Description

Technical Field

[0001] This invention relates to the field of sheet pile construction technology, and in particular to a device and construction method for controlling the verticality of sheet piles in water-adjacent land areas. Background Technology

[0002] Sheet piles are a widely used support structure with advantages such as rapid construction, good water-stopping effect, and recyclability. They are often used in projects such as cofferdams for building islands near water and excavating foundation pits near water, serving as both support structures and water-stop curtains. During sheet pile construction, vibratory hammers or sheet pile drivers are used to drive the piles from top to bottom. The sheet piles are connected to each other by interlocking. During the driving process, guide frames are usually used to control the verticality of the sheet piles by limiting their movement forward and backward. However, when constructing sheet piles on land near water, it is difficult to install guide frames on the water-facing side, making it impossible to control the verticality of the sheet piles through forward and backward limiting. Furthermore, due to the proximity to the riverbank, the water and soil pressure on both sides of the sheet pile is unbalanced, causing the sheet piles to tend to tilt towards the water-facing side, resulting in excessive verticality deviation and affecting construction quality. Summary of the Invention

[0003] The main objective of this invention is to provide a verticality control device and construction method for steel sheet piles in water-adjacent land areas, thereby solving the problem that it is difficult to set up a single-sided verticality control device for steel sheet piles in water-adjacent land areas, which affects the construction quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a verticality control device for steel sheet piles in waterfront land areas, wherein a moving track is provided parallel to the shore at intervals along the driving trajectory of the steel sheet piles, and the bottom of the support frame is slidably connected to the moving track. The rear end of the three sets of guide components is connected to the front side of the support frame, and the front end abuts against the surface of the steel sheet pile. The three sets of guide components correspond to the upper abutment height of the newly driven steel sheet pile, the lower abutment height of the newly driven steel sheet pile, and the middle abutment height of the adjacent driven steel sheet pile, respectively. Each guide assembly includes two parallel hydraulic cylinders, the top of the piston rod of the hydraulic cylinder is rotatably connected to the roller, and the roller abuts against the surface of the steel sheet pile. The top of the support frame is equipped with a traction unit, including a traction platform, a winch and a wire rope. The winch is fixed on the traction platform. One end of the wire rope is wound on the winch and the other end is connected to the top of the sheet pile. The winch drives the wire rope to tension the sheet pile and adjust its verticality.

[0005] In the preferred embodiment, the rear ends of the three sets of guide components are connected to the three vertices of the rotating frame of the equilateral triangle structure, which is used to switch the contact position of the guide components by rotating the rotating frame. The front end of the support frame has two vertical and parallel guide frames on both sides. Multiple horizontal bars are arranged horizontally and parallel between the guide frames. The horizontal bars include a first horizontal bar, a second horizontal bar, and a third horizontal bar. The rear ends of the three sets of guide components pass through the rotating frame and are fixed on the first horizontal bar, the second horizontal bar, and the third horizontal bar respectively, for adjusting the abutment height of the guide components.

[0006] In the preferred embodiment, the rear ends of the two hydraulic cylinders of each guide assembly are fixedly connected to both ends of the connecting plate, and a rotating drum is provided in the middle of the rear end of the connecting plate; Rotating sleeves are provided at each of the three vertices of the rotating frame. The rotating sleeves are fitted inside the rotating sleeves to realize the rotational connection between the guide component and the rotating frame. The rotating sleeve has an annular groove in the middle, and the rotating cylinder has a convex ring in the middle that matches the annular groove. The axial positioning of the guide component and the rotating frame is achieved through the cooperation of the annular groove and the convex ring.

[0007] In the preferred embodiment, a rotating rod is also provided on the rear side of the guide assembly. A positioning key is provided on the circumference of the top of the rotating rod. A positioning groove adapted to the positioning key is provided on the inner wall of the rotating cylinder. The rotating rod drives the guide assembly to rotate around the rotation axis of the rotating sleeve through the key of the positioning key and the keyway of the positioning groove, so as to adjust the angle of the guide assembly.

