This invention belongs to the field of rockburst prevention and support in coal mine roadways, specifically providing a spiral energy-absorbing component, a support frame including the component, and a construction method. The spiral energy-absorbing component and support frame involve several parts: the spiral energy-absorbing component, the invert arch, and the arch crown. In the initial stage of roadway excavation support, the spiral energy-absorbing component partially deforms to adapt to the cross-sectional shape.

After the internal support columns are fitted, the impact energy is absorbed through the plastic buckling of the component material and the concrete within the central columns, forming secondary support. The internal support provides the main support force for the steel-concrete composite structure. Therefore, this invention can achieve partial absorption of impact energy, improving the energy absorption level. Furthermore, it possesses a two-stage energy absorption buffer mechanism and a steel-concrete composite structure with extremely high load-bearing capacity, greatly improving the safety of roadway support.
