Description

Technical Field

[0001] The invention relates to the technical field of earth retaining devices, in particular to an earth retaining device for original soil retention construction. Background Art

[0002] During the construction of high slope arched mortar-laid stone skeleton slope protection, the slope earth needs to be excavated into an arched trench according to the design requirements of the drawings. When digging the trench on the slope, the earth above the arched trench is lacking, and the supporting points below are prone to collapse, making it difficult to form the arch shape, affecting the construction. Therefore, retaining tools are needed to block and support the bottom of the earth.

[0003] In the prior art, the retaining tool is mainly composed of an arc-shaped retaining plate and a fixing rod for fixing the retaining plate. When using the retaining tool, the retaining plate and the fixing rod are knocked into the soil at a designated position in the trench. When excavating the trench, the retaining plate can support the earth with the help of the fixing rod to prevent the earth from sliding.

[0004] During the trench excavation process, the soil under the retaining wall is dug away, so the fixing rods will gradually be exposed, causing the fixing rods to gradually lose the support of the soil. At this time, the fixing rods are easily tilted due to the squeezing of the soil, thereby affecting the supporting function of the fixing rods and reducing the stability of the fixing rods when supporting the retaining wall.

[0022] like Figure 2-9As shown, the lower end of the limiting tube 401 is rotatably connected with the soil-breaking block 406, and the soil-breaking block 406 is of a semi-conical structure. The circular plate 402 is internally threadedly connected with a screw rod 403, and the screw rod 403 is located in the limiting tube 401. The upper end of the screw rod 403 is fixedly connected with the extension plate 404, and the lower end of the screw rod 403 is rotatably connected with a connecting block 405. The arc surface of the soil-breaking block 406 is fixedly connected with a drawstring 407, and one end of the drawstring 407 is fixedly connected with the connecting block 405. A clearance groove 408 is provided on the arc surface of the soil-breaking block 406, and the drawstring 407 is slidably connected with the clearance groove 408. The lower surface of the circular plate 402 is fixedly connected with an insert plate 413; the screw rod 403 slides through the extension plate 404 to drive the circular plate 402 to slide, and the sliding of the circular plate 402 causes the limiting tube 401 to pass through the casing 2 and insert into the soil. The circular plate 402 slides to insert the plug 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 rod 403 to rotate. At this time, the plug plate 413 can prevent the circular plate 402 from rotating, thereby preventing the limiting tube 401 from rotating with the screw rod 403. The screw rod 403 moves upward through the thread. The rotation of the screw rod 403 drives the connecting block 405 to move. The connecting block 405 moves to pull the drawstring 407. When the connecting block 405 slides out of the slot 409, the drawstring 407 is tightened. Therefore, the connecting block 405 continues to move and drives the soil-breaking block 406 to rotate through the drawstring 407. The soil-breaking block 406 is embedded in the soil around the limiting tube 401, thereby strengthening the supporting effect of the limiting tube 401 on the sleeve 2 and improving the stability of the retaining plate 1 during operation.

[0023] like Figure 2 and Fig.10 As shown, a slot 409 is provided on the upper surface of the soil-breaking block 406, and the lower end of the connecting block 405 is embedded in the slot 409. The connecting block 405 can prevent the two soil-breaking blocks 406 from rotating. The two soil-breaking blocks 406 will form a cone structure, which is convenient for the limiting tube 401 to slide downward; two sliding grooves 411 are provided 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, and the slide groove 411 limits the sliding path of the connecting block 405 to prevent the connecting block 405 from rotating with the screw rod 403; the limiting tube 401 is rotatably connected with the cylindrical block 412 relative to the position of the pull belt 407, and the cylindrical block 412 is slidably connected with the pull belt 407. In the process of the pull belt 407 pulling the earth-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 of the limit tube 401 on the pull belt 407.

[0024] like Figure 3 and Fig.11As shown, the upper surface of the mounting plate 51 is fixedly connected to the fixing bar 52, the fixing bar 52 is slidably connected to the adjusting rod 53, the knocking block 54 is slidably sleeved on the fixing bar 52 and the adjusting rod 53, the lower surface of the mounting plate 51 is fixedly connected with a positioning plate 55, and 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, and the positioning plate 55 is slidably connected to the extension plate 404, the mounting plate 51 is moved, the mounting plate 51 drives the positioning plate 55 to move, and 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, and then the knocking block 54 is slidably sleeved on the fixing bar 52 and the adjusting rod 53, and the knocking block 54 is slid downward, and the knocking block 54 hits the mounting plate 51 to make the extension plate 404 slide downward, because the adjusting rod 53 can Sliding along the inner wall of the fixing strip 52, the adjusting rod 53 can extend the sliding distance of the knocking block 54, so that the knocking block 54 is lifted to a higher distance and then slides downward to hit the mounting plate 51, and the adjusting rod 53 and the fixing strip 52 guide the sliding path of the knocking block 54; a transmission plate 57 is fixedly connected to the adjusting rod 53, and an offset groove 58 is provided on the knocking block 54, and the offset groove 58 is adapted to the transmission plate 57. When the offset groove 58 is aligned with the transmission plate 57, the knocking block 54 is removed from the surface of the adjusting rod 53 and the fixing strip 52; the vertical section of the positioning plate 55 is in an "L" shape, and an inclined surface is provided at the lower end of the positioning plate 55. The inclined surface provided 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 section of the positioning plate 55 is in an "L" shape, the positioning plate 55 can drive the extension plate 404 to slide when it slides upward.

