Water-rich sandy gravel geological pile group hole forming construction method
The invention provides a hole-forming construction method for a water-rich sandy gravel geological group pile. The hole-forming construction method comprises the steps of construction investigation, site leveling and construction lofting, positioning protection pipe installation, primary drilling, long protection pipe installation, secondary drilling, hole cleaning, reinforcement cage hoisting and placing, underwater concrete pouring, protection pipe pulling out and the like. The method is high in construction efficiency, small in environmental pollution and large in safety coefficient, and the quality is guaranteed.
本发明提供一种富水砂卵石地质群桩成孔施工方法，包括施工勘察、场地平整及施工放样、定位护管安装、一次钻进、长护管安装、二次钻进、清孔、吊放钢筋笼、水下混凝土浇筑、护管拔出等步骤。本发明施工效率高、环境污染小、安全系数大、质量有保证。
