Abstract

The invention relates to a drill bit system for a root-shaped mixing pile. The system comprises a drill spindle, a common mixing structure, a telescopic mixing fulcrum bar structure, a drill bit top structure and a mixing spindle regulating power system; the common mixing structure is a common mixing rod-shaped structure arranged on the outside wall of the drill spindle, the telescopic mixing fulcrum bar structure is a telescopic mechanical-arm-shaped structure which is telescopic and can conduct rotary mixing, the telescopic mixing fulcrum bar structure is arranged on the outside wall of the drill spindle, the drill bit top structure is fixed to the lower end of the drill spindle, and the mixing spindle regulating power system is arranged outside the drill spindle and automatically controls and regulates mixing of the telescopic mixing fulcrum bar structure to generate the root-shaped mixing pile. The system has the advantages of fully intelligent control, novel and practical structure, and convenient and rapid construction, saving labor of construction staff, being convenient to manage and maintain, saving construction investment by a large margin and the like.

Description

technical field [0001] The invention relates to a ground reinforcement treatment equipment, in particular to a drill bit system for a root-shaped mixing pile. Background technique [0002] The mixing pile method is suitable for soft foundation treatment, and the effect is remarkable. After treatment, piles and walls can be formed. For example, deep cement mixing piles are suitable for treating silt, sandy soil, silty soil, peat soil and silt. Commonly used mixing piles include: cement mixing piles, curing agent mixing piles, and high-pressure jet spraying piles. The cross-sections of current mixing piles are generally circular with equal cross-sections, that is, the area replacement rate of piles in the composite foundation reinforcement area does not change with depth. [0003] Stirring piles are a commonly used treatment method for soft foundations. Due to different depositional reasons, in some layered weak foundations, the mechanical properties of soil at different depth...
