Prestressed concrete pipe pile sinking method
The invention discloses a prestressed concrete pipe pile sinking method, which relates to the technical field of civil engineering pile foundation construction, and comprises the following steps: S1, arranging a site before pile sinking, detecting the bearing capacity of the site, and positioning a pile position from a control point through a total station; s2, the prestressed concrete pile entering the site is hoisted, after the concrete pile is in a vertical state, the pile tip is placed on the measured pile position through manual cooperation, then pile sinking is conducted, and pile conveying is conducted after pile sinking is completed; and S3, after the pile is conveyed to the designed elevation, whether a pile body is damaged or not is checked, and filling is conducted in the pipe pile after checking. According to the method, high-altitude and overground obstacles, an underground pipe network and the like on a construction site are treated, the leveling range of the site is generally the whole area within 4-6 m outside a building foundation, meanwhile, the bearing capacity of the foundation is not smaller than 100 KPa, a total station is used for positioning pile points in the leveled site, the axis of a building is led out from a network measuring control point, and the construction site is constructed. And the pile position is positioned through the axis.
本发明公开了一种预应力砼管桩沉桩方法，涉及土木工程桩基础施工技术领域，包括以下步骤S1沉桩前对场地进行整理，同时对场地的承载力进行检测，再通过全站仪从控制点对桩位进行定位；S2对进场的预应力砼桩进行吊装，将砼桩处于垂直状态后，由人工配合将桩尖放在测定后的桩位上后进行沉桩，沉桩结束后进行送桩；S3送桩至设计标高后，对桩身是否破损进行检查，检查后在管桩内进行填充。本发明将施工现场的高空、地上障碍物以及地下管网等进行处理，场地的平整范围一般为建筑物基础以外4～6m以内的整个区域，同时地基的承载力不得小于100KPa，在使用全站仪对平整后场地内的桩点进行定位，从测网控制点将建筑物轴线引出，通过轴线对桩位进行定位。
