Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, and is particularly aimed at complex working conditions such as a large amount of backfill soil, high water content silt and narrow working area in the process of rapid sealing of dike breaches. Specifically, it relates to a hydraulic rapid compaction device suitable for soft foundation reinforcement in the process of sealing dike breaches. Background Technology

[0002] my country has numerous rivers and lakes, and a vast system of dikes. Due to extreme weather, sustained high water levels, and geological conditions, dike breaches occur frequently during the annual flood season. Breach repair is extremely time-sensitive and dangerous, requiring the rapid restoration of the dike structure and reinforcement of soft soil foundations to prevent further damage and minimize losses. Therefore, developing efficient, mobile, and adaptable rapid reinforcement equipment is of great practical significance for improving flood control and emergency response capabilities and protecting people's lives and property.

[0003] Currently, the main traditional compaction equipment for soft foundation reinforcement includes vibratory rollers, hydraulic rammers, and dynamic compaction machines, all of which have significant limitations in emergency situations such as sealing breaches in dikes.

[0004] Although vibratory rollers are suitable for large-area compaction, their equipment is bulky and has poor mobility, making it difficult to enter narrow areas of the breach. Their vibration compaction effect is mainly concentrated in the shallow surface layer, and their effect on reinforcing deep soft soil foundations with high water content is limited. At the same time, continuous vibration can easily disturb the already initially stabilized backfill and surrounding structures, which may exacerbate the risk of seepage, contradicting the fundamental goal of "rapid stabilization" in emergency rescue operations.

[0005] While existing hydraulic compactors possess a certain degree of mobility and impact capability, they are suitable for small-scale, shallow-to-medium-level compaction scenarios such as foundation reinforcement and backfilling of abutments. They are ill-suited for the soft ground reinforcement and compaction of backfill soil during the process of sealing dike breaches.

[0006] Dynamic compaction machines rely on huge impact energy to achieve deep reinforcement, but their equipment is large, has high requirements for operating radius, and poor mobility. They are completely unable to adapt to complex terrains such as narrow breaches, water, and slopes. The huge impact energy can easily damage the initial structure of the filled body, and even induce secondary landslides or seepage damage. The safety risks are high and are seriously inconsistent with the principles of rapid, precise, and low-disturbance emergency rescue operations.

[0007] In summary, existing compaction equipment faces common problems in dealing with dike breaches, including "inability to enter, inadequate compaction, lack of control, and low efficiency." The special conditions of narrow breach working areas, soft and wet soil, and tight deadlines require equipment to simultaneously possess: good terrain mobility and adaptability to confined spaces; precise adjustment of impact energy to balance surface compaction and deep reinforcement; rapid and continuous operation capability to reduce equipment relocation and adjustment time; and minimal disturbance to the existing fill structure to avoid secondary hazards.

[0008] Therefore, developing a specialized hydraulic rapid compaction device that integrates rapid mobility, precise control, deep efficiency, and low disturbance has become an urgent need to improve the technical level of dike breach repair. Against this backdrop, this invention addresses the shortcomings of existing equipment and the needs of practical emergency repairs by proposing a hydraulic rapid compaction device suitable for soft soil foundation reinforcement during dike breach sealing. Summary of the Invention

[0009] The purpose of this invention is to address the technical bottlenecks in soft ground foundation reinforcement during dike breach emergency repairs by providing a hydraulic rapid compaction device that can adapt to narrow working spaces, achieve precise control of impact energy, balance surface compaction and deep reinforcement, operate continuously and efficiently, and cause minimal disturbance to the already filled structure. This solves the prominent problems of traditional compaction equipment in breach emergency repair scenarios, such as "inability to enter, inadequate compaction, lack of control, and low efficiency."

