The invention discloses a solid pipe grouting method of a broken layer. The solid pipe grouting method of the broken layer comprises the following steps that first drilling is carried out, reaming iscarried out, lowering of a first core barrel is carried out, and a pressure-tight test is carried out, wherein two times of hole washing, the second drilling, reaming, and lowering of a second core barrel by adopting drill pipes one by one and the pressure-tight test are included. The solid pipe grouting method of the broken layer has the beneficial effects that the accumulated water can be discharged twice, so that the accumulated water removal work is ensured; furthermore, the problem of long-distance pipe lowering in the broken layer is solved by adopting a mode of sectioned lowering of thesecond rock barrel meanwhile, the power of a drilling machine is adopted to lower a pipe, so that the labor intensity of workers is reduced, and the safety during pipe lowering is ensured; in addition, coring bits and reducer joints with corresponding diameters can be separately machined according to the requirements of different water exploration and drainage drilling pipe lowering to solve theproblem of pipe lowering of the core barrels with various diameters.
