Support pile construction process for soft soil base enclosure
The invention discloses a supporting pile construction technology for soft soil base enclosure. The supporting pile construction technology comprises the following steps that firstly, a timber pile is used for marking points on the ground, and then a circle is drawn at the position with the radius of 1 m by using lime with the timber pile as the circle center, then, a drilling machine is used for forming a plurality of inclined drill holes in the circle at equal intervals, cement paste is injected into the inclined drill holes, and then the inclined drill holes are subjected to landfill; an inclined drill hole is formed, grouting is conducted in the inclined drill hole, then cement paste is injected into a foundation soil layer through a high-pressure jet grouting pile machine above the grouting position in a jet grouting mode, stirring is conducted, the cement paste injected later and the cement paste injected first are stirred together, and after solidification, the cement paste in the inclined drill hole becomes a supporting leg expanding outwards; and the supporting force of the hard supporting solid structure in the soft soil is increased.
本发明公开了一种软土基地围护用的支撑桩施工工艺包括以下步骤：步骤一、在地面使用木桩进行标点，接着根据木桩为圆心在其半径为1米处使用石灰进行画圆圈，接着使用钻机在圆圈上等间距开设多个倾斜钻孔并在倾斜钻孔的内部注入水泥浆，然后将倾斜钻孔进行填埋；通过设置倾斜钻孔，在倾斜钻孔的内部进行注浆，然后在其注浆的上方通过高压旋喷桩机地基土层旋喷注入水泥浆，并且搅拌，后注入的水泥浆和先注入的水泥浆搅拌在一起，凝固之后倾斜钻孔内部的水泥浆成为向外扩张的支撑脚，增加硬质支撑固体结构在软土内部的支撑力。
