Spray anchor support is a new type of underground support structure. It is in terms of the old overall lining, saving labor, save material, speed up the progress and reduce labor intensity and so on. From the role of the structure, shotcrete and rock bolting support closely with the surrounding rock and infiltrate into the crack, strengthening the weak structural plane, restraining the development of deformation, enhancing the stability of the surrounding rock itself and participating in the joint work of the surrounding rock to form a wide A good overall structure. This form of support, the past in the new railway tunnel and more
