Description

Technical Field

[0001] This invention relates to the field of retaining device technology, specifically to a retaining device for original soil fixation construction. Background Technology

[0002] During the construction of arched masonry rubble masonry frame slope protection on high slopes, according to the design requirements, the slope soil needs to be excavated into an arched trench. When excavating the trench on the slope, the soil above the arched trench is insufficient, and the support points below are prone to collapse, making it difficult to form the arch shape and affecting construction. Therefore, it is necessary to use retaining tools to block and support the soil below.

[0003] In the existing technology, retaining tools mainly consist of an arc-shaped retaining plate and a fixing rod for fixing the retaining plate. When using retaining tools, the retaining plate and fixing rod are driven into the soil at a designated position in the trench. When excavating the trench, the retaining plate can support the soil with the help of the fixing rod to prevent the soil from sliding down.

[0004] During the excavation of the trench, as the soil under the retaining plate is removed, the fixing rod will gradually be exposed, causing the fixing rod to gradually lose the support of the soil. At this time, the fixing rod is prone to tilting due to the compression of the soil, thus affecting the supporting role of the fixing rod and reducing the stability of the fixing rod when supporting the retaining plate.

[0005] Therefore, we propose a soil retaining device for original soil stabilization construction. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-11 This invention provides a technical solution: a retaining device for soil stabilization construction, comprising a retaining plate 1 and a sleeve 2. The sleeve 2 is fixedly connected to the retaining plate 1. A serrated plate 3 is welded to the lower surface of the retaining plate 1. A limiting structure 4 for improving the stability of the retaining plate 1 is provided inside the sleeve 2. The limiting structure 4 includes a limiting tube 401 slidably connected to the inner wall of the sleeve 2, and two soil-breaking blocks 406 for facilitating soil breaking by the limiting tube 401. A circular plate 402 is fixedly connected to the upper end of the limiting tube 401. An extension plate 404 is slidably connected to the upper surface of the circular plate 402. The upper surface of the extension plate 404 is provided with a useful... To facilitate the insertion of the limiting tube 401 into the soil, a striking structure 5 is provided. The striking structure 5 includes a mounting plate 51 slidably connected to the upper surface of the extension plate 404, a striking block 54 for driving the limiting tube 401 downward by striking the mounting plate 51, a fixing strip 52 for limiting the sliding path of the striking block 54, and an adjusting rod 53. A support structure 6 is provided inside the retaining plate 1 for supporting the retaining plate 1. The support structure 6 includes a rectangular groove 61 opened on the upper surface of the retaining plate 1, a support plate 63 for supporting the retaining plate 1, and bolts 64 for fixing the support plate 63.

[0038] like Figure 2-9As shown, the lower end of the limiting tube 401 is rotatably connected to the soil-breaking block 406. The soil-breaking block 406 has a semi-conical structure. A screw rod 403 is internally threaded onto the circular plate 402. The screw rod 403 is located inside the limiting tube 401. The upper end of the screw rod 403 is fixedly connected to the extension plate 404. The lower end of the screw rod 403 is rotatably connected to the connecting block 405. A pull strap 407 is fixedly connected to the arc surface of the soil-breaking block 406. One end of the pull strap 407 is fixedly connected to the connecting block 405. A clearance groove 408 is provided on the arc surface of the soil-breaking block 406. The pull strap 407 is slidably connected to the clearance groove 408. An insert plate 413 is fixedly connected to the lower surface of the circular plate 402. The screw rod 403 slides through the extension plate 404, causing the circular plate 402 to slide. The sliding of the circular plate 402 causes the limiting tube 401 to pass through the sleeve 2 and insert into the soil. The circular plate 402 slides to insert the insertion plate 413 into the soil. When the limiting tube 401 is inserted to a certain depth, the extension plate 404 is rotated. The rotation of the extension plate 404 drives the screw 403 to rotate. At this time, the insertion plate 413 can prevent the circular plate 402 from rotating, thereby preventing the limiting tube 401 from rotating with the screw 403. The screw 403 moves upward through the thread. The rotation of the screw 403 drives the connecting block 405 to move. The movement of the connecting block 405 pulls the strap 407. When the connecting block 405 slides out of the slot 409, the strap 407 is tightened. Therefore, the connecting block 405 continues to move and drives the soil-breaking block 406 to rotate through the strap 407. The soil-breaking block 406 is embedded in the soil around the limiting tube 401, which strengthens the support effect of the limiting tube 401 on the sleeve 2 and improves the stability of the retaining plate 1 when it is working.

