Cement stirring pile construction method
The invention relates to a cement stirring pile construction method. The method comprises the steps of first-time downward drilling, wherein a drill bit of a stirring head drills with clear water downuntil the stirring head drills to be close to the design depth, in the process, a slurry spraying opening of the drill bit always sprays out the clear water, the slurry spraying opening of the drillbit sprays cement slurry and continues sinking to the design depth, and the drill bit stays at the expected depth for a period of expected time; first-time elevation, wherein the drill bit of the stirring head rotates and rises to the reserved height, and in the process, the slurry spraying opening always sprays the cement slurry; follow-up down drilling, wherein the drill bit of the stirring headdrills down to the design depth, and in the process, the slurry spraying opening does not work; follow-up lifting, wherein the drill bit of the stirring head rotates and is lifted to the reserved height, and in the process, the slurry spraying opening always sprays the cement slurry; and the follow-up down drilling step and the follow-up lifting step are at least carried out by one round. The method effectively increases the construction speed and reduces the construction cost.
本发明涉及一种水泥搅拌桩施工方法。其包括：第一次下钻步骤；搅拌头的钻头带清水下钻直到搅拌头钻至靠近设计深度，此过程中，钻头的喷浆口一直喷清水；然后钻头的喷浆口变为喷水泥浆液并继续下沉至设计深度；钻头在预计深度停留一段预计时间；第一次提升步骤；搅拌头的钻头旋转并提升至预定高度，此过程喷浆口一直喷水泥浆液；后续下钻步骤，搅拌头的钻头下钻至设计深度；此过程喷浆口不作业；后续提升步骤，搅拌头的钻头旋转并提升至预定高度，此过程喷浆口一直喷水泥浆液；后续下钻步骤和后续提升步骤至少进行一个回合。本发明有效提供施工速度，降低施工成本。
