[0002] As is well known, in some engineering construction processes, it is often necessary to install steel sheet pile structures inside the foundation pit to maintain the internal space of the pit and ensure its stability. Currently, when installing steel sheet piles, it is necessary to first install a positioning structure to improve the flatness of the steel sheet pile installation and prevent the steel sheet piles from tilting.

[0003] Utility model patent CN221895791U discloses a positioning device for steel sheet pile construction in foundation pit support, belonging to the technical field of steel sheet pile positioning in foundation pit support. It addresses the limitations of existing technologies, such as the inability to adjust the positioning space according to actual conditions, which restricts the positioning of steel sheet piles and limits their applicability. Furthermore, it often requires manual adjustment of the positioning range between two steel sheet piles, making the adjustment process cumbersome and inconvenient. The device includes a positioning base fixed to the bottom of the inner side of the foundation pit, and support steel sheet piles for supporting the inner walls of both sides of the foundation pit. The bottom of the positioning base is fixedly connected to multiple positioning pile heads for insertion and positioning at the bottom of the inner side of the foundation pit. This utility model not only facilitates the positioning of support sheet piles in the foundation pit, but also allows the positioning blocks on both sides to move closer or further apart by driving the worm gear to rotate forward and backward via a drive motor. This enables the positioning space between the two support sheet piles to be adjusted according to the actual situation during use, reducing limitations in the positioning process. It not only improves the applicability but also effectively ensures the stability of the support sheet piles.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A sheet pile positioning device for foundation pit support in municipal road pipeline network renovation includes: a base plate 1; sheet pile bodies 2 are provided on both sides of the top of the base plate 1, and two gantry frames 3 are provided between the two sheet pile bodies 2. The bottom ends of the two gantry frames 3 are fixedly connected to the base plate 1, and the two gantry frames 3 are fixedly connected to each other by a crossbeam 4. Limiting buckles 5 are provided at the four corners of the sheet pile bodies 2; each limiting buckle 5 is provided with a disassembly and assembly mechanism 6 for quick installation and positioning of the sheet pile bodies 2; a lifting mechanism 7 is provided at the bottom center of the crossbeam 4 to adjust the construction range between the two sheet pile bodies 2. The user fixes the base plate 1 at the center of the bottom of the foundation pit, and then quickly installs and positions the sheet pile bodies 2 by means of the disassembly and assembly mechanism 6 inside the limiting buckles 5. Finally, the lifting mechanism 7 controls the two sheet pile bodies 2 on both sides to move towards the inner wall of the foundation pit at the same time until the sheet pile bodies 2 are tightly attached to the inner wall of the foundation pit.

[0027] like Figure 3 and Figure 4 As shown, the disassembly and assembly mechanism 6 includes: U-shaped limiting grooves 8 are provided inside each limiting buckle 5; U-shaped fixing rods 9 are provided inside each U-shaped limiting groove 8; both ends of the U-shaped fixing rods 9 are fixedly connected to the sheet pile body 2; two limiting buckles 5 are fixedly connected by a first connecting rod 10; three second connecting rods 11 are provided between the two first connecting rods 10; both ends of the three second connecting rods 11 are fixedly connected to the first connecting rods 10 respectively; buckles 12 are provided at the top of each U-shaped fixing rod 9; arc-shaped grooves 13 are provided at the bottom of each buckle 12; a rotating rod 14 is fixedly connected to one side of each buckle 12; a first rotating shaft 15 is fixedly connected to the bottom end of each rotating rod 14; both ends of the first rotating shaft 15 are rotatably connected to the limiting buckles 5; the user aligns the U-shaped fixing rods 9 on the sheet pile body 2 with the U-shaped limiting grooves 8 of the limiting buckles 5, and then releases the sheet pile body 2; the sheet pile body 2... As the sheet pile body 2 moves downward due to its own weight, it also drives the U-shaped fixing rod 9 downward, causing the U-shaped fixing rod 9 to move downward inside the U-shaped limiting groove 8. As the U-shaped fixing rod 9 moves downward, it is pressed against the buckle 12 by the inclined surface of the buckle 12. The buckle 12 acts on the top of the rotating rod 14, causing the rotating rod 14 to rotate outward about the limiting buckle 5 with the first rotating shaft 15 as the center. At the same time, the sheet pile body 2 and the U-shaped fixing rod 9 continue to move downward. When the U-shaped fixing rod 9 descends to the bottom of the U-shaped limiting groove 8, the rotating rod 14 rotates back to its original position with the first rotating shaft 15 as the center, thereby causing the buckle 12 to move to the top of the U-shaped fixing rod 9 and fix the U-shaped fixing rod 9 inside the U-shaped limiting groove 8. This achieves the purpose of installing and positioning the sheet pile body 2. When it is necessary to disassemble the sheet pile body 2, simply press one side of the rotating rod 14 diagonally downward.

[0028] like Figure 3As shown, a fixing block 16 is fixedly connected to the side of the limiting buckle 5 away from the rotating rod 14. A spring 17 is provided between the fixing block 16 and the rotating rod 14. Connecting blocks 18 are fixedly connected to both ends of the spring 17. The two connecting blocks 18 are fixedly connected to the fixing block 16 and the rotating rod 14 respectively, and can apply tension to the rotating rod 14.

