Construction elevator foundation steel pipe pile reinforcing construction method
The invention discloses a construction elevator foundation steel pipe pile reinforcing construction method. The method comprises the steps of carrying out steel pipe pile construction preparation; setting out a pile position; enabling a drilling machine to be in place, carrying out hole site remeasurement, and determining the drilling depth; process hole forming; placing steel pipe piles; mounting a grouting guide pipe; repeatedly washing away mud and other sundries in the grouting guide pipe by using high-pressure clear water till return water in the pipe becomes clear; and pouring cement paste into the grouting guide pipes through an injection pump machine. According to the construction elevator foundation steel pipe pile reinforcing construction method, after plain soil is backfilled layer by layer, the steel pipe piles are constructed, a construction elevator foundation is poured on the upper portions of the steel pipe piles, the steel pipe piles serve as supports, it is guaranteed that the bearing capacity of the lower portion of the construction elevator foundation meets the requirement, construction is easy, safety is good, and economy and applicability are achieved.
本发明公开了一种施工电梯基础钢管桩加固施工方法，包括：钢管桩施工准备；桩位放样；钻机就位，进行孔位复测和确定钻孔深度；工艺成孔；钢管桩安放；注浆导管安装；利用高压清水反复冲刷注浆导管内的泥浆等杂物，直至管内回水变清；利用注泵机向各所述注浆导管内灌注水泥浆。上述施工电梯基础钢管桩加固施工方法，素土分层回填后，施工钢管桩，在钢管桩上部浇筑施工电梯基础，以钢管桩作为支撑，保证施工电梯基础下部的承载力达到要求，其施工简单，安全性好，经济适用。
