531 is provided with a liquid storage cavity 534, and the bottom of the liquid storage cavity 534 is provided with a liquid outlet hole 536 leading to the cylindrical cavity 56. The top of the hollow tube 531 passes through the upper cone cavity 54 and extends to the wheel groove 52, and extends to the position of the wheel groove 52 to fill the liquid storage cavity 534. The top of the hollow tube 531 and the hole in the wheel groove 52 are matched with each other in a clearance, so as to facilitate the entry of air and help the discharge of the marking liquid in the inner cavity of the second guide wheel 5. In the process of slowly driving the two movable brackets 2 to move back and forth by the driving mechanism 3, the two second guide wheels 5 continuously roll on the second guide rail 13. When the hollow tube 531 rolls to contact the second guide rail 13, the hollow tube 531 can overcome the elastic force of the spring 537 and shrink downward under the squeezing of the second guide rail 13, so that the external air enters the inner cavity of the wheel hub 51 through the hole in the wheel groove 52, so that the marking liquid in the inner cavity of the wheel hub 51 can drip out through the flow channel 57. Since the flow channels 57 on the two second guide wheels 5 are respectively on different sides, the spacing between the two second guide wheels 5 is equal to the diameter of the wheel hub 51, so that two sets of marking points can be formed on the top surface of the earth wall below. Fig.11 The location of the small and medium circles, the midpoint of each group of marked points is the grouting point Fig.11 At the location of the middle and large circle, holes are drilled at the grouting points using a drilling device to facilitate the grouting equipment to perform grouting in the holes.

[0026] See also Fig.12 The outer end of the interlaced beam 8 is provided with a reinforcement structure 7 for further reinforcing the earth wall after straightening. The reinforcement structure 7 includes a wooden frame 71 connected to the interlaced beam 8 by mortise and tenon, and an anchor rod 72 anchored to the outer end of the interlaced beam 8. The outer end of the anchor rod 72 penetrates the earth wall and is fixed with a leech climber 73 that abuts against the outer wall surface of the earth wall. During the straightening construction, the interlaced beam 8 is fully utilized to connect and tie with the earth wall, so that the wooden structure of the interlaced beam 8 and the earth wall form a whole. In this way, the earth wall is no longer an independent structure, which effectively alleviates the wall deflection and improves the seismic resistance of the wall. For some cases where the wall thickness is relatively thin, the earth wall can be reinforced by using only the structure of the leech climber 73 to further improve the stability of the earth wall after straightening.

[0027] Based on the righting structure in the above embodiment, the present invention further provides a method for using the righting structure, comprising the following steps: Step 1: Strengthen the support, build the top frame 1 above the earth wall, and place the two straightening mechanisms 6 on both sides of the earth wall respectively, assemble and fix the mobile bracket 2 and the straightening mechanism 6, and drive the two mobile brackets 2 to drive the straightening mechanism 6 to adjust the use position according to the inclination direction of the two ends of the earth wall through the driving mechanism 3, and then fix the straightening mechanism 6 to the foundation, so that the two straightening mechanisms 6 support the two ends of the inclined earth wall; Step 2: Foundation treatment: dig the soil around the earth wall, recompact the foundation, and pour concrete on the foundation; Step three, pre-treatment of the earth wall straightening, chiseling holes corresponding to the interlaced beams 8 on the inner wall surface corresponding to the earth wall straightening, so as to facilitate the installation and fixation of the reinforcement structure 7.

[0028] Step 4: straightening and reinforcing the wall. The two straightening mechanisms 6 work simultaneously to gradually push the inclined earth wall on both sides until the wall is straightened to a vertical state. The wall and the interlaced beams 8 extending from the original building are fixed by the reinforcement structure 7, and the holes on the earth wall around the reinforcement structure 7 are filled and sealed. Step 5: Grouting marking. The mobile bracket 2 and the straightening mechanism 6 are unmounted so that the two straightening mechanisms 6 can still reinforce and support the earth wall. The two mobile brackets 2 are driven to move back and forth by the driving mechanism 3 again. Two sets of marking points are formed on the earth wall by the two second guide wheels 5 on the mobile bracket 2. The midpoint of each set of marking points is taken as the grouting point. The grouting is performed after drilling holes at the grouting points by the punching equipment. Step 6: dismantle the support, first dismantle the two mobile brackets 2 and the top frame 1, then unload the two straightening mechanisms 6, and remove the two straightening mechanisms 6 from the foundation; Step seven, wall repair, hang wire mesh on the earth wall, cover it with cement mortar, and then level it by plastering.

