Large-span roadway support structure

The invention discloses a large-span roadway support structure. The large-span roadway support structure comprises a plurality of groups of roadway supports sequentially connected in a head-to-tail mode, and every two adjacent groups of the roadway supports are connected in a limiting mode through hinges, so that the angles between the every two adjacent groups of roadway supports are adjusted soas to adapt to the direction of a roadway. Monitoring assemblies are further arranged between the every two adjacent groups of the roadway supports, the monitoring assemblies can monitor the relativesettlement amount of a certain roadway support, when the relative settlement amount exceeds a certain threshold value, the monitoring assemblies can feed back a signal to a control center, so that thesupports of the position are corrected and adjusted under the drive of a hydraulic pump station to prevent the situation from deteriorating. 本发明公开了一种大跨度巷道支护结构，其包括多组依次首尾相接的巷道支护，且相邻的两组所述巷道支护采用铰链的形式进行限位连接，从而能够调节相邻的两组巷道支护之间的角度，以便适
