The underground laying of water supply and drainage pipes should meet the requirements of drainage pipes for compaction and bearing capacity, and minimize uneven settlement. The bearing capacity of the foundation of pipelines and structures shall not be less than 100KPa; when the pipeline is located in a soil layer with a bearing capacity of <100KPa, the soil layer should be treated. If the depth of the soil layer is less than 1.0m, it should be completely removed and replaced with graded crushed stone, and compacted in layers, with a compaction coefficient of not less than 0.95; if the depth of the soil layer is greater than 1.0m, it should be excavated to 1.0m, and the lower layer should be filled with block stones and the upper layer with graded crushed stone, and compacted in layers, with a compaction coefficient of not less than 0.95; if the trench is in the filling section or the trench is over-excavated, the layer below the pipeline foundation must be compacted and backfilled in layers, with a density of not less than 95%, and light compaction should be used on both sides of the pipeline and within 0.5m above the top of the pipe. The height difference of the compacted surface on both sides of the pipeline should not exceed 0.3m. The trench backfill should be symmetrically backfilled from both sides of the pipeline, inspection wells and other structures at the same time to ensure that the pipeline and structures do not move. Limiting measures can be taken when necessary. However, in the prior art, when backfilling a trench, if the trench size is less than 90 cm, a small roller cannot perform uniform rolling and needs to be compacted manually, which is time-consuming and laborious.
