Description

Technical Field

[0001] This invention relates to the field of waterway engineering technology, specifically to a vibratory piling device for ultra-long steel sheet piles in inland waterways. Background Technology

[0002] The vibratory pile driving device for ultra-long steel sheet piles in inland waterways is a highly efficient construction equipment specifically designed for the construction and maintenance of inland waterways. It is primarily used to quickly and accurately drive ultra-long steel sheet piles underwater or into the riverbank soil to form a stable support structure. The device generates vertical excitation force through a high-frequency hydraulic or electric vibratory hammer, causing the pile to resonate with the surrounding soil. Under high-frequency vibration, the soil liquefies, significantly reducing frictional resistance. Combined with the weight of the pile driver and the downward pressure from the excavator, this enables the rapid sinking of the steel sheet piles.

[0003] Existing vibratory pile driving devices for ultra-long steel sheet piles in inland waterways mostly adopt fixed parameter vibration modes and rely on manual judgment of stratum characteristics. This approach suffers from multiple technical drawbacks. Its core operation process depends on manual inspection to determine soil compaction and pile tilt status. Subsequently, construction resistance is addressed by manually adjusting the vibration frequency and changing auxiliary tools. This manual operation has significant judgment lag and parameter errors, making it difficult to accurately match the vibration energy output with the actual stratum resistance. Furthermore, insufficient excitation force often leads to pile driving stagnation, and pile bending caused by stress imbalance in the anti-tilt structure. At the same time, traditional fixed-amplitude rigid vibration systems cannot adapt to the nonlinear load disturbances generated by geological stratification and water flow velocity, resulting in redundant waste of vibration energy in soft soil strata and rapid wear of wear-resistant components in hard rock strata. This leads to a sharp drop in equipment operating efficiency, stress concentration in key components, and excessive pile verticality. In addition, emergency handling of existing solutions requires external lifting equipment or shutdown for adjustment. This not only fails to utilize the device's own dynamic characteristics to quickly overcome resistance but also increases construction costs due to the excessively long fault handling cycle caused by external reliance.

[0004] Therefore, we propose a vibratory piling device for ultra-long steel sheet piles in inland waterways to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a vibratory pile driving device for ultra-long steel sheet piles in inland waterways. By leveraging the synergistic effect of physical disturbance components and gas-liquid energy regulation components, it achieves efficient and precise pile driving of ultra-long steel sheet piles in inland waterways.

Moreover, the active effect of gas-liquid energy significantly reduces the direct friction between the pile and the soil, reduces the wear rate of wear-resistant components, and extends the replacement cycle of core components.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-3 As shown, this embodiment discloses a vibratory pile driving device for ultra-long steel sheet piles in inland waterways, a pile hammer 100, and a steel sheet pile 400, a physical disturbance component 500, and a gas-liquid energy control component 600 respectively provided at the bottom of the pile hammer 100. The gas-liquid energy control component 600 is installed on one side of the outer wall of the physical disturbance component 500. like Figure 5 as well as Figure 7As shown, the gas-liquid energy regulation component 600 includes an annular gas pipe 606, an annular liquid pipe 608, two sets of Venturi tubes 609, and two sets of piezoelectric ceramic groups 611. The annular gas pipe 606 is used to output high-pressure gas, the annular liquid pipe 608 is used to transport high-pressure liquid, the two sets of Venturi tubes 609 are used to form a high-speed water jet using the Venturi effect, and the two sets of piezoelectric ceramic groups 611 are used to generate high-frequency vibration. like Figure 10 as well as Figure 12 As shown, the physical disturbance component 500 includes four high-frequency acoustic wave generators 504, four soil resistance monitoring probes 508, a set of corrugated pipes 515, and a set of nickel-chromium alloy heating wires 516. The four high-frequency acoustic wave generators 504 are used to output high-frequency mechanical vibrations, the four soil resistance monitoring probes 508 are used to collect the side friction resistance of the soil around the steel sheet pile in real time, the set of corrugated pipes 515 are used to provide flexible buffering, and the set of nickel-chromium alloy heating wires 516 are used to dynamically control the temperature of the set of corrugated pipes 515.

