Description

Technical Field

[0001] The invention relates to the technical field of foundation treatment and soil improvement equipment, and more particularly to a foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions. Background Art

[0002] Ground treatment is an important part of civil engineering construction, and has a significant impact on the stability and safety of buildings and infrastructure. Common foundation reinforcement methods suitable for large areas include dynamic compaction and vibroflotation. Dynamic compaction mainly generates impact force by free falling objects to improve the density of the soil layer, and is widely used in the reinforcement of the surface soil; vibroflotation improves the particle structure of the soil through deep vibration technology, especially in the treatment of collapsible soil, loose soil, sandy soil and other foundations.

[0003] However, with the increase in construction scale and the emergence of different soil types, a single technology (such as tamping hammer or vibroflotation) may not be able to achieve the desired reinforcement effect under complex conditions. For example, the dynamic tamping method mainly acts on the surface soil, and has limited effect on deep soil, especially in problematic soil layers such as water-saturated areas or collapsible soil. The vibroflotation method can handle deep soil, but a large amount of equipment and space are required during the construction process, and the treatment effect on hard soil layers is not ideal. In addition, equipment with only a single method has poor adaptability to the environment in the actual construction process. When multiple processing methods are required, multiple machines need to operate simultaneously, which greatly increases labor costs and greatly reduces work efficiency. Summary of the invention

[0004] In view of this, the present invention provides a foundation reinforcement device integrating rammer, vibration and feeding functions, aiming to solve the above technical problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A foundation reinforcement device integrating tamping hammer, vibrating and feeding functions, comprising:

[0007] A vertical vibroflotation module, wherein a feed pipe is provided inside the vertical vibroflotation module, a top end of the vertical vibroflotation module has an open filling port connected to the feed pipe, and a bottom end of the vertical vibroflotation module has a discharge port connected to the feed pipe;

[0008] A feeding rack, the feeding rack is arranged on the outside of the top of the vertical vibroflotation module, the top of the feeding rack is rotatably connected to a feeding box, and the backfill material in the feeding box can be poured into the filling port by rotating the feeding box;

[0009] An annular drop hammer is coaxially arranged on the outside of the vertical vibrating body module, and the top surface of the annular drop hammer is connected to the bottom surface of the feeding rack through an automatic lifting and unlocking mechanism.

[0010] Through the above technical solution, the present invention integrates the functions of tamping hammer, vibro-impacting and feeding, reduces the time of equipment switching and transportation, and improves the construction efficiency. It can adapt to different geological conditions and complex soil layers, such as collapsible soil, loose soil, etc., and solves the problem that the traditional single reinforcement method is not effective under complex conditions. By integrating multiple reinforcement functions, the collaborative operation time between construction processes and equipment is reduced, the construction period is shortened, and the construction cost is reduced.

[0011] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, an electrically driven movable control blade is installed on the discharge port. The electrically driven movable control blade can accurately control the output amount and output timing of the filler, ensure the uniform distribution of the backfill material, and improve the effect of foundation reinforcement. By electrically controlling the opening and closing of the blades, automatic filler control is achieved, reducing manual intervention and improving the accuracy and safety of construction. The flow rate and speed of the filler can be flexibly adjusted according to the construction requirements to adapt to different foundation reinforcement scenarios and soil conditions.

[0012] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, the lifting unlocking mechanism includes an electrically controlled hook lock and a drop hammer ring, the electrically controlled hook lock is installed on the bottom surface of the feeding rack, the drop hammer ring is connected to the top surface of the annular drop hammer, the drop hammer ring is hung on the electrically controlled hook lock, and the electrically controlled hook lock can be controlled to be separated from the drop hammer ring, thereby releasing the annular drop hammer. The use of the electrically controlled hook lock realizes the automatic release and recovery of the annular drop hammer, reduces the tediousness and risks of manual operation, and improves construction efficiency. The release timing of the drop hammer can be accurately controlled to ensure the accurate transmission of the impact force of the rammer and improve the effect of foundation reinforcement. The unlocking and hooking operation of the drop hammer is realized through the electric control system, avoiding the potential safety hazards caused by manual operation.