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hydraulic rapid compaction device suitable for soft ground reinforcement during the process of sealing dike breaches, including a skid steer loader body 1, a quick-change device 5, a connecting frame 8, a compaction mechanism 9, and an operation posture control system; The quick-change device 5 is installed at the front end of the boom 3 of the skid steer loader body 1; The compaction mechanism 9 slides with the connecting frame slide 19 of the connecting frame 8 via the tamping frame slide 14. The rear end of the connecting frame 8 is matched and connected with the quick-change device 5, so as to realize the quick assembly, disassembly and fixation of the compaction mechanism 9 and the skid steer loader body 1. The compaction mechanism 9 includes a high-speed hydraulic cylinder 10, a tamping frame 18, a hammer body 12, a tamping base 13, a hammer pad 17 and a tamping frame lifting hydraulic cylinder 11. The tail of the cylinder body of the high-speed hydraulic cylinder 10 is hinged to the first lug 21 on the top of the ramming frame 18 by a pin. The piston rod end of the high-speed hydraulic cylinder 10 is connected to the hammer body 12 by a flange, which is used to drive the hammer body 12 to move up and down reciprocally. The ramming base 13 is fastened to the lower flange of the ramming frame 18 by bolts through the upper flange of the ramming base shell 22. The hammer pad 17 is placed in the upper part of the inner cylindrical cavity of the ramming base shell 22, and the hammer body 12 is located directly above the hammer pad 17. The bottom of the ramming base shell 22 is provided with a detachable baffle 23. The lower end of the cylinder body of the ramming frame lifting cylinder 11 is hinged to the connecting seat 20 on the connecting frame 8 by a pin. The piston rod end of the ramming frame lifting cylinder 11 is connected to the second ear seat 16 at the top of the ramming frame slide 14 by a pin, which is used to drive the ramming frame 18 to rise and fall vertically along the connecting frame slide 19. The working posture control system is composed of the boom cylinder 2, bucket cylinder 4 and ramming frame lifting cylinder 1 of the skid steer loader body 1, and is used to adjust the working posture and levelness of the ramming mechanism 9.

[0011] The quick-change device 5 is equipped with a mechanical locking mechanism and a hydraulic control function. The mechanical locking mechanism includes a pin 6. By moving the quick-change handle 7 up and down, the connecting frame 8 and the boom 3 can be quickly locked and unlocked, and the hydraulic pipeline can be automatically connected at the same time.

[0012] The ramming frame 18 is a box-shaped welded structure. The ramming frame slide 14 is welded to both sides or inside the ramming frame 18 and forms a rigid whole with the ramming frame 18. The connecting frame slide 19 is welded to the connecting frame 8, and its inner cavity size is precisely matched with the ramming frame slide 14 to form a high-precision sliding pair, which restricts the ramming frame 18 to slide only in the vertical direction.

[0013] It also includes an electro-hydraulic control system, which is set in the control box. The control box is located in the skid steer loader cab or is remotely controlled. It is used to steplessly adjust the piston stroke and working frequency of the high-speed hydraulic cylinder 10, as well as control the extension and retraction of the ramming frame lifting cylinder 11.

[0014] The hammer body 12 is made of high-density metal, and the hammer pad 17 is made of high-elasticity, high-wear-resistant material, which is polyurethane or special rubber.

[0015] The inner side of the tamping frame slide 14 is welded with a limiting plate 15 to limit the maximum downward stroke of the tamping frame 18 and achieve automatic stopping of tamping at a preset depth. The welding position of the limiting plate 15 is determined according to the preset tamping depth. When the tamping frame 18 sinks to the point where the limiting plate 15 contacts the upper edge of the connecting frame slide 19, the tamping frame 18 stops sinking. At this time, the tamping frame lifting cylinder 11 reaches the lower limit of its stroke simultaneously.

[0016] The adjustment process of the working posture control system is as follows: first, fully extend the ramming frame lifting cylinder 11 to lower the ramming mechanism 9 to the lowest position; then adjust the boom cylinder 2 and the bucket cylinder 4, and finely adjust the spatial angle of the connecting frame 8 so that the bottom surface of the ramming base 13 can stably fit against the soft foundation surface.

[0017] The baffle 23 is fixed to the lower flange of the ramming base shell 22 by bolts to prevent soil from flowing into the ramming base shell 22 or the ramming base 13 from accidentally falling out during operation.

[0018] The electro-hydraulic control system can switch between impact modes. By adjusting the stroke and frequency of the high-speed hydraulic cylinder 10, it can achieve multiple compaction modes from low frequency and high energy to high frequency and medium energy, adapting to different soil types and reinforcement depth requirements.