[0008] In the preferred embodiment, the crossbar has an elongated hole along its length that matches the diameter of the rotating rod. The two ends and the end of the elongated hole are provided with slots. The rear end of the rotating rod slides along the elongated hole and is engaged in the slots to achieve positioning. The rear end of the rotating rod is provided with an external thread, and the front and rear sides of the crossbar are provided with locking nuts. The two locking nuts are threadedly connected to the external thread at the rear end of the rotating rod, and are used to lock the angle and position of the rotating rod by clamping the crossbar.

[0009] In the preferred embodiment, the length of the oblong hole is twice the height of the equilateral triangle of the rotating frame.

[0010] In the preferred embodiment, four sets of pins are symmetrically arranged on the guide frame. The pins pass through the guide frame and are inserted into the crossbar to fix the relative height of the crossbar. The four sets of pins correspond to the following heights: the upper abutment height of the newly driven sheet pile, the lower abutment height of the newly driven sheet pile, the middle abutment height of the adjacent driven sheet pile, and a reserved height that is lower than the lower abutment height of the newly driven sheet pile and is spaced at a distance equal to half the side length of the equilateral triangle of the rotating frame.

[0011] In the preferred embodiment, a meter counter and a tension sensor are installed on the winch to detect the pulling length and tension of the wire rope.

[0012] A construction method for a steel sheet pile verticality control device for water-adjacent land areas, the method comprising: S1. Level the construction site, complete the survey and layout according to the steel sheet pile construction line, and determine the steel sheet pile driving trajectory and the laying position of the moving track. S2. Lay the moving track according to the layout position, level and calibrate the moving track, and after the levelness and straightness meet the standards, install the support frame onto the moving track. S3. Drive a steel sheet pile horizontally at the construction position of the first steel sheet pile as a positioning guide pile. Weld a lifting ring to the top of the positioning guide pile, and tie the steel wire rope to the positioning guide pile through the lifting ring. Use a vibratory hammer to drive the first steel sheet pile to the preset depth. S4. Install the guide component at the corresponding midpoint of the first steel sheet pile that has been driven into place, and adjust the length of the hydraulic cylinder so that the roller at the front end of the guide component is tangentially attached to the surface of the first steel sheet pile. S5. Start the winch to tighten the wire rope connecting the first sheet pile, and adjust the inclination of the top of the sheet pile to ensure that its verticality meets the standard. S6. Hoist the second sheet pile and insert it into the soil along the locking mechanism of the first sheet pile. When the insertion depth reaches about 1m, install the guide components corresponding to the upper and lower abutment heights. After fixing, adjust the length of the hydraulic cylinder so that the roller is tangentially attached to the surface of the second sheet pile. Use a vibratory hammer to drive the second sheet pile to the design depth. S7. Hoist the third sheet pile and insert it into the soil along the locking mechanism of the second sheet pile. When the insertion depth reaches about 1m, rotate the frame and adjust the height of the crossbar. Switch each set of guide components to the next set of abutment positions and adjust the length of the hydraulic cylinder. Move the support frame forward one construction position along the moving track. Adjust the inclination of the top of the sheet pile by tightening the wire rope with the winch. S8. Repeat step S7 to continue moving forward and completing the subsequent sheet pile driving operation until the overall construction is completed.

[0013] In the preferred embodiment, step S7 includes: S71. Loosen the locking nuts on the side of the three sets of guide components closest to the sheet pile, and pull back the rotating rods at the upper and middle abutment heights to disengage the positioning key from the keyway of the positioning groove on the inner wall of the rotating cylinder. S72. Using the guide component at the lower abutment height as the axis, rotate the rotating frame 120 degrees, so that the guide component originally corresponding to the middle abutment height is switched to the upper abutment component of the new steel sheet pile, and the guide component originally corresponding to the upper abutment height is switched to the lower abutment component of the new steel sheet pile. S73. Move the rotating rod forward, re-insert the positioning key into the positioning groove on the inner wall of the rotating drum, and adjust the angle of each group of guide components until the two hydraulic cylinders are horizontally against each other. S74. Adjust the length of the hydraulic cylinder of the guide assembly that is switched to the new lower abutment height only, so that the rollers fit against the surface of the sheet pile. S75. Disconnect the first crossbar from the guide assembly and move it to a reserved height that is lower than the lower abutment height of the newly driven steel sheet pile and the spacing is half the side length of the equilateral triangle of the rotating frame. Then reconnect the guide assembly at the corresponding lower abutment height to the first crossbar. S76. Move the first crossbar, the second crossbar, and the third crossbar, along with the rotating frame and the three sets of guide components, upwards by half the side length of the equilateral triangle of the rotating frame and lock them with pins. S77. Slide the support frame along the moving track to the next construction position and lock the position and angle of each set of guide components; S76. Fix the wire rope to the top of the current sheet pile, start the winch to pull and tension, and complete the verticality adjustment of the sheet pile.

