[0001] This utility model relates to the field of hydraulic engineering technology, and in particular to a fixing device for improving the accuracy of ecological sheet pile driving. Background Technology

[0002] Current ecological sheet pile construction mainly relies on surveying and setting out for positioning, with manual assistance for the positioning of ecological sheet piles. This requires repeated surveying and positioning during construction, resulting in low work efficiency and an inability to effectively guarantee the accuracy of continuous installation of ecological sheet piles in complex geological environments. Utility Model Content

[0003] The purpose of this utility model is to solve the problem of low installation efficiency caused by the need for manual positioning and measurement for each ecological pile driven in the existing technology due to the high precision requirements of retaining wall construction. Therefore, a fixing device for improving the installation accuracy of ecological sheet piles is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fixing device for improving the driving accuracy of ecological sheet piles includes a support plate, a fixing grid in the middle of the support plate that fits tightly with the ecological sheet pile, and lifting lugs for lifting. The support plate is also provided with height-adjustable support foot assemblies for adjusting the horizontal position of the support plate.

[0005] In some embodiments, the size of the fixing grid is matched with the size of the ecological sheet pile for precise installation of the ecological sheet pile.

[0006] In some embodiments, the support plate is in the shape of a rectangular frame, and the support plate includes side plates and partitions, with the partitions being equally spaced inside the side plates.

[0007] In some embodiments, the outer side of the support plate is welded and fixed by four side plates, and a plurality of partitions perpendicular to the long side plates are provided on the inner side of the side plates to form multiple fixing grids.

[0008] In some embodiments, the side plates and partitions are both H-beams, and the H-beams of the side plates and partitions are of the same type.

[0009] In some embodiments, the support foot assembly is disposed at the four corners of the support plate to support the four corners of the support plate.

[0010] In some embodiments, the support leg assembly includes a fixed base, a lifting leg, and a first screw. The fixed base has a vertically penetrating lifting groove in the middle, and the lifting groove has a first threaded hole that extends outward and is adapted to the first screw in the middle. The lifting leg has a through hole. The bottom of the lifting leg is provided with a base.

[0011] In some embodiments, the end of the first screw is provided with a nut, and a nut groove is provided on the fixing seat at a position corresponding to the first threaded hole.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1 Reference Figures 1 to 5 A fixing device for improving the driving accuracy of ecological sheet piles includes a support plate 1, a fixing grid 4 in the middle of the support plate 1 that fits tightly with the ecological sheet pile, and a lifting lug 5 on the support plate 1 for lifting.

[0035] The dimensions of the fixed grid 4 are matched with the dimensions of the ecological sheet piles, which is used for the precise installation of the ecological sheet piles.

[0036] The support plate 1 has a rectangular frame shape. The support plate 1 includes side plates 2 and partitions 3. The partitions 3 are evenly spaced inside the side plates 2. Multiple ecological sheet piles are placed in multiple fixed grids 4 in sequence.

[0037] The outer side of the support plate 1 is welded and fixed by four side plates 2, and several partitions 3 perpendicular to the long side plates 2 are provided on the inner side of the side plates 2, forming multiple fixed grids 4.

[0038] Both side plate 2 and partition plate 3 are H-beams, and the H-beams of side plate 2 and partition plate 3 are of the same type.

[0039] In use, the construction location of the ecological sheet piles is first determined through precise on-site measurement and layout. Using lifting equipment, the support plate 1 is hoisted to the designated position via lifting lugs 5. Manual adjustments are then made to ensure the device is in place. After adjustment, a second measurement is conducted to verify the position and orientation of the ecological sheet piles. Once confirmed, the driving of the ecological sheet piles begins. The ecological sheet piles are again placed into the fixing grid 4 using lifting equipment, and then driven vertically into the soil by a pile driver under the constraint of the fixing grid 4, until the preset depth is reached.

[0040] After the eco-friendly sheet piles are installed, the device is moved to the next construction site using lifting equipment. This process is repeated to systematically advance the subsequent eco-friendly sheet pile construction.

[0041] Depending on the usage requirements, the lifting lug 5 can be detachably connected to the side plate 2. Depending on the usage requirements, the lifting lug 5 can be fixedly installed on the partition plate 3 to improve the stability of the lifting equipment when lifting the support plate 1.

[0042] Example 2 Please refer to Figures 1 to 9 In practical use, to further ensure the verticality and accuracy of the ecological sheet pile installation, the following improvements are made: A support foot assembly 6 is provided on the support plate 1. The height of the support foot assembly 6 is adjustable, which is used to adjust the horizontality of the support plate 1. By adjusting the overall height of the support plate 1, the verticality and accuracy of the ecological sheet pile installation are ensured. The support foot assembly 6 is located at the four corners of the support plate 1, providing support for the four corners of the support plate 1.

[0043] As one embodiment of the support leg assembly 6, the support leg assembly 6 includes a fixed base 601, a lifting leg 602 and a first screw 603. The fixed base 601 has a vertically penetrating lifting groove 6011 in the middle, and a first threaded hole 6012 that extends outward and is adapted to the first screw 603 in the middle of the lifting groove 6011. The lifting leg 602 has a through hole 6021.

[0044] The end of the first screw 603 is provided with a nut 6031. A nut groove 6013 is provided on the fixing base 601 at a position corresponding to the first threaded hole 6012. The diameter of the nut groove 6013 is equal to the diameter of the nut 6031, which is used to limit and support the nut 6031 after the first screw 603 is installed. The bottom of the lifting leg 602 is provided with a base 604.

