Bagged hot-melt calabash body full-recovery anchor rod and construction method thereof
The invention belongs to the field of geotechnical engineering, and relates to a bagged hot-melt calabash body full-recovery anchor rod and a construction method thereof. The anchor rod is composed ofa high-strength bag (2), a hot-melt anchoring body (1) and an electric heating wire (3). According to the anchor rod, the outer surface of the high-strength bag (2) is designed to be in an uneven calabash shape, so that on one hand, the side resistance of the anchor rod is improved, and on the other hand, when the anchor rod is recovered, after the hot-melt anchoring body (1) is melted, by pulling the high-strength bag (2), the high-strength bag (2) generated from the outer anchor end can be stripped from a rock-soil body or a rock-soil reinforcing body on the outer side of the high-strengthbag (2) in a gradual damage form; and therefore the full-recovery and reuse of the anchor rod can be easily achieved, the full-recovery is achieved, the recovery can be easily achieved in narrow space, the bearing capacity is high, the manufacturing cost is low, and the construction speed is high.
本发明涉及岩土工程领域的一种袋装热熔性葫芦体全回收锚杆及其施工方法，该种锚杆由高强袋子(2)、热熔性锚固体(1)、电热丝(3)三部分组成，高强袋子(2)的外表面可设计为凸凹不平的葫芦形，一方面有助于提高锚杆侧阻力，另一方面，在锚杆回收时，将热熔性锚固体(1)熔化后，通过拉拔高强袋子(1)，有助于实现自外锚端发生的高强袋子(2)与其外侧的岩土体或岩土加固体以渐进破坏形式剥离，从而易于实现锚杆的全回收再利用，可全回收，易在狭小空间下实现回收，承载力高，造价低，施工速度快。
