Treatment method of buried water pipeline foundation
The invention provides a buried water pipeline foundation treatment method which comprises the steps that a soil layer in a preset range is excavated, and a plurality of PHC piles are arranged below an exposed substrate layer; laying a mattress layer on the substrate layer; a pipeline cushion layer is arranged on the mattress layer; and a plurality of water pipelines are placed on the pipeline cushion layer at intervals and are backfilled to form a pipeline backfilling soil layer, and the pipeline backfilling soil layer is backfilled to form a natural soil backfilling soil layer. According to the embodiment, the multiple PHC piles are arranged below the base layer, the soft soil layer below the base layer can be extruded, the strength of the soft soil layer is improved, then the bearing capacity of the soft soil layer is improved, and sedimentation of the soft soil layer is reduced. In addition, the mattress layer can prevent displacement from directly affecting the water pipeline, and the effect of protecting the water pipeline is achieved. And finally, a pipeline backfill soil layer and a natural soil backfill soil layer are formed through backfill, the effect of stabilizing the water pipeline can be achieved, and meanwhile the bearing capacity of the foundation for ground loads is improved.
本发明提供了一种埋地水管道地基的处理方法，包括挖除预设范围的土层，在露出的基底层下设置多个PHC桩；在基底层上铺设褥垫层；在褥垫层上设置管道垫层；在管道垫层上间隔地放置多个水管道并回填形成管道回填土层在管道回填土层上回填形成自然土回填土层。该实施方式通过在基底层下设置多个PHC桩能够挤压基底层下软土层，提高软土层强度，进而提高软土层的承载力，减少软土层发生沉降。此外，褥垫层能够避免位移直接对水管道产生影响，起到了保护水管道的作用。最后，通过回填形成管道回填土层和自然土回填土层，能够起到稳定该水管道的作用，同时提高该地基对于地面载荷的承载能力。
