  • System and construction method of single-layer lining tunnel structure based on mine-tunnelling method
    Patent number: 11821316
    Abstract: Provided are a system and construction method of a single-layer lining tunnel structure based on a mine-tunnelling method. With the single-layer lining tunnel structure, a structural rigidity and durability of the tunnel are improved. A construction process of sprayed concrete is improved, specifically, compactness agent and durability enhancing fiber are added to concrete to improve the compactness of concrete, and a special spraying process is adopted to reduce a bound rate of the concrete, and thus to improve the impermeability of sprayed concrete to reach a impermeability level of waterproof concrete. Steel fiber, cellulose fiber, synthetic fiber and other materials are added into the concrete can improve the tensile strength, crack resistance and durability of the concrete.
