Construction method of cast-in-situ bored pile in unfavorable geology of slope terrain
The invention discloses a construction method of a cast-in-situ bored pile in unfavorable geology of a slope terrain. The construction method comprises the following steps: cleaning a site; constructing a pile foundation platform; pile testing; rechecking the bearing capacity of the pile foundation; embedding a pile casing; drilling holes; cleaning the hole; manufacturing, transporting and mounting a reinforcement cage; pouring concrete; and pile foundation quality detection. According to the construction method for the cast-in-situ bored piles in the unfavorable geology of the slope terrain, the construction organization is improved, a plurality of pile foundation platforms are built on different elevations through a step dividing method, a construction site is provided for mechanical equipment through the pile foundation platforms, the construction difficulty is lowered, and the construction period is shortened; and cost increase or construction period delay caused by uncertain factors in construction is reduced.
本发明公开了一种斜坡地形不良地质钻孔灌注桩施工工法，所述施工工法包括以下步骤：场地清理；桩基平台施工；试桩；桩基承载力复核；护筒埋设；钻孔；清孔；钢筋笼制作、运输及安装；混凝土灌注；桩基质量检测。所述斜坡地形不良地质钻孔灌注桩施工工法在施工组织上进行了改进，通过分台阶的方法在不同标高上建造若干个桩基平台，通过桩基平台为机械设备提供施工场地，降低了施工难度，缩短了施工工期，降低了施工中不确定因素造成的成本增加或工期延误。