[0014] This invention provides a verticality control device and construction method for sheet piles in water-adjacent land areas, effectively solving the problems of difficulty in setting up guide frames on one side and difficulty in verticality control of sheet piles in water-adjacent land areas, and significantly improving construction quality and efficiency. The device provides a stable and precise moving reference for the support frame by setting a moving track parallel to the driving trajectory of the sheet piles on the bank side, ensuring that parallelism with the construction trajectory is maintained at all times during work position changes, avoiding the drawback of losing the reference after movement in traditional devices. Three sets of guiding components limit the sheet piles from different heights, and in conjunction with the tensioning control of the top traction unit, effectively balance the unbalanced water and soil pressure on both sides of the water-adjacent land area, suppressing the sheet piles from tilting towards the water-adjacent side, and significantly improving the accuracy of verticality control.

[0015] The connection design between the guide assembly and the equilateral triangle rotating frame allows for rapid switching of the guide assembly's contact position without needing to readjust the length parameters of all components. It retains the positioning foundation from the previous construction phase, significantly reducing adjustment workload. The mating structure of the rotating cylinder and rotating sleeve ensures the flexibility of the guide assembly's rotation while providing reliable axial limiting through the grooved ring, preventing displacement or detachment during construction. The engagement of the rotating rod with the positioning key and positioning groove allows for precise adjustment of the guide assembly's angle, ensuring the hydraulic cylinder remains in a horizontal contact position and improving fitting accuracy. The elongated hole and slot design on the crossbar provide ample space for adjusting the guide assembly's position, and the bidirectional locking of the locking nut provides dual fixation of position and angle, ensuring construction stability.

[0016] The winch is equipped with a meter counter and a tension sensor, which can monitor the pulling length and tension in real time. This prevents over-tensioning from causing deformation of the sheet pile or insufficient tension from affecting the control effect. Combined with relevant control modules, it can achieve automated control, reduce human error, and improve construction consistency. The corresponding construction method is coherent, leveraging the structural advantages of the device to achieve continuous construction. Initial benchmarks are established through positioning guide piles, and subsequent reuse of the guide components and pulling units requires only minor adjustments to achieve verticality control of the new sheet piles. This simplifies the construction process, improves efficiency, and is suitable for various sheet pile support projects in water-adjacent land areas, balancing stability and practicality.

[0019] Example 1 like Figure 1-9 As shown, a verticality control device for steel sheet piles in a water-adjacent land area is provided. A moving track 2 is provided parallel to the shore at intervals along the driving trajectory of the steel sheet pile 1. The bottom of the support frame 3 is slidably connected to the moving track 2. The rear end of the three sets of guide components 4 is connected to the front side of the support frame 3, and the front end abuts against the surface of the steel sheet pile 1. The three sets of guide components 4 correspond to the upper abutment height of the newly driven steel sheet pile 1, the lower abutment height of the newly driven steel sheet pile 1, and the middle abutment height of the adjacent driven steel sheet pile 1, respectively. Each guide assembly 4 includes two parallel hydraulic cylinders 401. The top of the piston rod of the hydraulic cylinder 401 is rotatably connected to the roller 402, and the roller 402 abuts against the surface of the sheet pile 1. The top of the support frame 3 is equipped with a traction unit 5, which includes a traction platform 501, a winch 502 and a wire rope 503. The winch 502 is fixed on the traction platform 501. One end of the wire rope 503 is wound on the winch 502 and the other end is connected to the top of the sheet pile 1. The winch 502 drives the wire rope 503 to tension the sheet pile 1 and adjust its verticality.

