Abstract
The invention belongs to the technical field of backfilling, and discloses a red mudstone tamping and backfilling method for solving the problem that an existing red mudstone can not be largely used as a backfilling material. The method directly utilizes the red mudstone for tamping and backfilling, excavated red mudstones are fully utilized, and meanwhile, a compacting factor (0.94) required by construction can be met. Compared with a way in the prior art that a small quantity of red mudstones is used and other materials are used for replacement, the red mudstone tamping and backfilling method disclosed by the invention can greatly reduce and shorten days for construction and save construction cost.