[0039] like Figure 2 and Figure 10 As shown, a groove 409 is formed on the upper surface of the soil-breaking block 406, and the lower end of the connecting block 405 is embedded in the groove 409. The connecting block 405 can prevent the two soil-breaking blocks 406 from rotating, and the two soil-breaking blocks 406 will form a conical structure, which facilitates the downward sliding of the limiting tube 401. Two sliding grooves 411 are formed on the inner wall of the limiting tube 401, and a slider 410 is slidably connected in the sliding groove 411. The slider 410 is fixedly connected to the connecting block 405, and the sliding of the connecting block 405 drives the slider 410 along the sliding groove. 411 slides, the groove 411 restricts the sliding path of the connecting block 405 to prevent the connecting block 405 from rotating with the lead screw 403; the limiting tube 401 is rotatably connected to the position of the pull belt 407 with a cylindrical block 412, the cylindrical block 412 is slidably connected to the pull belt 407, and during the process of the pull belt 407 pulling the soil-breaking block 406 to rotate, the cylindrical block 412 can reduce the friction between the pull belt 407 and the limiting tube 401, thereby reducing the wear caused by the limiting tube 401 to the pull belt 407.

[0040] like Figure 3 and Figure 11As shown, the upper surface of the mounting plate 51 is fixedly connected to the fixing strip 52, and the fixing strip 52 is slidably connected to the adjusting rod 53. The striking block 54 is slidably sleeved on the fixing strip 52 and the adjusting rod 53. A positioning plate 55 is fixedly connected to the lower surface of the mounting plate 51. A positioning groove 56 is provided on the arc surface of the extension plate 404. The positioning groove 56 is adapted to the positioning plate 55. The positioning plate 55 is slidably connected to the extension plate 404. When the mounting plate 51 is moved, the mounting plate 51 drives the positioning plate 55 to move. The positioning plate 55 slides along the positioning groove 56. When the positioning plate 55 slides out of the positioning groove 56, the mounting plate 51 is rotated to make the positioning plate 55 misaligned with the positioning groove 56. Then, the striking block 54 is slidably sleeved on the fixing strip 52 and the adjusting rod 53. The striking block 54 slides downward. After the striking block 54 hits the mounting plate 51, the extension plate 404 slides downward. Because the adjusting rod 53 can... The adjusting rod 53 slides along the inner wall of the fixing strip 52, thus extending the sliding distance of the striking block 54, allowing the striking block 54 to be raised to a higher distance before sliding down to strike the mounting plate 51. The adjusting rod 53 and the fixing strip 52 guide the sliding path of the striking block 54. A transmission plate 57 is fixedly connected to the adjusting rod 53, and a misalignment groove 58 is provided on the striking block 54. The misalignment groove 58 is adapted to the transmission plate 57. When the misalignment groove 58 is aligned with the transmission plate 57, the striking block 54 can be removed from the surface of the adjusting rod 53 and the fixing strip 52. The vertical cross-section of the positioning plate 55 is "L"-shaped, and the lower end of the positioning plate 55 is provided with an inclined surface. The inclined surface on the lower surface of the positioning plate 55 facilitates the alignment of the positioning plate 55 and the positioning groove 56. Since the vertical cross-section of the positioning plate 55 is "L"-shaped, the extension plate 404 can slide when the positioning plate 55 slides upward.

[0041] like Figure 9 and Figure 10 As shown, a bent plate 62 is slidably connected inside the rectangular groove 61. The bent plate 62 is fixedly connected to the support plate 63. Multiple anti-slip strips 65 are fixedly connected to the lower surface of the support plate 63. The bolt 64 is threadedly connected to the bent plate 62. When the retaining plate 1 is struck downwards, the retaining plate 1 drives the serrated plate 3 to insert into the soil. At this time, the retaining plate 1 and the serrated plate 3 support the original soil above the arched groove through the limiting tube 401. The bent plate 62 is inserted into the rectangular groove 61. The bent plate 62 slides, causing the support plate 63 to slide. When the support plate 63 abuts against the soil surface, the support plate 63 supports the bent plate 62, thereby supporting the retaining plate 1. A triangular block 66 is fixedly connected to the retaining plate 1 relative to the position of the bolt 64. The bolt 64 abuts against the inclined surface of the triangular block 66. Rotating the bolt 64 abuts against the inclined surface of the triangular block 66. The triangular block 66 prevents the bolt 64 from sliding upwards, thereby improving the fixing effect of the bolt 64 on the bent plate 62.

