Pile construction method for re-expanding basement
The invention relates to the technical field of building construction, and discloses a pile construction method for re-expanding a basement. The method comprises the following steps of according to aconstruction scheme, laying out positioning lines on basement structural plates, and arranging a vertical support pipe between the basement structural plates; marking out a pile center position and acutting outline; drilling a hoisting hole, and fixedly connecting the hoisting hole to a hoisting device; drilling a cutting hole along the cutting outline, and hoisting away a concrete block to forma pile position hole; burying a steel guard cylinder at the pile position hole; digging soil in an underground layer along the steel guard cylinder to form a hole, and pouring a column pile; and pulling out the steel guard cylinder and backfilling the pile position hole. The pile foundation construction of an old basement structure re-expansion project is realized, through the mode, the foundationpile construction for re-expansion can be carried out without dismantling the old basement, the demolition and reconstruction cost of the old building is greatly saved, the construction cost is saved, and the method has good economic benefit.
本发明涉及建筑施工技术领域，公开了一种复扩建地下室桩施工方法，包括以下步骤：根据施工方案，在地下室结构板上放出定位线，在地下室结构板之间布置竖向支撑管；划出桩心位置以及切割轮廓；钻打吊装孔，并将吊装孔固定连接于吊装装置上；沿着切割轮廓钻打切割孔，吊走砼块，以形成桩位孔；在桩位孔上埋设钢护筒；沿着钢护筒往地下层挖土成孔并浇注柱桩；拔出钢护筒并回填桩位孔。实现对旧地下室结构复扩建项目的桩基础施工，该方式可以在不拆除旧地下室的情况下进行复扩建基础桩施工，大大节省了旧建筑拆除、重建费用，节约施工成本，具有较好的经济效益。