[0019] The skid steer loader body 1 has all-wheel drive and on-the-spot steering functions, and its hydraulic output system provides power to the high-speed cylinder 10, the ramming frame lifting cylinder 11, the boom cylinder 2 and the bucket cylinder 4.

[0020] Compared with the prior art, the connection relationship and technical effects of the components of the present invention, using the above technical solution, are as follows: I. Core Load-Bearing and Power Foundation: The skid steer loader body serves as the power source, chassis, and basic control platform. Its boom is equipped with a quick-change mechanism at the front end. The boom is extended and retracted by a boom cylinder, while a bucket cylinder adjusts the boom's spatial angle. The skid steer loader body's hydraulic output system provides power to all hydraulic actuators throughout the equipment. The skid steer loader body features a compact body, all-wheel drive, and on-the-spot steering capability, ensuring flexible entry and precise positioning in narrow breaches and muddy areas.

[0021] II. Quick-Connect Mechanism: The quick-change device is a dedicated connecting component, a standard feature, equipped with an internal mechanical locking mechanism (including a pin) and hydraulic control function, precisely matching the rear structure of the connecting frame. Operators can mechanically lock / unlock the connecting frame and boom within minutes by moving the quick-change device handle up and down, simultaneously achieving automatic connection / disconnection of hydraulic lines. This allows for rapid assembly and disassembly of the compaction mechanism and the skid steer loader body, greatly improving equipment deployment speed and functional conversion flexibility.

[0022] III. Connection and Guiding Carrier: The connecting frame is a rigid connecting component, fixed to the quick-change device at the rear end, with a connecting seat welded to the rear and a connecting frame slide welded to the side. The connecting frame slide has a hollow structure, and its inner cavity size is precisely matched with the tamping frame slide of the compaction mechanism. The two are embedded and cooperate to form a high-precision sliding pair, allowing the tamping frame slide to slide up and down only in the vertical direction, providing stable guidance for the compaction operation.

[0023] IV. Strengthening the Core Execution: The compaction mechanism is an independent functional module and is the core component for achieving soft foundation compaction. The connection relationships and functions of each component are as follows: The ramming frame is a box-shaped welded structure that serves as the main load-bearing skeleton of the ramming mechanism. The top is welded with a first lug for connecting the high-speed hydraulic cylinder. The sides or key internal locations are welded with ramming frame slides to form a rigid whole with the ramming frame. The lower flange is fastened to the upper flange of the ramming base shell by bolts.

[0024] High-speed hydraulic cylinder: As the core component of impact power, the tail of the cylinder body is hinged to the first lug via a pin, and can rotate slightly around the pin to accommodate installation errors; the end of the piston rod is rigidly connected to the hammer body via a flange and bolts, which can drive the hammer body to lift and release at high speed, providing impact energy for compaction operations.

[0025] Hammer body and energy transmission components: The hammer body is a heavy block made of high-density metal, located directly above the hammer pad; the hammer pad is placed in the upper part of the cylindrical cavity inside the tamping base shell, and is supported by the tamping base structure at the bottom, which is used to buffer the direct impact of the hammer body, protect the tamping base and evenly distribute stress; the bottom of the tamping base shell is equipped with a removable baffle, which is fixed to the lower flange surface of the shell by bolts to prevent soil from rushing into the cavity or the tamping base from accidentally falling out during operation.

[0026] Rammer lifting cylinder: used to drive the overall lifting of the ramming mechanism. The cylinder body is hinged to the rammer lifting cylinder cylinder body connecting seat of the connecting frame through the middle pin. The end of the piston rod is connected to the second ear seat at the top of the rammer slide through the pin. Its extension and retraction can directly drive the rammer and its components to rise and fall vertically along the connecting frame slide.

[0027] Limiting mechanism: The limiting plate is welded to a specific position on the inner side of the tamping frame slide according to the preset compaction depth. When the compaction operation reaches the preset depth, the limiting plate contacts the upper edge of the connecting frame slide, mechanically limiting the tamping frame from sinking further, realizing automatic tamping stop, and prompting the operator to move the machine.

