Pile construction method in complex environment ultra-deep foundation pit support
The invention discloses a pile construction method in complex environment ultra-deep foundation pit support. The pile construction method mainly comprises three-axis stirring pile construction and SPCW construction method pile construction. The three-axis stirring pile construction comprises the steps of obstacle clearing, surveying and setting out, groove digging, pile driver in-place, cement grout preparing and grout injecting, drilling stirring, cleaning, shifting, etc. The SPCW construction method pile construction comprises the steps of positioning profile steel placing, pipe pile hoisting, pipe pile inserting and conveying, pipe pile fixing, etc. According to the pile construction method, construction is convenient, and quality is good.
本发明公开了一种复杂环境超深基坑支护中的桩施工方法，主要包含：三轴搅拌桩施工、SPCW工法桩施工；三轴搅拌桩施工包括：障碍物清理、测量放线、开挖沟槽、桩机就位、制备水泥浆液及浆液注入、钻进搅拌、清洗、移位等步骤；SPCW工法桩施工包括：安放定位型钢、管桩起吊、插入管桩送桩、管桩固定等步骤。本发明施工方便，质量好。
