Description

Technical Field

[0001] The invention relates to mechanical equipment for drilling and excavating in soil and rock, and in particular to a grouting hydraulic spiral drilling machine. Background Art

[0002] Grouting hydraulic auger drills are widely used in construction projects for pile foundation construction, ground reinforcement, and deep foundation pit support. They demonstrate high efficiency in complex geological conditions, such as soft soil and sandy soil. However, traditional drilling equipment faces technical bottlenecks during construction, particularly in deep-seated drilling operations, where issues such as insufficient stability, unstable power output, and low drilling accuracy are particularly prominent. These issues not only reduce construction efficiency but also compromise the final quality of the project.

[0003] Currently, traditional auger drills are mostly hydraulically driven, using a rotating drill rod to break up and lift soil. However, existing equipment often features a simple chassis design, making it difficult to ensure stability in complex terrain. This is especially true in areas with unstable foundations or steep slopes, where the drill rig is prone to tilting and sliding, affecting the verticality of the drilled hole. Furthermore, due to imperfect power system design, prolonged, high-intensity operation can lead to insufficient power output or transmission failure, reducing drilling efficiency.

[0004] Furthermore, during grouting, traditional equipment lacks sufficient positioning and protection for the drill rod, often causing it to wobble or deflect during high-speed rotation, affecting drilling accuracy and potentially damaging the equipment itself. Grouting operations place higher demands on the drill rod's high-precision positioning and stability. Therefore, a grouting hydraulic auger with optimized structure, precise positioning, and stable power output is needed to meet the requirements of complex construction environments. Summary of the Invention

By strengthening the connection strength of key components such as the chassis and main frame, and adopting various fixing methods such as bolts and wedge blocks, the durability of the equipment is greatly enhanced, reducing failures caused by structural loosening or wear during long-term construction. At the same time, the design of the outrigger components, support rods, and other parts makes the overall frame of the equipment more stable, extending the service life of the equipment.