[0028] Operating posture control: The operating posture control system consists of the boom cylinder and bucket cylinder built into the skid steer loader itself, as well as the tamping frame lifting cylinder added to this equipment, forming a multi-degree-of-freedom fine-tuning posture system. Before operation, the tamping frame lifting cylinder is fully extended, lowering the tamping mechanism to its lowest position; then, the boom cylinder and bucket cylinder are adjusted to fine-tune the spatial angle of the connecting frame, ensuring that the bottom surface of the tamping base is stable and fully conforms to the uneven soft foundation surface, laying the foundation for vertical and efficient tamping.

[0029] The equipment is equipped with an electro-hydraulic control system, the core of which is a human-machine interface control box (which can be placed in the cab or remotely controlled). Through this control box, the operator can steplessly adjust the piston stroke of the high-speed hydraulic cylinder (i.e., the lifting height of the hammer body, and precisely control the single impact energy) and the working frequency, so as to achieve switching between multiple compaction modes from low frequency high energy (deep reinforcement) to high frequency medium energy (surface compaction), adapting to different soil types and depth requirements; at the same time, the operator can control the extension and retraction of the tamping frame lifting cylinder to realize the lifting and lowering operation of the compaction mechanism.

[0030] In summary, compared with the prior art, the present invention has the following significant advantages: 1. High mobility and adaptability to narrow and complex working conditions: Using the skid steer loader as a mobile platform, its compact body, all-wheel drive and on-the-spot turning ability, combined with the quick-change device, enable the rapid assembly and disassembly of the compaction mechanism, solving the problem of traditional equipment being unable to "enter" the area. It can flexibly enter and exit narrow breaches and muddy areas, greatly improving equipment deployment efficiency and emergency response speed.

[0031] 2. Controllable energy, balancing deep and shallow reinforcement needs: The electro-hydraulic control system allows for stepless adjustment of the stroke and frequency of the high-speed cylinder, enabling precise control of impact energy. It can switch between low-frequency high-energy (deep reinforcement) and high-frequency medium-energy (surface compaction) modes. Combined with the efficient energy transfer structure of hammer body-hammer pad-rammer base, it solves the problem of "inadequate compaction" in traditional equipment. It is suitable for various soft foundation soils such as high-moisture silt and backfill soil, balancing surface compaction and deep reinforcement needs.

[0032] 3. Controllable operation, safe and stable with no secondary risks: The precise guidance and coordination between the tamping frame slide and the connecting frame slide ensures vertical impact of the hammer, reducing energy loss and lateral disturbance; the addition of a limit plate enables automatic stopping of tamping at the preset depth, preventing over-tamping from damaging the structure of the filled body, solving the problem of "uncontrollable" traditional equipment, avoiding the induction of secondary landslides or seepage damage, and ensuring operational safety and the stability of reinforcement quality.

[0033] 4. High efficiency and continuous operation, significantly improving emergency response efficiency: The working posture control system composed of multiple hydraulic cylinders can quickly complete the horizontal alignment adjustment of the ramming base, and there is no need to repeatedly adjust the boom posture when moving; the continuous operation cycle of "ramming-lifting-moving" minimizes ineffective working time, solves the problem of "low efficiency" of traditional equipment, and is particularly suitable for the practical needs of tight breach sealing schedules.

[0034] 5. Reliable structure and easy operation: The connection relationship of each component is clear. It adopts a structural design that combines rigid welding and precision hinges, which has strong load-bearing capacity and good stability. The electro-hydraulic control system is equipped with a user-friendly operation box, which can adjust the operating parameters in real time. The equipment operation status is intuitive and controllable. Those skilled in the art can quickly master the operation process according to the instruction manual and drawings, which is convenient for on-site implementation and maintenance.

