Grouting-free recyclable anchor rod based on electromagnetic effect and construction method thereof
The invention relates to the technical field of anchor rod supporting, and provides a grouting-free recoverable anchor rod based on the electromagnetic effect and a construction method thereof.The grouting-free recoverable anchor rod comprises an electromagnet assembly, a permanent magnet assembly and a rotary telescopic assembly; the electromagnet assembly comprises a threaded rotating shaft, a coil and an anchor rod body. The threaded rotating shaft is connected with the anchor rod body; the permanent magnet assembly surrounds the outside of the anchor rod body; the permanent magnet assembly is provided with a channel. The rotary telescopic assembly comprises a chain type blade and a gear; the gear is fixed on the anchor rod body; the chain type blade comprises a plurality of hinged blade units, each blade unit is meshed with the gear, one end of the chain type blade is a fixed end, and the other end of the chain type blade is a movable end; and the blade units of the chain type blade centrifugally move to penetrate through the channel one by one and be embedded into the soft soil foundation, or centripetally move to retract from the soft soil foundation one by one. The anti-pulling and anti-pressure characteristics of the anchor rod are effectively improved, and cyclic utilization of the anchor rod is achieved.
本申请涉及锚杆支护技术领域，提供了一种基于电磁效应的免注浆可回收锚杆及其施工方法，包括：电磁体组件、永磁组件以及旋转伸缩组件；电磁体组件包括螺纹转轴、线圈和锚杆本体；螺纹转轴与锚杆本体连接；永磁组件包围在锚杆本体的外部；永磁组件上设置有通道；旋转伸缩组件包括链式叶片和齿轮；齿轮固定于锚杆本体上；链式叶片包括多个相铰接的叶片单元，每个叶片单元与齿轮啮合，链式叶片的一端为固定端，另一端为活动端；链式叶片的叶片单元离心运动以逐一的穿过通道且嵌入至软土地基中，或向心运动以逐一的从软土地基中缩回。本发明有效提高锚杆的抗拔抗压特性，实现了锚杆的循环利用。
