Method for controlling protection layer of reinforcement cage of rotary excavating cast-in-place pile and preventing hole collapse
The invention discloses a method for controlling a protection layer of a reinforcement cage of a rotary excavating cast-in-place pile and preventing hole collapse, and relates to the technical field of building construction. The method for controlling the protection layer of the reinforcement cage of the rotary excavating cast-in-place pile and preventing hole collapse comprises the following steps that S1, after rotary excavating machine drilling inspection and acceptance are qualified, a hole pile reinforcement cage is bound on site; and S2, cushion blocks with the thickness equal to the design thickness of a reinforcement cage protection layer are evenly bound to the outer edge of the reinforcement cage in the circumferential direction and the length direction, and the cushion blocks are prefabricated cushion blocks. According to the method for controlling the protection layer of the reinforcement cage of the rotary excavating cast-in-place pile and preventing hole collapse, in order to overcome the defects that a reinforcement cage deviates and peripheral loose soil or scum is prone to entering the reinforcement cage when concrete is poured into a rotary excavating cast-in-place pile, a steel wire mesh isolation measure is adopted for the pile in the construction process, it is ensured that the integrity and stability of a pile body are guaranteed, an isolation steel wire mesh is simple in structure and convenient to manufacture, and the forming quality of the pile foundation can be effectively controlled in construction.
本发明公开了一种旋挖灌注桩钢筋笼保护层控制和防塌孔的方法，涉及建筑施工技术领域。该旋挖灌注桩钢筋笼保护层控制和防塌孔的方法，包括如下操作：S1、在旋挖机械钻孔验收合格后，现场绑扎孔桩钢筋笼，S2、在钢筋笼外沿圆周及长度方向均匀绑扎一些厚度等于钢筋笼保护层设计厚度的垫块，其中垫块为预制垫块。该旋挖灌注桩钢筋笼保护层控制和防塌孔的方法，为克服旋挖灌注桩在浇筑混凝土时钢筋笼偏位及周边松散土体或浮渣易进入钢筋笼内部，在施工过程中对桩采取钢丝网片隔离措施，确保保证桩身完整性、稳定性，隔离钢丝网片结构简单、制作方便，在施工中能有效控制桩基的成型质量。
