Description

Technical Field

[0001] This invention relates to the field of foundation treatment and soil improvement equipment technology, and more specifically to a foundation reinforcement equipment that integrates the functions of tamping hammer, vibratory compaction and feeding. Background Technology

[0002] Foundation treatment is a crucial step in civil engineering construction, significantly impacting the stability and safety of buildings and infrastructure. Common methods for large-area foundation reinforcement include dynamic compaction and vibro-compaction. Dynamic compaction primarily uses the impact force generated by the free fall of an object to improve soil density and is widely used for surface soil reinforcement. Vibro-compaction, on the other hand, utilizes deep vibration technology to improve the granular structure of the soil, showing significant advantages, particularly in the treatment of collapsible soils, loose soils, and sandy soils.

[0003] However, with the increasing scale of construction and the emergence of different soil types, a single technology (such as tamping or vibro-compaction) may not achieve the desired reinforcement effect under complex conditions. For example, dynamic compaction mainly works on surface soil and has limited effectiveness on deep soil, especially in water-saturated areas or collapsible soil layers. Vibro-compaction can treat deep soil, but it requires a large amount of equipment and space during construction, and its effect on hard soil layers is not ideal. In addition, equipment with only one method has poor adaptability to the environment during actual construction. When multiple processing methods need to be used in combination, multiple machines need to operate simultaneously, which greatly increases labor costs and significantly reduces work efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a foundation reinforcement device that integrates the functions of tamping hammer, vibratory compaction and feeding, aiming to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foundation reinforcement device integrating tamping, vibratory compaction, and feeding functions, comprising:

[0007] A vertical vibratory compaction module, wherein the vertical vibratory compaction module has a feeding pipe inside, the top of the vertical vibratory compaction module has an open filling port that communicates with the feeding pipe, and the bottom of the vertical vibratory compaction module has a discharge port that communicates with the feeding pipe.

[0008] A feeding rack is located on the top outer side of the vertical vibratory compaction module. A feeding box is rotatably connected to the top of the feeding rack. The backfill material in the feeding box can be poured into the filling port by rotating the feeding box.

[0009] The annular drop hammer is coaxially arranged outside the vertical vibroflotation body module, and the top surface is connected with the bottom surface of the feeding frame through an automatic lifting unlocking mechanism.

[0010] Through the above technical scheme, the tamper, the vibroflotation and the feeding function are integrated, the equipment switching and the carrying time are reduced, and the construction efficiency is improved. It can adapt to different geological conditions and complex soil layers, such as collapsible soil and loose soil, and solve the problem that the traditional single reinforcement method has poor effect under complex conditions. By integrating multiple reinforcement functions, the construction process and the cooperation time between the equipment are reduced, the construction period is shortened, and the construction cost is reduced.

[0011] Preferably, in the above-mentioned ground reinforcement equipment integrating tamper, vibroflotation and feeding functions, a movable control blade driven by electricity is installed on the discharge port. The movable control blade driven by electricity can accurately control the output amount and timing of the filling material, ensure the uniform distribution of the backfill material, and improve the effect of ground reinforcement. Through the opening and closing of the electric control blade, automatic filling control is realized, manual intervention is reduced, and the accuracy and safety of construction are improved. The flow and speed of the filling material can be flexibly adjusted according to the construction requirements, and different ground reinforcement scenes and soil conditions can be adapted.

[0012] Preferably, in the above-mentioned ground reinforcement equipment integrating tamper, vibroflotation and feeding functions, the lifting unlocking mechanism includes an electric control hook and a drop hammer lifting ring, the electric control hook is installed on the bottom surface of the feeding frame, the drop hammer lifting ring is connected to the top surface of the annular drop hammer, the drop hammer lifting ring is hung on the electric control hook, and the electric control hook can control the separation from the drop hammer lifting ring, thereby releasing the annular drop hammer. The use of the electric control hook realizes the automatic release and recovery of the annular drop hammer, reduces the complexity and risk of manual operation, and improves the construction efficiency. The release timing of the drop hammer can be accurately controlled to ensure the accurate transmission of the tamper impact force and improve the effect of ground reinforcement. The unlocking and hooking operation of the drop hammer are realized through the electric control system, which avoids the safety hazards caused by manual operation.

[0013] Preferably, in the above-mentioned ground reinforcement equipment integrating tamper, vibroflotation and feeding functions, the drop hammer lifting ring is rotationally connected to the top surface of the annular drop hammer, and the annular drop hammer has a motor inside for controlling the rotation of the drop hammer lifting ring. The rotational connection of the drop hammer lifting ring and the motor control make the drop hammer flexible in position adjustment during the release and recovery process, ensuring the stability and accuracy of the lifting. Through the motor control of the rotation of the lifting ring, the direct friction between the lifting ring and the electric control hook is reduced, and the service life of the equipment is prolonged. The quick and accurate lifting and release process enables the equipment to work continuously, improving the construction efficiency.

