Device for controlling perpendicularity of prestressed concrete pipe pile
The invention discloses a device for controlling the perpendicularity of a prestressed concrete pipe pile. The device mainly comprises a clamp, a plumb and a dial, wherein the clamp is composed of anupper clamp and a lower clamp, the upper clamp is connected to a vertical rod through an upper cross rod, and the lower clamp is also connected to the vertical rod through a lower cross rod; and a plumb line is fixed on the upper clamp through a lifting hook, the plumb is connected to the lower part of the plumb line, a plumb point of the plumb makes contact with the dial, and the dial is fixed onthe lower cross rod. The device for controlling the perpendicularity of the prestressed concrete pipe pile has the following advantages that when the first section of the pile is pressed downwards, the perpendicularity is 0.3% (smaller than 0.5% as required by the standard), and in the construction process, the maximum perpendicularity deviation of a pile body is 0.5% (smaller than 1% as requiredby the standard); and the device for measuring the perpendicularity of the pile body is simple in structure and convenient to operate, the perpendicularity of the pile body of the prestressed concrete pipe pile is controlled in real time, the pile forming quality is improved, and the piling progress is accelerated.
本发明公开了一种控制预应力混凝土管桩垂直度的装置，其主要由卡箍、铅垂和刻度盘组成，卡箍由上卡箍和下卡箍组成，上卡箍通过上横杆连接到竖杆，下卡箍通过下横杆也连接到竖杆，铅垂线通过吊钩固定在上卡箍上，铅垂线下连接着铅垂，铅垂的垂尖接触到刻度盘，刻度盘固定在下横杆上。本发明具有以下优点：采用本发明第一节桩下压时垂直度为0.3%(小于规范要求为0.5%)；施工过程中，桩身垂直度最大偏差0.5%(小于规范要求为1%)，测量桩身垂直度的装置结构简单，操作方便，实时控制预应力混凝土管桩的桩身垂直度，提高成桩质量，提高打桩进度。
