Trisection excavation method for manual hole digging circular pedestal pile
The invention discloses a three-part excavation method for a manual hole digging circular pedestal pile. The operation process of the excavation method comprises the following steps that a normal part of a pile body is excavated at a time according to a traditional technology, a retaining wall is poured, an expanded part of a pile foundation is divided into three parts to be excavated, and the method comprises the steps that firstly, an area 1 is excavated, and a temporary support is arranged; 2, excavating an area (2) and setting up a temporary support (2); 3, a temporary support (3) is arranged in the excavation area (3); fourthly, the first temporary support is dismantled, the first area is excavated downwards, after excavation is completed, the retaining wall is poured, the first temporary support is erected again, the fourth step is repeated in the second area, and the process is repeated till the designed hole depth is excavated. According to the utility model, the expanded base is excavated in three parts, and temporary supports are arranged at the same time. The protection wall can be prevented from falling, meanwhile, the device is suitable for excavation of various round expanded bore piles, special construction technologies and machines are not needed, construction is easy and convenient, the application range is wide, and the manufacturing cost is low.
本发明公开了一种人工挖孔圆形扩底桩三分开挖法；所述开挖法的操作流程如下：桩身正常部分按照传统工艺一次性开挖并浇筑护壁，桩基扩大部分均分为三个部分开挖，步骤一：开挖区域①，并设立临时支撑；步骤二：开挖区域②并设立临时支撑②；步骤三：开挖区域③设立临时支撑③；步骤四：拆除临时支撑①，把区域①往下挖，挖完后浇筑护壁重新架设临时支撑①，区域②重复步骤四，以此类推如此循环往复，直到挖到设计孔深。本专利扩底采用分为三个部分开挖，同时设立临时支撑。本专利能防止护壁下落，同时适用于各种圆形扩底桩开挖，且不需要特殊的施工工艺及机械，施工简便，适用范围广，造价低。
