Steel bar planting method for long spiral drilling pressure grouting pile and treatment method for not-in-place steel bar planting
The invention discloses a steel bar planting method for a long spiral drilling pressure-grouting pile and a treatment method for not-in-place steel bar planting, relates to the field of building construction, and aims to improve the success rate of steel bar planting and improve the construction quality. The adopted technical scheme is as follows: the steel bar planting method for the long spiral drilling pressure-grouting pile comprises the following steps: manufacturing a steel reinforcement cage of the long spiral drilling pressure-grouting pile; rolling wheels are installed on the outer side of the reinforcement cage, a dowel bar piece is fixedly installed at the bottom of the reinforcement cage or the position close to the bottom, the guide-in device and the reinforcement cage are assembled, the guide-in device and the reinforcement cage are implanted into concrete in a pile hole, finally, the guide-in device is pulled out, and concrete is supplemented into the pile hole. The invention discloses a treatment method for non-in-place steel bar planting of a long spiral drilling pressure grouting pile. A certain length of a section without bending moment and shearing force action of a pile foundation structure is taken as an allowable length for non-in-place steel bar planting. According to the method, the risk of failure of steel bar planting is reduced, the construction quality is improved, and the construction quality problem caused by improper steel bar planting is reduced. The construction method is used for construction of the long spiral drilling press-grouting pile.
本发明公开了一种长螺旋钻孔压灌桩植筋方法与植筋不到位的处理方法,涉及建筑施工领域,目的在于提高植筋成功率,提高施工质量,采用的技术方案是:长螺旋钻孔压灌桩植筋方法,制作长螺旋钻孔压灌桩的钢筋笼,钢筋笼的外侧安装滚轮,钢筋笼的底部或靠近底部的部位固定安装传力杆件,将导入装置与钢筋笼进行组装,将导入装置连同钢筋笼植入桩孔内的混凝土中,最后拔出导入装置,并向桩孔内补充混凝土。长螺旋钻孔压灌桩植筋不到位的处理方法,取桩基结构无弯矩和剪力作用段的一定长度作为植筋不到位的允许长度。本发明减小了植筋失败的风险,提高了施工质量,减少了因植筋不到位而导致的施工质量问题。本发明用于长螺旋钻孔压灌桩的施工。