[0013] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibratory impact and feeding functions, the drop hammer lifting ring is rotatably connected to the top surface of the annular drop hammer, and the inside of the annular drop hammer has a motor for controlling the rotation of the drop hammer lifting ring. The rotational connection and motor control of the drop hammer lifting ring enable the drop hammer to flexibly adjust its position during the release and recovery process, thereby ensuring the stability and accuracy of the lifting. By controlling the rotation of the lifting ring through the motor, the direct friction between the lifting ring and the electric-controlled hook lock is reduced, thereby extending the service life of the equipment. The fast and accurate lifting and releasing process enables the equipment to operate continuously, thereby improving the construction efficiency.

[0014] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, the lifting and unlocking mechanism also includes a visual alignment system. The visual alignment system can accurately identify the position of the annular drop hammer, ensure the accuracy of the lifting and releasing process, and avoid construction accidents caused by position deviation. Through the cooperation of the visual system and the electric-controlled hook lock, fully automated lifting and releasing operations are achieved, reducing manual intervention and improving the safety and efficiency of construction. In complex construction sites, the visual alignment system can quickly adapt to environmental changes and ensure the stable operation of the equipment.

[0015] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, a hydraulic cylinder is connected between the top surface of the feeding frame and the feeding box, and the hydraulic cylinder can drive the feeding box to flip. The hydraulic cylinder drives the feeding box to flip, realizing an automated feeding process, reducing manual operations and improving construction efficiency. The hydraulic cylinder can accurately control the flipping angle and speed of the feeding box, ensuring that the backfill material can be accurately poured into the filling port, and improving the uniformity and accuracy of the feeding. The use of the hydraulic system reduces the direct contact of mechanical parts and reduces equipment failure and operation risks.

[0016] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, the feeding box is a funnel-shaped box body. The design of the funnel-shaped box body allows the backfill material to flow smoothly into the feeding pipe, avoiding material accumulation and blockage, and improving the feeding efficiency. The funnel-shaped structure can minimize the scattering and waste of backfill materials and reduce construction costs. The funnel-shaped box body can adapt to backfill materials of different particle sizes and types, improving the versatility of the equipment.

[0017] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, the top surface of the feeding frame has a lifting ring. The design of the lifting ring enables the feeding frame to be easily connected to the sling system, which is convenient for the lifting and movement of the equipment and improves the flexibility of construction. The lifting ring provides a stable lifting point to ensure the balance and safety of the equipment during the lifting process and avoid equipment damage or accidents caused by improper lifting. The installation and disassembly process of the equipment is simplified and the overall efficiency of the construction is improved.

[0018] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibration and feeding functions, the bottom end of the vertical vibrating body module is a cone head structure, and has protruding vibration blocks on both sides. The cone head structure can effectively reduce the resistance of the vertical vibrating body module during the lowering process, making it easier to penetrate the soil layer and improving the penetration ability of the equipment. The design of the vibration block enhances the transmission efficiency of the vibration, so that the vibration can act on the soil layer more evenly, improving the effect of foundation reinforcement. The combination of the cone head structure and the vibration block can better adapt to different types of soil layers, including hard soil layers and collapsible soil layers, thereby improving the versatility and adaptability of the equipment.

[0019] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibro-impact and feeding functions, the vertical vibro-impact module generates high-frequency vibrations by driving the eccentric block to rotate through a motor, or adopts hydraulic power to drive a hydraulic motor as power, and the hydraulic motor drives the eccentric shaft to rotate through a coupling, thereby generating horizontal exciting force and amplitude distributed along the main axis. The vibration system driven by the motor or hydraulic motor can generate high-frequency vibrations, effectively improve the particle structure of the soil layer, and improve the density and bearing capacity of the foundation. The use of the hydraulic power system provides powerful power support to ensure the stable operation of the vibration system, and is particularly suitable for the reinforcement of deep soil layers. The vibration frequency and amplitude can be flexibly adjusted according to the soil layer conditions and construction requirements to achieve precise reinforcement and improve the adaptability and construction effect of the equipment.