[0021] This embodiment primarily addresses the issue that existing 400mm vibratory pile driving devices for ultra-long steel sheet piles in inland waterways mostly employ fixed-parameter vibration modes and rely on manual assessment of soil characteristics. This approach suffers from multiple technical drawbacks. Its core operational process depends on manual inspection to determine soil compaction and pile tilt, followed by manual adjustment of the vibration frequency and replacement of auxiliary tools to address construction resistance. This manual operation suffers from significant judgment lag and parameter errors, making it difficult to accurately match the vibration energy output with the actual soil resistance. Furthermore, insufficient excitation force often leads to pile driving stagnation, and the anti-tilt structure... The steel sheet piles bend by 400 degrees due to stress imbalance. At the same time, the traditional fixed amplitude rigid vibration system cannot adapt to the nonlinear load disturbances caused by geological stratification and water flow velocity. This leads to redundant waste of vibration energy under soft soil strata and rapid wear of wear-resistant components under hard rock strata. As a result, the equipment operating efficiency drops sharply, stress concentration of key components and pile verticality exceeds the standard. Secondly, the emergency handling of existing solutions requires external lifting equipment or shutdown for adjustment. It is impossible to use the device's own dynamic characteristics to achieve rapid resistance breakthrough. Furthermore, the external dependence leads to an excessively long fault handling cycle, which increases construction costs.

[0022] This embodiment addresses the problems of existing technologies by leveraging the synergistic effect of the physical disturbance component 500 and the gas-liquid energy regulation component 600 to achieve efficient and precise pile driving of ultra-long steel sheet piles 400 in inland waterways. Unlike traditional passive and inefficient methods that rely on manual judgment of soil characteristics and fixed vibration parameters, this embodiment makes pile driving operations more stable and reliable. Firstly, by utilizing the linkage between the high-frequency acoustic generator 504 and the soil resistance monitoring probe 508, combined with the flexible adaptation of the corrugated pipe 515, it can both pre-disturb the soil around the pile through high-frequency vibration to reduce pile driving resistance, and also adjust the pile driving process according to... The dynamic adjustment of the micro hydraulic actuator 513 and ball joint 514 corrects the posture of the sheet pile 400 in real time, avoiding bending of the sheet pile 400 caused by rigid collision. At the same time, the three-layer nested nozzle, annular air pipe 606 and annular liquid pipe 608 of the gas-liquid energy regulation component 600 break through the limitations of traditional fixed energy output, allowing the high-pressure jet and air film isolation to reach the key area around the sheet pile 400, accurately matching the needs of all strata from soft soil to hard rock. Moreover, the active action of gas-liquid energy greatly reduces the direct friction between the sheet pile 400 and the soil, reducing the wear rate of wear-resistant components.

[0023] according to Figures 1-3 As shown, a clamping assembly 200 is installed at the bottom of the pile hammer 100, and the sheet pile 400 is clamped between the outer walls of the clamping assembly 200. Four support columns 300 are connected to the bottom of the pile hammer 100.

[0024] In this embodiment of the invention, the clamping component 200 firstly restricts the lateral sway of the sheet pile 400 during vibratory pile driving by clamping the sheet pile 400 against the outer wall of the sheet pile 400, ensuring that the vertical excitation force of the pile hammer 100 is accurately applied to the sheet pile 400, thereby reducing energy loss. The four support columns 300 are vertically connected to the bottom of the pile hammer 100, providing a stable mounting carrier for the physical disturbance component 500 and the gas-liquid energy regulation component 600, and also preventing the components from loosening due to vibration by distributing the force, so that the entire device maintains structural stability during high-intensity operation.

[0025] according to Figure 4 As shown, the gas-liquid energy regulation component 600 also includes a high-pressure solenoid valve 601. The high-pressure solenoid valve 601 is a three-position four-way high-pressure solenoid valve 601, and the high-pressure solenoid valve 601 is used to control the on / off state and ratio of the gas source and the liquid source. The gas outlet and liquid outlet of the three-position four-way high-pressure solenoid valve 601 are respectively connected to a first connecting pipe 602 and a second connecting pipe 604. The gas outlet of the first connecting pipe 602 is connected to an air inlet pipe 603.