[0020] The device comprises a moving track 2, a support frame 3, a guide assembly 4, a traction unit 5, a rotating frame 6, a guide frame 7, a crossbar 8, a rotating rod 9, a locking nut 10, and a pin 11. These components work together to achieve verticality control and efficient workstation switching during the driving of the sheet piles 1. The moving track 2 is laid parallel to the driving trajectory of the sheet piles 1 on the bank, providing a horizontal reference for the support frame 3 and ensuring positional accuracy during workstation switching. The traction unit 5 uses a winch 502 to tension the wire rope 503, adjusting the inclination of the top of the sheet piles 1, and working in conjunction with the guide assembly 4 to improve verticality control. This device, through its modular structural design, balances stability and flexibility, significantly reducing adjustment workload and improving construction efficiency. It reduces the frequency of length adjustments for the hydraulic cylinder 401, retaining the length positioning foundation of the previous set of driven sheet piles 1 when moving adjacent sheet piles 1, enabling smooth transfer between workstations and solving the drawback of traditional support mechanisms requiring readjustment for each new sheet pile 1 alignment.

[0021] The sliding connection between the moving track 2 and the support frame 3 is to enable the overall horizontal switching of the device, avoiding the problem of losing the reference point when the device moves as a whole, and ensuring that it can maintain parallelism with the driving trajectory of the sheet pile 1 after each position transfer. Three sets of guide components 4 correspond to the upper and lower parts of the newly driven sheet pile 1 and the middle part of the already driven sheet pile, respectively, and can limit the sheet pile 1 from three heights to prevent deviation during driving. Each set of guide components 4 uses two parallel hydraulic cylinders 401, in conjunction with the top roller 402. The hydraulic cylinders 401 can extend and retract to adapt to the surface of sheet piles of different thicknesses or uneven structures, while the rotation of the rollers 402 reduces friction with the surface of the sheet pile 1, preventing damage to the sheet pile 1 without affecting the driving process. The tensioning unit 5 precisely adjusts the inclination of the top of the sheet pile 1 by tensioning it, which is particularly suitable for construction scenarios with many interference factors such as wind and water flow in water-adjacent land areas, improving the accuracy of verticality control.

[0022] In the preferred embodiment, the rear ends of the three sets of guide components 4 are connected to the three vertices of the rotating frame 6 of the equilateral triangle structure, which is used to switch the contact position of the guide components 4 by rotating the rotating frame 6. The front end of the support frame 3 is provided with two vertical and parallel guide frames 7. Multiple horizontal bars 8 are provided horizontally and parallel between the guide frames 7. The horizontal bars 8 include a first horizontal bar 801, a second horizontal bar 802 and a third horizontal bar 803. The rear ends of the three sets of guide components 4 pass through the rotating frame 6 and are fixed on the first horizontal bar 801, the second horizontal bar 802 and the third horizontal bar 803 respectively, for adjusting the abutment height of the guide components 4.

[0023] An equilateral triangle rotating frame 6 connects three sets of guide components 4 to its three vertices. The core purpose is to enable the orientation switching of the guide components 4 while retaining the length positioning basis of the previous set of insertions. The equilateral triangle structure features high stability and uniform spacing between vertices. Its three vertices precisely correspond to the three abutment heights of the three sets of guide components 4. A 120-degree rotation completes the orientation switching of the three sets of guide components 4 without needing to readjust the length of all hydraulic cylinders 401. The two vertical guide frames 7 and three horizontal bars 8 provide stable support for the guide components 4. Adjusting the height of the horizontal bars 8 accommodates the overall height shift after the rotating frame 6 rotates. The three horizontal bars 8 correspond to the three sets of guide components 4, ensuring each set has an independent support structure, preventing structural deformation due to excessive force on a single horizontal bar, and providing redundant space for height adjustment of the guide components 4 to meet the height compensation requirements after rotation.

[0024] In the preferred embodiment, the rear ends of the two hydraulic cylinders 401 of each guide assembly 4 are fixedly connected to both ends of the connecting plate 403, and a rotating drum 404 is provided in the middle of the rear end of the connecting plate 403; Rotating sleeves 601 are provided at each of the three vertices of the rotating frame 6. The rotating cylinder 404 is fitted inside the rotating sleeves 601 to realize the rotational connection between the guide component 4 and the rotating frame 6. The rotating sleeve 601 has an annular groove 6011 in the middle, and the rotating cylinder 404 has a convex ring 4041 in the middle that matches the annular groove 6011. Through the cooperation of the annular groove 6011 and the convex ring 4041, the axial positioning of the guide component 4 and the rotating frame 6 is achieved.

