Description

Technical Field

[0001] The invention relates to the technical field of highway construction, and in particular to a soft soil foundation processing device for highway construction. Background Art

[0002] Soft soil foundation is composed of silt, silty soil, miscellaneous fill or other highly compressible soft soil layers. Soft soil foundation is a soft soil layer with low strength and high compression. It has high saturated liquid level, is sensitive to force, has poor stability and low bearing capacity, and is easy to cause embankment instability and structural damage. Therefore, before highway construction, the soft soil foundation needs to be treated first; The replacement method is one of the methods used to reinforce saturated soft soil foundations. Its main principle is to dig out the soft soil layer and replace it with materials with high strength and good stability (such as sand, gravel, lime soil, etc.). The replacement method is simple to construct and has significant effects. It can quickly improve the bearing capacity of the foundation and is widely used. However, the replacement filling method requires multiple steps such as excavation, backfilling, and compaction during the construction process. Each step requires the use of different equipment to operate, and the equipment cost is relatively high. During construction, the backfill material is usually poured directly on the foundation and then spread manually, which requires high work intensity. At the same time, it is difficult to achieve uniform distribution through manual operation, which not only affects the flatness of the foundation, but may also cause gaps between the filling materials, resulting in reduced density of the foundation, which in turn affects the service life of the road. Summary of the invention

[0003] The purpose of the present invention is to provide a soft soil foundation processing device for highway construction to solve the problems raised in the above background technology.

[0010] Furthermore, the compaction assembly includes two synchronous turntables, and the two synchronous turntables are fixedly connected to a connecting shaft on one side close to the inner wall of the support frame, and the two connecting shafts are rotatably connected to the inner walls on both sides of the support frame, and the two synchronous belts are respectively mounted on the two connecting shafts, and the two synchronous turntables are fixedly connected to a connecting rod on one side close to each other, and sliding rods are fixedly connected to the two connecting rods.

[0011] Furthermore, the compaction assembly also includes two synchronous plates, which are respectively located on the side of the two synchronous turntables close to each other.

[0014] 2. In the present invention, the first synchronous shaft can drive the synchronous rod to rotate by starting the second driving motor, and the multiple impact cams on the synchronous rod continuously impact the bottom of the blanking plate, causing the blanking plate to vibrate. This vibration promotes the uniform distribution of the filling material falling on the blanking plate, and with the help of the diversion effect of the diverter rod and the diverter plate, it is further ensured that the filling material falls evenly through the blanking chute. The uniform material discharge ensures the laying quality of the filling material on the foundation, making the foundation more flat and dense.

[0015] 3. In the present invention, when the second drive motor is started, the synchronous belt can also drive the connecting shaft on the synchronous turntable to rotate, so that the connecting shaft drives the synchronous turntable to rotate, and the connecting rod and the sliding rod on the synchronous turntable move at the same time, driving the two synchronous plates to move up and down, and then driving the compacting plate to move up and down to compact the fallen filling material. This synchronous compaction design can perform compaction operations immediately after the filling material falls, avoiding the problems of looseness and settlement of the filling material due to untimely compaction, and greatly improving the strength and stability of the foundation.

[0016] In summary, in the present invention, from cleaning the soft soil layer to compacting the filling material, each process is smooth and connected without excessive human intervention, which reduces the pause and waiting time during the construction process and further improves work efficiency. At the same time, this coherent workflow also reduces construction costs and improves the economic benefits of the project. BRIEF DESCRIPTION OF THE DRAWINGS
