Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a steel sheet pile driving accuracy control device. Background Technology
[0002] In modern construction engineering, steel sheet piles are a commonly used support structure, widely used in foundation pit support, underground structure engineering, bridge construction and other fields. However, in the traditional steel sheet pile driving process, problems such as inaccurate positioning and difficulty in controlling verticality are often encountered, resulting in unstable construction quality and increasing the workload and cost of subsequent repairs. In addition, although some existing pile driving auxiliary devices can improve construction accuracy to a certain extent, they still have many shortcomings in complex geological conditions and variable construction site environments.
[0003] Chinese invention patent CN114934508B discloses a guide frame for improving the construction accuracy of Larssen sheet piles and its usage method. The guide frame includes a spacing adjustment device and two L-shaped supports. The two L-shaped supports are symmetrically arranged and connected by the spacing adjustment device. The spacing adjustment device includes a spacing adjustment disc and a limiting stop bar. The spacing adjustment disc is long and plate-shaped, with a through hole in the middle along its length. Each end has an outlet. A locking assembly is provided at the upper part of both ends of the through hole. Each locking assembly includes multiple locking slots arranged side-by-side. One locking slot in each assembly is selected to engage with the limiting stop bar installed on the L-shaped support. A Larssen sheet pile limiting device is suspended from the upper end of one of the L-shaped supports. This invention improves construction quality, solves the problems of precise positioning and verticality control during Larssen sheet pile construction, and further ensures construction quality and efficiency.
[0004] Although the above design achieves preliminary control over the spacing and position of sheet piles through the spacing adjustment device and limit stops, it still has certain limitations: the device mainly relies on mechanical spacing adjustment discs and limit stops, which has poor adaptability to sheet piles of different sizes and shapes, and cannot flexibly handle various specifications of sheet piles. During the piling process, if geological conditions change or the sheet piles shift, the device lacks the ability to adjust in real time and cannot correct deviations in time, affecting the final construction accuracy. The device does not provide a special treatment mechanism for the connection of sheet piles, and for projects requiring waterproofing or seepage prevention, it cannot ensure the tightness and sealing of the connection. Therefore, how to improve the adaptability of the sheet pile driving process, enhance the real-time adjustment capability, and optimize the connection treatment is an urgent problem to be solved. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a steel sheet pile driving accuracy control device to solve the above-mentioned problems.
[0006] The purpose of this utility model is achieved through the following technical solution: a steel sheet pile driving accuracy control device, including symmetrically arranged clamping mechanisms, each clamping mechanism including a base plate one, a base plate two fixedly connected to the base plate one, a core clamping plate and a cavity clamping plate rotatably connected to the base plate one and the base plate two respectively, the base plate one and the core clamping plate and the base plate two and the cavity clamping plate are fixedly connected by angle hydraulic cylinders, the base plate one and the base plate two are fixedly connected by multiple fixed hydraulic cylinders, the core clamping plate includes a symmetrically arranged core one and core two, the cavity clamping plate includes a symmetrically arranged cavity one and cavity two, the symmetrically arranged core one and core two and the cavity one and cavity two are provided with symmetrically arranged width hydraulic cylinders, the cavity one is provided with an adjusting block near the end of the core one, the cavity one and the adjusting block are provided with an adjusting hydraulic cylinder, the width hydraulic cylinder is a double-acting hydraulic cylinder, and the width hydraulic cylinder is connected to an external hydraulic system.
[0007] Through a hydraulic system and sliding connection design, the device can flexibly adapt to steel sheet piles of different sizes and shapes, ensuring high-precision positioning under various construction conditions. Utilizing the coordinated work of angle and width hydraulic cylinders, real-time feedback and automatic correction functions are achieved, ensuring timely correction of deviations during pile driving and maintaining the verticality and positional accuracy of the steel sheet piles. The addition of adjusting hydraulic cylinders and adjusting blocks allows for real-time correction and sealing of the steel sheet pile connections during pile driving, ensuring a tight and accurate connection. This is particularly suitable for projects requiring waterproofing or seepage prevention. The fixed gantry and fixed hydraulic cylinders enhance the overall rigidity and lateral force resistance of the device, ensuring stability even under complex geological conditions and improving construction safety and reliability. This invention improves the accuracy and construction quality of steel sheet pile driving and is applicable to a wide range of construction scenarios, especially suitable for projects with high requirements for construction quality and safety.
