Hydraulic expansion type soil-squeezing anchor rod and using method thereof
The invention provides a hydraulic expansion type soil-squeezing anchor rod and a using method thereof. The hydraulic expansion type soil-squeezing anchor rod comprises an expansion mechanism, soil-squeezing steel discs, drawing reinforcing steel bars and a counter-force frame. The expansion mechanism is arranged in the soil-squeezing steel discs, one ends of the drawing reinforcing steel bars arefixed to the soil-squeezing steel discs, and the other ends of the drawing reinforcing steel bars are fixed to an external soil layer through the counter-force frame. The expansion mechanism comprises a hydraulic oil cylinder, expansion arms and a piston push head, wherein the hydraulic oil cylinder is connected with an external oil pump through an oil pipe, the piston push head is arranged in ahydraulic oil cavity in the hydraulic oil cylinder, the expansion arms are hinged to two external sides of a cylinder body of the hydraulic oil cylinder, and the other ends of the expansion arms are hinged to the inner walls of the soil-squeezing steel discs. According to the hydraulic expansion type soil-squeezing anchor rod, the hydraulic oil cylinder and the expansion arms are used as the expansion mechanism, so that the soil-squeezing steel discs are driven to squeeze a soil body to play a role in anchoring, the construction period can be greatly shortened, and the hydraulic expansion typesoil-squeezing anchor rod is a recyclable and environment-friendly anchor rod.
本发明提供一种液压扩张膨胀式挤土锚杆及其使用方法，包括膨胀机构、挤土钢片、拉拔钢筋以及反力架，所述膨胀机构设置在挤土钢片的内部，所述拉拔钢筋的一端固定在挤土钢片上，所述拉拔钢筋的另一端固定通过反力架固定在外部土层上，所述膨胀机构包括通过油管与外部油泵相连接的液压油缸、扩张臂以及活塞推头，所述活塞推头设置在所述液压油缸内部的液压油腔中，所述扩张臂铰接在所述液压油缸的缸体外部两侧，所述扩张臂的另一端与所述挤土钢片的内壁铰接。本发明提供的锚杆通过将液压油缸及扩张臂作为膨胀机构，进而带动挤土钢片挤压土体达到锚固的作用，可大大缩短工期，是一种可回收的绿色环保型锚杆。