[0029] like Figure 5 As shown, the lifting mechanism 7 includes: a lifting block 19 disposed at the bottom center of the crossbeam 4; a second rotating shaft 20 fixedly connected to both sides of the lifting block 19; a linkage rod 21 rotatably connected to the outer surface of the middle part of the second rotating shaft 20; a third rotating shaft 22 rotatably connected to the end of the linkage rod 21 away from the second rotating shaft 20; linkage blocks 23 fixedly connected to the outer surfaces of both ends of the third rotating shaft 22; and linkage blocks 23 fixedly connected to the second connecting rod 11 respectively; a screw 24 threadedly connected inside the lifting block 19; the bottom end of the screw 24 rotatably connected to the base plate 1; and the top end of the screw 24 penetrating the crossbeam 4 and extending to the electric... At machine 25, motor 25 is fixedly connected to crossbeam 4, and screw 24 is fixedly connected to the output end of motor 25. When motor 25 is started, the output end of motor 25 drives screw 24. While screw 24 rotates, it controls lifting block 19 to move downward. While lifting block 19 moves downward, it drives second rotating shaft 20. Second rotating shaft 20 presses the top of linkage rod 21, causing the bottom of linkage rod 21 to continuously push third rotating shaft 22. Third rotating shaft 22 drives linkage block 23. Linkage block 23 pushes steel sheet pile body 2 through second connecting rod 11, causing two steel sheet pile bodies 2 to move simultaneously towards the inner wall of the foundation pit.

[0030] like Figure 5 As shown, both sides of the lifting block 19 are fixedly connected to sliders 26, and the inside of each slider 26 is slidably connected to a slide rod 27. The two ends of the slide rod 27 are fixedly connected to the base plate 1 and the crossbeam 4 respectively, which can limit the lifting block 19 and enable the lifting block 19 to perform flexible vertical lifting and lowering movements.

[0031] like Figure 2 As shown, each of the two second connecting rods 11 has two limiting rods 28 fixedly connected to the side away from the sheet pile body 2. The end of the limiting rod 28 away from the second connecting rod 11 passes through the gantry frame 3 and extends to the limiting block 29. The limiting block 29 is fixedly connected to the limiting rod 28, and the limiting rod 28 is slidably connected to the gantry frame 3. This can limit the sheet pile body 2, allowing the sheet pile body 2 to slide flexibly horizontally.

[0032] like Figure 1 and Figure 2 As shown, several pins 30 are evenly fixedly connected to the bottom of the base plate 1. The pins 30 can be inserted into the soil to fix the bottom of the device.

[0033] Working principle: The user fixes the base plate 1 to the center of the bottom of the pit using the pin 30, then aligns the U-shaped fixing rod 9 on the sheet pile body 2 with the U-shaped limiting groove 8 of the limiting buckle 5, and then releases the sheet pile body 2. Due to its own weight, the sheet pile body 2 moves downward. As the sheet pile body 2 moves downward, it drives the U-shaped fixing rod 9, causing the U-shaped fixing rod 9 to move downward inside the U-shaped limiting groove 8. As the U-shaped fixing rod 9 moves downward, it is pressed against the buckle 12 by the inclined surface of the buckle 12. The buckle 12 acts on the top of the rotating rod 14, causing the rotating rod 14 to rotate outward about the limiting buckle 5 with the first rotating shaft 15 as the center. At the same time, the sheet pile body 2 and the U-shaped fixing rod 9 continue to move downward. When the U-shaped fixing rod 9 descends to the bottom of the U-shaped limiting groove 8, the force on the buckle 12 disappears, and the spring 17 pulls the middle of the rotating rod 14 through the connecting block 18, causing the rotating rod 14 to... Rotating and resetting the first rotating shaft 15 as the center, the buckle 12 moves to the top of the U-shaped fixing rod 9, fixing the U-shaped fixing rod 9 inside the U-shaped limiting groove 8, thus achieving the purpose of installing and positioning the sheet pile body 2. When the sheet pile body 2 needs to be disassembled, simply press one side of the rotating rod 14 diagonally downwards. This simplifies the installation and positioning process of the sheet pile, allowing users to quickly install and position the sheet pile without the aid of tools, improving user efficiency. It solves the problem that although the existing sheet pile positioning device for foundation pit support in municipal road pipeline renovation can install and position the sheet pile, its bolt-based installation and positioning method requires users to use tools to tighten the bolts, and the bolt tightening process is time-consuming, resulting in a complicated installation and positioning process and low work efficiency.

[0034] The motor 25 is started, and its output drives the screw 24. As the screw 24 rotates, it controls the lifting block 19 to move downward. As the lifting block 19 moves downward, it drives the second rotating shaft 20. The second rotating shaft 20 presses against the top of the linkage rod 21, causing the bottom of the linkage rod 21 to continuously push the third rotating shaft 22. The third rotating shaft 22 drives the linkage block 23, which pushes the sheet pile body 2 through the second connecting rod 11. The sheet pile body 2 drives the limiting rod 28, causing the limiting rod 28 to slide inside the gantry frame 3. This allows both sheet pile bodies 2 to move simultaneously towards the inner wall of the pit. The user can adjust the spacing between the two sheet piles according to the width of the pit, so that the two sheet piles fit against the inner wall of the pit, improving the stability of the support device. This device is suitable for pits of different widths, thus improving its practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