[0008] A fixed gantry is fixedly connected between the base plates of the two clamping mechanisms, and the top of the fixed gantry is fixedly connected to the external construction equipment.
[0009] The core clamping plate and the cavity clamping plate are both attached to the outer wall of the sheet pile at their closest points, and the cylinder body of the angle hydraulic cylinder is rotatably connected to the corresponding base plate one and base plate two.
[0010] The piston rod of the angle hydraulic cylinder is rotatably connected to the outer end of the width hydraulic cylinder body near the upper side of the core clamping plate and the cavity clamping plate, while the fixed hydraulic cylinder is connected to the external hydraulic system.
[0011] The piston rods of the width hydraulic cylinders on the core clamping plate and the cavity clamping plate are fixedly connected to the corresponding core and cavity. The core and cavity are provided with clearance grooves at the corresponding positions of the hydraulic pipes on the width hydraulic cylinder.
[0012] The bottom ends of core one, core two, cavity one and cavity two are all slidably connected to the corresponding base plate one and base plate two.
[0013] The cylinder body of the adjusting hydraulic cylinder is fixedly connected to the cavity, the piston rod of the adjusting hydraulic cylinder is fixedly connected to the adjusting block, and the end of the adjusting block away from the cavity is fitted to the connection point of the steel sheet pile.
[0014] The cylinder body of the fixed hydraulic cylinder is fixedly connected to the corresponding base plate one and base plate two. The piston rod of the fixed hydraulic cylinder passes through the corresponding base plate one and base plate two, and the passing part extends to the lower side of base plate one and base plate two.
[0015] The beneficial effects of this utility model are:
[0016] 1. By working in concert with the angle hydraulic cylinder and the width hydraulic cylinder, precise multi-point and multi-directional adjustments to the sheet pile can be achieved. The angle hydraulic cylinder can adjust the angle of the clamping plate to ensure that the sheet pile remains vertical during insertion. The width hydraulic cylinder can dynamically adjust the distance between the clamping plates according to the actual size of the sheet pile to ensure that the sheet pile fits tightly with the clamping plate. This multi-point coordinated adjustment mechanism significantly improves the accuracy of pile driving and reduces construction problems caused by positional deviations.
[0017] During the piling process, if the sheet pile deviates slightly, the angle hydraulic cylinder will respond immediately and push the corresponding core clamp and cavity clamp to rotate around the connection of the base plate, correcting the insertion direction of the sheet pile in real time. This real-time feedback mechanism enables the device to detect and correct deviations at the first moment, ensuring that each sheet pile can be accurately inserted into the predetermined position.
[0018] The design of the width hydraulic cylinder allows the distance between the clamps to be flexibly adjusted according to the actual size of the sheet pile. Whether the sheet pile is narrow or wide, this utility model can ensure that the clamps are tightly fitted to the outer wall of the sheet pile through the extension and retraction of the width hydraulic cylinder, thereby achieving high-precision control of sheet piles of different specifications.
[0019] 2. The bottom ends of the core and cavity are slidably connected to the base plate via sliders. This sliding connection design not only increases the range of motion of the clamping plate, but also allows the clamping plate to move freely within a certain range to adapt to different construction environments and geological conditions. For example, on soft soil foundations, the clamping plate can automatically adjust its position by sliding to avoid uneven clamping force caused by uneven ground.
[0020] The sliding connection design also gives the device greater flexibility, enabling it to adapt to complex construction environments. For example, when encountering sloping or irregular ground, the clamp can automatically adjust its posture by sliding to ensure a good fit with the sheet pile, thereby improving the success rate and quality of piling.
[0021] Because the clamping plate can move freely within a certain range, this invention can better adapt to minor errors during the installation process. Even if there is a slight deviation in the initial positioning, the clamping plate can automatically adjust to the optimal position by sliding, ensuring that the final position of the steel sheet pile is accurate.
