Manufacturing technology for cement soil stirring pile
The invention discloses a manufacturing technology for a cement soil stirring pile. The manufacturing technology includes the following steps that firstly, a drill rod and cement soil are prefabricated; secondly, a cement soil stirring pile machine with the drill rod is used for conducting pile driving to a certain degree; thirdly, cement soil is poured into a hopper, and the cement soil enters the bottom of a second hollow pile pipe; fourthly, the cement soil stirring pile machine is used for lifting a first hollow pile pipe upwards with a certain speed to drive the second hollow pile pipe tobe lifted, a drill bit sinks around the hinge position between the drill bit and the second hollow pile pipe, gas in a soft clay foundation enters the second hollow pile pipe from a clearance betweenthe drill bit and the second hollow pile pipe along with soft clay and then is discharged into air through the first hollow pile pipe, and then the cement soil enters the soft clay from the clearancebetween the drill bit and the second hollow pile pipe; and fifthly, the second hollow pile pipe is drawn out of the soft clay foundation, after a period of time, the cement soil is solidified in thesoft clay foundation, the high-strength cement stirring pile is obtained, and the cement soil can be easily extruded into the soft clay foundation.
本发明公开一种水泥土搅拌桩制作工艺，包括如下步骤：步骤一，预制钻杆和水泥土；步骤二，利用带有所述钻杆的水泥土搅拌桩机进行打桩至一定的深度；步骤三，向料斗内倒入水泥土，水泥土进入第二空心桩管底部；步骤四，水泥土搅拌桩机向上以一定的速度提升第一空心桩管带动第二空心桩管抬升，钻头绕与第二空心桩管铰接位置处下沉，软粘土地基中气体随软粘土由钻头与第二空心桩管之间的空隙进入第二空心桩管内，再经过第一空心桩管排入空气中，然后水泥土再由钻头与第二空心桩管之间的空隙进入软粘土中；步骤五，第二空心桩管抽出软粘土地基，一段时间后，水泥土在软粘土地基中固化，得到高强度的水泥土搅拌桩，且水泥土容易挤入软粘土地基中。
