Description

Technical Field

[0001] This utility model belongs to the field of sheet pile limiting technology, and in particular relates to a sheet pile limiting guide frame. Background Technology

[0002] Reinforced concrete sheet piles, after being driven, form a composite pile body, making them an easily promoted type of pile foundation engineering with good soil displacement effect. Reinforced concrete sheet piles have advantages such as high structural strength, high rigidity, readily available materials, and simple construction. Their shape can be designed and manufactured according to requirements, and the tenon and groove structure can solve the problem of joint sealing and waterproofing. Reinforced concrete sheet piles are driven using methods such as hammering and hydraulic pressure.

[0003] During the driving of reinforced concrete sheet piles, a limiting structure is needed to squeeze and limit one side of the sheet pile, and the limiting mechanism needs to be kept in contact with the side of the sheet pile wall at the installation location; such as the composite precast sheet pile retaining structure disclosed in CN214657072U, which sets a slide rail on the retaining cross frame and slides inside the bottom support slide rail through movable casters. Although it solves the problem of rapid movement and fixation, the structure has the following disadvantages: (1) Due to the unique shape and size of the limiting slide plate and the limited track for matching, it cannot adapt to the limiting of reinforced concrete slabs of different thicknesses; (2) Due to the use of a slide plate with movable casters and the reliance on the positioning teeth blocks set on the slide plate. (2) The structure is relatively complex and the manufacturing cost is high because it meshes with the limiting rack on the retaining cross frame; (3) The retaining cross frame is a flat structure and is placed directly on the ground without any measures to fix the guide frame to the ground. During the driving of reinforced concrete sheet piles, the guide frame is prone to displacement due to the long reinforced concrete sheet piles, resulting in inaccurate positioning; (4) The existing guide frame lacks a lifting structure and does not have a guide frame leveling device. During the driving of the piles, the level of the guide frame cannot be checked. Once tilting occurs, it will easily cause the reinforced concrete sheet piles to tilt as well. Therefore, in view of the above problems, this solution proposes a sheet pile limiting guide frame. Utility Model Content

[0004] This utility model provides a sheet pile limiting guide frame, comprising two sets of transversely arranged H-shaped steel frames with flush end faces. The spacing is adjusted by adjusting bolts installed on the end-split mounting plates, accommodating the limiting of reinforced concrete slabs of different thicknesses. The guide frame uses two sets of H-shaped steel frames, with surface treatments such as drilling and welding connecting blocks. Compared to the complex structures of existing limiting racks and sliding plates with limiting teeth, the structure is simpler and has lower manufacturing costs. The guide frame is equipped with plug-in fixing rods installed via plug-in fixing plates. After the guide frame is placed at the desired pile driving position, the plug-in fixing rods are inserted into the ground, making the guide frame more stable and less prone to disengagement or displacement during pile driving, resulting in more precise positioning. The system is more accurate; the guide frame is also equipped with a hanging hook and a leveling device for easy lifting, lowering, and movement. The leveling device can observe whether the guide frame is level, thus providing real-time reference for leveling operations. The connecting and fixing blocks are fixed to the H-shaped steel frame with bolts. The fixing holes are evenly spaced on the H-shaped steel frame, allowing for the selection of the corresponding spacing of fixing holes to match the insertion bolts for installing the limiting rollers based on the width of the reinforced concrete sheet piles, adapting to the pile driving requirements of insertion bolts with different widths. The connecting and fixing blocks, connecting bolts, spacing adjustment bolts, insertion bolts, and insertion fixing rods in this solution can all be easily disassembled and assembled, making it convenient and quick to use. In summary, this solution solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a sheet pile limiting guide frame, comprising two sets of horizontally arranged H-shaped steel frames with flush end faces, spacing adjustment mounting plates set on the left and right sides of the H-shaped steel frames, spacing adjustment bolts installed through the two sets of spacing adjustment mounting plates, fixing mounting holes equally spaced on the upper inner side of the H-shaped steel frames, connecting fixing blocks detachably installed on the fixing mounting holes by connecting bolts, limiting rollers detachably installed between the left and right sets of connecting fixing blocks by locking nuts, and plug-in fixing rods vertically installed on the H-shaped steel frames.