[0020] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a foundation reinforcement device that integrates tamping hammer, vibro-impact and feeding functions, which has the following beneficial effects:

[0021] 1. The equipment integrates the tamping hammer and vibro-impact method into one, and can complete multiple reinforcement tasks in the same operation process, greatly improving construction efficiency. Compared with the traditional method that requires multiple devices to work alternately, this equipment reduces equipment switching and handling time, and improves project progress.

[0022] 2. Through the integrated intelligent control system, the equipment can automatically adjust the impact force and vibration frequency of the rammer according to soil conditions and operation requirements to achieve precise control. The system can provide real-time feedback on the soil reinforcement effect, automatically optimize operating parameters, and ensure that the reinforcement effect of each link meets the design requirements.

[0023] 3. Traditional equipment often faces the problems of low collaborative efficiency and power waste. The design of this equipment adopts an intelligent collaborative control system, which allows the rammer, vibration and grouting components to switch smoothly and work together, greatly improving energy utilization efficiency and reducing unnecessary energy waste.

[0024] 4. The design of the equipment takes into account a variety of complex soil layers, and can flexibly adjust the operating parameters according to the density and bearing capacity requirements of the soil layer to ensure the best reinforcement effect. In addition, the equipment has strong adaptability in geotechnical engineering and is suitable for engineering projects under different environmental conditions.

[0025] 5. Intelligent control and automated operation process greatly reduce the possibility of manual intervention and operational errors. The operator only needs to set relevant parameters and conduct remote monitoring, and the equipment can automatically complete complex reinforcement tasks, thereby greatly reducing labor costs and improving the safety and accuracy of construction.

[0026] 6. The safety design of the equipment is very complete, equipped with multiple safety measures such as overload protection, vibration isolation, and protective devices to ensure that operators can be fully protected in complex working environments. At the same time, the intelligent detection system can monitor the operating status of the equipment in real time, provide timely feedback and take measures to avoid accidents.

[0042] In order to further optimize the above technical solution, the lifting unlocking mechanism 6 includes an electrically controlled hook lock 7 and a drop hammer ring 8. The electrically controlled hook lock 7 is installed on the bottom surface of the feeding rack 2. The drop hammer ring 8 is connected to the top surface of the annular drop hammer 3. The drop hammer ring 8 is hung on the electrically controlled hook lock 7, and the electrically controlled hook lock 7 can be controlled to disengage from the drop hammer ring 8, thereby releasing the annular drop hammer 3.

[0043] The electric-controlled hook lock 7 provided in this embodiment can adopt Elebia evo series intelligent hook, NEO series hook or Demag four-hook chain electric hoist, which are conventional structures in the prior art and will not be described in detail here.

[0045] In order to further optimize the above technical solution, the lifting unlocking mechanism 6 also includes a visual alignment system.

[0046] In order to further optimize the above technical solution, a hydraulic cylinder 10 is connected between the top surface of the feeding rack 2 and the feeding box 5, and the hydraulic cylinder 10 can drive the feeding box 5 to flip.

[0047] In order to further optimize the above technical solution, the feeding box 5 is a funnel-shaped box body.

[0048] In order to further optimize the above technical solution, the top surface of the charging rack 2 is provided with a lifting ring 11 .

[0049] In order to further optimize the above technical solution, the bottom end of the vertical vibro-impact module 1 is a cone head structure, and has protruding vibration blocks 12 on both sides.

[0050] In order to further optimize the above technical solution, the vertical vibro-impact module 1 drives the eccentric block to rotate through a motor to generate high-frequency vibration, or uses hydraulic power to drive a hydraulic motor as power. The hydraulic motor drives the eccentric shaft to rotate through a coupling, thereby generating horizontal exciting force and amplitude distributed along the axial direction of the main shaft.

