The invention relates to a segmented hollow grouting anchor rod for segmented grouting with a pulp stop connecting sleeve, and belongs to the field of construction engineering. The segmented hollow grouting anchor rod for segmented grouting with the pulp stop connecting sleeve comprises an anchor rod anchoring head, an anchor head connecting thread section, a hollow anchor rod first section, an anchor rod connecting sleeve grouting hole, a pulp stop function anchor rod connecting sleeve, a hollow anchor rod second section, an anchor rod memory pulp stop plug, an anchor rod arch cushion plate,an anchor rod spherical nut and an anchor rod grouting hole; the hollow anchor rod first section and the hollow anchor rod second section both adopt a threaded connecting mode, wherein the hollow anchor rod first section is connected with the anchor rod anchoring head and the pulp stop function anchor rod connecting sleeve; the anchor rod grouting hole is formed in the bottom of the hollow anchorrod second section; and the bottom end thereof is connected with the anchor rod memory pulp stop plug, the anchor rod arch cushion plate and the anchor rod spherical nut in sequence. The segmented hollow grouting anchor rod for segmented grouting with the pulp stop connecting sleeve has the effects and the advantages of good integrity, convenience to construct, high construction speed, good economical effect, convenience to transport, segmented grouting design, compact grouting, good effect and reduction of the production cost.
Description
technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a segmented hollow grouting bolt with a grouting connecting sleeve for segmented grouting. Background technique [0002] Anchor technology refers to drilling a hole in a natural formation to a stable formation, inserting a bolt, and then pouring cement mortar into the hole. With the help of the longitudinal tension of the bolt body, it overcomes the fact that the tensile capacity of rock and soil is far lower than the compressive capacity. shortcoming. Anchor rods, as a member system structure for rock and soil reinforcement, are increasingly used in a wide variety of engineering projects. Bolt support has developed rapidly in coal mines, non-coal mines, tunnels and other geotechnical engineering. Now it has been widely used in projects such as slopes, tunnels, railways, highways, water conservancy projects, dams, bridge foundations, riversides, high-rise bui...
