Abstract

The invention discloses a cement stirring pile head and particularly discloses a single-shaft multidirectional cement stirring pile head which structural comprises a gear train mechanism, wherein thegear train mechanism realizes rotation stirring around the screw-in direction of the stirring pile head. In addition, the invention also provides a multi-shaft multidirectional cement stirring pile head formed through combination at least two single-shaft multidirectional cement stirring pile heads. The single-shaft multidirectional cement stirring pile head solves the technical problem that cemented soil on the pile body is ensured to be fully stirred uniformly to the maximum and has the advantages of being high in pile forming quality and pile body quality and low in production cost.

Description

technical field [0001] The invention relates to a cement mixing pile head, in particular to a single-axis multi-directional cement mixing pile head and a multi-axis multi-directional cement mixing pile head. Background technique [0002] In the composite foundation treatment of buildings in the prior art, stirring piles are usually used for reinforcement. The method is to stir the foundation soil through mechanical blades, so that it is uniformly mixed with the added cement slurry to form a pile body to reinforce the foundation. Because the pile body adopts the material of the foundation itself, the cost is low, but due to the poor adaptability of the ground, the uniformity of mixing is not easy to grasp, the construction quality is difficult to control, and the construction efficiency is low. [0003] In order to solve the above problems, there have been many improved mixing drills, the most representative of which are two-way mixing drills and drill bits. For example, the...