[0022] 3. By extending the piston rod through the base plate and downwards, the fixed hydraulic cylinder firmly secures the base plate to the ground, preventing displacement or tilting of the device during pile driving. This design not only improves the stability of the device but also enhances construction safety, especially in applications requiring high-precision pile driving, such as bridge construction or underground structure engineering. The fixed hydraulic cylinder provides longitudinal fixation and effectively resists lateral forces. During pile driving, the lateral forces on the sheet piles may cause the device to shift, but the strong support of the fixed hydraulic cylinder effectively counteracts these lateral forces, ensuring the device remains stable. This is particularly important when dealing with deep or heavy sheet piles, significantly improving construction safety and reliability.
[0023] By firmly fixing the base plate to the ground, the fixing hydraulic cylinder can effectively reduce the impact of vibration generated during piling on the device. Vibration may cause the clamping plate to loosen or shift position, thus affecting the piling accuracy. The presence of the fixing hydraulic cylinder allows the device to remain stable in a vibrating environment, ensuring the smooth progress of the piling process. 4. The operation process of this utility model is relatively simple. Users only need to control the actions of each component through the external hydraulic system to complete the entire process from positioning to piling. For example, by issuing a command through the control system, the fixing hydraulic cylinder will automatically fix the base plate to the ground, and the angle hydraulic cylinder and width hydraulic cylinder will automatically adjust the position of the clamping plate according to the set parameters. This one-button operation method greatly reduces the difficulty of operation, reduces the possibility of human intervention, and improves work efficiency.
[0024] The entire control process of the device is highly automated. All hydraulic components are connected to an external hydraulic system and can automatically execute various actions according to preset programs. This not only improves the accuracy of operation, but also reduces the time and effort required for manual operation, making it particularly suitable for large-scale construction projects.
[0025] The base plate can be placed directly on the ground, and the fixing hydraulic cylinder can quickly fix the base plate in place without complicated installation tools or steps. Similarly, after the construction is completed, the fixing hydraulic cylinder can be quickly retracted, and the base plate can be easily removed, which provides convenience for subsequent construction.
[0026] 5. The design of the adjustable hydraulic cylinder and adjusting block enables the device to perform real-time correction of the steel sheet pile connection during the piling process. The adjusting block can detect and eliminate any deformation or defects that may occur at the connection, ensuring that each steel sheet pile can be connected with other steel sheet piles. This is crucial for ensuring construction quality, especially in projects that require high-strength connections.
[0027] The squeezing action of the adjusting block can effectively reduce the gaps at the joints of steel sheet piles, improve the tightness and sealing performance of the connection. For projects that require waterproofing or seepage prevention, this design can significantly reduce the risk of leakage and ensure the safety and durability of construction.
[0028] The design of the adjusting block is not only suitable for conventional piling projects, but also for some special working conditions, such as soft soil foundations or irregular terrain. By adjusting the control of the hydraulic cylinder, the adjusting block can flexibly adjust the pressure according to the actual situation to ensure that the quality of the connection always meets the requirements.

[0042] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0043] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here. Example
[0044] like Figures 1 to 11 As shown in the figure, this embodiment provides a basic sheet pile driving accuracy control device, the main structure and working principle of which are as follows:
[0045] The device includes symmetrically arranged clamping mechanisms, each of which consists of a base plate 1, a base plate 2, a core clamping plate 3, a cavity clamping plate 4, an angle hydraulic cylinder 5, and a fixed hydraulic cylinder 6.
[0046] A base plate 2 is fixedly connected to a base plate 1. A core clamping plate 3 and a cavity clamping plate 4 are rotatably connected to the base plate 1 and the base plate 2, respectively. These clamping plates are connected to the base plate 1 and the base plate 2 through an angle hydraulic cylinder 5, so that the clamping plates can be rotated and adjusted around the base plate.
[0047] The core clamping plate 3 includes a symmetrically arranged core 1 7 and a core 2 8, and the cavity clamping plate 4 includes a symmetrically arranged cavity 1 9 and a cavity 2 10. These components are provided with symmetrically arranged wide hydraulic cylinders 11 for adjusting the distance between the clamping plates to accommodate steel sheet piles of different sizes.
[0048] The width hydraulic cylinder 11 is a double-acting hydraulic cylinder and is connected to an external hydraulic system for precise control.
[0049] The fixed hydraulic cylinder 6 is installed on the base plate 1 and the base plate 2. The piston rod passes through the base plate and extends downward to fix the base plate to the ground and ensure the stability of the device.