[0051] See attached Figure 6 The present embodiment provides a schematic diagram of the internal structure of a vertical vibroflotation module 1. The vertical vibroflotation module 1 consists of an outer tube 13 and an inner cabin 14. The gap between the outer tube 13 and the inner cabin 14 is a material discharge pipe. The outer tube 13 and the inner cabin 14 are fixed by multiple connecting rods 15 to improve the strength. The connecting rods 15 will not affect the material discharge. The interior of the inner cabin 14 is used to install components required for vibroflotation.

[0052] The equipment of this embodiment is equipped with an intelligent control system, including a data acquisition module and a data processing module, to achieve precise control of the working process.

[0053] Data acquisition module: collects soil parameter data through underground sensors (such as pressure sensors and vibration sensors). The sensors are arranged inside the rammer and vibro-impact modules and near the feeding module to obtain data such as soil density, porosity, soil bearing capacity, vibration response, etc. in real time.

[0054] Data processing module: The collected underground data is transmitted to the central processing system, which performs real-time analysis and prediction of the soil reinforcement effect based on the preset algorithm. The system can calculate the current soil bearing capacity and reinforcement requirements, and accurately control the parameters such as the impact energy, vibration frequency and grouting volume of the rammer to ensure the maximum reinforcement effect.

[0055] Installation and preparation of the equipment provided in this embodiment:

[0056] Determine the reinforcement points: According to the construction drawings or on-site survey, determine the points that need to be reinforced, and mark the grouting holes, backfill points and compaction areas.

[0057] Equipment installation: Place the equipment on top of the predetermined reinforcement point through the sling system, ensuring that the equipment is in a horizontal position and all components are intact.

[0058] Steps:

[0059] 1. Start the sling motor:

[0060] Start the sling motor and slowly lower the vertical vibroflotation module 1 to a predetermined depth.

[0061] Make sure the vibration head is in vibration mode and start drilling and digging operations.

[0062] At the same time, the charging frame 2 is lowered to a certain height along with another sling, and another excavator pours the required backfill sand and soil into the rotatable charging box 5 of the charging frame 2.

[0063] 2. Vibration and feeding:

[0064] When the vertical vibro-compacted body module 1 reaches a predetermined depth, the vertical vibro-compacted body module 1 starts to open the bottom movable blades and continues to vibrate to improve the soil structure.

[0065] At the same time, the hydraulic cylinder 10 is started, the feeding box 5 is rotated, and the backfill material is started to be injected.

[0066] 3. Vibration backfill and adjustment:

[0067] When the backfill material reaches a certain depth, the vertical vibroflotation module 1 will move upwards a certain distance to ensure the density and uniformity of the reinforcement layer.

[0068] The continuous vibration effect strengthens the bonding between backfill material and soil and improves the bearing capacity of soil.

[0069] Drop weight reinforcement:

[0070] 1. The electric-controlled hook lock 7 is released, and the annular drop hammer 3 falls freely, generating a strong tamping energy to compact the soil.

[0071] 2. Start the sling system, slowly lower the feeding rack 2, and use the visual recognition system to accurately locate the position of the annular drop hammer 3. When the annular drop hammer 3 is in place, the camera installed under the feeding rack 2 is used for manual alignment, and the electric control hook lock 7 re-hooks the annular drop hammer 3, driving the annular drop hammer 3 to rise, ready for the next compaction.

[0072] 3. Repeat the operation:

[0073] According to the needs of the project, repeat the above steps: vibration, backfilling, and drop hammer reinforcement.

[0074] Each mechanism can be started individually or used flexibly and alternately according to needs, providing a variety of reinforcement combinations to ensure the best reinforcement effect under different soil conditions.

[0075] Independent operation and coordinated use of equipment

[0076] Separate operation: Each reinforcement method (vibration, compaction) can be run separately as needed. Users can choose the most appropriate reinforcement method based on the on-site soil type, depth requirements, etc.

[0077] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
