Description

Technical Field

[0001] The invention relates to mechanical equipment for drilling and digging in soil and rock, in particular to a grouting hydraulic screw drill. Background Art

[0002] Grouting hydraulic spiral drilling machines are widely used in the fields of pile foundation construction, foundation reinforcement and deep foundation pit support in construction projects, especially in dealing with complex geological conditions such as soft soil and sandy soil, showing high construction efficiency. However, traditional drilling equipment has some technical bottlenecks in the construction process, especially in deep construction, where problems such as insufficient stability, unstable power output and low drilling accuracy are more prominent. These problems not only lead to a decrease in construction efficiency, but may also affect the final project quality.

[0003] At present, traditional spiral drilling machines are mostly driven by hydraulic power and cooperate with rotating drill rods to break and lift the soil layer. However, the chassis structure of existing equipment is often simply designed, which makes it difficult to ensure the stability of the equipment in complex terrain. Especially in sites with unstable foundations or large slopes, the drilling rig is prone to tilt and slide, which in turn affects the verticality of the drilled hole. In addition, due to the imperfect design of the power system, the equipment may experience insufficient power output or transmission failure when working for a long time and at high intensity, reducing the drilling efficiency.

[0004] In addition, during the grouting construction process, the traditional equipment has relatively weak positioning and protection measures for the drill rod, which often causes the drill rod to shake or deviate during high-speed rotation, affecting the drilling accuracy and even causing damage to the equipment itself. Grouting construction places higher requirements on the high-precision positioning and stability of the drill rod. Therefore, a grouting hydraulic spiral drill with optimized structure, precise positioning and stable power output is needed to meet the requirements in complex construction environments.