[0007] After adjusting the spacing bolts, a spacer cavity is formed between the two sets of H-shaped steel frames to accommodate the insertion of reinforced concrete sheet piles, and the two outer side walls of the reinforced concrete sheet piles are in contact with the inner side walls of the H-shaped steel frames.

[0008] The limiting roller fits into the groove and tenon structure surface of the reinforced concrete sheet pile after installation;

[0009] The plug-in fixing rod passes through the plug-in fixing plate set on the H-shaped steel frame and the middle partition plate of the H-shaped steel frame before being inserted into the ground.

[0010] Furthermore, the width of the spacer cavity is consistent with that of the reinforced concrete sheet pile, and the spacing is adjusted by adjusting screws on the spacing adjustment bolts; the spacing adjustment bolts are long bolts with one end being a large end, and the adjusting screws are provided in three sets, which, after being adjusted by a wrench, respectively abut against the side walls of the two sets of spacing adjustment mounting plates for limiting.

[0011] Furthermore, the spacing of the fixing holes corresponds to the width of the reinforced concrete sheet pile; there are two sets of fixing holes, which correspond to the two sets of positioning holes on the connecting fixing block respectively. The connecting bolts are threaded to the positioning holes and the fixing holes to lock and fix the connecting fixing block.

[0012] Furthermore, the connecting fixing block is provided with a roller mounting hole above the fixing mounting hole. The limiting roller includes a plug bolt that passes through the roller mounting hole and a roller body sleeved on the plug bolt. The side of the roller body abuts and fits against the groove and tenon structure surface of the reinforced concrete sheet pile. The plug bolt is a long bolt with one end being a large end and the other end being limited by a lock nut.

[0013] Furthermore, the insertion fixing plate is positioned at both ends and the middle of the upper part of the H-shaped steel frame.

[0014] Furthermore, the plug-in fixing plate is provided with a hanging buckle.

[0015] Furthermore, a horizontal calibration device is installed on the plug-in fixing plate.

[0016] Furthermore, the bottom end of the plug-in fixing rod is spike-shaped, and the upper part of the plug-in fixing rod is provided with a circular positioning baffle larger than the through hole.

[0017] The present invention has the following advantages over the prior art:

[0018] (1) Adjustable spacing: This scheme includes two sets of horizontally arranged H-shaped steel frames with flush end faces. The spacing can be adjusted by the spacing adjustment bolts installed on the spacing adjustment mounting plate at both ends, which can adapt to the limit of reinforced concrete slabs of different thicknesses.

[0019] (2) Simple structure and lower manufacturing cost: The guide frame is arranged with two sets of H-shaped steel frames and the surface is treated by drilling and welding connecting blocks. Compared with the complex structure of existing technologies such as limit racks and slide plates with limit teeth, the structure is simpler and the manufacturing cost is lower.

[0020] (3) The guide frame is more stable in positioning: The guide frame is equipped with a plug-in fixing rod by plug-in fixing plate. After the guide frame is placed at the position where the pile needs to be driven, the plug-in fixing rod is inserted into the ground to make the guide frame more stable. During the pile driving process, it is not easy to dislodge or shift, and the position is more accurate.

[0021] (4) Easy to hoist and level: The guide frame is also equipped with a hook and a level calibration device, which makes it easy to hoist, lower and move. The level calibration device can observe whether the guide frame is level, thus providing a real-time reference for the leveling action.

[0022] (5) The width adaptability of reinforced concrete sheet piles is good: the connecting and fixing blocks are fixedly connected to the H-shaped steel frame with bolts, and the fixing and installation holes are arranged at equal intervals on the H-shaped steel frame. The fixing and installation holes with corresponding intervals can be selected according to the width of the reinforced concrete sheet piles to install the limiting rollers with the plug bolts, which can adapt to the pile driving requirements of reinforced concrete sheet piles of different widths.