[0025] The cooperation between the rotating drum 404 and the rotating sleeve 601 is to achieve the rotational connection between the guide assembly 4 and the rotating frame 6. Simultaneously, the annular groove 6011 and the grooved ring of the convex ring 4041 engage to achieve axial limiting, preventing axial displacement or detachment of the guide assembly 4 during rotation or under stress. The connecting plate 403 fixes the two hydraulic cylinders 401 into one unit, ensuring synchronous operation of the two sets of hydraulic cylinders 401 and preventing a decrease in guiding accuracy due to misalignment of a single set of hydraulic cylinders 401. It also provides a mounting carrier for the rotating drum 404, achieving a stable connection between the guide assembly 4 and the rotating frame 6, ensuring that the rotating frame 6 can synchronously drive the guide assembly 4 to switch positions when rotating.

[0026] In the preferred embodiment, a rotating rod 9 is also provided on the rear side of the guide assembly 4. A positioning key 901 is provided on the top circumference of the rotating rod 9. A positioning groove 4042 adapted to the positioning key 901 is provided on the inner wall of the rotating cylinder 404. The rotating rod 9 drives the guide assembly 4 to rotate around the rotation axis of the rotating sleeve 601 through the keyway cooperation between the positioning key 901 and the positioning groove 4042, which is used to adjust the angle of the guide assembly 4.

[0027] The keyway between the rotating rod 9 and the positioning key 901 and the positioning groove 4042 is designed to address the issue of angular displacement of the guide component 4 after the rotating frame 6 rotates. When the rotating frame 6 rotates 120 degrees, the guide component 4 rotates synchronously, causing the hydraulic cylinder 401 to lose its horizontal contact position. The rotating rod 9 drives the guide component 4 to rotate around the axis of the rotating sleeve 601, adjusting the angle of the guide component 4 and restoring the two hydraulic cylinders 401 to a horizontal state, ensuring accurate contact with the surface of the sheet pile 1. The keyway connection provides precise positioning and reliable transmission, enabling rapid angular positioning of the guide component 4, preventing angular deviations from affecting the contact effect, simplifying the angle adjustment process, and improving construction efficiency.

[0028] In the preferred embodiment, the crossbar 8 has an elongated hole 804 that matches the diameter of the rotating rod 9 along its length. The two ends and the end of the elongated hole 804 are provided with slots 805. The rear end of the rotating rod 9 slides along the elongated hole 804 and is inserted into the slots 805 to achieve positioning. The rear end of the rotating rod 9 is provided with an external thread 902, and the front and rear sides of the crossbar 8 are provided with locking nuts 10. The two locking nuts 10 are threadedly connected to the external thread 902 at the rear end of the rotating rod 9, and are used to lock the angle and position of the rotating rod 9 by clamping the crossbar 8.

[0029] The elongated hole 804 and the slot 805 are designed to accommodate the position adjustment and positioning requirements of the guide assembly 4. The elongated hole 804 allows the rotating rod 9 to slide along the length of the crossbar 8, providing space for the rotation of the rotating frame 6 and the switching of work positions. The slot 805 is located at both ends and the midpoint of the elongated hole 804, enabling precise positioning of the rotating rod 9, preventing the guide assembly 4 from sliding during construction, and ensuring stable contact. The locking nut 10 clamps the crossbar 8 to fix the position and angle of the rotating rod 9. The locking method on both sides not only locks the axial position of the rotating rod 9, preventing the rotating rod 9 from moving when the hydraulic cylinder 401 extends or retracts, but also locks the rotation angle of the rotating rod 9, ensuring that the guide assembly 4 maintains the preset contact posture. The rotating rod 9 can be pulled out by loosening only the front locking nut, while the rear locking nut remains stationary, preserving the length positioning basis of the rotating rod 9 and further reducing the amount of adjustment work.

