Guide hole type static pile driver and construction method of guide hole type static pile driver
The invention provides a guide hole type static pile driver. The guide hole type static pile driver comprises a static pile driver, a side pile and guide hole equipment, the hole guiding equipment comprises a hole guiding base and a hole guiding mechanism, the hole guiding base is installed on the static pile driver, the hole guiding mechanism is detachably installed on the hole guiding base, the hole guiding base is at least provided with a first installation position and a second installation position, and when the hole guiding mechanism is installed at the first installation position, the hole guiding mechanism corresponds to a pile pressing mechanism of the static pile driver. The hole guiding mechanism is arranged corresponding to the pile pressing mechanism of the side pile when being mounted at the second mounting position; the hole guiding mechanism comprises a hole guiding device and a spiral drill rod, the spiral drill rod is installed on the hole guiding device, the hole guiding device is used for driving the spiral drill rod to rotate, and the maximum diameter of the spiral drill rod is smaller than the diameter of the inner ring of the prefabricated pipe pile. Meanwhile, the invention further provides a construction method of the guide hole type static pile driver. Compared with the prior art, the guide hole type static pile driver and the construction method thereof can better guarantee the construction quality of the prefabricated pipe pile.
本发明提供了一种引孔式静力压桩机，其包括静力压桩机、边桩及引孔设备；引孔设备包括引孔底座及引孔机构，引孔底座安装于静力压桩机，引孔机构可拆卸安装于引孔底座，且引孔底座至少具有第一安装位置及第二安装位置，引孔机构安装于第一安装位置时对应静力压桩机的压桩机构设置，引孔机构安装于第二安装位置时对应边桩的压桩机构设置；引孔机构包括引孔装置及螺旋钻杆，螺旋钻杆安装于引孔装置，引孔装置用以带动螺旋钻杆转动，且螺旋钻杆的最大直径小于预制管桩的内圈直径。同时，本发明还提供了一种引孔式静力压桩机的施工方法。与现有技术相比，本发明提供的引孔式静力压桩机及其施工方法能更好的保障预制管桩的施工质量。
