Water-rich sandy gravel geological pile group hole forming construction method
The invention discloses a water-rich sandy gravel geological pile group hole-forming construction method which comprises the following steps of construction investigation, paying-off and pile position fixing, mounting of a positioning pile casing, primary drilling, mounting of a protection pile casing (1), secondary drilling, hole cleaning and hoisting and placing of a reinforcement cage lamp.The method includes the following steps that firstly, construction investigation is sufficient, pile casing materials are prepared in advance, material preparation can be optimized in combination with construction organizations, and the construction efficiency is improved; the pile casing machining and coring time is saved, and under the general condition, the whole pile casing is installed, and the protection wall forming efficiency is high; 2, drilling is performed twice, and the hole forming part influenced by rich water follows the protective casing, so that the mounting time of the protective casing is greatly saved; and (3) the steel wire mesh can effectively reduce the time for lowering steel bar holes and cleaning sediments at the bottom of the pile. The method is high in construction efficiency, small in environmental pollution, large in safety coefficient, capable of guaranteeing quality and suitable for hole forming construction of the rock-socketed rotary excavating pile in the water-rich sandy gravel geology.
本发明公开了一种富水砂卵石地质群桩成孔施工方法，包括以下步骤：施工勘察、放线定桩位、安装定位护筒、一次钻进、安装防护护筒(1)、二次钻进、清孔、吊放钢筋笼灯，该方法①施工勘察充分，护筒材料提前制备，可结合施工组织优化备料，节省护筒加工及取芯时间，一般情况下，整根安装，护壁成形效率高；②分两次钻进，受富水影响的成孔部分方才跟进护防护护筒，大大节省了护筒安装时间；③钢丝网可有效减少下放钢筋孔、清理桩底沉渣的时间。该方法施工效率高、环境污染小、安全系数大、质量有保证，适用于富水砂卵石地质嵌岩旋挖桩成孔施工。