[0042] Working principle: Before excavating the arched trench, the retaining plate 1 is placed in the designated position. Then, the limiting tube 401 is inserted into the sleeve 2. Next, the mounting plate 51 is moved, which drives the positioning plate 55 to move, allowing the positioning plate 55 to slide along the positioning groove 56. During this process, the inclined surface on the lower surface of the positioning plate 55 facilitates the alignment of the positioning plate 55 and the positioning groove 56. After the positioning plate 55 slides out from top to bottom along the positioning groove 56, the mounting plate 51 is rotated to misalign the positioning plate 55 with the positioning groove 56. Then, the striking block 54 is moved to align the misalignment groove 58 with the transmission plate 57. Next, the striking block 54 is slidably fitted onto the fixing strip 52 and the adjusting rod 53, and then the striking block 54 is slid downwards. After the striking block 54 hits the mounting plate 51, the extension plate 404 slides downwards. The sliding of the extension plate 404 drives the circular plate 402 to slide. The sliding of the circular plate 402 causes the limiting tube 401 to pass through the sleeve 2 and insert into the soil. During this process, because the connecting block 405 is embedded in the slot 409, the connecting block 405 prevents the two soil-breaking blocks 406 from rotating. The two soil-breaking blocks 406 form a conical structure to facilitate the downward sliding of the limiting tube 401. Because the adjusting rod 53... Sliding along the fixing bar 52, the adjusting rod 53 extends the sliding distance of the striking block 54, causing the striking block 54 to be raised to a higher distance before sliding down to strike the mounting plate 51. The adjusting rod 53 and the fixing bar 52 guide the sliding path of the striking block 54. The circular plate 402 slides, causing the insert plate 413 to insert into the soil. When the limiting tube 401 is inserted to a certain depth, the extension plate 404 rotates. The rotation of the extension plate 404 drives the screw 403 to rotate. At this time, the insert plate 413 prevents the circular plate 402 from rotating, preventing the limiting tube 401 from rotating with the screw 403. 03 moves upward, the screw 403 drives the connecting block 405 to move, the connecting block 405 moves and pulls the strap 407. When the connecting block 405 slides out from the inner wall of the slot 409, the strap 407 will be tightened. Therefore, the connecting block 405 continues to move, causing the strap 407 to drive the soil-breaking block 406 to rotate. The soil-breaking block 406 will embed into the soil around the limiting tube 401, thereby increasing the contact area between the limiting tube 401 and the soil, increasing the anti-falling ability of the limiting tube 401, improving the supporting effect of the limiting tube 401 on the sleeve 2, and improving the stability of the retaining plate 1 when it is working.During the process of the pull belt 407 pulling the soil-breaking block 406 to rotate, the cylindrical block 412 can reduce the friction between the pull belt 407 and the limiting tube 401, thereby reducing the wear caused by the limiting tube 401 on the pull belt 407. The connecting block 405 slides, causing the slider 410 to slide along the slide groove 411. The slide groove 411 restricts the sliding path of the slider 410, thereby restricting the sliding path of the connecting block 405 and preventing the connecting block 405 from rotating with the screw 403 and causing the two pull belts 407 to become entangled. Then, the retaining plate 1 is struck downwards, and the retaining plate 1 drives the saw toothed plate 3 to insert into the soil at the same time. At this time, the retaining plate 1 and the saw toothed plate 3 are inserted into the soil. The toothed plate 3 supports the original soil above the arched trench via the limiting tube 401. The bent plate 62 is inserted into the rectangular groove 61. The sliding of the bent plate 62 causes the support plate 63 to slide. When the support plate 63 abuts against the soil surface, the bolt 64 is rotated. The bolt 64 moves and abuts against the inclined surface of the triangular block 66. The triangular block 66 prevents the bolt 64 from moving upwards, thus improving the fixing effect of the bolt 64 on the bent plate 62. The anti-slip strip 65 increases the friction between the support plate 63 and the soil. The support plate 63 supports the bent plate 62, thereby supporting the retaining plate 1 and further improving the stability of the retaining plate 1 in supporting the original soil.

[0043] When removing retaining plate 1, first rotate the extension plate 404 in the opposite direction. The connecting block 405 moves downward with the screw 403, and the pull strap 407 will be in a slack state. Then slide the striking block 54 upward. When the striking block 54 contacts the transmission plate 57, the transmission plate 57 drives the adjusting rod 53 to slide upward until the adjusting rod 53 stops sliding. At this time, the adjusting rod 53 drives the fixing strip 52 to slide upward. The mounting plate 51 slides through the fixing strip 52 and drives the positioning plate 55 to slide. The positioning plate 55 drives the extension plate 404 to slide. The screw 403 passes through the extension plate 404. 04. Slide and drive the limiting tube 401 to slide upward. Then, slide the striking block 54 back and forth in the vertical direction to pull the limiting tube 401 out of the soil. Then, rotate the bolt 64 in the opposite direction to disengage the bolt 64 from the triangular block 66. The support plate 63 loses its support for the retaining plate 1. Then, remove the retaining plate 1 from under the original soil. When the positioning plate 55 is aligned with the positioning groove 56, remove the mounting plate 51 from the extension plate 404. When the misalignment groove 58 is aligned with the transmission plate 57, remove the striking block 54 from the adjusting rod 53 and the fixing strip 52 for easy turnover.