[0026] In this embodiment of the invention, the three-position four-way high-pressure solenoid valve 601 firstly uses the soil resistance monitoring data to switch the supply status of the gas source and liquid source in real time. When encountering soft soil, the gas output ratio is increased to reduce drag by gas film. When encountering hard layers, the liquid supply is increased to fully break up the soil using high-pressure jet. This solves the problem that the traditional fixed gas-liquid ratio cannot be adapted to complex strata. The first connecting pipe 602, the second connecting pipe 604, and the air inlet pipe 603 can ensure that there is no leakage in the transmission of high-pressure gas and liquid, allowing the gas and liquid energy to be efficiently transferred to the subsequent components.

[0027] according to Figure 5 As shown, the air outlet of the air inlet pipe 603 is connected to the air inlet of the annular air pipe 606. The liquid outlet of the second connecting pipe 604 is connected to the liquid inlet pipe 605. The liquid outlet of the liquid inlet pipe 605 is connected to the liquid inlet of the annular liquid pipe 608. A set of fixing posts 607 are connected to the top of the annular liquid pipe 608, and the top of the set of fixing posts 607 is connected to the top of the inner wall of the annular air pipe 606.

[0028] In this embodiment of the invention, the air inlet pipe 603 and the liquid inlet pipe 605 first precisely introduce high-pressure gas and liquid into the annular air pipe 606 and the annular liquid pipe 608, respectively, so that the gas and liquid can be evenly distributed along the annular air pipe 606 and the annular liquid pipe 608. The fixed column 607 firmly connects the annular air pipe 606 and the annular liquid pipe 608 into a whole, avoiding misalignment or separation of the pipes during vibration operation. This effectively ensures that the gas and liquid can act synchronously around the steel sheet pile 400, without local energy deficiency, and enhances the device's ability to process the entire surrounding strata.

[0029] according to Figures 6-7 As shown, the bottom and outer surface of the annular gas pipe 606 and the annular liquid pipe 608 are provided with a set of gas outlet holes and a set of liquid outlet holes. The liquid outlet ends of the two sets of liquid outlet holes are connected to the liquid inlet ends of the corresponding set of Venturi tubes 609. The inner surfaces of the two sets of Venturi tubes 609 are connected to a resonant cavity 610. The two sets of resonant cavities 610 cover the outer surfaces of the two sets of piezoelectric ceramic groups 611. The gas outlet ends of the two sets of gas outlet holes are connected to a gas outlet pipe 612. The inner surfaces of the two sets of gas outlet pipes 612 are connected to a nozzle 613.

[0030] In this embodiment of the invention, the air outlet and liquid outlet on the annular air pipe 606 and the annular liquid pipe 608 are uniformly distributed circumferentially, allowing the gas and liquid to act on the strata around the sheet pile 400 without dead angles. The Venturi tube 609 can further increase the liquid flow velocity. Combined with the high-frequency vibration transmitted by the piezoelectric ceramic assembly 611 through the resonant cavity 610, the jet has both high-speed impact and pulse oscillation, thus easily breaking hard rock or gravel. The high-pressure gas ejected from the nozzle 613 forms an annular gas film, separating the sheet pile 400 from the soil and reducing direct friction, thus solving the problem of low efficiency of traditional single vibration or jet in complex strata.

[0031] according to Figure 9 As shown, the physical disturbance component 500 also includes four electric cylinders 501, and the four electric cylinders 501 are installed at the bottom of the four support columns 300. The shaft ends of the four electric cylinders 501 are all fitted with connecting plates 502. One end of the outer wall of the four connecting plates 502 is connected to a telescopic frame 503, and the top fixed end of the four telescopic frames 503 is connected to the bottom of the four support columns 300.

[0032] In this embodiment of the invention, the electric cylinder 501 first drives the telescopic frame 503 to extend and retract up and down through the connecting plate 502. It can adjust the height of the physical disturbance component 500 and the gas-liquid energy regulation component 600 in real time according to the sinking depth of the steel sheet pile 400, ensuring that the physical disturbance effect always covers the key area where the steel sheet pile 400 contacts the ground. The fixed connection between the telescopic frame 503 and the support column 300 ensures the structural rigidity, and it will not deform even under high frequency vibration, making the installation and operation of subsequent components more stable.

