Narrow space slurry protection wall drilling pile construction method
The invention relates to a construction method for a slurry retaining wall drilled pile in a narrow space, which comprises the following steps of: determining a reasonable piling sequence according to a drawing and a field environment, performing positioning and lofting on each pile position by using a theodolite and a steel tape according to a design requirement, and placing a pile position line so as to determine a pile foundation point position; drilling equipment is assembled, and drilling construction is conducted; the steel pipe pile is inserted into the drilled hole, and grouting construction is conducted after elevation measurement and adjustment; according to the mechanical rotation principle, the design that the pistol drill and the gear driving set are combined is adopted, and the drill rod with the spiral drill bit arranged at the head is driven to drill holes; no space is occupied in the construction process, and transferring is convenient; the device is easy to use, convenient to maintain, capable of saving construction cost and improving efficiency, high in construction speed and good in use convenience. And in cooperation with slurry, wall protection is conducted on a pile body, lubricating is conducted in the drilling process, and the pressure of the inner side and the outer side during pile hole drilling is balanced to guarantee the stability of the pile body. The method is suitable for drilling pile engineering operation with complex foundation pit side environment conditions and a small working face.
一种狭小空间泥浆护壁钻孔桩施工方法，根据图纸及现场环境，确定合理的打桩顺序，每个桩位按照设计要求，利用经纬仪、钢卷尺进行定位放样，并放好桩位线，以确定桩基点位；对钻孔设备组装、并进行钻孔施工；将钢管桩插入钻孔内，经标高测量调整后进行注浆施工；本发明利用机械转动原理，采用手枪钻与齿轮驱动组相结合的设计，带动头部设置螺旋钻头的钻杆进行钻孔；施工过程中不占场地，转移方便；使用简单，维修方便，可以节约施工成本，提高功效，施工速度快，具有良好的使用便利性。配合泥浆，对桩身进行护壁，对钻孔过程进行润滑，平衡钻取桩孔时内外侧压力保证桩身稳定性。此方法适用于基坑边环境条件复杂，工作面较小的钻孔桩工程作业。