Detailed Implementation

[0036] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0037] like Figures 1-8 As shown, the hydraulic rapid compaction equipment of the present invention, suitable for soft ground reinforcement during the process of sealing dike breaches, includes a skid steer loader body 1, a quick-change device 5, a connecting frame 8, a compaction mechanism 9, and an operation posture control system. The quick-change device 5 is installed at the front end of the boom 3 of the skid steer loader body 1; The compaction mechanism 9 slides with the connecting frame slide 19 of the connecting frame 8 via the tamping frame slide 14. The rear end of the connecting frame 8 is matched and connected with the quick-change device 5, so as to realize the quick assembly, disassembly and fixation of the compaction mechanism 9 and the skid steer loader body 1. The compaction mechanism 9 includes a high-speed hydraulic cylinder 10, a tamping frame 18, a hammer body 12, a tamping base 13, a hammer pad 17 and a tamping frame lifting hydraulic cylinder 11. The tail of the cylinder body of the high-speed hydraulic cylinder 10 is hinged to the first lug 21 on the top of the ramming frame 18 by a pin. The piston rod end of the high-speed hydraulic cylinder 10 is connected to the hammer body 12 by a flange, which is used to drive the hammer body 12 to move up and down reciprocally. The tamping base 13 is fastened to the lower flange of the tamping frame 18 by bolts through the upper flange of the tamping base shell 22. The hammer pad 17 is placed in the upper part of the inner cylindrical cavity of the tamping base shell 22, and the hammer body 12 is located directly above the hammer pad 17. The bottom of the tamping base shell 22 is provided with a detachable baffle 23. The lower end of the cylinder body of the ramming frame lifting cylinder 11 is hinged to the connecting seat 20 on the connecting frame 8 by a pin. The piston rod end of the ramming frame lifting cylinder 11 is connected to the second ear seat 16 at the top of the ramming frame slide 14 by a pin, which is used to drive the ramming frame 18 to rise and fall vertically along the connecting frame slide 19. The working posture control system is composed of the boom cylinder 2, bucket cylinder 4 and rammer frame lifting cylinder 1 of the skid steer loader body 1, and is used to adjust the working posture and levelness of the rammer mechanism 9.

[0038] The quick-change device 5 is equipped with a mechanical locking mechanism and a hydraulic control function. The mechanical locking mechanism includes a pin 6. By moving the quick-change handle 7 up and down, the connecting frame 8 and the boom 3 can be quickly locked and unlocked, and the hydraulic pipeline can be automatically connected at the same time.

[0039] The tamping frame 18 is a box-shaped welded structure. The tamping frame slide 14 is welded to both sides or inside the tamping frame 18 and forms a rigid whole with the tamping frame 18. The connecting frame slide 19 is welded to the connecting frame 8. Its inner cavity size is precisely matched with the tamping frame slide 14 to form a high-precision sliding pair, which restricts the tamping frame 18 to slide only in the vertical direction.

[0040] The present invention also includes an electro-hydraulic control system, which is set in an operating box. The operating box is placed in the skid steer loader cab or is remotely controlled. It is used to steplessly adjust the piston stroke and working frequency of the high-speed hydraulic cylinder 10, and to control the extension and retraction of the ramming frame lifting cylinder 11.

[0041] The hammer body 12 is made of high-density metal, and the hammer pad 17 is made of high-elasticity, high-wear-resistant material, which is polyurethane or special rubber.

[0042] A limiting plate 15 is welded to the inner side of the tamping frame slide 14 to limit the maximum downward stroke of the tamping frame 18 and achieve automatic stopping of tamping at the preset depth. The welding position of the limiting plate 15 is determined according to the preset tamping depth. When the tamping frame 18 sinks to the point where the limiting plate 15 contacts the upper edge of the connecting frame slide 19, the tamping frame 18 stops sinking. At this time, the tamping frame lifting cylinder 11 reaches the lower limit of the stroke simultaneously.

[0043] The adjustment process of the working posture control system is as follows: First, fully extend the ramming frame lifting cylinder 11 so that the ramming mechanism 9 is lowered to the lowest position; then adjust the boom cylinder 2 and the bucket cylinder 4, and finely adjust the spatial angle of the connecting frame 8 so that the bottom surface of the ramming base 13 is stably attached to the soft foundation surface.

[0044] The baffle 23 is fixed to the lower flange of the ramming base housing 22 by bolts to prevent soil from flowing into the ramming base housing 22 or the ramming base 13 from accidentally falling out during operation.

[0045] The electro-hydraulic control system can switch between impact modes. By adjusting the stroke and frequency of the high-speed hydraulic cylinder 10, it can achieve multiple compaction modes from low frequency and high energy to high frequency and medium energy, adapting to different soil types and reinforcement depth requirements.

