Anchoring-grouting integrated reinforcing method for roadway floors

The invention relates to an anchoring-grouting integrated reinforcing method for roadway floors. Aimed at the problems that the deep of the soft, fractured roadway floor in a geologically abnormal zone is hard to reinforce and floor heave is difficult to control, the anchoring-grouting integrated reinforcing method is adopted and comprises the following steps: severe grout runout or grout leakage is first prevented during grouting when the roadway floor is constructed, shallow hole grouting is then carried out to block shallow fractures and form a shallow grout-stopping layer, moreover, after grouting, the integrity of wall rocks within the grouting range is enhanced, and thereby the problem of subsequent grouting borehole collapse is solved; deep grouting holes are then constructed, grouting pipes and anchor ropes are mounted, full-length anchoring is carried out on the anchor ropes while grout is injected to solidify deep rocks, finally, channel steel, I-shaped steel and the like are adopted to combine single anchor ropes into anchor rope beams, and thereby the deformation of the roadway floor can be effectively controlled.
