Description

Technical Field

[0001] This utility model belongs to the field of silty clay cement filling construction technology, specifically relating to a paving device for volcanic ash silty clay cement filling construction. Background Technology

[0002] In the field of civil engineering, especially in the construction of infrastructure such as roads, dams, and airport runways, the strength and stability of the subgrade are key factors in ensuring project quality. Volcanic ash silty clay, as a special type of soil material, often fails to meet the compaction and strength requirements of engineering projects due to its high liquid limit and plastic limit characteristics. To improve this situation, cement modification is commonly used in engineering practice. This involves mixing a certain proportion of cement into the volcanic ash silty clay and adjusting the moisture content of the mixture to near the optimum moisture content so that subsequent compaction operations can achieve the specified compaction standards. After the cement is mixed with the high liquid limit volcanic ash silty clay, a series of chemical reactions occur, promoting soil consolidation. This not only increases the soil strength but also seals the gaps between soil clumps, forming a stable bonded structure. After compaction, the cement gradually hardens, resulting in a significant increase in strength, thereby effectively improving the overall strength of the subgrade and providing a solid foundation for the long-term stability of the engineering structure.

[0003] In the construction of cement-modified volcanic ash silty clay, the spreading of the fill material is a crucial step. Traditionally, the fill material is transported to the filling area by dump trucks, and then spread and leveled using a grader to ensure the uniformity and flatness of the fill layer. However, existing grader devices have certain limitations in spreading operations. Specifically, the length of the paving bucket of a traditional grader is fixed. Although the grader can adapt to different working conditions by controlling the raising, lowering, or rotating of the paving bucket, the length of the paving bucket itself cannot be limited. Adaptive adjustments based on actual paving needs not only reduce paving efficiency to some extent but also limit the paving range, especially when dealing with large areas or specially shaped fill areas. Furthermore, the connection between the paving bucket and the upper boom of a traditional grader requires continuously lifting the paving bucket before connecting it with multiple bolts. This is laborious during actual lifting and installation, and it is difficult to ensure quick alignment of the bolt holes, affecting installation efficiency. Therefore, this utility model proposes a paving device for volcanic ash silty clay cement fill construction. Utility Model Content

At the same time, this design also enhances the flexibility of the entire device, enabling it to better adapt to paving operations under different working conditions. In addition, this application innovatively adopts a connection method of hanging and bolt locking to tightly connect the paving bucket back seat and the upper arm seat together, which not only ensures the stability of the connection and fixation, but also simplifies the installation process and improves the installation efficiency. In the actual installation process, it is only necessary to first hang the paving bucket back seat directly under the upper arm seat to achieve suspension support without the need for external additional support equipment, and then lock it with multiple bolts, which greatly improves the convenience and efficiency of installation.