[0050] One end of the core clamping plate 3 and the cavity clamping plate 4 is designed to fit against the outer wall of the sheet pile, ensuring close contact and guiding the insertion direction of the sheet pile.
[0051] The cylinder body of the angle hydraulic cylinder 5 is rotatably connected to the base plate 1 and the base plate 2, allowing the clamping plate to be adjusted in angle as needed.
[0052] The piston rod of the angle hydraulic cylinder 5 is rotatably connected to the outer end of the cylinder body of the width hydraulic cylinder 11 near the upper side on the core clamping plate 3 and the cavity clamping plate 4. This design makes the angle adjustment more flexible while maintaining the compactness of the structure.
[0053] The fixed hydraulic cylinder 6 is connected to the external hydraulic system to ensure timely response to operating commands and improve work efficiency.
[0054] The bottom ends of core 1 7, core 2 8, cavity 1 9 and cavity 2 10 are slidably connected to the corresponding base plate 1 1 and base plate 2 2 via slider 15. This design not only increases the flexibility of the device, but also allows the clamping plate to move freely within a certain range to adapt to different construction environments.
[0055] The cylinder body of the fixed hydraulic cylinder 6 is fixedly connected to the base plate 1 and the base plate 2. The piston rod passes through the base plate and extends downward. When the piston rod extends, it inserts into the ground, thereby firmly fixing the base plate to the ground and ensuring the stability and reliability of the device during the piling process.
[0056] Work process
[0057] First, the first sheet pile is driven into the ground, and then the device is placed on both sides of the driven sheet pile by means of a fixed gantry (not involved in this embodiment) or other methods.
[0058] Make contact with and press the bottom ends of multiple base plates 1 and 2 against the ground to ensure the initial positioning of the device.
[0059] The core clamping plate 3 and cavity clamping plate 4, which are close to the fixed gantry, are attached to both sides of the steel sheet pile by the angle hydraulic cylinder 5. The steel sheet pile that has been driven into the ground is used as a reference point to initially fix the device.
[0060] Next, the fixed hydraulic cylinder 6 is activated by the external hydraulic system, so that the piston rod is inserted into the ground to further fix the base plate 1 and the base plate 2, ensuring that the device will not shift during the piling process.
[0061] The wide hydraulic cylinder 11 is used to drive the corresponding core 7 and cavity 9, so that they fit tightly against the outer end of the sheet pile. This step ensures that the sheet pile is accurately positioned when inserted.
[0062] Place the bottom end of the second sheet pile to be inserted between the core clamping plate 3 and the cavity clamping plate 4, which are far away from the fixed gantry.
[0063] The corresponding core clamping plate 3 and cavity clamping plate 4 are attached to the outer end of the sheet pile by the corresponding angle hydraulic cylinder 5, and the pile driving is ready to begin.
[0064] During the piling process, the position of the core clamping plate 3 and the cavity clamping plate 4 is continuously adjusted by the width hydraulic cylinder 11 to ensure that the steel sheet pile is accurately inserted into the ground along the predetermined path.
[0065] If a deviation occurs, the angle hydraulic cylinder 5 will push the corresponding core clamping plate 3 and cavity clamping plate 4 to rotate around the connection between the base plate 1 and the base plate 2, thereby correcting the insertion direction of the sheet pile in real time.
[0066] Through the coordinated operation of the angle hydraulic cylinder 5 and the width hydraulic cylinder 11, this device can achieve precise multi-point and multi-directional adjustment of the sheet pile. Specifically, the angle hydraulic cylinder 5 can adjust the angle of the clamping plate to ensure that the sheet pile remains vertical during insertion; while the width hydraulic cylinder 11 can dynamically adjust the distance between the clamping plates according to the actual size of the sheet pile to ensure that the sheet pile and the clamping plate fit tightly. This multi-point coordinated adjustment mechanism significantly improves the accuracy of pile driving and reduces construction problems caused by positional deviations.
[0067] During the piling process, if the sheet pile deviates slightly, the angle hydraulic cylinder 5 will immediately respond and push the corresponding core clamping plate 3 and cavity clamping plate 4 to rotate around the connection between the base plate 1 and the base plate 2, correcting the insertion direction of the sheet pile in real time. This real-time feedback mechanism enables the device to detect and correct the deviation at the first time, ensuring that each sheet pile can be accurately inserted into the predetermined position.