[0029] The working principle and use process of the present invention are as follows: when straightening a single-sided inclined earth wall, the two straightening mechanisms 6 can be moved to the inclined side of the earth wall, and the two straightening mechanisms 6 work together to straighten the single-sided inclined earth wall. Fig.10 The double-sided inclined earth wall shown in the figure is straightened, and the specific operation is as follows: the first cylinder 31 works to push the angle plate 34, and the angle plate 34 drives the rotating arm 32 to rotate around the rotating shaft 33, and then the waist-shaped groove of the rotating arm 32 limits the limit shafts 24 of the two movable brackets 2, and drives the two movable brackets 2 to move synchronously relative to each other, so that the two straightening mechanisms 6 can be moved to the inclined sides of the two ends of the earth wall, and then the base frame 61 is fixed to the two sides of the earth wall by bolts. The second hinge shaft 67 is pushed by the second cylinder 62, and the diagonal support frame 63 presses the straightening plate 64 downward, so that the straightening plate 64 gradually pushes the inclined wall until the wall changes from an inclined state to a vertical state; When the earth wall needs to be marked with grouting, the foot bolts of the side plate 25 are removed from the base frame 61, and the sealing plug 535 on the top of the hollow tube 531 is removed. The marking liquid is injected into the liquid storage chamber 534 and then the sealing plug 535 is filled. Finally, the sealing plug 535 at the bottom of the flow channel 57 is removed, and the two movable brackets 2 are slowly driven to move back and forth by the driving mechanism 3 again. During this process, the two second guide wheels 5 continue to roll on the second guide rail 13. When the hollow tube 531 rolls to the first When the two guide rails 13 are in contact, the hollow tube 531 can be squeezed by the second guide rail 13 to overcome the elastic force of the spring 537 and shrink downward, so that the external air enters the inner cavity of the hub 51 through the hole in the wheel groove 52, so that the marking liquid in the inner cavity of the hub 51 can drip out through the flow channel 57. Since the flow channels 57 on the two second guide wheels 5 are respectively on different sides, the distance between the two second guide wheels 5 is equal to the diameter of the hub 51, so that two sets of marking points can be formed on the top surface of the earth wall below. Fig.11 The location of the small and medium circles, the midpoint of each group of marked points is the grouting point Fig.11 At the location of the middle and large circle, holes are drilled at the grouting points using a drilling device to facilitate the grouting equipment to perform grouting in the holes.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

The soil wall repairing structure according to claim 8, characterized in that: The reinforcement structure (7) comprises a mortise and tenon connection (71) with the inserted beam (8), and an anchor rod (72) anchored to the outer end of the inserted beam (8), wherein the outer end of the anchor rod (72) penetrates the earth wall and is fixed with a leech (73) that contacts the outer wall surface of the earth wall.

10. A method for using a straightening structure, according to the straightening structure for repairing earth walls according to claim 1, characterized in that: The following steps are involved: Step 1: Strengthen the support, build the top frame (1) above the earth wall, and place the two straightening mechanisms (6) on both sides of the earth wall respectively, assemble and fix the movable bracket (2) and the straightening mechanism (6), and drive the two movable brackets (2) to drive the straightening mechanism (6) to adjust the use position according to the inclination direction of the two ends of the earth wall through the driving mechanism (3), and then fix the straightening mechanism (6) to the foundation, so that the two straightening mechanisms (6) support the two ends of the inclined earth wall; Step 2: Foundation treatment: dig the soil around the earth wall, recompact the foundation, and pour concrete on the foundation; Step 3: Pre-treatment of the earth wall straightening: holes corresponding to the interlaced beams (8) are chiseled on the inner wall surface corresponding to the earth wall straightening to facilitate the installation and fixation of the reinforcement structure (7); Step 4: straightening and reinforcing the wall. The two straightening mechanisms (6) work simultaneously to gradually push the inclined earth wall on both sides until the wall is straightened to a vertical state. The wall is fixed to the interlaced beams (8) extending from the original building through the reinforcement structure (7), and the holes on the earth wall around the reinforcement structure (7) are filled and sealed. Step 5: grouting marking. The movable bracket (2) and the straightening mechanism (6) are disassembled so that the two straightening mechanisms (6) can still reinforce and support the earth wall. The two movable brackets (2) are driven to move back and forth by the driving mechanism (3) again. Two second guide wheels (5) on the movable bracket (2) form two groups of marking points on the earth wall. The midpoint of each group of marking points is taken as the grouting point. The grouting is performed after drilling holes at the grouting points by the drilling equipment. Step 6: dismantle the support, first dismantle the two movable brackets (2) and the top frame (1), then uninstall the two righting mechanisms (6), and remove the two righting mechanisms (6) from the foundation; Step seven, wall repair, hang wire mesh on the earth wall, cover it with cement mortar, and then level it by plastering.
