Basalt fiber anchor rod
The invention discloses a basalt fiber anchor rod, a basalt fiber reinforced monomer is arranged in the anchor rod, the basalt fiber reinforced monomer is composed of basalt fiber filaments on the inner layer and a modified layer wrapping the basalt fiber filaments, and the basalt fiber filaments are formed by high-temperature melting, extruding and pulling of basalt. The modified layer is formed by mixing superfine chopped steel fibers and basalt fiber filaments in a resin base material and wrapping the basalt fiber filaments with the superfine chopped steel fibers and the basalt fiber filaments through extrusion thermal control molding. The basalt fiber reinforcement anchor rod has the advantages of being light in weight, high in strength, resistant to corrosion, capable of achieving self-detection and easy to machine, can meet various engineering requirements, can be manufactured in any specification and can be produced in batches. According to the selected ultra-weak grating fiber technology, thousands of grating fiber sensors can be arranged on a single fiber, and global monitoring of the anchor rod body and related surrounding rock bodies is achieved.
本发明揭示了一种玄武岩纤维锚杆，锚杆内布置有玄武岩纤维增强单体，所述玄武岩纤维增强单体由内层的玄武岩纤维长丝、以及包裹玄武岩纤维长丝的改性层构成，所述玄武岩纤维长丝由玄武岩高温熔融挤拉形成，所述改性层由树脂基材内混合超细短切钢纤维和玄武岩纤维长丝通过挤压热控成型包裹在玄武岩纤维长丝上构成。本发明的玄武岩纤维增强体锚杆凭借其轻量、高强、耐腐蚀、自我检测且易加工的优点，可适应各种工程需要，进行任意规格制作，批量化生产。选用的超弱光栅光纤技术，单根光纤上可服用的光栅光纤传感器数量可达数千个，实现对锚杆体以及相关围岩体的全局监测。