[0045] In this embodiment, before the ecological sheet pile is placed into the fixing grid 4, the distance between the bottom of the lifting leg 602 and the support plate 1 can be adjusted in advance through the lifting groove 6011. After the four lifting legs 602 are adjusted, the first screw 603 is fixed between the fixing base 601 and the lifting leg 602 through the through hole 6021 and the first threaded hole 6012. Then, the base 604 at the bottom of the lifting leg 602 is limited to keep the position of the base 604. At this time, the overall horizontal position of the support plate 1 is close to the middle section of the ecological sheet pile. When the ecological sheet pile is driven into the ground, the fixing grid 4 located in the middle section of the ecological sheet pile applies a more stable corrective force to the ecological sheet pile. When the ecological sheet pile is driven downward, the entire ecological sheet pile is stable and straight from top to bottom, thereby improving the verticality.

[0046] As another aspect of this embodiment, in actual use, since the bottom surface of the foundation pit at the construction site is often uneven, one side is higher than the other when the support plate 1 is placed. At this time, the support plate 1 and the fixing grid 4 cannot be kept parallel to the ground, so the ecological sheet pile cannot be driven straight into the soil.

[0047] In response to this situation where one side is higher than the other, the lifting legs 602 at both ends of the support plate 1 are adjusted in height. Targeted leveling is achieved by adjusting the lifting legs 602 individually. For example, if the left side of the support plate 1 is higher than the right, the right lifting leg 602 is moved downwards along the lifting groove 6011 and fixed by the threaded engagement of the first screw 603 with the through hole 6021 and the first threaded hole 6012. The right lifting leg 602 is then extended until the entire support plate 1 is parallel to the ground surface. At this point, the fixing grid 4 of the support plate 1 provides a vertical channel downwards for the ecological sheet piles, allowing them to be driven vertically into the ground along the fixing grid 4.

[0048] Additionally, the base 604 can be used to connect to the ground to prevent the support leg assembly 6 from sliding or sinking due to vibration. Optionally, the base 604 can be fixed to the ground using anchor bolts or expansion bolts to improve the stability of the support leg assembly 6 in supporting the support plate 1. The method of fixing the base 604 to the ground is a mature technology in the field, so the connection between the base 604 and the ground will not be described in detail. When the support plate 1 is moved, the base 604 is first detached from the ground.

[0049] Example 3 This embodiment is a further improvement on the above embodiment. Please continue to refer to it. Figure 10 and Figure 11 A side compensation plate 201 is fixedly connected to the inner side of the side plate 2, and a partition compensation plate 301 is fixedly connected to the inner side of the partition plate 3. The inner side of the side compensation plate 201 is flush with the inner side of the side plate 2, and one side of the partition compensation plate 301 is flush with one side of the partition plate 3. The side compensation plate 201 of the side plate 2 is fixedly welded.

[0050] In use, by adding the side compensation plate 201 and the partition compensation plate 301, the spot welding at the two ends of the side plate 2 and the partition compensation plate 301 is changed to the line welding between the partition plate 3 and the partition compensation plate 301 and the side plate 2 and the side compensation plate 201, thereby further improving the stability of the structure.

[0051] In addition, the side compensation plate 201 and the partition compensation plate 301 can fill the empty slots of the side plate 2 and the partition plate 3, which not only helps to prevent the deformation of the main structure, but also makes the inner surface of the fixing grid 4 all on the same precision plane, providing a stable and vertically downward guiding channel for the ecological sheet pile.

[0052] Example 4 Please continue reading. Figure 12 and Figure 13 To improve the applicability of the fixing device, the side plate 2 and the partition plate 3 are set separately, and the positions of the side plate 2 and the partition plate 3 are fixed by the fixing support assembly 7.

[0053] As one embodiment of the fixed support assembly 7, the fixed support assembly 7 includes a mating groove 701 formed on the side of the partition 3 and the partition compensation plate 301, a slide 702 formed on the side of the side plate 2, and a snap-fit ​​plate 703. The end of the snap-fit ​​plate 703 is provided with a snap groove 704 that corresponds to and cooperates with the edge of the side plate 2. The snap-fit ​​plate 703 is provided with a fixing part that corresponds to and cooperates with the mating groove 701. The fixing part includes a second threaded hole 705 and a second screw 706 formed on the snap-fit ​​plate 703. One end of the second screw 706 is provided with a mating block 707 that corresponds to and cooperates with the mating groove 701. The diameter of the mating block 707 is equal to the diameter of the mating groove 701.

[0054] In the above scheme, the partition 3 does not need to be welded to the side plate 2, but a docking groove 701 can be opened on the side of the partition 3 and the partition compensation plate 301 to form a fixing grid 4 for the installation of ecological sheet piles; the partition 3 can move horizontally inside the side plate 2 to adjust the size of the fixing grid 4 to adapt to different specifications of ecological sheet piles. Specifically, in use, the partition plate 3 is placed inside the side plate 2. According to the specifications of the ecological sheet pile, the position of the partition plate 3 is measured and temporarily positioned to correspond to the position of the docking groove 701 and the slide 702. Then, the snap-fit ​​plate 703 is snapped onto the side plate 2 from the outside. The position of the snap-fit ​​plate 703 can be further adjusted by the sliding fit between the snap-fit ​​groove 704 and the edge of the side plate 2, so that the docking block 707 is directly aligned with the docking groove 701. Then, with the threaded fit of the second threaded hole 705 and the second screw 706, the second screw 706 is screwed to make the docking block 707 continuously approach the docking groove 701. During this process, the horizontal position of the snap-fit ​​plate 703 can be further slid and adjusted so that the docking block 707 and the docking groove 701 can be stably connected. As the second screw 706 continues to be screwed inward, the docking block 707 finally connects with the docking groove 701, thereby installing and fixing the partition plate 3 inside the side plate 2. Using the above-described method of fixing the partition 3, multiple partitions 3 are sequentially installed and fixed inside the side panel 2, forming multiple fixed compartments 4 inside the side panel 2.
