Abstract

The invention discloses a roadway support structure. The roadway support structure comprises a driving support part for conducting primary support on a roadway and a driven support part for conducting secondary support on the roadway. The driven support part supports the driving support part and comprises a plurality of steel pipes, and each pipe is filled with concrete. The roadway support structure is good in support effect, high in safety and stability and capable of ensuring the safety and continuity of production easily.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to a roadway support structure. Background technique [0002] Excavating a roadway in a high-stress and extremely broken rock mass is prone to roof collapse and severe shrinkage deformation in the roadway, which affects normal production and brings safety hazards. [0003] The support structure of the roadway in the related technology has poor support effect, and due to its limited bending stiffness and bearing capacity, the roadway often suffers from serious deformation such as roof sinking, two side convergence, and bottom heaving, which requires frequent repairs, safety and stability. poor. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a roadway support structure, which has the advantages of good support effect, high safety and stability...