[0068] The design of the width hydraulic cylinder 11 allows the distance between the clamping plates to be flexibly adjusted according to the actual size of the sheet pile. Whether the sheet pile is narrow or wide, this device can ensure that the clamping plates are tightly fitted to the outer wall of the sheet pile through the extension and retraction of the width hydraulic cylinder 11, thereby achieving high-precision control of sheet piles of different specifications.
[0069] The sliding connection design enhances adaptability: the bottom ends of core 1 7, core 2 8, cavity 1 9 and cavity 2 10 are slidably connected to base plate 1 1 and base plate 2 2 via slider 15. This sliding connection design not only increases the range of motion of the clamping plate, but also allows the clamping plate to move freely within a certain range to adapt to different construction environments and geological conditions. For example, on soft soil foundations, the clamping plate can automatically adjust its position by sliding, avoiding the problem of uneven clamping force caused by uneven ground.
[0070] The sliding connection design also gives the device greater flexibility, enabling it to adapt to complex construction environments. For example, when encountering sloping or irregular ground, the clamp can automatically adjust its posture by sliding to ensure a good fit with the sheet pile, thereby improving the success rate and quality of piling.
[0071] Because the clamping plate can move freely within a certain range, this device can better adapt to minor errors during the installation process. Even if there is a slight deviation in the initial positioning, the clamping plate can automatically adjust to the optimal position by sliding, ensuring that the final position of the sheet pile is accurate.
[0072] The design of the fixed hydraulic cylinder 6 is a key innovation of this device. By passing through the bottom plate 1 and the bottom plate 2 and extending downwards, the fixed hydraulic cylinder 6 can firmly fix the bottom plate to the ground, preventing the device from shifting or tilting during the piling process. This design not only improves the stability of the device, but also enhances the safety of construction, especially in situations requiring high-precision piling, such as bridge construction or underground structure engineering.
[0073] The use of the fixed hydraulic cylinder 6 not only provides longitudinal fixation but also effectively resists lateral forces. During the piling process, the lateral forces on the sheet pile may cause the device to shift, but the strong support of the fixed hydraulic cylinder 6 can effectively counteract these lateral forces, ensuring that the device remains stable. This is especially important when dealing with deeper or heavier sheet piles, and can significantly improve the safety and reliability of construction.
[0074] By firmly fixing the base plate 1 and the base plate 2 to the ground, the fixed hydraulic cylinder 6 can also effectively reduce the impact of vibration generated during the piling process on the device. Vibration may cause the clamping plate to loosen or shift its position, thus affecting the piling accuracy. The presence of the fixed hydraulic cylinder 6 enables the device to remain stable in a vibrating environment, ensuring the smooth progress of the piling process.
[0075] The operation of this device is relatively simple. Users only need to control the movement of each component through the external hydraulic system to complete the entire process from positioning to piling. For example, by issuing a command through the control system, the fixing hydraulic cylinder 6 will automatically fix the base plate to the ground, and the angle hydraulic cylinder 5 and the width hydraulic cylinder 11 will automatically adjust the position of the clamping plate according to the set parameters. This one-button operation greatly reduces the difficulty of operation, reduces the possibility of human intervention, and improves work efficiency.
[0076] The entire control process of the device is highly automated. All hydraulic components are connected to an external hydraulic system and can automatically execute various actions according to preset programs. This not only improves the accuracy of operation, but also reduces the time and effort required for manual operation, making it particularly suitable for large-scale construction projects.
[0077] Due to the simple structural design of the device, the installation and disassembly process is very convenient and quick. Base plate 1 and base plate 2 can be placed directly on the ground, and the fixing hydraulic cylinder 6 can quickly fix the base plate in place without complicated installation tools or steps. Similarly, after the construction is completed, the fixing hydraulic cylinder 6 can be quickly retracted, and the base plate can be easily removed, which provides convenience for subsequent construction.
[0078] Compared to more complex enhanced devices, this embodiment removes certain advanced functions, such as adjusting the hydraulic cylinder 13 and its related components, thereby simplifying the overall structure. This simplified design not only reduces manufacturing costs but also reduces maintenance and repair workload, making it particularly suitable for large-scale deployment.
