Prestress PHC pipe pile pulling resistance detection device and detection method
The invention provides a prestress PHC pipe pile pulling resistance detection device. The prestress PHC pipe pile pulling resistance detection device comprises a flange plate and a jack with a digitaldisplay function, wherein supporting rods are arranged at the positions, close to the front side edge and the rear side edge, of the flange plate correspondingly; cross beams are arranged at the upper ends of the supporting rods located on the front side and the rear side of the flange plate; the jack is arranged above the flange plate; a cushion block is arranged above the jack; and the front portion and the rear portion of the cushion block abut against the lower sides of the cross beams on the corresponding sides. A detection method of the device comprises the following steps that the flange plate is installed on the upper end face of a pipe pile; sleepers are arranged on the left side and the right side of the flange plate, and a horizontally-arranged supporting beam is arranged on the two sleepers in a bearing manner; and the jack is placed on the supporting beam, the cushion block is arranged on the jack, the jack is started and reaches the preset thrust, the pipe pile top displacement situation is displayed in a jack digital display manner, and whether the pulling resistance reaches the standard or not is judged. The device is simple in structure and convenient to use. Thedetection method is simple in step, and the welding construction procedure is reduced through connection of the flange plate and the pipe pile.
预应力PHC管桩抗拔检测装置，包括法兰板和带有数显功能的千斤顶法兰板靠近前侧边和后侧边处分别设有支撑杆，位于法兰板前侧、后侧的支撑杆上端设有横梁；千斤顶布置于法兰板上方，千斤顶上方设有垫块，垫块前部、后部的与对应一侧横梁的下侧相抵靠。上述装置检测方法，包括以下步骤：将法兰板安装在管桩的上端面上；在法兰板左右两侧设置枕木，将一个水平布置的支撑梁担置在两个枕木上；将千斤顶放置在支撑梁上，将垫块安置在千斤顶上，启动千斤顶并使其达到预设的推力，通过千斤顶数显方式显示管桩顶部位移情况，判断抗拔性能是否达标。该装置结构简单使用方便。检测方法步骤简单，采用法兰盘与管桩连接减少了焊接施工工序。