[0033] according to Figure 10 As shown, each of the four telescopic frames 503 is connected to a corresponding high-frequency sound wave generator 504 on one side of its opposite side. The outer walls of the four telescopic frames 503 are connected to the outer surface of the annular air pipe 606. Each of the four telescopic frames 503 is bolted to a flange 505 on one side of its opposite side. Each of the four flanges 505 is equipped with a hydraulic cylinder 506 on one side of its outer wall.

[0034] In this embodiment of the invention, firstly, the high-frequency acoustic generator 504 is fixed inside the telescopic frame 503, which can directly emit high-frequency vibrations to the soil around the sheet pile 400, loosening the soil structure in advance and reducing the resistance of pile driving. Secondly, the flange 505 is connected to the hydraulic cylinder 506 by bolts, which is not only firmly connected, but also only requires disassembling the bolts for later maintenance and replacement, which is more convenient than the traditional welding method. The hydraulic cylinder 506 can flexibly adjust the thrust according to the soil resistance, which can ensure the stable clamping of the sheet pile 400 without causing the pile to deform due to excessive force.

[0035] according to Figure 10As shown, wear-resistant buffer blocks 507 are fitted on the shaft ends of the four hydraulic cylinders 506. The four wear-resistant buffer blocks 507 are made of high wear-resistant rubber material, and the four wear-resistant buffer blocks 507 are used to provide elastic deformation. One end of the outer wall of the four wear-resistant buffer blocks 507 is connected to one side of the outer wall of a corresponding soil resistance monitoring probe 508.

[0036] In this embodiment of the invention, a wear-resistant buffer block 507 made of high wear-resistant rubber material is first used to directly contact the steel sheet pile 400. This block can withstand long-term friction without being easily damaged, and can effectively absorb vibration impact through elastic deformation, thus avoiding damage caused by hard collision between the hydraulic cylinder 506 and the steel sheet pile 400. The soil resistance monitoring probe 508 is attached to the wear-resistant buffer block 507, which can sense the resistance changes in different directions around the steel sheet pile 400 in real time and transmit the data to the control system. This provides a basis for subsequent energy regulation and attitude correction, solving the problem of lag in traditional manual judgment.

[0037] according to Figures 10-11 As shown, each of the four telescopic frames 503 has a sliding groove 509 on one side of its opposite side. The inner walls of the four sliding grooves 509 are slidably connected to a slide plate 510. The four slide plates 510 are connected to a ring frame 511. The inner surface of the ring frame 511 has a set of mounting plates 512 arranged in a ring. One end of the outer wall of each set of mounting plates 512 is connected to a micro hydraulic actuator 513, and the set of micro hydraulic actuators 513 are all used to provide telescopic movement.

[0038] In this embodiment of the invention, the sliding engagement of the slide groove 509 and the slide plate 510 allows the ring frame 511 to sink synchronously with the sheet pile 400, ensuring that the corrugated pipe 515 always maintains effective contact with the sheet pile 400. The micro hydraulic actuator 513 on the ring frame 511 is fixed by the mounting plate 512 and can perform fine extension and retraction according to the monitoring data, applying corrective force to the sheet pile 400 from multiple directions, adjusting the verticality of the sheet pile 400 in a timely manner, and avoiding the deflection problem caused by traditional rigid guides.

[0039] according to Figure 12 As shown, the shaft ends of a set of miniature hydraulic actuators 513 are all connected to ball joints 514, and the set of ball joints 514 are all used for multi-angle rotation. One end of the outer wall of the set of ball joints 514 is connected to a set of bellows 515. The outer surface of the set of bellows 515 is all wound and connected to a set of nickel-chromium alloy heating wires 516. One end of the outer wall of the set of bellows 515 is connected to a soft contact 517.