[0079] Because the device has a relatively simple structure and the components work together more closely, it reduces wear and the risk of failure caused by complex mechanical movements. The strong support of the fixed hydraulic cylinder 6 also enables the device to maintain good performance in harsh construction environments, thus extending its overall service life.
[0080] The simplified design and efficient automated operation significantly reduce the operating costs of this device. On the one hand, it reduces the need for manual operation and lowers labor costs; on the other hand, the automated control system reduces the energy consumption and maintenance frequency of the equipment, further reducing operating costs. Example
[0081] like Figures 1 to 11 As shown, this embodiment expands upon the functionality of embodiment 1 by adding a fixed gantry 14, a more refined width adjustment mechanism, and special treatment for the connection of the sheet piles. The following is a detailed description of the structural composition and working principle:
[0082] This embodiment retains the components from Embodiment 1, including base plate 1, base plate 2, core clamping plate 3, cavity clamping plate 4, angle hydraulic cylinder 5, fixing hydraulic cylinder 6, core 1 7, core 2 8, cavity 1 9, cavity 2 10, width hydraulic cylinder 11, adjusting block 12, adjusting hydraulic cylinder 13, and slider 15.
[0083] A fixed gantry 14 was added, and the base plates 1 on the two clamping mechanisms are fixedly connected to each other through the fixed gantry 14. The top of the fixed gantry 14 is fixedly connected to external construction equipment (such as a crane or pile driver), which enhances the stability and ease of operation of the entire device.
[0084] In this embodiment, the piston rods of the width hydraulic cylinders 11 on the core clamping plate 3 and the cavity clamping plate 4 are fixedly connected to the corresponding core 7 and cavity 9. This direct connection method allows the width hydraulic cylinders 11 to more accurately control the positions of the core 7 and cavity 9, ensuring that they fit tightly against the outer wall of the sheet pile.
[0085] To accommodate the arrangement of hydraulic lines, clearance grooves are provided at the corresponding positions of the hydraulic lines on the core-7 and cavity-9 and the width hydraulic cylinder 11. These clearance grooves not only avoid interference between the hydraulic lines and the clamping plate, but also improve the overall compactness of the device and reduce unnecessary space occupation.
[0086] The cylinder body of the adjusting hydraulic cylinder 13 is fixedly connected to the cavity 9, and the piston rod is fixedly connected to the adjusting block 12. The end of the adjusting block 12 away from the cavity 9 is fitted to the connection of the sheet pile. This design allows the adjusting block 12 to perform real-time correction and sealing of the connection of the sheet pile during the piling process.
[0087] The main function of the adjusting block 12 is to correct any deformation or defects that may occur at the connection of the sheet piles, and to reduce the gap at the connection by squeezing, so as to ensure that the connection between the sheet piles is tight and correct. This is especially important in projects that require waterproofing or seepage prevention, and can significantly improve the construction quality.
[0088] Work process
[0089] First, the first sheet pile is driven into the ground. Then, the device is placed on both sides of the driven sheet pile through the fixing gantry 14. The top of the fixing gantry 14 is fixedly connected to external construction equipment (such as a crane or pile driver) to ensure that the device remains stable throughout the construction process.
[0090] The bottom ends of multiple base plates 1 and 2 are brought into contact with the ground and pressed firmly to the ground to initially position the device.
[0091] The core clamping plate 3 and cavity clamping plate 4, which are close to the fixed gantry 14, are attached to both sides of the steel sheet pile by the angle hydraulic cylinder 5. The steel sheet pile that has been driven into the ground is used as a reference point to initially fix the device.
[0092] Next, the fixed hydraulic cylinder 6 is activated by the external hydraulic system, so that the piston rod is inserted into the ground to further fix the base plate 1 and the base plate 2, ensuring that the device will not shift during the piling process.
[0093] The width hydraulic cylinder 11 is used to drive the corresponding core 7 and cavity 9, so that they fit tightly against the outer end of the sheet pile. Since the piston rod of the width hydraulic cylinder 11 is directly fixedly connected to the core 7 and cavity 9, this design makes the width adjustment more precise, ensuring that the sheet pile is accurately positioned when inserted.
[0094] Place the bottom end of the second sheet pile to be inserted between the core clamping plate 3 and the cavity clamping plate 4, away from the fixed gantry 14.
