Double-pile-casing positioning pile-forming construction method for cast-in-place pile of deep and thick rockfill layer of seawall
The invention discloses a double-pile-casing positioning pile-forming construction method for a cast-in-place pile of a deep and thick rockfill layer of a seawall. The double-pile-casing positioning pile-forming construction method comprises the following steps that a pile position center point is obtained through field measurement; cast-in-place pile hole guiding is conducted according to the pile position center point, and a pile position hole is formed; sinking the outer pile casing to the pile position hole according to the pile position center point to a bearing stratum; the position deviation value of the center point of the outer pile casing and the center point of the pile position is obtained through measurement; a positioning structure is installed on the outer pile casing according to the position deviation value, a positioning area is defined in the outer pile casing through the positioning structure, and the center point of the positioning area coincides with the center point of the pile position; the permanent inner pile casing vertically sinks to the bearing stratum along the positioning area in the outer pile casing; pulling out the outer pile casing; the bearing layer is rotationally excavated to form a pouring hole; and concrete is poured into the permanent inner pile casing and the pouring hole to form the pouring pile. According to the technical scheme, when the large-diameter cast-in-place pile of the coastal deep and thick rock-filled layer is constructed, unique superiority is highlighted in the aspects of improving the construction efficiency, guaranteeing the construction quality, controlling the construction cost and the like.
本发明公开一种海堤深厚填石层灌注桩双护筒定位成桩施工方法，包括以下步骤：在现场测量获取桩位中心点；根据桩位中心点进行灌注桩引孔，形成桩位孔；根据桩位中心点向桩位孔下沉外护筒至持力层；测量获得外护筒中心点与桩位中心点的位置偏差值；根据位置偏差值在外护筒安装定位结构，以通过定位结构在外护筒内限定形成定位区域，定位区域中心点与桩位中心点重合；外护筒内沿定位区域垂直下沉永久性内护筒至持力层；拔出外护筒；旋挖持力层形成灌注孔；向永久性内护筒以及灌注孔内浇灌混凝土，形成灌注桩。本发明技术方案对于滨海深厚填石层大直径灌注桩施工时，在提高施工效率、保证施工质量及施工成本控制等方面都突显出了独特的优越性。
