Method for treating broken pile defect of precast pile in soft soil area
The invention discloses a method for treating a broken pile defect of a precast pile in a soft soil area, and relates to the technical field of civil construction. B, manual hole digging; c, artificial red brick wall protection; d, the broken pile body is broken manually; e, small strain detection; f, lengthening the reinforcement cage; g, concrete pouring; h, maintenance is conducted, manual excavation and manual supporting are adopted, tedious procedures such as hoisting and installing of mechanical equipment can be avoided, time is short, and the site requirement is low. Fracture positions of an original precast pile are all removed, high-grade concrete is adopted to replace a fracture surface to a designed section pile body, a reinforcement cage can be lengthened strictly according to specification requirements, the quality is controllable, related mechanical property requirements can be met, pile repairing point positions do not need to be designed, a bottom plate structure does not need to be changed, related materials and manpower are saved, and the construction efficiency is improved. Meanwhile, the manufacturing cost is relatively low.
本发明公开了一种软弱土地区预制桩断桩缺陷处理方法，涉及土建施工技术领域，包括以下步骤：A.桩位测设；B.人工挖孔；C.人工红砖护壁；D.人工破处断裂桩身；E.小应变检测；F.钢筋笼接长；G.混凝土浇筑；H.养护，采用人工开挖、人工支护，能够避免机械设备吊运、安装等繁琐工序，时间短，场地要求低。本发明将原预制桩的断裂处全部剔除，采用高标号混凝土代替断裂面至设计标段桩身，钢筋笼可严格按规范要求接长，质量可控，能满足相关力学性能要求，且无需设计补桩点位，无需更改底板结构，节省了相关材料及人力，同时本发明的造价比较低。
