Information

  Hollow bolt combination Hollow bolt plays an important role in the support of roads, railways and tunnels, and its main uses are as follows:

  Radial reinforcement: The hollow anchor rod replaces the traditional mortar bolt for radial reinforcement. Hollow grouting bolts can completely solve the defects of insufficient grouting and inability to achieve grouting during the construction of traditional mortar bolts, thereby ensuring the quality of the project.

  Slope reinforcement: the use of hollow anchor rods to reinforce unstable slopes is not only simple in technology, low in cost, but also convenient and quick in construction and effective.

  Foundation pit support: Hollow anchor rods are used to reinforce the foundation pits of buildings. Not only the process is simple, but also grouting can be achieved to improve the surrounding rock conditions of the foundation pit.

  The combined hollow anchor rod is composed of a hollow full-threaded rod body, anchor head, mud plug, backing plate, nut, etc. Each part of them will maximize the filling and density during the grouting process. Under pressure, the mortar will penetrate into the cracks in the surrounding rock (specific parameters depend on the design), and the hollow bolt can also be easily installed with washers and nuts .

  What are the requirements for using hollow anchor rod support structure?

  The combined hollow anchor rod is suitable for the upward inclination of arches or anchor holes.

  When the composite hollow anchor rod is used for the downward tilt of the anchor rod, the angle of the anchor rod should not be greater than 30°.

  When grouting the composite hollow bolt, the mortar enters the anchor hole through the hollow inner hole of the hollow bolt body, the mortar in the anchor hole is filled from the outside to the inside, and the air in the anchor hole is discharged from the anchor rod. exhaust pipe. After grouting is completed, the plug should be installed immediately.
