Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a device for replacing and bracing steel sheet piles in deep foundation pits. Background Technique

[0002] Replacing and bracing steel sheet piles in deep foundation pits means adopting certain technical measures to gradually replace the internal support structure that plays a temporary support role under specific conditions, so as to ensure that the project can continue safely and with high quality after the temporary support is removed. After retrieval, the patent with the Chinese patent publication number CN211446949U discloses a detachable replacement and bracing structure for deep foundation pits. Although this device can detachably support the basement exterior wall and the retaining pile through two support arms hinged on the chassis, facilitating the construction of backfill compaction operations, reducing the construction difficulty, and also saving construction costs, the length of this device cannot be adjusted during use, which leads to limitations on the distance to the retaining pile during use. When the distance between the retaining piles is relatively close or far, this device cannot adjust its length according to the distance of the retaining piles. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a device for replacing and bracing steel sheet piles in deep foundation pits, which solves the problem that the existing device in the background art cannot adjust the length of the device according to the distance of the steel sheet piles during use, resulting in limitations in use.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: A device for replacing and bracing steel sheet piles in deep foundation pits includes a device main body, an adjustment base, a threaded rod, a support plate, and a connecting rod. Two ear plates are welded on one surface of the device main body, and bolt holes are opened at both ends of the surface of the ear plates. An adjustment base plate is arranged on the other surface of the device main body. The surface of the adjustment base is in sliding contact with the surface of the device main body, and a threaded rod is arranged on one side of the adjustment base. One end of the threaded rod is rotatably connected to the adjustment base, and the other end of the threaded rod is welded to an adjustment disc. The outer parts of both ends of the threaded rod are threadedly connected to sliders. One end of the slider is rotatably connected to one end of the support plate, and the other end of the support plate is threadedly connected to one end of a connecting block. The inside of the connecting block is welded to one end of the connecting rod, and the other end of the connecting rod is welded to a first clamp. A second clamp is arranged on one side of the first clamp, and the first clamp and the second clamp are bolted to each other, and the first clamp and the second clamp are fixed outside the steel sheet pile body.

[0005] Preferably, the support plate is arranged in an inclined shape, and there are two support plates, and the two support plates are symmetrically distributed up and down. The two support plates can form a triangular structure, which is beneficial to improving the firmness of the support for the connecting rod.

[0006] Preferably, there are gaps between both sides of the adjustment base and both sides of the device body, and both sides of the device body are threadedly connected to the adjustment bolts. One end of each adjustment bolt is in close contact with the side surface of the adjustment base. By tightening the adjustment bolts, one end of each adjustment bolt can be made to press against both sides of the adjustment base, so that the adjustment base can be fixed to one side of the device body.

[0007] Preferably, threads are distributed on both ends of the threaded rod, and the thread directions at both ends of the threaded rod are opposite, which is beneficial to making the two sliders at both ends move in opposite directions while the threaded rod rotates.

[0008] Preferably, both ends of the sliding rods are welded to both sides of the bottom and both sides of the top of the device body. The outside of the sliding rods is in sliding fit with the inside of one end of the bottom and one end of the top of the adjustment base. The sliding rods are beneficial to restricting the movement of the adjustment base, so that the adjustment base can only move horizontally.

[0009] The utility model provides a device for replacing and bracing steel sheet piles in deep foundation pits. It has the following beneficial effects:

[0010] (1) For the device for replacing and bracing steel sheet piles in deep foundation pits, when the device is in use, the ear plates are fixed to one side wall of the steel sheet pile through bolts. By rotating the adjustment disc, the adjustment disc can drive the threaded rod to rotate. While the threaded rod rotates, it can drive the two external sliders to move synchronously, so that the two sliders can adjust the angle of the support plate, enabling the connecting rod to expand and contract, which is beneficial to adjusting the length of the device according to the distance between the steel sheet piles. Then, the steel sheet piles are supported by the first clamp and the second clamp. By removing the second clamp and rotating the adjustment disc in the reverse direction, the connecting rod can be contracted, so that the steel sheet piles can be replaced and braced.

[0011] (2) For the device for replacing and bracing steel sheet piles in deep foundation pits, after the device body is fixed, by rotating the adjustment bolts on both sides of the device body, the adjustment bolts can move through the threads on both sides of the device body, so that there is a gap between the adjustment base and one end of the adjustment bolt. The adjustment base can slide left and right through the sliding rods. While the adjustment base slides left and right, it can finely adjust the horizontal position of the first clamp and the second clamp to align them with the steel sheet pile body, which is beneficial to reducing the requirement for the installation accuracy of the device body.

