  Hollow bolts The combined hollow bolts play an important role in the support of highways, railways and tunnels.

Hollow bolt

  Brief introduction of safety measures for installation of hollow bolt recommended by Xinben:

 

  Radiation reinforcement: Use hollow bolts instead of traditional mortar bolts for radiation reinforcement. Through the application of hollow anchor rods, the lack of grouting of traditional mortar anchor rods in the construction process can be completely solved, and grouting cannot be achieved, 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 in construction, fast in speed, and effective. Hollow bolt manufacturers

 

  Hollow anchor rods are not only simple to reinforce the foundation pit, but also can realize grouting construction and improve the surrounding rock conditions of the foundation pit.

  The combined hollow anchor rod is composed of a hollow fully threaded rod body, an anchor head, a mud plug, a backing plate, and a nut. Its various parts can ensure the fullness and compactness of the grouting to the greatest extent. The mortar can penetrate into the cracks of the surrounding rock under pressure (according to the design). The hollow grouting bolt can also be easily installed with washers and nuts.

 

  The combined hollow anchor rod is suitable for upward tilting of the arch or anchor hole. Use hollow anchor rods in combination. When the anchor rod is inclined downward, the angle of the anchor rod shall not be greater than 30. When the hollow bolt is grouted, 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 exhaust pipe. After grouting is completed, it should be plugged immediately.
