The invention relates to the field of underground construction surrounding rock support and particularly to a supporting pressure adjustment roadway surrounding rock support method. The supporting pressure adjustment roadway surrounding rock support method utilizes an underground construction roadway yield
support system. The underground construction roadway yield
support system comprises yield hydraulic pillars, yield anchor bolts, meshes, a steel beam, a
pressure sensor and a controller. The meshes are laid on roadway surrounding rock, and the roadway surrounding rock is supported through the yield bolts; the steel beam is erected and performs roof support through the yield hydraulic pillars; every yield
anchor bolt comprises an anchoring head, one or more yield connectors, an elastic
cushion block, a W-shaped steel strip, a base plate, a yield device and a
handle nut, wherein the yield connector is used for connecting a left
anchor bolt body and a right
anchor bolt body and is a cavity, the two anchor bolt bodies are arranged inside the end portions of the cavity and provided with
piston stoppers, and springs are arranged between the
piston stoppers and the end portions of the connector cavity. Therefore, the supporting pressure adjustment roadway surrounding rock support method can achieve constant yield support according to actual geological surrounding rock stress situations, adjust the status of a
support system to form a good yield-support support
system and accordingly obtain optimized constant yield support.
