Description
Technical Field
The utility model relates to the technical field of building construction, in particular to a drill bit device of a cement mixing pile machine.
Background
The region of China is very broad, various soil bodies are distributed from coastal to inland, and a large amount of soft soil exists in the soil bodies, wherein most of the soft soil is distributed in coastal regions of China and inland coastal and lake regions, such as coastal regions of Guangzhou, Shanghai, Hangzhou, Tianjin, Fuzhou, Ningbo and the like, and inland coastal and lake regions of Wuhan, Nanjing, Changsha, Kunming and the like; the soft soil is mainly characterized by large water content, large pore ratio, large compressibility, poor water permeability and the like, when a structure is built on the soft soil foundation soil, because the bearing capacity of the soft soil is low, great settlement can be generated after stress is applied, the structure is easy to be unevenly settled, the structure is inclined, and the structure is unstable; therefore, in engineering practice, when a soft soil foundation is met, manual treatment is needed, and a cement soil stirring method is used as a method for treating the soft soil foundation, cement is used as a curing agent, and the cement and water react to form a cement soil stirring pile with sufficient strength between the soft soil and the cement, so that a composite foundation is formed; compared with other methods, the cement-soil stirring method can utilize original soil, has the advantages of simple construction, low cost, deep reinforcement and the like, is more and more emphasized by people, and is particularly applied to marine silt and mucky soil on a large scale.
The cement deep layer stirring method in China firstly starts in 1976, special research and development work is carried out by national subordinate enterprises, and the first deep layer stirring machine independently researched in China is successful in 1978, the stirring machine is named as an SJB-1 type double-shaft stirring machine, the maximum reinforcement depth of the stirring machine is 10m, and the machine is formally adopted in the actual soft soil foundation construction in the Shanghai in 1980 and has good reinforcement effect; the Tianjin and the Zhongjiu engineering office in the same year are cooperated to develop a GZB-600 type single-shaft stirring machine, the maximum reinforcement depth is 15m, and the GZB-600 type single-shaft stirring machine is applied to the actual soft foundation treatment engineering in the second year and is successful; a single-shaft deep cement mixer named DJS-2 type single-shaft mixer is manufactured by Zhejiang university and cooperative construction unit thereof in 1983, and the maximum reinforcement depth of the mixer is 18 m; in more than ten years later, companies manufacture mixers capable of spraying cement powder and cement paste successively, and meanwhile, the construction depth of the cement-soil mixing pile reaches 30 m; the cement-soil mixing pile is applied in China from the 80 s, the application range is wider and wider, and good economic benefits are obtained.
However, when the conventional common cement mixing pile machine drills downwards in a rotating mode in a soil layer, the drill bit blades are very easy to be wrapped by clay and are gradually adsorbed on the drill bit blades to form mud balls, the wrapped drill bit blades cannot effectively cut soil and drill downwards, a drill bit of the cement mixing pile idles in situ, the drilling speed is rapidly reduced, the mixing pile machine needs to be cleaned by the drill bit, a large amount of working hours are consumed, the drilling efficiency is reduced, and the construction period is delayed.
