Anchor rod for geotechnical engineering
The invention relates to an anchor rod for geotechnical engineering. The anchor rod comprises a sleeve, a core rod and a reaming mechanism. The outer wall of the casing pipe is provided with a spiral groove which is concave towards the peripheral wall of the casing pipe, the left end of the casing pipe is provided with a drill bit which seals an opening in the left end of the casing pipe, and the outer wall of the drill bit is provided with a plurality of protruding edges which are in an annular array shape. The multiple reaming mechanisms are arranged in the length direction of the sleeve, each reaming mechanism comprises multiple reaming assemblies in an annular array shape along the central axis of the core rod, the reaming assembly on the upper side of the core rod comprises a reaming piece and a guiding piece, and the reaming piece comprises a containing groove, a first plate body and a connecting rod. The invention provides an anchor rod for geotechnical engineering to solve the problem of slippage instability caused by low tensile strength of an anchor rod in a rock-soil system with loose soil texture, and the anchor rod for geotechnical engineering can improve the connection between the anchor rod and the rock-soil system and provide better support for rock-soil.
本发明涉及一种岩土工程用锚杆，包括套管、芯杆和扩孔机构；所述套管的外壁上设置有向套管周壁凹陷的、螺旋状的凹槽，套管的左端设置有封闭套管左端开口的钻头，所述钻头的外壁上设置有多个呈环形阵列状的凸楞；所述扩孔机构有多个，多个所述扩孔机构沿套管长度方向设置，每个所述扩孔机构均包括多个沿芯杆中轴线呈环形阵列状的扩孔组件，芯杆上侧的所述扩孔组件包括扩孔件和导向件，所述扩孔件包括容纳槽、第一板体和连接杆。本发明为解决锚杆在土质松散的岩土体系中抗拉性不强，进而导致滑移失稳的问题，提供一种岩土工程用锚杆，能够提高提高锚杆和岩土体系的连接，提供给岩土更好的支护。
