Tunnel reinforcement materials
There are two main categories, organic and inorganic. Although organic polymer solution grouting materials have good permeability and gelation time can be controlled, most of their grouting materials have varying degrees of toxicity, which is easy to cause environmental pollution, and their cost is high, which limits The scope of application. Inorganic (there are three kinds of grouting materials: cement slurry series, cement-water glass series and water glass series) these three kinds of slurries are easy to mix and economical, especially for the environment without pollution and are widely used. Especially the cement-water glass series grouting materials have good characteristics.
Reinforcement material composition
The A and B component materials are mixed according to the volume of 1:1 and then uniformly injected into the loose and weak rock formations of the tunnel. After being bonded to the rock formations, the compressive strength is high and can well penetrate into the fine cracks of the rock formations. Used for tunnel loose rock formation, tunnel lining maintenance, reinforcement and sealing of gushing section. Its adhesion and mechanical properties are excellent, and it is easy to produce high adhesion with loose rock formations, which can effectively reinforce and seal the treated area, and improve the integrity and stress resistance of loose and weak rock formations.
