Loose large-section roadway support technology
The invention provides a loose large-section roadway support technology. According to the rock stability condition in roadway tunneling, materials including water reducing agents, setting accelerators, steel fiber and the like are added into concrete, so that the concrete injection intensity is improved; the elasticity and plasticity performance is improved; an anchor rod (mesh) is cooperated for combined support; and the goal of large-section loose roadway fast support is achieved. The loose large-section roadway support technology well solves the problem of potential safety hazards such as wall caving and roof caving due to untimely support or non-ideal support effect of a large-section roadway, and has the characteristics that the efficiency is high; the energy consumption is low; the operation is flexible and convenient; the work intensity of workers is low; and the popularization and application prospects are wide.
