Construction method for integral type leveling and reinforcing structure of roadway bottom plate

The invention relates to the technical field of mine roadway reinforcing structures, in particular to a construction method of a roadway bottom plate integral type flat reinforcing structure, which comprises the following steps: cleaning a roadway bottom plate (1), paving and fixing a first geogrid (5) on the upper surface of the bottom plate (1), filling coal gangue on the upper surface of the first geogrid (5) to form a flat layer (2), and fixing the flat layer (2) on the bottom plate (1). A second geogrid (6) is laid and fixed on the upper surface of the leveling layer (2), a reinforcing layer (3) is laid on the upper surface of the second geogrid (6), and cement is poured on the reinforcing layer (3) to form a cement layer. According to the construction method of the integral type flat reinforcing structure of the roadway bottom plate, waste of the coal gangue can be recycled, the transportation cost of the coal gangue is saved, the roadway bottom plate can be reinforced, and the structural strength of th
