The invention discloses an X-shaped vibrating rod. The X-shaped vibrating rod comprises a vibrating rod body, wherein a cross section of the vibrating rod body is of an X-shaped structure, an obliqueincluded angle of the vibrating rod body of the X-shaped structure is 45-60 degrees, opening teeth are arranged on four wing side edges of the vibrating rod body at equal intervals, and round holes are formed in four wing side surfaces of the vibrating rod body at equal intervals in the length direction. The X-shaped vibrating rod is simple in design structure and convenient to use, a soil plug effect produced near a rod shaft when a cross vibrating rod is used can be avoided, vibrating energy can be effectively transmitted, and the optimal compacting effect is realized; by means of the designed opening teeth, actual cross-sectional area and impedance of the vibrating rod can be reduced, relatively large amplitude is produced, the opening teeth resonate easily with soil mass, vibrating compaction is facilitated, meanwhile, by design of the opening teeth, rigidity and weight of the vibrating rod are reduced, flexibility of the vibrating rod during loading is realized, the greater the flexibility is, the larger the density range is, and the compacting effect can be improved by geometric design of the vibrating rod.
Description
technical field [0001] The invention relates to the design field of vibrating rods used in vibrating compaction treatment of collapsible loess foundations, in particular to an X-shaped vibrating rod. Background technique [0002] my country's loess covers more than 220 counties and cities in Northwest China, North China and other provinces, covering an area of 630,000 square kilometers, accounting for about 6.6% of the country's land area. It has the characteristics of wide distribution, thick layers, and complex genetic types. The water sensitivity, macroporosity, and collapsibility caused by the structure of loess make it prone to instability and landslides, earthquake subsidence and collapsibility under the action of external loads (such as earthquakes, engineering vibrations, etc.) and water. Promoting the construction of the "Belt and Road" economic belt and the construction of the national strategy of "Yellow River Basin Ecological Protection and High-quality Develop...
