摘要
针对１ ７８０ 工程复杂的地质条件，在人工挖孔灌注桩施工中采用“钢护筒沉筒法”或“孔下预制钢筋混凝土沉筒法”穿过了流沙层，解决了钢筋笼吊装、水下浇灌混凝土等施工关键问题，取得了较好效果。
A downhole sinking cylinder method of precast reinforced concrete penetrating through a quick sand layer is used for the construction of the cast in place pile of hand dug hole according to the complicated geological conditions.The key problems of hoisting of cage of rebar and of tremie concrete etc are solved with good results.