[0030] In the preferred embodiment, the length of the oblong hole 804 is twice the height of the equilateral triangle of the rotating frame 6.

[0031] The length of the oblong hole 804 is set to twice the height of the equilateral triangle of the rotating frame 6, which is designed based on the rotation and position switching requirements of the guide component 4. The height of the equilateral triangle matches the shortest distance between the vertical axes of symmetry of the two interlocking sheet piles 1. Setting the length of the oblong hole 804 to twice this height ensures that after the guide component 4 rotates 120 degrees, the rotating rod 9 can complete the position switching within the oblong hole 804, while providing sufficient space for the relative sliding of the support frame 3 and the rotating frame 6, avoiding structural interference. This length design balances the position adjustment range and structural compactness, meeting the maneuvering requirements without causing a decrease in the positioning accuracy of the rotating rod 9 due to an excessively long oblong hole 804.

[0032] In the preferred embodiment, four sets of pins 11 are symmetrically arranged on the guide frame 7. The pins 11 pass through the guide frame 7 and are inserted into the crossbar 8 to fix the relative height of the crossbar 8. The heights corresponding to the four sets of pins 11 are respectively the upper abutment height of the newly driven steel sheet pile 1, the lower abutment height of the newly driven steel sheet pile 1, the middle abutment height of the adjacent driven steel sheet pile 1, and the reserved height that is lower than the lower abutment height of the newly driven steel sheet pile 1 and the spacing is half the side length of the equilateral triangle of the rotating frame 6.

[0033] The four sets of pins 11 are used to adjust the height of the crossbar 8, solving the problem of the rotating frame 6 shifting downwards by half the side length of an equilateral triangle after rotation. The four sets of pins 11 correspond to three working heights and one reserved height. By adjusting the installation height of the crossbar 8, the height offset of the rotating frame 6 can be compensated, ensuring that the guide component 4 always accurately abuts against the preset height position of the sheet pile 1. The reserved height is lower than the lower abutment height of the newly driven sheet pile by half the side length of an equilateral triangle, providing redundancy for the height adjustment of the crossbar 8. This accommodates the orientation switching and height compensation requirements of the guide component 4 during continuous construction, ensuring the continuous and stable operation of the device. The pins 11 are symmetrically arranged on the guide frame 7 to stably fix the crossbar 8, preventing it from swaying during construction and improving the overall structural stability.

[0034] In the preferred embodiment, the winch 502 is equipped with a meter counter 504 and a tension sensor 505 to detect the pulling length and tension of the wire rope 503.

[0035] The meter counter 504 detects the length of the wire rope 503 during both release and retraction, thereby limiting the displacement of the top of the sheet pile 1 and preventing excessive tension that could lead to deformation or excessive tilting of the sheet pile 1. The tension sensor 505 monitors the tension force in real time, preventing damage to the sheet pile 1 due to excessive tension or insufficient tension that would prevent effective adjustment of verticality. Together with the PLC control system, these two components enable automated control of the wire rope 503 pulling process, reducing human error, improving the consistency and accuracy of verticality control, and meeting the needs of large-scale, high-standard sheet pile driving construction.

