The invention relates to a prefabricated drilling device for a building pile. The prefabricated drilling device comprises a drill rod, an auxiliary frame, a jacking mechanism, a rotating and pressingmechanism and a dust falling mechanism, wherein the drill rod is inserted into the auxiliary frame, and a rotating sleeve used for enabling the drill rod to be inserted in a guiding mode and rotate stably in a guiding mode is arranged at the top of the auxiliary frame; a circle of clamping groove is formed in the inner wall of the rotating sleeve, and a circle of pressing rod mechanism is insertedinto the inner wall of the rotating sleeve; an annular plate is installed on an action rod of an electric cylinder, the dust falling mechanism is arranged on the annular plate, and the inner ring ofthe annular plate sleeves the outer side of the rotating sleeve; and the rotating and pressing mechanism connected to the outer part of the rotating sleeve can rotate, and the rotating and pressing mechanism can roll a soil layer around a drilled hole by utilizing bottom trundles, so that the soft soil layer with the periphery being upwards fluctuated during drilling can be compacted in a rollingmode after drilling is completed, the operation mode that after existing drilling, soil needs to be filled beside the hole manually, and then foot-stepping compaction is carried out is replaced, the working efficiency is improved, and meanwhile, the labor force is liberated.
本发明涉及一种建筑桩用预制钻孔装置，包括钻杆、辅助架、顶压机构、转压机构和降尘机构，所述钻杆插装于所述辅助架内，所述辅助架的顶部设置有用于令钻杆导向插入并导向平稳旋转的转套；所述转套的内壁开设有一圈卡槽和插装有一圈压杆机构，所述电动缸的动作杆上安装有环板，所述环板上设置有降尘机构，所述环板的内圈套于转套的外侧；可令转套外部所连接的转压机构旋转动作，并且旋转的转压机构会利用底部脚轮辊压所钻孔周边的土层，使得钻孔时周边向上起伏状松软的土层在钻孔完毕后得以辊压式夯实，代替现有的钻孔后，需要利用人工在孔边填土再进行脚踩压实的操作方式，提高了工作效率，同时解放了劳动力。
