Construction method of manual hole digging pile under slope topographic condition
The invention discloses a construction method of a manual hole digging pile under a slope topographic condition. The construction method comprises the following steps: constructing an orifice retainer and a bracket foundation on a slope; the support foundation comprises a first support foundation located on the upper side of the orifice retainer and a second support foundation located on the lower side of the orifice retainer. A scaffold operation platform is erected, and two supporting legs of the scaffold operation platform are located on the first support foundation and the second support foundation respectively; a soil body is excavated at the position of the manual hole digging pile, excavation is conducted downwards layer by layer in a segmented mode, dado concrete is poured in sequence, and prestressed anchor bars are constructed on the upper side of the dado in the construction process. The first support foundation and the second support foundation serve as supporting faces of the scaffold operation platform on the one hand and can serve as anti-slip belts of the hole opening protection ring on the other hand, the problem that the protection ring is subjected to unbalance loading during manual hole digging is solved, prestressed anchor bars are constructed on the upper side of the protection wall, stability of the protection wall is guaranteed, heavy excavation is avoided for operation, and the construction efficiency is improved. And the stability and safety of the operation platform are ensured.
本发明公开了一种斜坡地形条件下人工挖孔桩的施工方法，包括：在斜坡上施工出孔口护圈和支架基础；支架基础包括位于孔口护圈上侧的第一支架基础和位于孔口护圈下侧的第二支架基础；搭设脚手架操作平台，脚手架操作平台的两个支脚分别站位于第一支架基础和第二支架基础上；在人工挖孔桩的位置开挖土体，逐层分段向下开挖并依次浇筑护壁混凝土，且在施工过程中在护壁的上侧施工预应力锚筋。第一支架基础和第二支架基础一方面作为脚手架操作平台的支撑面，另一方面可以作为孔口护圈的抗滑带，解决了人工挖孔护圈受偏载的难题，在护壁的上侧施工有预应力锚筋，保证了护壁的稳定，避免大开挖进行作业，保证了操作平台的稳定与安全。
