Manual hole digging construction method for cast-in-place pile
The invention discloses a manual hole digging construction method for a cast-in-place pile. The manual hole digging construction method for the cast-in-place pile comprises the following steps that a site around an orifice of a cast-in-place pile hole is mechanically or manually cleaned and leveled; the orifice part of the cast-in-place pile hole is excavated to the rock surface, and then concrete with a certain height is poured along the periphery of the orifice; a rock core around the cast-in-place pile hole is drilled; a central rock mass is excavated; after the central rock mass is lifted out, residual rock masses on the hole wall and the hole bottom are cleaned, and excavation of the layer is completed; and next-layer excavation is conducted till a designed depth is reached, and overall hole digging construction of the cast-in-place pile hole is completed. The manual hole digging construction method for the cast-in-place pile has the advantages of being simple in process, low in cost, high in adaptability and high in construction efficiency.
一种灌注桩人工挖孔施工方法，采用机械或人工清理、平整灌注桩孔孔口周围场地；灌注桩孔孔口部位开挖到岩石面，然后沿孔口周圈浇筑一定高度的混凝土；钻取灌注桩孔周边岩芯；中心岩体开挖；中心岩体吊出后，对孔壁和孔底残留岩体进行清理，完成本层开挖；进行下一层开挖，直至开挖到设计深度，完成灌注桩孔整体挖孔施工。本发明具有工艺简单、成本低、适应性强、施工效率高的优点。
