Pile casing device of full-rotation drilling machine
The invention provides a pile casing device of a full-rotation drilling machine. The device comprises a steel pile casing, a cutting section, a protection mechanism and a plurality of cutting tool bits, wherein the steel pile casing and the cutting section are both of a hollow cylindrical structure, the steel pile casing is connected with a first end of the cutting section, the plurality of cutting tool bits are arranged on the end face of a second end of the cutting section, and the protection mechanism is arranged on the steel pile casing and the cutting section and used for preventing piping. According to the device, the protection mechanism is arranged on the steel pile casing and the cutting section, in the drilling and soil taking process of the full-rotation drilling machine, the protection mechanism can reinforce a soil body at the bottom of a drilled hole and play a water stopping role so as to prevent a piping phenomenon, then smooth construction is guaranteed, the safety ofsurrounding buildings is guaranteed, the device can adapt to various working conditions, especially under complex working conditions of a thick sand soil layer, a high water level and the like, the piping phenomenon can be more effectively prevented, the construction quality can be guaranteed, and the construction efficiency can be improved.
本发明提供了一种全回转钻机的护筒装置，该装置包括：钢护筒、刀削节、防护机构和多个切削刀头；其中，钢护筒和刀削节均为内部中空的筒状结构，钢护筒与刀削节的第一端相连接，刀削节的第二端的端面设置有多个切削刀头；防护机构设置于钢护筒和刀削节，用于防止出现管涌现象。本发明中，在钢护筒和刀削节上设置有防护机构，在全回转钻机钻孔及取土过程中，防护机构能够对钻孔孔底的土体进行加固，起到止水作用，以防止出现管涌现象，进而保证施工的顺利进行，确保了周围建筑的安全，并能适应各种工况，尤其是较厚砂土层且高水位面等的复杂工况，能够更有效地防止出现管涌现象，还能保证施工质量并提高施工效率。
