Prestressed grouting anchor rod with hydraulic telescopic sleeves, grouting system and method
The invention discloses a prestressed grouting anchor rod with hydraulic telescopic sleeves, a grouting system and a method. The prestressed grouting anchor rod comprises an inner rod and an outer rodwhich are sleeved together; the inner rod is of a hollow structure, the interior of the inner rod is used for being filled with hydraulic oil; a plurality of the telescopic sleeves communicating withthe interior of the inner rod are connected to the inner rod; the telescopic sleeves penetrate through holes reserved in the outer rod; the head of the inner rod and the head of the outer rod are both connected with a conical head; the tail of the inner rod is sealed by a first sealing baffle; threads are arranged at the tail of the inner rod; the threaded inner rod is matched with a screw, and oil pressure in the outer rod is adjusted by rotating the screw; the tail of the outer rod is sealed by a second sealing plate; a cavity is formed between the outer rod and the inner rod; a grouting pipe is arranged in the cavity; and a grout outlet hole is formed in the outer rod.
本发明公开了一种带液压可伸缩套筒的预应力注浆锚杆、注浆系统及方法，注浆锚杆包括套装一起的内杆和外杆，所述的内杆为中空结构，内部用于填充液压油，在内杆上连接有多个与其内部相连通的可伸缩套筒，可伸缩套筒穿过外杆上预留的孔；内杆和外杆头部均与锥形头相连，内杆的尾部由第一密封挡板密封，且内杆尾部设有螺纹，通过该螺纹内杆与一个螺丝配合，通过旋转螺丝调整外杆内部的油压；外杆的尾部由第二密封板密封，外杆和内杆之间形成空腔，在该空腔内设有注浆管，在外杆上设有出浆孔。
