一种隧道用注浆锚杆止浆托盘
摘要：
本实用新型涉及一种隧道用注浆锚杆止浆托盘，包括托盘底板，所述托盘底板的中心部位设有梯形凸起，所述梯形凸起顶部设有通孔，所述通孔与托盘底板的夹角为15°～75°。该实用新型的止浆托盘既能适应与围岩呈不同角度注浆锚杆的止浆作用，还能更好的起到均匀传递压力，减少对注浆锚杆体的剪切力，使注浆锚杆获得最佳受力，有效增加注浆锚杆的承载能力，同时强度高，用料节省，加工方便，节约成本。
摘要（英）：

The utility model relates to a grouting anchor rod grout-stopping tray for a tunnel. The grouting anchor rod grout-stopping tray comprises a tray base plate, wherein a trapezoid protrusion is arranged on the central portion of the tray base plate, a through hole is formed in the top of the trapezoid protrusion, and the included angle of the through hole and the tray base plate is 15-75 degrees. The grouting anchor rod grout-stopping tray can be adapted to the grout-stopping action of a grouting anchor rod which is in different angle with surrounding rock, pressure can be better evenly transmitted, the shear force to a grouting anchor rod body is decreased, the optimal stress of the grouting anchor rod is achieved, the bearing capacity of the grouting anchor rod is effectively increased, meanwhile, the strength is high, materials are saved, machining is convenient, and cost is saved.