[0023] (6) Easy installation and disassembly: The connecting fixing blocks, connecting bolts, spacing adjustment bolts, plug bolts and plug fixing rods of this solution can be easily installed and disassembled, making it convenient and quick to use.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0034] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] In the description of this utility model, it should be understood that the terms "left and right", "both sides", "end face", "spacing", "upper part", "inner side", "vertical", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Please see Figure 1-6 As shown, this utility model discloses a sheet pile limiting guide frame, comprising two sets of horizontally arranged H-shaped steel frames 1 with flush end faces, spacing adjustment mounting plates 11 set on the left and right sides of the H-shaped steel frames 1, spacing adjustment bolts 3 installed through the two sets of spacing adjustment mounting plates 11, fixing mounting holes 15 equally spaced on the upper inner side of the H-shaped steel frames 1, connecting fixing blocks 2 detachably installed on the fixing mounting holes 15 by connecting bolts 22, limiting rollers 4 detachably installed between the left and right sets of connecting fixing blocks 2 by locking nuts 41, and plug-in fixing rods 5 vertically installed on the H-shaped steel frames 1; the H-shaped steel frames 1 are existing H-shaped steel beams, and the spacing adjustment mounting plates 11 are welded to both ends; after the connecting bolts 22 are tightened, the front end will not abut against the side of the reinforced concrete sheet pile 6, that is, the length of its threaded rod is less than the sum of the thickness of the connecting fixing blocks 2 and the upper inner side of the H-shaped steel frames 1;

[0037] The reinforced concrete sheet pile 6 is an existing structure with mortise and tenon joints on both sides. One side is concave and the other side is a corresponding convex shape, which can be interlocked and connected.

[0038] After adjustment by the spacing adjustment bolts 3, a spacer cavity is formed between the two sets of H-shaped steel frames 1 to accommodate the insertion of reinforced concrete sheet piles 6, and the two outer side walls of the reinforced concrete sheet piles 6 are in contact with the inner side walls of the H-shaped steel frames 1.

[0039] After installation, the limiting roller 4 fits into the groove and tenon structure surface of the reinforced concrete sheet pile 6;

[0040] The insertion fixing rod 5 passes through the insertion fixing plate 12 set on the H-shaped steel frame 1 and the middle partition plate of the H-shaped steel frame 1 and then inserts into the ground; after the bottom of the insertion fixing rod 5 is inserted into the ground, it can maintain relative stability of the guide frame as a whole and reduce the displacement of the guide frame as a whole caused by the reinforced concrete sheet pile 6 during the pile driving operation.

[0041] The spacing cavity is the same width as the reinforced concrete sheet pile 6, and the spacing is adjusted by adjusting screws 31 on the spacing adjusting bolt 3. The spacing adjusting bolt 3 is a long bolt with a large end. The adjusting screws 31 are provided in three sets, which are adjusted by a wrench and then abut against the side walls of the two sets of spacing adjusting mounting plates 11 for limiting.

[0042] The spacing of the fixing holes 15 corresponds to the width of the reinforced concrete sheet pile 6; there are two sets of fixing holes 15, which correspond to the two sets of positioning holes 23 on the connecting fixing block 2 respectively; the connecting bolts 22 are threaded to the positioning holes 23 and the fixing holes 15 to lock and fix the connecting fixing block 2; the connecting fixing block 2 is installed on the outer side of the inner plate of the H-shaped steel frame 1.