[0014] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibroflotation and feeding functions, the hoisting unlocking mechanism further comprises a visual alignment system. The visual alignment system can accurately identify the position of the ring-shaped drop hammer, ensuring the accuracy of the hoisting and releasing process and avoiding construction accidents caused by positional deviation. Through the cooperation of the visual system and the electric control hook lock, fully automated hoisting and releasing operations are realized, 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, ensuring stable operation of the equipment.

[0015] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibroflotation and feeding functions, a hydraulic cylinder is connected between the top surface of the feeding rack and the feeding box, and the hydraulic cylinder can drive the feeding box to overturn. The hydraulic cylinder drives the feeding box to overturn, realizing an automated feeding process, reducing manual operation and improving construction efficiency. The hydraulic cylinder can accurately control the overturning 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 feeding. The use of a hydraulic system reduces the direct contact of mechanical components, reducing equipment failure and operation risks.

[0016] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibroflotation 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 discharge pipeline, avoiding material accumulation and blockage and improving feeding efficiency. The funnel-shaped structure can minimize the scattering and waste of backfill materials, reducing construction costs. The funnel-shaped box body can accommodate 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, vibroflotation and feeding functions, the top surface of the feeding rack has a hoisting ring. The design of the hoisting ring allows the feeding rack to be easily connected to the sling system, facilitating the hoisting and moving of the equipment and improving the flexibility of construction. The hoisting ring provides a stable hoisting point, ensuring the balance and safety of the equipment during hoisting and avoiding equipment damage or accidents caused by improper hoisting. This simplifies the installation and disassembly process of the equipment, improving the overall efficiency of construction.

[0018] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibroflotation and material feeding functions, the bottom end of the vertical vibroflotation body module is a cone head structure with protruding vibration blocks on both sides. The cone head structure effectively reduces the resistance of the vertical vibroflotation body module during lowering, making it easier to penetrate the soil layer and improving the penetration ability of the equipment. The design of the vibration blocks enhances the transmission efficiency of the vibration, allowing it to act more uniformly on the soil layer and improving the effect of foundation reinforcement. The combination of the cone head structure and the vibration blocks better adapts to different types of soil layers, including hard soil layers and collapsible soil layers, improving the versatility and adaptability of the equipment.

[0019] Preferably, in the above-mentioned foundation reinforcement equipment integrating rammer, vibroflotation and material feeding functions, the vertical vibroflotation body module is driven by an eccentric block rotating by a motor to generate high-frequency vibration, or a hydraulic motor is used as the power driven by a hydraulic power system. The hydraulic motor drives the eccentric shaft to rotate through a shaft coupling, thereby generating horizontal excitation force and amplitude distributed along the axial direction of the main shaft. The motor or hydraulic motor driven vibration system can generate high-frequency vibration, effectively improving the particle structure of the soil layer and improving the density and bearing capacity of the foundation. The use of a hydraulic power system provides strong power support to ensure the stable operation of the vibration system, especially suitable for deep soil layer reinforcement. The vibration frequency and amplitude can be flexibly adjusted according to the soil conditions and construction requirements to achieve precise reinforcement and improve the adaptability and construction effect of the equipment.

[0020] Through the above technical solutions, compared with the prior art, the present application provides a foundation reinforcement equipment integrating rammer, vibroflotation and material feeding functions, which has the following advantages:

[0021] 1. The equipment integrates rammer, vibroflotation method into one, which can complete various reinforcement tasks in the same operation process, greatly improving the construction efficiency. Compared with the traditional method of alternating work of multiple equipment, this equipment reduces the equipment switching and carrying time, and improves the engineering progress.

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

[0023] 3. Traditional equipment often faces the problem of low coordination efficiency and power waste. The design of this equipment uses an intelligent coordination control system, so that the rammer, vibration and grouting components can be smoothly switched and work together, greatly improving the energy utilization efficiency and reducing unnecessary energy waste.

[0024] 4、The design of the device takes into account various complex soil layers, and can flexibly adjust the operation parameters according to the compactness and bearing capacity requirements of the soil layer, to ensure that the reinforcement effect reaches the best. In addition, the device has strong adaptability in geotechnical engineering, and is suitable for application in engineering projects under different environmental conditions.

[0025] 5、Intelligent control and automated operation process greatly reduces the possibility of manual intervention and operation errors.

At the same time, the intelligent detection system can monitor the running state of the device in real time, and take timely feedback and measures to avoid accidents. BRIEF DESCRIPTION OF DRAWINGS
