Fermented groove backfilling construction technology

The invention discloses a fertile groove backfilling construction technology, and relates to the technical field of fertile groove backfilling, and the fertile groove backfilling construction technology comprises the steps that S1, a drainage well foundation is constructed at the corner position of a foundation pit; s2, cleaning the bottom of the fertilizer tank, and laying a water seepage and drainage pipeline which is communicated with a drainage well; s3, sequentially constructing a waterproof coiled material and a compaction layer above the water seepage and drainage pipeline; s4, performing layered backfilling and layered tamping in the fertilizer groove; s5, when the backfill soil is backfilled to the position 0.3-0.5 m away from the earth surface, two circles of main drainage channels are buried, and the main drainage channels are communicated with the drainage well; s6, an auxiliary drainage channel is buried according to the construction drawing, and the two ends of the auxiliary drainage channel com