[0095] The corresponding core clamping plate 3 and cavity clamping plate 4 are attached to the outer end of the sheet pile by the corresponding angle hydraulic cylinder 5, and the pile driving is ready to begin.
[0096] During the piling process, the position of the core clamping plate 3 and the cavity clamping plate 4 is continuously adjusted by the width hydraulic cylinder 11 to ensure that the steel sheet pile is accurately inserted into the ground along the predetermined path.
[0097] If a deviation occurs, the angle hydraulic cylinder 5 will push the corresponding core clamping plate 3 and cavity clamping plate 4 to rotate around the connection between the base plate 1 and the base plate 2, thereby correcting the insertion direction of the sheet pile in real time.
[0098] During the piling process, the adjusting hydraulic cylinder 13 will push the adjusting block 12 as needed to fit it against the connection of the two steel sheet piles. The adjusting block 12 will correct the connection, eliminate any possible deformation or defects, and reduce the gap at the connection by squeezing, ensuring that the connection between the steel sheet piles is tight and correct.
[0099] For projects requiring waterproofing or leak prevention, the squeezing action of the adjusting block 12 can effectively reduce the risk of leakage at the joints and improve construction quality.
[0100] The design of the fixed gantry 14 significantly enhances the rigidity and stability of the entire device. By fixing the base plates 1 of the two clamping mechanisms together and connecting them to external construction equipment, the fixed gantry 14 provides additional support points for the device, preventing displacement or tilting caused by external forces. This design is particularly suitable for applications requiring high-precision piling, such as bridge construction or underground structure engineering, ensuring the safety and reliability of construction.
[0101] The presence of the fixed gantry 14 not only provides longitudinal fixation but also effectively resists lateral forces. During the piling process, the lateral forces on the sheet piles may cause the device to shift, but the strong support of the fixed gantry 14 can effectively counteract these lateral forces, ensuring that the device remains stable at all times.
[0102] The piston rod of the width hydraulic cylinder 11 is directly fixedly connected to the core 7 and the cavity 9, making the width adjustment faster and more precise. This design reduces the error transmission in the intermediate links, ensuring that the clamping plate can quickly respond to the instructions of the hydraulic system and achieve precise control of the sheet pile.
[0103] The core 7 and cavity 9 are provided with clearance grooves at the corresponding positions of the hydraulic pipes on the width hydraulic cylinder 11, which avoids interference between the hydraulic pipes and the clamping plate and improves the overall compactness of the device. This design not only saves space but also simplifies maintenance and reduces the possibility of failure.
[0104] The design of the adjusting hydraulic cylinder 13 and the adjusting block 12 enables the device to perform real-time correction of the steel sheet pile connection during the piling process. The adjusting block 12 can detect and eliminate any deformation or defects that may occur at the connection, ensuring that each steel sheet pile can be perfectly connected with other steel sheet piles. This is crucial for ensuring construction quality, especially in projects that require high-strength connections.
[0105] The squeezing action of the adjusting block 12 can effectively reduce the gap at the connection of the sheet piles, improve the tightness and sealing performance of the connection. For projects that require waterproofing or seepage prevention, this design can significantly reduce the risk of leakage and ensure the safety and durability of construction.
[0106] The design of the adjusting block 12 is not only suitable for conventional piling projects, but can also cope with some special working conditions, such as soft soil foundations or irregular terrain. By adjusting the control of the hydraulic cylinder 13, the adjusting block 12 can flexibly adjust the pressure according to the actual situation to ensure that the quality of the connection always meets the requirements.
[0107] The control system in this embodiment is highly automated. All hydraulic components are connected to an external hydraulic system and can automatically perform various actions according to a preset program. For example, the installation and disassembly of the fixed gantry 14 can be completed with one click through the control system, reducing the possibility of manual intervention and improving work efficiency.
[0108] The design of the fixed gantry 14 makes the installation and disassembly of the device very convenient and quick. The base plate 1 and the base plate 2 can be placed directly on the ground, and the fixed gantry 14 can quickly fix the base plate in place without complicated installation tools or steps. Similarly, after the construction is completed, the fixed gantry 14 can be quickly disassembled, and the base plate can be easily removed, which provides convenience for subsequent construction.
