The invention discloses a
reinforced concrete pipe culvert dredging method. The method comprises the following steps of S1, sealing off the upstream end of a to-be-dredged
pipe culvert, and guiding upstream flowing water into the downstream of the to-be-dredged
pipe culvert through a temporary pipeline; S2, adding one or more of the following materials into the to-be-dredged pipe culvert: a
sludge curing agent, sandy soil and soil; S3, uniformly stirring and mixing the materials added in the step S2 with the
sludge by adopting a stirring device; and S4, excavating the mixed
sludge stirred in the step S3 by adopting an
excavator, and pouring the excavated sludge into a loading box of a sludge loading vehicle. The upstream of the to-be-dredged pipe culvert is sealed off, so that the upstream flowing water is prevented from entering the to-be-dredged pipe culvert, and the
adverse effect of the flowing water on subsequent sludge fixation can be effectively prevented; and meanwhile, the upstream flowing water is introduced into the downstream of the to-be-dredged pipe culvert through the pipeline, the upstream water accumulation pressure can be effectively relieved, and normal upstream flowing water is guaranteed.
