Category: Self propelled, expansion shell here today to tell you about expansion shell hollow grouting anchor: shell made of steel anchor head up, hollow grouting anchor body, only the pulp plug, plate and nut and connecting sleeve composition . Hollow bolt grouting medium suitable for geological conditions, permanent support and advance support. Bolt through the hollow rod of pressure grouting, broken rock consolidation can be achieved, cut off groundwater and purpose rod corrosion can rapidly form supporting force, control and stability of surrounding rock. Suitable for railways, highways, tunnels, mines, water conservancy hub, slope, dams, bridge group, Jianghai Lake River, and building high-rise building foundation reinforcement works. Expansion shell bolt grouting main technical parameters: Specifications LY25 LY27 LY28 LY32 maximum prestressing (KN) 80 100 100 120 anchor head diameter (mm) 52 58 58 65 anchor body LH25 LH27 LH28 LH32 Remarks tensile strength and length Construction can be designed according to customer requirements production process: A. prestressed anchor head installation and prestressing 1, drilled shaped and thoroughly clean hole; 2, mounted up shell anchor rod is inserted directly into the bottom of the first hole; 3) preload force rod, ensure the anchor head to the top and bottom and left-handed against the bolt body tightened up, and then install the pulp stopper, plate and nut; 4) connecting conventional tensioning tool (such as bolt tension meter), implementation prestressed tension to a predetermined value. B, grouting grouting purpose is to make a slurry wrapped prestressed anchor body, effectively prevent corrosion resulting rod bolt failure; at the same time, the slurry filled fracture, improve the surrounding rock. So, pay attention to the quality of the grouting must ensure full grouting should be supporting a special grouting and grouting joints, in order to ensure the effectiveness of the entire prestressed anchorage system.