[0046] The skid steer loader body 1 has all-wheel drive and on-the-spot steering functions, and its hydraulic output system provides power to the high-speed cylinder 10, the ramming frame lifting cylinder 11, the boom cylinder 2 and the bucket cylinder 4.

[0047] The construction process of the equipment of this invention specifically includes the following steps, in which the coordinated actions of the components are clearly defined, ensuring that those skilled in the art can implement the process according to the procedure: Step 1: Working Condition Assessment and Parameter Planning. An investigation is conducted on the work area after the breach is sealed to assess the properties of the backfill soil, its moisture content, the thickness of the soft soil layer, and the spatial conditions of the work surface. Based on the assessment results, the construction layers, the target compaction depth for each layer, the grid layout of compaction points, and the preliminary range of impact energy and frequency parameters are planned.

[0048] Step 2: Quick connection and positioning of equipment. Operate the skid steer loader body 1 to the work site, and quickly install the compaction mechanism 9 using the quick-change device 5: Align the interface of the quick-change device 5 with the front of the connecting frame 8, and move the quick-change device handle 7 up and down to complete the mechanical locking and hydraulic pipeline connection; then operate the skid steer loader to the designated compaction area.

[0049] Step 3: Coarse posture adjustment and tamping frame descent. Operate boom cylinder 2 and bucket cylinder 4 to move the tamping mechanism 9 roughly above the work point; operate tamping frame lifting cylinder 11 to extend it fully, and drive the tamping frame 18 to descend along the connecting frame slide 19 until the tamping base 13 contacts the ground.

[0050] Step 4: Fine leveling of the working surface. Ensure that the lifting cylinder 11 of the ramming frame has a certain supporting force, and then finely adjust the boom cylinder 2 and the bucket cylinder 4 again. Observe and ensure that the bottom surface of the ramming base 13 is fully and stably in contact with the soft foundation surface, and complete the calibration of the working posture.

[0051] Step 5: Parameter Setting and Compaction Start. Using the control box, set the stroke (impact energy) and working frequency of the high-speed hydraulic cylinder 10 according to the current soil conditions. Start the working mode of the high-speed hydraulic cylinder 10. The hydraulic system drives the high-speed hydraulic cylinder 10 to quickly lift the hammer 12 to the set height and then release it. Under the action of gravity and hydraulic assistance, the hammer 12 impacts the hammer pad 17 at high speed. The energy is transferred to the foundation through the tamping base 13 to achieve a single tamping. The high-speed hydraulic cylinder 10 moves continuously back and forth to complete the continuous tamping operation.

[0052] Step 6: Process Monitoring and Automatic Compaction Stop. During continuous compaction, the foundation is compacted and settles, causing the compaction frame 18 and the compaction frame slide 14 to sink synchronously along the connecting frame slide 19. The operator monitors the foundation settlement and equipment operation status in real time. When the limit plate 15 sinks with the compaction frame 18 to contact the upper edge of the connecting frame slide 19, the compaction frame 18 is mechanically limited and cannot continue to sink, indicating that the preset compaction depth has been reached. At this time, the compaction frame lifting cylinder 11 reaches the lower limit of its stroke, and the compaction at this point is automatically terminated.

[0053] Step 7: Lifting and moving the tamping mechanism. Operate the tamping frame lifting cylinder 11 to retract, driving the tamping frame 18 and its components to rise vertically along the connecting frame slide rail 19, completely lifting the tamping base 13 off the ground; keep the current angle of the skid loader boom 3 and connecting frame 8 unchanged (i.e., do not adjust the boom cylinder 2 and bucket cylinder 4), operate only the skid loader body 1 walking system, and move the equipment to the next pre-set tamping point.

[0054] Step 8: Cyclic Operation and Area Coverage. At the next compaction point, repeat the operation process from Step 3 to Step 7, completing the soft foundation compaction and reinforcement of the entire work area through a continuous cycle of "positioning—leveling—setting—compacting—stopping compaction—lifting—moving".

[0055] The above embodiments illustrate the basic principles and features of the present invention, but are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
