Relocation and transformation construction process of rain sewage pipeline
The invention discloses a relocation and relocation construction process of a rain sewage pipeline. The relocation and relocation construction process comprises the following steps: (1) surveying and setting out; (2) pipeline trench detection work; (3) trench excavation; (4) pipeline foundation construction; (5) pipeline installation; (6) construction of an inspection well; (7) performing a closed water test; (8) hook head construction; and (9) backfilling and compacting the groove. The construction operation is simple, the stability is high, the effect after relocation is good, and the safety and efficiency of relocation and relocation of the underground pipeline are effectively improved. In the migration and modification process, damage to other pipelines can be well avoided through the exploring ditch, and construction safety is ensured. Over-excavation is avoided during trench excavation, disturbance to a base surface and a side slope is avoided, segmented excavation is adopted, one segment is excavated, and the pipeline is immediately laid to complete one segment backfilling, so that the trench can be prevented from being exposed for a long time, and trench collapse and potential safety hazards are reduced.
本发明公开了一种雨污水管线的迁改施工工艺，包括以下步骤：(1)测量放线；(2)管线探沟工作；(3)沟槽开挖；(4)管道基础施工；(5)管道安装；(6)检查井施工；(7)闭水试验；(8)勾头施工；(9)沟槽回填、压实。本发明施工操作简单，稳定性高，迁改后效果好，有效提高了地下管线迁改的安全性和效率。在迁改过程中通过探沟能够很好地避免对其它管线的破坏，确保施工安全。沟槽开挖时避免了超挖情况的出现，不会对基底面和边坡产生扰动，采用分段开挖，开挖一段，立即铺设管道回填完成一段，从而能够防止长时间将沟槽暴露，减少了沟槽塌方及安全隐患。
