Abstract
The invention discloses an arch support connecting method for enhancing the longitudinal stability between steel arch supports. The method relates to the field of tunnel and underground project excavation. According to the method, after the arch supports (1) are erected, a plurality of horizontal connecting rebars (2) are arranged between every two steel arch supports at intervals; furthermore, an obliquely connected rebar (3) is arranged between every two adjacent horizontal connecting rebars, and the horizontal connecting rebars and the obliquely connected rebar form a triangular structure with the steel arch supports, so that the problem of longitudinal instability between the steel arch supports in a traditional connecting method is effectively solved, the longitudinal stability between the steel arch supports is guaranteed, the great deformation of soft rock is controlled, safety risks during a construction process are greatly reduced, promotion and application in a large scope are suitable, the method is particularly applicable to tunnel construction processes, and is also applicable to the construction of underground projects.
