Percussion drill cast-in-place pile construction device and construction method thereof
The invention relates to a percussion drill cast-in-place pile construction device. The construction device comprises a rack, a drill hammer, a driving mechanism and a traction rope, wherein a monitoring mechanism and a control mechanism are arranged on the rack, the monitoring mechanism is used for monitoring the deviation angle of the section, close to the drill hammer, of the traction rope, thecontrol mechanism is used for controlling the driving mechanism to prevent the traction rope from being released, the monitoring mechanism comprises a vertical auxiliary part, a distance testing unitand an angle calculating unit, the vertical auxiliary piece is hung on the rack, the distance testing unit is arranged at the free end of the vertical auxiliary piece and used for testing the horizontal distance between the free end of the vertical auxiliary piece and the section, close to the drill hammer, of the traction rope to serve as the offset distance, and the angle calculating unit is connected with the distance testing unit and is used for receiving the offset distance and calculating an offset angle according to the offset distance and a preset calculation formula. The constructiondevice has the effect of enabling the inclination angle of a pile hole to be within the specified inclination range so as to improve the construction quality of the pile foundation.
本申请涉及一种冲击钻灌注桩施工装置，包括机架、钻锤、驱动机构和牵拉绳，所述机架上设置有监测机构和控制机构，所述监测机构用于监测牵拉绳靠近钻锤一段的偏移角度，所述控制机构用于控制驱动机构以阻止对牵拉绳的释放；所述监测机构包括垂直辅助件、距离测试单元和角度计算单元；所述垂直辅助件挂接于机架上；所述距离测试单元设置于垂直辅助件的自由端，用于测试所述垂直辅助件的自由端与所述牵拉绳靠近钻锤一段之间的水平间距作为偏移距离；所述角度计算单元与距离测试单元连接，用于接收所述偏移距离，并根据所述偏移距离与预设的计算公式计算出偏移角度。本申请具有使桩孔的倾斜角度位于规定的倾斜度范围内，以提高桩基施工质量的效果。
