Loess area miniature steel pipe pile construction method
The invention discloses a loess area miniature steel pipe pile construction method. The loess area miniature steel pipe pile construction method comprises the following steps that S1, design is conducted, specifically, the positions of a plurality of sets of pile positions are designed through a GPS, pile position coordinates marked on a drawing are set out to the field earth surface through GPS measuring equipment, and fine adjustment is conducted according to the actual using condition of the actual position; S2, preparation before construction is conducted, specifically, an actual needed punching point is marked, needed punching equipment is mounted at the actual position and aligned with the punching point, and a reaction frame and a jack are mounted; S3, construction drilling is conducted, specifically, the punching equipment is used for punching the punching point, a steel pipe is immediately put down after pile hole forming is completed, hole collapse is prevented, the length of the steel pipe is selected according to the actual needs, slurry outlet holes are evenly distributed in the outer wall of the steel pipe, then the jack is used for pressing the steel pipe downwards, and anchoring parts are connected to the periphery of the steel pipe; and S4, grouting is conducted. According to the loess area miniature steel pipe pile construction method, the round pipe can be pressed and tamped, and the stability and quality of the round pipe can be guaranteed through concrete.
本发明公开了一种黄土地区微型钢管桩施工方法，包括以下步骤：S1、设计：利用GPS设计多组桩位的位置，并利用GPS测量设备将图纸上标示的桩位坐标放样到现场地表，并根据实际位置的实际使用情况进行微调；S2、施工前准备：标记好实际需要打孔点，在实际位置上安装需要的打孔设备，并将打孔设备对准打孔点，并安装反力架和千斤顶；S3、施工钻孔：利用打孔设备对打孔点进行打孔，桩孔完成后立即下方钢管，防止塌孔，钢管的长度根据实际需要进行选择，钢管外壁均布出浆孔，然后利用千斤顶对钢管下压，并在钢管外周连接锚固件；S4、注浆。该黄土地区微型钢管桩施工方法，不仅能够压紧夯实圆管，还能利用混凝土保证圆管的稳定性和品质。
