Roadway supporting method of three-centered arch-shaped rigid support

The invention relates to the technical field of mine hole construction, and discloses a roadway supporting method of a three-centered arch-shaped rigid support, which comprises the following steps: S1, pretreating a roadway construction section; s2, all arch-shaped supports prepared in advance are installed in the roadway, and all the arch-shaped supports are fixed through foot-locking round steel; s3, the arched supports are welded and connected through deformed steel bars, and meshes are laid between the arched supports; s4, filling the gap between the mesh and the roadway construction section with a filler; and S5, the arch-shaped support, the meshes, the filler and the roadway construction section are sealed through concrete spraying supports. By means of the roadway supporting method, the roadway is supported on the premise that the size of the designed section of the roadway does not need to be changed, and operation and installation of follow-up equipment are not affected. 本发明涉及矿洞施工技术领域，公开了一种三心拱型刚性支架的巷
