Carbonization composite mixing pile process
The invention relates to the technical field of foundation soil reinforcement, and discloses a carbonization composite mixing pile process which comprises the following steps: step 1, selecting a position where a mixing pile needs to be arranged, and cleaning surface sundries and underground obstacles; secondly, distribution points of the stirring piles are arranged according to requirements, and specific coordinates of the stirring piles are measured; thirdly, the material conveying assembly and the three-shaft mixing pile machine body are moved to mixing pile distribution points; 4, cement paste, lime slurry and carbon dioxide are prepared through a material conveying assembly; fifthly, the first drill rod, the second drill rod, the third drill rod, the first drill bit and the second drill bit at the power head end of the three-shaft mixing pile machine body are used for sinking, and construction operation is conducted on the mixing pile; according to the process, lime is added to be mixed with cement and fully mixed with carbon dioxide, the carbonization reaction is accelerated, a hard calcium carbonate substance is generated, the setting time is shortened, and the strength of a pile body is improved.
本发明涉及地基土加固技术领域，且公开了一种碳化复合搅拌桩工艺，包括以下步骤：步骤一、选取需要设置搅拌桩的位置，并清理地表杂物和地下障碍物；步骤二、按照要求设置搅拌桩的分布点，并测量出具体的搅拌桩坐标；步骤三、将输料组件和三轴搅拌桩机主体移动至搅拌桩分布点；步骤四、使用输料组件准备水泥浆、石灰浆和二氧化碳；步骤五、使用三轴搅拌桩机主体动力头端的三个第一钻杆、第二钻杆、第三钻杆、第一钻头和第二钻头下沉，对搅拌桩进行施工操作；本工艺通过加入石灰与水泥混合，并与二氧化碳充分混合，加速碳化反应，生成质地坚硬的碳酸钙物质，缩短凝结时间，增加桩体的强度。