[0025] like Fig. 9 and Fig.10 As shown, a bent plate 62 is slidably connected in the rectangular groove 61, and the bent plate 62 is fixedly connected to the support plate 63. A plurality of 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, and the retaining plate 1 is knocked downward, and the retaining plate 1 drives the serrated plate 3 to be inserted into the soil. At this time, the retaining plate 1 and the serrated plate 3 support the original soil above the arched groove pit through the limiting tube 401, and the bent plate 62 is inserted into the rectangular groove 61. The sliding of the bent plate 62 drives the supporting plate 63 to slide. When the supporting plate 63 is against the soil surface, the supporting plate 63 supports the bent plate 62, thereby supporting the retaining plate 1; the retaining plate 1 is fixedly connected with a triangular block 66 relative to the position of the bolt 64, and the bolt 64 is against the inclined surface of the triangular block 66. The rotating bolt 64 is against the inclined surface of the triangular block 66, and the triangular block 66 prevents the bolt 64 from sliding upward, thereby improving the fixing effect of the bolt 64 on the bent plate 62.

[0026] Working principle: before excavating the arched trench, place the retaining plate 1 at the designated position, then insert the limiting tube 401 into the casing 2, and then move the mounting plate 51, which drives the positioning plate 55 to move, so that the positioning plate 55 slides 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. When the positioning plate 55 slides out from the top to the bottom along the positioning groove 56, the mounting plate 51 is rotated to dislocate the positioning plate 55 and the positioning groove 56, and then the knocking block 54 is moved to align the dislocation groove 58 with the transmission plate 57. Then, the knocking block 54 is slidably sleeved on the fixing strip 52 and the adjusting rod 53, and then the knocking block 54 is slid downward. After the knocking block 54 hits the mounting plate 51, the extension plate 404 slides downward. The sliding of the extension plate 404 drives the sliding of the circular plate 402. The sliding of the circular plate 402 causes the limiting tube 401 to pass through the sleeve 2 and insert into the soil. In this process, since the connecting block 405 is embedded in the card 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 limiting tube 401 to slide downward. Due to the adjusting rod 53 The adjusting rod 53 extends the sliding distance of the knocking block 54 so that the knocking block 54 is lifted to a higher distance and then slides downward to hit the mounting plate 51. The adjusting rod 53 and the fixing bar 52 guide the sliding path of the knocking block 54. The circular plate 402 slides to insert the plug 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 rod 403 to rotate. At this time, the plug plate 413 prevents the circular plate 402 from rotating, preventing the limiting tube 401 from rotating along with the screw rod 403. 03 moves upward, the screw rod 403 drives the connecting block 405 to move, and the connecting block 405 moves to pull the drawstring 407. When the connecting block 405 slides out from the inner wall of the slot 409, the drawstring 407 will be tightened, so the connecting block 405 continues to move to make the drawstring 407 drive the soil-breaking block 406 to rotate, and the soil-breaking block 406 will be embedded in the soil around the limiting pipe 401, thereby increasing the contact area between the limiting pipe 401 and the soil, increasing the anti-collapse ability of the limiting pipe 401, improving the supporting effect of the limiting pipe 401 on the casing 2, and improving the stability of the retaining plate 1 when working;In 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 of the limiting tube 401 on the pull belt 407, and the sliding of the connecting block 405 drives the slider 410 to slide along the sliding groove 411, and the sliding groove 411 reaches the limit sliding path of the slider 410, thereby limiting the sliding path of the connecting block 405, preventing the connecting block 405 from rotating with the screw rod 403 to cause the two pull belts 407 to entangle with each other, and then knocking down the retaining plate 1, the retaining plate 1 drives the sawtooth plate 3 to be inserted into the soil at the same time, and the retaining plate 1 and the sawtooth plate 3 are inserted into the soil at the same time. The tooth plate 3 supports the original soil above the arched groove pit through the limiting tube 401, and the bending plate 62 is inserted into the rectangular groove 61. The sliding of the bending plate 62 drives the supporting plate 63 to slide. When the supporting plate 63 is against the soil surface, the bolt 64 is rotated, and the bolt 64 moves against the inclined surface of the triangular block 66. The triangular block 66 prevents the bolt 64 from moving upward, thereby improving the fixing effect of the bolt 64 on the bending plate 62. The anti-slip strip 65 increases the friction between the supporting plate 63 and the soil. The supporting plate 63 supports the bending plate 62, thereby supporting the retaining plate 1, and further improving the stability of the retaining plate 1 supporting the original soil. ;

[0027] When removing the retaining plate 1, first rotate the extension plate 404 in the opposite direction, the connecting block 405 moves downward with the screw rod 403, the pull belt 407 will be in a relaxed state, and then slide the knocking block 54 upward. When the knocking block 54 contacts the transmission plate 57, the transmission plate 57 drives the adjustment rod 53 to slide upward until the adjustment rod 53 stops sliding. At this time, the adjustment rod 53 drives the fixing bar 52 to slide upward, the mounting plate 51 slides through the fixing bar 52 and drives the positioning plate 55 to slide, the positioning plate 55 drives the extension plate 404 to slide, and the screw rod 403 passes through the extension plate 4 04 slides and drives the limiting tube 401 to slide upward, then slides the knocking block 54 back and forth in the vertical direction to pull the limiting tube 401 out of the soil, and then rotates the bolt 64 in the opposite direction to disengage the bolt 64 from the triangular block 66, so that the support plate 63 loses its support for the retaining plate 1, and then the retaining plate 1 is removed from under the original soil; when the positioning plate 55 is aligned with the positioning groove 56, the mounting plate 51 is removed from the extension plate 404; when the dislocation groove 58 is aligned with the transmission plate 57, the knocking block 54 is removed from the adjusting rod 53 and the fixing bar 52 for easy turnover.