[0036] Example 2 Further explanation in conjunction with Example 1, such as Figure 1-11 The structure shown illustrates a construction method for a steel sheet pile verticality control device in a water-adjacent land area. The method includes: S1. Level the construction site, complete the survey and layout according to the steel sheet pile construction line, and determine the driving trajectory of steel sheet pile 1 and the laying position of moving track 2. S2. Lay the moving track 2 according to the layout position, level and calibrate the moving track 2, and after the levelness and straightness meet the standards, install the support frame 3 onto the moving track 2. S3. Drive a steel sheet pile horizontally at the construction position of the first steel sheet pile 1 as a positioning guide pile. Weld a lifting ring to the top of the positioning guide pile, and tie the steel wire rope 503 to the positioning guide pile through the lifting ring. Use a vibratory hammer to drive the first steel sheet pile 1 to the preset depth. S4. Install guide component 4 at the corresponding midpoint of the first steel sheet pile 1 that has been driven into place, and adjust the length of hydraulic cylinder 401 so that the roller 402 at the front end of guide component 4 is tangentially attached to the surface of the first steel sheet pile 1. S5. Start the winch 502 to tighten the wire rope 503 connecting the first sheet pile, and adjust the inclination of the top of the sheet pile 1 to ensure that its verticality meets the standard. S6. Hoist the second sheet pile 1 and insert it into the soil along the locking mechanism of the first sheet pile 1. When the insertion depth reaches about 1m, install the guide components 4 corresponding to the upper and lower abutment heights. After fixing, adjust the length of the hydraulic cylinder 401 so that the roller 402 is tangentially attached to the surface of the second sheet pile 1. Use a vibratory hammer to drive the second sheet pile 1 to the design depth. S7. Hoist the third sheet pile 1 and insert it into the soil along the locking mechanism of the second sheet pile 1. When the insertion depth reaches about 1m, rotate the rotating frame 6 and adjust the height of the crossbar 8. Switch each set of guide components 4 to the next set of abutment positions and adjust the length of the hydraulic cylinder 401. Move the support frame 3 forward one construction position along the moving track 2. Tighten the wire rope 503 through the winch 502 to adjust the inclination of the top of the sheet pile 1. S8. Repeat step S7 to continue moving forward and completing the subsequent steel sheet pile 1 driving operation until the overall construction is completed.

[0037] In the preferred embodiment, step S7 includes: S71. Loosen the locking nut 10 on the side of the three sets of guide components 4 closest to the steel sheet pile 1, and pull back the rotating rod 9 with the upper and middle abutment heights, so that the positioning key 901 is disengaged from the keyway of the positioning groove 4042 on the inner wall of the rotating cylinder 404.

[0038] This embodiment, based on the device described in Embodiment 1, provides a construction method for controlling the verticality of sheet piles in water-adjacent land areas. The core logic relies on the rotating and height-adjusting structures of the device to achieve rapid orientation switching and workstation transfer of the guide component 4, preserving the length positioning foundation, reducing the workload of adjusting the hydraulic cylinders 401, and improving construction efficiency and verticality control accuracy. This method eliminates the need to readjust the length of all hydraulic cylinders 401 in the guide component 4 for each new sheet pile alignment; only one set of hydraulic cylinders 4 needs to be adjusted to complete the workstation switching and guiding positioning, significantly simplifying the construction process. It is particularly suitable for continuous sheet pile driving construction in water-adjacent land areas.

[0039] During construction, precise construction benchmarks are first established through surveying and track installation to ensure that the driving alignment of the sheet pile 1 meets design requirements. The first sheet pile serves as a positioning guide pile, positioned by the guide assembly 4 and tensioned by the winch 502, laying the verticality benchmark for subsequent construction. During subsequent sheet pile driving, the 120-degree rotation of the rotating frame 6 completes the orientation switching of the three sets of guide assemblies 4, transferring the hydraulic cylinder 401, which is adapted to the concave and convex structure of the sheet pile, to the new contact position, preserving the length positioning foundation. The height adjustment of the crossbar 8 compensates for the height deviation of the rotating frame 6, ensuring precise contact of the guide assembly 4. The support frame 3 slides along the moving track 2 to achieve overall work position switching, cooperating with the guide assembly 4 and the tensioning unit 5 to complete the verticality control and driving of the new sheet pile.

[0040] The specific steps for the orientation switching, height adjustment, and workstation transfer of the guide component 4 are as follows: To ensure smooth connection and accurate positioning of each step, first loosen the front locking nut 10 and pull out the rotating rod 9 to provide space for the rotation of the rotating frame 6. Simultaneously, the lower guide component 4, which remains connected, provides support to prevent structural loosening. After the rotating frame 6 rotates, reposition the rotating rod 9 and adjust the angle of the guide component 4 to ensure that the hydraulic cylinder 401 is horizontally supported. Only one set of hydraulic cylinders 401 is adjusted to minimize the adjustment workload. The height deviation is compensated by adjusting the position of the crossbar 8 and moving it upwards as a whole. Finally, the workstation is locked and the wire rope 503 is tensioned to ensure the verticality stability during the driving of the new sheet piles. The entire construction process, relying on the structural design of the device, achieves continuous and efficient construction, balancing construction accuracy and efficiency, and solving the problems of cumbersome adjustments and easy loss of reference points in traditional construction.
