Miniature steel pipe pile retaining wall foundation reinforcing method
The invention discloses a micro steel pipe pile retaining wall foundation reinforcing method. The method comprises the following steps that S1, a side slope is temporarily supported; s2, pile position lofting is carried out, and multiple steel pipe pile lowering drilling positions are marked on a second platform from top to bottom; s3, drilling construction is conducted, specifically, drilling is conducted in the position marked in the S2, and a drilled hole is formed; s4, steel pipe machining; s5, the steel pipe is installed, before the steel pipe is hoisted and placed, ballast in the drill hole is cleaned through high-pressure air, and then the steel pipe is aligned with the drill hole position to be installed in the lower hole; the construction technology of the miniature steel pipe pile retaining wall is simple, convenient and rapid to construct, small in occupied space, small in pile top displacement, high in construction efficiency and small in risk, and the effect of applying the miniature steel pipe pile retaining wall to steep terrain mountain retaining engineering and landslide control is obvious.
本发明公开了一种微型钢管桩挡土墙基础加固方法，包括以下步骤：步骤S1、边坡临时支护；步骤S2、桩位放样，在从上往下的第二个平台上标记多个钢管桩下放钻孔位置；步骤S3、钻孔施工，在S2标记好的位置钻孔，形成钻孔；步骤S4、钢管加工；步骤S5、钢管安装，在吊放钢管之前，使用高压风对钻孔内的石碴进行清理，再将钢管对准钻孔位进行下孔安装；步骤S6：注浆，步骤S7：冠梁施工，本发明的微型钢管桩挡土墙施工工艺简单施工方便而快捷、占用场地小、桩顶位移小、施工效率高且风险小，应用于陡峭地形山体支挡工程及滑坡治理效果明显。
