Groove backfilling structure based on self-compacting backfilling material and construction method thereof
The invention provides a groove backfilling structure based on a self-compacting backfilling material, which comprises a leveling sand cushion layer, a pipeline support, a pipeline, a first backfilling layer, a second backfilling layer and a pipeline groove, the leveling sand cushion layer is arranged on the bottom wall of the pipeline groove, the pipeline support is arranged on the top wall of the leveling sand cushion layer, the pipeline is arranged on the pipeline support, and the second backfilling layer is arranged on the pipeline support. The first backfill layer is arranged on the top wall of the leveling sand cushion layer and wraps the pipeline support and the pipeline, the second backfill layer is arranged on the top wall of the first backfill layer, and the top wall of the second backfill layer is flush with the ground. The groove backfill soil adopts the flow-state soil with certain flowing property, so that self-compaction of the backfill material can be effectively realized, the pipe-soil synergistic effect is realized, the stress state of the pipeline is improved, the loss of the backfill material is reduced, the quality of the drainage pipeline is improved, and pipeline interface disengagement, pipeline fracture and pavement collapse are avoided.
本发明提供了一种基于自密实回填材料的沟槽回填结构，包括找平沙垫层、管道支座、管道、第一回填层、第二回填层以及管道沟槽，找平沙垫层设于管道沟槽底壁，管道支座设于找平沙垫层顶壁，管道设于管道支座上，第一回填层设于找平沙垫层顶壁，第一回填层包裹着管道支座和管道，第二回填层设于第一回填层顶壁，第二回填层顶壁和地面齐平。本发明沟槽回填土采用具有一定流动性能的流态土，能够有效实现回填材料的自我密实，实现管土协同作用，改善管道受力状态，减少回填材料流失，提高排水管道质量，避免管道接口脱开、管道破裂及路面塌陷发生。