[0040] In this embodiment of the invention, firstly, the ball joint 514 can adapt to the corrugated pipe 515 at multiple angles, which can adapt to the slight tilt of the sheet pile 400 and prevent the components from being damaged due to uneven force. Secondly, the corrugated pipe 515 itself is elastic, which can buffer vibration and provide flexible support. With the externally wrapped nickel-chromium alloy heating wire 516, it can be heated and kept warm in low-temperature environments to ensure that its elasticity is not affected by freezing. Furthermore, the soft contact part 517 is directly attached to the sheet pile 400, which can adapt to sheet piles 400 with different cross-sectional shapes and avoid scratching the surface of the sheet pile 400, making the posture correction safer and more reliable.

[0041] During use, the entire physical disturbance component 500 and the gas-liquid energy regulation component 600 work together to ensure the stable progress of the pile driving process. After the entire device is started, four electric cylinders 501 drive the telescopic frame 503 downward through the connecting plate 502, lowering the entire component to a position where it is about to contact the soil around the sheet pile 400. Then, the physical disturbance component 500 is pre-activated, and four high-frequency sound wave generators 504 start working, emitting high-frequency mechanical vibrations to the sheet pile 400. This causes the sheet pile 400 to act on the surrounding soil, thereby pre-loosening the soil structure and significantly reducing the initial pile driving resistance. During this process, four soil resistance monitoring probes 508 continuously sense and collect data from the sheet pile 400 through the wear-resistant buffer block 507 connected to them. The data on the side friction resistance generated by the contact between the sidewall of pile 400 and the soil is transmitted in real time to the central control system. Based on this feedback, the central control system makes decisions regarding the output parameters of the gas-liquid energy regulation component 600. The control system then issues a command to the three-position four-way high-pressure solenoid valve 601. At this time, the three-position four-way high-pressure solenoid valve 601 dynamically adjusts the output ratio and on / off state of high-pressure gas and liquid according to the current soil resistance characteristics. When the soil resistance monitoring probe 508 detects low resistance and encounters a soft soil layer, the control system commands an increase in the output ratio of high-pressure gas. The high-pressure gas enters the annular gas pipe 606 through the first connecting pipe 602 and the inlet pipe 603, and is finally ejected through the nozzle 613, forming a layer around the sheet pile 400. The annular air film acts as an isolation and lubricant, greatly reducing the direct friction between the sheet pile 400 and the soil. When the soil resistance monitoring probe 508 detects a sharp increase in resistance, i.e., encountering hard rock or a dense layer, the control system will issue a command to increase the output ratio of the high-pressure liquid. At this time, the high-pressure liquid is pumped into the annular liquid pipe 608 through the second connecting pipe 604 and the inlet pipe 605, and enters the Venturi tube 609 through the outlet hole at its bottom. At this time, the liquid is accelerated into a high-speed jet by utilizing the Venturi effect. At the same time, the high-frequency vibration energy generated by the piezoelectric ceramic assembly 611 in the resonant cavity 610 is coupled into the jet, forming a pulse jet with strong impact and oscillating breaking capabilities, which directly acts on the sheet pile 400 and the hard rock surrounding the sheet pile 400. This achieves efficient crushing. Throughout the pile driving process, the attitude correction function of the physical disturbance component 500 operates synchronously. The micro hydraulic actuator 513, based on monitored pile tilt data, uses the universal adjustment characteristic of the ball joint 514 to drive the bellows 515 and soft contact element 517 to apply precise lateral corrective force to the sheet pile 400, dynamically fine-tuning the pile's attitude in real time to ensure verticality. Subsequently, the nickel-chromium alloy heating wire 516 dynamically adjusts the temperature of the bellows 515 according to the ambient temperature, ensuring excellent flexibility and buffering performance even at low temperatures, making the correction action always sensitive and effective. In summary, the physical disturbance component 500 and the gas-liquid energy control component 600 constitute an effective closed loop of perception, decision-making, and execution.The integration of three main functions—high-frequency vibration pre-disturbance, on-demand gas-liquid energy output, and real-time dynamic correction of the sheet pile's attitude—completely transforms the traditional piling equipment's reliance on fixed parameters and manual intervention. This achieves a high degree of adaptability to complex geological conditions, ultimately ensuring the efficient and precise driving of the ultra-long sheet pile into its predetermined position.