[0043] In this specific embodiment, the reinforced concrete sheet pile 6 has a length of 500mm, a height of 12mm, and a thickness of 8cm. Other height parameters are also within the scope of this technical solution. Additionally, there are lengths of 1000mm and 250mm. To ensure the guide frame can accommodate all lengths, the spacing between adjacent sets of fixing holes 15 is 250mm, simultaneously accommodating the limiting requirements of reinforced concrete sheet piles 6 with lengths of 250mm, 500mm, and 1000mm. When using 500mm reinforced concrete sheet piles 6 for pile driving, the connecting fixing blocks 2 are arranged at intervals of one; when using 250mm reinforced concrete sheet piles 6 for pile driving, the connecting fixing blocks 2 are arranged continuously; and when using 500mm reinforced concrete sheet piles 6 for pile driving, the connecting fixing blocks 2 are arranged at intervals of two.

[0044] The connecting fixing block 2 is provided with a roller mounting hole 24 above the fixing mounting hole 15. The limiting roller 4 includes a plug bolt 42 that passes through the roller mounting hole 24 and a roller body sleeved on the plug bolt 42. The side of the roller body abuts and fits against the groove and tenon structure surface of the reinforced concrete sheet pile 6. The plug bolt 42 is a long bolt with one end being a large end and the other end being limited by a locking nut 41.

[0045] The insertion fixing plate 12 is located at both ends and the middle of the upper part of the H-shaped steel frame 1; as in this embodiment, it is arranged in the middle and on both sides of the H-shaped steel frame 1.

[0046] The plug-in fixing plate 12 is equipped with a hanging buckle 13. The hanging buckle 13 is designed to facilitate the hoisting of the guide frame by a crane when it enters the site, and to lift it off the site by a crane after the pile driving is completed.

[0047] The plug-in fixing plate 12 is equipped with a horizontal calibration device 14. In this specific embodiment, the horizontal calibration device 14 adopts a bubble level, which can determine whether the level is calibrated by whether the position of the bubble is in the center.

[0048] The bottom of the plug-in fixing rod 5 is spiked, and the upper part of the plug-in fixing rod 5 is provided with a circular positioning baffle 51 larger than the through hole. It is inserted into the ground by tapping, and the positioning baffle 51 can press the guide frame downward. The spike can also be set with barbed spikes to improve the grip. Of course, other forms of structures that can achieve plugging and gripping effects are all within the protection scope of this solution.

[0049] The working principle of this technical solution is as follows:

[0050] Two sets of H-shaped steel frames 1 are hoisted and moved to the required pile driving position via a crane and hoisting rope connected to the hanging buckle 13. Their positions are adjusted so that the two sets of H-shaped steel frames 1 are horizontally parallel and their ends are flush. Based on the thickness of the reinforced concrete sheet pile 6, the spacing is adjusted using the spacing adjustment bolts 3 and adjusting screws 31, ensuring that the spacing between the two sets of H-shaped steel frames 1 is just enough for the reinforced concrete sheet pile 6 to sink and pass through, and that the two outer side walls of the reinforced concrete sheet pile 6 are in contact with the inner side walls of the H-shaped steel frames 1. Then, the connecting fixing block 2 is fixed with the connecting bolts 22, and the limiting roller 4 is installed using the insertion bolts 42 and locking screws 41, so that the side of the roller body abuts against the groove and tenon structure surface of the reinforced concrete sheet pile 6. The insertion bolts 42 are long. Bolts are used, with one end being the larger end and the other end being limited by locking bolt 41; then, the top of the reinforced concrete sheet pile 6 is hammered and pressurized to make the reinforced concrete sheet pile 6 sink to the corresponding position; then the limiting roller 4 is removed, and new reinforced concrete sheet piles 6 are driven on the side of the previous reinforced concrete sheet pile 6, with the sides fitting together, and new limiting roller 4 is reinstalled until all reinforced concrete sheet piles 6 are installed, then the spacing adjusting bolts 3 are removed, the H-shaped steel frame 1 is lifted, and the pile driving is completed; during this process, the levelness is checked by a spirit level, and the guide frame is fixed by inserting the plug-in fixing rod 5 into the ground; after the pile driving is completed, the plug-in fixing rod 5 is pulled out, and the guide frame is moved away by the crane, completing the overall sheet pile driving work.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
