Combined Bolt

An innovative support product integrating high-strength bolts, adjustable trays and highly efficient anchoring components. The anchoring depth and the strength of the rod body can be adjusted according to geological conditions, and different specifications of trays can be matched to cope with complex force scenarios. The products are mainly applied in fields such as underground mine roadways, tunnel construction, underground pipe galleries and deep foundation pit engineering.

It has high adaptability. A single system can be adapted to more than five geological conditions through component replacement
The dual guarantee of the pole body and the anchoring agent significantly reduces the risk of support failure, providing a solid support for the long-term stability of various projects
The installation is highly efficient. The pre-assembly design of components shortens the on-site operation time and reduces the construction difficulty
It has strong load-bearing capacity, and the combined structure disperses stress more evenly. The uplift resistance is over 30% higher than that of traditional anchor bolts
