Description

Technical Field

[0001] This utility model relates to the technical field of heavy hammer compactors, specifically a heavy hammer compactor for foundation treatment in collapsible loess areas. Background Technology

[0002] Collapsible loess refers to loess that is prone to significant settlement and volume changes under certain moisture conditions, especially after contact with water. This soil type is typically distributed in Northwest and North China, as well as other arid and semi-arid regions. The unique properties of collapsible loess pose challenges to engineering construction and infrastructure development. Therefore, understanding the characteristics, distribution, and treatment methods of collapsible loess is crucial for ensuring project quality. Collapsible loess is characterized by its tendency to undergo substantial settlement under varying moisture conditions, particularly after contact with water. These characteristics make it challenging to use as foundations for buildings, transportation, and infrastructure projects due to its stability and bearing capacity issues. To address this problem, specialized foundation treatments for collapsible loess are often required, with heavy-duty compactors being a commonly used and effective tool.

[0003] Existing compaction machines compact the foundation by striking the ground with a heavy hammer. However, in collapsible loess areas, the heavy hammer strikes cause soil to splash, which may result in some soil layers not being fully compacted, especially the surface soil being carried away by the splash, causing uneven compaction and affecting the overall stability of the foundation. To address these issues, the inventors propose a heavy hammer compaction machine for foundation treatment in collapsible loess areas. Utility Model Content

[0004] To address the problem that existing compaction machines, which use heavy hammers to compact the ground during foundation treatment, often cause soil to splash during impacts in collapsible loess areas, resulting in uneven compaction, especially as topsoil is carried away, thus affecting the overall stability of the foundation, this invention aims to provide a heavy hammer compactor for foundation treatment in collapsible loess areas. By incorporating a compaction lifting assembly, the machine utilizes its heavy hammer to compact the foundation. The force of the hammer is transferred to the soil during the compaction process, effectively increasing soil density. The repeated impacts of the hammer ensure a tight packing of soil particles.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by setting up a tamping lifting component, the foundation can be tamped using the hammer of a tamping machine. The force of the hammer is transmitted to the soil through the tamping process, which can effectively improve the soil density. The repeated impact of the hammer can make the soil particles tightly packed, reducing the porosity, thereby improving the bearing capacity of the foundation. Through tamping treatment, the stability of the foundation is enhanced. Especially in soft or loose soil layers, the tamping action of the hammer can effectively improve the compressive strength of the soil, reduce settlement or displacement, and thus ensure the safety of buildings or other structures. Compared with traditional manual or other methods, using the hammer of a tamping machine can significantly increase the tamping speed, save manpower and material resources, and speed up the construction progress. Especially in large-scale infrastructure projects, it can effectively shorten the construction period.

[0015] In this invention, by designing a heavy-duty mudguard, the loss of surface soil that may be caused by mud splashing can be avoided, which would affect the uniformity of the compaction effect. Avoiding splashing helps ensure the integrity of the soil, enhances the uniformity of the compaction operation, and makes the foundation compaction more uniform and stable, thereby improving the bearing capacity of the foundation. Avoiding mud splashing also helps reduce the cleaning and maintenance work of the equipment, thereby reducing equipment wear and tear, increasing equipment lifespan, and reducing cleaning work also helps reduce interruptions in construction, thereby improving the overall construction efficiency.

[0041] Working principle: When a heavy hammer compactor is needed for foundation treatment in collapsible loess areas, the first motor 205 drives the second gear 208 to rotate, which in turn drives the first gear 207 to rotate. Furthermore, the first gear 207 drives the first drum 210 to rotate, and the rotation of the first drum 210 allows the lifting connection line 109 to be wound around it. The movement of the lifting connection line 109 drives the third wheel 311 and the second wheel 310 to rotate, ultimately causing the compactor hammer 104 to move up and down. Finally, the compactor hammer 104 can be used to compact the foundation. The force of the hammer is transmitted to the soil through the compaction process, which can effectively improve the soil density. The repeated impact of the hammer can make the soil particles tightly arranged, reducing the porosity, thereby improving the bearing capacity of the foundation. Through compaction, the stability of the foundation is enhanced.

[0042] By designing the heavy hammer mudguard 101, the loss of topsoil that may be caused by mud splashing can be avoided, which would affect the uniformity of the compaction effect. Avoiding splashing helps to ensure the integrity of the soil, enhances the uniformity of the compaction operation, and makes the foundation compaction more uniform and stable, thereby improving the bearing capacity of the foundation. Avoiding mud splashing also helps to reduce the cleaning and maintenance work of the equipment.