[0012] Thus, the problem that the existing device cannot adjust the length of the device according to the distance between the steel sheet piles during use, resulting in limitations in use, is solved. BRIEF DESCRIPTION OF THE DRAWINGS

Two ear plates 2 are welded on one side surface of the device main body 1. Bolt holes are opened at both ends of the surface of the ear plate 2. An adjusting base is arranged on the other surface of the device main body 1. The surface of the adjusting base 3 is in sliding contact with the surface of the device main body 1. And a threaded rod 4 is arranged on one side of the adjusting base 3. One end of the threaded rod 4 is rotatably connected to the adjusting base 3. And the other end of the threaded rod 4 is welded to an adjusting disc 5. The outer parts of both ends of the threaded rod 4 are threadedly connected to sliders 6. One end of the slider 6 is rotatably connected to one end of the support plate 7. And the other end of the support plate 7 is threadedly connected to one end of a connecting block 8. The inside of the connecting block 8 is welded to one end of the connecting rod 9. And the other end of the connecting rod 9 is welded to a first clamp 10. A second clamp 11 is arranged on one side of the first clamp 10. And the first clamp 10 and the second clamp 11 are connected to each other by bolts. And the first clamp 10 and the second clamp 11 are fixed to the outside of the steel sheet pile body 12. The support plate 7 is arranged in an inclined shape. And there are two support plates 7 which are symmetrically distributed up and down. By rotating the adjusting disc 5, the adjusting disc 5 can drive the threaded rod 4 to rotate. While the threaded rod 4 rotates, it can drive the two external sliders 6 to move synchronously. Furthermore, the two sliders 6 can adjust the angle of the support plate 7, enabling the connecting rod 9 to expand and contract. Thus, it is beneficial to adjust the length of the device according to the distance between the steel sheet piles. Furthermore, the steel sheet piles are supported by the first clamp 10 and the second clamp 11.

[0022] Embodiment 2:

[0023] There are gaps between both sides of the adjusting base 3 and both sides of the device main body 1. And both sides of the device main body 1 are threadedly connected to adjusting bolts 13. One end of the adjusting bolt 13 is in close contact with the side surface of the adjusting base 3. Both ends of the bottom and both ends of the top of the device main body 1 are welded to both ends of a sliding rod 14. The outside of the sliding rod 14 is slidably matched with the inside of one end of the bottom and one end of the top of the adjusting base 3. After the device main body 1 is fixed, by rotating the adjusting bolts 13 on both sides of the device main body 1, the adjusting bolts 13 can move through the threads on both sides of the device main body 1. Thus, there is a gap between the adjusting base 3 and one end of the adjusting bolt 13, enabling the adjusting base 3 to slide left and right through the sliding rod 14. While the adjusting base 3 slides left and right, it can finely adjust the horizontal position of the first clamp 10 and the second clamp to align them with the steel sheet pile body 12. Thus, it is beneficial to reduce the requirement for the installation accuracy of the device main body 1.

[0024] Working principle: When in use, the device fixes the ear plate 2 to one side wall of the steel sheet pile through bolts. By rotating the adjustment disc 5, the adjustment disc 5 can drive the threaded rod 4 to rotate. While the threaded rod 4 rotates, it can drive two external sliders 6 to move synchronously, so that the two sliders 6 can adjust the angle of the support plate 7, enabling the connecting rod 9 to expand and contract. This is beneficial for adjusting the length of the device according to the distance between the steel sheet piles. Then, the steel sheet pile is supported by the first clamp 10 and the second clamp 11. By removing the second clamp 11 and rotating the adjustment disc 5 in the reverse direction, the connecting rod 9 can be contracted, allowing the steel sheet pile to be replaced for bracing. After the device body 1 is fixed, by rotating the adjustment bolts 13 on both sides of the device body 1, the adjustment bolts 13 can move through the threads on both sides of the device body 1. As a result, there is a gap between the adjustment base 3 and one end of the adjustment bolt 13, enabling the adjustment base 3 to slide left and right through the slide rod 14. When the adjustment base 3 slides left and right, it can finely adjust the horizontal position of the first clamp 10 and the other clamp to align with the steel sheet pile body 12, which is beneficial for reducing the requirements for the installation accuracy of the device body 1.
