Recyclable anchor rod based on microwave loading expansion support
The invention discloses a recyclable anchor rod based on microwave loading expansion supporting, and belongs to the technical field of anchor rod supporting. Comprising an anchor rod assembly matched with a drill hole in a rock-soil body for anchoring, a microwave transmitting element and a pre-tightening component. The anchor rod assembly comprises an anchor rod connecting section and an anchor rod body, the anchor rod body is of a hollow structure, a microwave guide pipe is arranged in the anchor rod body, microwave conduction channels are formed in the microwave guide pipe and the anchor rod connecting section, and a plurality of liquid storage cavities are evenly distributed in the outer wall of the microwave guide pipe in the circumferential direction; a plurality of friction keys are evenly fixed to the outer wall of the liquid storage cavity in the axial direction at intervals. A key position opening matched with the friction key is formed in the anchor rod body, water in the liquid storage cavity is heated through microwaves generated by the microwave emitting element to enable the liquid storage cavity to expand, and then friction coupling anchoring of the friction key and the inner wall of a drill hole is achieved. According to the anchor rod device, the anchor rod can be expanded based on microwave energy loading so as to support a rock-soil body, an anchoring agent does not need to be used, full-length anchoring can be achieved, and dismounting and recycling are convenient.
本发明公开了一种基于微波加载膨胀支护的可回收锚杆，属于锚杆支护技术领域；包括与岩土体内的钻孔配合锚固的锚杆组件、微波发射元件和预紧构件；锚杆组件包括锚杆连接段和锚杆杆体，锚杆杆体为内部中空结构且其内设有微波导管，微波导管和锚杆连接段内均设有微波传导通道，微波导管的外壁上沿圆周方向均匀分布有多个储液腔体，储液腔体的外壁上沿轴向间隔均匀固定有多个摩擦键；锚杆杆体上设有与摩擦键配合的键位口，通过微波发射元件产生的微波加热储液腔内水使储液腔体膨胀，进而实现摩擦键与钻孔内壁摩擦耦合锚固。本发明的锚杆装置能够基于微波能加载使得锚杆膨胀进而支护岩土体，无需使用锚固剂，可实现全长锚固，且便于拆卸及回收再利用。
