Basalt fiber anchor rod double-grout-stopping-bag prestress structure and construction method thereof
The invention relates to a basalt fiber anchor rod double-grout-stopping-bag prestress structure and a construction method thereof. Through the arrangement of the steel bar sleeve connecting piece and the filling layer, the anti-shearing capacity of the basalt fiber anchor rod is effectively improved, the basalt fiber anchor rod can meet the requirement of pre-tensioning construction, and therefore the application range of the basalt fiber anchor rod in slope anchoring engineering is widened. And the grouting process is more accurate and efficient due to the arrangement of the double grout stopping bags (the first grout stopping component and the second grout stopping component). Through division of the hole bottom grouting section, the free section and the end grouting section, segmented control of the grouting process is achieved, grout leakage is effectively prevented, and the grouting effect is ensured. According to the method, the construction process is greatly simplified, and the construction efficiency is improved. Meanwhile, the pre-tensioning deformation composite structure effectively solves the problems that the basalt fiber anchor rod is prone to shear damage, low in pre-tensioning force value, insufficient in durability, prone to pre-stress relaxation and the like in the pre-tensioning process, and a new solution is provided for slope pre-stress anchoring engineering.
本发明涉及一种玄武岩纤维锚杆双止浆囊预应力结构及其施工方法。通过钢筋套管连接件和填充层的设置，有效提升了玄武岩纤维锚杆的抗剪切能力，使其能够适应预张拉施工的需求，从而拓宽了玄武岩纤维锚杆在边坡锚固工程中的应用范围。双止浆囊(第一止浆部件和第二止浆部件)的设置使得注浆过程更加精准和高效。通过孔底注浆段、自由段和端部注浆段的划分，实现了注浆过程的分段控制，有效防止了浆液泄露，确保了注浆效果。该方法大大简化了施工流程，提高了施工效率。同时，预张拉形变复合构造有效解决玄武岩纤维锚杆预张拉过程中易受剪切破坏、预张拉力值低、耐久性不足、预应力易松弛等问题，为边坡预应力锚固工程提供了一种新的解决方案。
