CFG pile foundation construction method for improving foundation bearing capacity
The invention provides a CFG pile foundation construction method for improving the foundation bearing capacity. The CFG pile foundation construction method comprises the following steps that S1, an original ground is cleaned and leveled; s2, surveying and setting out; s3, a drilling machine is in place; s4, drilling is conducted; s5, concrete is pumped; s6, the drill is evenly pulled out to the pile top; s7, drilling machine displacement; s8, soil between the piles is removed; s9, cutting a pile head; s10, performing test detection; s11, pile cap construction; s12, soil between the piles is backfilled; and S13, constructing a mattress layer. According to the CFG pile foundation construction method for improving the bearing capacity of the foundation, the bearing capacity of the soft foundation is improved; the construction period is shortened, and the construction speed is high; construction machinery is low in noise, and equipment walks flexibly; environmental pollution such as slurry and sewage is reduced; the hole pattern is easy to keep complete, and the precision is high; labor intensity is low and work efficiency is high; the method is suitable for foundation treatment of various industrial and civil buildings and highway engineering, and is massively used for reinforcing high-rise and super high-rise building foundations.
本发明提供一种提升地基承载力的CFG桩基施工工法，包括以下步骤：S1、原地面清理整平；S2、测量放线；S3、钻机就位；S4、钻孔；S5、泵送砼；S6、均匀拔钻至桩顶；S7、钻机移位；S8、清除桩间土；S9、切桩头；S10、试验检测；S11、桩帽施工；S12、桩间土回填；S13、褥垫层施工。本提升地基承载力的CFG桩基施工工法增加软弱地基承载能力；缩短施工周期，施工速度快；施工机械噪音低，设备行走灵活；减少泥浆、污水等环境污染；易保持孔型完整，精度较高；劳动强度低，工效高；适用于各种工业、民用建筑及公路工程的地基处理，大量用于高层和超高层建筑地基的加固。
